Answer: [tex]3\dfrac{1}{8}\ \text{cups}[/tex]

Step-by-step explanation:

Given

Yoshi need [tex]1\frac{1}{4}[/tex] cups of blueberries to make 1 batch of muffins

convert mixed fraction to fraction

[tex]\Rightarrow 1\dfrac{1}{4}=\dfrac{5}{4}[/tex]

i.e. [tex]\frac{5}{4}[/tex] cups are required for 1 batch of muffins

for [tex]2\frac{1}{2}[/tex] batch or [tex]\frac{5}{2}[/tex] batch it is given by

[tex]\Rightarrow \dfrac{5}{2}\times \dfrac{5}{4}\\\\\Rightarrow \dfrac{25}{8}=3\dfrac{1}{8}\ \text{cups}[/tex]

Answer:

Since weight is directly dependent on the acceleration of gravity, things on the Moon will weigh only 16.6% (≈ 1/6) of their weight on Earth.

Step-by-step explanation:

Being that the moon has a gravitational force of 1.622m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon.

Answer:

50°  and  130°

Step-by-step explanation:

Linear pair of angles are supplementary, which means their sum is 180

x + 10 + 3x + 10 = 180

4x + 20 = 180

4x = 160

x = 40

x + 10 = 40 + 10 = 50°

3x + 10 = 3(40) + 10 = 120 + 10 = 130°

Answer:

$45

Step-by-step explanation:

Answer:

50 grams

Step-by-step explanation:

36 grams = 72%

→ Find 1% by dividing both sides by 72

0.5 grams = 1%

→ Times both sides by 100 to find 100%

50 grams = 100%

Answer:

83 1/4 sq ft

Step-by-step explanation:

let x = length or width of two identical unknown sides

2(9) + 2x = 36 1/2

18 + 2x = 36 1/2

2x = 18 1/2

x = 37/2 ÷ 2 = 37/4 or 9 1/4

therefore, multiply 9 by 9 1/4

Area is:  9/1 x 37/4 = 333/4 = 83 1/4

Answer:

A

Step-by-step explanation:

1A). 1² + 4²

= 1 + 16

= √17

B). 1² + 16²

= 1 + 256

= √256

= 16

C). 2² + 8²

4 + 64

= 68

= 2√16

D). 2² + 15²

= 4 + 225

= √299

Answer:

*read explanation for both questions*

Step-by-step explanation:

So the first one asks ”the first number in a pattern is 6, the pattern follows the rule ’multiply by 4’ “

The question has the answer to it, so each number would be multiplied by 4. So we have the first one which is 6, next we multiply 6 x 4 = 24. Then we multiply 24 x 4 = 96. and finally you multiply 96 x 4 = 384.

That’s the pattern fo the first one

The second one asks “The shapes have been sorted into two groups. explain what attribute was used to sort the shapes.”

When we’re looking for attributes, look for what they have in common. For me, I see that Group 1 has the smaller versions of the same shapes in Group 2. So that could be the attribute the question is asking for.

Answer:

Step-by-step explanation:

SA for a sphere = 4pi(radius)^2

V for a sphere = 4/3pi(radius)^3

A golf ball is a sphere and its radiusm is 1.68/2 = 0.84 in.

So SA = 4pi(0.84)^2 = 8.87 in^2

V = 4/3pi(0.84)^3 = 2.48 in^3

Answer:

point d

ray cd

segment cd

Step-by-step explanation:

Answer:

320 sq in

Step-by-step explanation:

SA(rect prism) = 2(lw)+2(wh)+2(lh)

= 2(12·7)+2(7·4)+2(12·4)

= 2(84)+2(28)+2(48)

= 168+56+96

= 320

Step-by-step explanation:

[tex]3 : 12 \equiv \frac{3}{12} \equiv 1 : 4[/tex]

[tex] \frac{3}{5} \equiv3 : 5[/tex]

[tex]108 : 9 \equiv \frac{108}{9} \equiv12 : 1[/tex]
