Answer:

Rate of change/slope: 35

Miles at 10 hours: 350

Step-by-step explanation:

We can find the rate of change or the slope by using the slope formula below:

m = (y2-y1)/(x2-x1) where m is the slope

To find the slope, we can choose any two points from the table. I will choose (2,70) and (4,140)

m = (140-70)/(4-2)

m = 70/2

m = 35

The rate of change is 35 miles per hour

To find the miles at 10 hours, we can use the equation y = mx + b which is the equation of the line in slope intercept form. However, we will need to find the value of b. To do that, we can plug in any point from the table to find the value of b. I'll choose (2,70).

y = mx + b

70 = 35(2) + b

70 = 70 + b

b = 0

So the equation of the line would be y = 35x. Using this equation, we can find the number of miles at 10 hours:

y = 35(10)

y = 350

The number of miles at 10 hours is 350 miles

A grocer has 2 kinds of tea, one that sells for $8.00 per pound and the other that sells for $6.00 per pound. How many pounds of

Brilliant_brown [7]

Answer:

35 pounds of $8.00 tea and 15 pounds of $6.00 tea

Step-by-step explanation:

Let x represent the pounds of tea of the $8 kind. 8x would represent the total cost of that type of tea. We can also say 50 - x is the pounds of tea of the $6 kind, so 6(50 - x) is the total cost of that type of tea. 50 * 7.4 represents the total cost of all the tea, and the expression 8x + 6(50 -x) would also represent the same thing. We can write this as an equation,

8x + 6(50 -x) = 50 * 7.4

simplify,

8x + 300 - 6x = 370

2x + 300 = 370

and solve.

2x = 70

x = 35

This means there is 35 pounds of the $8 kind.

We can subtract that from 50 to find,

50 - 35 = 15,

15 pounds is the amount of the $6 kind.

Find the area of a circle with diameter 18 yd.

larisa [96]

Answer:

Area of the circle is 254.34 yd²

Step-by-step explanation:

Given:

Diameter of circle = 18 yd
π = 3.14

To Find:

Area of circle.

Solution:

Diameter = 18 yd
Radius = 18/2 = 9 yd

We know that,

$\: \: \: \: \dashrightarrow \: \: \: \: \: {\underline{\boxed{\sf{Area \: of \: circle = \pi r^2}}}} \\ \\$

Substituting the required values,

$\\$

$\: \: \: \: \dashrightarrow \: \: \: \: \: \sf Area_{(circle)} = 3.14 \times {(9)}^{2} \\ \\$

$\: \: \: \: \dashrightarrow \: \: \: \: \: \sf Area_{(circle)} = 3.14 \times 81 \\ \\$

$\: \: \: \: \dashrightarrow { \: \: \: \: \: \sf Area_{(circle)} = 254.34 \: {yd}^{2}} \\ \\$

Hence,

Area of the circle is 254.34 yd²

What is the equation of the time that passes through the poin3,2 ani has an undefined slope?

sesenic [268]

Answer:

$x=3$

Step-by-step explanation:

An undefined slope means it is a vertical line, and every possible point at that line is at x = 3. y does not depend on x, and x cannot be anything other than 3, so the equation is just $x=3$
