# Karina needs a total score of at least 627 on three games of bowling to break the league record. Suppose she bowls 222 on her first game and 194 on her second game. What score does she need on her third game to break the record?

QUESTION POSTED AT 06/12/2019 - 01:56 PM

Add 222 and 194 together; 416. Then subtract; 627 - 416 = 211. Add one because that means she got over 627. She needs to get a score of 212 to beat the record. I hope that helps!

### Bill makes leather shoes. He charges $45 for a pair of women's shoes and$50 for a pair of men's shoes. He sells x pairs of women’s shoes and y pairs of men’s shoes each week and earns a total income of $2,500. This situation can be represented by the equation 45x + 50y = 2,500 (45 + 50)xy = 2,500 . If Bill has no female customers during a particular week, he needs to sell 45 50 pairs of men’s shoes to earn his weekly income of$2,500. NextReset

Essentially, the question can be rephrased as "if Bill wants to make 2500 dollars, how many male shoes does he have to sell"?

we divide 2500 by the prize of a male pare of shoes, 50 dollars:

2500/50=50

so he has to sell 50 pairs of male shoes!

Let x represent the number of days and y represent the total number of minutes walked during the challenge. Which system of equations can be used to find the number of days it will take for Owen and Jamie to have walked the same number of minutes? A) y= 20x + 120 y=30 B) y=20x y=30x + 120 C) 120x + 20 y=30 D) y=120x y=30x +20

I think the best answer would be letter B. Y= 20x and Y= 30x+120. So by calculating it through substitution you will come up to 20x = 30x+120. By simplifying the equation it will give you an answer of 12 days.

Step-by-step explanation:

As given

McNeary brought home a weekly pay check with these deductions:

Federal - $45.67, FICA -$ 24.63, state - $19.04. As there are 52 weeks in a year . Thus Federal deduction in one year = Federal deduction per week × Number of weeks in a year . Put all the values in the above Federal deduction in one year =$ 45.67 × 52

= $2374.84 FICA deduction in one year = FICA deduction per week × Number of weeks in a year . Put all the values in the above FICA deduction in one year =$ 24.63 × 52

= $1280.76 State deduction in one year = State deduction per week × Number of weeks in a year . Put all the values in the above State deduction in one year =$ 19.04 × 52

= $990.08 Thus Total deduction in a year = Federal deduction in one year + FICA deduction in one year + State deduction in one year . Put all the values in the above Total deduction in a year =$ 2374.84  + $1280.76 +$ 990.08

= $4645.68 Therefore McNeary pays annually in total deductions is$ 4645.68 .

### A cashier has a total of 26 bills made up of tens and hundreds the total value is 1610 how many hundreds and tens does she have?

Let the tens be x.

Therefore the hundreds will be (26 - x).

Since they both total to 26. x  + (26 - x) = 26

10*x + 100*(26 - x) = 1610

10x  + 2600 - 100x = 1610

10x - 100x = 1610 - 2600

-90x = -990

x = -990/-90

x = 11.

So the 10s are x =11,   the 100s  are (26 -11) = 15

11 tens bills and 15 hundred bills.

15

1st bounce = 0.70*15 = 10.5

2nd bounce = (0.7)*(0.7)*15 = 7.35

3rd bounce = (0.7)*(0.7)*(0.7)*15 = 5.145

4th bounce = (0.7⁴)*15 = 3.6015

5th bounce = (0.7⁵)*15 = 2.52105

6th bounce  = (0.7⁶)* 15 = 1.764735

7th bounce = (0.7⁷)*15 = 1.2353145

8th bounce = (0.7⁸)*15 = 0.86472015

10.5 + 7.35 + 5.145 + 3.6015 + 2.52105 + 1.764735 + 1.2353145 + 0.86472015 = 32.98231965

Between the time it was dropped and the eight bounce.

That means we need to add the first 15 m it traveled when initially dropped.

15 +  32.98231965 = 47.98231965 m.

None of the options has a value around 47.98 m.
