Maggie stacked a box that was 83 centimeters (cm) tall on top of a box that was 128 centimeters. How tall was the stack of boxes in meters and centimeters?

Answers

Answer:

211 centimeter ; 2.11 meter

Step-by-step explanation:

Given that:

Height of box 1 = 128 cm

Height of box 2 = 83 cm

Stacking box 2 on the box 1 :

Height of stack :

Height of box 1 + height of box 2

128 cm + 83 cm = 211 cm

Converting 211 cm to meter :

100 cm = 1 m

211 cm = (211 / 100) m

= 2.11 meter

Lucy separates a number of paintbrushes, x, into 2 equally sized groups. She claims that this is the same as making a group 1/2 the size of his original group. Create an equation that models Lucy's claim.

Answers

Answer:

x/2 = 1/2x

Step-by-step explanation:

# of paintbrushes/ 2 piles = 1/2 # of paintbrushes

Answer:

x/2

Step-by-step explanation:

Since Lucy is taking the paintbrushes, x, and splitting them into 2 equally sized groups we can assume that this IS 1/2 the size of the original group.

We can show this claim by simply doing this equation: x/2, since she is splitting them into 2 groups that are equally sized, we are just dividing x by two.

Jim and Joyce are saving for their annual vacation. They are going to Hawaii and their plane Tickets costs $2418 total. They have saved 1804 so far. If they are able to save $55 per week. how many weeks of saving will it take before they have saved at least S2418?

Answers

Answer:

12 Weeks.

Step-by-step explanation:

2418 minus 1804 is 614.

614 divided by 55 is 11.1, and you can't have 11.1, so you round to 12.

So 12 is therefore your answer.

2418 - 1804 = 614

614/ 55 = 11.163....

They will need to save for 12 more weeks because if they save for 11, they will only have 2408

h(x)=x2-5x+7 find when 1-3h(-8)

Answers

Answer:

The value of the expression is -332.

Step-by-step explanation:

We are given the following function:

[tex]h(x) = x^2 - 5x + 7[/tex]

We have to solve the following expression:

[tex]1 - 3h(-8)[/tex]

The numeric value at x = -8 is:

[tex]h(-8) = (-8)^2 - 5(-8) + 7 = 64 + 40 + 7 = 111[/tex]

The expression is:

[tex]1 - 3h(-8) = 1 - 3(111) = 1 - 333 = -332[/tex]

The value of the expression is -332.
