You need to figure out the cubic volume of each part separately.

For the big portion, multiply 6 x 4 x 12

For the smaller portion, multiply 8 x 4 x 4

-5 = 7 + 3r

Answers

So,

-5 = 7 + 3r
(subtract 7 from both sides)
-12 = 3r
(divide both sides by 3)
-4 = r

A bread recipe calls for 3/4 cups of flour and 1/5 cup of sugar. based on the recipe, what is the amount of sugar that should be used with 1 cup of flour?A. 3/20 CUP
B. 4/15 CUP
C. 3 3/4 CUPS
D. 6 2/3 CUPS

Answers

The solution is, 4/15 is the amount of sugar that should be used with 1 cup of flour.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Given

A bread recipe requires 3/4 cup of flour

and 1/5 cup of sugar

i.e. ratio of flour and sugar is 3/4 / 1/5

which will remain same for each time we make bread

When 1 cup of flour is used then amount of sugar is

Suppose x cup of sugar is required so equating the ratio of flour to sugar

to get one cup we can multiply by the reciprocal. (the oppisite of the current fraction) 3/4*4/3 = 1.

so then we need to raise the sugar by the same variable

1/5 * 4/3. cross multiplication gives us

1*4=4

3*5=15

x = 4/15

Hence, The solution is, 4/15 is the amount of sugar that should be used with 1 cup of flour.

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

andre has 4 times as many model cars as Peter , and Peter has one-third as many model cars as jade . andre has 36 model cars . a: write and solve an equation to find how many model cars Peter has . b: using your answer fir part a ,write and solve an equation to find how many model cars jade has.

Answers

Answer:

a: 9

b: 27

Step-by-step explanation:

Let's define  

P = amount of model cars that Peter has

J =amount of model cars that Jade has

A = amount of model cars that Andre has

a:  We need to find out how many model cars does Peter have, i.e. we need to find out P.

We know that Andre has 36 model cars and he has 4 times as many model cars as Peter. If we write that as an equation, we have

A = 4*P = 36

Now we just have to divide by 4:

4*P/4 = 36/4

P = 9

Peter has 9 model cars.

b: Now we need to find out how many model cars does Jade have, i.e. we need to find out J.

We will resolve it as in part a:

Peter has 9 model cars and he has one-third as many model cars as Jade, that is

P = 1/3*J = 9

We multiply by 3 and we have:

1/3*J*3 = 9*3

J = 27

Jade has 27 model cars.
p = how many cars Peter has
j = how many cars Jade has
a = how many cars Andre has
p x 4 = how many cars Andre has (36 model cars)
>>>TO FIND HOW MANY MODEL CARS PETER HAS:
p x 4 = 36
36 / 4 = 9
your equation to find how many model cars Peter has is:
36 / 4 = 9
So, Peter has 9 model cars.
>>>TO FIND HOW MANY MODEL CARS JADE HAS:
36 / 4 = how many cars Peter has (9)
Now, you are given the info that Jade has THREE TIMES (3x) as many cars as Peter already.
So, your equation for this one is:
9 x 3 = 27
So Jade has 27 model cars.

---- Jade has 27 model cars.
---- Andre has 36 model cars.
---- Peter has 9 model cars.

equation for a. 36 / 4 = p
equation for b. 9 x 3 = j
