It would be awesome for some help! :3 Johnny Uses a wheelbarrow to move planting soil to a delivery truck. The volume of plantin
EleoNora [17]
We are given with
dimensions of wheelbarrow = 2ft x 3ft x 1.5 ft
dimensions of truck = 11 ft x 8 ft x 6 ft

The volume of the wheelbarrow is 2(3)(1.5) = 9 ft3
The volume of the truck is 11(8)(6) = 528 ft3
70% of this is
528 ft3 (0.7) = 369.6 ft3
Dividing this by the volume of the wheelbarrow
369.6 ft3 / 9 ft3 = 41.07
He would need to use the wheelbarrow 42 times.

the probability that a twelve year old has a brother or sister is 25%. suppose you survey 300 twelve year olds. about how many d
Genrish500 [490]

Answer:

n(B U S) = 75

Step-by-step explanation:

Explanation:-

<u>Probability</u>:-

P(E) = \frac{number of elements events in E}{total number of elementary events in the random experiment}

P(E) = \frac{m}{n}

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data  P(BUS) = 0.25

given total survey  n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) =\frac{n(BUS)}{n(survey)}

substitute given values, we will get solution

0.25 = \frac{n(BUS)}{300}

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75

Simplify the following expression by combining like terms.
Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x
