Answer:
48
Step-by-step explanation:
25% × x = 12
0.25x = 12
then you would divide.
x = 12 / 0.25
x=48
so 48 students

Question
On a piece of paper, use a protractor to construct right triangle ABC with AB=3 in., m∠A=90°, and m∠B=45°.
What statement is true about the triangle?
A/1).AC=3 in.
B/2).BC=3 in.
C/3).BC=6 in.
D/4).AC=6 in.
Answer:
AC=3 in.
Step-by-step explanation:
It is given in the figure attached, in Δ ABC
∠ A = 90°
m∠B = 45°
AB = 3 in.
We have to find all sides of the triangle given
we will apply sine in Δ ABC to find the measure of AC
sinB =
Now by cross multiplication
BC = 3√2 in.
Now by Pythagoras theorem
BC²= AC² + AB²
(3√2)² = AC² + 3²
18 - 9 = AC²
AC = √9 = 3
Now we come to the options you have mentioned
AC = 3 in. is the correct answer.
There is 2 parts to this question
The first one is number 1
Answer:
1. 3 students
2. 1/10
Step-by-step explanation:
if there are 30 kids in the class, and 2/5 are in band that means 12 students are in band
30÷5 =6
6×2= 12
if 1/4 of those 12 play the saxophone, then 3 of those students play the saxophone.
12÷4= 3
3 is 1/10 of 30, which gives you the answer to the second question.

simmons and magda do push-ups for exercise. simmons does 42 push-ups in 360's. magda does 24 push ups in 3 min. who does push-ups at a faster rate?
Answer:
Simmons
Step-by-step explanation:
Simmons does 42 pushups in 360 seconds ,or 6 minutes. Magda does 24 pushups in 3 minutes. So by dividing by two you can find that Summons does 21 pushups in 3 minutes and 21<24
Answer: magda
Step-by-step explanation: a minute equals 60 seconds well to get to 360 you need five minute ( five sets of 60 )

Answer:
102 in²
Step-by-step explanation:
Please help me! Write the answer AND the explanation, please! :)
Answer:
C
Step-by-step explanation:
There is 8 on one side and 2a + 2 on the other so we can eliminate answer D.
8=2a+2
We take away 2 from both sides getting a on one side. So 6=2a. To find a we do the inverse way to solve the equation. To get 6 we multiply "a" by 2. To get "a" we dp 6/2 = 3. boom a=3 so C is your answer
PLEASE HELP ME! Explain simply and clearly.
The length of a line segment is 8 units.one end point is p(5,-3). which of these could be the other endpoint of the line segment?
A(-3,-3)
B(-3,-11)
C(5,8)
D(8,-3)
Answer:
Step-by-step explanation:
Solution
Distance between two points =
(x 2−x 1) 2+(y 2 −y 1) 2
Given, one point =(2,−3)
Let, other point =(10,b)
absicca is x cordinate
(10−2) 2+(b+3) 2=108 2+(b 2+9+6b)=10
Squaring both sides, we get
64+b
2
+9+6b=100
(b+3)
2
=36
∴ b+3=6 and b+3=−6
∴ b=3 and b=−9
Joseph has invited a group of friends over to watch a football game and is getting a party platter of spicy wings and sweet wings to serve. Joseph starts his order with 16 spicy wings. He plans to order more sweet wings than spicy wings.
Let n represent the number of sweet wings that Joseph might order. Which inequality models the story?
Answer:
Since Joseph plans to order more sweet wings than spicy wings, the inequality that models the story is:
n > 16
This means that the number of sweet wings (n) must be greater than 16.
Step-by-step explanation:
Answer: n > 16 im pretty sure
Step-by-step explanation: to graph just put the uncolored in dot on 16 and draw an arrow to the right

How many seconds would it take to fill a water balloon with a pint of water if the hose dispenses water at the rate of 20 pints/minute?
seconds?
Answer:
3 seconds
Step-by-step explanation:
1 minute = 60 sec
fill rate = 20 pints/60 sec = 0.33 pints/sec
t = time
(0.33 pints/sec)(t) = 1 pint
t = (1 pint) / (0.33 pint/sec) = 3 sec
Write a system of linear equations that has the ordered pair (3,-5) as it’s solution

Find the lateral area and total surface area of the rectangular prism. 12in, 12.5, 12.5, 1in, 7in, 12in.
Answer:
Surface area
Step-by-step explanation:
The surface area of a rectangular prism calculator gives us the answer: A = 2 × l × w + 2 × l × h + 2 × w × h = 2 × 8 ft × 6 ft + 2 × 8 ft × 5 ft + 2 × 6 ft × 5 ft = 236 ft²

Answer:
25
Step-by-step explanation:
1) Find [tex]\frac{1}{6}[/tex] of 48
To find this we have to do 48 divided by then multiplied by one!
48 ÷ 6 = 88 × 1 = 8This means that the teacher graded 8 quizzes before school.
2) Add how many was graded after school
We know that the teacher also did 15 of how many quizzes were left over after school.
Previously he/she had done 8 so we have to subtract this by 48
48 - 8 = 4015 more were done so we have to subtract this too...
40 - 15 = 2525 are left!
Hope this helps, have a lovely day! :)
Answer:
25 quizzes
Step-by-step explanation:
48/6=8
8+15=23
48-23=25
