Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer: About 3 hours and 5 minutes to paint the room together.
Step-by-step explanation:
Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.
Room/Hour
1/5 ± 1/8 =8/40
8/40+5/40=13/40
How long to paint the room?
13/40 x 1= 40/13
40÷13=3.0777
So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes
Bob has a coin cup with four $1 tokens and two $5 tokens in it. He also has two $10 tokens and one $25 token in his pocket.
He randomly draws a token froin the cup, and then randomly draws a token from his pocket. What is the probability that he
will draw $30 in tokens?
OB.
. В
We want to find the probability that Bob will randomly draw $30 in tokens. We will find that the probability is P = 1/6 = 0.167
Finding the probability.
The only case where he draws $30 randomly is when:
He takes one $5 token from the coin cupHe takes the $25 token from his pocket.Then we need to find the probabilities for these two events.
For the first one, the probability will be equal to the quotient between the number of $5 tokens and the total number of tokens in the cup. There are 6 tokens in the cup and 2 of these are $5 tokens, then the probability is:
p = 2/6 = 1/3
For the second event the probability is computed in the same way, he has two tokens in his pocket and one of them is a $25 token, then the probability is:
q = 1/2
The joint probability, the probability that both of these events happen at the same time, is given by the product of the individual probabilities, so we get:
P = p*q = (1/3)*(1/2) = 1/6 = 0.167
So the probability that he draws $30 in tokens is P = 1/6 = 0.167.

Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts
Answer:
Company one charges $11 + $0.16 per min.
Then if you talk for x minutes, the cost will be:
C₁(x) = $11 + ($0.16 per min)*x
For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:
C₂(x) = $20 + ($0.11 per min)*x
Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.
C₁(x) = C₂(x)
$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x
($0.16 per min)*x - ($0.11 per min)*x = $20 - $11
($0.05 per min)*x = $9
x = $9/($0.05 per min) = 180 mins
If you speak for 180 minutes, the cost is the same in both companies.
Greg uses a triangular area of his back yard as a garden.If the area if his garden 1.248 square feet,whats the area of the garden?
Answer:
192 ft²
Step-by-step explanation:
Area of rectangular backyard = 1248 ft²
Width of backyard = 52 ft
Length = x
Area of rectangular backyard = Length * width
1248 = x * 52
x = 1248 / 52
x = 24 feets
Hence, x = height of triangular garden
Area of triangle = 1/2 base * height
Area = 1/2 * 16 * 24
Area = 192 ft²

Which function is best represented by this graph?
A. y = 1/2x + 6
B. y = −2x + 3
C. y = 2x + 6
D. y = −1/2x + 3
Answer:
d
Step-by-step explanation:
not a bc it has to be negative
not c bc its has to be negative
not b bc the slope is -1/2
IT'S D
Answer:
D
Step-by-step explanation:
from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.
Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.
we must then find the show of the line.
let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
so, let's label (0,3) as point 1 and (6,0) as point two. then,
x1 = 0
y1= 3
and
x2= 6
y2=0
Now we just plug in and simplify.
[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]
we now have our slope and y intercept, so we can plug them into our equation
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept.
our equation is thus
[tex]y = - \frac{1}{2} x + 3[/tex]
so, the answer is D

Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.
The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?
Answer:
As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.
Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.
Subtract the 2 hours from 10am:
= 10 - 2
= 8am
Subtract the 15 minutes from 45:
= 45 - 15
= 30
Put that together:
= 8:30 am
They left their house at 8:30 am using this scenario.
Each table in a library can seat up to 5 people. There are enough tables for 75 people. How many tables are there in the library?
Answer:
15 tables
Step-by-step explanation:
75/5 = 15
Answer:
There are 15 tables in the library.
Step-by-step explanation:
You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

Answer:
y = |x+1.5|
Step-by-step explanation:
Start with the graph of y = |x|. To shift it left by 1.5 units, replace x with x+1.5.
General rules for shifting graphs:
Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)Answer:
y=abs(x+1.5)

Answer:
The answers are A, B and C.
Step-by-step explanation:
To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57
Next Divide 21 on both sides. -57/21 is -36
You should have -3k > -57
Divide -3 on both sides. -57/-3 is 12
You should end up with k > 12
And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

She wants to include some information about recent sales but only has certain information about last month's sales. She currently offers ham, turkey and vegetarian sandwiches. She sells the ham sandwiches for $10 each and the turkey sandwiches for $11.25.
Last Month's Vegetarian Sales
Total Sandwiches Sold 75
Total Income $712.50
How much does Carmen charge for the vegetarian sandwich?
Answer:
[tex]X=9.5[/tex]
Step-by-step explanation:
From the question we are told that:
Total Vegetarian Sandwiches Sold [tex]T_{vs}=75[/tex]
Total Vegetarian Sandwiches Income [tex]T_{vi}=$712.50[/tex]
Generally the equation for Cost of vegetarian sandwich is mathematically given by
[tex]X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}[/tex]
[tex]X=\frac{T_{vi}}{T_{vs}}[/tex]
[tex]X=\frac{712.50}{75}[/tex]
[tex]X=\$9.5[/tex]
