Step-by-step explanation:
3/4 = .75
120 * .75 = 90
Of those 90 students 1/3 wore sandals.
1/3 = approximately .33
90 * .33 = 29.7
Therefore, around 30 students wore jeans and sandals.

Hunter owns a food truck that sells tacos and burritos. He sells each taco for $3.25 and each burrito for $6.50. Yesterday Hunter made a total of $520 in revenue from selling a total of 120 tacos and burritos. Graphically solve a system of equations in order to determine the number of tacos sold, x,x, and the number of burritos sold, yy.
what are the two equations?
Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y and x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
40 = y
x = 120-y
x = 120-(40)
x = 80

how many integers satisfy -5≥-7x and -15≥5x
The number of integers that satisfies the inequalities, -5 ≥ -7•x and -15 ≥ 5•x is zero or non
How can the inequalities be simplified?The given inequalities are;
-5 ≥ -7•x and -15 ≥ 5•x
Simplifying the inequalities gives;
-5 ≥ -7•x
Dividing both sides by -7 gives;
-5/-7 ≤ -7•x/-7 = x
Therefore;
5/7 ≤ x
Which gives;
x ≥ 5/7The second inequality is simplified as follows;
-15 ≥ 5•x
-15/5 ≥ 5•x/5
-3 ≥ x
Which gives;
x ≤ -3
Therefore;
-3 ≥ x and x ≥ 5/7
5/7 ≤ x ≤ -3
However, 5/7 > -3
The number of integers that satisfies the inequality, 5/7 ≤ x ≤ -3, is zero (no integer satisfies the inequality).
Therefore;
Non of the integers satisfies both -5 ≥ -7•x and -15 ≥ 5•x

17. Your class wants to raise at least $100 for a charity by collecting bottles. Each glass bottle earns $0.05. Each plastic
bottle earns $0.10.
a. Describe the numbers of glass bottles your class needs to collect if no plastic bottles are collected.
b. Describe the numbers of plastic bottles your class needs to collect if no glass bottles are collected.
c. Write an inequality that represents how many of each type of bottle your class can collect to reach the goal.
Considering the definition of an inequality, you get:
a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.
b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.
c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that:
Your class wants to raise at least $100 for a charity by collecting bottles.Each glass bottle earns $0.05. Each plastic bottle earns $0.10.Being:
"g" the numbers of glass bottles your class needs to collect."p" the numbers of plastic bottles your class needs to collect.a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is calculated as:
0.05×g≥100
Solving:
g≥100÷ 0.05

The total operating cost to run the organic strawberry
farm varies directly with its number of acres. What is
the constant of variation in this scenario?
If the total operating cost for a 20-acre organic.
strawberry farm is $551,520, how many acres are on a
farm with a total operating cost of $441,216?
acres
Answer:
A. How to determine the constant
Let the total cost be C
Let the number of acres be A
From the question given above,
C ∝ A
C = KA
K = C / A
Total cost (C) = $ 551520
Number of acres (A) = 20 acres
Conctant (K) =?
K = C / A
K = 551520 / 20
K = 27576 dollar/acre
B. How to determine the number of acres
Total cost (C) = $ 441216
Constant (K) = 27576 dollar/acre
Number of acres (A) =?
C = KA
Divide both side by K
A = C / K
A = 441216 / 27576
A = 16 acres

What will be the location of the x value of R' after using the translation rule (x + 4, y - 7), if the pre-image R is located at ( 24, -13)
The location of the x value of R' after using the translation rule is 28
What will be the location of the y value of R' after using the translation rule?The translation rule is given as:
(x + 4, y - 7)
The pre-image of R is located at (24, -13)
Rewrite as
R = (24, -13)
When the translation rule is applied, we have:
R' = (24 + 4, -13 - 7)
Evaluate
R' = (28, -20)
Remove the y coordinate
R'x = 28
Hence, the location of the x value of R' after using the translation rule is 28

Class comments
55° 60°
Answer:
Let's create this right triangle. We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C. If the ratio is 5:4, then it is A:C. 5+4 = 9. The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10. So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees. The smallest angle, angle C, is 40 degrees.

Answer:

Step-by-step explanation:
p^2 - 11p + 30
find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:
(p - 5)(p - 6)
Answer:
(p - 5)(p - 6)
Step-by-step explanation:
Given
p² - 11p + 30
Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)
The factors are - 5 and - 6, since
- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus
p² - 11p + 30 = (p - 5)(p - 6) ← in factored form

This is further explained below.
Write an equation of the parabola with focus (2, 2) and vertex (2, 6)?Generally, A planar curve that is mirror-symmetrical and has an approximation of the form of the letter U is called a parabola.
It agrees with a number of mathematical descriptions that, at first glance, seem to be very distinct from one another, but which can be shown to describe the same curves. A point and a line are two components that may be used to describe a parabola.
In conclusion, It can be shown theoretically that the equation of the parabola with focus (2, 2) and vertex (2, 6) is as follows:

1. The numerator of a certain fraction is 3 more than the denominator. If 3/2 is added to the fraction, the result is 4. Find the fraction.
2. If 3/8 is added to five times the reciprocal of a number, the result is 1. Find the number.
3. One car travels 390 miles in the same amount of time it takes a second car traveling 3 miles per hour slower than the first to go 372 miles. What are the speeds of the cars?
9514 1404 393
Answer:
5/2 8 65 mph, 62 mphStep-by-step explanation:
The first two problems can be solved in your head by working backward from the end result.
__
1. After 3/2 is added, the result is 4. Then we must be adding 3/2 to 4 -3/2 = 5/2. We notice that 5/2 already has the numerator 3 more than the denominator, so the fraction of interest is 5/2.
__
2. If 3/8 is added to a number giving a result of 1, the number must be 1 -3/8 = 5/8. That is 5 times 1/8. The number of interest is the reciprocal of 1/8, so is 8.
__
3. Let x represent the speed of the faster car. Then x-3 is the speed of the slower car, and the two times are ...
time = distance/speed
390/x = 372/(x-3)
390(x -3) = 372x . . . cross multiply
18x = 1170 . . . . . . . add 1170-372x
x = 65 . . . . . . . . . . divide by 18
The speeds of the cars are 65 mph and 62 mph.
