Add the two angles you already know (for example, 50 and 45), then, with the sum of the two angles (95), subtract it from 180 (180-95) and there's your answer. How do I find the third angle of a triangle if the two known angles are 35 and 40?
The measure of any exterior angle of a triangle is equal to the sum of the measures of its two interior opposite angles. The sum of the three angles of a triangle is 180°. ... The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
all i got (:
Answer:
The largest angle has a measure of 82 degrees.
Step-by-step explanation:
Since the two angles are equal they represent x. Then the largest angle is 33 degrees more so that is represented as x+33. Then you get your equation: 3x+33=180(because each triangle has 180 degrees). Subtract 33 from both sides to get x by itself and you get 3x=147. Then to simplify divide 3 from both sides and you get 49 degrees for x. Since it says in the beginning that the largest angle is the value of x+33 we know that the largest angle is 82 degrees.
One month jenny rented 3 movies and 5 video games for a total of $40. The next month she rented 12 movies and 2 video games for a total of $43. Find the rental cost for each movie and each video game.
movies is 2.59 and videos is 5.944
//Hope this helps
The correct answer is $6.50 for each video game and $2.50 for each movie. My work:
3 x 2.50 = $7.50 and 5 x 6.50 = $32.50
32.50 + 7.50 = $40.00
12 x 2.50 = $30.00 and 2 x 6.50 = $13.00
30.00 + 13.00 = $43.00

Is the point (-10, -34 ) on the line y=3x-4 Show how you know
Answer:
yes
Step-by-step explanation:
Substitute x = - 10 into the equation and if the value obtained equals - 34 then the point satisfies the equation and lies on the line
x = - 10 : y = (3 × - 10) - 4 = - 30 - 4 = - 34 ← agrees
Hence (- 10, - 34) lies on the line y = 3x - 4

What is the value of x so that the line segment with endpoints W(x, −2) and X(5, −4) is parallel to the line segment with endpoints Y(2, 2) and Z(5, 6)?
x equals six start fraction one over two end fraction
x = 6
x equals three start fraction one over two end fraction
x = 7
Answer:
x equals six start fraction one over two end fraction
Step-by-step explanation:
Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.
Slope of YZ is:
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{6-2}{5-2} =\frac{4}{3}[/tex]
Since they are parallel, then WX has a slope of 4/3 too.
Slope of WX is:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3} = \frac{-4--2}{5-x}\\\\\frac{4}{3} =\frac{-2}{5-x}\\\\ (5-x)\frac{4}{3} = -2\\\\ 20 - 4x = -6\\\\-4x = -26 \\\\ x = 6 \frac{1}{2}[/tex]
The price of gas was $1.80 in September then $2.07 in October. Find the percent change from September to October.
twenty seven percent.
The percent change in the price of gasoline from September to October is calculated using the formula for percent change. Subtracting the September price from the October price and dividing by the September price yields a 15% increase.
To calculate the percent change in the price of gasoline from September to October, we use the formula for percent change, which is
(New Price - Old Price) / Old Price
x 100%. In this case, the price in September was $1.80, and the price in October was $2.07.
The percent change can be calculated as follows:
Subtract the old price from the new price: $2.07 - $1.80 = $0.27.Divide the change by the original price: $0.27 / $1.80.Convert this number to a percentage by multiplying by 100, which gives us the percent change: ($0.27 / $1.80)Therefore, the percent change in the price of gasoline from September to October is 15%.
A home appliance salesperson wants to earn a total of 3,600 next month including his base salary and commissions. He earns a base salary of $800 per month and earns 20% commission for all sales in that month. What is the value of the merchandise that the salesperson must sell to reach his goal?
Answer:
He must sell $14000 of merchandise
Step-by-step explanation:
The salesperson earns a base salary of $800
This means that he must make
$3600 - $800 = $2800 worth of commisions
Let x, be the value of the mechandise that he needs to sell.
This means that
x*0.20 = $2800
x = $2800/0.20
x = $14000
He must sell $14000 of merchandise
What is the solution to the following system of equations?
Answer:
D. (2,1)
Step-by-step explanation:
Fill in the value for y from the first eq (6x-11) into the second:
-2x - 3(6x-11) = -7
Now simplify:
-2x -18x + 33 = -7
-20x = -7-33
20x = 40
x = 2
Now that we have x, plug it into the top eq to get y:
y = 6*2 - 11 = 1
Et voila, x=2 and y=1, so the solution is (2,1).
Answer:
X= 2 and Y=1
Step-by-step explanation:
✯Hello✯
↪ So you know what y is so you can substitute into -2x-3y=-7
↪ -20x+33=-7 (thats after you expand the brackets)
↪ -20x=40
↪ this means that x=2. Therefore if u substitute y=1 and its on the options

what is the constant of proportionality for the relationship between the length of the arc intercepted by 80 angle and the radius of the circle ?
Eight hundred thousands
Final answer:
The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.
Explanation:
The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.
This can be determined by using the formula for arc length: L = 2πr(A/360), where L is the length of the arc, r is the radius of the circle, and A is the angle in degrees. Since we know that A = 80 degrees, we can substitute the values into the formula to find the constant of proportionality.
L = 2πr(80/360) = (π/9)r

How much water must be evaporated from 36 ounces of a 8% salt solution to make a 9% salt solution?
To obtain a solution that is 9% salt, how many ounces of water must be evaporated
(Simplify your answer.)
Answer:
4 oz of water must be evaporated
Step-by-step explanation:
If we let x represent the amount of water to be evaporated, the relation between the solutions is ...
0.08 · 36 oz = 0.09 · (36 -x) oz
0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36
x = 36· 0.01/0.09 = 36/9 = 4
4 ounces of water must be evaporated.

Sarah Wood and her husband have agreed to purchase a house for $87,500.00. Washington Savings and Loan is willing to finance the purchase but requires a $5,000.00 down payment and closing costs of 3 percent of the amount of the mortgage loan. What are the total closing costs?
The mortgage loan amount is $82,500. The closing costs are 3 percent of the loan amount. Therefore, the total closing costs are $2,475.
Explanation:Sarah Wood and her husband are purchasing a house for $87,500.00, but they are making a down payment of $5,000.00. Therefore, the mortgage loan amount is $87,500 - $5,000 = $82,500. The closing cost for this mortgage loan is 3 percent of the loan amount. Thus, to calculate the total closing costs, we multiply the loan amount by 3%. Therefore, total closing costs are $82,500 * 0.03 = $2,475.00.
So, total closing costs are $2,475.00.

Does this table show a proportional relationship? If so, what is the constant of proportionality?
x| 3 6 9 12
-------------------------------
y| 12 24 45 60
Answer:
4
Step-by-step explanation:
You can divide all the x from the y like , 45/9 =4 so it equals four
Yes, the table does show a proportional relationship and the constant of proportionality is 4.
What is proportionality?If the corresponding elements of two sequences of numbers have a constant ratio,
Known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
We know constant of proportionality is when we have the same multiplicative or division factor between two variables.
Given, when x = 3, y = 12, So y = 4x.
Again when x = 6 , y = 24, so, y = 4x and from observation we can conclude that y is 4 times of x or y = 4x.
∴ The constant of proportionality is 4.
