What is the area of Figure ABCD? answer choices are A:54 B:60 C:66 D:72

Solve for x X/6 = 10 A) X = 4 B) X = 10 C) X = 16 D) X = 60

Lina20 [59]

hi

x/6 = 10

In a equation , you can use every math operation you know as long as you do the same thing on both sides.

Here we have x/6 = 10

But what I want is x .

Here X is split in 6. So I 'm going to multiplicate all by 6 to find the original amount of X

In bold operation that are often not written but that you must understand to do that kind of exercices.

So : x/6 = 10

(x/6) *6 = 10 *6

6x/6 = 60

x = 60

The radius on a certain. Goodrich tire is 34 inches to the nearest inch how far will the tire have traveled In 3 revolutions

myrzilka [38]

Answer:

640.968 inches

Step-by-step explanation:

Given data

Radius= 34in

The expression for the circumference is

C= 2πr

substutite

C= 2*3.142*34

C= 213.656

This means that in 1 revolution the tire will travel 213.656 in

Hence in 3 revolutions it will travel

=213.656*3

=640.968 inches

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.

7j+5-8k when j=0.5 and k=0.25

Tomtit [17]

Answer:

6.5

Step-by-step explanation:

To perform this kind of exercise, it is necessary to replace the value indicated in each variable each time you find the variable in the equation.

$7j+5-8k$

If j=0.5 and k=0.25, replace the value of each variable.

$7(0.5)+5-8(0.25)=$

now perform the indicated operations

$7(0.5)+5-8(0.25)=3.5+5-2=6.5$
