Answer:

It will take the driver 15 hours to deliver to 312 houses.

Step-by-step explanation:

Divide 2.5 by 130, you will get 52.Next add 52 by 52, you will get 104. Then multiply 104 by 3, you will get 312. After multiply 3 by 2, you will get 6. Last multiply 2.5 by 6, and you will have your answer.

2.5 ÷ 130 = 52

52 + 52 = 104

104 x 3 = 312

3 x 2 = 6

2.5 x 6 = 15

I Hope This Helps!

Answer:

6 hours. ( I DID IT USING PROPORTIONS!)

Step-by-step explanation:

houses/hours

130/2.5= 312/x

(cross multiply)

130x = 780

130x/130 = 780/ 130 (divide each by 130)

6 = h

SSSSS [86.1K]

A triangle has a 90° angle, and the other two interior angles are congruent. Explain how to find the measure of one of the two c
Salsk061 [2.6K]

Answer:

45 degrees

Step-by-step explanation:

Think of it like this the sum of the angles in a triangle are the always the same 180 degrees.

So now, we do 180 - 90 = 90 this is the sum of the other angles.

We shall assume that they are the same and divide 90/2 = 45 degrees each

Ok here are some things to understand while solving!

  • If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
  • If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
  • If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
  • If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
  • If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
  • Without knowing at least one side, we can't be sure if two triangles are congruent. (which we do!)

Hope this helped!

Can some please explain how to do the math
UNO [17]

Answer:

The enrollment drop is 12 students per year. The equation is 60=5d. The complete sentence would be the enrollment drop at the after school program dropped 12 students per year, and the equation is 60=5d

Step-by-step explanation:

So I will start with explaining the equation. 60 is the amount of students that dropped, 5 is the year, and d is the enrollment drop rate per year that you are trying to find. The way to use this equation is to isolate d. To do that you divide both sides of the equation by 5, this leaves you with 12 = d. Therefore your yearly enrollment drop is 12 students.


60 = 5d

60/5 = d

60/5 = 12

12 = d

Hopefully this explained your answer.
