What is the area of a rectangle with length 4 cm and width 12 cm?
16 cm2
48 cm2
3 cm2
32 cm2​

Answers

Answer 1

Answer:

option 2 = 48 cm ²

12 × 4 = 48

cm × cm = cm²

answer = 48 cm²

Answer 2
The answer is 48 cm because area=LxW so that means that you have to multiply 4 cm and 12 cm so 4x12=48

The classrooms in the Oakhurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are need to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary?

Answers

Answer:

189 gallons

Step-by-step explanation:

7 gallons for 3 classrooms, so 7/3 for 1 classroom

multiply 7/3 * 129 to get 301 gallons at North High School

multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary

301 - 112 = 189 gallons more at North High School than at Edgewater Elementary

The more gallons should be 189 gallons

The calculation is as follows:

7 gallons for 3 classrooms, so 7 by 3 for 1 classroom

Now  

we have to multiply 7 by 3 with 129 so that 301 gallons at North High School could come

Now  

multiply 7 by 3 with 48 to get 112 gallons at Edgewater Elementary

Now

=  301 - 112

= 189 gallons more

11. A car is travelling at the average speed of 50 km/hr. How much distance would it travel in
1 hour 12 minutes?

Answers

Answer: Twelve minutes is 12/60 = 1/5 = 0.2 hours. So the car travelled for 1.2 hours. The car travelled at an average of 50 km/hr for 1.2 hours, so it travelled 50 km/hr * 1.2 hours = 60 km.

Aldo the trainer has two solo workout plans that he offers his clients: plan a and plan b. Each client does either one or the other (not both). On friday there 8 were clients who did plan a and 3 who did plan b. On saturday there were 3 clients who did plan a and 5 who did plan b. Aldo trained his friday clients for a total of 7 hours and his saturday clients for a total of 6 hours. How long does each of the workout plans last?

Answers

Answer:

x = number of hours to train plan a clients

x = 0.55 hour

y = number of hours to train plan b clients

y = 0.87 hours

Step-by-step explanation:

Friday

Plan a = 8 clients

Plan b = 3 clients

Total hours = 7

Saturday

Plan a = 3 clients

Plan b = 5 clients

Total hours = 6

Let

x = number of hours to train plan a clients

y = number of hours to train plan b clients

8x + 3y = 7 (1)

3x + 5y = 6 (2)

Multiply (1) by 5 and (2) by (3)

40x + 15y = 35 (3)

9x + 15y = 18 (4)

Subtract (4) from (3)

40x - 9x = 35 - 18

31x = 17

Divide both sides by 31

x = 17 / 31

= 0.548 hour

Approximately

x = 0.55 hour

Substitute x = 0.55 hour into (1)

8x + 3y = 7

8(.55) + 3y = 7

4.4 + 3y = 7

3y = 7 - 4.4

3y = 2.6

Divide both sides by 3

y = 2.6 / 3

= 0.867 hours

Approximately

y = 0.87 hours

x = number of hours to train plan a clients

x = 0.55 hour

y = number of hours to train plan b clients

y = 0.87 hours

1.5x + 4.5y = 18. Where does the graph intersect the y-axis?

Answers

Answer:

4

Step-by-step explanation:

Substitute x for 0 and solve.

1.5(0)+4.5y=18

4.5y=18

y=4

For the equation, 1.5x + 4.5y = 18 at x = 0 the graph will intersect at 4 of y -the axis.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the equation is 1.5x + 4.5y = 18. For the value of y substitute x for 0 and solve.

1.5x + 4.5y = 18

1.5(0)+4.5y=18

4.5y=18

y=4

The value of y is equal to 4 means that the graph will intersect the y-axis at 4.

the position of a deep sea probe is -2 3/4 fathoms relative to the sea level. after finishing taking data, it moves to -2 5/8 fathoms relative to sea level. which was deeper, the first mission, or the second. (i’m in modern high school which means i get collage questions, i only have 1 hour left to get this done, someone help!)

Answers

Answer:

The first mission

Step-by-step explanation:

The depth readings are

The first mission:  - 2 3/4 fathomsThe second mission: - 2 5/8 fathoms

Comparing the readings

- 2 3/4 = - 2 6/8  and  - 2 5/8

Absolute values compared

2 6/8 > 2 5/8

Indicating the greater value on the first mission

As per above, the first mission was deeper

As OP bisects ∠AOR, ∠AOP = ∠POR = 55°

So, ∠AOR = ∠AOP + ∠POR = 55° + 55° = 110°

As OS bisects ∠ROB, ∠ROS = ∠SOB = x

As total angle on a line is 180°,

110° + x + x = 180°

=> 2x = 70

=> x = 35°

∠POS = ∠POR + ∠ROS = 55° + x = 55° + 35°

=> ∠POS = 90°

It is E because you should multiply 55 by 2

Hana rents a car for a day. Her car rental company charges $50 per day and $0.40 per mile. Peter rents a car from a different company that charges $70 per day and $0.30 per mile. How many miles do they have to drive before Hana and Peter pay the same price for the rental for the same number of miles?

Answers

50 + .4x = 70 + .3x

.4x = .3x + 20

.1x = 20

x = 200

Let x be the number of miles.

They have to drive 200 miles.

They will drive 200 miles before paying same amount.

Let the number of miles that they will drive together and pay the same amount be represented by x.

Since Hana's car rental company charges $50 per day and then $0.40 per mile, this can be represented as:

= 50 + (0.40 × x)

= 50 + 0.40x

Since Peter rents a car from a different company that charges $70 per day and then $0.30 per mile, this will be:

= 70 + (0.30 × x)

= 70 + 0.30x

Then we will equate both Hana's and Peter's equation together and this will be:

50 + 0.40x = 70 + 0.30x

Collect like terms

0.40x - 0.30x = 70 - 50

0.1x = 20

x = 20/0.1

x = 200

In conclusion, they will drive 200 miles before paying thesame amount
