Answer 1

Answer: A. 1 = 3/3 = 4/4 = 52/52 = x/x

B. 5 = 10/2 = 15/3 = 7.5/1.5 = 120/24 = 5a/a

All the ratios must equal each other

What fraction of a pound is 25 pence

Answers

There are 100 pence in a Pound. So we have to divide 25 pence over this pound, or over 100 pence: 25/100 is 1/4, so 25 Pence is one forth of a Pound (or 25 % in percentages):

# 27 a rectangular piece of cloth had an area of 1/12 square yard

Answers

1/9
becuase 27-1/12= 1/9

1/12 ÷ 2

2 = 2/1

1/12 ÷ 2/1 = 1/12 X 1/2
1 X 1 = 1
12 X 2 = 24

The answer is 1/24 yard

Monte performs an experiment using 2 identical graduated cylinders with a radius of 2 cm. The volume of the liquid in the first graduated cylinder is 188.4 cm3. The volume of the liquid in the second graduated cylinder is 314 cm3.What is the difference in the height of the liquid in the two cylinders?

Use 3.14 to approximate pi.

Answers

Answer:

The difference of height is 10 cm

Step-by-step explanation:

Monte performs an experiment using 2 identical graduated cylinders with a radius of 2 cm.

The volume of the liquid in the first graduated cylinder is 188.4 cm³

The volume of the liquid in the second graduated cylinder is 314 cm³

Let height of first graduated cylinder be h₁ and radius (r) = 2 cm

Let height of second graduated cylinder be h₂ and radius (r) = 2 cm

Formula:

$\text{Volume of cylinder}=\pi r^2h$

$\text{Volume of 1st cylinder}=\pi\cdot 2^2h_1$

$188.4=3.14\cdot 2^2\cdot h_1$

$h_1=15$ cm

$\text{Volume of 2nd cylinder}=\pi\cdot 2^2h_2$

$314=3.14\cdot 2^2\cdot h_2$

$h_2=25$ cm

The difference in the height of the liquid in two cylinder,

$\Rightarrow h_2-h_1$

$\Rightarrow 25-15$

$\Rightarrow 10$ cm

Hence, The difference of height is 10 cm

Volume of a cylinder of radius r, height h : $V=\pi*r^2*h$

hence the height of the liquid in the first cylinder is $h1=(188.4)/(2^2\pi)=15$ cm, and in the second cylinder $h2=(314)/(2^2\pi)=25$ cm

Hence the difference is h2-h1=25-15=10 cm

A company shipped 48 boxes of canned dog food each box contains 24 cans how many cans of food did the company ship in all

Answers

To do this you have to multiply 48 by 24. This will give you 1,152. They shipped 1,152 cans of food in all.

You would have to multiply 48 * 24 and the answer is 1152
