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:

10.5 cm

Step-by-step explanation:

12÷9= 1.3 (1dp)

14÷(12÷9)= 10.5cm

Answer:

y = 10.5 cm

x = 80 degree

Step-by-step explanation:

Our approach is find measures first and y is our missing measure.

To find y

PQRS : ABCD   is in ratio the same as CD : RS

We need to work out CD : RS to find measures of  AD : SP

To find ratio we look at side measures first

CD : RS  = 12 : 9

12/9 = 1.333333

So that AD : SP   = 14 : ?

14 / 1.333333 = 10.50000

AD : SP =  14 : 10.5

y = 10.5 cm

To find x

We are given opposite angles and know with quadrilaterals they both share same opposite diagonal length ratios and share same opposite angles.

Where two angles are always in pairs given 100 degree can be multiplied by 2 and use the equation.

360 - (100 x 2) / 2  =  (360 - 200) / 2 = 160/2 = 80 degree

x = 80 degree

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:

5. D  

6. 80°  

7. 100°

Step-by-step explanation:

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:

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

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
