Word problem - Jose played soccer for 5 hours every afternoon for 8 days. How many hours did Jose play soccer in all?
So this problem is about Jose and the amount of time he spends playing soccer.
Next, let's pick out what we know and what we want to find out.
We know that Jose played soccer for 5 hours every afternoon for 8 days. We want to find out how many hours of soccer he played in all so we need to multiply.
We multiply the amount of time he spent playing soccer each afternoon which is 5 hours by the number of days which is 8 days.
(8) (5) = 40
This means that Jose played 40 hours of soccer in all.
If a certain brand of icecream is 99% fat free, how many cups would you have to eat to ingest the same amount of fat that would be in 1 cup of regular icecream?
Answer:
10,000 cups
Step-by-step explanation:
Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2
Let's suppose a cup of regular ice cream would have 100 parts of fat.
The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.
If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it
These numbers won't change if we used another number instead of 100 in the example shown.
Two similar FOR SALE signs have a scale factor of 5:3. The largest sign’s perimeter is 60 inches. Find the small sign’s perimeter.
The small sign's perimeter is 36 inches
Step-by-step explanation:
The scale factor between two figures is obtained by:
[tex]Scale = \frac{P_{l}}{P_{s}}[/tex]
So,
We know that
[tex]Scale= 5:3\\P_l = 60\ in\\[/tex]
Putting the values in the above equation of scale factor we get
[tex]\frac{5}{3} = \frac{60}{P_s}[/tex]
Cross multiplication
[tex]5 * P_s = 60*3\\5P_s = 180[/tex]
Dividing both sides by 5
[tex]\frac{5P_s}{5} = \frac{180}{5}\\P_s = 36[/tex]
Hence,
The small sign's perimeter is 36 inches

16 factory workers made 40 pieces in a certain amount of time.
a)Do these quantities (number of workers and number of pieces produced) vary directly or inversely?
b)Find the constant of variation.
a) The quantities vary directly
b) The constant of variation is 2.5
Step-by-step explanation:
Lets us revise the direct and inverse variation
If y varies x directly, then y = kx, that means the ratio between them is constant ( [tex]\frac{y}{x}=k[/tex] ) , they increased together and decreased together, k is the constant of variationIf y varies x inversely, then yx = k, that means when x increased y must be decrease ( [tex]y=\frac{k}{x}[/tex] ) k is the constant of variation∵ 16 factory workers made 40 pieces in a certain amount of time
- If the number of worker increased, then the number of pieces
increased in the same certain time, if the number of worker
decreased, then the number of pieces also decrease in the
same certain time
∴ The the number of workers and the number of pieces produce
vary directly
∴ Number of pieces produced = k × number of worker
a) The quantities vary directly
∵ The number of worker = 16
∵ The number of pieces produced = 40
- Substitute these values in the equation of variation above
∴ 40 = k × 16
- Divide both sides by 16
∴ k = 2.5
b) The constant of variation is 2.5

maxwell wants a new phone for his 25th birthday. the one he wants cost $860 to purchaseand an additional 75 a month. his parents are willing to pay for half of the cost of the phone as a birthday gift present as long as maxwell pays the other half and the monthly charge . how much will maxwell spend after 5 month's
Answer:
805
Step-by-step explanation:
First we need to find half of 860
860÷2=430 because the parents are paying for tht
the other 430 he has to pay .
there is an additional charge of 75 dollars every month for 5 months .
75×5=375
now we need to add up his half 430 & the monthly fees for 5 months 375
430 +375=805
In △ABC, point P∈AB so that AP:BP=1:2. Point R ∈ PB that PR:BR=1:2. Point Q∈BC so angle BQR = angle BCP. Find ratio of PQC to ABC.
Answer:
Ratio of PQC to ABC is 2:9.
Step-by-step explanation:
In ΔBRQ and ΔBPC
∠BQR = ∠BCP (given) and ∠B is common for both triangles, so from AAA similarity ΔBRQ and ΔBPC are similar.
⇒ BQ : QC = BR : RP = 2 : 1 →(1)
now draw perpendiculars from points A and P to BC line segment. Call the projected points as A' and P'.
It is clear that lines AA' and PP' are parallel. So in ΔBPP' and ΔBAA' we have AAA similarity with common angle at B.
⇒PP' : AA' = BP : BA = 2 : 3 →(2) (∵ AP : PB = 1 : 2)
area of ΔPQC = 0.5×PP'×QC
area of ΔABC = 0.5×AA'×BC
area of ΔPQC : area of ΔABC = (0.5×PP'×QC)/(0.5×AA'×BC)
=(PP'/AA')×(QC/BC)
=(2/3)×(1/3) (∵ from (1) and (2))
=2/9.
∴ Ratio of PQC to ABC is 2:9

