Answer:

The simple interest is $30

Step-by-step explanation:

To find this, we use the simple interest formula

Mathematically, this is;

I = PRT/100

P is the principal = $200

R is the rate = 5%

T is the time = 3 years

Substituting these values, we have;

I = (200 * 5 * 3)/100

I = $30

Answer:

Rs 877.2

Step-by-step explanation:

The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is Rs 6 per Square Foot?

The iron box is shaped as a rectangular prism

The formula for the surface area of a rectangular prism is given as:

S = 2(lw + lh + wh)

L = Length = 9ft

W = Width = 4.4ft

H = Height = 2.5 ft

Hence:

Surface area = 2[(9 × 4.4) + (9 × 2.5) +(4.4 × 2.5)]

Surface area = 2[(39.6) + (22.5) + (11)]

Surface area = 2[73.1]

Surface area = 146.2 ft²

From the question:

The cost of the sheet is Rs 6 per Square Foot

1 ft² = Rs 6

146.2 ft² = x

Cross Multiply

x = 146.2 × Rs 6

x = Rs 877.2

The cost of the iron sheet used to make the box is Rs 877.2

Step-by-step explanation:

Answer:

x = 23 ; y = 15

Step-by-step explanation:

Given :

Let the numbers be : x and y

x + y = 38 - - (1)

x = y + 8 - - - (1)

Put x = y + 8 into (1)

y + 8 + y = 38

2y + 8 = 38

2y = 38 - 8

2y = 30

y = 30/2

y = 15

x = y + 8

x = 15 + 8

x = 23

Step-by-step explanation:

using trignometry,

tan 60 = 3√3/x=√3

→x=3

cos 30 =3√3/y=√3/2

→y=6

Answer:

x+y

Step-by-step explanation:

It is x+y because if you look at (x-y) and (y-x) they can cancel with each other since x- x and -y+y. All that's left is x+y

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

288 Cubic Inches

Step-by-step explanation:

Assuming the cereal takes up 80% of the total volume of the box, you would take 80% of the total volume.

First, do Base x Width x Height for the volume of the box.

10 inches x 3 inches x 1 foot      (1 foot is 12 inches)

10 x 3 x 12 = 360

Now, take 80% of 360 cubic inches.

80% is 0.8 times a number

0.8 x 360 = 288

288 Cubic Inches

Answer:

25 hours per week

Step-by-step explanation:

Step one:

given data

Suri makes $15 per hour and gets a weekly bonus of $25

Juan makes $14 per hour and gets a weekly bonus of $50.

Let the number of hours worked be x

and let the total earned be y

For Surl

The expression for the total is

y= 25+15x-----------1

For Juan

The expression for the total is

y= 50+14x-----------2

Step two:

Equate the two expressions we have

25+15x=50+14x

collect like terms we have

25-50= 14x-15x

-25= -x

x= 25

Yes its is possible that they earned the same amount if they work for 25 hours

Answer:

66 inch ^3

Step-by-step explanation:

The volume of a rectangular prism is LxWxH. So 11x2x3= 66 inches.

Answer:

its 3/12 ×180 which is 1/4 of 180 as similar which is = 45. So we find out that 45 members where involved last year in youth soccer league.

Answer:

12/15

Step-by-step explanation:

Answer:

All real numbers

Step-by-step explanation:

x² + 16x + 64 is a parabola that opens up, when graphed.

This means it will have a U shape that will infinitely extend outwards in both directions, across the x axis.

So, the domain will include all real numbers.

[tex]A=2x^2+18x+36[/tex]

Step-by-step explanation:

Quadratic Function

It's given the length of a rectangular park is twice its width.

Let's call:

x = width of the rectangular park

2x = length of the rectangular park

The park is surrounded by a 3-foot-wide path. This path adds 3 ft twice to both dimensions, i.e.:

x+3+3=x+6 width of the park and the path

2x+3+3=2x+6 length of the park and the path

The total area is:

A=(x+6)(2x+6)

Operating:

[tex]A=2x^2+6x+12x+36[/tex]

[tex]\boxed{A=2x^2+18x+36}[/tex]

Answer:

Answer: D

Step-by-step explanation:

1.88 in the equation is the rate of change.

rate of change means, "the speed at which a variable changes over a specific period of time."

L = the length of his femur. every time the femur grows an inch, the height also increases according to the equation.

an example is when the femur is 19 inches.

H = 1.88(19) + 32.01

H = 67.73

The height of the man is 67.72 inches if his femur was 19 inches.
