Ethan ran 11 miles in 2 hours. What is the unit rate of miles to hour?

Answers

Answer:

5.5 mph

Step-by-step explanation:

Answer:

5.5 miles per hour

Step-by-step explanation:

This is a fraction equal to

11 miles ÷ 2 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2

11 miles ÷ 2

2 hours ÷ 2

=  

5.5 miles

1 hour

=  

5.5 miles

hour

= 5.5 miles per hour

Due to a bad crop year, the cost of cherries is projected to increase 133% this year. A pound of cherries currently costs $2.16. What can you expect the new price per pound to be?

Answers

To solve this problem, or one of sorts, you can multiply the current price (2.16) by 1.33 (the percentage as a decimal).

2.16*1.33 = 2.8728

Round to two decimal places (and that’s the number of decimal places for money), and you can expect the new price per pound of cherries to be about $2.87.

what is the equation of the line in slope intercept form

Answers

Answer:

y=x-70

Step-by-step explanation:

Y= x-70 is correct.
To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

Please help me I beg you I will give you credit plz

Answers

Find slope (y2-y1)/(x2-x1)
Pick any two points on line
(1,15) and (2,25)
(25-15)/(2-1) = 10/1, slope is 10 (rate of change)
Y = 10x + b
15 = 10 + b
The y intercept would be 5

Anna makes unique jewelry. The owner of the "Unique" store agreed with Anna to deliver 20 bracelets a week. At the moment, Anna has 80 bracelets made, and can make 17 bracelets a week. For how many consecutive weeks will Anna be able to supply her bracelets to the "Unique" store?

Answers

Answer:

7 weeks

Step-by-step explanation:

80 ÷ 20 = 4

She over those four week she makes 17 per week. So,

17 × 4 = 68

Next, divide the product by 20:

68 ÷ 20 = 3.4

But 3.4 is only 3 full weeks so then its 3.

Lastly, add the 3 weeks we just solved for the the 4 weeks from before and you get 7 weeks.

So, Anna will be able to supply the "Unique" store for 7 weeks.

What are the coordinates of the vertex of the graph of the absolute value function h(x) = 3|x + 5| + 2?

Answers

Answer:

(-5,2)

Step-by-step explanation:

h(x) = 3|x + 5| + 2 is an absolute value function in vertex form. Vertex form is f(x) = a | x - h | + k with a vertex at (h,k). So find h and k in the function, 3|x + 5| + 2, but remember in the formula h is negative so flip the sign of what ever is in your function. So if h=-5 and k=2, then the vertex is (-5,2).
