What is the value of X? show all of your work

Mathematics
1 answer:
Lapatulllka [165]3 years ago
6 0

Answer:

5

Step-by-step explanation:

We need to use Pythagoras' theorem.

For this we can use the pythagoras formula a^2+b^2=c^2 and rearrange this

We then will have 8^2+b^2=89

(because 89(sqrt) squared is 89)

We can then solve for what x is.

We take away 64 from 89 which is 25

the square root of 25 is 5

Therefore x=5

1 ) Find the volume of a cylinder with diameter 22 in and height 15 in.
OverLord2011 [107]
1. The volume of the cylinder is calculated through the equation, V = πr²h. Substituting the known values,
                 V = π(22 in/2)²(15 in) = 1815π in³ = 5701.99 in²
2. The answer to this item is letter "C. area of the base x height".
3. The volume of the prism is 5 x 5 x 10 cm or equal to 250 cm³.

Which of the following could be the graph of 3x + 4y = 12?​
Elan Coil [88]

Answer:

A graph that goes through (4, 0), (8, -3), (0, 3), and (-4, 6)

Step-by-step explanation:

Hello!

To find what this looks like it is easier to put it into slope-intercept form which is y = mx + b

To get our equation to look like that we have to get y by itself

3x + 4y = 12

Subtract 3x from both sides

4y = -3x + 12

Divide both sides by 4

y =- \frac{3}{4}x  + 3

We now know the y-intercept is (0, 3)

Now we follow the slope to give us more points

More points are (4, 0), (8, -3), and (-4, 6)

The answer would be a graph that goes through those points.

Hope this helps!

What is the distance between the point (-7,3) and (4, -5) on a coordinate plane?
Evgesh-ka [11]
To find this, use the distance formula. D= square root over... (x2-x1)^2+ (y2-y1)^2. Now plug in your coordinates.
D= square root... (4- -7)^2+ (-5-3)^2. Simplify. 4- -7=11 (two neg= positive) -5 -3= -8. So,
D= square root... 11^2+ -8^2. Simplify. 11^2= 121. And -8^2=64. Now just take the square root after adding. 121+64= 185. And the square root of 185 isn’t a whole number, so your final answer is D= (square root over) 185. Hope this helps
