The only measure that is possible for the other two angles is 40 degrees.
What is triangle ?
Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.
Let's call the two other angles in the isosceles triangle "x". We know that the sum of the three angles in a triangle is always 180 degrees. Therefore, we can set up an equation:
100 + x + x = 180
Simplifying this equation, we get:
2x + 100 = 180
Subtracting 100 from both sides, we get:
2x = 80
Dividing both sides by 2, we get:
x = 40
So the other two angles must both measure 40 degrees.
None of the other choices (80, 100, or 50 degrees) are possible for the other two angles in an isosceles triangle with one angle measuring 100 degrees.
Therefore, the only measure that is possible for the other two angles is 40 degrees.

Where is the mistake she made and explain why please help??????????????
The first mistake is that she went from 3x-2 to 3x+2. Everywhere you see "3x+2", change it to "3x-2".
Another mistake is we shouldn't use absolute value in this case. This is because we're dealing with an odd number index. In this case, the index of the root in the original equation is 3. Because there isn't any absolute value, we won't have a plus/minus.
So we should have 3x-2 = 8 for the third to last step. That solves to x = 10/3 as the only solution.

Write and solve an equation to answer the following question. The Smith family rented a recreational vehicle for a seven-day vacation. The cost to rent the recreational vehicle was $560 plus $0.50 per mile. How many miles were driven if the total cost was $1350?
a. 790 mi
b. 1580 mi
c. 395 mi
d. 3820 mi
Answer:
1580 miles
Step-by-step explanation:
We can represent the total cost for the rental with the equation d=560+0.5m where d is the cost and m is the miles driven. We know this equation works as 560 is the fixed cost, and it costs $0.5 per mile, and in math, "per" means multiplication.
Now we can solve for m as we know that d=1350 in this case.
Solving we get:
1350=560+0.5m
790=0.5m
1580=m
Thus, they drove 1580 miles.

Leo invested $1900 in an account with annually compounded interest. After 3 years, he had $2275 in the account. What was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign.
Answer:
6.2
Step-by-step explanation:
Use the formula for calculating compound interest PN=P0(1+rk)Nk where r is the unknown, PN=2275, P0=1900, k=1, and N=3. Substitute the values into the formula and simplify.
2275=1900(1+r1)3⋅1
Let's simplify within the parenthesis and the exponent.
2275=1900(1+r)3
Divide both sides by 1900.
22751900=(1+r)3
To isolate the variable, take the cube root of each side.
22751900−−−−−√3=1+r
Subtract 1 from each side to get r by itself.
22751900−−−−−√3−1=r
Simplify for an answer of r≈0.062 which is the interest rate 6.2%.

Dylan is playing with a see-saw on the playground. He puts a piece of tape at specific distances from the center of the see-saw so that there ratio of the distance between the center and the tape and the distance between the center and the right end is always a common fraction. Dylan then records the relationship between the height of the tape and the height of the left end of the see-saw, relative to a neutral position.
Use the pattern you observe in the table below to correctly complete Dylan’s conjectures.
distance from center to tapedistance from center to right end
height of tape
(centimeters)
height of left end
(centimeters)

If the tape is placed at 13 of the distance between the center and right end, when the left end is at a height of 18 centimeters, relative to a neutral position, the tape will be at a height of
centimeters, relative to a neutral position.
If the tape is placed at 14 of the distance between the center and right end of the see-saw, then the height of the left end will be
times the height of the tape, relative to a neutral position.

If Q(x) = 6x2 - 1, find Q(-7).
Answer:
[tex] \huge \boxed{Q( - 7) = 293}[/tex]
Step-by-step explanation:
[tex]Q(x) = {6x}^{2} - 1[/tex]
To find Q(-7) , insert the value of x that's - 7 into Q(x). That is for every x in Q(x) , replace it with - 7
We have
[tex]Q( - 7) = 6 ({ - 7})^{2} - 1 \\ = 6(49) - 1 \\ = 294 - 1[/tex]
We have the final answer as
[tex]Q( - 7) = 293[/tex]

Diego scored 100 points less than Maria on a game. Maria scored 850 points on the game. Which expression shows the number of points Diego scored?
A. 850+100
B. 850 -100
C. 85+100
D. 85-100
Answer:
B. 850-100
Step-by-step explanation:
Less than means you should take away (subtract). Since Diego scored less than Maria you are taking the number of points Diego got away from Marias points. So it would be 850 take-away 100, or 850-100.
The sum of interior angles in a triangle are 180 degrees. Angle B and C are congruent. Angle B is twenty less than angle A. Write and solve a system of equations using substitution. Write and solve a system to determine the measure of angles A, B, and C.
Answer:
[tex]A = \frac{220}{3}[/tex]
[tex]B = \frac{160}{3}[/tex]
[tex]C = \frac{160}{3}[/tex]
Step-by-step explanation:
Given
[tex]A + B + C = 180[/tex]
[tex]B = C[/tex]
[tex]B = A- 20[/tex]
Required
Solve for A, B and C
The equation binding A, B and C have been written out (above)
Substitute C for B in [tex]A + B + C = 180[/tex]
[tex]A + B + B = 180[/tex]
[tex]A + 2B = 180[/tex]
Substitute A - 20 for B
[tex]A + 2(A - 20) = 180[/tex]
[tex]A + 2A - 40 = 180[/tex]
[tex]3A - 40 = 180[/tex]
Solve for 3A
[tex]3A = 180 + 40[/tex]
[tex]3A = 220[/tex]
[tex]A = \frac{220}{3}[/tex]
Solve for B in [tex]B = A- 20[/tex]
[tex]B = \frac{220}{3} - 20[/tex]
[tex]B = \frac{220 - 60}{3}[/tex]
[tex]B = \frac{160}{3}[/tex]
Recall that [tex]B = C[/tex]
[tex]C = \frac{160}{3}[/tex]
