Answer:

Each person will pay $9.78

Step-by-step explanation:

Given that:

Amount of bill = $34

Tip = 15%

Amount of tip = [tex]\frac{15}{100}*34[/tex]

Amount of tip = 0.15 * 34

Amount of tip = $5.10

Amount after bill = 34 + 5.10 = $39.10

Number of people = William + three friends = 4

Per person share = [tex]\frac{39.10}{4}[/tex]

Per person share = $9.775

Rounded to two decimal places

Per person share = $9.78

Hence,

Each person will pay $9.78

Answer:

Plane A:

The rate of change or slope of function A is: m = 470

It means plane A is flying 470 miles per hour.

Thus, the rate of speed of plane A is 470 miles per hour.

Plane B:

The rate of change or slope of Plane B is: m = 480

It means Plane B is flying 480 miles per hour.

Thus, the rate of speed of plane A is 480 miles per hour.

Therefore, we conclude:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Plane A

From the given equation

y = 470x

where

x is the time that plane flies in hours

y is the distance the plane flies in miles

Thus, comparing with the slope-intercept form y = mx+b

The rate of change or slope = 470

It means plane A is flying 470 miles per hour.

Plane B

Given the table

Time (h)                 1            2             3            4

Distance (mi)        480       960         1440     1920

Finding the slope by taking any two points, let say, (1, 480) and (2, 960)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:480\right),\:\left(x_2,\:y_2\right)=\left(2,\:960\right)[/tex]

[tex]m=\frac{960-480}{2-1}[/tex]

Refine

[tex]m=480[/tex]

Therefore, the rate of change or slope of Plane B is: m = 480

It means Plane B is flying 480 miles per hour.

Conclusion:

Plane A:

The rate of change or slope of function A is: m = 470

It means plane A is flying 470 miles per hour.

Thus, the rate of speed of plane A is 470 miles per hour.

Plane B:

The rate of change or slope of Plane B is: m = 480

It means Plane B is flying 480 miles per hour.

Thus, the rate of speed of plane A is 480 miles per hour.

Therefore, we conclude:

Answer:

8 but you would have a remainder of 1

Step-by-step explanation:

4x8 is 32 so 8 r1

Step-by-step explanation:

at 3=3

at 0=9

at 4=1

[tex]y = ax + b[/tex]

[tex]1 = 4a + b \\ 3 = 3a + b \\ 2 = - a \\ a = - 2 \\ 1 = - 4 \times 2 + b \\ b = 1 + 8 = 9 \\ y = - 2x + 9[/tex]

Answer:

y=-2x+9

Step-by-step explanation:

From looking at the line you can already tell that the slope is going to be negative, and the y-intercept is going to be 9, since that's where y is when x is 0. You can see that when x is one, y is 7. When x is 2, y is 5. And when x is 3, y is 3.

So:

0: 9

1:7

2:5

3:3

And the difference of y over the difference of x is the slope

-2/1=-2

So the slope is -2

Therefore, putting the equation together makes:

y=-2x+9

Hope this helps!

Answer:x=4 y=-2

Step-by-step explanation:

3x-5y=22

3x+1.5y=9

-6.5y=13

6.5y=-13

0.5y=-1

Y=-2

Replace/substitute

2x-2=6

2x=8

X=4

2x+y=6---------(2)

y=6-2x---------(3)

putting value of y on equation

3x-5y=22

3x-5(6-2x)=22

3x-30+10x=22

13x=22+30

13x=52

x=52/13

x=4

putting value of x on equation (3)

y=6-2x

y=6-2.4

y=6-8

y=-2

Answer:

Rhian did better in the Math test.  

Step-by-step explanation:

Given: Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test. In the English test she scored [tex]31[/tex] out of [tex]39[/tex].

To find: In which test did she do better?

Solution:

We have,

Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test.

Rhian scored [tex]31[/tex] out of [tex]39[/tex] in an English test.

So, first we need to find the percentage of the marks scored.

Percentage in the Math test [tex]=\frac{14}{17}\times100=82.35 \%[/tex].

Percentage in the English test [tex]=\frac{31}{39}\times100= 79.49\%[/tex].    

Clearly, the percentage in the Math test is greater than the percentage in the English test.

So, Rhian did better in the Math test.    

Answer:

Answer:

[tex]\frac{3}{5} = \frac{18}{30}[/tex]

Step-by-step explanation:

To solve this proportion, we will divide the two given denominators.

Now, we have: 30 ÷ 5 = 6

Next, we will multiply the given numerator by the quotient: 3 × 6 = 18

So, our final proportion will have to be:

[tex]\frac{3}{5} = \frac{18}{30}[/tex]

Answer:

X = 18

Answer:

Approximately [tex]3410[/tex] steps each hour.

Step-by-step explanation:

Given: On Tuesday, Julissa worked from 9:00 A.M. to 3:00 P.M.

Julissa had walked [tex]20,458[/tex] steps preparing orders to be shipped.

To find: Number of steps, approximately, she walked each hour.

Solution: We have,

Total number of steps [tex]=20,458[/tex] steps.

Number of hours, from 9:00 A.M. to 3:00 P.M. [tex]=6[/tex] hours.

So, number of steps she walked each hour [tex]=\frac{20,458}{6} =3409.67[/tex] steps.

Hence, Julissa walked approximately [tex]3410[/tex] steps each hour.
