Mariah will deposit $1,530 in an account that earns 6% simple interest every year. Her
sister Isabel will deposit $1,500 in an account that earns 8% interest compounded
annually. The deposits will be made on the same day, and no additional money will be
deposited or withdrawn from the accounts. Which statement about the balances of
Mariah's account and Isabel account at the end of the 3 years is true?
Answer:
After 3 years Mariah will have $1,805.40 while her sister Isabel will have $1,889.56.
Step-by-step explanation:
Since Mariah will deposit $ 1,530 in an account that earns 6% simple interest every year, while her sister Isabel will deposit $ 1,500 in an account that earns 8% interest compounded annually, and the deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts, to determine the balances of Mariah's account and Isabel account at the end of the 3 years the following calculations must be performed:
Mariah:
1,530 + ((1,530 x 0.06) x 3) = X
1,530 + (91.8 x 3) = X
1,530 + 275.4 = X
1,805.4 = X
Isabel:
1,500 x (1 + 0.08 / 1) ^ 3x1 = X
1,500 x 1.08 ^ 3 = X
1,500 x 1,259712 = X
1,889.568 = X
Therefore, after 3 years Mariah will have $ 1,805.40 while her sister Isabel will have $ 1,889.56.

how to solve 12x-y=37 and -5x-y=-14 using elimination method and please show work
Answer:
x = 3, y= -1
Step-by-step explanation:
12x-y=37
-5x-y=-14
12x-y=37
-1(-5x-y)=-1(-14)
12x-y+5x+y=37+14
17x = 51
(17x)/17 = 51/17
x = 3
12(3)-y=37
36-y=37
-y = 1
y = -1

What is 75% of 44 cookies
Answer: 33 cookies.
Step-by-step explanation: To find the 75% of 44 cookies, use these steps:
Step 1: Our output value is 44.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 44 = 100%.
Step 4: Similarly, x = 75%.
Step 5: This results in a pair of simple equations:
44 = 100%(1)x = 75%(2)Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right-hand side) of both equations have the same unit (%); we have:
[tex]\frac{44}{x} \\[/tex] = [tex]\frac{100 percent}{75 percent}[/tex]Step 7: Again, the reciprocal of both sides gives:
[tex]\frac{x}{44}[/tex] = [tex]\frac{75}{100}[/tex]x = 33Therefore, 75% of 44 is 33. Thus, it is 33 cookies.

the x next to 13 is not multiply
8 1/6 * 2^2 = 32 1/2
Work out the exact value of x.
Answer:
For short Go all the down
Conversion a mixed number 8 1/4
to a improper fraction: 8 1/4 = 8 1/4
= 8 · 4 + 1/4
= 32 + 1/4
= 33/4
To find new numerator:
a) Multiply the whole number 8 by the denominator 4. Whole number 8 equally 8 * 4/4
= 32/4
b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33
c) Write a previous answer (new numerator 33) over the denominator 4.
Eight and one quarter is thirty-three quarters
Conversion a mixed number 3 2/5
to a improper fraction: 3 2/5 = 3 2/5
= 3 · 5 + 2/5
= 15 + 2/5
= 17/5
To find new numerator:
a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/5 = 15/5
b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17
c) Write a previous answer (new numerator 17) over the denominator 5.
Three and two fifths is seventeen fifths
Subtract: 33/4
- 17/5
= 33 · 5/4 · 5
- 17 · 4/5 · 4
= 165/20- 68/20
= 165 - 68/20
= 97/20
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 5) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 5 = 20. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - thirty-three quarters minus seventeen fifths = ninety-seven twentieths.
Conversion a mixed number 2 1/3
to a improper fraction: 2 1/3 = 2 1/3
= 2 · 3 + 1/3
= 6 + 1/3
= 7/3
To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3
= 6/3
b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 3.
Two and one third is seven thirds
Subtract: 7/3 - 1/4
= 7 · 4/3 · 4 - 1 · 3/4 · 3
= 28/12- 3/12
= 28 - 3/12
= 25/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven thirds minus one quarter = twenty-five twelfths.
Subtract: the result of step No. 3 - the result of step No. 5 = 97/
20 - 25/12
= 97 · 3/20 · 3 - 25 · 5/12 · 5
= 291/60 - 125/60
= 291 - 125/60
= 166/60
= 2 · 83/2 · 30
= 83/30
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(20, 12) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 20 × 12 = 240. In the next intermediate step, , cancel by a common factor of 2 gives 83/30
In words - ninety-seven twentieths minus twenty-five twelfths = eighty-three thirtieths.
Step-by-step explanation:
83/30 is the awnser

What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " sign here denotes the resemblance of triangles.
In Triangle ABC and YZX
a) So, the pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fractions with your side pairs is
YZ / AB = 30 / 40 = 3/4
XY / AC = 37.5 / 50 = 3/4
XZ / BC = 45/ 60 = 3/4.
c) As, the ratio of sides are proportion.

Answer:
B and D.
Step-by-step explanation:
If we divide the numerator by the denominator (i.e. 2 divided by 5 which is 0.4 or 40%) we get decimal points that we can then convert to percentages.
A. 2 divided by 5 is 0.4 or 40%.
B. 3 divided by 5 is 0.6 or 60%.
C. 1 divided by 3 is approx. 0.33 or approx. 33.33%.

What is the slope and y-intercept of the line?
Answer:
Slope = 3
Y-intercept = -2
Step-by-step explanation:
Points on the line: (0, -2) and (1,1)
Slope:
m=(y2-y1)/(x2-x1)
m=(1+2)/(1-0)
m= 3/1
m = 3
Slope-intercept:
y - y1 = m(x - x1)
y + 2 = 3(x - 0)
y + 2 = 3x
y = 3x - 2
y = mx + b, where
m = slope
b = y-intercept

A mixture contains 3.7 × 10–6 grams of carbon powder and 0.000092 grams of ammonium carbonate.
What is the difference in the amounts of carbon powder and ammonium carbonate?
Answer:
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
Step-by-step explanation:
According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:
[tex]\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g[/tex]
[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

What is the volume of a hemisphere with a diameter of 8.6 ft, rounded to the nearest tenth of a cubic foot?
Answer:
166.52 cubic feet.
Step-by-step explanation:
We can Know the volume of a by using the expression below
V =[ (4/3)πr^3] .............eqn(1)
Given Diameter= 8.6 ft
radius= Diameter/ 2 = (8.6 ft)/2 = 4.3 ft
Eqn(1) gives the formula for volume of a WHOLE sphere, but what we need is
HALF of whole sphere, then we have
V =[ (4/3)πr^3] / 2
Then eqn(1) becomes [ (2/3)πr^3]
Volume of hemisphere
= [ (2/3)πr^3].....eqn(2)
If we substitute into eqn(2) we have
Radius= 4.3 ft
V(hemisphere) = (2/3)π(4.3)^3
= 166.52 cubic feet.
Hence, the volume of a hemisphere is
166.52 cubic feet.
