Both these angles are vertically opposite angles due to which their angle measures will be equal .
Which means :-
[tex]12x + 9 =13 x + 1[/tex]
[tex]9 = 13x + 1 - 12x[/tex]
[tex]9 = 1x + 1[/tex]
[tex]1x + 1 = 9[/tex]
[tex]x + 1 = 9[/tex]
[tex]x = 9 - 1[/tex]
[tex]x = 8[/tex]
Which means :-
angle 12x + 9 == 12 × 8 + 9
= 96 + 9
= 105°
angle 13x + 1 == 13 × 8 + 1
= 104 + 1
= 105°
Therefore :-
angle 12x + 9 = 105° ( x = 8)
angle 13x + 1 = 105° ( x = 8 )

Step-by-step explanation:
1. Becky won $108,000 by coming in first place at a chess tournament, and she has the option of receiving 4 quarterly payments of $27,000, with the first payment in 3 months, or 1 lump-sum payment of $108,000 occurring in 12 months. Once she receives her money, she plans on putting it in a savings account paying simple interest at an annual interest rate of 8.8% calculated quarterly. Becky's financial adviser told her that she'll "lose" money if she takes the lump-sum payment, and Becky wants to calculate how much she’ll "lose". HELP !! I don’t understand ! please show work
Answer:
Step-by-step explanation:
From the information being provided;
We learnt that Becky pays simple interest at an annual interest rate of 8.8% which is calculated quarterly.
i.e. [tex]\dfrac{8.8\%}{4}= 2.2\%[/tex]
Since the first payment of $27,000 happened in the first three months, therefore, Becky will be able to have the money in the bank for 3 quarters prior to the lump-sum payment gets started.
Thus, the estimate of the amount Becky would earn as interest during this period of time is as follows:
[tex]I =\dfrac{PRT}{100}[/tex]
[tex]I =\dfrac{27000\times 2.2 \times 3}{100}[/tex]
[tex]I =\dfrac{178200}{100}[/tex]
I = $1,782

Find the Perimeter of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place
Step-by-step explanation:
diameter of semicircle is 6 so radius is 6/2=3
so perimeter of the circle would be
p=2πr
p=2π*3=6π=18.8
But we have a semicircle so perimeter will be
P=p/2=18.8/2=9.4
The perimeter of the figure now would be
Perimeter=9+8+8+9.4=25+9.4=34 approximately.
The perimeter of the figure below, composed of an isosceles trapezoid and one semicircle is 34.4 units.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
From the given figure, equal sides of an isosceles trapezoid is 8 units, and parallel sides are 9 units and 6 units.
Radius of semicircle is 6/2 = 3 units
Now, perimeter = 9+8+8+Circumfrence of a semicircle
= 25+πr
= 25+3.14×3
= 25+9.42
= 34.4
Therefore, the perimeter is 34.4 units.

Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty while driving through Canada Samuel notice that each gas station measures its gasoline in litres instead of gallon Samuel found that one is approximately equivalent to 0.264 gallons how many liters would it take to fill Samuels car round to the nearest tenth of a liters
Answer: 47.4 liters
Step-by-step explanation:
From the question, we are informed that Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty and while in Canada, he noticed that one liter is equivalent to 0.264 gallons.
The number of liters it'll take to fill Samuels car will be:
= 12.5/0.264
= 47.4 litres
Suppose that you and a friend are playing cards and decide to make a bet. If your friend draws two black cards in succession from a standard deck of 52 cards replacing the first card, you give him $30. Otherwise, he pays you $20. If the same bet was made 20 times, how much would you expect to win or lose? Round your answer to the nearest cent, if necessary.
Answer:
I am expected to win $150
Step-by-step explanation:
We need to calculate the probability of drawing 2 black cards with replacement
There are 26 black cards in a deck of cards
The probability of drawing a black card is thus 26/52 = 1/2
So the probability of drawing two black cards in succession with replacement will be 1/2 * 1/2 = 1/4
So the probability of not drawing the two in succession will be 1 - 1/4 = 3/4
so out of twenty trials the number of times the drawing will occur will be 1/4 * 20 = 5 times
The number of times it will not occur will be 20-5 = 15 times
The amount my friend will win will be 5 * 30 = 150
The amount I will win will be 20 * 15 = 300
The amount I expect to win in the deal will be 300-150 = $150

