Answer:

There are 2 equations together in each box, so what you need to do is graph them both. Then see where they intersect, that will be where the ufo they shot is. For example On the first two set of equations (y=x+6 & y=-x-4) when graphed together they intersect at (-5,1) which is where ufo 6 is. Meaning they shot Ufo 6

Given :

Rochelle is competing in a marathon.

She knows that once she runs 14.7 km she will have completed 35% of the marathon.

To Find :

Total length of the marathon.

Solution :

Let, total distance of the marathon is x km.

So, 35% of x is 14.7 .

In mathematics :

[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]

Therefore, total length of the marathon is 42 km.

Answer:

Do it yourself. You find the answer by using the midpoint formula (it is attached to this response). Just substitute the x and y values and do simple algebra.

Answer:

2.75 miles jogged on the fourth day

Step-by-step explanation:

Justin jogged 2 miles on the first day.

On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.

2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)

On the third day he jogged 1.5 miles more than the last day:

1.5 + 1.5 = 3 (6.5 miles jogged so far)

9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:

9.25 - 6.5 = 2.75 miles jogged on the fourth day

Answer:

Number of bagels = 10

Number of donuts = 25

Step-by-step explanation:

Let Number of bagels = b

Number of donuts = d

As given,

Each donut cost $0.55 and each bagel cost $1.20

⇒ Cost of d donuts = $0.55d

   Cost of b bagels = $1.20b

Also given,

Jamian bought a total of 35 bagels and donuts

⇒ b + d = 35     ........(1)

Also,

He paid a total of  $25.75.

⇒ 1.20b + 0.55d = 25.75          .........(2)

Now,

Multiply equation (1) by 1.20 , we get

1.20( b + d = 35 )

⇒1.20b + 1.20d = 42               ..........(3)

Now,

Subtract equation (2) from equation (3), we get

1.20b + 1.20d  - ( 1.20b + 0.55d ) = 42 - 25.75

⇒1.20b + 1.20d  - 1.20b - 0.55d  = 16.25

⇒0.65d = 16.25

⇒d = [tex]\frac{16.25}{0.65}[/tex] = 25

⇒d = 25

Put the value of d in equation (1) , we get

b + d = 35

⇒b + 25 = 35

⇒b = 35 - 25 = 10

⇒b = 10

∴ we get

Number of bagels = b = 10

Number of donuts = d = 25

Answer:

You would use the distributive property.

Step-by-step explanation:

2(x+4) = 2x+8

2x+8x = 2x+8

10x = 2x+8

10x - 2x = 2x-2x+8

8x = 8

8x/8 = 8/8

x = 1

Answer:

Step-by-step explanation:

These triangles are similar triangles, so there is a number that you can multiply the sides of TUV to find the side lengths of QRS. looking at the triangle, the similar sides are RS being similar to UV and RQ being similar to UT.

If RS~UV, then there is a ratio between them. 54/36=1.5. The ratio is 1.5.

RQ~UT, and by a factor of 1.5, so divide RQ by the scale factor. 24/1.5=16. UT=16=x+5.

x+5=16, subtract 5 from both sides.

x=11

Answer:

questions mistake look questions and apply the formula 1/2 B×H

if you have a triangle and don't know where are the base and the high use this formula

area = 0.5 × side  × side  × sin the angle between the 2 sides

area = o.5 (32.4) (49.2) (sin 18.5)

         = 797.04 × sin 18.5

          =252.9

Answer: b. C = 5 × ($0.75 × 4)

Step-by-step explanation:

Note that 4 quarts = 1 gallon

Therefore, if a cleaning product sells for $0.75 a quart, the equation can be used to solve for the total cost, C , of five gallons of the product will be:

= 5 × ($0.75 × 4)

= 5 × $3

= $15

Answer:

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

Step-by-step explanation:

We are given that

1/12,1/23,1/5,1/7,1/50,1/9,1/17

We have to arrange the numbers in ascending and descending order.

LCM of 12,23,5,7,50,9,17

[tex]23\times 5\times 12\times 7\times 50\times 17\times 9[/tex]

=73899000

[tex]\frac{1}{12}\times \frac{6158250}{6158250}=\frac{6158250}{73899000}[/tex]

[tex]\frac{1}{23}\times \frac{3213000}{3213000}=\frac{3213000}{73899000}[/tex]

[tex]\frac{1}{5}\times \frac{14779800}{14779800}=\frac{14779800}{73899000}[/tex]

[tex]\frac{1}{7}\times \frac{10557000}{10557000}=\frac{10557000}{73899000}[/tex]

[tex]\frac{1}{50}\times \frac{1477980}{1477980}=\frac{1477980}{73899000}[/tex]

[tex]\frac{1}{9}\times \frac{8211000}{8211000}=\frac{8211000}{73899000}[/tex]

[tex]\frac{1}{17}\times \frac{4347000}{4347000}=\frac{4347000}{73899000}[/tex]

14779800>10557000>8211000>6158250>4347000>3213000>1477980

Therefore,

Ascending order is given by

1/50<1/23<1/17<1/12<1/9<1/7<1/5

Descending order is given by

1/5>1/7>1/9>1/12>1/17>1/23>1/50

Answer:

40 respondents

Step-by-step explanation:

Percentage of respondents who watch TV for one hour each day = 75%

Number of respondents who watch TV for one hour each day = 30

Let [tex]x[/tex] denotes total of respondents who watch TV for one hour each day.

Therefore,

[tex]\frac{75}{100}x=30\\\\x=\frac{100}{75}(30)=40[/tex]

Answer:

Greater than 9 hours.

Step-by-step explanation:

Company A annual fees = $125

Company A share fee = $5 per hour

Let number of hour be x, then

Company A total fee = $125 + 5x

Similarly, Company B annual fees = $80

Company B share fee = $10 per hour

Let number of hour be x, then

Company B total fee = $80 + 10x

If company A is a better deal, then

125 + 5x < 80 + 10x

= 125 - 80 < 10x - 5x

= 45 < 5x

= x > 45÷ 5

= x > 9

So, number of hours must be greater than 9 hours.

A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
