Answer:

Gemma made $34 more than Leah.

Step-by-step explanation:

Gemma made number of beaded necklaces = 106

Leah made 39 more necklaces than Gemma.

Leah made number of beaded necklaces = 106 + 39 = 145

a. There are 104 beads on each necklace.

The total number of beads used altogether

= (106 × 104) + (145 × 104)

= 11,024 + 15,080

= 26,104

b. Gemma sold her 106 necklaces for = $14

Total price of her necklaces = 106 × 14

= $1,484

Leah sold her 145 necklaces for = $10

Total price of her necklaces = 145 × 10

= $1,450

Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00

Therefore, Gemma made $34.00 more money than Leah.

Suppose you are covering your desk (shape below) with paper and want to know how many square inches of paper you need.

zavuch27 [327]

Answer:

a. Divide the figure into two rectangles, find the area of each rectangle and add them (See the picture attached).

b. $279\ in^2$

c. The total area of the figure is 279 square inches.

Step-by-step explanation:

a. Divide the figure into two rectangles (See the picture attached), then find the area of each rectangle and finally, add the areas calculated in order to get the total area of the given figure,

b. The area of a rectangle can be found using this formula:

$A=lw$

Where "l" is lenght and "w" is the width.

Area of Rectangle A

You can identify that:

$l_A=19\ in\\\\w_A=11\ in$

Then, its area is:

$A_A=(19\ in)(11\ in)=209\ in^2$

Area of Rectangle B

You can identify that:

$l_B=10\ in\\\\w_B=18\ in-11\ in=7\ in$

Then, its area is:

$A_B=(10\ in)(7\ in)=70\ in^2$

Total area

$A_T=209\ in^2+70\ in^2=279\ in^2$

c. The total area of the figure is 279 square inches.

Hi! this question applies to #43

Anika [276]

When an absolute value is changed in the horizontal, the units in change are inside the "bars", and are as follows: left = positive, right = negative.

Therefore, the equation is y = | x - 6.5 |.
