Answer:

a. 32

b. 32

Step-by-step explanation:

a. 12 + 4y

They gave us the value of "y" which is "5", and substitute that into the expression.

12 + 4y

12 + 4(5)

12 + 20

b. 4 (y + 3)

They gave us the value of "y" which is "5", and substitute that into the expression.

4 ( y + 3 )

4 ( 5 + 3)

Distributive property (multiply what is in the parenthesis by what is out of it (4))

4 * 5 + 4 * 3

20 + 12

Hope this helped!

Find the length of the major arc in RED. Round your answers to the nearest tenth.

scoray [572]

Answer:

52.4

Step-by-step explanation:

Arc length = 2πr(θ/360)

r = 10

θ = 300°

Arc length = 2π(10)(300/360) = 20π(0.8333) = 16.666π ≈ 52.36

Complete Question:

Katya creates handmade sets of dolls, which is sold to craft and souvenir stores. The first set of dolls has a middle diameter of 7cm and a height of 12cm.

Katya made another set of dolls. In the new set, the largest doll has a diameter of 8.75 cm and a height of 15.6 cm. Is this a dilation of the first set of dolls?

Answer:

The new set is not a dilation of the first set

Step-by-step explanation:

Given

First Set:

$Height = 12cm$

$Diameter = 7cm$

New Set:

$Height = 15.6cm$

$Diameter = 8.75cm$

Required

Determine if the new set is a dilation of the second

To do this, we pass through the following steps:

1. Divide the height of the first set by the new set

2. Divide the diameter of the first set by the new set

3. Result in (1) and (2) must be equal if the new set is a dilation of the first set

Following the steps above:

(1)

$Height\ Ratio = \frac{H_2}{H_1}$

$Height\ Ratio = \frac{15.6}{12}$

$Height\ Ratio = 1.3$

(2)

$Diameter\ Ratio = \frac{D_2}{D_1}$

$Diameter\ Ratio = \frac{8.75}{7}$

$Diameter\ Ratio = 1.25$

(3) Make comparison

The ratio in (1) does not equal the ratio in (2)

i.e.

$1.3 \neq 1.25$

Hence, the new set is not a dilation of the first set

5y>3x+4 A.x=1,y=1 B.x=1,y=2 C.x=2,y=1 D.x=4,y=3

ziro4ka [17]

5(2)>3(1)+4

10 > 7. Is True because 10 is greather than 7. All needed to do is evaluate the x and y variables for each possibility. A, B, C D. And see if is a logical answer.

Any other combination gives you a false statement.

WILL GIVE BRAINLIEST TO BEST RESPONSE!

Monica [59]

You are given the X value, replace x with 2 in the first equation to solve for y:

y=2x +3

y = 2(2) +3

y = 4+3

y = 7

Now replace y with 7 and x iwth 2 in the second equation and solve for k:

y = -x +k

7 = -2 +k

Add 2 to both sides:

9 = k

so k = 9

The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.

K = 9

1. BOTANICAL GARDENS One of the displays at a botanical garden is an herb garden planted in the shape of a square. The square me

bija089 [108]

The pathway is 8.46 yards.

<h3>How to find the length of the pathway?</h3>

To find the length of the pathway, it is required to find how long is the diagonal line from one corner of the herb garden to the opposite corner. As shown in the image attached.

The general formula for this is:

d = a√2 or diagonal = side√2

Let's apply this formula:

d= 6 √2
d= 6 x 1.41
d= 8.46 yards
