Brandon made 80 cups of lemonade for his party. At the party, 10 cups of lemonade are finished eac hour. How many hours will Brandon's lemonade last?
Answer:
8 hours
Step-by-step explanation:
let number of hours it takes to finish the cup be t,
we know that we have 80 cups, and we know we can finish 10 cups per hour so,
10t = 80 which is 10 times t = 80
Solve for t,
10t/10 = 80/10
t = 8
In 2019, the New England Patriots played 16 football games. The ratio of the number of games they won to the the number of games they lost was 3/1. How many games did they win? How many games did they lose?
Answer:
New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.
Step-by-step explanation:
The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose the number of games they won is W and the number of games they lost is L.
As per the given
Total games L + W = 16
Ratio W/L = 3/1
W = 3L
L + 3L = 16
4L = 16
L = 4
And, W = 3 x 4 = 12
Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".

Answer:
It would take alot of time for be to fill everything out so the simple solution is, complementary angles add up to 90 degrees and supplementary add up to 180 degrees. Simply for complementary do 90 - m<1 = m<2, and for supplementary 180 - m<3 = m<4.
Which of the following is equivalent to the equation 3x – 2y = –8?
1. y = 11/2x
2. y = -3x+4
3. y = 3/2x + 4
4. - 3/2x - 4
Answer:
3/2x + 4
Step-by-step explanation:
3x - 2y = -8
-2y = -8 - 3x
y = 4 + 3/2x
Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 17 pennies, 12 dimes, and 26 quarters. The rest of the coins are nickels. There are 66 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
_____ of the coins are not nickels.
Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11
NEED HELP ASAP plzzz
Answer:
x = 40
Step-by-step explanation:
∠D = ∠ADB + ∠BDC
= 30 + 40
= 70°
In ΔBDC,
BD = CD
∠DBC = ∠DCB {angles opposite to equal sides are equal}
∠DBC + ∠DCB + ∠BDC = 180 {Angle sum property}
2∠DCB + 40 = 180
2∠DCB = 180 -40
2∠DCB = 140
∠DCB= 140/2
∠DCB = 70°
In ΔADC,
x + ∠D + ∠C = 180
x + 70 + 70 = 180
x + 140 = 180
x = 180 - 140
x = 40°
In a pair of complementary angles, the measure of the larger angle is twice that of the smaller
angle. What is the measure of the larger angle?
A 30°
B 60°
C 90°
D 120°
Answer:
D. 120°
Step-by-step explanation:
Complementary angles have a sum of 180 and since its twice the measure of the smaller one so the smaller one would have to be 60 in order for the bigger one to be 120 because you then add your two angles and it should make 180
Answer:
Step-by-step explanation:
Supplementary angles sum to 90. We are told the larger angle is twice the smaller.
L=2S, S=L/2
S+L=90, using S=L/2 we have
L/2+L=90
(3L)/2=90
3L=180
L=60

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Answer:
golden corral equation y=1.5x+15
western sizzlin equation y=2.5x+13
yes they are linear because if you were to graph them they would have a straight line and they would go upwards because the slope is positive
For which one you would pick would depend on how much you drink. If you drink a lot you should probably go to golden corral but if you dont drink that much then western sizzlin is probably the best choice.

In the figure, AB || CD. If m<1=70° and m<2 = 45°, find the m<3
Answer:65 degrees
Step-by-step explanation: a triangle has 180 degrees.
one angle is 45 degrees and the other is 70
if we add them together we get 115
180-115 is 65
m3 is 65 degrees
A ABC is isosceles. Find AC.
Please help): I’m not good at geometry
Answer:
x = 5
Step-by-step explanation:
As it is an isosceles triangle so two sides BA and BC are equal. So,
BA = BC
3x + 3 = 2x + 8
3x - 2x = 8 - 3
x = 5
Therefore AC = 5
Susie's dog is 2feet tall. When she measures her dog in inches he was 24 inches. Why is there an increase in inches
Given:
Susie's dog is 2 feet tall. When she measures her dog in inches he was 24 inches.
To find:
Why is there an increase in inches.
Solution:
It is given that Susie's dog is 2 feet tall.
We know that,
1 feet = 12 inches
Using this conversion, we get
2 feet = 2×12 inches
2 feet = 24 inches
So, the measures 2 feet and 24 inches are equal.
Therefore, if Susie's dog is 2 feet tall then he is 24 inches tall because both of these measure are equal.

Family spends $240 per week on food. If this is %16 of their income, what is the family's weekly income?
Answer: The family's weekly income is $1500
-------------------------------------------
Work Shown:
x = weekly income (in dollars)
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500
Pls Mark as brainliest
Answer:
1500
Step-by-step explanation:
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500
