Answer:

2m + 3.10 = 21.10

m = 9

Step-by-step explanation:

First Step

2m + 3.10 =21.10

Subtract 3.10 from both sides

Second Step

2m = 18

Divide 2 from both sides

m = 9

The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Here,

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up fee $3.10 plus $2 per mile. The total fare was $21.10.

Now,

The equation is written as,

2m + 3.10 = 21.10

Subtract 3.10 from both sides

2m = 18

Divide 2 from both sides

m = 9

Hence, The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Answer:

The single discount that is the same as three successive discounts of 20% is 48.8%.

Step-by-step explanation:

In order to find the answer, you can calculate the three successive discounts of 20% from 100,which would be:

100*20%=20

100-20=80

80*20%=16

80-16=64

64*20%=12.8

64-12.8=51.2

According to this, the amount after successive discounts of 20% is 51.2 and you can subtract this from 100 and that amount would indicate the single discount that is the same as three successive discounts of 20%:

100-51.2=48.8%

Answer:

you can decide if you want this answer or not  :D

Step-by-step explanation:

1st  , notice that our problem is about an eight part whole.  I mean,  the questions are around an object of 8 parts.  so start thinking 1/8 ths

A) asks about P(7)  ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen  1/8 th of the time

as a fraction  it's  1/8  as a decimal it's 0.125 and as a percent it's 12.5 %

B) asks about  P(2 or 6 )   [ btw, p here stands for probability ]  

so it's  1/8 + 1/8 =  1/4  or one quarter of the time we would get a 2 or a 6

as a fraction it's  1/4  , as a decimal it's 0.25  and as a percent it's 25%

C)   asks  about P( greater than 4)  or  P( >4)   so that's the whole left side of the circle :0  

as a fraction it's 1/2  as a decimal it's 0.5  and as a percent   it's 50%

D) P( not a 5) or P( ~=5)  so every thing but a 5

as a fraction that's 7/8  as a decimal it's 0.875 and as a percent that 87.5 %

I'll take the odds on that last one to win the lottery plz  :)

Answer:

x = 9

Step-by-step explanation:

-5(1 + 1x) = -50

-5 + -5x = -50

-5 + -5x + 5 = -5x

-50 + 5 = -45

-5x = -45

-5x / -5 = x

-45 / -5 = 9

x = 9

Answer:

140 students are probably 10th graders

Step-by-step explanation:

This survey is supposed to represent the whole of the group, and so it is reasonable to assume that the ratios and percentages of people in each grade would be equal in the same as it is in the whole. For this sample, we have a total of 30 people surveyed (14+8+5+3), and 14 of them are 10th graders. Then, you would set up a proportion to find the number of 10th graders in 300. The equation would be 14/30=x/300. This isnt very hard to figure out because you just cross multiply to get 30x=4200, and you then divide each side by 30 to isolate x, which leaves you with x=140. This leaves you with the answer that 140 students are 10th graders.

Lokking at the bar graph as shown, the number of tenth graders is 140.

A bar graph is means of data presentation in which the quantity of data is shown using the height of bars rather than the use of points a in a scatter plot.

In this case, we can see from the bar graph that the number of tenth graders is 140 since the bar graph is reported to the power of 10^1.

Answer:

The length of GH is 2 inches

Step-by-step explanation:

The given parameters are;

Parallelogram ABCD ~ Parallelogram EFGH

Segment BC of parallelogram ABCD corresponds to segment FG of parallelogram EFGH

Similarly

Segment CD of parallelogram ABCD corresponds to segment GH of parallelogram EFGH

In parallelogram ABCD, we have;

Segment BC = 21 in.

Segment CD = 6 in.

In parallelogram ABCD, we have;

Segment FG = 7 in.

Given that parallelogram ABCD is similar to parallelogram EFGH, we have;

[tex]\dfrac{\overline{BC}}{\overline{FG}} = \dfrac{\overline{CD}}{\overline{GH}}[/tex]

Which by substitution, gives;

[tex]\dfrac{21}{7} = 3 = \dfrac{6}{\overline{GH}}[/tex]

[tex]\therefore \overline{GH} = \dfrac{6}{3} = 2[/tex]

[tex]\overline{GH}[/tex]= 2 inches
