The cost for roberta's college next year $11000 she has a Grant for $1500 a scholarship of $5000 she plans to earn 40% of the re

9966 [12]

She will have to pay $2,700.

She is starting with a bill of $11,000. If we subtract the 1500 grant and 5000 scholarship, she has left a bill of 4500.

She is going to earn 40% of it, so she still have to pay 60% of it.

0.6 x 4500 = 2700

REY [17]

Step-by-step explanation:

a + a r + a r^2 + a r^3 + a r^4 + a r^5 + ar^6

a r^2 = 108

a r^5 =-32

r^5/r^2 = - 32/108 = -8/27

r^3 = -2^3/3^3 =

r = - 2/3

A building makes a 90° angle with the ground. A ladder leans against the building, making a 110° exterior angle with the ground.

liberstina [14]

Answer:

A building makes a $90^{\circ}$ angle with the ground .The two interior angles are $70^{\circ}$ and $20^{\circ}$

Solution:

Given, a ladder which is against the building wall makes an exterior angle of $110^{\circ}$

And building makes a $90^{\circ}$ angle with the ground.

So, altogether it makes a right angle triangle with ladder as hypotenuse and ground as base leg and building as another leg.

Now, we know that, sum of exterior angles and interior angles equals to $180^{\circ}$

Here, in the case of ground and ladder, exterior angle is $110^{\circ}$ and interior angle is unknown.

Exterior angle + interior angle = 180

110 + interior angle = 180

Interior angle = 180 – 110

Interior angle = $70^{\circ}$

We have found one of the two interior angles of right angle triangle.

We know that, sum of angles in a triangle is 180 degree

Known Interior angle + unknown interior angle + right angle = 180

70 + unknown interior angle + 90 = 180

Unknown interior angle + 160 = 180

Unknown interior angle = 180 - 160

Unknown interior angle = $20^{\circ}$

Hence the two interior angles are $70^{\circ}$ and $20^{\circ}$
