Alexa has 36 friends

Step-by-step explanation:

80 - 8 = 72, if she gives 2 to each friend...

that would mean 2 · x = 72

to find x, divide 72 by 2,

72 ÷ 2 = 36 friends

Answer:

Ingreso total= $110

Step-by-step explanation:

Dada la siguiente inforación:

Cantidad de paletas vendidas= 14

Precio de venta unitario= $8

Para calcular el ingreso total, debemos usar la siguiente formula:

Ingreso total= precio*cantidad

Ingreso total= 8*14

Ingreso total= $112

Redondeado a la decena más cercana:

Ingreso total= $110

Answer:

C) 60 ft

Step-by-step explanation:

From any dot in the graph you can figure out the speed.

Let's take the one at 2 minutes, because it is on a grid point.

That one tells us that in 2 minutes, the animal travels 40 feet.

That means in 1 minute, it travels half that, i.e., 20 feet.

So in 3 minutes it will travel 20*3=60 feet.

Answer:

x=25

Step-by-step explanation:

180-60=120

35+120+x=180

x=25

Answer:

The answer is 61.

Step-by-step explanation:

Let, the numbers are: x, (x+2), (x+4)

Now, x+x+2+x+4 = 183

3x + 6 = 183

3x = 177

x = 59

So, second number would be: (x+2) = (59+2) = 61

Answer:

Step-by-step explanation:

n+(n+2)+(n+4)=183

3n+6=183

3n=177

n=59

So the three numbers are 59, 61, and 63.

Answer:

c = 202 children use the pool, and 284 - 202, or 82 adults.

Step-by-step explanation:

Represent the number of children by c and the number of adults by a.

There are a total of 284 people using the pool, so c + a = 284.

Admission fees are $1.50/child and $2.00/adult.  $1.50c is the amount taken in through ticket sales for c children;  $2.00a for adults.

Then total ticket sales are ($1.50/child)c + ($2.00/adult)a = $467.

Going back to c + a = 284, a = 284 - c, and so the above equation becomes

($1.50/child)c + ($2.00/adult)(284 - c) = $467

After simplifying this equation in c, we get:

1.50c + 568 - 2c = 467, or

101 = 0.5c.  Thus, c = 202 children use the pool, and 284 - 202, or 82 adults.

Answer:

[tex]5z^3\sqrt{42}[/tex]

Step-by-step explanation:

You can multiply and put everything under one square root to get [tex]\sqrt{1050z^6}[/tex]. You can take out [tex](5z^3)^2[/tex] from the square root to get [tex]\boxed{5z^3\sqrt{42}}[/tex]

Answer:

1 kilometer is 1000 meters

1 hectometer is 100 meters

1 dekameter is 10 meters

1 meter is 1 meter

1 decimeter is 0.1 meters

1 millimeter is 0.001 meters

Answer:

1 kilometer = 1000 meters

1 hectometer = 100 meters

1 dekameter = 10 meters

1 meter = 1 meter

1 decimeter = .1 meter

1 centmeter = .01 meter

1 milimeter = .001

Explanation:

You need to convert those units to other units, the most common way is to have a table with different factors. I would recommend the one of cm, mt, km, m/h. You can find those on internet.

The number of visitors after 5 months:

Answer:

i believe the answer is 25.

Step-by-step explanation:

this is because if a=how much money deposited after  t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.

tell me if this is incorrect.

Answer:

25

Step-by-step explanation:

In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.

Answer:

[tex]\frac{3}{8}[/tex] which is less and 1 and 1/4

Step-by-step explanation:

They have 2 pizzas to start

They ate 1 full pizza and then 1/8 of another. This leaves 7/8 left

They then ate another 1/2 of a pizza. (1/2 also is 4/8)

The Lower common domonitor of the the two is 8. To get 8 from the two you multiply by 4.

So you end up with

[tex]\frac{1}{2} * 4 = \frac{4}{8}[/tex]

So now you can subtract and get

[tex]\frac{7}{8} - \frac{4}{8}[/tex]

which the dominator remains the same and you only subtract 7-4 = 3

So your answer is

[tex]\frac{3}{8}[/tex]

Answer:

yes

Step-by-step explanation:

14y-8=13

We add 8 on both sides to cancel it out and add it to 13.

14y-8=13

    +8  +8

14y=21

Now we divide 14 on both sides to cancel it out, separate it from the y, and to divide it from 21.

14y=21

/14  /14

y=1.5

---

hope it helps

Answer:

Add 8 to both sides of the equation to get 14y=21

Divide both sides of the equation by 14 to get y= 1.5

Answer:

45 degrees

Step-by-step explanation:

Before we start, it is important to know that the sum of all angles of a triangle adds up to 180. Since one of the angle measure is already given to us, 90, we can subtract this from 180.

180-90=90

This tells us that the two remaining angles will add together to equal 90. In addition, it also tells us that the two remaining angles are equal. This means we can divide 90 by 2, and it leaves us that x= 45 degrees.
