Answer:
It flies 380 miles fewer
Step-by-step explanation:
The correct question is as follows;
Scientists are preparing two satellites to be launched. The equation y=820x represents the number of miles, y, that the satellite, Space Explorer B, flies in x hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?
Solution;
For explorer B
The equation is;
y = 8200x
This mean that in 1 hour, it flies 820 miles
For explorer A
28,800 miles in 24 hours
In one hour, we have 28,800/24 = 1,200 miles
The number of fewer miles that explorer A travels will be ;
1200 miles - 820 miles = 380 miles fewer

1. One factor is a two digit number between 1 and 10 2. One factor is a two digit number between 1 and 10 ( different from the first) 3. The product is greater than 8. But less than 10
Answer: 3.5 * 2.5 = 8.75
Step-by-step explanation:
The factors are to be less than 10 but are should be two digit numbers. The only way this is possible would be if they had decimals.
Which two numbers below 10 can give a product less than 10 but more than 8?
3 and 3 would give 9 which is the closest to our constraints.
Both numbers cannot be similar however and have to have a decimal but the factors should be around 3 but not up to 4 as this would pass the 10.
3.5 * 2.5 = 8.75 would work.

Answer: [tex]61.9miles/hr[/tex]
Step-by-step explanation:
given data:
distance travelled by the car = 195 miles
time taken = 3 hours and 15mins
solution
average speed of the car
[tex]= \frac{195miles}{3hrs15mins} \\\\= 61.9miles/hr[/tex]
Answer:
The average speed is [tex]v=60 miles/h[/tex]
Step-by-step explanation:
The equation of the average speed os given by:
[tex]v=\frac{\Delta x}{\Delta t}[/tex] (1)
here:
Δx is just 195 miles
Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)
So we just need to put this into the equation (1)
[tex]v=\frac{195}{3.25}[/tex]
Therefore, the average speed is [tex]v=60 miles/h[/tex]

The family built a house that has a length and width in a ratio of 5: 4, what is the length and width of the house if the total area of two identical floors is 160m2
I hope it will help u , please Brain -list the question
Step-by-step explanation:As given that
L:W=5:4
L/W=5/4
L=(5/4)W
hence we also know that
Area of rectangle= L*W
As given A=160m2
putt the value of A and L=(5/4)W in above equation ,
hence 160 = (5/4)W * W
W^2 = 160*4/5
W^2 = 32*4
W^2=128
taking square root
W= +_ 11.3
but length can't be negative so we take positive value of W
W=11.3 m
Now for L putt in above equation,
L=5/4 * 11.3 = 14.12 m

In 60 seconds, a car in a parade travels 0.2 mile. The car traveled the last 0.05 mile in 12 seconds. How long did it take for the car to travel 0.1 mile?
Answer:
First 0.1 miles: 32 seconds
Last 0.1 miles: 28 seconds
Step-by-step explanation:
The car traveled 0.2 mile in 60 seconds.
The last 0.05 miles were done in 12 seconds.
Then the first 0.2 - 0.05 = 0.15 miles were done in 60 - 12 = 48 seconds. The speed of the car was: 0.15/48 = 0.003125 mi/s
At this speed it takes 0.1/0.003125 = 32 s to travel the first 0.1 mile.
In the second 0.1 mile, 0.05 miles are done at the same speed than before. It takes 0.05/0.003125 = 16 s, the next 0.05 miles were traveled in 12 seconds, making a total of 16+12 = 28 seconds

Solve for c.
2(c +1) = 10
Answer:
c = 4
Step-by-step explanation:
[tex]2(c+1) = 10[/tex]
Lets divide both the sides by 2.
[tex]=> \frac{2 (c+1)}{2} = \frac{10}{2}[/tex]
[tex]=> c + 1 = 5[/tex]
Now , lets substract 1 on both the sides.
[tex]=> c + 1 - 1 = 5 - 1[/tex]
[tex]=> c = 4[/tex]
The solution to the equation 2(c + 1) = 10 is c = 4.
We have,
To solve for c in equation 2(c + 1) = 10, we will apply the distributive property and simplify the equation step by step.
Let's solve it:
Distribute the 2 to the terms inside the parentheses:
2c + 2 = 10
Move the constant term (2) to the right side by subtracting 2 from both sides of the equation:
2c + 2 - 2 = 10 - 2
Simplifying further:
2c = 8
Divide both sides of the equation by 2 to solve for c:
(2c) / 2 = 8 / 2
Simplifying further:
c = 4
Therefore,
The solution to the equation 2(c + 1) = 10 is c = 4.

Paula has a large ball of yarn that she is going to use to knit a scarf for the winter. Every square inch on the scarf requires a certain number of yards of yarn from the ball. A linear model of this situation contains the values (11 , 352.99) and (30 , 126.7), where x represents the number of square inches knitted on the scarf, and y represents the number of yards remaining on the ball of yarn. How many yards of yarn did Paula start with?
Answer:
She started with 484 yarns
Step-by-step explanation:
Given
[tex](x_1,y_1) = (11,352.99)[/tex]
[tex](x_2,y_2) = (30,126.7)[/tex]
Required
Number of yarns she started with
The interpretation of this question is to calculate the y intercept.
We strt by calculating the slope (m)
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{352.99 - 126.7}{11 - 30}[/tex]
[tex]m = \frac{226.29}{-19}[/tex]
[tex]m = -11.91[/tex]
Next, we calculate the linear equation as follows;
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex](x_1,y_1) = (11,352.99)[/tex]
[tex]m = -11.91[/tex]
[tex]y - 352.99 = -11.91(x - 11)[/tex]
[tex]y - 352.99 = -11.91x + 131.01[/tex]
Make y the subject
[tex]y= -11.91x + 131.01 + 352.99[/tex]
[tex]y= -11.91x +484[/tex]
A linear equation has the form
[tex]y=mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
By comparison.
[tex]b = 484[/tex]
Hence, she started with 484 yarns

A car is traveling at 45 miles per hour. Once the car starts to brake, it's speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45
Determine how many seconds it takes for the car to stop.
Answer: 55t
Step-by-step explanation:
The time taken by the car to stop is 1.28 seconds.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that a car is travelling at 45 miles per hour. Once the car starts to brake, its speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45.
The formula to calculate the speed is written as,
V = s / t
Here s = 10t + 45 substitutes the value in the formula and calculate the time,
45 = ( 10t + 45 ) / t
45t = 10t + 45
35t = 45
t = 45 / 35
t = 1.28 seconds

Minnie is making tea. She knows that her tea tastes best if she lets her tea bag sit in the hot water for exactly fifteen minutes. However, depending how hot the water is, she may have to leave her tea bag in the water for 2 minutes more or less than usual. Write and solve an absolute value equation to describe this situation
Answer:
|x - 2| = 15 ; |x + 2| = 15
Step-by-step explanation:
Given that:
Wait time = 15 minutes
Variation in wait time depending on level of hotness = 2 minutes
X ± 2 = 15
x + 2 = 15 or x - 2 = 15
x = 15 - 2 = 13 or x = 15 + 2 = 17
Hence, to express the above as an absolute value equation :
|x - variation| = mean time
|x - 2| = 15 ; |x + 2| = 15
Which of the following is a zero for the function f(x) = (x - 15)(x + 1)(x - 10)?
