Which is the correct choice please.

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  

ta da.. :P    total area is 200.52 [tex]ft^{2}[/tex]

Answer: D

Step-by-step explanation:

7×6^2  −3x

7×36−3x

which is 252-3x

Answer:

C: 246

Step-by-step explanation:

7 (2 + 4)² - 3 (2) = 7 (6²) - 6 = 7 (36) - 6 = 252 - 6 = 246

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:

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: 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

Step-by-step explanation:

The formula for the area of a parallelogram is the same formula to get the area of a rectangle. In a rectangle, the height is the area divided by base. Therefore, the height of the parallelogram would simply be the area divided by base.

Step-by-step explanation:

Answer:

A. -(100)/(3); value drops $100 every 3 years.

Step-by-step explanation:

The rate of change here, is the how much the value of the refrigerator increases per unit of time, in years. Since, the value of the fridge decreases, the rate of change is negative.

It is a linear graph i.e. the instantaneous rate of change and average rate of change are the same. Now, all you have to do is pick any two arbitrary points, preferably the x-intercept and y-intercept for simplicity and find the change in y and the change in x. The change in y and x will be the difference of the x and y coordinate of the points you chose. It does not matter which order you subtract in. Just remain consistent between your 2 points. The change in y is your rise, the change in x is your run. Slope is rise over run. So then divide.

Δy=400-0= $400

Δx = 0-12 = -12 yrs

Rate of change = rise/run = 400/(-12)=100/-3= -33.333 $/yrs

Answer:

The rate of of change is -100/3, or -33.33. This means that every year, the resale value of a refridgerator goes down by about $33.33

Step-by-step explanation:

rate of change formula : f(b)-f(a)/b-a

200-300/6-3

= -100/3

=-33.33

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:

$528 is the new price after the discount

Step-by-step explanation:

12% of $600

0.12 of 600

0.12 × 600 = 72

$72 is the discount price

Since it's a discount, you subtract the discount price from the original one.

$600 - $72 = $528
