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.

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

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.

I'm pretty sure this is the right answer..

Answer:

Y=114 X=54

Step-by-step explanation:

Y and 114 are the same and the Top line is 180 degrees because it is straight so you can add 114 + 12= 126 which leaves 54 for X

Answer

y = 10

Step-by-step explanation:

if they are both negative they cancel each other out so -10 x -1 are both negative it would be 10 so y = 10

please mark brainly

Answer:

30 cm

Step-by-step explanation:

A. Multiply daily rate by number of days and add that to the starting height:

Height = 2d + 8

B. Set height to 20 and solve for d:

20 = 2d +8

Subtract 8 from both sides

12 = 2d

Divide both sides by 2

D = 6

It wall take 6 days.

Answer: See explanation

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:

-16/7

Step-by-step explanation:

3(x-2) + 4x = 10(x + 1)

3x-6+4x=10x+10

3x+4x-10x=10+6

-7x=16

X=-16/7

So the answer is -16/7

Answer:

it's -16/3

Step-by-step explanation:

got it right on edge

Answer:

a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881

b) (2.5)2+2.5×1.4+(1.4)2=31.5

Step-by-step explanation:

yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4

15.625-2.744=12.881.

b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please

(2.5)2+2.5×1.4+(1.4)2

5+2.5×1.4+2.8

7.5×4.2=31.5

Answer:

Answer:

$1,360

Step-by-step explanation:

Take the monthly payment of $50 and multiply it by 12 because there is 12 months in a year which is $600. Next subtract $2,600 by your deduction of $300 which is $2,300. Then multiply by 20% because the insurance pays 80% leaving you with 20%, you get $460. Add $460 and $300 because those are the amounts you paid and you get $760. Now add the $600 to the $760 because of the monthly payment. The total comes out to $1,360.

Answer:

Step-by-step explanation:

Answer:

Your answer is A 1/2

Step-by-step explanation:

if we know that y=mx+b and that m is the slope and also that m = rise over run then we see that the rise of this line is 1 and that the run  2.

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

Given :

Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.

To Find :

Which measurement is in pounds, and which is in kilograms.

Solution :

We know, mass in kg and pounds are related as :

[tex]m_P = 2.2m_{kg}[/tex]

Putting, [tex]m_{kg}=38[/tex] and [tex]m_P=84[/tex] , we get :

LHS = 84

RHS = 2.2 × 38 = 83.6 ≈ 84

Since, LHS = RHS .

Therefore, 38 units is Kg and 84 units in Pounds.

Hence, this is the required solution.
