Question 4 Multiple Choice Worth 4 points)

Semmy [17]

Answer:

Question No 4

The equation will be: $y=-\frac{1}{2}x+11$

Option B is correct answer.

Question No 5

The equation will be: $y=\frac{3}{4}x+4$

Option A is correct answer.

Step-by-step explanation:

Question 4

The option equations are in slope intercept forms, so we will write equation in slope intercept form.

The general equation of slope intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

Using the point (2,10) and (4,9) we can find slope

The formula used is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Putting values and finding slope:

$Slope=\frac{9-10}{4-2}\\Slope=-\frac{1}{2}$

So, we get slope m = - 1/2

Finding y-intercept

Using point (2,10) and slope m =1/2 we can find y-intercept

$y=mx+b\\10=-\frac{1}{2}(2)+b\\10=-1+b\\b=10+1\\b=11$

So, equation will be:

$y=mx+b\\y=-\frac{1}{2}x+11$

Option B is correct answer.

Question 5

The option equations are in slope intercept forms, so we will write equation in slope intercept form.

The general equation of slope intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

Using the point (0,4) and (4,7) from the graph we can find slope

The formula used is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Putting values and finding slope:

$Slope=\frac{7-4}{4-0}\\Slope=\frac{3}{4}$

So, we get slope m = 3/4

Finding y-intercept

Using point (0.4) and slope m = 3/4 we can find y-intercept

$y=mx+b\\4=\frac{3}{4}(0)+b\\4=0+b\\b=4$

So, equation will be:

$y=mx+b\\y=\frac{3}{4}x+4$

Option A is correct answer.

Sixty-four tickets are issued for a school

sweet [91]

Answer:

Each students will get 3 tickets and 2 brownies .

Step-by-step explanation:

Given as :

The total number of tickets issued for the school dance = 64

The number of brownies ordered for refreshment table = 96

Let the number of tickets given to each student = x

And The number of brownie given to each student = y

Now,

According to question

The tickets and brownies is distributed equally among students

So , Now, consider the tickets and brownies = n

Or, $\dfrac{n}{64}$ - $\dfrac{n}{96}$ = 1

Or, Taking LCM we get

$\dfrac{3 n - 2 n}{192}$ = 1

Or, $\dfrac{n}{192}$ = 1

∴ n = 192

Now,

The number of tickets given to each student = x = $\dfrac{192}{64}$

I.e x = 3

And The number of brownie given to each student = y = $\dfrac{192}{96}$

I.e y = 2

Hence Each students will get 3 tickets and 2 brownies . Answer

What is the volume of a sphere with a radius of nine units

vagabundo [1.1K]

The volume formula for a sphere is $V=\frac{4}{3}\pi r^3$ . If the radius is 9 units, we make the replacement accordingly. $V=\frac{4}{3}\pi (9)^3$ . 9 cubed is 729, so the formula now is $V=\frac{4}{3}\pi (729)$ . Multiplying 729 by 4 and then dividing by 3 gives us the volume, in terms of pi, to be $V=972\pi units^3$
