Answer:

The smaller number is: 8

The bigger number is: 20

Step-by-step explanation:

Ok let's say the two numbers are x and y.

x is the smaller one, and y is the bigger one.

This is the equation to find x:

x + 4y = 88

x + y = 28

x - x + 4y - y = 88 - 28

3y = 60

y = 20

x + 20 = 28

x = 8

$360^o-150^o=210^o\\\\\dfrac{210^o}{360^o}=\dfrac{7}{12}$

$P_{LQM}=\dfrac{7}{12}\cdot2\pi\cdot14=\dfrac{7}{3}\pi\cdot7=\dfrac{49\pi}{3}\ cm$

$P_{QRP}=\dfrac{1}{2}\cdot14\pi=7\pi\ cm$

$P_F=\dfrac{49\pi}{3}+7\pi+3\cdot14\approx\dfrac{49}{3}\cdot\dfrac{22}{7}+7\cdot\dfrac{22}{7}+42=166\dfrac{2}{3}\ cm^2$

You roll a number cube. Find the probability and write your answer in the simplest form. P(4)= ---------------------------------

alina1380 [7]

Answer:

$P(4) = \frac{1}{6}$

$P(\text{not a 2}) = \frac{5}{6}$

$P(\text{3 or 5}) = \frac{1}{3}$

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Number cube:

A number cube is a dice, which has six sides, numbered 1 to 6.

P(4)

One the sides is a 4, thus:

$P(4) = \frac{1}{6}$

P(not a 2)

Of the 6 sides, one is a 2, and the other 5 are not 2. So

$P(\text{not a 2}) = \frac{5}{6}$

P(3 or 5)

One sides is 3, other is 5, 1 + 1 = 2. So

$P(\text{3 or 5}) = \frac{2}{6} = \frac{1}{3}$

The wheel on Ed's chair has a radius of 30 cm. If he travels 540π cm, the wheel will rotate _?_ times.

Bond [772]

So travel distance of a wheele
1 rotation distance=1 times circumverence so find circunference
circumfernec=2 times radius times pi
radius=30
30 times 2 time spi=60pi
so 60pi times x revolutions=540pi
divide both sides by 60pi
x revolutions=9
9 revolustion
B is the answer
