The admission fee at a small fair is $1.50 for children and $4.00 for adults. on a certain day, 2200 people enter the fair and $5050 is collected. how many children and how many adults attended that day?

Answers

I would write systems of equations for this problem.

1.5x + 4y = 5050

x + y = 2200

From there solve the system of equations where x represents the number of children and y represent the number of adults.

x + y = 2200

x = 2200 - y

Plug "x" into the other system of equation.

1.5(2200-y) + 4y = 5050

3300 - 1.5y + 4y = 5050

2.5y = 1750

y = 700

Since you have the value for y, solve for x.

x + y = 2200

x + 700 = 2200

x = 1500

So, the solution is: 1500 children and 700 adults attended.

Just to check our answers:

1.5x + 4y = 5050

1.5(1500) + 4(700) = 5050

2250 + 2800 = 5050

5050 = 5050


The equation h(t)=−16t2+78t+45 gives the height of a firework, in feet, t seconds after it is launched from a platform. What is the height of the platform? Enter your answer in the box.

Answers

The height of the platform should be 45 feet. Hope this helps

The height of the platform is 45 feet.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The equation h(t)=−16t² +78t+45 gives the height of a firework

When a firework is launched from a platform, its height at time t=0 seconds is equal to the height of the platform.

To find the height of the platform, we can substitute t=0 into the equation:

h(0) = -16(0)² + 78(0) + 45

h(0) = 0 + 0 + 45

h(0) = 45

Therefore, the height of the platform is 45 feet.

Keiko runs 10 miles in 75 minutes. at the same rate, how many miles would she run in 69 minutes?

Answers

She would be running at a rate of 1 mile every 7.5 minutes. 75/10=7.5 minutes a mile. I figured the distance she would travel at 69 minutes is 9.2 miles. I guessed at the numbers when trying to figure it out. I don't know if you need it to be worked out to explain how you got that answer!

A basketball player scored 29 points in a game. The number of three-point field goals the player made was 29 less than three times the number of free throws (each worth 1 point). Twice the number of two-point field goals the player made was 15 more than the number of three-point field goals made. Find the number of free-throws, two-point field goals, and three-point field goals that the player made in the game.

A-10 free throws; 1 two-point field goals; 8 three-point field goals

B-11 free throws; 8 two-point field goals; 4 three-point field goals

C-10 free throws; 9 two-point field goals; 3 three-point field goals

D-10 free throws; 8 two-point field goals; 1 three-point field goals

Answers

If you let x represent the number of free throws.         
let y represent the number of two-point field goal.         
let z represent the number of three-point shots made.

Then the correct system of linear equations is as follows: 

x + 2y + 3z = 29 (The total number of points scored is 29.)
z = 3x - 29 (The number of 3-pointers was 29 less than 3 times the number of free throws.)
2y = z + 15 (Twice the number of 2-point shots made was 15 more than the number of 3-pointers.) 

Solution:
This basketball player scored 10 points via free throws (10 at 1 point each), 16 points via 8 two-point shots made, and 3 points via 1 three-point shots made. So, in the choice its letter D.

A machine manufactures wheels with a diameter of 70 cm. It is acceptable for the diameter of a wheel to be within 0.02 cm of this value. Write and solve an absolute-value equation to find the minimum and maximum acceptable diameters.

Answers

The expected diameter is 70 cm.

It is acceptable for the diameter to be within 0.02 cm of the expected value.
Therefore the acceptable values for the diameter, d, are
[tex]d \pm 0.02 = 70[/tex]

The minimum acceptable value of d is obtained from
d + 0.02 = 70
d = 69.98 cm

The maximum acceptable value of d is obtained from
d - 0.02 = 70
d = 70.02 cm

Answer:
Minimum acceptable diameter = 69.98 cm
Maximum acceptable diameter = 70.02 cm

To find the minimum and maximum acceptable diameters for wheels manufactured by a machine with a 70 cm diameter tolerance set within 0.02 cm, an absolute-value equation is used to determine the range of acceptable values.

