Masha had 200 scoops of ice cream and Liz had 180 scoops. After they each ate an equal amount of scoops, the ratio of Masha’s sc

kherson [118]

Answer:

Each of them eat 140 scoops.

Step-by-step explanation:

Let x be the amount eaten by each of them,

Given,

The initial ice cream Masha has = 200 scoops

Final ice cream Masha has = ( 200 - x ) scoops

while the initial ice cream Liz has = 180 scoops,

Final ice cream Liz has = (180-x) scoops,

According to the question,

$\frac{200-x}{180-x}=\frac{3}{2}$

$400-2x=540-3x$ ( by cross multiplication )

$-2x=140-3x$ ( Subtracting 400 on both sides )

$x=140$ ( adding 3x on both sides )

Hence, each of them eat 140 scoops.

A drug trial is testing the effectiveness of two drugs. If 50 patients are given Drug A, 20 patients are given Drug B, and 100 p

Vsevolod [243]

So, to find the answer you'd first add up how many patients you have:
20+50+100 = 170.
In a fraction your total would go on the bottom. Then you'd take how many patients are taking a real drug, which is represented by 20+50 = 70. This number would go on top.

So, the probability of a patient NOT getting a placebo is 70/170. Simplified would be 7/17.

The answer is D. 7/17.

Julie and her brother go to Atlanta to ride the Sky View Ferris wheel. It measures 200 feet in diameter. I want to know the dist

Zinaida [17]

Answer:

a) Circumference of Ferris wheel.

b) $\text{Circumference} = \pi d$

c) 628 feet

Step-by-step explanation:

We are given the following in question:

Diameter of Ferris Wheel = 200 feet

a) Distance around Ferris wheel

The distance around Ferris wheel is given by the circumference of Ferris wheel.

b) Formula to calculate circumference

$\text{Circumference} = \pi d$

where d is the diameter of he wheel.

c) Distance traveled in one rotation

This will be given by the circumference of the Ferris wheel.

$\text{Distance} = \pi d = 3.14\times 200 = 628\text{ feet}$

Thus, the distance traveled in one rotation is 628 feet.
