In triangle ABC, m ZA = 47°, m ZB = 62°. m ZC =
a. 81°
b. 61°
C. 71
d. 51°
Answer:
m ZC = 71 degrees. Option C.
Step-by-step explanation:
Triangles always measure a total of 180 degrees.
47 + 62 + c = 180
109 + c = 180
c = 71
Answer:
71°
Step-by-step explanation:
The total angles in a triangle should equal 180°
a + b + c = 180
47 + 62 + c = 180
109 + c = 180
180 - 109 = 71
c = 71°

2x2 + 2x - 1 when x = -3
Answer: 11
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
x = -3
Given expression
2x² + 2x - 1
Substitute values into the expression
=2(-3)² + 2(-3) - 1
Simplify exponents
=2(9) + 2(-3) - 1
Simplify by multiplication
=18 - 6 - 1
Simplify by subtraction
=12 - 1

hope it is help fullMark me a brainlistGrace and her dad are planning to attend the state fair. An adult ticket is $15.00. The price of an adult ticket is one half the price of a student ticket plus $8.00. Write an equation to determine how much Grace will pay for a student ticket.
one halfx + 8 = 15
one halfx − 8 = 15
one halfx + 15 = 8
one halfx − 15 = 8
Answer:
Option 1 is the correct equation.
Step-by-step explanation:
x = price of the student ticket.
One half price of x + $8 = adult ticket price ($15)
Answer:
The correct answer is A
Because taking the student ticket to be x
one half of x + 8 =15

Answer:
Bot 2
Step-by-step explanation:
Lets find both robots rate per second.
Bot 1:
16 / 2 = 8 clicks per second
Bot 2:
30 / 3 = 10 clicks per second
Now multiply by 10 to see who clicks the most.
Bot 1:
8 * 10 = 80 clicks in 10 seconds
Bot 2:
10 * 10 = 100 clicks in 10 seconds.
With this information, its clear that bot 2 clicks the most in the least amount of time.
Best of Luck!

You have $200 in a savings account and $100 in a checking
account. Each week, you add $50 to your savings account and $30 to your
checking account.
a. Write algebraic expressions that represent the amount of money in each
bank account after w weeks.
b. Write an expression in simplest form that represents the total amount of
money in both accounts after w weeks.
c. How much money do you have in both accounts after 5 weeks?
Answer:
a. Savings account: 200 + 50w Checking account: 100 + 30w
b. 300 + 80w
c. 700
Step-by-step explanation:
b. 200 + 50w + 30w + 100 Combine like terms. 300 + 80w
c. 300 + 80w. w=5. 300 + (80*5) = 300 + 400 = 700

find the distance between each pair of points
-6 -5 2 0
Hi, I'm happy to help!
To solve this, we need to find the distance in x coordinate values, y coordinate values, then use the Pythagorean Theorem to solve for the distance.
First, let's find the distance in x coordinate values. Our first x coordinate value is -6, and our second is 2. From here, we subtract.
-6-2=-8
Since we have a negative number, we use absolute value, which says how far the number is from 0.
I-8I
8
The distance in x coordinate values is 8.
Next, we find the distance in y coordinate values. our first y coordinate is -5, and our second is 0, now, let's subtract.
-5-0=-5
I-5I
5
The distance in y coordinate values is 5.
From here, we use the Pythagorean Theorem, which states that a²+b²=c².
This has to do with right triangles. Think about drawing a line down to the y coordinate of the other point, then to the x coordinate. Now, drawing a line straight from point to point. Now, you have a right triangle, and we are trying to find c, the direct distance of the line going from point to point. Let's say that our x distance is a, and our y distance is b.
Let's plug in the values:
8²+5²=c²
64+25=c²
89=c²
To find c, we need to find the square root of 89.
√89=c
9.433981132...=c
Since this number goes on forever, we need to round.
Rounding to the nearest thousandth:
9.434
Nearest hundredth:
9.43
Nearest tenth:
9.4
Depending on what the question asks, use one of these values.
To conclude, The distance between the two points is about 9.43 units.
I hope this was helpful, keep learning! :)

I need to find the csc A, sec A, and cot A.
Step-by-step explanation:
the length of AB = √10²+7²=√149

csc A = AB/BC = √149/ 7
sec A = AB/AC = √149/ 10
cot A = AC/BC = 10/7

Answer:
15
Step-by-step explanation:
you can add the absolute value of -7 with 8 so it's 15
The length of AD on the number line is,
⇒ AD = 15
What is mean by Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
We have to given that;
Number line is shown in figure.
And, The point A is at - 7 on number line.
The point D is at 8 on number line.
Hence, We get;
The length of AD on the number line is,
⇒ AD = | - 7 - 8 |
⇒ AD = | - 15 |
⇒ AD = 15
Therefore, The length of AD on the number line is,
⇒ AD = 15 units
