Answer:

-1.9

Step-by-step explanation:

Notice that the point is on the left of -1.5, it has to be less than -1.5. The only numbers smaller than -1.5 that are give are either -4, or -1.9. Since the point "B" is not that far away from -1.5, it can't have the value of -4, thus the answer is -1.9.

Hope this helps, Good Luck!

Answer:

.25q+.10d=25.10

q+d=128

Step-by-step explanation:

Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.

Volume = 49.7pi

The volume of a cone can be found with the following equation

[tex]V = r^2\frac{h}{3} \pi[/tex]

From here we can solve the equation

[tex]V = 3.4^2\frac{12.9}{3} \pi \\V = 11.56 * 4.3 \pi \\V = 49.7 \pi[/tex]

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend

27ft  :   4.5ft

?      :   5ft

Formula given divided by the original or missing value equivalent

g/o = 5/4.5 = 1.11111 multiplier

Then use multiplier for the tree given value.

27 x 1.111111 = 29.999997

= 30ft

Answer:

D

Step-by-step explanation:

The symbol, ≥, represents at or greater than the amount on the right side. This means the balance must be at or greater than $500.

Answer:

0 < x ≤ 1 would be f(x) = 1

1 ≤ x ≤ 2 would be f(x) = x

2 < x ≤ 3 would be f(x) = 3

3 < x ≤ 4 would be f(x) = 4

step-by-step explanation:

0 < x ≤ 1 is over the line 1

1 ≤ x ≤ 2 x is the slope of 1

2 < x ≤ 3 is over the line 3

3 < x ≤ 4 is over the line 4

Step-by-step explanation:

Answer:

Answers above are correct for Plato/Edmentum users

1 ≤ x ≤ 2 = f(x) = x

0 < x ≤ 1 = f(x) = 1

3 < x ≤ 4 = f(x) = 4

2 < x ≤ 3 = f (x) = 3

Answer:

total amount of tickets for the rides: 21+32+31=84

total amount of tickets she has: 23-6= 17

total amount of tickets she needs left: 84-17=67

answer: 67

Hope this helped :) have a great rest of your day or evening!!!

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

She need 67 more tickets.

The sum of cost of all rides = 84

She had 23, but she lost 6... so now she only have 17,

so 84 – 17 = 67

and it's ur answer

Answer:

There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.

Step-by-step explanation:

The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books.  So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

Part A: Shiloh would collect data on which student spends the most time at the beach

Part B: It is a statistical question

Part A I would expect her to collect a certain number of times, such as each dot 1 hour. Part B This is a statistical question.

Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.

Part A: we have to describe the data you would expect her to collect from this question.

I would expect her to collect a certain number of times, such as each dot 1 hour.

For example, if she had a dot plot or a chart to divide how much time each student stays at the beach, along with her collecting the students' names to figure out the answer to her question.

Part B:  Explain whether this is a statistical question. If this is not a statistical question, then modify the question to make it statistical.

This is a statistical question.

A statistical question is a question that can be solved by collecting data that varies.

To even solve this, we need to collect data. The easiest way to solve this is with a dot plot. we also need the student's data, such as their names and how many hours at the beach they spent time there.

Answer:

Step-by-step explanation:

If you add 80+50 you get 130 and if you subtract that from 180 you get 50

and a isoceles has 2 equla angles

Answer:

Step-by-step explanation:

a) Let the width = w

Two times its width = 2*w = 2w

9 inches less than 2w = 2w - 9

Length = 2w - 9

Area of rectangle = length *width = 180 square inches

(2w - 9 ) * w = 180

2w*w - 9*w = 180

2w² - 9w - 180 = 0

b) sum = -9

Product= -360

Factors  = -24 , 15    {15 *[-24] = -360 and 15 + (-24) = -9 }

2w² - 9w - 180 = 0

2w² - 24w + 15w - 180 = 0

2w(w - 12w) + 15(w - 12) = 0

(w -12) (2w + 15) = 0

{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}

w - 12 = 0

w = 12 inches

l = 2w -9

 = 2*12 - 9

= 24 - 9

l = 15

length = 15 inches

Width = 12 inches

c) Perimeter = 2 *(length + width)

                     = 2*(15 + 12)

                     = 2 * 27

                     = 54  inches

Answer:

so for the first problem, you round to ten since the one place is a nine. for the second one, your round to 67 since the decimal point is 9. for the third one, you round to 100 since it's 94 and anything above 50 rounds to 100. fo the fourth one round to 9 since the decimal point is a 2. for the fifth one you round to 40 since the one's place is a well...1.

Step-by-step explanation:

okay so as we know when the number is over 5 we round up. so for the sixth problem we can see it says we round to nearest whole number meaning the ones place. now when we round we look to the number on the right. in this case its the one on the other side of the decimal point. Which if we see is a 4, which is less than 5 so orund down to 9.
