Answer:
A. △GHD ≅ △EDH by SAS
Step-by-step explanation:
This is right on edge. 2020
In triangles GHD and EDH angle GHD and angle EDH is congruent, side GH is congruent to the side ED, and side HD is congruent to side HD. So, from side angle side postulate triangle GHD and triangle EDH are congruent.
Given :
∠GHD and ∠EDH are rightGH ≅ ED Triangles G H D and E D H overlap and intersect at point F.The triangles share side H D. Sides G H and E D are congruent. angles G H D and E D H are right angles.In the Side Angle Side postulate, the two sides and the included angle of one triangle are congruent to the two sides and the included angle of another triangle.
Given that in triangles GHD and EDH angle GHD and angle EDH is congruent, side GH is congruent to the side ED, and side HD is congruent to side HD.
So, from side angle side postulate triangle GHD and triangle EDH are congruent. Therefore, the correct option is A).

Solve the system of equations using substitution.
4x - y = 7
3y – 12x = -21
(3,5)
(6, 17)
no solution
infinite solutions
Answer:
Infinite amount of solutions
Step-by-step explanation:
Step 1: Write systems of equations
4x - y = 7
3y - 12x = -21
Step 2: Rewrite
-y = 7 - 4x
y = 4x - 7
Step 3: Solve for x
Substitute in y into second equation: 3(4x - 7) - 12x = -21Distribute 3: 12x - 21 - 12x = -21Combine like terms: -21 = -21Here we see that we would have infinite amount of solutions.

what negative angle is equivalent to a 75 angle
Answer: it’s actually -285
Step-by-step explanation: took test
The negative angle equivalent to a 75 angle is -285 angle.
We are given a 75 angle and we need to find a negative angle that is equivalent to the 75 angle.
What is a negative angle?A negative angle is defined as an angle generated in a clockwise direction from its given base.
We have a 75 angle which is in an anti-clockwise direction from the base AB as shown in the figure.
Now we will draw an angle in a clockwise direction from the base AB such that the angle reaches angle 75 which means it is equivalent to angle 75
We have,
Adding the angle from base AB till angle 75.
90° + 90° + 90° + 15° = 285°
Since the angle is measured in a clockwise direction we have,
285° = - 285°
The negative angle equivalent to a 75 angle is -285 angle.

You deposit $900 in a savings account that earns a simple interest rate of 4.5% per year. You calculate you will earn $1215 in interest over 3 years. Is your answer reasonable?
A. Yes; the interest will be much less than the total in the account
B. No; the interest will be much less than the total in the account.
C. No; the interest will be more than the total in the account.
D. Yes; the interest will be more than the total in the account.
Answer:
a..
Step-by-step explanation:
yes the interest will be much less than total than the account
The answer is not reasonable because the interest will be much less than the total in the account.
In order to determine if the answer is reasonable, we have to determine the simple interest that would be earned and the total amount in the account.
Simple interest = amount deposited x time x interest rate
$900 x 0.045 x 3 = $121.50
The total amount in the account in three years = amount deposited + interest earned
$900 + $121.50 = $1021.50.

