Answer:
ac/5=a'c
Step-by-step explanation:
The quadrilateral ABCD is a parallelogram.
The value of a is?
Step-by-step explanation:
in a parallelogram, opposite angles are equal..
so C is 4a + 22. and B is 6a - 12.
sum of interior angles in a quadrilateral = 360
4a + 22. + 6a - 12. + 4a + 22. + 6a - 12 = 360
20a + 20 = 360
20a = 340
a = 17
sum of angles on a straight line = 180
B + x = 180
6 ( 17) - 12 + x = 180
102 + × = 180
× = 180 - 102
× = 78
I need to find x pls help
Dane sold a television for $35,000.
He was paid $1750 in commission for
his sale. At what rate was he paid
commission for the television?
Answer:
5%
Step-by-step explanation:
We can find the percentage of which he paid commission, by dividing the commision price by the television price:
1,750/35,000
This equates to 0.05.
In percentage form, this is 5%.
So the answer is that the commision fee is 5%.
Hope this helps!
How do you multiply 14.60 * 870
Answer:
12702
Step-by-step explanation:
Since there are 2 digits after the decimal in 14.60, add a decimal to the 870 and put two 0s after it (So it looks like this 870.00)
Then put the two numbers on top of each other, make sure to line up the decimals and multiply normally. When you're done, you should come out with the number 127020000. Since there is 2 digits behind the first number and 2 digits behind the second number, resulting in 4 digits, you're gonna count 4 numbers from the back of your answer and put a decimal there (so it is now 12702.0000) but you don't really need those 0s there so you can just remove them. (Answer 12702)
Hope this helped. If not, search up "Multiply a Whole Number by a Decimal | Math with Mr. J" it might explain better

Answer:
option B
Step-by-step explanation:
Given :
[tex]y = \frac{2}{3}x + 3\\\\y = \frac{5}{2}x + \frac{7}{2}\\\\[/tex]
Step 1 : simplify the equation :
[tex]3y = 2x + 9\\\\2y = 5x + 7\\[/tex]
Step 2: Arrange the terms :
[tex]2x - 3y = - 9\\\\5x -2 y = -7[/tex]
Step 3 : Solve for x and y :
2x - 3y = - 9 ------ ( 1 )
5x - 2y = - 7 --------- ( 2 )
_____________________
( 1 ) x 5 => 10x - 15y = - 45 ---------- (3 )
( 2) x 2 => 10x - 4y = - 14 ----------- (4 )
_______________________
( 3 ) - ( 4 ) => 0x - 11y = - 31
- 11 y = - 31
[tex]y = \frac{31}{11}[/tex]
Substitute y in ( 1 ) :
2x - 3y = - 9
[tex]2x - 3 (\frac{31}{11}) = - 9\\\\2x = -9 + 3(\frac{31}{11})\\\\2x = - 9 + \frac{93}{11}\\\\2x = \frac{-99 + 93}{11} \\\\2x = \frac{-6}{11} \\\\x = \frac{-6}{2 \times 11} = -\frac{3}{11}[/tex]
Therefore the solution to the sytem is [tex]( - \frac{3}{11} , \frac{31}{11})[/tex]
The solution of the system of equation is a point which lies
on the both the lines.
Option A : False , It says the solution lies above one of the given line.
But the solution of the system of equation always lies on
both the line.
Option B : True , says the solution is a point on the coordinate plane.
Option C : False, because if the solution is on the x-axis , then
the y coordinate in the solution would be zero.
But it is not zero.
Option D : False , the solution is the point where both the lines intersect.

a) what is the difference in temperatures between 7 am to 5 pm
b) which part of the day was the temperature rising the fastest a, b, c, d, or e?
Answers:
a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'=========================================================
Explanations:
a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.the radius of the cylinder is 6 m and the height is 10 m what's the volume?

