A And B Are Two Cylinders That Are Mathematically Similar.The Area Of The Cross-sectionof Cylinder A

Answers

Answer 1

Answer:

Volume is 718 cm^3

Step-by-step explanation:

We need to get the radius of cylinder A

From the base area,

we have that;

A = pi * r^2

18 = 3.142 * r^2

r^2 = 18/3.142

r^2 = 5.73

r= √5.73

r = 2.39

If two shapes are similar, we have the ratio of their corresponding sides equal;

Thus;

2.39/5 = x/10

x = (10 * 2.39)/5

x = 4.78 cm

To get the volume, we use the formula

V = pi * r^2 * h

V = 3.142 * 4.78^2 * 10

V = 717.8 cm^3

This is approximately 718 cm^3

Greta has two pet lizards draco and lizzy for every 11 crickets Greta feeds draco she always feeds lizzy 8 crickets last week Greta fed draco 77 crickets

Answers

greta fed lizzy 56 crickets

Answer:

She feeds Lizzy 56 crickets when she feeds Draco 77.

Step-by-step explanation:

Lets put it as an equality:

[tex]\frac{11}{8}[/tex]  = [tex]\frac{77}{x}[/tex]

We want to solve for x. We can do so by finding how much larger the second fraction is than the first. In this case, 77 is 7 times larger than 11 (77/11=7), so we know that x must also be 7 times larger than 8 (because the fractions are proportional).

Since x is 7 times larger than 8, we can use 7 times 8 to find the value.

7 times 8 is 56

56 crickets for Lizzy!

Find the slope of the linear function. 12x=-10+2y

Answers

Answer: The slope is 6

The attachment shows the graph of this equation.

Step-by-step explanation: It will help to put this equation in order.

We can get standard form by subtracting 2y from both sides

12x=-10+2y becomes  12x - 2y = -10

For slope-intercept form, y = mx + b,  m is the slope, b is the y-intercept

we need to isolate y on the left.  Subtract 12x from both sides.

12x - 2y = -10 becomes  -2y = -12x - 10

Then divide both sides by -2 to end up with

y = 6x + 5

The slope is m, the coefficient of the x,

That is 6 in this equation.

Work out h, the height of the triangular cross section.

Hem

Answers

Answer:

1.25cm

Step-by-step explanation:

Complete question:

The prism has a volume of 35 cm cubed  workout h, the height of the triangular cross section

length=7cm

width = 4cm

The volume of the prism is expressed as;

Volume = Base Area * Height

Given

Volume of the prism = 35cm^3

Base Area = length * width

Base Area =  7cm * 4cm

Base Area = 28cm^2

Substitute the given values into the formula

35 = 28* Height

Cross multiply

35 = 28 * Height

35 = 28 Height

Height = 35/28

Height = 1.25cm

Hence the height of the triangular cross section is 1.25cm

its c cause its like method or principle of reasoning

We defined an argument as a reasoned or thoughtful process. The correct option is A.

What is an argument?

An argument is a statement or set of claims known as premises that are designed to assess the degree of truth or acceptability of another statement known as the conclusion. Arguments may be analyzed from three different perspectives: logical, dialectical, and rhetorical.

Since the act or process of arguing, reasoning, or discussing is known as an argument. Therefore, we defined an argument as a reasoned or thoughtful process.

An argument is made up of three parts: the conclusion, the premises, and the assumptions. 

THE Conclusion

The conclusion (or theses) is the point of the argument's major idea—what the author is attempting to show.

THE LOCATION

The premises are the reasoning or evidence provided by the author to justify the conclusion.

THE ASSURANCES

The assumptions support the conclusion, but unlike the premises, they are unsaid and so invisible.

They connect the premises and conclusions.

Answers

Answer:

count the number of triangles and then the total number of shapes so if there are 7 triangles and 21 shapes total the answer would be 7-21

Step-by-step explanation:

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The total number of shapes is 9. And the number of triangles is 4.

Then the ratio of the triangles to the total number of shapes will be given as,

Ratio = 4 / 9

The ratio of the triangles to the total number of shapes will be 4/9. Then the correct option is D.
