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.

angle A and angle B are complementary angles. If measure angle A= (2x – 4)º and measure angle
B = (5x + 17)°, then find the measure of angle A.
Answer:
Angle A = 18°
Step-by-step explanation:
since the angles are complementary, they add up to 90°
(2x-4) + (5x+17) = 90
add like terms
7x-4+17=90
simplify left side
7x+13=90
subtract 13 from both sides
7x=77
divide both sides by 7
x=11
plug in x to find the measure of angle A
2(11) - 4
multiply 2*11 first
22-4

The lengths of the legs of a right triangle are 6 and 10. What is the length of the hypotenuse to the nearest tenth?
Answer:
h ≈ 11.7
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse (h) is equal to the sum of the squares on the other 2 sides, that is
h² = 6² + 10² = 36 + 100 = 136 ( take the square root of both sides )
h = [tex]\sqrt{136}[/tex] ≈ 11.7 ( to the nearest tenth )
Length of the hypotenuse is equal to [tex]\boldsymbol{11.7}[/tex]
Right triangleA right triangle, also known as a right-angled triangle, or more formally an orthogonal triangle, was originally known as a rectangle triangle, is a triangle with one right angle and two perpendicular sides.
Lengths of the legs of a right triangle are equal to [tex]\boldsymbol{6,10}[/tex]
Square of the length of the hypotenuse is equal to sum of squares lengths of the legs.
So,
Length of the hypotenuse [tex]=\sqrt{6^2+10^2}[/tex]
[tex]=\sqrt{36+100}\\ =\boldsymbol{11.7}[/tex]

Answer:
170
Step-by-step explanation:
Let the number of cell phones be x
2 : 3 = 68: x
Product of extremes = product of means
2 * x = 68 * 3
x = [tex]\frac{68*3}{2}[/tex]
= 34 * 3
x = 102
Number of phones = 102 + 68 = 170
Complementary angles are two angles that have measures with a sum of 90°. Angles P and Q are complementary and the measure of angle P is 6° more than twice the measure of angle Q.
Write a system of equations and use substitution to find the measures of angles P and Q.
Input Field 1 of 1
Answer:
P = 62° Q = 28°
Step-by-step explanation:
Let x = measure of angle Q
then y = measure of angle P
Now x + y = 90 and 2x + 6 = y
Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.
3x + 6 = 90
3x = 84
x = 28
y = 2(28) + 6 = 56 + 6 = 62
Check: 28 + 62 = 90

a car traveled 120 miles at a certain average rate. by increasing its average rate by 10 mph, it traveled 160 miles in the same time it traveled 120 what is the average rate for the first trip
Answer: trip one= 30 mph
Step-by-step explanation:
R*t= distance
First trip= r1*t1= 120 miles
Second trip= (R1+10)*t1= 160 miles
Solve for t1
T1=4
Use Equation from first trip
R1* 4= 120
R1= 30 mph
What is the y-intercept of the function f(x)
f(x) = -_x + ?
Note: Your function is not clear.
So, I am assuming a sample function such as
f(x) = -2x + 3
So, I would solve the question based on the assuming function. The reason is that the procedure will remain the same and your concept will be likely cleared anyways.
Answer:
Please check the explanation.
Step-by-step explanation:
Assuming the function
f(x) = -2x + 3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
now substituting x = 0 in the function
y = -2x + 3
y = -2(0) + 3
y = 0 + 3
y = 3
Therefore, the point (0, 3) represents the y-intercept of the function.
The graph of the function y = -2x + 3 is also attched below.
From the graph, it is clear that
at x = 0, y = 3
Thus, point (0, 3) represents the y-intercept of the function.
