You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions.
9 ft x 9 ft
Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
Answer:
48.6 minutes
Step-by-step explanation:
First we must identify the area of the given wall :
A = L * W
A = 9 * 9
81 = 9 * 9
[tex]81ft^2[/tex]
Now we know that we can paint 75 square feet every 45 minutes so we must use proportion to find out how long it'll take you.
[tex]\frac{75}{45} *\frac{ft^2}{min}[/tex]
=
[tex]\frac{81}{x}[/tex] [tex]\frac{ft^2}{min}[/tex]
x = 45(81) / 75
x = 3645 / 75
x = 48.6 minutes
A passenger on a stranded lifeboat shoots two distress flares into the air. The first flare travels a maximum height 196 feet and lands in the water after 7 seconds. The height (feet) of the second flare above the water is given by f(t) = -16t(t-8), where t is time (seconds) since the flare was shot. Which flare travels higher? Which remains in the air longer?
Answer:
The second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare
Step-by-step explanation:
The given parameters are;
The height of the first flare = 196 feet
The duration the first flare spends in the air = 7 seconds
The function representing the height of the second flair is f(t) = -16t(t - 8)
Where;
t = The time since the passenger shot the second flare
The time the flair stays i the air is given by the time it takes for the height, f(t), to be 0 as follows;
f(t) = 0 = -16t(t - 8)
-16t(t - 8) = 0
t = 0, or t = 8
The time the second flare stays in the air = 8 seconds
The maximum height reached by the second flair is given by the finding the maximum point of the curve of the function as follows;
d(f(t))/dt = 0 = d(-16t(t - 8))/dt = -32t + 128 at the maximum point (the coefficient of t² is negative in the quadratic equation)
-32t + 128 = 0
128 = 32t
32t = 128
t = 128/32 = 4
t = 4 at maximum height and f(4) = -16 × 4 × (4 - 8) = 256 feet
The maximum height reached by the second flare f(4) = -16 × 4 × (4 - 8) = 256 feet.
Therefore, the second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare, with maximum height of 196 feet, and time in the air of 7 seconds.

Distance is 123
C. -62 & -145
|-125| - |-62|
= 125 - 62
= 63
Distance is 63
D. 56 & -89

Step-by-step explanation:
Selina walked 2 1/2 miles in 2/3 hour. Dennis 6 3/4 miles in 1 1/2 hours. Who walked faster and how much faster?
Answer:
Dennis walked faster by 0.75 miles/hr
Step-by-step explanation:
a)Selina's speed
speed= distance
time
= 2.5 miles = 3.75 miles/hr = the slower
2/3 hrs
b) Dennis' speed
speed = distance
time
= 6.75 miles = 4.5 miles/hr = the faster
1.5 hrs
difference in speed:
faster - slower
4.5 - 3.75
=0.75 miles/hr
Dennis walked 0.75 miles per hour faster than Selina's speed.
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To determine Selina's speed
speed = distance/time
speed = 2.5 miles/(2/3) hour
speed = 3.75 miles/hour
To determine Dennis' speed
speed = distance/time
speed = 6.75 miles/(1.5) hour
speed = 4.5 miles/hour
Here Dennis' speed is greater than Selina's speed which means Dennis walked faster.
So the difference in speed = Dennis' speed - Selina's speed
The difference in speed = 4.5 miles/hour - 3.75 miles/hour
The difference in speed = 0.75 miles/hr
Thus, Dennis walked 0.75 miles per hour faster than Selina's speed.

How do I solve 6a + 5a = −11
Answer:
a = - 1
Step-by-step explanation:
Step 1:
6a + 5a = - 11 Equation
Step 2:
11a = - 11 Combine Like Terms
Step 3:
a = - 11 ÷ 11 Divide
Answer:
a = - 1
Hope This Helps :)
The solution to the equation 6a + 5a = -11 is a = -1.
We have,
To solve the equation 6a + 5a = -11, we can combine the like terms on the left side of the equation and then isolate the variable a.
Step 1: Combine like terms
On the left side, we have 6a + 5a, which gives us 11a. The equation becomes:
11a = -11
Step 2: Isolate the variable
To isolate variable a, we divide both sides of the equation by 11:
(11a) / 11 = (-11) / 11
a = -1
Therefore,
The solution to the equation 6a + 5a = -11 is a = -1.

Part A (2 points)
Does the information on the sign represent a proportional relationship?
Explain how you know.
6
Answer: Yes. There's a proportional relationship
Step-by-step explanation:
We are told that Anthony and Miguel go to the store to purchase some new DVDs and that an advertisement in the window catches their attention as they saw that:
3 DVDs cost $22,50. This means the price of one will be:
= $22.50 / 3
= $7.50
5 DVDs cost $37.50. This means that the price for one will be:
= $37.50 / 5
= $7.50
Since the price of a DVD both cost $7.50, it means that the information on the sign represent a proportional relationship.
