Answer:

\frac{4}{9}

Step-by-step explanation:

So first rewrite the inside of the parentheses as improper fractions:

\frac{8}{9} ÷ (\frac{25}{4}*\frac{16}{5}-18)

Now simplify the inside:

\frac{8}{9} ÷ 2

Which is:

\frac{8}{18}=\frac{4}{9}

: Kenneth measured a hotel and made a scale drawing. The scale he used was 1 inch =4 feet. The actual length of a room in the ho
natulia [17]

The room is 5 inches long in the drawing.

Step-by-step explanation:

Given,

Scale drawing used by Kenneth;

1 inch = 4 feet

Ratio of scale = 1:4

Actual length of room = 20 feet

Let,

x be the length in drawing

Ratio of actual length = x:20

Using proportion

Scale ratio :: Actual ratio

1:4::x:20

Product of mean = Product of extreme

4*x=20*1\\4x=20

Dividing both sides by 4

\frac{4x}{4}=\frac{20}{4}\\x=5

The room is 5 inches long in the drawing.

gtnhenbr [62]

So.. Liliana used 4 crystals to race 14 zombie soldiers.

14 / 4 = 3.5. She can race 3.5 zombie soldiers if she uses 1 crystal. So, all you need to do it multiply 3.5 by 10 and you end up with 35.

So, Liliana is able to race 35 zombie soldiers with 10 power crystals.


Glad I could help!

Can someone help me for this question please? Why I got wrong answer. ASAP!!!
Snowcat [4.5K]

Answer:

a=8.06

A=29.74

B=60.26

Step-by-step explanation:

This is a right angled triangle and Pythagoras theorem is to be obeyed.

To get c, we follow the Pythagoras rule that says

Hyp² = Opp² + Adj²

c= Hypotenuse

c²= a² + b²

c² = 4² + 7²

c² = 65

c = √65 = 8.06

For angle A,

the opposing side to the angle = a = 4

The adjacent side to the angle = b = 7

Following trigonometry rule.

Tan A = opp/adj

Tan A = 4/7

A = Tan–¹(4/7)

A = 29.74°

For angle B,

Opposing side = 7

Adjacent side = 4

Tan B = 7/4

B = Tan-¹(7/4)

B = 60.26°
