Answers

Answer 1

Answer:

77.5

Step-by-step explanation:

Given:

Scores: 65, 70, 75, 80, 85, 90, 95

Number of Students: 8, 5, 3, 6, 6, 4, 2

Step 1: Calculate the sum

Sum = (65 * 8) + (70 * 5) + (75 * 3) + (80 * 6) + (85 * 6) + (90 * 4) + (95 * 2)

= 520 + 350 + 225 + 480 + 510 + 360 + 190

= 2635

Step 2: Calculate the mean

Mean = Sum / Total Number of Students

= 2635 / (8 + 5 + 3 + 6 + 6 + 4 + 2)

= 2635 / 34

≈ 77.5

Jada’s babysitter is times Jada’s current age. In 5 years, Jada will be her
babysitter’s current age.
How many years old is Jada now?

Answers

Answer:

5 years old.

Step-by-step explanation:

Let's call Jada's current age "J" and the babysitter's current age "B".

From the information given, we know:

B = J (Jada's babysitter is J times Jada's current age)

J + 5 = B (In 5 years, Jada will be her babysitter's current age)

By substituting the first equation into the second equation:

J + 5 = J

5 = J

Therefore, Jada is currently 5 years old.

5 years old there you go

Answers

Answer: $10

Step-by-step explanation:Let the money spent by each friend = $x

Number of persons including Donovan = 4

Total amount spent by all friends all together = $4x

Since each spent half of their money on rides so amount spent on rides =  = $2x

Then they each spent $3 on food so total money spent = $(2x + 12)

Remaining money = $8

Now the equation will be

$4x - $(2x + 12) = $8

4x - 2x - 12 = 8

2x - 12 = 8

2x = 12 + 8

x = $10

Therefore, each friend spent $10.

The answer to this question is x=$10

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5
