Magic LinesCan You Put The Numbers 2 To 8 In The Circles So That Every Lineadds Up To 15? You Can Use

Answers

Answer 1

Answer:

Please see attached image

Step-by-step explanation:

The numbers on the upper row should be:  7   6   2

the number in the central disk should be    5

the bottom row should read  : 8   4   3

The addition on top row: 7 + 6 + 2 = 15

the addition on bottom row:  8 + 4 + 3 = 15

the addition on the central vertical column: 6 + 5 + 4 = 15

diagonal going down:    7 + 5 + 3 = 15

diagonal going up:   8 + 5 + 2 = 15

What is an equation of the line that passes through the points (-7,-7) and (-7,4) ?​

Answers

(-7,-7) and (-7,4)

First we need to find the slope between these two points

(y2-y1) / (x2-x1) = -11 / 0 =

Therefore there is no slope.

The most a baker can spend on strawberries is $95.00. Strawberries cost $3.99 per pound, and the produce supplier charges a $15.20 delivery fee. The following inequality, where s stands for the number of pounds of strawberries, represents this situation:

Answers

Answer:

3.99s + 15.20 = 95.00

Step-by-step explanation:

you would put 's' next to the 3.99 because that's what your multiplying or having more than 1 of, then you would add the 15.20 because it's just a one time delivery fee.

Answer:

The answer is 20

Isolate the variable by dividing each side by factors that don't contain the variable.

Answers

Answer:

a. When you have two parallel lines cut by a transversal, angles 4 and 6 become same side interior angles, meaning they add to 180 degrees. Alex's mistake is that he thought angles 4 and 6 were corresponding angles, which are equal to each other (corresponding angles would be like angles 2 and 6. they are in the same place in relation to the transversal and the parallel lines. if you moved line l down, angle 2 would be on the same spot as angle 6, so they are corresponding angles).

b. angles 4 = 140 degrees

Step-by-step explanation:

a. Alex thought that angles 6 and 4 were corresponding angles, however, they are same side interior angles. Because two parallel lines are cut by a transversal, we can conclude that angles 4 and 6 are same side interior angles.

Same side interior angles are angles that add to 180, so you would do 180-40 to get angle 4. the measure of angle 4 would be 140 degrees (the answer to b).

1. If a 10% increase in price leads to a 40% decrease in quantity demanded, what is the value of price
elasticity of demand? show your work

Answers

Answer:

-30

Step-by-step explanation:

10 - 30 is not possible they owe

The value of price elasticity of demand is -4.

The price elasticity of demand refers to how a particular good responds as a result of a change in the price. In this case, the price elasticity of demand is calculated as:

= Percentage change in quantity/ Percentage change in price.

Since a 10% increase in price leads to a 40% decrease in quantity demanded, the price elasticity will be:

= - 40% / 10%

= -4.

If an individual is selected at random, what is the probability that he or she has a birthday in July? Ignore leap years.

Answers

1/12 because there are 12 months

The probability is  [tex]\frac{31}{365}[/tex]  , If an individual is selected at random have birthday in July  .

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]

According to the question

Total number  of days in year = 365

Total number of days in a leap year = 366

As, given  Ignore leap years

So, we will take days of years as 365 .

Now,

he or she has a birthday in July

i.e ,

It can be be happen any day of July

Total days in July = 31

Now,

Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex] = [tex]\frac{x}{n}[/tex]

substituting the value

Probability(Event) = [tex]\frac{Total\\\ day\\\ in\\\ July }{Total\\\ days\\\ in\\\ year}[/tex]

Probability(Event) = [tex]\frac{31}{365}[/tex]

Hence, If an individual is selected at random the probability have birthday in July  is  [tex]\frac{31}{365}[/tex]  .

Pat started reading at 1pm . He reads five pages in 15 minutes. If Pat reads until 2:45 pm, how many pages has he read?

Answers

Answer:

35 pages

Step-by-step explanation:

First count how many minutes have passed. Divide by 15, then multiply by 5 since 5 pages are read every 15 minutes.

Answer:

35 pages

Step-by-step explanation:

If Pat reads 5 pages in 15 minutes, then it means that for every 5 pages he reads, it will take him 15 minutes. So, his rate is 5/15, simplified to 1/3. For every 1 page he reads, it will take him 3 minutes. 1pm-2:45pm is 1 hour and 45 minutes, which is 105 minutes. Now we just have to divide it by 3, since he reads 1 page every 3 minutes. 105/3=35. He will read 35 pages.
