Bruno‘s mother is eight more than twice his age. His father is three years older than his mother is. If all three members have lived a total of 94 years, how old is each family member?
Answer:
Bruno = 15 years
Mother = 8 + 2(15) = 38 years
Father = 38 + 3 = 41 years
Step-by-step explanation:
Given that :
Let
Bruno's age = x
Mothers age = 8 + 2x
Father's age = 8 + 2x + 3 = 2x + 11
x + 8 + 2x + 2x + 11 = 94
5x + 19 = 94
5x = 75
x = 75 /5
x = 15
Bruno = 15 years
Mother = 8 + 2(15) = 38 years
Father = 38 + 3 = 41 years

*Sorry I forgot how to do this, and please answer this correctly*
Answer:
32
Step-by-step explanation:
(n/2) − 10 = 6
Add 10 to both sides.
n/2 = 16
Multiply both sides by 2.
n = 32
Answer:
n=32
Step-by-step explanation:
n/2 - 10=6
add 10 on both side
n/2 +10-10=6+10
n/2=16
multiply both side by 2
n/2×2=16×2
n=32
Dillon pays x dollars to get a haircut. He gives the stylist a
20% tip. The expression representing his total cost is x +
0.2x.
Which expression is equivalent and why?
O A. (0.2) because the cost of the haircut can be factored out.
B. 1.02x because adding 20% to the cost of the haircut is the same
as multiplying the cost by 1.02.
C. 1.2x because adding 20% to the cost of the haircut is the same as
multiplying the cost by 1.2.
D. 1.2x because adding $20 to the haircut is the same as multiplying
the cost by 1.2.

Answer:
40+62+58+43+36+55+41+28+31+37+75+64= 570 people
Step-by-step explanation:
If you add all the no.of people who rode the bus, you will get the answer since the qn is 'how many' which refers to the number of people and 'rode the bus over the course of the day' which means throughout the day and as you said, the graph given above is number of passengers who rode bus throughout the day. Also, do not look at the time given, it is useless according to the question.
I hope it helps.
There are 570 people rode the bus over the course of the day.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
From the values on the graph which is presented in the table above, the number of people who rode the bus during the 12.00 hour is 55.
If we add all the no.of people who rode the bus, tjen we will get the answer since the qn is 'how many' which refers to the number of people and 'rode the bus over the course of the day' which means throughout the day
Since the graph given above is number of passengers who rode bus throughout the day.
Therefore, we have;
40+62+58+43+36+55+41+28+31+37+75+64= 570 people

D.
In the 4 months, the Taco Bus sold about 500,000 tacos in all.
E.
There were 22,157 tacos sold in May and June combined.
Part B
How many more tacos were sold in July than in May and August combined? Enter your answer in the box.
Answer:
Step-by-step explanation:
A: Correct
June + August > July
12,832 + 8,465 > 20,005
21,297 > 20,005
B: Wrong
July = June + 8,173
20,005 = 12,832 + 8,173
20,005 ≠ 21005
C: Correct
July + August > May + June
20,005 + 8,465 > 9,325 + 12,832
28470 > 22157
D: Wrong
9,325 +12,832 +20,005 + 8,465 = 50627
E: Correct
May + June = 22,157
9,325 + 12,832 = 22,157
22,157 = 22,157
Part B: 2215
July - May + August = ?
20,005 - 9,325 + 8,465 = ?
20,005 - 17790 = 2215

Katie feeds her cat, Elmer, 2/3 of a cup of food each day. She buys a bag of cat food that contains 18 cups of dry
food. How many days will that bag of cat food last?
Answer:
27
Step-by-step explanation:
Set up a proportion.
1 day / (2/3 cup) = x/ 18 cups Cross Multiply
1 day * 18 cups = 2/3 cup * x Multiply both sides by 3
1 day * 18 cups * 3 = 2x
54 day cups = 2x cups Divide by 2
54 day cups/2 cups = x
27 days (The cups cancel)
Answer:
27 days it will last

A fishing boat has snagged a fish and want to know the depth of the fish. If the there is
18 meters of fishing line out and the angle of depression is 24º, how deep is the fish?
Round the nearest tenth of a meter.
7.3 meters
Step-by-step explanation:
hypotenuse = 18
angle depression = 24 degrees
missing side = opposite, x
since this has opposite and the hypotenuse were going to use sin
sin(24 degrees) = .40673664307
multiply .40673664307 by the length (18) = 7.32125957526 rounded down =7.3 meters
The depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A fishing boat has snagged a fish and wants to know the depth of the fish. If there are 18 meters of fishing line out and the angle of depression is 24º
We can draw a right-angle triangle:
From the right-angle triangle:
Let x be the depth of the fish.
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying sin ratio:
sin24 = x/18
x = 18sin24
x = 7.32 meters ≈ 7.3 meters
Thus, the depth of the fish is 7.3 meters if the fishing boat has snagged a fish and wants to know the depth of the fish. If there is 18 meters of fishing line out and the angle of depression is 24º.
