a remote control truck can travel 20 feet in 3 seconds.what is trucks speed in miles per hour
1 hour = 3600 seconds
Calculate feet per hour first:
3600 seconds / 3 = 1200
1200 x 20 feet = 24,000 feet in 1 hour
1 mile = 5280 feet
Calculate miles per hour:
24,000 / 5280 = 4.54 miles per hour.
Round the answer as needed.
An angle is 68 degrees more than 3 times it’s supplementary angle find the measures of the two angles
28° and 152°
let the angle be x then supplementary angle = 3x + 68
Supplementary angles sum to 180° , hence
x + 3x + 68 = 180
4x + 68 = 180 ( subtract 68 from both sides )
4x = 112 ( divide both sides by 4 )
x = [tex]\frac{112}{4}[/tex] = 28
the angles are 28° and ( 3 × 28) + 68 = 84 + 68 = 152°

If elephant grass grows 2 2/3
inches a day, how many inches will it grow in 4 days?
In 4 days it will be 10 and 2/3
To find out how many inches elephant grass will grow in 4 days, multiply the daily growth rate by the number of days. The elephant grass will grow approximately 10 2/3 inches in 4 days.
Explanation:To find out how many inches of elephant grass will grow in 4 days, we need to multiply the daily growth rate by the number of days. The daily growth rate is 2 2/3 inches. To convert this mixed number to an improper fraction, we multiply the whole number (2) by the denominator (3), which gives us 6. Adding the result to the numerator (2), we get 8. So the daily growth rate is 8/3 inches.
Next, we multiply the daily growth rate by the number of days: 8/3 * 4 = 32/3 inches. To simplify this fraction, we divide the numerator (32) by the denominator (3), which equals 10 with a remainder of 2. So the elephant grass will grow approximately 10 2/3 inches in 4 days.

Find the y-intercept and the slope for the line. -2x+6y=5
Write your answer in simplest form
Y intercept means the y-coordinate of the point where the graph crosses the y-axis.
Given equation is:
[tex]-2x+6y=5[/tex]
Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.
[tex]-2(0)+6y=5[/tex]
[tex]6y=5[/tex]
y=[tex]\frac{5}{6}[/tex]
Slope-intercept form is y = mx + b
where m is the slope of the line and b is the y-intercept of the line {the number without a variable}
-2x+6y = 5
6y = 2x+5
y= [tex]\frac{2x}{6}+\frac{5}{6}[/tex]
Hence, slope is [tex]\frac{2}{6}or\frac{1}{3}[/tex]

Serena paid a tax of $288 on a house assessed at $48,000. Using the same tax rate, find the tax on a house assessed at $59,000.
Set up a proportion:
$288/$48000 = x/$59000
Cross multiply
16992000 = 48000x
x = 354
The tax on the $59000 house was $354
To find the tax on a house assessed at $59,000 using the same tax rate, we can set up a proportion and solve for the unknown tax value.
Explanation:To find the tax on a house assessed at $59,000 using the same tax rate, we can set up a proportion. The tax paid by Serena is $288 and the house assessed value is $48,000. Let's call the tax on the house assessed at $59,000 as 'x'. The proportion will be:
$$\frac{288}{48000} = \frac{x}{59000}$$
Cross multiplying, we get:
$$288 \times 59000 = 48000 \times x$$
Simplifying, we find:
$$x = \frac{288 \times 59000}{48000}$$
Using a calculator, we can evaluate this to find the tax on a house assessed at $59,000.

The graph shows the increase in temperature over time in an oven. What is the change in the y-values and x-values on the graph? The change in the y-values is 40 and the change in the x-values is 1. The change in the y-values is 1 and the change in the x-values is 40. The change in the y-values is 150 and the change in the x-values is 2. The change in the y-values is 190 and the change in the x-values is 3.
Answer:
Option A is correct.
Change in the y-values is 40 and the change in x-values is 1.
Step-by-step explanation:
Let x represents the time in minutes and y represents the temperature(in Fahrenheit).
Given two points on the line graph i.e,
[tex]A(x_1, y_1)= (2 , 150)[/tex] and [tex]B (x_2, y_2)= (3, 190)[/tex]
we have to find the change in the y-value and x-value on the graph:
Change in the x-values for the given points is;
[tex](x_2 - x_1)[/tex] = 3 - 2 = 1
Similarly,
Change in the y-values for the given points is;
[tex](y_2 - y_1)[/tex] = 190-150 =40.
Since, the slope or the rate of change of the given line graph is the ratio of the change in the y-value over the change in the x-value i.e, slope = 40.
Therefore, change in the y-values is 40 and the change in x-values is 1.

