0.8h=112 solve for h

Mathematics
1 answer:
madreJ [45]3 years ago
8 0

Answer:

h = 140

Step-by-step explanation:

To solve for h, we will have to get the equation into the form h = _. That would be our answer.

0.8h = 112

Divide 0.8 from both sides to get rid of the coefficient of 0.8 on the left side.

h = 112/0.8

Change 112/0.8 to 1120/8 on the right side. This will make the fraction easier to simplify.

h = 1120/8

Simplify the fraction on the right side.

h = 140/1

140/2 equals 140.

h = 140

I hope you find this helpful. :)

Will ran the diagonal distance across a square field measuring 40 yards on each side. James ran the diagonal distance across a r
Oksi-84 [34.3K]

Answer: The distance across a rectangular field is longer distance.

Step-by-step explanation:

Since we have given that

Dimension of square = 40 yards

So, Dimensions of rectangle are :

Length = 25 yards

Width = 35 yards

So, Perimeter of rectangle would be

2\times (l+b)\\\\=2\times (25+35)\\\\=2\times 60\\\\=120\ yards

Diagonal of square would be

\sqrt{40^2+40^2}\\\\=\sqrt{1600+1600}\\\\=\sqrt{3200}\\\\=56.56\ yards

Hence, the distance across a rectangular field is longer distance.

HELP ILL GIVE BRAINLIEST QUICK!!
Semenov [28]

Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

Out of $20$ creepy-crawly creatures in a room, $80\%$ are flies and $20\%$ are spiders. If $S\%$ of the total legs belong to spi
Alex_Xolod [135]

Answer: 25

Step-by-step explanation:

Since, Total creepy-crawly creatures = 20

Out of which 80% are flies and 20% are spiders,

Thus, the total flies = 80% of 20 = 16

And, The total spiders = 20% of 20 = 4

Also, we know that the number of legs of a spider = 8,

⇒ Total legs belong to spiders out of 20 creepy-crawly creatures = 4×8 = 32

Again, the number of legs of a fly = 6

Thus, the total legs belong to flies out of 20 creepy-crawly creatures = 6×16 = 96

Hence, Total legs = 32 + 96 = 128

\text{ The percentage of legs that belongs to spider} = \frac{ \text{ Number of legs of 8 spiders}}{\text{ Total legs}}\times 100

= \frac{32}{128} \times 100

= \frac{3200}{28}

= 25\%
