Hannah wants to save 1/3 of her allowance each week to buy a new dress that costs $45.00. if her allowance is $6.00 each week, h

Bess [88]

Answer:

It will take 22.5 weeks for her to save up to buy the dress.

Step-by-step explanation:

1/3 of $6.00 is 2.

(6 ÷ 3 = 2)

So she's saving $2 each week.

Now we need to divide $45 by $2 to get the number of weeks.

45 ÷ 2 = 22.5

-34x+6=-28<br> I need to learn how to solve for x

Dimas [21]

Answer:

x=1

Step-by-step explanation:

-34x+6=-28

-6 -6

-34x=-34

-34 -34

x=1

Subtract 6 from both sides. on the left the 6 will be canceled out and on the right -28-6= -34

Than you divide -34 on both sides on the left the -34 will be canceled and on the right -34 divided bt-34 is positive 1. So x equals 1.

The part of a cylindrical soup can that is covered by the label is 8.5 cm tall and has a diameter of 6.5 cm. What is the area of

julia-pushkina [17]

Answer:

$180.4~cm^2$

Step-by-step explanation:

<u>Surface Area</u>

The surface area of a cylinder of height h and radius r is given by:

$A=2\pi rh$

It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:

$A=2\pi rh+2\pi r^2$

The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.

Now we calculate the side area of the can:

$A=2\pi (3.25)(8.5)$

$A=173.6~cm^2$

We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:

$A_o= 0.8*8.5=6.8~cm^2$

The total area of the label is:

$A=173.6~cm^2+6.8~cm^2=180.4~cm^2$

The area of the label is $\mathbf{180.4~cm^2}$
