Answer:
d = 5
Step-by-step explanation:
d = √ (X2 - X1)^2 + (Y2 - Y1)^2
d= √ (-3 - -7)^2 + (1 - -2)^2
d= √ (4)^2 + (3)^2
d = √16 + 9
d = √25
d = 5
On a certain hot summers day 284 people use the public swimming pool the daily prices are $1.50 for children and two dollars for adults their seats for admission total of $467 how many children and how many adult swim at the public pool that day
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:
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.

Alexa won 80 super bouncy balls playing horseshoes at her school's game night. Later, she gave two to each of her friends.
She only has 8 remaining. How many friends does she have?
Answer:
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

The sum of 3 consecutive odd numbers is 183 ?
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.
What is the minimum value of the function over the interval -5 < x < 5?
h(x) = log[(x – 3)^2 + 2]
Answer: ln(2)
Step-by-step explanation:
In order to minimize ln[(x – 3)^2 + 2], we have to minimize [(x – 3)^2 + 2] since natural log is an increasing function
For that, it suffices to minimize (x – 3)^2, which is non-negative for all real numbers x
As such, the minimum value is achieved when x - 3 = 0; - 5 < 3 < 5
Substitute x = 3 in the original equation to get ln(2)
anyone have the answer to this?

Find the value of x.
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.

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.
The Graf family made two pizzas. They ate 1 and 1/8 pizza before watching a movie, and 1/2 pizza more after the movie. What is a reasonable estimate for the amount of pizza left
A) Less than 1 1/4
B) More than 1/2
C) Less than 1/3
D) More than 1 1/4
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]

The graph represents the number y of visitors to a new art gallery after x months. Write an exponential function that represents this situation. Approximate the number of visitors, to the nearest person, after 5 months.
Y=____
About ___ visitors
Answer:
y = 40(1.5)ˣAbout 304 visitorsStep-by-step explanation:
Formula for exponential function:
y = abˣUse two points from the graph to determine the function:
(0, 40) and (1, 60)Substitute the coordinates and work out the values of a and b:
40 = ab⁰ ⇒ 40 = a60 = ab¹ ⇒ 60 = ab ⇒ 60 = 40b ⇒ b = 60/40 ⇒ b = 1.5The function is:
y = 40(1.5)ˣThe number of visitors after 5 months:

14y-8=13 plssss helpp
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:
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.
