Answer 1

Jenny is 8 and Sammie is 17.

Let's use j for Jenny and s for Sammie.

Given that Jenny is 9 years younger than Sammie, j = s + 9. Five years ago, Sammie was 4 times older than Jennie, 4(j - 5) = (s - 5).

We'll substitute the value of x from equation 1 in equation 2:

4(s - 9 - 5) = (s - 5)

3s = 51

s = 17

Then, we plug in what we just learned for j = s - 9. This gives us 17 = s - 9, which means that j = 8, because 8 + 9 = 17.

Therefore, Jenny is 8 years old and Sammie 17 is years old.

I liked the Phineas and Ferb reference lol :) Happy to help, have a good day!

Adrian is throwing a ball into a pail. With 50 attempts, the ball goes into the pail and stays 8 times, goes into the pail and bounces out 6 times, and misses the pail 36 times. If Adrian throws the ball again, what is the probability of each outcome?
Probability the ball goes into the pail and stays =
Probability the ball goes into the pail and bounces out =
Probability the ball misses the pail =

Answers

The probability the ball goes into the pail and stays in is 16%

The probability the ball goes in to the pail and bounces out is 12%

The probability the ball misses the pail is 72%

STEPS:
Divide each number by 50.
36 divided by 50: 0.72
6 divided by 50: 0.12
8 divided by 50: 0.16

Remove the 0’s from the numbers
0.72 -> 72
0.12 -> 12
0.16 -> 16

We want to make sure that all these numbers equal 100 because 100% is 50 in this equation.
12 + 16 + 72 = 100
Because those numbers equal 100, 50 is equal to 100%

Hope this helps!

Answer:

The approximate probability that the ball goes into the pail and stays is 8/50 or 4/25.The approximate probability that the ball goes into the pail and bounces out is 6/50 or 3/25. The approximate probability that the ball misses the pail is 36/50 or 18/25.

Step-by-step explanation:

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed. It is based on the results of an experiment or a simulation. For example, if you toss a coin 10 times and get 7 heads and 3 tails, the experimental probability of getting heads is 7/10 = 0.7. This may not match the theoretical probability of getting heads, which is 1/2 = 0.5, because of random variation or error. The more trials you perform, the closer the experimental probability will get to the theoretical probability.

To find the probability of each outcome, we need to divide the number of times the outcome occurred by the total number of trials. Using the given data, we can calculate the probabilities as follows:

The probability the ball goes into the pail and stays = 8/50 = 0.16 The probability the ball goes into the pail and bounces out = 6/50 = 0.12 The probability the ball misses the pail = 36/50 = 0.72

We can check that these probabilities add up to 1, which means they are valid.

Step-by-step explanation:

The "||" signs around the numbers indicate absolute value.

Absolute value is how far a number is from 0. Ex. The absolute value of -7 would be 7, because -7 is 7 numbers away from 0.

So in these problems, we are taking the absolute values of each number. We will also be using PEMDAS because there are multiple operations in each problem.

2 × | 12 | - | -7 | = 17

| -108 | ÷ | 36 | + | 17 | = 20

| -5 | × | 12 | - | 5 | × | -12 | = 0

Step-by-step explanation:

(a negative number will become positive if it's in these brackets: |-12|= 12)

2 × | 12 | - | -7 | =

2 × 12 - 7 = (-7 becomes positive seven, +7)

24 - 7 = 17

| -108 | ÷ | 36 | + | 17 | =

108 ÷ 36 + 17 = (-108 becomes positive one hundred and eight, +108)

Help pls. Also wdym this is to short yk why so long >:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

EASY MATH QUESTION, EARN POINTS!

Answers

Answer:

g43 = 79.5

Step-by-step explanation:

geometric sequence = ar^(n-1), where a is first term and r is common ratio.

g23 = ar^(23-1) = ar^22 = 16.

g28 = ar^27 = 24.

now do g28/g23:

(ar^27) / (ar^22) = 24/16,

a^(1-1) r^(27-22) = 24/16,

a^0 r^5 = 24/16,

r^5 = 24/16 = 1.5,

r = (1.5)^1/5 ≈ 1.084.

ar^22 = 16,

a = 16/(r^22) ≈ 2.687.

so g43 = ar^42 ≈ (2.687)(1.084)^42 = 79.5

g43=79.5 I’m pretty sure

solve for t

7t–8=10+2t

Answers

Answer:

t=18/5

Step-by-step explanation:

7t-8=10+2t

+8 on both sides

7t-8+8=10+2t+8

combine like terms

7t=18+2t

-2t on both sides

7t-2t=18t+2t-2t

combine like terms

5t=18

divide by 5

5t/5=18/5

t=18/5

Add 8 to both sides:

7t=18+2t

Subtract 2t from both sides:

5t=18

Divide both sides by 5:

t=18/5

t=3.6
