If 40% of 57 students like
turkey sandwiches, how many
students don't like turkey
sandwiches?
Answer:
34 students
Step-by-step explanation:
Turn 40% to decimal = 0.4
Then multiply it to 57.
57 * 0.4 = 22.8
Round it.
22.8 = 23
Now subtract it to 57
57 - 23 = 34

Does anyone know what the slope for C = 22.5 - (1/160)m
The slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]
Recall:
A linear equation in slope-intercept form is given as: y = mx + b."m" is the slope."b" is the y-intercept.Thus, given the linear equation:
[tex]C = 22.5 - (\frac{1}{160}) m[/tex],
C represents y
m represents x
[tex]-\frac{1}{160}[/tex] represents the slope (m)
22.5 represents b.
Therefore, the slope of the linear equation, [tex]C = 22.5 - (\frac{1}{160}) m[/tex], is: [tex]-\frac{1}{160}[/tex]

One day at central high school, 1/12 of the students were absent , and 1/5 of those present went on a field trip. If the number of students staying oin school was 704, how many students are enrolled at central high
Answer:
960
Step-by-step explanation:
If 1/12 were absent, then 11/12 were present.
If 1/5 of those were gone, then 4/5 of those were present.
(11/12)(4/5)enrollment = 704 . . . 4/5 of 11/12 of the enrollment is 704 students
(11/15)enrollment = 704 . . . . . . simplify
enrollment = 704(15/11) = 960 . . . . . multiply by 15/11
960 students are enrolled at Central High.
Krista has a pocket full of nickels and quarters that makes $3.55. If she has a total of 27 coins in her pocket, how many are nickels and how many are quarters?
Answer:
Look down
Step-by-step explanation:
Two equations
x = Quarters
y = Nickles
25x + 5y = 355 -- 1
x + y = 27 -- 2
5x + 5y = 135 -- 2
20x = 200
x = 10
sub in 2
10 + y = 27
y = 17
x = 10
Quarters equal 10
1) The ratio of the number of boys to the number of girls at a school is 4:5. If there are 120 boys, how many students are there altogether?
A 53 C 150
B 96 D 270
Answer:
270 students all together. First you divide 120 by the ratio of boys. That'll get you 30, then multiply 30 by 5 which is the girls ratio and you'll get 150. Finnaly add 150 + 120 then boom your answer

The temperature of a city doubles during the day. It then decreases by 12.1ºF after the sun goes down. The temperature at the end of the day is −6.5°F.
What was the temperature at the beginning of the day?
(This is a question on k12)
the answer is 5.6
because 5.6-12.1=-6.5 which is the temperature at the end of the day
hope this helps I really take my time to do this:)
Answer:
The answer is 2.8
Step-by-step explanation:
Since the temperature at the end of the day is -6.5.
So you add 12.1ºF to -6.5 and you get 5.6.
5.6 is the temperature throughout the day.
The question asks for the temperature from
the start of the day and the question says it
doubles throughout the day. Therefore,
divide 5.6 by 2 which gets you 2.8.

y=-2x this is answer.
Step-by-step explanation:

Answer:
x + 2y -7 = 0
Step-by-step explanation:
The given line to us is ,
=> y = 1/2x + 2
On comparing to slope intercept form of the line ,
m = 1/2As we know that the product of slopes of two perpendicular lines is -1. Hence ,
m_perp = -2 .Given point is (1,3) . Using point slope form ,
x - 1 = -2( y -3) x -1 = -2y +6 x +2y -1 -6 = 0x + 2y -7 = 0Jada has 12 library books checked out and Han has 13less than that. How many books does Han have checked out?

∠A and \angle B∠B are supplementary angles. If m\angle A=(8x-25)^{\circ}∠A=(8x−25) ∘ and m\angle B=(7x-5)^{\circ}∠B=(7x−5) ∘ , then find the measure of \angle B∠B.
An38
Step-by-step explanation:
The measure of angle B is 93°
Here,
∠A and ∠B are supplementary angles.
∠A = (8x - 25)° and ∠B = (7x - 5)°
We have to find ∠B.
What are Supplementary angles?
Two Angles are Supplementary when they add up to 180 degrees.
Now,
∠A and ∠B are supplementary angles.
Hence, ∠A + ∠B = 180°
Here, ∠A = (8x - 25)° and ∠B = (7x - 5)°
Put in above equation we get;
(8x - 25)° + (7x - 5)° = 180°
15 x - 30 = 180
15 x = 210
x = 14
So, Measure of ∠B = (7x - 5)° is;
∠B = (7x - 5)° = ( 7 * 14 - 5) = 98 - 5 = 93°
Hence, The measure of angle B is 93°.

Large fluffy towels were on sale at a discount of 30%. If the sale price was $8.40, what was the original price?
Answer:
$ 12
Step-by-step explanation:
Think that, Original price of a towel is $ 100
Using the above we can create a equation like this. Let the Original price of the towel given in the question be x.
Original price Discount Sale price
100 30 70
x 8.40
Now let's make an equation like this,
[tex]\frac{100}{x} =\frac{70}{8.40}[/tex]
Use cross multiplication and solve for the x
100 × 8.40 = 70 x
[tex]840=70x[/tex]
[tex]\frac{840}{70} =\frac{70x}{70}[/tex]
[tex]x=12[/tex]
Therefore, the original price is $ 12
