Anastaziya [24]3 years ago
5 0

Answer:

The question is asking which numbers are larger with respect to one another. An easy way to do this is to convert to decimals, or just memorize it. 1/2=0.5, 3/4=0.75, 2/3=0.666666. So descending order (largest to smallest) 3/4, 2/3, 1/2.

Maribel has $1.25 in her pocket. The money is in quarters and dimes. There are a total of 8 coins. How many quarters and dimes d
Temka [501]
0.25q + 0.10d = 1.25
q + d = 8....q = 8 - d

0.25(8 - d) + 0.10d = 1.25
2 - 0.25d + 0.10d = 1.25
-0.25d + 0.10d = 1.25 - 2
-0.15d = - 0.75
d = -0.75/-0.15
d = 5 <=== there are 5 dimes

q + d = 8
q + 5 = 8
q = 8 - 5
q = 3 <=== there are 3 quarters

Monica [59]
The answer is 6 inches, 3*3*3 equals 27, the current volume of the cube, 27*8 equals 216, the new volume, 6*6*6 equals 216, so the side lengths equal 6 inches.

A street light is mounted at the top of a 15-ft-tall pole. A man 6 feet tall walks away from the pole with a speed of 5 ft/s alo
harina [27]

Answer:

25/3 ft/s

Step-by-step explanation:

Height of pole , h=15 ft

Height of man, h'=6 ft

Let BD=x

BE=y

DE=BE-BD=y-x

All right triangles are similar

When two triangles are similar then the ratio of their corresponding sides are equal.

Therefore,

\frac{AB}{CD}=\frac{BE}{DE}

\frac{15}{6}=\frac{y}{y-x}

\frac{5}{2}=\frac{y}{y-x}

5y-5x=2y

5y-2y=5x

3y=5x

y=\frac{5}{3}x

Differentiate w.r.t t

\frac{dy}{dt}=\frac{5}{3}\frac{dx}{dt}

We have dx/dt=5ft/s

Using the value

\frac{dy}{dt}=\frac{5}{3}(5)=\frac{25}{3}ft/s

Hence, the tip of  his shadow moving  with a speed 25/3 ft/s when he is 45 feet from the pole.
