Answer: 53.5
Step-by-step explanation:
To determine the average of any group of numbers
You must first add them all together
Then you must divide the sum by the amount of number in the group
In this case, we have 2 numbers
So let's add them
66 + 41 = 107
Now divide 107 by 2
107/2 =53.5
April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars , while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?
Step-by-step explanation:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Answer:
April: 4x+6y=16.5
Bill: 4x+3y=11.25
solving the two equations simultaneously will give you y=1.75

Which set of side lengths will form a right triangle?

9, 24, 25
Answer:
7, 24, 25
Step-by-step explanation:
Answer: [tex]7, 24, 25[/tex]
Step-by-step explanation:
Hi there!
We can solve this using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, a^2 + b^2 = c^2. We can plug each set of numbers into the equation, one by one, to see if the set of numbers is true in the equation. One thing to note is that the largest number out of the set is always the hypotenuse, or c. The other numbers are the legs (a and b.)
5, 11, 13
a^2 + b^2 = c^2
(5)^2 + (11)^2 = (13)^2
25 + 121 = 169
146 ≠ 169
Since 146 doesn't equal 169, this is NOT a right triangle
9, 24, 25 a^2 + b^2 = c^2 (9)^2 + (24)^2 = (25)^2 81 + 576 = 625 657 ≠ 625
Since 657 doesn't equal 625, this is NOT a right triangle
7, 24, 25 a^2 + b^2 = c^2 (7)^2 + (24)^2 = (25)^2 49 + 576 = 625 625 = 625
This equation is true, because 625 = 625. Therefore this IS a right triangle.
What’s the answer??????
Answer:
x=50
Step-by-step explanation:
Answer:
x = 50
Step-by-step explanation:
So the equation is 2x+25=125. you first subtract the 25 from the 125 which you'll get 100 and then divided by 2 which leaves the x alone and so 100/2 = 50 so x= 50

what is the height from the base of the statue to the tortch in inches
Answer: OK so I think Her Size (In a case like this it's ok to ask her size without getting in any trouble.): Her total overall height from the base of the pedestal foundation to the tip of the torch is 305 feet, 6 inches. Height of the Statue from her heel to the top of her head is 111 feet, 6 inches.
Step-by-step explanation:
This should be a simple problem, I think, simple calculate changing the feet to inches or yards, as the problem demands. I believe the height would be 1,813 inches (12 inches per foot), and the thickness of the arm would be 4 yards (3 feet per yard).

The graph shows the total cost of a zoo membership for family. which equation can be used to find the total cost y for any number of family members X?
A. y= 10x
B. y= 25x
C. y= 10x +25
D. y= 25x +10
Answer:
the answer is c
Step-by-step explanation:
cause math
Answer:
Answer is C. y = 10x + 25
Step-by-step explanation:
This equation is in the form y = mx + b
we all know b is the y-intercept (where the line passes y axis)
When we look at the graph, we see that the line passes through y-axis at 25 which means our b is 25.
If we plug 25 in place of b in y = mx + b, C is the only option that makes sense
Round 94584 to the nearest hundreds
Answer:
94600
Step-by-step explanation:
A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.
Jorge is building a circular stage for an upcoming concert. The stage needs to have an area of at
least 200 square meters to fit the performers. What is the smallest radius that the stage could have? Explain your reasoning,
Answer:
The smallest radius that the stage could have is 7.97 m.
Step-by-step explanation:
The stage needs to have an area of at least 200 square meters to fit the performers.
For a circle, the area is given by :
[tex]A=\pi r^2[/tex]
such that,
[tex]\pi r^2=200\\\\r=\sqrt{\dfrac{200}{\pi}} \\\\r=7.97\ m[/tex]
So, the smallest radius that the stage could have is 7.97 m.

Answer:
y=-⅔+5
Step-by-step explanation:
using the slope formula we can figure out the slope is -4/6
using point slope formula (y-y1=m(x-x1))
y-7=-4/6(x--3)
y-7=-4/6x-2
y=-4/6x+5
Answer:
y=-3x-24
Step-by-step explanation:
(-3,7) (3,-11)
-11-7 = -18
3-(-3)= 6
-18/6= -3
y=-3x+?
b= y-3x
b= -3-3*(7)
b= -3 - 21
b= -24

What is the variance of the data set (4,6,7,10)
Answer:
4.6875Step-by-step explanation:
Given data set
(4,6,7,10)To find
VarianceSolution
The Variance is defined as the average of the squared differences from the mean.The mean is:
x = (4 + 6 + 7 + 10)/4 = 6.75The variance is:
σ² = [(4 - 6,75)² + (6 - 6.75)² + (7 - 6.75)² + (10 - 6.75)²]/4 = 4.6875The number of people y (in millions) who have a driver's license can be estimated by the linear equation y=2.3x+190, where x is the number of years after 2000.
y=2.3x+190
y= 95.

James wants to compete in the international speed texting competition next year where participants compete on text speed and accuracy. James's current text speed is 2 characters per second. James has found that his texting speed is increasing at a rate of ½ a character per second for each month that he practices.
Complete question :
James wants to compete in the international speed texting competition next year where participants compete on text speed and accuracy. James’s current text speed is 2 characters per second. James has found that his texting speed increases at a rate of 1⁄2 a character per second for each month that he practices.
1. a. What is James’s new texting speed if he practices for only 1 month? __________
b. What is James’s new texting speed if he practices for 2 months? ____________
c. What is his new texting speed if he practices for 3 months? _____________
d. Write an algebraic equation that gives James’s texting speed s for m months of
practice.
Answer:
2 1/2 ; 3, 3 1/2 ; s = 2 + 1/2m
Step-by-step explanation:
Given that :
Speed = 2 characters per second
Rate of change = 1/2 character per second increase per month
New texting speed after 1 month :
Initial speed + (change per month * number of months)
2 + 1/2 * 1
= 2 1/2 or 2.5
After 2 months :
Initial speed + (change per month * number of months)
2 + (1/2 * 2)
2 + 1
= 3 characters per second :
After 3 months :
Initial speed + (change per month * number of months)
2 + 1/2 * 3
= 2 + 1.5
= 3.5
For the algebraic equation :
New texting speed, s
Number of months, m
Initial speed + (change per month * number of months)
s = 2 + 1/2 * m
s = 2 + 1/2m
Which of the following could be the graph of the line y = 3x - 2?
You didn't give a graph but I will visualize what it looks like for you.
The line is going through (0,-2) because that is the y-intercept.
The line has a slope of 3.
So, the line goes through:
(1,1)
(2,4)
(3,7)
(4,10)
(5,13)
Since there is no picture provided, I can't give you the answer, but I can help you solve it.
To solve this you have to first look at the b part of the formula y=mx+b, so -2.
Then, you can find -2 on the y-axis (the vertical axis)
and then you could move upwards 3 spaces, then right 1 space.
You would do this as the slope is 3/1 (the mx part of the equation).
Finally, you continue to move up 3, and right 1 until there are enough points on the graph to make a line, and that will help you see what graph is correct.
It should look something like this:

im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]
