A cuboid with a volume of 925cm^3 has dimensions.
4cm, (x + 1) cm and (x + 11) cm.
Show clearly that x^2 + 12x - 220 = 0
Solve the equation by factorising, making sure you show the factorisation.
State both values of x on the same line.
Finally, find the dimensions of the cuboid, writing all three on one line.

Answers

Answer 1

Answer:

Step-by-step explanation:

Volume of the cuboid = Length * Width * Height

Given

Length = 4cm

Width = (x+1)cm

Height = (x-11)cm

Volume of the cuboid = 4(x+1)(x+11)

Volume of the cuboid = 4(x^2+11x+x+11)

Volume of the cuboid = 4(x^2+12x+11)

Volume of the cuboid = 4x*2+48x+44

925 = 4x*2+48x+44

4x*2+48x+44-925 = 0

4x*2+48x-881 = 0

Divide through by 4

x^2 + 12x - 220.25 = 0

Factorize using the general formula;

x = -12±√12²-4(-220.25)/2

x = -12±√144+881/2

x = -12±√1025/2

x = -12±32/2

x = 12+32/2

x = 20/2

x = 10

Hence the dimension of the cuboid is 4cm, (10+1)cm and (10+11)cm

Dimension is 4cm by 11cm by 21cm

Nora read 1/9 of a book on Monday and 2/5 on Tuesday. What fraction of the book does she have left to read

Answers

Answer:

Step-by-step explanation:

On Monday, Nora read ¼ of the book, therefore she is left with ¾ of the original book.

Then on Tuesday, she read 2/5 of what was left on Monday therefore she is left with 3/5 of ¾ of the original book. This is equal to:

(3/5) (3/4) = 9/20

She still needs to read 9/20 of the book or 0.45 or 45% of the book.

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.

Answers

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.

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?

Answers

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

Part B
How many more tacos were sold in July than in May and August combined? Enter your answer in the box.

Answers

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

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.
