What is the slope for this question?

Answers

Answer:

[tex]-1[/tex]

Step-by-step explanation:

This is a really nice line that goes through a lot of grid points (where the lines intersect).

One easy way to find the slope is the phrase "rise over run."  "Rise" is the name for vertical motion from point-to-point.  "Run" is the name for horizontal motion from point-to-point.

Pick two easy points on the line, say (0, 0) and (1, -1).

If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.

The run is 1 -- because you went RIGHT 1 unit.

[tex]\frac{\text{rise}}{\text{run}} =\frac{-1}{1} =-1[/tex]

The slope is -1.

Cool fact:  You'll get the same value if you use any two points on the line.

There is a right triangle formed by legs 15 and 8, with radius r being the hypotenuse.

The half-life of a radioactive kind of neodymium is 11 days. If you start with 2,616 grams of it, how much will be left after 22 days?

Answers

Answer:

654 grams

Step-by-step explanation:

When you set up this equation you want the number of grams you start with, 2616, and the factor by which it is decreasing, which is half, or 1/2. Because the half life is 11 days, but you want to find the amount left over after 22 days, you can make 22/11 as the exponent on the 1/2. The equation should look like this : 2616(1/2)^22/11. With these kinds of equations you always want to multiply the starting value by the factor of increase/decrease, and raise that factor to the time eclipsed divided by the set time(like the 11 day half life).

Elena can make 15 pizzas in 3 hours. If the number of pizzas is represented by p and time is represented by t, Write an equation that shows the total number of pizzas made in terms of time.

p = 5t

3t = 15p

p/t = 15

p = 1/5t

Answers

p divided by t = 15 divided by 3 =5 if you have to divide 15 by 3 to see how many pizza´s can be made in 1 hour.
15 pizza's represents p and 3 hours represents t then it will be p divided by t.

Answer:

p = 5t

Step-by-step explanation:

We'll check by plugging in t = 3 and p has to equal 15

p = 5t     ✅

p = 5(3)

p = 15

3t = 15p ❌

3(3) = 15p

9 = 15p

p = 15/9 = 5/3

p/t = 15 ❌

p/3 = 15

p = 45

p = 1/5t ❌

p = 1/5(3)

p = 3/5

Ms. Carey grades 4 tests during her lunch. She grades 1/3 of the remainder after school. If she syill5has 16 test to grade after school, how many test are there?
​

Answers

Answer: 24 tests

Step-by-step explanation:

Ms. Carey graded 1/3 of the tests and still had 16 tests to go.

This means that the 16 tests represent the remaining proportion of the total number of tests:

= 1 - 1/3

= 2/3

2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:

2/3x = 16

x = 16 ÷ 2/3

x = 16 * 3/2

x = 24 tests

Answers

Answer:

the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15

Step-by-step explanation:

the mode is 5 and 2 because they both occur the most often

The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5

the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25

the range is 15 because the range is the diff between the highest and lowest value
