What is the slope of the line?

Answers

Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Step-by-step explanation:

Answer:

slope = [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]

1. What is 7/50 as a Percentage?

2. What is 3/25 as a Percentage?

3. What is 3/16 as a Percentage?

Please help!

Answers

1. What I do is get the 7/50 to have the denominator as 100 so I just double the 50 and the seven and get 14/100 so it’s 14%.

2. Same thing except 25 goes into 100 four times so I multiple the 3 and 25 by four and get 12/100 so it’s 12%.

3. Do 3 divided by 16, and you get .1875. So that’s 18.75% or you can do 100 divided by 16 and get 6.25. Then you multiply the 6.25 times the 3 and get 18.75%

Nick is buying one DVD player and some DVDs. At Electronics-R-Us, the DVD player is $60 and the DVDs are $12 each. At Movies-n-More, the DVD player is $80 and movies are $10 each. If the cost at the two stores is equal, how many DVDs did Nick purchase?​

Answers

if he buys 5 DVDs at electronic-r-us plus the player it would be a total of $120
60+12(5)=60
if he buys the player plus 4 movies at movies-n-more the total would also be $120
80+12(4)=60
so in total he purchased 9 DVDs

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?

Answers

Answer: 128.7 inches

Step-by-step explanation:

Josh's height is 66 inches.

When he jumps with a running start, he can jump as far as 195% of his height.

The length he can jump is therefore 195% multiplied by his height:

= Josh height * 195%

= 66 * 195/100

= 128.7 inches

Answer: 128.7

It’s D! Have a great day

The measurement of the circumference of a circle is 21.3 ft.

What is Circumference of Circle?

The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

Here, given area of circle = 36 ft²

Area of Circle = πr²

           36 = 3.14 X r²

           r² = 11.46

          r = 3.38 ft.

Circumference of Circle = 2πr

                                       = 2 X 3.14 X 3.38

                                      = 21.25 ft. ≈ 21.3 feet

Thus, the measurement of the circumference of a circle is 21.3 ft.