Suppose the sun casts a shadow off a 35-foot building. If the angle of elevation to the sun is 60°, how long is the shadow to the nearest tenth of a foot?
Final answer:
To find the length of the shadow cast by a 35-foot building with a 60° angle of elevation to the sun, we can use trigonometry. The shadow is approximately 60.6 feet long.
Explanation:
To find the length of the shadow, we can use the concept of trigonometry. In a right triangle, the opposite side is proportional to the shadow length and the adjacent side is proportional to the height of the building. Using the angle of elevation of 60° and the height of the building as 35 feet, we can set up the trigonometric equation as follows:
tan(60°) = x/35
Solving for x, we get x = 35 * tan(60°) = 60.6 feet. Therefore, the shadow is approximately 60.6 feet long to the nearest tenth of a foot.

A VHS tape holds at most 360 minutes. A tape already has a 120 minute movie on it. How many 30 minute sitcoms can be recorded on the remaining tape?
There are 8 sitcoms that can be recorded on the remaining tape.
Explanation:To find out how many 30-minute sitcoms can be recorded on the remaining tape, we need to subtract the duration of the existing movie from the maximum capacity of the VHS tape. So, 360 minutes - 120 minutes = 240 minutes remaining. Since each sitcom is 30 minutes long, we can divide the remaining time by 30 to find out the number of sitcoms: 240 minutes ÷ 30 minutes = 8 sitcoms can be recorded on the remaining tape.

Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5. If 45 cargo planes landed yesterday, how many passenger flights came in?
Answer:
A total of 72 passenger planes came in yesterday.
Explanation:
Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5.
Number of cargo planes landed yesterday = 45
Number of passenger planes landed = [tex]\frac{8}{5}[/tex] x Number of cargo planes landed.
Number of passenger planes landed yesterday = [tex]\frac{8}{5}[/tex] x 45
= 8 x 9
= 72 passenger planes.
So a total of 72 passenger planes came in yesterday.

Here are the numbers we have to use:
+7

+9
the problem would be 7-3-2+4+9=15
Now divide 15 by your total amount of games which would be 5.

The mean difference in scores over the five games played would be 3.
Hope this helps!
Answer:
3
Step-by-step explanation:
Given:
A volleyball team played five games, the team won by 7 points, lost by 3, lost by 2 , won by 4 and won by 9
To find : the mean difference in scores over the five games
Solution:
Mean basically refers to sum of all observations divided by number of observations.
The mean of scores over the five games refers to sum of all scores divided by 5.
Scores :
won by 7 points means + 7
lost by 3 means - 3
lost by 2 means - 2
won by 4 means + 4
won by 9 means + 9
Therefore,
sum of all scores = 7 - 3 - 2 + 4 + 9 = 15
Also, total number of games played by the team = 5
So, mean difference in scores over the five games = sum of all scores / total number of games played by the team = 15 / 5 = 3
Shannon is making identical balloon arrangements for a party she has 24 white balloons and 60 blue balloons she wants to arrangement to have the same number of each color what is the greatest number of Arrangements that she can make and every balloon is used
12 of each color will be used.
hope it helps
Answer: There are 12 greatest number of arrangements that she can make and every balloon is used.
Step-by-step explanation:
Since we have given that
Number of white balloons = 24
Number of blue balloons = 60
We need to find the greatest number of arrangements that she can make and every balloon is used.
So, For greatest number of arrangements we will find H.C.F.
So, H.C.F. of 24 and 60 = 12.
Hence, there are 12 greatest number of arrangements that she can make and every balloon is used.
