ankoles [38]

Ratio and proportion

height:shadow=1.5:2

for the building, shadow=24

1.5:2=h:24
1.5/2=h/24
multiply both sides by 24
36/2=h

The diagonal of a square has length 10√2. Find the area of the square.

alex41 [277]

Answer: $A = 100$ square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

$Area = d^{2} / 2$

That is :

$A = \frac{(10\sqrt{2})^{2}}{2}$

$A = \frac{100(2)}{2}$

$A = 100$ square unit

How can Ari simplify the following expression? StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1

Zielflug [23.3K]

Answer:

$-\frac{8}{3}$

Step-by-step explanation:

Given

$\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}$

Required

Simpify

The very first step is to take LCM of the given expression

$\frac{-10 -4 - 2}{6}$

Perform arithmetic operations o the numerator

$-\frac{16}{6}$

Divide the numerator and denominator by 2

$-\frac{16/2}{6/2}$

$-\frac{8}{3}$

The expression can't be further simplified;

Hence, $\frac{5}{-3} - \frac{4}{2} + \frac{1}{-3}$ = $-\frac{8}{3}$
