The speed of the truck is higher (or lower) than the speedometer value
when a larger (or smaller) than standard sized tire.
Responses:
The speed with a 28.2 inches tire is actually approximately 71.3 mphThe actual speed if a 24 inch tire was used would be 60.7 mphHow does the size of the tire determine the speed?The standard tire size diameter = 25.7 inches
Diameter of the replacement tire = 28.2 inches
Circumference of the standard tire = π·25.7 inches
1 mile = 63,360 inches
65 miles = 65 × 63,360 inches
[tex]Number \ of \ rotation =\dfrac{63,360 \times 65}{\pi \times 25.7} \approx \mathbf{ 51,008.85}[/tex]
Distance travelled by the replacement tire with the same number of
rotations is therefore;
[tex]Distance =\dfrac{63,360 \ in. \times 65}{\pi \times 25.7 \ in.} \times \pi \times 28.2 \ in. \approx \mathbf{4519022.6\ in.}[/tex]
Actual distance travelled in one hour = 4519022.6 ÷ 63,360 ≈ 71.32
The actual speed of the truck when the speedometer read 65 mph is; 71.32 mph
Second part; Tire diameter = 24 inches
Distance traveled in one hour = 51,008.85 × π × 24 ≈ 3845976.68
Distance traveled in one hour ≈ 3845976.68 inches
3845976.68 inches ≈ 60.7 miles
The actual speed if a 24 inch tire is used is approximately 60.7 mph
Details of the truck speed with different sized wheels
The speed if the original 25.7 inch tires is used will be the speed on the speedometer, which is 65 mph. However the actual speed with the new 28.2 inch tires is approximately 71.32 mph. The speed if the wheels were replaced with a 24 inch tire is approximately 60.7 mphLearn more about rotation and speed here:

Answer:
20 vegetable plants
Step-by-step explanation:
We must multiply the 40% (representing the amount of vegetable plants) by 50 (the total number of plants) to get 20 vegetable plants.
Alternatively, you could do 50 - (50 * 60%).
What is the SLOPE of HI ? Justify your answer hurry PLEASE
Step-by-step explanation:
since it is in the same line as DE, both have the same slope.
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.
and so by using the coordinates of D and E
x changes by +4 (from 8 to 12).
y changes by -8 (from 32 to 24).
the slope is therefore
-8/+4 = -2

Ethans birthday day party started at 4:30 p.m. the last guest at 6:32 p.m. how long did Ethans birthday last
assuming the last guest left at 6:32pm thus that'll be the duration of the party.
from 4:30 to 5pm is only 30 mins, from 5 to 6:32 is 1hr and 32 mins, now let's add the 30 mins from before, 1hr + 32 + 30, that's 1hr and 62 minutes, or namely 2hrs and 2 minutes.

a game used a standard of six sided dice what is the probability it will be a five
Answer:
1/6
Step-by-step explanation:
As mentioned, a regular dice has 6 sides: each labeled numbers 1 through 6. There are a total of 6 outcomes, so the denominator is 6. Since there is only a single 5 on the dice, the numerator is 1.
Therefore, the probability is 1/6.

$8.50 per hour for 40 hours and time and a half for 4 hours.
Answer:
$391.00

Pay per hour = $8.50
Time and half pay per hour = Pay per hour + 1/2 (Pay per hour)
= $8.50 + $4.25 = $ 12.75
Problem: $8.50 × 40 = $340.00
$12.75 × 4 = $51.00
= $391.00

We are given the sequence as;
−5,−4,−1,4,11,20,31
Difference between the consecutive terms in order is seen to be; +1, +3, +5, +7, +9, +11
Thus, the pattern is;
-5 + 0 = -5
-5 + 1 = -4
-5 + 4 = -1
-5 + 9 = 4
From the pattern above, we can deduce that the nth term is gotten from the expression; -5 + (n - 1)²

Step-by-step explanation:
1. What is the area of the wall that surrounds the garage door?
Notice that the wall can be broken into two parts, a parallelogram and a triangle. The triangle's base would be 30 - 18 (as it is stated that the parallelogram's length is 18), while the height is shared with the rectangle's width, which is 12:
Area of triangle = 1/2bh
b = 12
h = 12
Area of triangle = (12 * 12)/2 = (144)/2 = 72 ft²
Area of parallelogram = bh
b = 18
h = 12
Area of parallelogram = (18 x 12) = 216 ft²
216 + 72 = 288 ft²
Next, find the amount missing because of the garage door. It is given that the door's area can be found by multiplying the length and side (both 9ft). Subtract the gotten number from the total amount:
Area of parallelogram = bh
b = 9
h = 9
9 x 9 = 81 ft²
288 - 81 = 207 ft²
A) 207 ft²
~
First, note that there are two full rows in the bottom. This can be made into the rectangle. The rest would be solved using the triangle formula. Add the two results together at the end to get your total units.
Rectangle:
base = 9 units
height = 2 units
Area of Rectangle = base x height
= 9 x 2
= 18 units²
Triangle:
base = 9 units
height = 4 units
Area of Triangle = (base x height)/2
= (9 x 4)/2
= (36)/2
= 18 units²
Add the two areas together for your total units²:
18 + 18 = 36 units²
36 units²
~
The "base" of the triangle is 3 ft greater than the height of the triangle. The given height is that it is 12 ft. This means that the base is 15 ft.
Use a² + b² = c² to solve for the sides:
c = hypotenuse = 21 ft
b = base = 15 ft
c² - b² = a²
21² - 15² = a²
(441) - (225) = a²
a² = 216
√a² = √216
a = √216 = 6√6
~
I am not too sure if there is actual enough information that can be used to solve for this triangle. I understand that you will need the answers soon, so I will try to work on it and edit my answer later on. In my opinion, they would need to give at least one more measurement or information regarding which side is which to be able to obtain the answer. If i had to guess, I would guess as well the largest one, considering the 12 ft and 21 ft. Again, they will need to define "b", as well as what the "base" & "height" would be.

solve the equation by completing the square x^2-3x-18=0
Answer:
x = -3, 6
Step-by-step explanation:
First, add 18 to both sides
x² - 3x - 18 = 0
+ 18 + 18
x² - 3x = 18
Add 9/4 to both sides because that is the square of half of -3
x² - 3x + 9/4 = 18 + 9/4
Multiply both sides by 4 to get rid of the fractions
(x² - 3x + 9/4 = 18 + 9/4)4
4x² - 12x + 9 = 72 + 9 = 81
Factor the left side of the equation
(2x - 3)² = 81
√(2x - 3)² = √81
Because of the square root, this will result in a positive number and a negative number
2x - 3 = 9
2x - 3 = -9
For both equations, add 3 to both sides then divide by 2
2x - 3 = 9
+ 3 +3
2x = 12
2x/2 = 12/2
x = 6
2x - 3 = -9
+ 3 + 3
2x = -6
x = -3
