Answer:
80
Step-by-step explanation:
We let x be Ann's savings.
Betty saves 3 times as much as Ann.
This implies that Betty's savings in terms of x

Charles save 390 less than Ann.
This implies Charles savings

Betty saves 1330 more than Charles.
This implies that when we deduct Charles savings from Betty's we have to get 1330.
Mathematical equation for the problem:

Expand :


Subtract 390 from both sides.


Divide through by 2


Hence Charles saving is

Answer:
Katie's account balance in 10 years will be $3,769,875
Step-by-step explanation:
you multiply the amount of money you invest by the percentage, and the amount of years.
EX: $33,750 × 11.17% × 10= $3,769,875
In geometry, similar figures are those whose ratios of the corresponding sides are equal and the corresponding angles are congruent. In relation to the volume, we determine first the cube roots of the given and find the ratio as shown below.
s1 / s2 = cube root of (512/343)
= 8/7
The square of this ratio is the ratio of the areas of the figure. If we let x be the area of the smaller figure then,
(8/7)^2 = 192 mm²/ x
The value of x from the equation is 147 mm².
The area therefore of the smaller figure is 147 mm².
Answer:
A: 6x⁸y⁵
B: 4x⁵z⁸
C: 48a¹²b⁵
D: 6s⁹t³
Step-by-step explanation:
When you multiply 2 exponents together, you add them. When you power an exponent, you multiply the 2 exponents together,
3x²2y⁴(2x⁶y)
6x⁸y⁵
xz³(4x⁴z⁵)
4x⁵z⁸
(4a³)²(3a⁶b⁵)
16a⁶(3a⁶b⁵)
48a¹²b⁵
6s⁵t(s⁴t²)
6s⁹t³
