Easy question and easy math

Answer:

Q1 2. Q2 3.

Step-by-step explanation:

to solve a system of equations, you would usually have to use either elimination or substitution. however, in both of these problems, Y is given directly so that's unnecessary

for these, all you have to do is plug in y and then solve for x, where x is then the first number in the ordered pair and y is the second number.

Q1 48/-6 = -8, so the answer is (-6,-8)

Q2 10/2=5, so the answer is (5, -1)

Answer:

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]

Step-by-step explanation:

Given

[tex]V = \frac{4}{3}\pi r^3[/tex]

Required

Find V when

[tex]r = \frac{3}{2}x^3y^{-2[/tex]

Substitute [tex]\frac{3}{2}x^3y^{-2[/tex] for r in [tex]V = \frac{4}{3}\pi r^3[/tex]

[tex]V = \frac{4}{3}\pi * (\frac{3}{2}x^3y^{-2})^3[/tex]

Open bracket

[tex]V = \frac{4}{3}\pi * \frac{3}{2}^3 * x^{3*3}y^{-2*3}[/tex]

[tex]V = \frac{4}{3}\pi * \frac{27}{8} * x^{9}y^{-6}[/tex]

Simplify the fractions

[tex]V = \pi * \frac{9}{2} * x^{9}y^{-6}[/tex]

Let

[tex]\pi = \frac{22}{7}[/tex]

So:

[tex]V = \frac{22}{7} * \frac{9}{2} * x^{9}y^{-6}[/tex]

[tex]V = \frac{11}{7} * \frac{9}{1} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]

Answer:

44 in^2

Step-by-step explanation:

The surface area is 2 circles and one rectangular shape side, the area for the circle is A = pi*r^2 = 1^2*pi, and side area is circumference of the circle times height, so A side = pi*D*height = 2pi*6 =12pi.

So total surface area = 2pi + 12pi = 14pi =43.98 = 44 in^2

If it is helpful, plz give me Brainliest.

The closest to the total surface area of the cylinder is 44 inches²

where

r = radius

h = height

Therefore,

r = 2 / 2 = 1 inch

h = 6 inches

a = 2 × 3.14 × 1(1 + 6)

a = 6.28(7)

a = 43.96

a ≈ 44 inches²

Answer: 41

Step-by-step explanation:

You need to subtract the 82 by the 41 so 82-41 then you would find the missing part. Or you could add 4 to the 4 to make 8 and then add the 1 to the 1 to get 2

Answer:

D

Step-by-step explanation:

The zeros are the values of x on the x- axis where the graph crosses.

The graph crosses the x- axis at x = - 4 and x = - 6

Then x = - 4 and x = - 6 are the 2 zeros → D

Answer:

Dan is 110 miles from home at noon and is traveling at 55 miles per hour

Step-by-step explanation:

Mathematically, we have the general equation of a linear model as;

y = mx + b

m represents the slope of the model

b is the y-intercept of the model

Mathematically, what we have here is that there is a plot of distance against time

Distance is on the y-axis

time is on the x-axis

Now, the coefficient of the x-axis value is the slope

From what we have, the slope value is 55 miles per hour

Now, we have the y-intercept at 110

So, what this mean is that the distance from home is 110

So the correct answer here is that;

Dan is traveling at 55 miles per hour and he is 110 miles away from home

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

[tex] B_{x} - A_{x} = 7 - 4 = 3 [/tex]                    

Hence, the distance of point D from point C in the x-direction is:

[tex] D_{x} = C_{x} + 3 = 4 + 3 = 7 [/tex]

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

[tex] C_{y} - A_{y} = 8 - 2 = 6 [/tex]  

Then, the distance of point D from point B in the y-direction is:

[tex] D_{y} = B_{y} + 6 = 2 + 6 = 8 [/tex]

Therefore, the coordinates of the missing vertex (point D) are:

[tex] D = (D_{x}, D_{y}) = (7, 8) [/tex]    

b) The area of the rectangle is:

[tex] a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2} [/tex]

The perimeter is given by:

[tex] p = 2*(3 + 6) = 18 units [/tex]

I hope it helps you!          

Answer:

Step-by-step explanation:

do this is 2 parts

total = square + 1/2 circle

area of a square is side * side or  ... b/c the sides of a square are the same 2* side

area of a circle is Pi* r^2

total area = 12*12 + 1/2 * pi * 6^2

ta = 144 + 56.52

ta = 200.52
