Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft

The value of z in the circle is 2.3 units

In the question, the following statements represents the given parameters

As a general rule, the diameter of a circle is the radius doubled

So, we have

2 * (z + 3.6) = 11 4/5

Express as decimal

2 * (z + 3.6) = 11.8

So, we have

z + 3.6 = 5.9

Evaluate the like terms

z = 2.3

Answer:

the last graph (D)

Answer:

x = 27 , ∠ EAF = 27°

Step-by-step explanation:

∠ GAF = 90° , then

∠ GAC + ∠ CAF = ∠ GAF , that is

x + 63 = 90 ( subtract 63 from both sides )

x = 27

∠ DAE = 90°

since CD is a straight angle of 180° , then

∠ CAE = 90° , so

∠ CAF + ∠ EAF = ∠ CAE , that is

63° + ∠ EAF = 90° ( subtract 63° from both sides )

∠ EAF = 27°

Thomas' installment payment that he pays in one fortnight is approximately k523.08.

To calculate Thomas' installment payment, we need to consider the principal amount (k10,000) and the interest rate (36%).

First, let's calculate the total amount to be repaid at the end of the year, including the interest. The interest is calculated as a percentage of the principal amount:

Interest = Principal × Interest Rate

= k10,000 × 0.36

= k3,600

The total amount to be repaid is the sum of the principal and the interest:

Total Amount = Principal + Interest

= k10,000 + k3,600

= k13,600

Now, we need to calculate the number of fortnights in a year. There are 52 weeks in a year, and since each fortnight consists of two weeks, we have:

Number of Fortnights = 52 weeks / 2

= 26 fortnights

To find the installment payment for each fortnight, we divide the total amount by the number of fortnights:

Installment Payment = Total Amount / Number of Fortnights

= k13,600 / 26

≈ k523.08

Therefore, Thomas' installment payment that he pays in one fortnight is approximately k523.08.

It's important to note that this calculation assumes equal installment payments over the course of the year. Different repayment terms or additional fees may affect the actual installment amount. It's always advisable to consult with the bank or financial institution for accurate information regarding loan repayment.

The pair of polygons that are similar to each other are all the pairs of polygons except the pair of rectangles.

Similar polygons are polygons that have corresponding side lengths that are proportional to each other, thus, they have the same shape by different sizes.

To determine if he given pairs of polygons are similar, check if their corresponding side lengths have the same ratio, that is, if they are proportional to each other.

For the trapezoids:

27/15 = 18/10 = 7.2/4 = 10.8/6 = 1.8

This means the trapezoids are similar.

For the rectangles:

18/10 ≠ 14/7

This means the rectangles are not similar.

For the right triangles:

32/24 = 24/18 = 40/30 = 1.33

This means the right triangles are similar polygons.

So also is the last pair of polygons similar to each other. Therefore, the only polygon that is not similar is the pair of rectangles.

Answer:

If only Jim purchased a cup of coffee, we will subtract its cost from the total;

9.50 - 1.00 = 8.50

Assuming that the two purchased nothing else for breakfast, and that the cost of an egg scramble was the same for both, let's call the price of the egg scramble x.

Since they both bought eggs, then 2x = 8.50

x = $4.25, the price for each egg scramble

The function is:

C(n) = 59 + 13n

where n is the number of people, and C(n) is the cost of a class party.

To determine the value of C(n) where n = 44, just replace this value of n into the previous formula, and simplify the expression, just as folow:

C(44) = 59 + 13(44)

C(44) = 59 + 572

C(44) = 631

Hence, the cost for 44 people is 631 dollars.

\((21a^6b^5) / (7a^3b)\) simplifies to \(3a^3b^4.\)

We can use the rules of exponents and simplify the terms with the same base.

Dividing the coefficients: 21 / 7 = 3.

For the variables, you subtract the exponents: \(a^6 / a^3 = a^(^6^-^3^) = a^3.\)

Similarly,\(b^5 / b = b^(5-1) = b^4\).

Putting it all together, the simplified expression is:

\(3a^3b^4.\)

The values of x for the tangent segments to the circles are: (25). x = 2 and (26). x = 4

A theorem of tangents to a circle states that if from one exterior point, two tangents are drawn to a circle then they have equal tangent segments.

(25). 2x - 1 = x + 1 {equal tangent segments}

2x - x = 1 + 1 {collect like terms}

x = 2

(26). 2x - 4 = x {equal tangent segments}

2x - x = 4 {collect like terms}

x = 4

Number of countries would west Virginia be expected to have is  18 countries

The number of campgrounds that North Dakota has = 465 campgrounds

The number of countries = 12 countries

The number of campgrounds that West Virginia has = 711 campgrounds

Given that the North Dakota was proportional to West Virginia in the number of campgrounds to counties.

The proportion will be

465 / 12 = 711 / x

Divide the terms

38.75 = 711 / x

x = 711 / 38.75

The answer is 3/10.

Im sure.

Answer:

The minimum score required for an A grade is 88.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

\(\mu = 77.5, \sigma = 8.6\)

Find the minimum score required for an A grade.

This score is the 100 - 12 = 88th percentile, which is X when Z has a pvalue of 0.88. So X when Z = 1.175.

\(Z = \frac{X - \mu}{\sigma}\)

\(1.175 = \frac{X - 77.5}{8.6}\)

\(X - 77.5 = 8.6*1.175\)

\(X = 87.61\)

Rounding to the nearest whole number:

The minimum score required for an A grade is 88.

The  average rate of change between the intervals x = -2 and x = 4 of the function f(x) = 4x³ - 15x + 3 is; 33

The average rate of change is defined as a measure of how much the function changed per unit, on average, over a given interval.

We are given the function;

f(x) = 4x³ - 15x + 3

Between the intervals x = -2 and x =4, the average rate of change can be gotten from;

[f(4) - f(-2)]/(4 - (-2)

f(4) = 4(4)³ - 15(4) + 3

f(4) = 199

f(-2) = 4(-2)³ - 15(-2) + 3

f(-2) = -32 + 30 + 3

f(-2) = 1

Average rate of change = (199 - 1)/(4 - (-2)

The cards are: 2 3 4 56.

There are five cards in all. There are two even numbers (2, 4) and three odd numbers (3-5).

Out of a total of 5 possible outcomes, 3 favourable outcomes (3, 5, 6) can be used to determine the likelihood of selecting an odd number first.

Picking an odd number first has a 3/5 chance of happening.

There are now 4 cards left, 2 of which have odd numbers (3, 5) and 2 of which have even numbers (2, 4), after selecting an odd number.

Out of a total of 4 possible outcomes, we have 2 favourable outcomes (3, 5) that we may use to determine the chance of selecting an odd number second.

Choosing an odd number second has a 2/4 chance of happening.

Since the two events are separate, we may add their probabilities to determine the likelihood that both will occur:

P(Odd and Odd) = P(Odd first) * P(Odd second)

= (3/5) * (2/4)

= 6/20

= 0.3

We multiply the chance by 100 to express it as a percentage:
