Answer:
10x3=30
Step-by-step explanation:
X=2 is 10 and x=5 is 30.
10 is the factor of 30, and 10 could be multiplied by 3 to get 30.
OR 30 could be divided by 10, and you‘ll get 3.
Hope this helped! :)
Please at least give Thanks.

The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student
Answers
Answer:
70
Step-by-step explanation
Find the diagram attached
Average = Sum of scores/sample size
Given the 7 numbers
20, 20, 20, 30, 80, 80, 80
Average = 50
5 = 20+20+20+30+80+80+80+x/8
x is the score of the 8th student
50 = 330+x/8
400 = 330+x
x = 400-330
x = 70
Hence the score of the 8th student is 70

Answers
Answer:
22.44 mi²Step-by-step explanation:
Step 1
Find the missing angle:
m∠H = 180° - (47° + 99°) = 34°Step 2
Find the missing sides by using the law of sines:
sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 miStep 3
Use Heron's formula for the area:
A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sidesFind s:
s = 1/2(5.9 + 7.7 + 10.4) = 12Find A:
A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²Please help.

At Z-Mart, after the discount it is 7/8 of the original price of 225,
at ABC Sports the final price is 200,
and at Bike World, after the discount it is 3/4 of the original price of 265
so
we multiply 225 by 7/8 to get 196.88,
which is lower than ABC Sports,
and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart
so Z-Mart or A) is correct.

A story owner wants to prepare 100 lb of a candy mix that she will she for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?
Answers
Answer:
1.65
Step-by-step explanation:
100 pounds of the mixture = 1.36 * 100 = 136 dollars.
She uses 20 pounds of jelly beans that cost
20 * .20 = 4.00
136 - 4 = 132 dollars left for 80 pounds of sugar candies.
80 pounds = 132 pounds of sugar candies.
1 pound = x
80/1 = 132 / x Cross multiply
80x = 132
x = 132 / 80
x = 1.65 / per pound

Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?
Answers
Answer:
35
Step-by-step explanation:
This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.
C(n,r)=C(7,3)
=7!(3!(7−3)!)
=7!3!×4!
= 35
Finally, we can see that the total number of possible outcomes is 35
