Answer:

x=17

Step-by-step explanation:

It is a right angle

so if we do

90-39=51

then we do 51/3

which will give us the answer of 17

3(17)= 51

39+51=90

Question 12 helllllllppppp plazzzzzzz

Eddi Din [679]

Answer:

Step-by-step explanation:

It says Renita takes minutes to ride half a mile.

She leaves 30 minutes before school.

Total distance is

$2\frac{1}{2} = \frac{1}{2}+ \frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2}\\$

$2\frac{1}{2} \ there \ are \ 5 \ times \ \frac{1}{2} \ mile .\\$

Therefore total time to reach school will be 5 x 5 = 25minutes.

Since she leaves 30minutes before school. She will reach 5minutes early before school.

Time between 22:30 and 04:20

Svetlanka [38]

The answer would be 5 hours and 50 minuets. It would be this because 2230 equals 10:30 count the hours between 1030 and 430 6 hrs then minus 10 min because the last hr isnt a full hour because it doesnt make it to 430.

The center of an ice rink is located at (0, 0) on a coordinate system measured in feet. sandi skates along a path that can be mo

WARRIOR [948]

The answers to the question are are the equations

y = 0.08x²-1.6x+13

y = 0.08(x-10)²+5

<h3>How to solve for the system of equations</h3>

David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).

Vertex form of quadratic function is

y = $a(x-h)^2+k$

13 = a(x-10)²+5

let x = 20

a(20-10)²+5

13 = 100a + 5

take like terms

13 - 5 = 100a

8 = 100a

divide through by 100

a = 0.08

hence the equation would be

y = 0.08(x-10)²+5
