What value of x will make the equation below true?
9x=72

Answer:

x=4,90

y=8.66

Step-by-step explanation:

pythagoras thereom:

7²-5²=24

√24=4.90

10²-5²=75

√75=8.66

Answer:

C: √74

Step-by-step explanation:

We have to use the Pythagorean theorem to answer this (a² + b² + c²). We have a and b so all we have to do is square 5 and 7 (a and b) so we get a² b², then we add this to get c² as stated by the Pythagorean theorem. So, 7² (7 x 7) is 49, and 5² (5 x 5) is 25. 25+49 (a² + b²) is 74 (c²). So the square root of this would be the absolute length of the hypotenuse because this is the hypotenuse squared. Meaning that the answer would be √74 (square root of 74)

Answer:

12a. 22.5%

12b. 77.5%

13. $4000

Step-by-step explanation:

12.

    a. 315/1400= 0.225 = 22.5%

    b. 1400-315=1085  1885/1400= 0.775 = 77.5%

13.

[tex]\frac{5}{100} = \frac{200}{4000}[/tex]

5/100 will be equal to 200/4000 so the hair stylist made $4000 in sales.

also if im wrong sorry!!

Step-by-step explanation:

There are supposed to be 180 degrees in every triangle.

Therefore, no triangles exist.

this cannot be solved due to a typo or smth

Step-by-step explanation:

benny wants 132 plates in all, and 144 (the amount of green plates) itself is already greater than 132

Answer:

Equation: 2x + 3x + 10 = 180

x = 34

Top angle = 68 degrees

Bottom angle = 112 degrees

Step-by-step explanation:

The two angles add to 180, so set them equal to 180.

2x + 3x + 10 = 180

5x + 10 = 180

     - 10    - 10

5x = 170

/ 5    / 5

x = 34

Plug x into angles,

2(34) = 68

3(34) + 10 = 112

Answer:

17

Step-by-step explanation:

c = a^2 + b^2 = 15^2 + 8^2 = 17

Answer:

Your answer is A.

Step-by-step explanation:

When finding the area, you multiply π (3.14) and the radius (r). Then, you square the product (x2).

So, it is A = πr2

Hope this helps! :)

Answer:

5

Step-by-step explanation:

use the pythagorean theorem

[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]

[tex] {h}^{2} = {(4)}^{2} + {(3)}^{2} [/tex]

[tex] {h}^{2} = 16 + 9[/tex]

[tex] {h}^{2} = \sqrt{25} [/tex]

[tex] {h}^{2} = \sqrt{25} = 5[/tex]

Step-by-step explanation:

Answer:

So the answer is 13 classes member and 9 non member

Step-by-step explanation:

so you gotta do 24 + 3x = 7y ok?

and x equals 13 so 39 + 24 = 63

and non member is 7x = 63

x = 9

Hope I helped :D

Answer:

Class A

Step-by-step explanation:

If you look a class a, you see that the box in the boxplot is in between 76 and 88, and that space shows 50% of the class

Answer:

XUY = 40 degrees

WUZ = 90 degrees

XUZ = 50 degrees

VUW = 40 degrees

VUY = 140 degrees

I hope this helps :)

Step-by-step explanation:

WUZ is a right angle, so 90 degrees. YUW is a straight angle, so it is 180 degrees, so WUZ + XUZ + XUY = 180, WUZ is 90 and XUY is 40, so 90 + 40 = 130, 180 - 130 = 50

XUZ is 50 degrees

Since VUW is on the opposite side of XUY, it is the same degrees as it, so VUW is 40 degrees

YUW is 180 degrees, so VUW + VUY = 180, VUW is 40 degrees, so VUY is 180 - 40 = 1400, VUY is 140 degrees

Now we have them all:

XUY = 40 degrees

ZUW = 90 degrees

XUZ = 50 degrees

VUW = 40 degrees

and finally,

VUY = 140 degrees

Reading this whole thing, it sounds sooo weird

Answer:

2.66 :)

Step-by-step explanation:

The answer is 8/3  or 2  2/3

Answer:

Explained below

Step-by-step explanation:

a = Amy

s = sister

s x 5 = a

Plug in the numbers:

2 x 5 = 10

4 x 5 = 20

6 x 5 = 30

8 x 5 = 40

As you can see, Amy's pay is shown as 5 times more than her sister's.

Hope this helps! :)

Answer:

Equation: "5x" or "5x + 0"

Step-by-step explanation:

This is a linear function since the change in x and y values is constant. Let "Amy's pay in dollars" be represented by x, and "Sister's pay in dollars" be represented by y. Since x value is going up by +10 every time, that will be our numerator, and since y value is going up by +2 every time, that would be the denominator, according to the slope equation: [tex]\frac{x}{y}[/tex]. Thus it would give the equation as [tex]\frac{10}{2}[/tex], if simplified, our slope will be 5/1 also can be written as 5. Now to find the y-intercept we have to see the y value where x value is 0. To get x = 0 you have to imagine the table given going backwards. Meaning just as how to move to the right of the table by adding 10 to the x-value and 2 to the y-value, you would have to subtract 10 from the x-value and subtract 2 form the y value. Keep doing this until you have 0 for x-value and notice the y-value would be 0. Hence, the y-intercept for this equation would be 0.

Hope this helps, Good Luck!

Answer:

the inequality is 4

Step-by-step explanation:

you would add 3 to both sides

13+3 = 16

4x > 16