Answer:
$1251.59
Step-by-step explanation:
tax percent = 6.7%
cost price of watch = $113
tax amount = tax percent of total price
=6.7 % * 1173
=6.7/100 *1173
=78.591
Now find total cost of a watch with tax
total cost = tax amount + original cost price
=$78.591 + $1173
=$1251.59

Help!! For this question I got 254.34 as my final answer but when I checked my answer it told me I was wrong?
Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)

Answer:
Perimeter= 20 cm
Area = 25 cm^2
Difference between 28cm^2 and 8cm^2= 20cm^2
Step-by-step explanation:
The formula to calculate the perimeter of a square is P= 4 * (the length of any side or "s").
Therefore:
P = 4 * 5cm
P = 20 cm
The formula for calculating the area of a square is A= (length of any side or "s")^2
So:
A= 5cm^2
A= 25cm^2
Remember the units in your answer!
The difference between indicates subtraction, and 28cm^2 and 8 cm^2 are like terms so:
28cm^2 - 8 cm^2 = 20 cm^2

What are Trigonometric Ratios?Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.
A right angled triangle is a triangle with measure of one of the angle as 90 degree.
The triangle XYW is a right triangle, with right angle at W.
The measure of angle X is f degrees and the measure of angle Y is d degrees.
The value of the trigonometric ratio sin f = 8/9
The measure of segment YW is 24 units,
The sin of an angle is the ratio of Perpendicular to the angle and the hypotenuse of the triangle.
sin f = YW / XY
8/9 = 24 / XY
XY = 24 * 9/8
XY = 27 °
The value of YX has been determined.

Assuming two hikers begin at a trail start, which scenarios must be true based on the table? Check all that apply. Melissa and Corey started on different trails. Melissa hiked up the trail for a longer period of time than Corey. Melissa and Corey crossed paths between 60 and 90 minutes. Corey began his descent before Melissa. As Melissa’s time increased from 0 to 60 minutes, her elevation decreased.
Answer:
1. Melissa and Corey started on different trails.
2. Melissa hiked up the trail for a longer period of time than Corey.
3. Melissa and Corey crossed paths between 60 and 90 minutes.
4. Corey began his descent before Melissa.
Step-by-step explanation:
A. Melissa and Corey started on different trails. - TRUE
Rationale: at the start, when t = 0, Melissa hiking trail elevation was 8,342 ft while that of Corey was 10,004 ft. Therefore, they started on different trails.
B. Melissa hiked up the trail for a longer period of time than Corey. - TRUE
Rationale: It took Melissa 90 mins to reach the highest elevation of 12,921 while it took just 60 mins for Corey to teach same elevation height at 60 mins
C. Melissa and Corey crossed paths between 60 and 90 minutes. - TRUE
Rationale: As Melissa was still ascending between 60 - 90 mins from 11,239 to 12,921, Corey was descending at the same time . So their path crossed.
D. Corey began his descent before Melissa. - TRUE
Rationale: Corey started descending earlier at 60 mins before Melissa
E. As Melissa’s time increased from 0 to 60 minutes, her elevation decreased. - FALSE
Rationale: as Melissa's time increased from 0 to 60 mins, her elevation increased also from 8,342 ft to 11,239 ft.
Answer:
A) Melissa and Corey started on different trails.
B) Melissa hiked up the trail for a longer period of time than Corey.
D) Corey began his descent before Melissa.

Annie buys some greeting tickets cards. Each card costs $1.75. She pays with with a twenty dollor bill. Let N represent the number of greeting cards annie buys. Write an expression that represents the amount of change annie shall receive.
Answer:
$20 - $1.75N
Step-by-step explanation:
the amount of change she receives is equal to the amount she paid less the total value of cards
total value of cards = price per card x total quantity of cards bought
$1.75 x N = $1.75N
Amount of change = $20 - $1.75N
If she buys 10 cards, the amount of change she receives would be
$20 - $1.75(10) =
20 - 17.5 = 2.5
