How do the mathematical domain and reasonable domain compare?

Answers

Answer 1

Answer:

Mathematical domain is all numbers, as all numbers can be multiplied by 4. However, this is not reasonable as negative lengths don't exist, so the reasonable domain would be all positive numbers.

Pierre had $42 before he paid his club dues. Evaluate the expression 42 − d for d = 25 to find how much money Pierre had left after he spent $25 on dues

Answers

Answer:Pierre has $17 left

Ja'kniya and Alayjah are shopping at the Apple Store. Ja'kniya bought 4 screensavers and 3 Otterboxes for $29. Alayjah bought 6 screensavers and 2 Otterboxes for $26. How much did each screensaver and each Otterbox cost?

Answers

Answer:  Each screensaver costs $2 and each Otterbox costs $7.

Step-by-step explanation:

Let x = Cost of each screensaver and y = cost of each Otterbox.

As per given, 4x+3y=29       (i)

6x +2y = 26  (ii)

Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get

9x+3y=39    (iii)

Eliminate (i) from (iii) , we get

5x = 10

⇒ x = 2  [Divide both sides by 5]

Put value of x in (i), we get

4(2)+3y=29

⇒ 8+3y= 29

⇒ 3y= 21

⇒ y =7 [Divide both sides by 7]

Hence, Each screensaver costs $2 and each Otterbox costs $7.

Step-by-step explanation:

First distribute the -4 with the (-5x+12) which should be 20x-48 and then simplify and it should be 43=13x-48. Then add 48 to both sides which should be 91=13x. Lastly divide 13 on both sides and that should be 7x.

Rachel has ridden 68 miles of a bike course. The course is 80 miles long. What percentage of the course has Rachel ridden so far?

Answers

Answer:

92%

Step-by-step explanation:

since i helped can i have brainlst please that would be greatly apericated

Answer:

85%

Percentage solution with steps:

Step 1: We make the assumption that 80 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 80.

Step 4: In the same vein, x% = 68.

Step 5: This gives us a pair of simple equations:

100% = 80(1)

x% = 68(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left-hand side) of both equations have the same unit (%); we have

100%/x% = 80/68

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100% = 68/80

__>x = 85%

Therefore, 68 is 85% of 80.

A grocery store offers 10 gas points of gas for every $50 you spend on groceries. For every 10 gas points you earn, you get to take $0.10 off every gallon of gas you buy. Currently, gas is $3.25 per gallon. When Monica fills up her car, she usually puts around 12 gallons of gas in it. How much money must Monica spend at the grocery store to fill up her car for less than $35.00?

Answers

Answer: $2,000

Step-by-step explanation:

Gas is $3.25 per gallon. If Monica needs 12 gallons, cost would be:

= 12 * 3.25

= $39

If she wants to fill up for less than $35, she will have to earn the difference in points:

= 39 - 35

= $4

One can get $0.10 off for every $50 spent. The number of 10 cents in $4 is:

= 4 / 0.1

= 40

Monica would therefore have to spend:

= 50 * 40

= $2,000

by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?

Answers

Answer:

The answer is C

Number of days= 21/8

Step-by-step explanation:

The inequality to represent the given situation is [tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]. Therefore, option B is the correct answer.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Joseph runs [tex]2\frac{1}{2}[/tex] miles on Monday. Each day after that, he runs the same [tex]1\frac{1}{3}[/tex] mile route every morning.

Let the number of days be x.

Here, the inequality is

[tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]

Therefore, option B is the correct answer.
