Answer:

  9, the sum of the numbers given in the ratio

Step-by-step explanation:

The reduced ratio 2 : 7 means that two parts correspond to one length and 7 parts correspond to the other length. That is, there are a total of 2+7 = 9 parts in the full length of the segment.

It is convenient to think of the line segment as being divided into 9 equal parts.

_____

Additional comments

It is often helpful to consider the total number of "ratio units" in a given ratio. For example, in this problem, the shorter segment is 2/9 of the whole, and the longer one is 7/9 of the whole.

It can also be useful to consider what a "ratio unit" represents. If the whole segment is 27 inches long, then each of the 9 ratio units will represent 3 inches, for example. This means the division 2:7 is 2(3 in):7(3 in) = 6 in : 21 in.

Answer:

Step-by-step explanation:

19)

6/x = x/12

x^2 = 72

x = √72

x = 6√2

y^2 = 12^2 + (√72)^2

y^2 = 144 + 72

y^2 = 216

y = 6√6

21)

14 - 8 = 6

y/8 = 6/y

y^2 = 48

y = √48

y = 4√3

x^2 = 6^2 +(√48)^2

x^2 = 36 + 48

x^2 = 84

x = √84

x = 2√21

Answer:

the 7th

0.007805 or  59 / 756

Step-by-step explanation:

To determine the Friday that he needed more pounds, determine the number of pounds he needed per dog for each Friday.

to do this, divide the total pounds by the number of dogs

on the 14th

3/8 ÷ 35 =

3/8 x 1/35 = 3/280

on the 7th

1/2 ÷ 27 =

1/2 x 1/27 = 1/54

to determine which fraction is larger multiply each by 100 to determine its percent

3/280 x 100 = 1.071

1/54 x 100 = 1.852

1/54 is larger. Thus, more pounds was needed on Friday the 7th

the difference between these fractions should be determined  

[tex]\frac{1}{54}[/tex] - [tex]\frac{3}{280}[/tex]

[tex]\frac{280 - 162}{1512}[/tex] = [tex]\frac{118}{1512}[/tex] = 59 / 756

Answer:

Part 1 : y = 0.75x

Part 2 : $750

Step-by-step explanation:

Part 1

Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.

Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have

sales price = regular price - discount

y = x - 0.25x

y = 0.75x

Part 2:  If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item

Since the sales price, y = 0.75x,and x = regular price = $1000,

substituting x into y, we have

y = 0.75x

y = 0.75($1000)

y = $750

Step-by-step explanation:

Since I haven't gotten a reply, I'll just do area and circumference.

Area = pi(r^2)

Circumference: 2(pi)r

7) r = 4/3 yd

pi = 22/7

Area = (22/7)(4/3)^2 = 5 37/63

Circumference = 2(22/7)(4/3)

8) d = 8.4, r (radius) is 1/2 of d, so r = 4.2

pi = 3.14

Area = (3.14)(4.2)^2 = 55.3896

Circumference = 2(3.14)(4.2) = 26.376

Answer:

8

Step-by-step explanation:

since there are 12 girls we have an x amount of girls who brought sleeping bags and 12-x for those who didn't. so

x/12=2/3

multiply both sides by 12

(x/12)12=(2/3)12

x=8

Answer: 2/3

Step-by-step explanation:

In the number cube, the possible numbers that can be gotten when it is rolled are 1, 2, 3, 4, 5 and 6.

We should note that when 2 or 4 is not rolled, there'll be 4 other numbers which can be rolled and they're 1, 3, 5 and 6.

Therefore, the probability of not rolling a 2 or 4 on a number cube having sides labeled with numbers 1-6 will be 4/6. This can be further reduced to 2/3

14.C

Step-by-step explanation:

Hello There!

For 13

The question is asking, which percentage would Darian most likely receive if he had studied for 9 hours.

The line of best fit would be used to determine the percentage he would most likely score based on the amount of hours he studied

Looking at the line of best fit we notice that at 9 hours Darian would most likely score a 78% on the test

Thus the answer is C

For 14

The question want you to find the graph that has a constant rate of change and has a y intercept of (0,0) so essentially

The question is asking "which graph best represents a proportional relationship."

If a relation is proportional it would have  a straight line and it would go through the origin (0,0)

Looking at C we notice that the line is straight ( meaning it has a constant rate of change) and it also goes through the origin therefore C is your answer

Answer:

4599

Step-by-step explanation:

Answer:

i dont think so

i dont know what the dot means so i will give you answers for everything

Step-by-step explanation:

63 plus 73 is 136

63 minus 73 is 10

63 times 73 is 4599

63 divided by 73 is 1.158730158730159

so if the dot meant plus minus times or divide that that is wrong

The course that a rescue ship must take from port in order to reach the disabled ship is 312.4 km at a direction of 50.2⁰.

The sketch of the journey of the ship can be used to determine the course that a rescue ship must take from port in order to reach the disabled ship.

                               | 240 km

                              ↓

The displacement of the ship from the initial position is calculated as follows;

d² = 200² + 240²

d² = 97,600

d = √97,600

d = 312.4 km

tanθ = 240/200

tanθ = 1.2

Answer:

to find the median you have to put the set in order and find the middle number (ex: 1,2,3,4,5,6,7,8,9 the median of this would be 5)

Step-by-step explanation:

City A: 2,2.5,2.5,3,4,4.5

The median has 2 number so you'd add them up and divide by 2.

2.5 + 3 = 5.5

5.5/2= 2.75

i dont know if you need it as a fraction

City B: 1.5,2,3.5,4,4,6

3.5+4 = 7.5

7.5/2 = 3.75

The dimensions of a rectangular plot are 50 yards by 41 yards.

To find:

The area of the plot.

Solution:

We know that, the area of a rectangle is

[tex]Area=Length\times width[/tex]

So, the area of the rectangular plot is:

[tex]Area=50\times 41[/tex]

[tex]Area=2050[/tex]

Therefore, the area of the rectangular plot is 2050 square yards.
