Help ;/ 4.3 is 12.5% of what number?

Answers

Answer:

let x represent the number

12.5n/100=4.3

12.5n=4.3x100

12.5n=430

n= 430/12.5

n= 34.4

4.3 is 12.5% of 290.7
So...
X% times 4.3 equals 12.5
12.5 divided by 4.3 would give you 2.9069...
Now... it’s a percentage so multiply that by 100 and that would give you 290.69 or 290.7.

What is the missing angle in the triangle?



56°

65°

86°

68°

Answers

Answer:

65°

Step-by-step explanation:

We know that every triangle is equal to 180 degrees. Therefore, you have to subtract all angles by 180 to find what the missing angle is. The missing angle is 180-68-47. You can simplify this to 180-115. This is equal to 65. Therefore, the missing angle is 65 degrees.

If this helps please mark as brainliest

2) 10.6664 should be the adult weight of puppy B.

Sorry if I got the second or first wrong!

Answer:

#1 32 pounds

#2 10.67 pounds

Step-by-step explanation:

#1

25% is 1/4 of the puppy

and 100% is 4/4

so you have to do 8 x 4 = 32 pounds

#2

75% is 3/4 of the puppy adult size

Gordon attends Brown Deer College. This year's tuition costs $15,660. Gordon has a baseball scholarship that will pay $4,500 this year. His parents have saved $3,200 that he can use for this year's tuition. Gordon will need to borrow the rest. How much money will he need to borrow in student loans this year?

Answers

Tuition = $15,660

Baseball scholarship pays = $4,500

Parents pay = $3,200

$4,500 + $3,200 = $7,700 = How much is payed so far

$15,660 - $7,700 = $7,960

$7,960 is how much money he will need to borrow in student loans this year.

In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 17, 19, 20, 21, 23, 27, 28, 28, 28 and 32. Jean made the inference, "the average weight of the raccoon population is 25 pounds". Is this statement reasonable? Explain.

Answers

Answer:

    First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.

Step-by-step explanation:

hope this helps :)

No, because the average weight of the raccoons is 24.3 pounds.

Step 1) 17+19+20+21+23+27+28+28+28+32=243

Step 2)
243 divided by 10 = 24.3pounds

Diana rolls a regular dice, what is the chance that she will roll a 4?

Answers

Answer: 1/6

Explanation: There are six sides on a regular dice, and only one of the sides has a four.

guessing it’s a 6 sided dice, so it will be a 1 in 6 chance (1/6) that you’ll get a 4, hope this helps!

Please please please help me

Answers

Answer:

Step-by-step explanation:

Since all the answers are 100s I assume the sizes are 10, 10 and 20.

This would mean there are 2 sides of 10x10 and 4 of 10x20

The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800

Answer:  800?

A suit originally costing $240 is on sale for 25% off the original price. Sales tax is 7.5%. What is the final cost of the suit?

A) 180
B) $193.50
C) $258
D) $166.50

Answers

Answer:

$193.50

Step-by-step explanation:

start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.

then, subtract $60 from $240. equals 180.

next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.

lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.

180+13.5= $193.50
