The area of the base, B, equals  

✔ 21

cm2.

The volume of the prism is  

✔ 157 1/2

cm3.

Step-by-step explanation:

i took the test

The volume of prism for the given condition is 147 cm³.

A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

Here, Prism(Rectangle)

          Length(L) = 3.5 cm.

          Width(W) = 6 cm

         Height (H) = 7 cm

Volume = Area of Rectangle x Height

Volume of Prism: V = L x W x H

                             V = 3.5 X 6 X 7

                             V = 147 cm³

Thus, The volume of prism for the given condition is 147 cm³.

Answer:

there were 20 two point questions =

there were 30 five point questions

Step-by-step explanation:

Brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five-point questions. How many of each type of question were on the exam?

x + y = 50 eqn 1

2x + 5y = 160 eqn 2

this can be solved using simultaneous equation

multiply eqn 1 by 2

2x + 2y = 100 eqn 3

subtract eqn 3 from 2

3y = 60

y = 20

Substitute for y in eqn 1

x + 30 = 50

x = 20

Answer:

1 3/8

Step-by-step explanation:

We are to add 1/2 + 1/4 + 5/8

[tex]\frac{1}{2} + \frac{1}{4} + \frac{5}{8}[/tex]

[tex]\frac{4 + 2 + 5}{8}[/tex] = 11/8 = 1 3/8

Answer: 1 3/8

Step-by-step explanation:

Answer:

[tex](a)\ Area = 195\pi[/tex]

[tex](b)\ Volume = 700\pi[/tex]

Step-by-step explanation:

Given

[tex]h = 12[/tex]

[tex]d_1 = 10[/tex] --- lower diameter

[tex]d_2 = 20[/tex] --- upper diameter

Solving (a): The curved surface area

This is calculated as:

[tex]Area = \pi l(r_1 + r_2)[/tex]

Where

[tex]r_1 = 0.5 * d_1 = 0.5 * 10 = 5[/tex] --- lower radius

[tex]r_2 = 0.5 * d_2 = 0.5 * 20 = 10[/tex] --- upper radius

And

[tex]l = \sqrt{h^2 + (r_1 - r_2)^2[/tex] ---- l represents the slant height of the frustrum

[tex]l = \sqrt{12^2 + (5 - 10)^2[/tex]

[tex]l = \sqrt{12^2 + (-5)^2[/tex]

[tex]l = \sqrt{144 + 25[/tex]

[tex]l = \sqrt{169[/tex]

[tex]l = 13[/tex]

So, we have:

[tex]Area = \pi l(r_1 + r_2)[/tex]

[tex]Area = \pi * 13(5 + 10)[/tex]

[tex]Area = \pi * 13(15)[/tex]

[tex]Area = 195\pi[/tex]

Solving (b): The volume

This is calculated as:

[tex]Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))[/tex]

This gives:

[tex]Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))[/tex]

[tex]Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))[/tex]

[tex]Volume = \frac{1}{3}\pi * 12 * (175)[/tex]

[tex]Volume = \pi *4 * 175[/tex]

[tex]Volume = 700\pi[/tex]

Step-by-step explanation:

The exponential regression equation that fits the given data is [tex]y = 0.755 * e^{(0.071 * x)}[/tex]

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

Using the first and last data points (4,1) and (600,6), we can set up a system of two equations in two unknowns:

ln(y) = ln(a) + b * x1

ln(y') = ln(a) + b * x2

where x = 4, y = 1, x' = 600, and y' = 6. Taking the difference between the two equations, we get:

ln(y'/y) = b * (x' - x)

Solving for b, we get:

b = (1/(x' - x)) * ln(y'/y)

Substituting the values, we get:

b = (1/(600-4)) * ln(6/1)

b = 0.071

To find ln(a), we can use either of the two equations with the known values of ln(y) and b. Using the first equation, we get:

ln(y) = ln(a) + b * x

Substituting the values, we get:

ln(1) = ln(a) + 0.071 * 4

ln(a) = -0.279

Now that we have the values of ln(a) and b, we can convert them back to the exponential equation:

ln(y) = -0.279 + 0.071 * x

y = e^(-0.279) * e^(0.071 * x)

y = 0.755 * e^(0.071 * x)

This is the exponential regression equation that fits the given data.

Answer:

The number of boys who play tennis is 36.

Step-by-step explanation:

Let the number of boys who play tennis is x.

number of boys who play cricket = y

x = 3 y..... (1)  

12 boys plays both cricket and tennis.

According to the question,

x - 12 = y + 1 2

3 y - 12 = y + 12

2 y = 24

y = 12

So, the number of boys who plays tennis is x = 3 x 12 = 36.  

Answer:

True

Step-by-step explanation:

As a right triangle, it follows the Pathagorem Therom. All you have to do is multiply 15 x 15 = 225 and 20 x 20 = 400, then finally, you would do 25 x 25, which is the biggest number of all, and get 625. Since 225 + 400 = 625, this follows the Pathagorem Therom.

It is the distributive property.
