Step-by-step explanation:

no reason for an "emergency". we just have to do several things for this one problem, but all of these things are pretty basic.

I understand the garden is a rectangle.

the area is

length × width = 1787.5 m²

length = 2×width - 10

the first step is to solve these 2 equations to get length and width.

the second step is to calculate from there the perimeter.

and the third step is then to divide this perimeter length into pieces of 15 m and determine the remainder, so that we can calculate the price for the fence.

1.

we use the second equation in the first and get

(2×width - 10)×width = 1787.5

2×width² - 10×width = 1787.5

width² - 5×width = 893.75

width² - 5×width - 893.75 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

width = x

a = 1

b = -5

c = -893.75

width = (5 ± sqrt(25 - 4×1×-893.75))/(2×1) =

= (5 ± sqrt(25 + 3575))/2 = (5 ± sqrt(3600))/2 =

= (5 ± 60)/2

width1 = (5 + 60)/2 = 65/2 = 32.5 m

width2 = (5 - 60)/2 = -55/2 = -27.5 m

but a negative solution is not applicable to a length calculation, so, width = 32.5 m is our solution.

length = 2×width - 10 = 2×32.5 - 10 = 65 - 10 = 55 m

2.

the perimeter of the garden is then

2×length + 2×width = 2×55 + 2×32.5 = 110 + 65 = 175 m

3.

the cheapest price for the fence is to buy as many bulk order 15m rolls as possible.

175/15 = 11, remainder 10

so, the first approach is to buy 11 bulk order rolls and 10 m individual fence wire.

just a quick check, if buying a 12th bulk order roll would be cheaper than 10 individual meters :

12.5 × 10 = RM125

this is cheaper than RM150 for a whole bulk order roll.

so, we stick with our first approach.

the lowest cost for the fence is

11×150 + 10×12.5 = 1650 + 125 = RM1775

Answer:

180= 2x + 37 + 67 + 90

2x = 180 - 37 - 67 - 90

2x = -14

X= -7

A = -7 + 37 = 30

-7 + 67 = 60

30 + 60 + 90 = 180°

Answer:

sorry I'm not the best with math and sorry if I just waisted your time... :)

The measurement of length, L = 37.11 meters, has four significant figures.

To determine the number of significant figures in a measurement, we consider the digits that are known with certainty and the first uncertain or estimated digit. In the given measurement, 37.11 meters, all the digits (3, 7, 1, and 1) are known with certainty, and there is no estimated digit. Therefore, we count all the digits as significant.

In the measurement L = 37.11 meters, all the digits are considered significant. Leading zeros that serve only as placeholders (such as 0.012) are not significant, but in this case, there are no leading or trailing zeros. The presence of a decimal point after the ones digit indicates that the measurement is known to a specific decimal place.

As a result, the measurement L = 37.11 meters has four significant figures. Each digit contributes to the precision of the measurement and reflects the level of certainty in the value.

Answer: Pythagorean theorem

Step-by-step explanation: cannot see the rectangle but I assume it’s the Pythagorean theorem

The sum of the area of all the rectangles will be 2a + 3a + 4a.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Given:

The large rectangle has length a and width (2 + 3+ 4)

Area of the rectangle = L×W square units

A = a  (2 + 3+ 4)

A = 2a + 3a + 4a

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

The fruit stand owner can make 23 complete orange baskets.

Division is a mathematical operation which involves the sharing of an amount into equal-sized groups. For example, “12 divided by 4” means “12 shared into 4 equal groups”, which would be 3.

To determine the number of complete orange baskets that can be made, divide the total number of oranges by the number of oranges per basket.

Total oranges: 185

Oranges per basket: 8

Divide 185 by 8 to find the number of complete baskets:

The statements for the function f( x) = 3x ²- 5 are

f( 5)< 1( false)

f( 0) = 1( false)

Statements for the function f(x) = 3x ²- 5

To find the true or false statement we have to substitute the value for x

First, x= 3

f(x) = 3x ²- 5

f(3)= 3( 5)²- 5

f(3) = 75- 5

f(3)= 70.

Thus, the statement" f( 5)< 1" is false.

Now, at x =0

f(x) = 3x ²- 5

f(0) = 3( 0)²- 5

f(0)= 0- 5

f(0)= -5.

Thus, the statement" f( 0) = 1" is false.

A t-test is a statistical method that determines whether two groups of observations are significantly different from one another. When comparing the means of two populations, the t-test is commonly used. The t-test is used to determine whether two groups' means are significantly different when the samples are drawn from normally distributed populations with equal variances.

The t-test is a powerful tool for determining whether a sample is significantly different from a population or whether two samples are significantly different from one another.

the critical value to test the given claim is ±1.96. If the test statistic falls outside this range, we would reject the null hypothesis in favor of the alternative hypothesis.

To determine the critical value for testing the given claim, we need to perform a hypothesis test. The claim is that the percentage of adults who paid with an interest-bearing credit card during Black Friday has increased.

We will use a two-proportion z-test to compare the proportion in the survey with the known population proportion. The null hypothesis (H₀) is that the percentage has not increased, and the alternative hypothesis (H₁) is that it has increased.

Given that the significance level is 0.05, we can find the critical value from the standard normal distribution table. For a two-tailed test at α = 0.05, the critical z-value is approximately ±1.96.

Therefore, the critical value to test the given claim is ±1.96. If the test statistic falls outside this range, we would reject the null hypothesis in favor of the alternative hypothesis.

The weight of 70 vitamins is 61.25 grams and the total weight of the bottle with vitamins is approximately 1403.14 grams respectively.

a) To find the weight of 70 vitamins, multiply the weight of one vitamin by the total number of vitamins: 70 * (7/8) grams.
b) To find the total weight, add the weight of the empty bottle to the weight of the 70 vitamins.

a) 70 vitamins * (7/8) grams = 490/8 grams = 61.25 grams (weight of 70 vitamins)
b) Empty bottle weight = 12077/9 grams ≈ 1341.89 grams
Total weight = weight of empty bottle + weight of 70 vitamins = 1341.89 grams + 61.25 grams ≈ 1403.14 grams

Thus, the weight of 70 vitamins is 61.25 grams and the total weight of the bottle with vitamins is approximately 1403.14 grams respectively.
