Answer:

70%

Step-by-step explanation:

I'm pretty sure its 70 because write it as a fraction 28/40 when divide them both and you get 0.7 which is 70. I hope that works

He has 70% of his questions correct.

This is why because 28/40 simplified is 7/10 and I know this is by dividing each number by 4. Also 7/10 and 0.7= 70%

1) A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk with the same pace in 2 hours? 3 hours? 3.5 hours?
Savatey [412]

You can solve this with proportion

1)    For 2h

9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles

For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get

x/4=9/2 => x=(9/2)*4=18 miles

2)  2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>

x= (320*7)/2 = 160 * 7 = 1120 acres

Good luck!!!

Suppose Johnny invests $41,745 into an account, which has been earning interest for many years and he now has a total of $39,974
Dmitriy789 [7]

Answer:

A negative number would be reasonable in the solution of the rate of the investment. It would be reasonable because Johnny started out with $41,745 in his account and ended up with $39,974 which means that the rate has to be negative.


please rate and thank : )

Jordon will play a triangle at his school’s music program. As its name suggests, the musical instrument is shaped like a triangl
guajiro [1.7K]

Answer:

A. AB

Step-by-step explanation:

Given that the musical instrument has a shape of ∆ABC, we can determine the shortest side that would be parallel to the ground by comparison of the 3 angles of the triangle corresponding to each side that is opposite each of them.

What this means is that, the larger angle would have the largest side opposite it. The medium angle will have medium length side opposite it, while the smallest angle will have the smallest side opposite it.

m < A = 59°

m < C = 57°

m < C = 180 - (59+57) (sum of angles in a triangle)

m < C = 64°

The smallest angle out of the three angles is angle C = 57°.

The side opposite it, is side AB.

Side AB is the shortest side of ∆ABC.

Therefore, AB should be parallel to the ground.

Which are the like terms in 2y3 – 4y2 + y + y3?
stealth61 [152]
C is the correct answer.  A, B, and C have terms with different powers of y, and as a result, these terms are not like.  C, however, has only multiples of y cubed, so it is a set of like terms.
