The answer would be A.

Explanation:

If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.

The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). if area = length × width, wh

viva [34]

Answer:

Area = x4 + 4x3 + 3x2 - 4x - 4

Length = x3 +5x2 + 8x + 4

Width = Area / Length.

Performing long division with polynomial.

x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1

Width = x-1

a) What is the probability that he is accepted to one of the two schools

this means P( standford or cal-poly)

P( standford or cal-poly) = P( standford) + P(cal-poly) − P( standford and cal-poly)

= 0.4 + 0.3 – 0.15

= 0.55

What is the probability that he does not get accepted at either school?

Prob that he gets neither = 1 − 0.55 = 0.45

Eric and Charles are on their high school track and field team. Eric is participating in hurdles and the javelin. For every 5 ho

Natali [406]

Answer: Charles practiced for 9 hours for the relay race last week.

Explanation:

Since we have given that

For every 5 hours that Eric spends practicing hurdles, he practices the javelin for 1.5 hours.

So, it means ,

For every 15 hours that spends practicing hurdles, he practices the javelin for

$1.5\times 3=4.5\ hours$

Now, we have also given that ,

Eric and Charles practiced javelin for the same amount of time,

It means Charles practiced javelin for 4.5 hours .

Now, we can relate that ,

For every 5 hours that Charles spends practicing for the relay race, he practices the javelin for 2.5 hours.

Let the time taken by Charles in practicing for the relay race last week be x.

If Charles practiced javelin for 4.5 hours, he will practice for relay race for

$\frac{5}{2.5}=\frac{x}{4.5}\\\\x=9\ hours$

Hence, Charles practiced for 9 hours for the relay race last week.
