Answer:
19.55 $
Step-by-step explanation:
3.45$×10=34.5=150% of his money overall
34.5÷3=11.5
11.5×2=23= 100% of his money
23-15%=19.55$
$23
Step-by-step explanation:
15% of x = 3.45
= 15/100 = 3.45/x
x= 23

Answer:
day 8
Step-by-step explanation:
the rate of change is 2 (x2) which is making the amount saved double each day you can write a formula to represent this sequence:
f(n)=0.01x2^n-1
you put in the day number for n
f(n)=0.01x2^8-1
this gives you 1.28 which is the first day with an amount above 1.00

The volume of a cylinder is 64 cubic feet, and the height of the cylinder is 8 feet. What is the radius of the cylinder?
Answer:
V = pi R^2 * h volume of cylinder (area of base * height)
pi R^2 = 64 / 8 = 8
R^2 = 8 / pi = 2.865
R = 1.69 ft

The two angles are not equal
Madison lives between Anoa and Jamie as depicted on the line segment. The distance between Anoa's house and Madison's house is represented by 3x+2 miles, the distance between Madison's house and Jamie's house is represented by 3x+4 miles, and the distance between Anoa's house and Jamies house is represnted by 9x-3 miles. Find the value of x. Then find the distance between Madison's house and Jamie's house.
Answer:
x = 3
13 miles between Madison and Jamie's house.
Step-by-step explanation:
If we add the distance between Anoa's and Madison's house with the distance between Jamie's and Madison's house, then we get the total distance between Anoa's and Jamie's house.
(3x + 2) + (3x + 4) = 9x - 3
Let's add up the terms first
3x + 2 + 3x + 4 = 9x - 3
6x + 6 = 9x - 3
Let's move the variables to the right side by subtract 6x from both sides
6x + 6 = 9x - 3
-6x -6x
6 = 3x - 3
Add 3 to both sides
6 = 3x - 3
+3 +3
9 = 3x
Isolate the variable, x, by dividing both sides by the coefficient, 3.
9/3 = 3x/3
x = 3
Now we need to find the distance between Madison's and Jamie's house.
3x + 4
Plug in 3 in place of the x
3(3) + 4
9 + 4 = 13
Answer:
Step-by-step explanation:
If we add the distance between Anoa's and Madison's house with the distance between Jamie's and Madison's house,then we get the total distance between anoa's and Jamie's house.

Which transformation were used to fcreate traianglemA’ B’ C?
9514 1404 393
Answer:
(b) dilation by 2, reflection in y-axis
Step-by-step explanation:
Each of the dimensions of ΔA'B'C' is double the corresponding dimension of ΔABC, so dilation by a factor of 2 has occurred.
The sequence of vertices in ΔA'B'C' is CCW, opposite that of ΔABC. Hence, a reflection has taken place. (Rotation keeps the same order.)
The transformation is a dilation by a factor of 2 and a reflection across the y-axis.

use the substitution method to solve the sstem of equations choose the correct ordered pair 2x-y=10 and 2x-2y=4
Answer:
(8, 6)
Step-by-step explanation:
2x - y = 10
2x - 2y = 4
=>
x - y = 2
x = y + 2
we put that into the first equation
2×(y+2) - y = 10
2y + 4 - y = 10
y + 4 = 10
y = 6
=>
x = y + 2 = 6 + 2 = 8
so, we have a ordered pair (x, y) = (8, 6)
If several points are graphed on a number line, is the point that is the farthest from 0 always the greatest?
Answer:
If several points are graphed on a number line, the point that is farthest from 0 need NOT be always greater. Consider x axis, our Real number line. We can traverse in positive number direction and negative number direction.

In store A: A box of cotton candy costs 1 dollar, 12 boxes cost 12 dollars. In store B: 12 boxes cost 48 dollars. How much does each box cost in store B?
Answer:
$4Step-by-step explanation:
To find the cost of each box divide the total cost by the number of boxes:
48/12 = 4In store A:
→ A box of cotton candy cost = $ 1
→ 12 boxes cost = $ 12
In store B:
→ 12 boxes cost = $ 48
Now we have to,
find the cost of each box in the store B.
→ Total cost in B ÷ Total boxes in B
→ 48 ÷ 12 = 4
So, $ 4 is cost of each box in store B.

WHY DOES NO ONE ANSWER MY QUESTIONS?? Its kinda annoying that i answer others' questions but no one answers mine. Well if anyone feels like helping me heres my question:
A mathematician reported the results from a particular experiment to the researcher who conducted it. The report states that on one specific part of the experiment, a statistical test result yielded a p-value of 0.21. Based on this p-value, what should the researcher conclude?
The test was not statistically significant because 2 × 0.21 = 0.42, which is less than 0.5.
The test was statistically significant because a p-value of 0.21 is greater than a significance level of 0.05.
The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time.
The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time.
The test was statistically significant because p = 1 − 0.21 = 0.79, which is greater than a significance level of 0.05.
Answer:
The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time.
Step-by-step explanation:
This is the right answer,since this result is only observed 21% of the time, so in general it's not significant, so the first 2 are eliminated. The 2 x 0.21 doesn't matter since, the percent is 21% not 42%, so it doesn't even matter. The last question we eliminate is:"The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time" 79% of the time is a pretty good amount to say it's significant, but it only says 21% of the time.So, it leaves us with:The test was not statistically significant because if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time.
