Answer:
119 student tickets and 95 non-student tickets
Step-by-step explanation:
I did a trial-and-error solution.
I started with 107 students and 107 non-students:
(107*$7)+(107*$12) = $2033
It was too high, which tells us that there should be more who paid for the cheaper price.
I ended up with 119 and 95:
(119*$7)+(95*$12) = $1973
Answer:
Sample Response: Partial and negative tickets cannot be sold, so the minimum number values of e and s are 0. If s = 0, then e = 16, and if e = 0, then s = 20. Therefore, the values of s are whole numbers from 0 to 20 and the values of e are whole numbers between 0 and 16. The greatest number of student tickets sold was 20 and the greatest number of nonstudent tickets sold was 16.

Use the Pythagorean theorem to find a whole number estimate of the length of the unknown side of the right triangle. The length of the unknown side of the triangle is approximately cm.
Answer:
12 cm
Step-by-step explanation:
Leg of one side = 5 cm
Hypotenuse = 13cm
According to the theorem,
A^2 + B^2 = C^2
5^2 + B^2 = 13^2
25 + B^2 = 169
Subtract 25 form both sides,
B^2 = 169 - 25
B^2 = 144
B = sqrt( 144 )
B = 12

Find the volume of the composite solid. Round your answer to the nearest tenth.
Answer:
67.0 cm³
Step-by-step explanation:
The composite shape is a hemisphere of radius 2 atop a cylinder of height 4 and radius 2. The volume formulas for a cylinder and a sphere can be used to find its volume. (Dimensions are in centimeters.)
HemisphereThe formula for the volume of a hemisphere is half that for the volume of a sphere:
V = (1/2)(4/3πr³) = 2/3πr³
For a radius of 2 cm, the volume is ...
V = 2/3π(2 cm)³ = 16/3π cm³
CylinderThe formula for the volume of a cylinder is ...
V = πr²h . . . . . . for radius r, height h
For the given dimensions, the volume is ...
V = π(2 cm)²(4 cm) = 16π cm³
TotalThe total volume of the solid is the sum of these volumes:
total = hemisphere volume + cylinder volume
total = ((16/3)π +16π ) cm³ = (64/3)π cm³ ≈ 67.0 cm³
The volume of the composite solid is about 67.0 cm³.
Can the sides of a triangle have lengths 1, 15 and 1
Answer:
No
Step-by-step explanation:
In a triangle sum of any two sides is always grater than the third side.
Here,

A patient takes vitamin pills. Each day he must have at least 420 IU of vitamin A, 5 mg of vitamin
B1, and 60 mg of vitamin C. He can choose between pill 1, which contains 120 IU of vitamin A, 1
mg of vitamin B1, and 10 mg of vitamin C, and pill 2, which contains 60 IU of vitamin A, 1 mg of
vitamin B7, and 15 mg of vitamin C. Pill 1 costs 30¢, and pill 2 costs 60¢. Complete parts a and b
below.
Final Answer:
Pill 1 is more cost-effective, meeting or exceeding daily requirements for vitamins A, B1, and C with lower cost (30¢) compared to pill 2 (60¢). It provides 480 IU of vitamin A, 5 mg of vitamin B1, and 60 mg of vitamin C with fewer pills, making it the optimal choice.
Step-by-step explanation:
The patient's daily requirements are 420 IU of vitamin A, 5 mg of vitamin B1, and 60 mg of vitamin C. Let's evaluate the contribution of each pill to these requirements.
Pill 1 provides 120 IU of vitamin A, 1 mg of vitamin B1, and 10 mg of vitamin C.
Pill 2 provides 60 IU of vitamin A, 1 mg of vitamin B7, and 15 mg of vitamin C.
To meet the vitamin A requirement, the patient can take 4 pills of type 1 (4 * 120 IU = 480 IU), while it would take 7 pills of type 2 (7 * 60 IU = 420 IU). So, pill 1 is more efficient for meeting the vitamin A requirement.
For vitamin B1, both pills contribute 1 mg each, and since the requirement is 5 mg, the patient needs to take 5 pills of either type.
For vitamin C, the patient needs 60 mg. Pill 1 provides 10 mg per pill, so 6 pills are needed (6 * 10 mg = 60 mg). Pill 2 provides 15 mg per pill, so 4 pills are needed (4 * 15 mg = 60 mg).
Considering the cost, pill 1 costs 30¢, and pill 2 costs 60¢. Since both pills are equally effective in meeting the B1 requirement and pill 1 is more efficient for vitamin A and equally efficient for vitamin C, the patient should choose pill 1 due to its lower cost.

Paula designed a three-dimensional scale model of a department store. The volume of
the scale model was 35 cubic feet. The ratio of the dimensions of the model to the
dimensions of the store was 1:20. Determine the volume of the actual department
store that Paula planned to build.
Answer:
V = 280000 cubic meters
Step-by-step explanation: Given that the volume of the scale model was 35 cubic feet. The ratio of the dimensions of the model to the
dimensions of the store was 1:20.
Let the volume of the actual department store that Paula planned to build be V. Then
35/V = (1/20)^3
35/V = 1/8000
Cross multiply
V = 8000 × 35
V = 280000 cubic meters
Answer: The volume of the actual department store is 280,000 cubic feet
Step-by-step explanation: The question has provided the volume of the model built by Paula, and that is 35 cubic feet. The volume of a three sided solid is given as;
Volume = L x W x H
This can also be conveniently expressed as;
Volume = L³ (which implies that the solid has all sides measuring the same for simplicity's sake)
However, given that the ratio of the model to that of the actual store is 1:20, we simply use the given ratio to substitute for the value of the side of the actual store, hence we now have dimension as;
Volume = L³
35 = L³
Add the cube root to both sides of the equation
∛35 = L
The dimension of the actual store which is an enlargement by a ratio of 1:20 now becomes;
Actual store = 20 x L
Actual store = 20 x ∛35
Actual store = 20 x 3.27106631018859
Actual store = 65.42132620377179
Therefore the volume of the actual store is given as;
Volume = L³
Volume = 65.42132620377179³
Volume = 280000
Therefore the volume of the actual store is 280,000 cubic feet

Recall that the scores in Mr. Young’s class had a mean of 78 and a standard deviation of 8. About what percent of students scored between 78% and 94%?
A. 47.5%
B. 34%
C. 13.5%
D. 68%
Answer:
B. 34%.

What is the equation of a line with a -y-intercept of -5 and a slope of 8.
a. y=8x+5
b .y=8x-5
c. y=-5x+8
d. y=-5x-8
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = - 5, thus
y = 8x - 5 → B
Answer:
B
Step-by-step explanation:
y = mx + b
m represents slope and b is the y intercept
so 8x is mx in this equation and -5 is b
