Answer:
second option ∠C = 60 degrees
Step-by-step explanation:
To find the angle C
we know that the sum of all interior angles of triangle is 180
∠A + ∠B + ∠C = 180 (sum of interior angles)
90 + 30 + ∠C = 180
120 + ∠C= 180
∠C = 180 - 120
∠C = 60
Answer: B. 60
Concept:
Here, we need to know the idea of the triangle angle sum theorem.
The triangle angle sum theorem states that the sum of interior angles is 180 degrees.
Step-by-step explanation:
Given information
∠A = 90°
∠B = 30°
∠C = unknown
Given expression deducted from the triangle angle sum theorem
∠A + ∠B + ∠C = 180
Substitute values into the expression
90 + 30 + ∠C = 180
Combine like terms
120 + ∠C = 180
Subtract 120 on both sides
120 + ∠C - 120 = 180 - 120
∠C = [tex]\boxed{60}[/tex]

The track team needs new uniforms. the students plan to sell candies. the students find three companies for 44.80. company c charges
Answer: Answer:
Company C
Step-by-step explanation:
Company A sells 12 tigers for $33.24.
Cost per tiger = $33.34 / 12
= $2.78
Company B sells 16 tigers for $44.80. Company
Cost per tiger = $44.80 / 16
= $2.8
C charges $41.10 for 15 tigers.
Cost per tiger = $41.10 / 15
= $2.74
The company that has the best buy is company C that charges $2.74 per tiger

Randy and Trey take turns cleaning offices on the weekends. It takes Randy at most 4 hours to clean the offices. It takes Trey at most 6 hours to clean the offices. What is the greatest amount of time it would take them to clean the offices together?
2.4 hours
2.5 hours
3.0 hours
4.0 hours
The answer is supposedly 2.4 hours, but how ?? Please explain. Thanks!
In one hour Randy cleans at least 1/4 of the offices and in one hour Trey cleans at least 1/6 of the offices.
Working together they would clean at least 1/4 + 1/6 = 5/12 of the offices.
Let x be the greatest amount of time it would take them to clean the offices together. Then we can write the following equation:
5x/12=1

(-4, 6) and (3,-7)
Find the distance between each pair of points
Answer:
14.76482306
Step-by-step explanation:
distance equals the square root of (x2-x1)^2 + (y2-y1)^2.
think of your ordered pairs as set 1 and set 2. (-4, 6) would be set 1 and (3, -7) would be set 2. so your equation will look similar to: (3- -4)^2 + (-7-6)^2 then you square root the whole thing and you will have your answer.

Answer:
Mid point of A(9,2) and B(6,44) is (7.5, -1)
Step-by-step explanation:
I. If mid point = [tex]\frac{x_{a} +x_{b} }{2}[/tex], [tex]\frac{y_{a}+ y_{b} }{2}[/tex]
So (x) = (9 + 6) / 2 = 7.5
(y) = (2 + (-4)) / 2 = -1
So (x,y) = (7.5, -1)

anyone know this question: 16) -8(-21 - 2) - 6
Answer:178
Step-by-step explanation:
distribute, multiply -8 with - 21 and -2 . that would get you 168 + 16 - 6. add the 168 and 16, it equals 184, then subtracts it with a 6.
Make the number 16 using six "1"s. Example: Make the number 18 using six "1"s. A: (11-1-1)(1+1)= 18
Find the 7th term of the geometric sequence shown below
10x^3, 40x^8, 160x^13,…
Answer:
[tex]a_7=40960x^{33}[/tex]
Step-by-step explanation:
Geometric sequence has explicit form:
[tex]a_n=a \cdot r^{n-1}[/tex] where [tex]a[/tex] is first term and [tex]r[/tex] is the common ratio.
First term here is [tex]a=10x^3[/tex] and [tex]r[/tex] could be found by doing second term divided by first term, [tex]\frac{40x^8}{10x^3}=4x^5[/tex].
Therefore the [tex]n[/tex]th term is given by
[tex]a_n=10x^3 \cdot (4x^5)^{n-1}[/tex].
So the [tex]7[/tex]th term is given by
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex].
Let's simplify:
[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex]
[tex]a_7=10x^3 \cdot (4x^5)^{6}[/tex]
[tex]a_7=10x^3 \cdot (4^6(x^5)^6)[/tex]
[tex]a_7=10x^3 \cdot (4096x^30)[/tex]
[tex]a_7=40960x^{33}[/tex]
I am a three-digit number
My second an last digit are the same
The product of the digit of the numbe one less than me is not zero
The number one less than me is divisible by 45
Please help me solve this riddle. Thank you.
Answer:
766?
Step-by-step explanation:
Answer and Step-by-step explanation:
Three Digit Number.
***
Second digit = Last digit
*xx
I multiplied 45 from numbers 1-23, with 22 being the maximum # to multiply to get a 3 digit number that is divisible by 45, and 3 being the minimum # to multiply to get a 3 digit number that is divisible by 45.
Now to check which number it is.
When you multiply 45 by 17, you get 765. This number is supposed to be 1 less than the riddle's number. It also has to have the last 2 digits be the same.
So, lets add one to 765 to see if we solved the riddle.
765 + 1 = 766
766 is the answer!

If 8(x - 2y) = 16x, then what is x in terms of y?
Answer: y = -1/2x
8(x - 2y) = 16x
8x -16y = 16x
-16y = 16x-8x
-16y = 8x
-16y/-16= 8x/-16
y = -1/2x
the expression for perimeter of a rectangle
with a length of (x + 7) and a width of (2x)
Answer:
P = 6x + 14
Step-by-step explanation:
P = 2l + 2w
where P is perimeter, l is length, and w is width
l = x + 7
w = 2x
So P = 2(x+7) + 2(2x)
Distribute the 2 to the x and 7.
P = 2*x + 2*7 + 2*2x
Multiply each term out
P = 2x + 14 + 4x
Group the xs
P = 2x + 4x + 14
Combine like terms
P = 6x + 14

Explanation:
Point C is located at (-6,3). The x coordinate is x = -6.
Going from x = -6 to x = -1 is 5 units to the right. We move another 5 units to the right to go from x = -1 to x = 4 when arriving at its reflected location (4,3). The y coordinate stays the same the entire time.

Geometry question. “Find the value of x that will make A||B.” Brainliest to whoever is correct
Answer:
Step-by-step explanation:
The two angles are interior angles on the same side of the transversal. They are supplementary.
2x + 50 + 5x - 80 = 180 Combine like terms
7x - 30 = 180 Add 30 to both sides
7x = 210 Divide by 7 on both sides
x = 210/7
x = 30
Are 8x²y and -5yx2 like terms? Explain.
Answer:
In algebra, like terms are terms that have the same variables and powers. ... Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
Answer:
These are not like terms.
Step-by-step explanation:
Although their variables are the same, the exponents are different. LIke terms must have the same variables AND same exponents. The first term's variables are: x raised to the second power times y, while the other term's variables are: y times x times 2
