Answer:

5.58*10^7

Step-by-step explanation:

Recall that 10^a*10^b = 10^(a+b).  Thus, 10^5*10^2 = 10^7.

Thus, (1.8 x 10^5)(3.1 x 10^2) = (1.8)(3.1)*10^7 = 5.58*10^7

Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could
Lana71 [14]

Answer:

A, D, and E

Step-by-step explanation:

The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.

For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A

Write the equation for the line that is parallel to y=2/3x-5 and goes through the point (-12/2)
tatyana61 [14]

Answer:

I put the equation into Point-Slope Form and got:

y - 2 = 2/3(x + (-12))

Distribute the 3 to the numbers on the left:

3y - 6 = 2(x - 12)

Multiply the Parenthesis by 2:

3y - 6 = 2x - 24

Add 6 to the right side:

3y = 2x - 18

Divide both sides by 3:

y = 2/3x - 6 is the answer :)

What is the solution for the equation 4x - 10 = 2x?<br> Ox=5<br> Ox=4<br> Ox=1<br> Ox= -1.67
Akimi4 [234]

Answer:

5

Step-by-step explanation:

4x-10=2x            - Original equation

4x=2x+10           - Move constant to the right-hand side and change its sign

4x-2x=10            - Move variable to the left-hand side and change its sign

2x=10                 - Combine like terms and divide both sides by 2

x=5                     - Answer

Hope this helps!!!