Point M is located at (-6, 6) What is located 5 units from point M
The points located 5 units from the point M (-6, 6) are (-1, 6), (-11, 6), (-6, 11) and (-6, 1).
To find a point located 5 units from point M in any direction, you can use the coordinates of point M and adjust them based on the distance.
If point M is located at (-6, 6), and you want a point 5 units away, you can choose a direction (left, right, up, or down) and adjust the coordinates accordingly.
For example, if you want a point 5 units to the right of M, you add 5 to the x-coordinate:
[tex]x_{new[/tex] = -6 + 5 = -1
So, a point located 5 units to the right of M is (-1, 6).
If you want a point 5 units to the left of M, you subtract 5 from the x-coordinate:
[tex]x_{new[/tex] = -6 - 5 = -11
So, a point located 5 units to the left of M is (-11, 6).
Similarly, the y-coordinate can be modified for points 5 units above or below M.
For example, if you want a point 5 units to the top of M, you add 5 to the y-coordinate:
[tex]y_{new[/tex] = 6 + 5 = 11
So, a point located 5 units to the top of M is (-6, 11).
If you want a point 5 units to the bottom of M, you subtract 5 from the y-coordinate:
[tex]y_{new[/tex] = 6 - 5 = 1
So, a point located 5 units to the bottom of M is (-6, 1).

• What is the solution to 5x+ 20 = 7(x+2)?
For this case we must find the solution of the following equation:
[tex]5x + 20 = 7 (x + 2)[/tex]
Applying distributive property on the right side of the equation we have:
[tex]5x + 20 = 7x + 14[/tex]
Subtracting 7x from both sides of the equation:
[tex]5x-7x + 20 = 14\\-2x + 20 = 14[/tex]
Subtracting 20 from both sides of the equation:
[tex]-2x = 14-20[/tex]
Different signs are subtracted and the major sign is placed.
[tex]-2x = -6[/tex]
Dividing between -2 on both sides of the equation:
[tex]x = \frac {-6} {- 2}\\x = 3[/tex]
Thus, the solution of the equation is[tex]x = 3[/tex]
Answer:
[tex]x = 3[/tex]

the relationship between time and the distance remaining on a 3 mile walk at a steady rate of 2 miles per hour
Answer:
The Time taken to cover the distance of 3 miles at the speed of 2 miles per hour is 1.5 hours
Step-by-step explanation:
Given as :
The distance cover while walking = 3 miles
The Speed with which it walk 3 miles = 2 miles per hour
Let the time taken to cover the distance = T hours
Now,
∵ Time = [tex]\dfrac{\textrm Distance}{\textrm Speed}[/tex]
Or, T = [tex]\dfrac{\textrm 3}{\textrm 2}[/tex]
∴ T = 1.5 hours
So, time taken is 1.5 hours
Hence The Time taken to cover the distance of 3 miles at the speed of 2 miles per hour is 1.5 hours Answer

24. Jack's mother is 44 years old. She is 4 years older than 8 times Jack's age. The
equation 8a + 4 = 44 represents this situation.
How old is Jack?
A. 5
B. 6
c. 9
d.13
Answer:
Jack is five. so, it's A
Step-by-step explanation:
subtract 4 from both sides of the equation. You can cancel out the four on the left, and get 40 on the right (since you took four away from 44.)
Then, divide by 8 on both sides. The eight is canceled out on the left. eight goes into 40 five times, meaning a=5.
The correct option is (A) 5. To find Jack's age, subtract 4 from both sides of the equation 8a + 4 = 44 and then divide by 8. This results in a = 5, meaning Jack is 5 years old.
To solve the given equation, 8a + 4 = 44, for Jack's age, we first need to isolate the variable a, which represents Jack's age. This can be done by first subtracting 4 from both sides of the equation to undo the addition.
8a + 4 - 4 = 44 - 4
8a = 40
Next, we divide both sides of the equation by 8 to undo the multiplication and solve for a:
8a / 8 = 40 / 8
a = 5
Therefore, Jack's age is 5 years old, which corresponds to option A.
