Natalie needs to save $479.58 for a vacation. She saved $149.88, and earns $7.85 an hour working at the grocery store. How many hours must she work to meet her goals?

Answers

Answer:

42 hours

Step-by-step explanation:

Natalie needs to save a total of $479.58

She already saved $149.98

The amount left to save is

= 479.58-149.98

= 329.7

If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows

= 329.7 / 7.85

= 42

Hence Natalie will work for 42 hours to meet her goals

Angle a​ and​ ​angle b​ ​are complementary angles. The measure of ∠a is 42°.

Which equation represents this situation with x representing the measure of ∠b?




42−x=90

90+x=42

42+x=90

90+42=x

Answers

Answer:

42+x=90

Step-by-step explanation:

Complementary angles are when their measures add up to 90°

Therefore, if angle a is 42° you would find angle b by subtracting 42° from 90° which is shown in equation number three.

Victor and his cousin are playing a game where they pick up colored sticks. Victor currently has 26 points and likes to pick up the purple sticks, earning 7 points every turn. His cousin just lost all his points on the previous turn, and has a strategy to catch up by getting all the red ones, earning 20 points per turn. In a certain number of turns, the score will be tied. How many points will they each have? How long will that take?


Victor and his cousin will each have__ points in __turns.

Answers

Answer:

They each will have 20 points

it will take 2 turns

Victor and his cousin will each have 20 points in 2 turns

Step-by-step explanation:

let the number of turns it will take be x

In x turns, the number of points Victor will have is;

26 + 7(x) = 26 + 7x

In x turns, the number of points the cousin will have is:

20 * x = 20x

so we can get x from here;

20x = 26 + 7x

20x-7x = 26

13x = 26

x = 26/13

x = 2

In two turns, the number of points will be 20(2) = 40 points

It will take 2 turns

Victor and his cousin will each have 40 points in 2 turns
