HURRY!!! THIS ASSIGNMENT IS ALREADY LATE! THANK YOU!

11. During an evening out, Dean paid a cab driver $20. He
then spent $25 on dinner and half of his remaining money on a painting. He bought an umbrella for $23.75 and had $42.15 left. How much money did Dean have at the beginning of the weekend?

Answers

Answer 1
Let total amount be x.
Cab - $20
Dinner - $25
Remaining Amount- (x-45)
Hlf of this amount was spent on painitng. So, net cash in hand is (x-45)/2.

out of this cash in hand, he has gt umbrella for 23.75, and balance cash is 42.15.

so, (x-45)/2=23.75+42.15

(x-45)/2=65.9
x-45=131.8
x=176.8

Amount Dean had at the beginning of the weekend = $176.8
Answer 2

Answer:

$176.80

Step-by-step explanation:

$42.12 (what he had left) + 23.75 = 65.90

65.90 (Amount he had after he bought the painting) + 65.90 (The other half of his remaining money he spent on the painting) = 131.80

131.80 + 25 + 20 = 176.80

= $176.80

12r-5 Lets multiply everything by 2 since we are given nothing to simplify
24r-10 now we have to make it equivalent to 12r-5

Step-by-step explanation:

According to PEMDAS, the first step would be to take care of the exponents. -7 times -7 is positive 49, so the equation would look like this:

A 12 m object is represented in a picture as being 2 cm. What is the scale?

Answers

Answer: 1:600

Step-by-step explanation:

From the question, we are informed that 12 m object is represented in a picture as being 2 cm.

To find the scale used, we needed to convert 12m to cm. Since 100cm = 1m, then 12m = 12 × 100 = 1200cm.

Therefore, a 1200cm object is represented in a picture as being 2 cm. The scale will be:

= 2/1200

= 1/600

= 1:600

This means that 1 centimeter in the picture represent 600 centimeter or 6 meters.

Answers

The equation would be:

y = 3x + 15

1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y

2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15

3) you already defined the variables

4) 3(5)+15 = 15+15 = 30 seashells

Stock Market At the beginning of the day the stock market goes down 50 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 120 1/2 points from the at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the​ day?

Answers

Answer:

69 3/4

Step-by-step explanation:

The stock market goes down to 50 3/4 at the beginning of the day

At the end of the day it goes up to 120 1/2

Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows

= 120 1/2 - 50 3/4

= 241/2 - 203/4

= 279/4

= 69 3/4

Hence the total change in the stock market from the beginning to the end of the day is

69 3/4

One yardstick for measuring how steadily—if slowly—athletic performance has improved is the mile run. In 1958​, the local record for the running of a certain distance was 3​ minutes, 59.3 ​seconds, or 239.3 seconds. In the​ half-century since​ then, the record has decreased by 0.5 seconds per year.

Answers

Answer:

They will hit 180 seconds in 118.6 year

Step-by-step explanation:

Let M be the record for the mile (in seconds)

Let x be the year after 1958

So, x=(year)-19548

We are given that In the​ half-century since​ then, the record has decreased by 0.5 seconds per year

So, slope = m = 0.5

Now we will use point slope form

y = mx+c

So, we can express M as,

[tex]M=239.3-0.5 \times x[/tex]

Now we are supposed to find when they will hit 180 seconds

Substitute M = 180 in equation

180=239.3-0.5x

x=118.6

So, they will hit 180 seconds in 118.6 year
