X^3 = 125 over 27 CAN I PLEASE GET HELP

Zinaida [17]

X³ = 125/27

Cube root both sides to isolate the variable:

∛x³ = ∛(125/27)

x = ∛(125/27)

∛125 = 5, ∛27 = 3

x = 5/3

What is 37.25% in simplest form of a fraction

Viktor [21]

If you have a graphing calculator, you can type 37.25/100 then that would equal 0.3725. Then you press the MATH button and select frac. This will give you 149/400

Answer ASAP, Will give brainliest!!

Brut [27]

Answer:

First. 115°

Second. 65°

Third. 65°

Fourth. 7

Fifth. 425.25

First

angle DAB = angle ADC (since this is an isosceles trapezoid)

Second

In a trapezoid adjacent angle are supplmentary (that is their sum is 180°)

180-115 is 65°

Third

(Same reason as second)

Fourth

The side 3x+4 is same as the opposite side

So 3x + 4 = 25

on solving you get x = 7 in

Fifth

$area \: = \frac{1}{2} \times length \: of \: the \: perpendicular \: (b1 + b2)$

area = 1/2 × 13.5 (20+43)

area = 1/2 × 13.5 × 63

Thus area is 425.25

The roof of a high rise is in the shape of an isosceles triangle with a base of 89 feet. The perimeter of the roof is 281 feet.

inysia [295]

Answer:

96 ft

Step-by-step explanation:

Perimeter= a (base)+b (side)+c (side)

281 = 89 +b + c

281 -89 = b + c

192 = b+ c ( however in an iscoceles triangle, 2 sides aree equal therefore b and c will be equal)

So: 192/2 = 96

Two twin sisters, Gwen and Jackie, are both 20 years old in the year 2050. Jackie takes off on a round-trip to Vega, 25 light-ye

Contact [7]

Answer:

C. about 25 years.

Step-by-step explanation:

We have been given that two Jackie takes off on a round-trip to Vega, 25 light-years away. She travels at an average speed close to the speed of light, say, 0.9999c.

To find time it will take Jakie to reach Vega, we will divide the distance of Vega by Gwen's speed.

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

$\text{Time}=\frac{25}{0.9999}$

$\text{Time}=25.00250$

$\text{Time}\approx 25$

Therefore, it will take approximately 25 years for Jakie to reach Vega and option C is the correct choice.
