After that do 30x70 so number of students times the 70% mean which gives 2100.
Now take the 2100 - 1240 = 860.
After that 860/10 = 86%
20 boys get 62 and 10 girls get 86 this all will equal to 2100.....2100/30 = 70
So the final answer is 86%

what is the additive inverse of [tex]\frac{2}{3}[/tex]
A. 3/2
B. 0
C. -2/3
D. -3/2
show al your work please due very soon
Answers
Answer:
your answer is C. -2/3
Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the additive inverse (opposite number) of a positive number is negative, and the additive inverse of a negative number is positive. Zero is the additive inverse of itself. In this case, -2/3 is the additive inverse of 2/3.

In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answers
Answer:
Part A
x is 46°
Part B
Alternate angles are angles that are in relatively opposite locations relative to a transversal
Step-by-step explanation:
Part A
∠DRP = 110° (Given)
∠QPA = 64° (Given)
∠QPR =
Given that AB is parallel to CD, we have;
∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)
Therefore, ∠APR = 115°
∠APR = ∠QPA + ∠QPR (Angle addition postulate)
∴ 115° = 64° + ∠QPR
∠QPR = 110° - 64° = 46°
x = 46°
Part B.
Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines
The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other
In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

A small pot holds 75% as much as a large pot.
If a small pot holds 36 units, how much does the large pot hold?
Answers
Answer:
63 units!!
Step-by-step explanation:
36x.75= 27
Add 27 to 36 to get the large pot.
Answer:
The large pot can hold 48 units of water.
Step-by-step explanation:
small pot holds 75% water of a large pot
small pot holds 36 units
let x be quantity of water in large pot
According to the question,
75% of x = 36 units
75/100 * x= 36
75x/100= 36
75x= 36*100
75x= 3600
x= 3600/75
x= 48 units
The large pot can hold 48 units of water.

The measures of two angles in a triangle are 32o and 78o. Which of the following equations could be used to find the measure of the third angle, x?
(the ¨o¨ is a degree symbol)
180−32+78=x
180−32=x−78
180−(32+782÷2)=x
32+78+x=180
Answers
Answer:
32+78+x=180
Step-by-step explanation:
All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.
Answer:
32 + 78 + x = 180
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
32 + 78 + x = 180
A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction
B) what is this number as a mixed number
Answers
Answer:
A)First were going to put our numbers in perspective.
[tex]\frac{7}{4}[/tex] ÷ [tex]\frac{8}{5}[/tex]
But to find the improper fraction, we have to cross multiply these numbers.
[tex]\frac{7}{4}[/tex] × [tex]\frac{8}{5}[/tex]
7 x 5 = 35.
4 x 8 = 32.
Now we have our improper fraction is [tex]\frac{35}{32}[/tex]
B)To turn our improper fraction into a mixed number, we will use division.
We know that the 32 can only go into 35 one time. We also know that the bottom number always stays the same. So our equation will look somewhat like this.
[tex]1\frac{?}{32}[/tex]
Now to fine the top number we will have to subtract 35 from 32 because we already know that 32 can go into 35 one time, so 35 - 32 = 3. So are mixed number will look like this.
[tex]1\frac{3}{32}[/tex]
This is our answer!
Answer:
7/4 ÷ 8/5
A. First, we need to do the reciprocal of 8/5.
7/4 x 5/8 = 35/32
B. Now, we need to convert it into a mixed number. Divide 35 by 32. 32 goes into 35 one time. 35 - 32 = 3, so remainder 3. We use 1 as the whole number since 32 goes into 35 one time. We use the remainder 3 as the numerator, and 32 as the denominator.

We need to use the formula :-
2 (l + b) × h ---> For Lateral surface area
2(30+30) h = 7200
2×60×h = 7200
120 × h = 7200
h = 7200/120
h = 60 cm
Now, volume = l×b×h
= 30×30×60
= 54000 cm³ is the required answer.
Hope it helps! :D
Answer:
54000cm³
Step-by-step explanation:
