Answer:

x=8

Step-by-step explanation:

you first have to multiply 3times3 and 3 times 4 to get the fraction off

then you bring down 4(x-3)=20

then you multiply 4 times x which you will get 4x then 4 times3 which equals 12 sso you will write it like this 4x-12=20

the you take -12 and add it to 20 and you will get 32

the you just divide 32 and 4 and it will give you the answer

to check it if its right you do 4(8-3)=20

Answer:

Roughly 20.4%

Step-by-step explanation:

Use the formula of percent of error:

| Actual number - Guess / Actual number | (100)

The actual number is 108 and the guessed number is 86:

| 108 - 86 / 108 | (100)

= | 22/108 | (100)

= | 0.2037037037 | (100)

The vertical lines indicate absolute value.  This means that anything inside of it must be turned into its positive form.  Since it is already positive, just take the signs away:

0.2037037037(100)

≈ 0.204(100)

= 20.4

Turn this into a percent:

20.4%

Martha's percent of error is 20.4%

The equation of the line in fully simplified slope-intercept form is y = x + 7.

We have,

From the graph,

The coordinates of the line are:

(0, 7), (-7, 0), and (-2, 5).

We can use any coordinates the line touches on the graph.

We will use,

(0, 7) and (-7, 0)

The equation can be written in the form y = mx + c

m = (0 - 7) / (-7 - 0)

m = -7/-7

m = 1 ______(1)

And,

(0, 7) = (x, y)

So,

y = mx + c ______(2)

7 = 1 x 0 + c

7 = c

c = 7 ______(3)

Now,

From (1), (2), and (3).

y = x + 7

Thus,

The equation of the line in fully simplified slope-intercept form is y = x + 7.

Answer:

Some texts are missing from the question, I found a possible match, and here it is:

A particular country has total of 45 states. If the areas of 35 states are added and the sum is divided by 35​, the result is 135,600 square kilometres. Determine whether this result is a statistic or a parameter.

Answer:

The result is a statistic because the data involved are samples.

Step-by-step explanation:

A Parameter is a numerical representation of an entire population. That is they are numbers summarizing data for an entire population. In this case, if all the 45 states were measured, the result would have been a parameter.

On the other hand, statistics are numbers that are subsets (representative portions) of an entire population. Since 35 states were chosen out of 45 states, the average area of the 35 states is a statistic and not a parameter.

The hypotenuse of a right triangle will be $561$.

What is hypotenuse?

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.

Lengths of legs of a right triangle are given that are $264$ and $495$.

According to The Pythagorean Theorem,

\(hypotenuse^{2} = lenght^{2} + lenght^{2}\\hypotenuse^{2} = 264^{2} + 495^{2}\\\\hypotenuse^{2} = 69,696 + 245,025\\ hypotenuse^{2} = 314,721\\hypotenuse = 561\)

Answer:

i agree 100%

Step-by-step explanation:

The measure of angle D is 45°

Similar triangles have the same corresponding angle measures and proportional side lengths. When two triangles are similar, the corresponding angles are equal.

And also the ratio of corresponding sides of similar triangles are equal.

To know the corresponding angles

side AC is corresponding to side EF, therefore angle D is congruent to angle A

angle D = 45°

OR , we can use the sum of angles In a triangle , which is 180°

angle D = 180 -( 72+63)

= 180 - 135

The probability 1000, 1600, and 1776 were leap years according to the calendar used before the time of pope gregory, but 1492 was not.

The calendar used before the time of Pope Gregory was the Julian Calendar, which was introduced by Julius Caesar in 46 BC. This calendar used a system of leap years, where an extra day was added to the month of February every four years. This was to account for the fact that a solar year is slightly longer than 365 days. For a year to be a leap year under this system, it must be divisible by 4. Therefore, 1000, 1600, and 1776 were leap years according to the Julian Calendar, but 1492 was not since it is not divisible by 4. This calendar was replaced by the Gregorian Calendar in 1582, which uses a slightly modified leap year system. Under this system, a year is only a leap year if it is divisible by 4, but not if it is divisible by 100, unless it is also divisible by 400. Therefore, 1600 would still be a leap year under the Gregorian Calendar, but 1700, 1800, and 1900 would not be.

Step-by-step explanation:

By the Right Triangle Altitude Theorem, the two triangles formed by the altitude of a right triangle are similar to the original triangle and to each other.

In this case, triangle ABC is the original right triangle and CE is the altitude. Therefore, the similarity statement that is true is:

△ABC ∼ △AEC

This is because triangles ABC and AEC are both right triangles that share the angle at C, and the altitude CE creates two pairs of congruent angles (the right angles and the angle at A and E) and a pair of proportional sides (CE and AE are corresponding altitudes).

