Answer:

52% and 7

Step-by-step explanation:

There are 25 squares of which 13 are shaded , then

$\frac{13}{25}$ × 100% = 13 × 4% = 52°

(b)

1 square represents $\frac{1}{25}$ × 100% = 1 × 4% = 4%

Then 80% = 80% ÷ 4% = 20

That is for 80% , 20 squares require to be shaded

That is 7 more than the 13 already shaded

A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top

PtichkaEL [24]

Answer: 9.19 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.

Sin α = opposite side / hypotenuse

Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is distance between the top of the ladder and the ground.

Replacing with the values given:

Sin 45 = x/ 13

Solving for x

sin45 (13) =x

x= 9.19 ft

How many terms are in 10y2-3y+8

Sergio [31]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find how many terms are in $\pmb{10y^2-3y+8}$ .

$\triangle~\fbox{\bf{KEY:}}$

A term is a thing that's added or subtracted.

So let's compute the number of terms in this expression.

The first term is $\pmb{10y^2}$ .

Is anything added or subtracted from 10y²?

Sure! $\pmb{-3y}$ is subtracted from 10y².

Also, 8 is added to -3y.

Thus, this expression has 3 terms.

Hope it helps you out! :D
