Step-by-step explanation:

The complete question is

What is the length of leg y of the right triangle?

A right triangle with hypotenuse 26 and legs 24 and y

We need to use the Pythagorean Theorem, where $h=26$ and $x=24$ ,

$h^{2} =x^{2} +y^{2}\\ 26^{2}=24^{2}+y^{2}\\y=\sqrt{26^{2}-24^{2}}\\ y=\sqrt{676-576}\\ y=\sqrt{100}\\ y=10$

Therefore, the right answer is A. The length of the missing leg is 10 units.

A car travels 63 miles in 30 minutes. If the car travels at a constant speed, how many miles does the car travel in 50 minutes?

Anuta_ua [19.1K]

Answer:

The answer is B. 105 miles

Step-by-step explanation:

I just used a calculator and put in 30 times a random number until I got 63. So, 30 times 2.1 is 63. Then, I multiplied 50 times 2.1 to get 105 as the answer.

Answer:

$y=\frac{2}{3}x-6$

Step-by-step explanation:

Use the slope-intercept form:

$y=mx+b$

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:

$b=-6$

$y-intercept=(0,-6)$

To find the slope, take any two points from the line:

$(6,-2)(3,-4)$

Use the slope formula for when you have two points:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}$

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:

$(6(x_{1}),-2(y_{1})\\(3(x_{2}),-4(y_{2})$

$\frac{-4-(-2)}{3-6}$

Simplify parentheses (two negatives makes a positive):

$\frac{-4+2}{3-6}$

$\frac{-2}{-3}$

Simplify (two negatives make a positive):

$m=\frac{2}{3}$

The slope is $\frac{2}{3}$ and the y-intercept is $-6$ . Insert these into the equation:

$y=\frac{2}{3}x-6$

Finito.

The function f(r) gives the area of a circle with radius r. It can be written in equation form as f(r) = 3.14r2. What is f(5)?

alexandr402 [8]

F(r) = 3.14r^2....and ur looking for f(5)....so basically all u do is sub in 5 for r.

f(5) = 3.14 * 5^2
f(5) = 3.14 * 25
f(5) = 78.50 <===

Jack earns 100$ on the first day, 60$ on the second day, 150$ on the third day, 80$ on the fourth day and 90$ on the fifth day.

madam [21]

To solve this you would add up all the money then divide it by the number of days the guy worked

100+60+150+80+90= 480

480÷5= 96

Jacks average earnings was 96 dollars per day
