can anyone please help me with this I'm not good at math ​

Answers

answer: -1/13

slope: (y2-y1)/(x2-x1). So (12-7)/(-39-26). Simplify that and you get 5/-65, which, simplified, is 1/-13.

Answer:

The correct answer is -1/13

2, Jasper withdrew $45.00 from her savings account. She then used her debit card to buy groceries for $30.15, and then deposited a check for $14.65. What was the total amount of change in Jasper’s account?

Answers

1. 43.75 6. No table 2. 15.50 I think

1. Answer/Step-by-step explanation:

Diving question: 0 - 35.25 + -8.5 = -43.75 below sea level

Baking question: insolvable by lack of information.

2. Answer/Step-by-step explanation:

A money decrease of $60.50 (or -60.50 increase and change)

? - 45 - 30.15 + 14.65 = -60.50

Since we are finding the change it is best to replace the question mark with 0 so that it is easier to solve.

0 - 45 = -45

-45 - 30.15 = -75.25

-75.25 + 14.65 = -60.50

Find the arc length on a circle with radius =4 inches and central angle of 30°

Answers

Answer:

Step-by-step explanation:

I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:

[tex]AL=\frac{\theta}{360}*2\pi r[/tex]

Our angle is 30 and our radius is 4, so we fill in accordingly:

[tex]AL=\frac{30}{360}*2(3.1415)(4)[/tex] (this is if you multiply in pi. We'll find the answer in terms of pi as well).

AL = [tex]\frac{1}{12}*25.132[/tex] and

AL = 2.09433 inches

In terms of pi, the answer would be

AL = [tex]\frac{2}{3}\pi[/tex] inches

student. a. Solve the inequality and interpret what your solution means. b. Can

Answer:

A. t= 4.1

B. No because t = 4.1 and if you do 6.5 divided by 1.5 then you get 4.3 and that won't work.

and orange for your second? (if you ARE replacing it) *
1/75
2/75
10/625
16/625

Answers

Answer:

16/625

Step-by-step explanation:

Step one:

sample space

A bag contains

5 cherry,

8 orange,

2 grape,

7 bubblegum, and

3 apple  lollipops.

sample size= 5+8+2+7+3= 25

Required:

The probability of choosing grape for your first lollipop

and orange for your second?

1. The probability of choosing the grapes lollipops

=2/25

2. the probability of choosing the orange  lollipops----Note in the second choice the sample size will reduce because the first choice was done with out a replacement

=8/24

The total is

2/25*8/25= 16/625

PLEASE HELP ME I WILL MARK U AS THE BRAINIEST ANSWER!

Answers

Answer:

(21, 8)

(3, 2)

(-15, -4)

Step-by-step explanation:

First we need to create the equation in y=mx +b form.

(m) is slope [rise/run]

(b) is y intercept

The line crosses the y axis at (0,1) so that's our (b) and to find slope we will find a point where ethe line crosses a point, I'll use (0, 1) and see how many it has to go to reach the next point. In this case it has to go up 1, and right 3.

Our slope is 1/3.

y=1/3x+1.

Now we can start applying the given points.

(21, 8)

8=1/3(21)+1

8=7+1

8=8.

(21, 8) is a solution.

(3, 2)

2=1/3(3)+1

2=1+1

2=2

(3, 2) is a solution.

(-15, -4)

-4=1/3(-15)+1

-4=-5+1

-4=-4

(-15, -4) is a solution.

(12, 9)

9=1/3(12)+1

9=4+1

9=5

(12, 9) is not a solution.

(-6, 1)

1=1/3(-6)+1

1=-2+1

1=-1

(-6, 1) is not a solution.
