For this question, we use the Pythagorean theorem.

$a^2+b^2=c^2$

We know the lengths of the legs, a and b.
$a=3$
$b=4$

Now, let's solve for the hypotenuse, c.

$3^2+4^2=c^2$
$25=c^2$

Take the positive square root.

$\boxed{c=5}$

Hope this helps! :)

Answer:

? = x = 12

Step-by-step explanation:

Remark

This is a proportion question. A proportion is 2 equal ratios. The two triangles are similar, which means that a proportion can be set up.

? = x

x + 8

9 + 6

Equation

x/(x + 8) = 9 / (9 + 6) Combine

Solution

x/(x + 8) = 9/15 Cross multiply

15x = 9(x + 8) Remove the brackets

15x = 9x + 72 Subtract 9x from both sides

15x - 9x = 72 Combine

6x = 72 Divide both sides by 6

6x/6 = 72/6

x = 12

Answer x = 12

4+6d<52 How do u do this

muminat

Answer:

d < 8

Step-by-step explanation: Obviously, you need to find out what D is. First you do the opposite of positive 4 to make it 0. You have to subtract 4, so you therefore subtract 4 from 52 as well, which is 48. Now you find out what 48/6 is to get the value of d which is < (less than) 8. Any d value less than 8 will give us a valid answer, however any d value more than 8 will give you an invalid answer.

A students pays of 18 an hour is 4 more than twice the amount of the student earns per hour at an internship enter an solve an e

svp [43]

Answer:

the hourly pay fro the internship is $7/hr

Step-by-step explanation:

The statement can be written mathematically as below

$18 = 4 + 2x$

the hourly rate of the internship is $x$

solving the equation, we have

$18 = 4 + 2x$

subtract 4 from both sides of the equation

$18 - 4 = 4 +2x -4$

$14 = 2x$

$x = 14/2$

$x = 7$

the hourly pay fro the internship is $7/hr

Using Pythagoras in the first question
c= $\sqrt{16 ^{2} + 4^{2} } =16.4924$
which is approximately 16.5
for the second question
we also use Pythagoras
$b^2=c^2-a^2$
$\sqrt{13^{2}-12^2}=5$

How do I graph this problem?

KIM [24]

The easiest way to graph these equations is to place them in slope intercept form.
2x = 10 - 3y
3y + 2x = 10
3y = -2x + 10
y = -2/3x + 3 and 3/10
Then just place values in for x to determine y
If x = 0, y = -2/3(0) + 3 and 3/10; y = 3 and 3/10
x = 1; y = -2/3(1) + 3 and 3/10; y = 2 and 19/30
Repeat as needed for more points, then plot the points on the graph, and draw a line through the points.

The same can be applied to the second equation.
3x + 2y = 5
2y = -3x + 5
y = -3/2x + 2 and 1/2

x = 0; y = -3/2(0) + 2 and 1/2; y = 2 and 1/2
x = 1; y = -3/2(1) + 2 and 1/2; y = 1
Repeat as needed for more points, then plot points and draw a line through them.
