Answer:

7.8

Step-by-step explanation:

Given two points P(8,2) and Q(3,8). To find the distance between the two point can be gotten by using the formula for calculating the distance between two points on a line. The formula for calculating the distance between two points is given as;

d =√(x2-x1)²+(y2-y1)²

Where P(x1,y1) = (8,2)

Q(x2,y2) = (3,8)

From the points given, x1=8, y1=2, x2= 3, y2=8

substituting the values into the given formula, we will have;

Q-P = √(3-8)²+(8-2)²

Q-P = √(-5)²+6²

Q-P = √25+36

Q-P = √61

Q-P = 7.81

Q-P = 7.8(to the nearest tenth)

Distance between two points, d, is given by
d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }

where: (x1, y1) = (8, 2) and (x2, y2) = (3, 8)
d= \sqrt{ ( 3 - 8) ^{2} + (8 - 2) ^{2} } \\ d= \sqrt{ (-5)^{2} + 6^{2} }  \\ d= \sqrt{25+36}  \\ d= \sqrt{61}  \\ d=7.8 \ units

Under his cell phone plan, Elijah pays a flat cost of $64.50 per month and $5 per gigabyte. He wants to keep his bill at $87.50
timofeeve [1]

Step-by-step explanation:

Plan A: A = 20G

Plan B: B = 15G + 40

To see when they will be equal set the equations equal to each other

20G = 15G + 40

5G = 40

G = 8

At 8 GB they will cost the same amount.

20(8) = $160

15(8)+40 = $160

Hope it will be Helpfull

thank you

Felicia drove 245 miles and used 8.2 gallons of gas. At the same rate, if she drove 416 miles, how many gallons of gas will she
Anon25 [30]

245/8.2 = 416/x
245x = 3411.2
x = 13.9
So the answer is 13.9 gallons

Moretti's Ristorante & Pizzeria has two different soda sizes, Regular and Large. The Regular size soda is 22 ounces and the
Veseljchak [2.6K]

Answer:

280

Step-by-step explanation:

Given that:

The two different sizes of soda are:

Regular = 22 ounce

Large = 62 ounce.

The objective is to determine by what percent does the amount of the soda increase between the different soda size.

i.e. The ratio of the larger size in respect to the regular size:

So,

62/22 = 2.82

Thus in percent, the amount of the soda increase between the different soda size = 2.82 × 100%

= 282 percent

To the nearest percent, it is = 280
