Agroup of friends were working on a student film with a budget of $500, which they
spent on equipment and costumes, They spent $55 on costumes, What percent did
they spend on equipment?
Answer:
89%
Step-by-step explanation:
500-55=445
445/500=0.89
0.89x100=89
$500- $55= $445
445/500 = 89/100
89/100 × 100/1= 89%

The following sphere has a diameter of 18 cm.
Answer: A
Step-by-step explanation:
a basket contains red, green, yellow apples. An apple is selected at random if p(red) is 2/5 P(yellow) is 1/4 what is p(green)?
A. 3/20
B. 7/20
C. 1/10
D. 13/20
The probability of getting the green apple is 7/20 option (B) 7/20 is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
P(red) = 2/5
P(yellow) = 1/4
The sum of the probability of the event is 1.
P(red) + P(yellow) + P(green) = 1
2/5 + 1/4 + P(green) = 1
P(green) = 1 - (2/5 + 1/4)
P(green) = 7/20
Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.

Denise bikes 3 miles to her friend's house, and then she bikes home. The average rate biking to her friend's house is twice the average rate coming home. Write and simplify an expression for the time it takes Denise to make a round-trip in terms of the average rate coming home x. Hint : Use d = rt.
Using the relation between velocity, distance and time, it is found that the expression for the total time is given by:
[tex]t = \frac{9}{2x}[/tex]
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex].
Denise bikes 3 miles to her friend's house, hence:
[tex]v_1 = \frac{3}{t_1}[/tex]
[tex]t_1 = \frac{3}{v_1}[/tex]
The average rate biking to her friend's house is twice the average rate coming home, hence, on the return, [tex]v_2 = 0.5v_1[/tex]:
[tex]v_2 = \frac{3}{t_2}[/tex]
[tex]t_2 = \frac{3}{v_2}[/tex]
[tex]t_2 = \frac{3}{0.5v_1}[/tex]
[tex]t_2 = \frac{6}{v_1}[/tex]
The total time is given by, considering [tex]v_1 = 2v_2 = 2v = 2x[/tex], as we want to consider x the rate coming home:
[tex]t = t_1 + t_2[/tex]
[tex]t = \frac{3}{2x} + \frac{6}{2x}[/tex]

What is the radius of this circle if the circumference is 18 (pie) cm? c= 18 (pie) cm 3 cm 9 cm 18 cm 36 cm
Answer:
9, if you round to 2 Decimal Places.
(C = 18π = 18 × π = 56.54 (2 DP))
r = C ÷ 2π
= 56.54 ÷ 2 × π ≈ 9
A cube is numbered 1 through 6. If the cube is rolled twice, how many of the possible outcomes will have two even numbers? 3 9 18 36
======================================================
Explanation:
3/6 = 1/2 of the numbers on the cube are even (2,4,6)
If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.
There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.
---------
Those nine outcomes are listed below
A = 2, B = 2A = 2, B = 4A = 2, B = 6A = 4, B = 2A = 4, B = 4A = 4, B = 6A = 6, B = 2A = 6, B = 4A = 6, B = 6You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.

What is the midline of the function graphed below?
y = 1
y= 0.5
y = 0
y =2
The midline of the given graphed function for the y-coordinate is equal to y = 0.
The midline of a set of functions, you need to determine the average of their highest and lowest points.
For the functions represented in the graph,
y = 0.5.
The highest point is 0.5 for the graph.
y = -0.5
The lowest point is-0.5.
The midline of the set of functions is the average of their highest and lowest points.
Midline represented by a horizontal line.
Midline is the line that exactly passes through the midpoint of the highest and the lowest point.
Here on y-axis we have ,
Highest coordinate = 0.5
Lowest coordinate = -0.5
Midline point = ( highest point + lowest point ) / 2
Substitute the value we get,
⇒midline point = ( 0.5 + (-0.5))/ 2
⇒midline point = 0 /2
⇒midline point = 0
Therefore, the midline of the function of the graph is y = 0.

Mechanical energy is as much of potential and kinetic energy. Mechanical energy is never lost but only transformed from one form to another. As long as all the mechanical energy is as much as the potential energy then the kinetic energy is 0J. The mechanical energy of an object is found by summing its potential energy and kinetic energy.
A biased coin is flipped twice.
The probability of the coin landing on tailsis 0.4. Find the probability the coin lands on tails exactly once.
Answer:
0.48.
Step-by-step explanation:
There are 2 ways that a tail lands once:-
Tail + head or
head + tail.
Prob(Tail on one throw) = 0.4
Prob(Head on one throw) = 1 - 0.4 = 0.6.
Prob(Tail first then head) = 0.4 * 0.6 = 0.24
Head then tail has the same probability (0.6*0.4).
So the requred probability = 0.24 + 0.24
= 0.48.
