If the question is how much she would have in each account the value would be that two would have $9,333 and one would have to be $9,334
Step-by-step explanation:
write the ratio to 10 ounces to 4 pounds
1 pound = 16 ounces
you should make both with the same unit measurement. Let's convert them to ounces.
4 pounds= 4x16 ounces=64 ounces
ratio 10 ounces to 4 pounds= 10 ounces : 64 ounces
= 5 ounces : 32 ounces= 5 : 32
Answer:
5 : 32Step-by-step explanation:
1 pound = 16 ouncestherefore, 4 pounds = 64 ounces= 10 ounces : 64 ounces = 5 : 32Here is ur answer !!!plzz like share and comment guys!!!!!!! and don't forget to vote

What’s this I need help with math...
Answer:
3^12 = 531441
Step-by-step explanation:
For this problem, it's important to understand what is meant by the exponents. Notice, there are two sets of separators, a parentheses and a bracket. When you have powers to powers you multiply, hence 2 * 3 * 2 is 12. The given expression can also be broken down like this:
[ ( 3^2 ) ^ 3 ] ^ 2
= [ 3^2 * 3^2 * 3^2 ] ^ 2
= 3^2 * 3^2 * 3^2 * 3^2 * 3^2 * 3^2
And we can apply the rule, when you are multiply powers of like bases you add the exponents. Hence:
3 ^ (2 + 2 + 2 + 2 + 2 + 2)
= 3^12
Either way of power manipulation, you end with the same result of 3^12. Hope this helps.

If angle W and angle V are supplementary angels and measure at V is 49 degrees what does measure of angle W equal?
Answer:
131
Step-by-step explanation:
supplementary angles are any two angles whode sum is 180. If v= 49 then 131 would be W. 131+49= 180
Please help me! Find the sale price
Answer:
sale price is $104
Step-by-step explanation:
Given the equation in the problem S=P-0.20P:S = P - 0.20PS = (130.00) - (0.20 · 130.00)S = 130-26S = $104Answer:
$104.00
Step-by-step explanation:
So we know that in the equation:
S = P - 0.20P
P is the original price and S is the sale price, which is also the original price reduced by 20%.
We are also given that the original price of a digital media player is $130.00.
We are asked to find the sales price of that digital media player. To do this, we can plug in $130.00 for P in the given equation, since it is the original price of the digital media player, and solve for S, the sales price:
S = 130 - (0.20)(130)
S = 130 - 26
S = 104
So now we found the sales price of the digital media player, which is $104.00.
I hope you find my answer helpful.
How do you do question #5?
Step-by-step explanation:
If two variables x and y are independent, then:
P(x and y) = P(x) P(y)
Or, in terms of conditional probability:
P(x given y) = P(x)
From part 3, 27.3% of the students are sophomores, 57.8% are juniors, and 14.8% are seniors.
From part 4, 31.6% of procrastinators are sophomores, 53.6% are juniors, and 14.8% are seniors.
Since the percent of procrastinators that are sophmores is not the same as the percent of students that are sophmores, the variables are not independent, which means there is a relationship between academic level and whether students procrastinate.
Need help on this question please
===========================================================
Explanation:
Check out the diagram below. I've added in the label (4x+13) degrees to the angle adjacent to the (9x-2) degree angle. This is valid due to corresponding angles being congruent when we have parallel lines like this.
The two angles form a 180 degree straight angle
(4x+13) + (9x-2) = 180
4x+13 + 9x-2 = 180
(4x+9x) + (13-2) = 180
13x + 11 = 180
13x+11-11 = 180-11 .... subtracting 11 from both sides
13x = 169
13x/13 = 169/13 .... dividing both sides by 13
x = 13
We can verify this by noticing that
4x+13 = 4*13+13 = 65
9x-2 = 9*13-2 = 115
So, (4x+13)+(9x-2) = (65)+(115) = 180, showing the two angles are supplementary.
-----------------
The angles (9x-2) and (6y-1) are also a linear pair. They are adjacent and supplementary
Let's use x = 13 to find the value of y
(9x-2) + (6y-1) = 180
9x-2+6y-1 = 180
9x+6y-3 = 180
9*13+6y-3 = 180 .... plug in x = 13
117+6y-3 = 180
6y+114 = 180
6y+114-114 = 180-114 .... subtract 114 from both sides
6y = 66
6y/6 = 66/6 ...... divide both sides by 6
y = 11
To help confirm,
6y-1 = 6*11-1 = 65
which adds onto the (9x-2) = 115 degree angle to get 180.
-----------
Side note: as an alternative, you can solve 4x+13 = 6y-1 to get the same y value. This is because alternate exterior angles are congruent when we have parallel lines like this.
Given f(x)=3x-1 find f(-1)
Answer:
f( - 1) = - 4Step-by-step explanation:
f(x) = 3x - 1
To find f(-1) substitute the value of x that's
- 1 into f(x). That's for every x in f(x) replace it with - 1 and solve
That's
f( - 1) = 3(-1) - 1
= - 3 - 1
We have the final answer as
f(-1) = - 4Hope this helps you

a suit is being sold at a 20 % off (discount). The sale price is $ 270. What was the original price ?
Answer:
The original price is 337.50
Step-by-step explanation:
If we get 20% off, we still have to pay 100-20 =80%
Let x be the original price
x *80% = 270
.80x = 270
Divide each side by .80
.80x/.80 = 270/.80
x =337.50
The original price is 337.50
Answer:
the original price was $324.
Step-by-step explanation:
since 20% of $270 is $54, you add the $54 and get $324.

A clown uses canisters of helium to make balloons. The graph shows the number of canisters used and the number of balloons created. What does the point (0,0) represent? A It shows the number of balloons created using 1 canister of helium. B It shows that when 0 canisters of helium are used, 0 balloons are created. C It shows that when 0 canisters of helium are used, 5 balloons are created. D It shows the number of canisters needed to create 10 balloons.
Answer:
B It shows that when 0 canisters of helium are used, 0 balloons are created
Step-by-step explanation:
from the graph, we can see that point (0,0) means that when the number of canisters of helium used is 0, then the number of balloons created is also 0
the closest answer to this observation is:
B It shows that when 0 canisters of helium are used, 0 balloons are created
