Answer:
128calories/cup
256calories
Step-by-step explanation:
Given parameters:
Amount of calories = 96calories
Number of cups = [tex]\frac{3}{4}[/tex]cups
Unknown:
Unit rate(calories per cup) = ?
Number of calories in 2 cups = ?
Solution:
A. To find the unit rate;
Unit rate = [tex]\frac{amount of calories}{number of cups}[/tex]
Insert the parameters and solve;
Unit rate = [tex]\frac{96}{\frac{3}{4} }[/tex]
Unit rate = 96 x [tex]\frac{4}{3}[/tex] = 128calories/cup
B. Number of calories in 2 cups;
Amount of calories = unit rate x number of cups
Amount of calories = 128calories/cup x 2cups
Amount of calories = 256calories

a popular roller coaster ride lasts 10 minutes. there are 20 people on average on the roller coaster during peak time. how many people are stepping into the roller coaster
Answer:
Flow rate is 2 people per minute
Step-by-step explanation:
The computation of the number of people stepping into the roller coaster is shown below:
Here we use the little law
As we know that
Inventory or number of jobs = throughput or flow rate × flow time
20 = throughput or flow rate × 10
Therefore
Flow rate is 2 people per minute
We simply applied the above formula
What is the slope of a line parallel to the line y = 4x – 11?
simplify (q+8)2 please help, thank you
q^2 +16q+64
All you have to do is substitute the exponent two.
Q by itself is q squared: q^2
Q times 8 is 8q, and because of exponent you have to double it, which gives you 16q.
And 8 times itself is 64.
Hope this helps

Help me with this question pleaseeee
What is m∠PTS? Enter your answer in the box. ° A horizontal line segment S R intersects with line segment P Q at their midpoint T. The upward-left and downward-right angles made by these lines are acute. The upward-left acute angle is labeled left square bracket 11 left parenthesis y minus 10 right parenthesis right square bracket degrees. The downward-right acute angle is labeled left parenthesis 4 y minus 5 right parenthesis degrees.
Answer:
m /_PTS = 55°
Step-by-step explanation:
Just took the quiz..
The measure of angle m∠PTS from the given figure is 55°.
From the given figure, the two angles are 11(y-10)° and (4y-5)°.
What is vertical angle theorem?Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
Now, 11(y-10)° = (4y-5)°
⇒ 11y-110 = 4y-5
⇒ 11y-4y = -5+110
⇒ 7y = 105
⇒ y = 15
So, m∠PTS = 11(15-10)
= 55°
Therefore, the measure of angle m∠PTS from the given figure is 55°.

Please help me idk what to do *GEOMETRY finding angles*
Answer:
69
Step-by-step explanation:
First, find the angle FCB by subtracting 70 and 41 from 180. You should get 69. Then, because it says AD paralell EG, you could use the transversal FC to locate some angles. Fortunately, GFC and FCB are opposite interior angles, meaning they are equal in angle measure.

(x+92) =5xº
Answer:
X=23
Step-by-step explanation:
First you write the problem without the parenthesis so it's more easier to work out.
Second you need to do is change what is at the end of the problem all the way to beginning of the problem and also change the sign which should look something like this, x=5x-92.
Then you collect like terms which is ( 5x and x)
and sense x is 1 you subtract it and it would give you this -4x=-92. Divide both sides by 4 which would give you 23.

Step-by-step explanation:
The management of a forestry company estimates that acres of forest available for logging will increase at a rate given by R(t) = 56/root t + 7 for 0 leq t leq 20, where R(t) is the rate of new acreage becoming available in thousands of acres per year, t years after the current year. How many acres of forest, Q(t), will become available for logging over the first five years?
A. 46 thousand acres.
B. 148 thousand acres.
C. 296 thousand acres.
D. 92 thousand acres.
Answer:
Step-by-step explanation:
If the acres of forest available for logging will increase at a rate given by
R(t) = 56/√t + 7
In order to determine the acre of forest that become available after 5 years, we will substitute t = 5 into the formula.
R(5) = 56/√5 + 7
R(5) = 56/2.236 + 7
R(5) = 25.044 + 7
R(5) = 32.044
The amount that will be available over the first five years is 32 thousand acres
Determine the probability that it will not rain for the next two weeks. Express your answer as a decimal precise to two decimal places.
Answer:
Probability of not raining in next two weeks is 0.696
Step-by-step explanation:
Let us calculate -
Probability diagram is attached below .
Probability of not raining in next week is 0.8
Probability of not raining in second week is 0.87
Therefore, Probability of not raining in next two weeks = [tex]0.8\times 0.87[/tex]
= 0.696
Thus , the probability is 0.696

Jimmy is buying balloons and party hats for his little sister’s birthday party. The party store charges $1.50 for each bag of balloons and $6.00 for each package of hats. Which of the following equations could be used to determine different combinations of b bags of balloons and h packages of party hats that he could buy for a total of $24 ?
Answer:
4 bags of balloons and 3 bags of party hats
Step-by-step explanation:
1.50 x 4= 6
6 x 3= 18
6+18=24
The equation that could be used to determine different combinations will be 4b + 3h.
Based on the information given, the party store charges $1.50 for each bag of balloons and $6.00 for each package of hats.
Therefore, the equation that fits the explanation will be: 4b + 3h.
= 4b + 3h.
= 4(1.50) + 3(6)
= 6 + 18
= 24.
Therefore, the equation is 4b + 3h.