1. Juliet O'Hara works for a weekly paycheck. Last week she worked 5 days for a total of 39 hours. Her regular rate of pay is $10.95 an hour. In addition to federal income tax, state income tax, Medicare, and social security, Juliet also has insurance of $20 a week withheld and puts 4% of her gross pay into a retirement account. Compute her gross pay, deductions, and net pay. SHOW YOUR WORK!
Step-by-step explanation:
given data:
hours worked weekly = 39
pay/her = $10.95
insurance withheld weekly = $20
percentage put into Retirement = 4%
Solution:
Gross pay
= hrs worked weekly x pay/hr
= 39 x $10.95
= $427.05.
Deductions
insurance deduction
= $427.05 – $20
= $407.05
Amount put into retirement account
= 4% of $427.05
= 4/100 x $427.05
= $17.082
NET PAY
= $427.05 – $20 –$17.082
= $389.97
At the season finale, you present the winner of Canadian Superstar with a recording-and-tour contract. The contract states that the winner will be paid $5000 per month while on tour plus $2 per CD sold. Rn Did You Know? A) Vrite an equation that relates total earnings in terms of the number of months, m, on tour and the number, n, of CDs sold. In March 2003, Dark Side of the Moon, by Pink Floyd, achieved double diamond status in Canada for selling over 2000000 units. B) How much will the winner earn after the first month if 500 CDs are sold? C) Suppose after the third month on tour the new recording artist has earned a total of $74 000. How many GDs were sold? D) In Canada, a record album or CD achieves gold status once it seLls 50 000 units. How much will the artist make if the CD goes gold after 6 months of touring?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Winner is paid :
Monthly pay while on tour = $5000
Pay per CD sold =. $2
A) Equation which relates total earning in terms of number of months 'm' while on tour and the number 'n' of CD's sold.
(Monthly pay * number of months) + (pay per CD * number of CD's)
Earning = 5000m + 2n
B) How much will the winner earn after the first month if 500 CDs are sold?
m = 1, n = 500
5000(1) + 2(500) = $6000
C) Suppose after the third month on tour the new recording artist has earned a total of $74 000. How many GDs were sold?
m = 3
74000 = 5000(3) + 2n
74000 = 15000 + 2n
74000 - 15000 = 2n
59000 = 2n
n = 59000 / 2
n = 29500 CD's
D) In Canada, a record album or CD achieves gold status once it seLls 50 000 units. How much will the artist make if the CD goes gold after 6 months of touring?
n = Gold = 50000 ; m = 6
5000(6) + 2(50000)
30000 + 100000 = 130,000

During a sale at the mal, all items were marked down 40% off of the original price. Lily purchased a purse that was originall $220.00. What is the price of the purse after the discount?
Answer:
$132
Step-by-step explanation:
40% off means it is actually 60% of the regular price.
Thus, you will multiply the original (220) by .6 (this means 60 percent)
and you will get 220*.6=132
Answer:
132
Step-by-step explanation:
First, find 40% of 220, which is 88 (220 * 0.4). Since everything was marked down, 40% was taken off the original price. So, 220 - 88 = 132

67.5 Divided by 2.25 show work please:(!!
Answer:
The right answer for your question is 30 because if you divide 67.5 by 2.25 then,the quotient would be 30.
Hope it helps you.
The required solution will be 30 which is determined by 67.5 divided by 2.25.
What is the division operation?The basic arithmetic operations are division, multiplication (the opposite of division), addition, and subtraction. Arithmetic operations are methods for combining integers to generate new numbers. The division is defined as the number of times a given number is divided by another number.
67.5 Divided by 2.25
67.5 ÷ 2.25
Convert the dividend and divisor to integers by multiplying each by 100, making them 6750 and 225 respectively.
⇒ 6750 / 225
Apply the division operation, and we get
⇒ 30
Thus, the required solution will be 30 which is determined by 67.5 divided by 2.25.

Step-by-step explanation:
The first one is already solved for y, so when you plug 9 into the equation in the x spot since 9 is the x-coordinate of the point, you get -2, which is correct because it is the corresponding y-value.
The second one is a mess when trying to solve and it clearly doesn't yield the right answer.
For the last one, when you solve for y and then plug in 9 for x, you get -2, the y-value making it correct.

The temperature at 8 p.m. was 6 degrees. at 2 p.m. the temperature decreased 13 degrees. What was the temperature at 2 a.m.?
Step-by-step explanation:
Given parameters:
Temperature at 8pm = 6°C
Temperature at 2am = decreased by 13°C
Unknown:
Temperature at 2am
Solution:
Since this is a temperature decrease problem, the temperature at 2am should be lesser.
Temperature at 2am = Temperature at 8pm - Temperature decrease
= 6°C - 13°C
= -7°C

An electrician charges an hourly rate of $50, but also charges a fixed fee for making house calls regardless of time spend on the job. One day, the electrician earned a total of $250 for a 2 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.
