Chef Talbot is baking 6 blueberry pies. If he uses 3/4 of blueberries in each pie, how many pints of blueberries will he need??
Answer:
4 2/4 pints
Step-by-step explanation:
Well if you multiply 6 by 3/4 it equals 18/4 and if you turn that into a mixed number it will give you 4 2/4.
So in conclusion, Chef Talbot will use 4 and a half pints of blueberries.

Step-by-step explanation:
850 calls
1000:100=10
1%=10
10×85=850
Discount is the reduction in value. The total number of calls not answered this is 150 calls
Discount and percentagesGiven the following
Total number of calls = 1000 calls
If 15% of those calls were not answered, the total calls that were not answered is given as:
Total call not answered . = 0.15 * 1000
Total call not answered = 150 calls
Hence the total number of calls not answered this is 150 calls

Solve the following system of equations graphically on the set of axes below.
Y=1/3x+6 y=-5/3x-6
Answer:
I can not solve it in the system of the image, but i will give you the graph so you can copy it, or at least see how it is done.
First, we have the lines:
y = (1/3)*x + 6
y = (-5/3)*x - 6
To graph these lines, you must find two points for the lines and then draw a line that connects the points.
To do it, you can evaluate each line in two different values of x, for example for the first line we can have:
y(0) = (1/3)*0 + 6 = 6 (then we have the point (0, 6))
y(3) = (1/3)*3 + 6 = 7 (then we have the point (3, 7))
And for the second line, we will have:
y(0) = (-5/3)*0 - 6 = -6 (then we have the point (0, -6))
y(3) = -(5/3)*3 - 6 = -11 (then we have the point (-3, -11))
Now with those points we can graph the lines, and the solution of the system of equation will be the point where the two lines intersect.
The graphs of the lines are shown below:
Where the grey line is the first one, and the green is the second.
In the graph, you can see that the lines intersect in the point (-6, 4)
Then the solution for the system is x = -6, and y = 4.

Answer: 384 ft^2
Step-by-step explanation:
Like it said set up a proportional equation and solve for dimensions in feets.
The scale factor saids 0.75 in = 2 ft
And the dimensions are 6 in by 9 in
Now using the scale solve for how many feets will make 6 inches and how many feets will make 9 inches .
[tex]\frac{0.75}{6} = \frac{2}{x}[/tex] Solve by cross multiplying
0.75x = 12
x = 16
[tex]\frac{0.75}{9} = \frac{2}{x}[/tex] Cross multiply
0.75x = 18
x = 24
Now since we know the new dimensions are 16ft by 24ft then we will multiply them together to find the area .
16 * 24 = 384 ft^2

will it take to fill this pool full?
Answer: 480 minutes or 8 hours
Step-by-step explanation:
24,000 ÷ 50 = 480.
It will take 480 minutes to fill the pool.
480 minutes ÷ 60 is also 8. So it will take 8 hours to fill the pool, or 480 minutes. Whichever one you want to use.
Hope this helps!
Answer:
480 Minutes or 8 Hours
Step-by-step explanation:
If you do 24,000 divided by 50 you get a result of 480

Male the shapes look similar by turning the smaller to be the same as the bigger one the compare side and then find xThe number of adult Americans from a random sample of n adults who support a bill proposing to extend daylight savings time is a binomial random variable. Assume that its probability will be approximated using the normal distribution. Describe the area under the normal curve that will be computed in order to determine the probability that more than Americans support the bill.
Answer:
Right of X = 635.5
Step-by-step explanation:
By using the normal approximation to the Binomial random variable, we usually make use of continuity correction.
According to the rule of continuity;
P(X ≤ k) becomes P( X ≤ K + 0.5)
P(X < K) becomes P(X < K - 0.5)
P(X ≥ K) becomes P(X ≥ K - 0.5)
P(X > K) becomes P(X > K + 0.5)
P(X = K) becomes P(K - 0.5 ≤ X ≤ K + 0.5)
From the given question, Assume that we are to determine the probability that more than 635 Americans support the bill.
Then we use the > sign.
∴
P(X > K ) becomes P(X > K + 0.5)
P(X > 635) becomes P(X > 635 + 0.5)
⇒ P(X > 635.5) tot the right.
Right of X = 635.5
