Answer:

26 quarts

Step-by-step explanation:

[tex]6\frac{1}{2} = \frac{13}{2}\\\\3\frac{1}{2} = \frac{7}{2}[/tex]

Quarts                 Cake

  [tex]\frac{13}{2}[/tex]                        [tex]\frac{7}{2}[/tex]

   x                        14

find x.

Cross multiply to find x.

[tex]x \times \frac{7}{2} = 14\times \frac{13}{2}\\\\\frac{7x}{2} = 7 \times 13\\\\7x = 7 \times 13 \times 2\\\\x = \frac{7 \times 13 \times 2}{7} = 26[/tex]

So you need 26 quarts for 14 cakes

Answer:

60

Step-by-step explanation:

Answer:

60º

Step-by-step explanation:

Since the angle is a right angle, which is 90º, all you have to do to find angle s is subtract 30 from 90, which gives you 60

Answer:

Total angles on a straight Line is 180°

SO

x + 12 + 100 + x = 180

2x + 112=180

2x= 180 - 112

2x =68

x=34°

Have a great day!!!

Answer: A

Step-by-step explanation:

A linear function is described as:

https://tex.z-dn.net/?f=f(x)%20%3D%20ax%20%2B%20b

When the value of x = 0, then you're left with

https://tex.z-dn.net/?f=f(x)%20%3D%20b

In this question, the speed of sound is the linear function while the temperature is the independent variable. When T = 0, you're left with

https://tex.z-dn.net/?f=S(0)%20%3D%20331.4

Which means the speed of sound in air when temperature is 0°C is 331.4m/s.

Answer:

Calculator is 2, Math book is 3, Ruler is 5, and Pencil is 4

Soultion #1 = 14

Solution #2 = -8

Step-by-step explanation:

2 x 3 = 6

3 + 5 = 8

4 x 5 = 20

2 + 4 = 6

Soultion #1 = 2 + 5 + 4 + 3 = x

7 + 4 + 3 = x

11 + 3 = x

11 + 3 = 14

Solution #2 = 3 - 4 - 2 - 5 = x

-1 - 2 - 5 = x

- 1 + (-2) - 5 = x

-3 - 5 = x

-3 - 5 = -8

Answer:

Amy

Explanation:

Because add all of the numbers and divide by 7.

The measure of center I would use for Amy is 6 because it is higher than half of the numbers and lower than half of the numbers.What I would use for Chelsea is 7 because of the same reason.

Answer:

Thus, the ratio of the central angles is 4 : 9.

Step-by-step explanation:

Area, A = 12 π square units

radius, R = 6 units

radius, r = 4 units

Area of sector is given by

[tex]A=\frac{\theta }{360}\times \pi r^{2}[/tex]

For first sector

[tex]12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}[/tex]

For second sector

[tex]12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}[/tex]

So, the ratio is

[tex]\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9[/tex]

Answer:

4 : 9

Step-by-step explanation:

Given:

Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.

Find ratio of central angles.

Solution:

Let A = central angle

Area of a sector = pi r^2 (A/360)

Since both sectors have the same area,

pi r1^2 (A1/360) = pi r2^2 (A2/360)

simplifying

A1 r1^2 = A2 r2^2

Therefore

A1 : A2  = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9

Step-by-step explanation:

it the red one which has the number 1

ans /4 actually can u give five more sentences

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Answer:

Step-by-step explanation:

Step-by-step explanation:

I think sorry if im wrong

answer 1. is 35h+15m

1) False

Adjacent angles must share a common side/ray.

2) B and D

Adjacent angles are those that are directly next to each other and share a common side.

3) C

Angles 1 and 2 are congruent. Angles 3 and 4 are congruent. Both of these pairs have angles that are opposite each other.

4) B

Angles 1 and 2 add up to 180. Angles 3 and 4 add up to 180. Both of these pairs of angles are supplementary.

5) A

These angles are directly next to each other and share a common side.
