Answer:

99 votes for ice cream

Step-by-step explanation:

4 + 11 + 8 + 7 = 30

270/30 = 9

to find the predictions multiply the votes by 9

ice cream has 11 votes

11 * 9 = 99

Answer 2

Answer:

99

Step-by-step explanation:

Add up total amount of votes

4+11+8+7 = 30

270/30 = 90

Set up ratio

11/30 = x/270

cross multiply

30x = 2970

divide both sides by 30 to get x by itself

x = 99

Jose's school is 4 km away. He walked 30 min at 5 km/hr when he realized he was running late and started running. How fast does he need to to make it to school before the bell rings in 15 minutes.

Answers

Answer:

Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15  minutes before the bell rings.

Step-by-step explanation:

Total distance from home to School [tex]= 4[/tex] km

Distance travelled by Jose in first [tex]30[/tex] minutes is equal to

[tex]\frac{30}{60} * 5\\= 2.5[/tex]

Distance to travel in next [tex]15[/tex] minutes is equal to

[tex]4 -2.5 = 1.5[/tex] Km

Required speed

[tex]\frac{1.5}{\frac{15}{16} } \\= 1.5 * 4\\= 6[/tex]

Jose need to travel with a speed of [tex]6[/tex] Km/hr to reach school in 15  minutes before the bell rings.

Answers

Answer:

no

Step-by-step explanation:

The correct explanation is A

[tex]\frac{x^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex]

Thus

[tex]\frac{9.2}{4}[/tex] × [tex]\frac{10^{8} }{10^{-3} }[/tex]

Rewrite: x² -7x +4x -28

Grouping: (x² -7x) +(4x -28) = x(x -7) +4(x -7) = (x +4)(x -7)

Step-by-step explanation:

The given quadratic is ...

... x² -3x -28 . . . . . a=1, b=-3, c=-28

a) The value at the top of the X diagram is the product a·c = 1·(-28) = -28.

The value at the bottom of the X diagram is the coefficient b = -3.

The values on the sides of the diagram are the factors of -28 that add up to make -3. These are -7 and 4. That is, ...

(-7)·(4) = -28

(-7)+(4) = -3

b) Since the two values on the sides of the diagram add up to give "b", the value of "b" in the equation can be rewritten as the sum of these two numbers. Doing that, we have ...

... x² -3x -28

... = x² +(-7+4)x -28

... = x² -7x +4x -28 . . . . . . order does not matter. It could also be x² +4x -7x -28

c) We can group pairs of terms in the rewritten expression and factor each pair.

... = (x² -7x) +(4x -28) . . . . . first pair has a common factor of x; second pair, 4

... = x(x -7) +4(x -7) . . . . . . . these terms now have a common factor: (x -7)

... = (x +4)(x -7) . . . . . . . . . . the complete factorization of x² -3x -28

Comment on extended application

When a ≠ 1, there are a couple of additional steps. Effectively, you reduce the fractions ax/p and ax/q to a'x/p' and a''x/q'', then rewrite those as the factors (a'x+p')(a''x+q'') where the ' and '' numbers are after reducing the fractions. (The numbers may be the same as the original if the fraction cannot be reduced.) As a check, a'·a'' = a, and p'·q'' = c.

Cinemark is having a summer special.If you get a membership one-time cost is $12.50 plus $2.00 per movie that you watch.Write a linear equation that will show the cost of membership and each movie seen

Answers

Answer:

Y=12.50x+2.00

Step-by-step explanation:

The linear equation that will show the cost of membership and each movie seen will be C = 2n + 12.5.

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Cinemark is having a summer special. If you get a membership one-time cost is $12.50 plus $2.00 per movie that you watch.

The slope of the line is $2.00 and the y-intercept of the line is $12.50.

Let C be the total cost and n be the number of movies. Then the linear equation will be

C = 2n + 12.5

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?

Answers

Answer:

The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.

Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.

Step-by-step explanation:

First let's find the area:

5x² × 12x

= 60x³

Now the perimeter:

2(5x² + 12x)

= 10x² + 24x

At Silver Gym, membership is $40 per month, and personal training sessions are $35 each. At Fit Factor, membership is $60 per month, and personal training sessions are $25 each. In one month, how many personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?

Answers

Answer:

Let there be x training sessions at both the gyms.

At silver gym,

Total cost = membership + personal training session

= 25+45x ...(1)

At Fit Factor,

Total cost = 85+35x ....(2)

If the total cost at the two gyms equal,

25+45x=85+35x

Taking like terms together,

45x-35x=85-25

10x=60

x = 6

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the salary Alex for semi-month be x,
Salary for a month would be = 2x
Now, his salary for the year is equal to 12 * 2x
Now,
accoding to the question,
y = 12*2x
y = 24x

Thus, the required algebraic expression for Alex's salary annually is 24x.
