Answer:
Number of students who uses pencils = 64 students
Step-by-step explanation:
Pens : pencils = 3 : 2
Pen = 3
Pencil = 2
Total = 3 + 2 = 5
If there is a total of 160 middles school students how many of them used pencils?
Number of students who uses pencils = ratio of pencil / Total × number of students
= 2 / 5 × 160
= (2 * 160) / 5
= 320/5
= 64
Number of students who uses pencils = 64 students
Number of students who uses pen = ratio of pen / Total × number of students
= 3/5 × 160
= (3*160)/5
= 480/5
= 96 students

P=2h enter the profit in dollars for each hot dog
Answer: 8
Step-by-step explanation:
2x4
To get the profit of $85 the vendor must sell 43 Hot dogs.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have P= 2h where p is the profit and A is amount.
so, h= 1
P= 2
and, h= 2
P= 4
and, h= 3
P=6
and, h= 4
P=8
and, h= 5
P=10
and, h= 6
P=12
and, h= 7
P=14
and, h= 8
P=16
and, h= 9
P=18
and, h= 10
P=20
so, the amount of hot dogs is natural number.
If the vendor want the profit $85 then number of hot dogs sold
85 = 2h
h= 42.5

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x
Answer:
22
Step-by-step explanation:
Answer:
1/2 = x
Step-by-step explanation:
8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
-17 = -34x

Find the perimeter of the trapezoid. Leave your answer in simples radical form
Answer:
Perimeter = 105 + 15√3 in
Step-by-step explanation:
✔️Find the height of the trapezoid using trigonometric ratio:
Reference angle = 60°
opposite = height
Adj = 45 - 30 = 15 in
Thus:
Tan 60 = opp/adj
Tan 60 = height/15
height = 15*tan 60
height = 15√3 (tan 60 = √3)
✔️Find the slant height (hypotenuse) using Pythagorean Theorem:
Hypotenuse = √(height² + adj²)
Hypotenuse = √((15√3)² + 15²)
= √(675 + 225)
Hyp = √900
Hyp = 30
✔️Perimeter = 30 + 45 + 30 + 15√3
Perimeter = 105 + 15√3 in
Brooke went to the hardware store and bought 20 identical copper pipes. When Brooke lined up the pipes end-to-end, the line was 1 meter long. How long was each pipe?
Answer: 5cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 centimeters
Therefore, since Brooke went to the hardware store and bought 20 identical copper pipes and their total length is 1 meter long which is 100cm, the length of each pipe will be the title length of the Pipe divided by the number of pipes. This will be:
= 100 / 20
= 5cm each.
Each pipe is 5cm long.
If the simple interest on $7000 for 3 years is $1890, then what is the interest rate?
Answer:
0.09 or 9%
Step-by-step explanation:
I = Prt
Given:
I = 1890
P = 7000
t = 3
Work:
I = Prt
r = I/(Pt)
r = 1890/(7000 x 3)
r = 1890/21000
r = 0.09

Answer:
(a) Yes, AA postulate (b) SSS theorem long side: 35; total perimeter: 80Step-by-step explanation:
1. Both triangles are right triangles, and the vertical angles at C are the same measure. Hence, the triangles are similar because they have two congruent angles: the AA postulate applies.
__
2. The shortest-to-longest side ratios are ...
3 : 6 : 7
18 : 36 : 42 = 6(3) : 6(6) : 6(7) = 3 : 6 : 7
Corresponding sides are proportional, so the SSS theorem applies.
__
3. Larger triangle side lengths are a factor of 5 times those of the smaller triangle. The missing side of the larger triangle is 5×7 = 35. The total perimeter of the larger triangle is 20+25+35 = 80. The required length of fence depends on what is being fenced (not specified).

Answer:
a) 13.4
Step-by-step explanation:
This will use the pythagorem theorm. Which is a^2 + b^2 = c^2. You'll start with 12^2 + 6^2 = c^2. Then you'll solve from there.
12^2 + 6^2 = c^2
144 + 6^2 = c^2
144 + 36 = c^2
180 = c^2
then you'll find the square root of 180 (i don't have that symbol on my keyboard)
/180 = c
6/5 = c
then in decimal form it's 13.4164...
so rounded it's 13.4
5. Which integer best represents a deposit of $37? *
A. 37
B. −37
C. −⎪37⎥
D. −⎪−37⎥
Answer:
A. 37.
Step-by-step explanation:
In B, that is making a withdrawal.
In C, because of the *||*s around it, this means that the number inside of those lines will always be positive. But the negative is outside of the lines so it is still negative.
In D, you might think that the |-37| cancels out the - on the outside. But like I said, those lines mean that anything inside of the lines will always be positive. Meaning that the |-37| inside just becomes |37| and still turns negative because of the - on the outside.
