D. 90°
Answers
Answer:
d
Step-by-step explanation:
Answer:
D. 90
Step-by-step explanation:
So you're given 130 degrees. that 130 angle and the angle inside the triangle next to it, are supplementary which means they add up to 180. So you have a 40 degree and a 50 degree angle + x. together they must add up to 180
40+50+x=180
90+x=180
x=90

Mario got a part time job mowing lawns. On Monday he charged his neighbor $25 to mow his lawn, then spent $6 to refill his lawn mower with gas. The next day he mowed his Grandparents yard for $20. How much money does Mario have after mowing both yards?
Answers
Answer:
$39Step-by-step explanation:
Step one:
He charged $25 and spent $6 on gas on Monday.
then he made 25-6= $19 mowing his neighbor's lawn.
the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).
So he mowed his Grandparents yard for $20.
total money saved for Monday and Tuesday is
19+20= $39
Hence he has $39 for mowing both yards

Ben, Joe and Alex bought flowers for their girlfriends at the same store.
Ben bought 5 roses, 8 daisies, and 2 carnations for $14.50. Alex bought
3 roses, 12 daisies, and 1 carnation for $14.00. Joe bought 10 roses, 1 daisy
and 3 carnations for $17.25. How much was one rose and one carnation?
rose:
carnation:
Answers
Answer:
1 rose cost $1.5
1 carnation cost $0.5
Step-by-step explanation:
Let the price for one rose be r, price for one daisies be d and the price for one carnation be c
For Ben;
5r + 8d + 2c = 14.5
For Alex
3r + 12d + c = 14
For Joe
10r + d + 3c = 17.25
From equation iii;
d = 17.25- 10r - 3c
Insert this into the first two equations;
5r + 8(17.25-10r-3c) + 2c = 14.5
5r + 138 - 80r -24c + 2c = 14.5
-75r -22c = -123.5
Thus;
75r + 22c = 123.5
Insert the formula for d in the second equation;
3r + 12(17.25-10r-3c) + c = 14
3r + 207 - 120r -36c + c = 14
-117r-35c = 14-207
117r + 35c = 193
So we have two equations to solve simultaneously;
75r + 22c = 123.5
117r + 35c = 193
Multiply first equation by 35 and second by 22
2625r + 770c = 4322.5
2574r + 780c = 4246
Subtract second from first
51r = 76.5
r = 76.5/51
r = 1.5
Insert this in the equation below;
75r + 22c = 123.5
75(1.5) + 22c = 123.5
112.5 + 22c = 123.5
22c = 123.5-112.5
22c = 11
c = 11/22
c = 0.5
During the big storm, 29 in. of snow fell in 8 hours. Find the rate of snowfall in inches per hour.
Answers
Answer:
3 5/8 inches of snow per hour
Step-by-step explanation:
29 divided by 8 = 3.625
(3 5/8)
if 29 inches for 8 hours, and you need to find how much snow in one hour, you can get 1 hour from 8 hours by doing 8 divided by 8. You use the same number to find the snow, divide 29 by 8 and you get the rate at which snow builds up.

Answers
First we find the value of [tex]x[/tex]. This is quite simple as it's a right angled triangle with one of the angles already given. The main concept is vertically opposite angles meaning if 2 lines intersect, the opposite 2 angles are equal.
So the angle [tex]55x - 1[/tex] is for the interior of the triangle too. Now due to angle sum postulate, [tex]36x + 55x -1 + 90 = 180[/tex]
Simplify this and you get: [tex]91x = 91[/tex]
Hence, [tex]x = 1[/tex]
Now, we need to find the value of angle [tex]A[/tex] which is [tex]36x[/tex] which is basically [tex]36 * 1[/tex] when we replace [tex]x[/tex] with [tex]1[/tex].
Henceforth, angle [tex]A[/tex] is equal to [tex]36[/tex] so option [tex]C[/tex] is correct. :D
===================================================
Explanation:
Place point B at the intersection of the lines where the 90 degree angle is located.
Place point C at the other intersection point.
So we have triangle ABC.
Since we have a right angle, this means angle B is 90 degrees.
Angle C is 55x-1 degrees because it's vertical to the angle shown. Vertical angles are congruent.
See the diagram below.
-------------
From here we use the idea that all three angles of any triangle always add to 180
A+B+C = 180
(36x) + (90) + (55x-1) = 180
91x+89 = 180
91x = 180-89
91x = 91
x = 91/91
x = 1
Use this x value to find angle A and C
A = 36x = 36*1 = 36
C = 55x-1 = 55*1-1 = 54
Finding angle C is optional since your teacher just wants angle A, but it's useful to help check our answer
A+B+C = 36+90+54 = 180
So this confirms we have the right x value.

Pls factorise x²-7x+12
Answers
Step-by-step explanation: The first thing you're going to probably
try to do here is to factor out a greatest common factor.
The problem is, there is no factor that is in common
to all three of these terms so you may think it's unfactorable.
However, this trinomial is in a special form.
We have an x squared term, an x term, and a constant term.
When a trinomial is in this form, it can be
factored as the product of two binomials.
So start by setting up two sets of parentheses.
Inside each set, we will have the two terms that compose each binomial.
So we have ( )( ).
The first term is a factor of the x² term, x · x.
For the second term, we need factors of 12 that add to -7.
Since the middle term is negative, we use the negative factors of 12.
Notice that -4 and -3 add to -7 and multiply to be 12.
So our answer is (x - 4)(x - 3).

Beth has $400 in the bank. She paid a start-up fee of $45 plus $3 every time she rides the bus. Write and solve an equation to determine how many times she can ride the bus.
Answers
Answer:
The equation is: y=(x-45)/3 and Beth can ride the bus 118 times.
Step-by-step explanation:
From the information provided, the total cost of riding the bus is equal to the start-up fee plus the cost of each ride for the number of times Beth rides the bus:
x=45+3y, where x is the total cost of riding the bus and y is the number of times Beth rides the bus.
Now, you can solve for y and you can replace x with 400 that is the total amount Beth has:
x=45+3y
y=(x-45)/3
y=(400-45)/3
y=355/3
y=118
According to this, the answer is that the equation is: y=(x-45)/3 and Beth can ride the bus 118 times.

Part A The 4th bubble y= -55x+1630
Part B 1630
Part C 55
Step-by-step explanation:
Part A Use slope to find answer. In this example, points (1,599) and (4,1430).
Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4 which equals 169/-3 and that equals -56.3333333333333333333333. Since y= -55x+1630 is closer, choose that answer.
Part B use y intercept. The y intercept is 1630
Part C Use the slope -55. It decreases by 55.
