Answer:

Step-by-step explanation:

Step one:

given

height h= 1m

diameter= 70cm= 0.7m

radius r= d/2= 0.7/2= 0.35m

The surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.

The formula is

T.S.A.=2πrh+2πr^2

Required is the T.S.A

Step two:

substitute our given data we have

T.S.A.=2*3.142*0.35*1+2*3.142*0.35^2

T.S.A.=2.199+0.769

T.S.A.=2.96m^2

T.S.A.=3m^2 approx.

Step-by-step explanation:

Your question isn't really clear. Let me help you rephrase it and solve.

Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.

The total hours that Cesar has used in practicing will be:

= 1 1/2 + 2 1/4 + 1 1/2

= 5 1/4

To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:

= 10 - 5 1/4

= 4 3/4 hours.

Cesar needs to practice for 4 3/4 hours more.

Answer:

[tex]1.872 \times {10}^{13} [/tex]

Step-by-step explanation:

Simply multiple the values listed

[tex]3.12 \times {10}^{5} \\ \times 6 \times {10}^{7} [/tex]

You can just multiply the values and keep it in scientific notation. No reason to multiply all if it to find the answer.

[tex]18.72 \times {10}^{12} [/tex]

Now we have to put it into scientific notation, simply move the decimal to the left by 1 and add to the exponenet by 1.

Answer:

Option (3)

Step-by-step explanation:

Length of the given rectangle = (x + 6) meters

Width of the given rectangle = (2x - 1) meters

Area of a rectangle = Length × Width

                                = (x + 6)(2x - 1)

                                = x(2x - 1) + 6(2x - 1)

                                = 2x² - x + 12x - 6

                                = (2x² + 11x - 6) square meters

Therefore, area of the given rectangle is defined by the expression given in option (3).

Answer:

x= -27 y=18

Step-by-step explanation:

plug in zero for x to find y and plug in zero for y to find x

Answer:  The x-intercept is (-27,0)

The y intercept is (0,18)

Step-by-step explanation:

For the x- intercept, Substitute 0 for y and solve for x

-2x + 3(0) = 54

-2x + 0 = 54

x = 54/-2

x = -27

For the y -intercept, Substitute 0 for x and solve for y

-2(0) + 3y = 54

0 + 3y = 54

y = 54/3

y = 18

[tex]40 + 4x = 180[/tex]

[tex]4x = 180 - 40[/tex]

[tex]4x = 140[/tex]

[tex]x = \frac{140}{4} [/tex]

Step-by-step explanation:

The radius of the moon in Kilometers is 1350 km.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.

Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,

1 km = 1000m

1 m = 1 / 1000 km

1350000 meters = 1350000 / 1000 km

1350000 meters = 1350 km

First, we need to determine an equation for both Arcade X and Arcade Y.

Arcade X: 0.65t + 5 = P

Arcade Y: 0.45t + 10 = P

If you graph both lines, we will find the solution to be (25, 21.25), which means that D. 25 tokens will need to be bought in order for the total cost in both arcades to be the same.
