Last year, Chang opened an investment account with S8500. At the end of the year, the amount in the account had decreased by 6.8% How much is this
decrease in dollars? How much money was in his account at the end of last year?
Decrease in amount:
Year-end amount:
Answer:
Decrease in amount= $578
Year-end amount= $7,922
Step-by-step explanation:
0.068=x/8500
Isolate x to multiply 0.068 by 8500= 578 which is the decrease in dollars.
so, 8500-578= $7,922 is how much money was in his account at the end of last year.
Decrease in amount: $578
Year-end amount: $7922
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Last year, Chang opened an investment account with, $8500.
At the end of the year, the amount in the account had decreased by 6.8%
To find the decrease in amount;
6.8% of $8500
= 8500 x 6.8 / 100
= 57800/100
= $578
At the end of the last year, amount,
$8500 - $578
= $7922
Therefore, the required amounts are $578 and $7922.

Is the statement below always something or never true give at least two examples to support your reasoning the LCM of two numbers is the product of two numbers discuss your conditions with a partner
Answer:
Sometimes, it is true
Step-by-step explanation:
The L. C. M of two numbers could be the product of the two Given numbers. This happens sometimes but not always. For instance, the Lowest Common. Multiple of 4 and 5 is 20
4 : 4, 8, 12, 16, 20, 24, 28, 32
5 : 5, 10, 15, 20, 25,...
L. C. M = 20 ; 4 * 5 = 20
However, L. C. M of 4 and 8
4 : 4, 8, 12, 16, 20, 24, 28, 32
8 : 8, 16, 24, 32, 40
L.C.M = 8 ; 4 * 8 = 32
HENCE, L. C. M could be the product of the 2 numbers sometimes and it may not in other scenarios.
3(x + 2) = 8 + 3x – 2
Answer:
Step-by-step explanation:
3x + 6 = 8 + 3x - 2
3x + 6 = 3x + 6
Bringing like terms on one side
3x - 3x = 6 - 6
0 = 0
Answer:
no solution
Step-by-step explanation:
3(x + 2) = 8 + 3x - 2 Explanation of steps
3 times x and 3 times 2 then 8-2=6
3x + 6 = 6 + 3x
3x - 3x = 6

The length of a rectangle is 15 less than three times the width. The perimeter of the rectangle is 178 centimeters. What is the length of the rectangle?
Answer:
40.5in
Step-by-step explanation:
Given data
Let the width be x
L= 3x-15
Perimeter= 178cm
We know that
P=2L+2W
substitute
178= 2(3x-15)+2x
open bracket
178=6x-30+2x
collect like terms
178=8x-30
178-30= 8x
148= 8x
divide both sides by 8
x= 148/8
x=18.5 in
but L= 3x-15
L= 3*18.5-15
L=55.5-15
L=40.5 in
Hence the length is 40.5in

1)Find the scale factor of Figure A to Figure B.
2) Solve for the missing length of x.
Answer:
x = 12
Step-by-step explanation:
Here, we want to get the value of x
Looking at the angles of the shapes, we can see that the two figures are similar
When two figures are similar, the ratio of their corresponding sides are equal
Thus, mathematically, we have it that;
MN/PN = HJ/KJ
9/x = 6/8
9 * 8 = 6 * x
6x = 72
x = 72/6
x = 12
Answer:
1) The scale factor of Figure A to Figure B is 5/9
2) x = 12
3) y = 10
Step-by-step explanation:
1) The scale factor of figure 'A' to Figure 'B', is given by the ratio of the side of figure 'A' to the corresponding side of Figure 'B'
The corresponding longest sides of Figures 'A' and 'B' are, 36 and 20 respectively
The corresponding shortest sides of Figures 'A' and 'B' are, 25.2 and 14 respectively
Therefore, the scale factor of Figure A to Figure B = 20/36 = 14/25.2 = 5/9
Therefore, in order to get the dimension of Figure 'B' we multiply the dimension of Figure 'A' by 5/9
The scale factor of Figure A to Figure B = 5/9
2) Given that the quadrilaterals LMNP, and GHJK are similar
The scale factor of Figure LMNP to Figure GHJK = 4/6 = 2/3
Therefore, given that the corresponding side to segment NP of length 'x' in figure GHJK is segment JK
Therefore, the scale factor of NP to JK = 2/3
Length of JK = 2/3× Length of NP
Length of JK = 8
Length of NP = x
∴ 8 = 2/3 × x
x = 3 × 8/2 = 12
x = 12
3) Similarly, from the scale factor of Figure LMNP to Figure = 2/3, we have;
Length of GK = 2/3× Length of LP
Length of GK = y
Length of LP = 15
∴ y = (2/3) × 15 = 10
y = 10

Answer: a=60°, b=25°, c=95°,d=60°, e=25°, f=95°, g=60, h=35°
Step-by-step explanation:
a=60°, Because the angle opposite to it is 60°
b=25°, Because if you take 180°-155°, you get 25°
c=95°, Because if you add angles a and b, you get 85°, then you do 180°-85°=95°
d=60°, Because the angle opposite to it does
f=95°, Because angle c, which is opposite to it equals 95°
g=60°, Because if you add angles e and f, you get 85°, then you take 180°-85=95°
h=35°, Because if you add angles c and d, which is 155°, you take 180°-155=35°

Answer:
The first one is 14 the second is 30 and the last one is 10
Answer:
1. d = 14
2. d = 30
3. d = 10
Step-by-step explanation:For the first one, divide both sides by 6.Ex. Divide 6d by 6 and you get d. Divide 84 by 6 and you get 14. d = 14
For the second one, divide both sides by 15.For the third one, divide both sides by 11.Which equations are true for the values of x, y, and z in the figure? Select all that apply.

Find the sales tax. Then find the total cost of the item. Sales Tax Selling Price Rate of Sales Tax Sales Tax $60.00 8% ? The sales tax is $ The total cost is $
Answer: Sales tax is $4.80 and the total cost is $64.80
Step-by-step explanation: Take the difference in the total before and after tax and divide by the price before tax.
To get $4.80, find the sales tax of $60.00 of 8%
We can use this formula: (selling price x sales tax rate)
The sales tax is: $4.80
To find the total cost, add 60.00 by the sales tax. ($4.80)
60.00 + 4.80 = $64.80
Therefore, these are your answers: $4.80 and $64.80
Answer:
4.80 sales tax, 64.80 total costs
Step-by-step explanation:
60 x.08=4.80 sales tax
60+4.80=64.80 total costs