The question is: A machine manufactures wheels with a diameter of 70 cm, and it can be within 0.02 cm of this value. To find the minimum and maximum acceptable diameters, we need to set up an absolute-value equation.

Let x be the diameter of the wheel.The absolute-value equation is |x - 70| ≤ 0.02.Solving this equation, the minimum acceptable diameter is 69.98 cm, and the maximum acceptable diameter is 70.02 cm.

an angle's measure is twice the measure of its complement. the larger angle is how many degrees greater than the smaller angle.

Answers

Two angles are complementary when they add up to 90 degrees

smaller angle = x
larger angle = 2x

x + 2x = 90
3x = 90
x = 90/3
x = 30°  ←  smaller angle 
larger angle = 2x = 2 * 30 = 60°

larger angle - smaller angle = 60° - 30° = 30°

The larger angle is 30 degrees greater than the smaller angle.

If P is the midpoint of ST, SP = x + 4, and ST = 4x, determine the length of ST

Answers

If P is the midpoint of ST then ST = 2SP

4x = 2(x + 4)
4x = 2x + 8
4x - 2x = 8
2x = 8
x = 8/2
x = 4

ST = 4x = 4*4 = 16 units

Answer:

ST = 16.

Step-by-step explanation:

Given  : P is the midpoint of ST, SP = x + 4, and ST = 4x,

To find :  Determine the length of ST.

Solution : We have given P is mid point of ST.

It mean P divide the ST in to two equal parts .

So, SP = PT .

We can say

ST  = 2 SP .

Plug the given values SP = x + 4, and ST = 4x,

4x = 2 ( x +4).

4x = 2x + 8.

On subtracting both sides by 2x

4x -2x = 8.

2x = 8

On dividing both sides by 2

x = 4.

ST = 4 * 4 = 16.

Therefore, ST = 16.

Solve the triangle. A = 46°, a = 31, b = 27

Answers

Final answer:

To solve the given triangle with A = 46°, a = 31, and b = 27, we use the Law of Sines to first find angle B, then use the sum of angles to find angle C, and finally, use the Law of Sines again to find side c.

Explanation:

To solve the triangle with the given information A = 46°, a = 31, and b = 27, we need to use the Law of Sines or the Law of Cosines. Since we have one angle and the side opposite to it (a = 31), as well as another side (b = 27), we first need to find angle B using the Law of Sines:

\frac{\sin(A)}{a} = \frac{\sin(B)}{b}
\frac{\sin(46°)}{31} = \frac{\sin(B)}{27}

By solving for sin(B), we get:

\sin(B) = \frac{\sin(46°) * 27}{31}

Next, we calculate the value of sin(B) and then angle B. After that, we can find angle C by using the fact that the sum of angles in a triangle is 180°:

A + B + C = 180°
C = 180° - A - B

Once we have angle C, we can use the Law of Sines again to find side c:

\frac{\sin(C)}{c} = \frac{\sin(A)}{a}

By rearranging and solving for c, we get:

c = \frac{\sin(C) * a}{\sin(A)}

This process will give us the lengths of all sides and the measurements of all angles, thus solving the triangle.

A rectangle has area 64 m2. Express the perimeter of the rectangle as a function of the length L of one of its sides. State the domain of P

Answers

A rectangle is a two-dimensional shape with two sets of equal, parallel sides. These dimensions are the length (L) and the width (W). The formula for the rectangle's area is the product of the two dimensions. The formula for perimeter is

P = 2L + 2W

Since
A = LW = 64
W = 64/L
Substituting to the formula for perimeter would be,

P = 2L + 2(64/L)
P = 2L + 128/L

Point M is the midpoint of LN. LM = 7x - 12 and MN = 3x + 16. Find LM.

Answers

Since point M is the midpoint of LN, LM and MN are equivalent in length.

7x - 12 = 3x + 16 (LM=MN)

7x = 3x + 28

4x = 28

x = 7

Now that we know the value of x, we can find the value of LM by plugging the value in the equation.

LM = 7(7) - 12

LM = 49 - 12

LM = 37