Hi, could someone give me the correct answer i really need it and i'd appreciate it so much. Can anyone please help?
Answer:
a= c+16
a-c= 16
Step-by-step explanation:
a = b + 12
b = c + 4
adding both eq.s, we get:
a+b = b+c+12+4
a+b = b+c+16
a = c+16
a-c = 16
Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future.
Complete Question:
Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?
s(t)•h(t)= (3x-4)(2x-8)
= 6x² - 24x -8x - 32
= 6x² - 32x - 32
Answer:
Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.
Advice: Jamie should take note of the rule that applies when multiplying signs.
Step-by-step Explanation::
To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:
s(t)•h(t)= (3x-4)(2x-8)
Using distributive property, do the following:
[tex] 3x(2x - 8) -4(2x - 8) [/tex]
[tex] 3x*2x -3x*8 -4*2x -4*-8 [/tex]
[tex] 6x^2 - 24x - 8x + 32 [/tex] (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)
Add like terms
[tex] 6x^2 - 32x + 32 [/tex]
Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.
Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.

1) x+3= -7
2) 2/3x+1=27
3) 4x-7=2(x+3)+9
Answer:
1) x = -10
2) x = 39
3) x = 11
Step-by-step explanation:
1) x + 3 = -7
=> x= -7-3
=> x= -10
2) 2/3x + 1 = 27
=> 2/3x = 27 - 1
=> 2x =26 * 3 (26 multiply by 3)
=> x = 78/2
=> x =39
3) 4x-7 = 2 (x+3) +9
=> 4x-7 = 2x+6+9
=> 4x-2x =7+6+9
=> 2x = 22
=> x =22/2
=> x = 11
At the ski shack, customers can rent,skis, snowboards, boots, and poles by the day Mrs.Alvarez is renting skis and poles she has a 18$ coupon off
which expression represents the total cost for Mrs.Alvarez to rent skis for s days and poles for p days
Answer: 48s+12p-18 this is the correct answer i just took the test
The expression that represents the total cost can be written as -
y = as + pb - 18.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that at the ski shack, customers can rent, skis, snowboards, boots, and poles by the day. Mrs. Alvarez is renting skis and poles.
Assuming the cost to rent skis for 1 day is $a and the cost of renting the poles is $b. Then we can write the expression that represents the total cost as -
y = as + pb - 18
Therefore, the expression that represents the total cost can be written as - y = as + pb - 18.

The first step is to subtract 2a from both sides to get the equation 2x=4b-2a

Which measure of center should Sydney choose so she can have the highest percentage possible?
O Sydney should choose the mean after dropping one test score.
O Sydney should choose the mean without dropping one test score.
O Sydney should choose the median after dropping one test score.
O Sydney should choose the median without dropping one test score.

Mark this and return
Answer:
The correct answer is:
Sydney should choose the median after dropping one test score.
Step-by-step explanation:
when scores are not dropped:
List of scores = 68%, 84%, 94%, 100%
Mean = (68 + 84 + 94 + 100) ÷ 4 = 86.5%
Median = 68 84 94 100
Median = (84 + 94) ÷ 2 = 89%
Although there are no outliers because Sydney was given the option to drop a test score, dropping the lowest score will increase his overall chances of making a higher score. Therefore, 68% will be dropped.
List of scores when the lowest score is dropped = 94%, 84%, 100%
Mean: (84 + 94 + 100) ÷ 3 = 92.7%
Median: 84, 94, 100
Median = 94% (middle term)
From the four possible scores, the highest score is 94%, and it is gotten by finding the median after dropping a score
