Joshua does not want to spend more than $22 on a long-sleeve shirt. Which description of shirt prices would keep joshua within his spending limit, not including tax? Select all that apply a- 15% off %25 b- 30% off 32% c-19.65 plus 2.35 shipping fee d- 20.45 plus a $1.60 shipping fee

Answers

Answer 1
Answer:

Answer:

the answer is C

Step-by-step explanation:

19.65 + 2.35 is exactly 22, not including tax
Answer 2
Answer:

Answer:

A and C

Step-by-step explanation:

A. 15% off $25

15% = 0.15

0.15 x 25 = 3.75

25 - 3.75 = 21.25

22 or under? Yes

B. 30% off $32

30% = 0.30

0.30 x 32 = 9.60

32 - 9.60 = 22.40

22 or under? No

C. $19.65 plus a 2.35 shipping fee

19.65 + 2.35 = 22

22 or under? Yes

D. $20.45 plus a $1.60 shipping fee

20.45 + 1.60 = 22.05

22 or under? No

Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!

What is the y-intercept of this graphed line?
PLEASE HELP!!!!!!

Answers

I believe the answer is b)-3.
The y-intercept is when a point passes through the y-axis. Hope this helps:)

Final answer:

To find the y-intercept of the given linear function, first, the slope of the function is calculated using the provided points. Then, the slope and one pair of coordinates are substituted into the y = mx + b equation to solve for 'b', which is the y-intercept.

Explanation:

In mathematics, specifically in the context of linear functions, the y-intercept is the point at which the line crosses the y-axis. From the provided points, however, it's not immediately clear what the y-intercept is.

To find the y-intercept, we need to determine the line's equation first. The equation of a line can be represented in the form y = mx + b, where 'm' is the slope of the line and 'b' is the y-intercept. To find the slope, we use the formula (y2 - y1) / (x2 - x1), substituting the given points. After calculating the slope, we can plug one pair of the given coordinates into the equation y = mx + b, and solve for 'b', which gives us the y-intercept.

What is the equation in point−slope form of the line passing through (−2, −5) and (2, 3)?(A. y+2 = -2(x+5); B. y-2 = 2(x-3); C. y-3 = 2(x-2); D. y+3 = -2(x+2))

Answers

Hi,

m = (y-y₀)/(x-x₀)
m = (-5-3)/(-2-2)
m = -8/-4
m = 2

For point (2,3) ⇒ x₀ = 2 and y₀ = 3

y-y₀ = m(x-x₀)
y-3 = 2(x-2)

For point (-2,-5) ⇒ x = -2 and y = -5

-5-3 = 2(-2-2)
-8 = 2(-4)
-8 = -8 ⇒ True

Answer: 

C. The equation is y-3 = 2(x-2)

A manufacturer makes ball bearings out of molten steel. It takes 5.24 cubic centimeters of molten steel to make ? ball bearings that each have a diameter of 1 centimeter.

Answers

So we want to know how much ball bearings can be made with 5.24 cm^3 if one ball bearing has a diameter of 1 cm. We know that radius r=d/2=0.5cm So the volume V of one ball bearing is: V=(4/3)*pi*r^3 so V=(4/3)*3.14*(0.5)^3cm^3=0.524cm^3. Now we simply divide the volume of steel by the volume of the ball bearing: 5.24/0.524=10. So we can make 10 ball bearings from 5.24 cm^3 of steel

Answer: 10 ball bearings

The cost of parts on your automobile repair bill was $149. The cost for labor was $25Per hour. Write a linear equation giving the total cost C, in terms of t, the number of
Hours. C(t)

Answers

Answer:

C=149+25t

Step-by-step explanation:

Since the total cost is C you would set it all equal to C.

Then the one time cost for parts was 149 so you have to add that in.

And $25 per hour would be multiplied by t because t is the number of hours.
