You borrow $10,000 to buy a car. The simple interest rate is 3%. You pay the loan off after 6 years. What is the total amount you paid for the loan?
Answer:
The total amount of money needed to pay off the car after 6 years would be $11,800.
Step-by-step explanation:
Write down the facts:
The car costs $10,000The interest rate is 3%And you finished paying the loan off after 6 yearsInterest = $10,000 * 0.03 * 6
This being $10,000, 3% interest rate and over 6 years.
Interest= $1800
This amount we found is the additional amount (interest) you have to pay with the $10,000. Now, to find the total amound we add the interest and $10,000.
Total amount = 10,000 + $1800
Total amount = $11,800
Therefore the total amount paid over 6 years (including the 3% interest rate) would be $11,800. I hope this helped!!!
$11800 is the answer

1. A 32-ounce tub of yoghurt contains 5 servings. Write and solve an equation to find how many ounces of yoghurt is in 1 serving.
1 serving has 6.4 ounces of yogurt.
To find how many ounces there are in 1 serving, we need to divide the ounces by the number of servings. So 32/5 which equals 6.4.

Solve for x.
Answer: x = 4
Step-by-step explanation:
The little box in this angle represents 90 degrees, so we can set up an equation and solve.
Given:
12x + 5 = 90 - 37
Subtract:
12x + 5 = 53
Subtract 5 from both sides of the equation:
12x = 48
Divide both sides of the equation by 12:
x = 4

Answer:
4x^2 - 25
Step-by-step explanation:
b^2, such that:
(2x+5)(2x-5) = (2x)^2 - (5)^2Applying the exponential rule, you receive:(2x)^2 - (5)^2 = 2^2 * x^2 - 5^2
And simplifying, 2^2 * x^2 - 5^2 you receive:
4x^2 - 25
As simple as that!

In football, a player scores 6 points for a touchdown and 3 points for a field goal. Sujiths team scored 2 touchdowns in this week and last week they scored 1 touchdown and 1 field goal. How many points did Sujiths team score in both weeks?
Answer: 21 points
Step-by-step explanation:
Answer:
In both weeks Sujiths team will score 21 points
Step-by-step explanation:
the ratio for a touchdown is 6 points for 1, and the ration for a field goal is 3 points for 1. So in the if hes team scored 2 touchdowns in this week and last week they scored 1 touchdown and 1 field goal. You would do 6 points for 1 twice so that would be 12 then another 6 point so that would be 18 (for touchdowns). Then 3 points once so that would be 3 (for field goals). Finally add the two together to get the final answer of 21.

What is the simplified form of (3x3 – 4x2 + 6x) – (5x3 + 2x2 – 3x) in standard form?
A. –3x3 – 2x2 + 3x
B. –2x3 – 6x2 – 3x
C. –2x3 – 6x2 + 9x
D. 8x3 – 6x2 – 9x
Answer: The given expression is:
(3x^3 - 4x^2 + 6x) - (5x^3 + 2x^2 - 3x)
On simplifying, we get:
3x^3 - 4x^2 + 6x - 5x^3 - 2x^2 + 3x
Combining like terms, we get:
(-5 + 3)x^3 + (-4 - 2)x^2 + (6 + 3)x
Simplifying further, we get:
-2x^3 - 6x^2 + 9x
Therefore, the simplified form of the expression in standard form is:
C. –2x^3 – 6x^2 + 9x

Answer:
150
Step-by-step explanation:
Total birds= 500
No.of geese= 30*500/100
=150
Let no.of ducks =x
no.of chickens= x+50
No. of ducks+ chickens= 500-150= 350
x+x+50=350
2x=300
x=150
Thus he has 150 ducks.
30% of 500 = 150
There are 150 geese.
chickens > ducks.
500 - 150 = 350
"..50 more chickens than ducks.."
350 - 50 = 300
300 ÷ 2 = 150
150 + 50 = 200
there are 200 chickens
There are 150 ducks

Answer:
y = -3
Step-by-step explanation:
Isolate y
5y + 4 = 2y - 5
subtract y from both equations
3y + 4 = -5
Add 5 to both sides
3y +9 = 0
subtract 9 from both sides
3y = -9
divide both sides by 3
y = -3

What is the volume of this figure?
78% of x is 3.822, y% of 8 is 0.248
To solve for x and y, we can use the following equations based on the information given:
1.) 78% of x is 3.822:
0.78x = 3.822
x = 3.822/0.78
x ≈ 4.900
Therefore, 78% of x is approximately 3.822 when x is approximately 4.900.
2.) y% of 8 is 0.248:
(y/100)8 = 0.248
y/100 = 0.248/8
y/100 = 0.031
y = 0.031100
y = 3.1
Therefore, y% of 8 is 0.248 when y is equal to 3.1.

which algebraic rule describes the translation of DEF to D'E'F'
Answer:
The answer is C. (x,y) ---> (x-4,y-7)
Step-by-step explanation:
The points for DEF are:
D = (-1,5)
E = (3,3)
F = (-1,3)
If you go through these points and subtract 4 from the x values and 7 from the y values you'll get:
D' = (-5,-2)
E = (-1,-4)
F = (-5,-4)
Which match the values of D'E'F'.
Hope this helps :)
