Answer:
m<A = 84
Step-by-step explanation:
1. Approach
Using the same-side interior angles are supplementary angles theorem, one can form an equation and solve for the unknown value (x). Then one can substitute the answer back into the expression that is given, and solve for the m<A.
2. Solve for (x)
When two parallel lines are intersected by a transversal line, then the same-side interior angles are supplementary, meaning that their angle measures add up to 180 degrees. Using this information, one can form an equation and solve for the value of (x).
m<A + m<B = 180
( 5x + 34 ) + ( 2x + 76 ) = 180
Simplify; combine like terms,
7x + 110 = 180
Inverse operations,
7x + 110 = 180
-110 -110
7x = 70
/7 /7
x = 10
3. Solve for m<A
Now that one has the value for the parameter (x), one can substitute this into the equation that has been given for (m<A), and solve for the value of (m<A).
m<A = 5x + 34
5(10) + 34
50 + 34

x-axis is the ground. Find the height of the highest point of the trajectory and the horizontal distance
the golf ball travels before hitting the ground.

Answer:
53.45 m254.55 mStep-by-step explanation:
Given function:
f(x) = 0.84x - 0.0033x²Rewrite in the standard form:
f(x) = - 0.0033x² + 0.84xThe maximum height is the vertex with x- coordinate -b/2a, which is:
x = -0.84/2(-0.0033) ≈ 127.27The highest point is:
f(127.27) = -0.0033(127.27)² + 0.84(127.27) ≈ 53.45 mThe horizontal distance the golf ball travels before hitting the ground:
f(x) = 0- 0.0033x² + 0.84x = 033x² - 8400x = 0x(33x - 8400) = 0x = 0- initial point33x = 8400 ⇒ x = 8400/33 ≈ 254.55 mCan somebody explain to me what algebra is

Suppose you have a total of $2.25 in dimes and
nickels. You have twice as many dimes, as nickels.
Which system of
equations could be used to
determine how many of each coin you have?
Answers
Answer:
Step-by-step explanation:
total money = $2.25 = 225 cents
types of denomination in coins or cents are dimes and nickels
dime = 10 cents , nickel = 5 cents
twice of dimes to nickels
let no of dimes = x and no of nickels = y
our equation
10x + 5y = 225
x = 2y
10(2y) + 5y = 225
20y +5y = 225
25 y = 225
y=9
x =2y 2x9 = 18
so the number of dimes = 18 and nickels = 9
cross verification:
10x18 + 5x9 = 180 +45 = 225

Percent of Discount
Sale Price
$60 20% __?
$140 65% __?
__? 40% $54.60
__? 10% $10.80
Answers
Answer:
1. $48
2.$49
3.$91
4.$12
Step-by-step explanation:
For 1 and 2
To find the sale price, you find out how much is the percentage of the original price. Example :
(20/100)/60 = $12
So $12 is the discount
thus sales price will be $60-$12=$48
Same thing for no.2, find the amount of the percentage and subtract it from the original price
For 3 and 4
To find the original price
1. Subtract the percentage from 100%
2. Multiply the sales price by 100
3. Divide the ans from no.2 by ans from no.1
Example :
100%-40%=60%
$54.60×100=5460
$5460÷60%= $91 (original price)
Same thing for no.4

The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be given as,
A = πr² square units
The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,
r = 34 / 2
d = 17 feet
The area of the circle is calculated as,
A = πr²
A = 3.14 x 17 x 17
A = 907.46 square feet
