Write a formula for rrr in terms of \thetaθtheta for the following figure.

Answer:

Top, a through d:

A) 23/8

B) 29/6

C) 23/3

D) 16/5

Step-by-step explanation:

To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)

Answer:

A. 2 and 3

Step-by-step explanation:

The square root of 7 is 2.7 which makes it between 2 and 3.

Answer:

A

Step-by-step explanation:

because the square root of 4 is 2

and the square root of 9 is 3

since 7 is in between 4 and 9 the square root is in between 2 and 3

Answer:

16m

Step-by-step explanation:

Separate the rectangle from the triangle. The area of the rectange is 10m. We know this because l x w (2m x 5m).

Now for the triangle;

The area of a triangle is b x h / 2. We take the full height of the figure and subtract 5 from it giving us 3 which is our height for the triangle. We then see that 2m is on the bottom and we add that 2m to the two separate 1m giving us 4m in total.

Now that we have the base and height of the triangle we plug in giving us 6m. Finally we add both the areas; 10m + 6m = 16m.

Answer:

40 sq feet

Step-by-step explanation:

(im bad at explaining)

1 x 2 = 2 sq ft

3 x 2 = 6 sq ft

4 x 12 = 48 sq ft

2 sq ft + 6 + sq ft = 8 sq ft

48 - 8 = 40

The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².

Area of a rectangle = lenght × width.

The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)

The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)

The amount of square feet of outdoor carpet needed = 48 - (6 + 2)

The amount of square feet of outdoor carpet needed = 40 ft²

Answer:

7  

Step-by-step explanation:

Given:

The table represents a proportional relationship.

To find:

The equation of the function.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]     ...(i)

where, k is the constant of proportionality.

From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).

Putting x=2 and y=1 in (i), we get

[tex]1=k(2)[/tex]

[tex]\dfrac{1}{2}=k[/tex]

Putting [tex]k=\dfrac{1}{2}[/tex], we get

[tex]y=\dfrac{1}{2}x[/tex]

Therefore, the correct option is A.

Answer:

m∠A = 106°

Step-by-step explanation:

All three sides of the triangle are given in the question.

To find the measure of included angle A between two sides we will apply cosine formula,

BC²= AB² + AC² - 2(AB)(AC)cosA

(13)² = (10)² + (6)² - 2(10)(6)cosA

169 = 100 + 36 - 120cosA

cosA = [tex]\frac{-169+136}{120}[/tex]

cosA = -0.275

A = [tex]\text{cos}^{-1}(-0.275)[/tex]

A = 105.96°

A ≈ 106°

Therefore, m∠A = 106° will be the answer.

b: 18.84 in.

use the formula 2 x radius x pi (3.14).

Answer:

eggplant cost more/pound.

Step-by-step explanation:

ep= 7$/pound

br= 5.6$/pound

     That the Egg Plant costs more.

My reasoning for this is because if you do 21 divided by 3 it equals 7 which means each pound of Egg Plant is $7. But 28 divided by 5 is 5.60. Which means, Beetroot is $5.60 per pound! So, beetroot is less than the Egg Plant!

Answer:

[tex]Area = 210m^2[/tex]

Step-by-step explanation:

The attached shape is a trapezium and the given dimensions are:

[tex]B_1 = 10m[/tex] -- Base 1

[tex]B_2 = 20m[/tex] --- Base 2

[tex]H = 14m[/tex] --- Height

Required

Calculate the area

The area is calculated as thus:

[tex]Area = \frac{1}{2}(B_1 + B_2) * H[/tex]

[tex]Area = \frac{1}{2}(10m + 20m) * 14m[/tex]

[tex]Area = \frac{1}{2}(30m) * 14m[/tex]

[tex]Area = 15m * 14m[/tex]

[tex]Area = 210m^2[/tex]

Step-by-step explanation:

Answer:

-a > -b

Step-by-step explanation:

On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).

The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.

If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.

So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.

Example: let a = 3 and b =5.  

It is true that 3 < 5.

But it is NOT true that -3 < -5. It's the other way around!

-5 < -3

So, if a < b, then -a > -b.

Answer:

Z = -0.675.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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.

What z-score value separates the lowest 25% of the scores from the rest of the distribution

This is Z which has a pvalue of 0.75, so Z = -0.675.