So, we can write the similarity statement as:

△ABC ~ △AEC

The volume of the solid generated when R is revolved around the x-axis is 20π/3 cubic units.

To find the volume of the solid generated when the region R is revolved around the x-axis, we can use the method of disks or washers.

First, let's find the points of intersection of the curves.

Setting the first two equations equal to each other, we have:

√(x^2/64) = √(x/8)

Squaring both sides, we get:

x^2/64 = x/8

Multiplying both sides by 64, we have:

x^2 = 8x

Rearranging, we get:

x^2 - 8x = 0

Factoring out x, we have:

x(x - 8) = 0

So, x = 0 and x = 8 are the points of intersection.

Now, let's integrate to find the volume of the solid.

We can split the region R into two parts: the part below y = 1 and the part between the curves y = √(x^2/64) and y = √(x/8).

For the part below y = 1, the radius of each disk is given by the corresponding x-value, and the height is 1. So the volume of this part is given by:

V1 = π * ∫[0,8] (1)^2 dx

Simplifying, we get:

V1 = π * ∫[0,8] dx

Integrating from 0 to 8, we have:

V1 = π * [x] evaluated from 0 to 8

V1 = π * (8 - 0)

V1 = 8π

For the part between the curves, the radius of each washer is given by the corresponding x-value, and the height is the difference between the curves: √(x^2/64) - √(x/8). So the volume of this part is given by:

V2 = π * ∫[0,8] [(√(x^2/64))^2 - (√(x/8))^2] dx

Simplifying, we get:

V2 = π * ∫[0,8] [(x^2/64) - (x/8)] dx

Integrating from 0 to 8, we have:

V2 = π * [(x^3/192) - (x^2/16)] evaluated from 0 to 8

V2 = π * [(8^3/192) - (8^2/16) - (0^3/192) + (0^2/16)]

V2 = π * [256/192 - 64/16]

V2 = π * [4/3 - 4]

V2 = -4π/3

The total volume of the solid is the sum of V1 and V2:

V = V1 + V2

V = 8π - 4π/3

V = (24 - 4)π/3

V = 20π/3

As a result, the solid created when R is rotated about the x-axis has a volume of 20/3 cubic units.

We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.

A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.

This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.

A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

The present value of the annuity is approximately `7032.08. The correct answer is option (d) None of these.

To find the present value of an annuity, we can use the formula:

PV = PMT * (1 - (1 + r)^(-n)) / r

Where PV is the present value, PMT is the periodic payment, r is the interest rate per period, and n is the number of periods.

In this case, the periodic payment is `200, the interest rate is 5% (or 0.05) converted quarterly, and the number of periods is 10 years, which equals 40 quarters.

Plugging in these values into the formula, we get:

PV = 200 * (1 - (1 + 0.05)^(-40)) / 0.05

Simplifying the equation, we find:

PV ≈ 200 * (1 - 0.12198) / 0.05

PV ≈ 200 * 0.87802 / 0.05

PV ≈ 35160.4 / 0.05

PV ≈ 7032.08

Therefore, the present value of the annuity is approximately `7032.08.

The length of the side BC is approximately 21.6 cm.

Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.

Given a right angled triangle ABC.

We have another smaller right angled triangle ABD.

∠BAD = 180° - (90° + 70°) = 20°

Similarly, ∠BAC = 180° - (90° + 40°) = 50°

Using the definition of tangent function,

tan 20° = BD / AB and tan 50° = BC / AB

Dividing,

tan 20 / tan 50 = BD / BC

Let BD be x.

Now, BC = BD + CD = x + 15

So the equation becomes,

tan 20 / tan 50 = x / (x + 15)

(x + 15) tan (20) = x tan (50)

x (tan 50 - tan 20) = 15 tan 20

Solving,

x = 6.595 cm

So, BC = BD + 15 = 21.595 ≈ 21.6 cm

Hence the length of BC is 21.6 cm.

Step-by-step explanation:

Answer:

Width = 17 feet, Length = 22 feet

Step-by-step explanation:

Let the width, w, be x

Therefore, length, L = x + 5

Perimeter = 78

p = 2(L+b)

78 = 2(x + x+5)

Adding the variables,

78 = 2( 2x + 5)

Dividing both sides by two,

39 = 2x + 5

Subtracting two from both sides,

34 = 2x

Dividing by two on both sides,

17 = x

Therefore, the width = x = 17 feet, and the length = x + 5 = 17 + 5 = 22 feet.
