Answer:
65
Step-by-step explanation:
Angle A is 55 degrees.
A triangle adds up to 180 in degrees so 60 + 55 = 115
180 - 115 = 65 therefore angle C is 65 degrees.
Angle B is equal to angle C so it's also 65 degrees.
Basically:
A - 55
B - 65
C - 65

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Answer: The perimeter of crater lake is 17.27 miles.
Step-by-step explanation:
The shape of the lake is like a circle
The diameter of lake = d = 5.5 miles
∵ shape pf lake is circle, so the diameter of circle = d = 5.5 miles
Let The perimeter of crater lake = p miles
Now, As we know
The perimeter of circle = \pi × diameter
the value of \pi = 3.14
Or, p = pi × d
Or, p = pi × 5.5 miles
Or, p = 3.14 × 5.5 miles
∴ p = 17.27 miles
So, The perimeter of circle = perimeter of lake = p = 17.27 miles
Hence, The perimeter of the crater lake is 17.27 miles.

the parent’s height is 9 cm and the child’s height is 6 cm.
The child’s actual height is 1.3 m.
What is the actual height of the parent?
Answers
Answer:
1.95 m
Step-by-step explanation:
The ratio between the parent's height and the child's height stays the same.
Therefore, 9:6 = 1.5:1.
1.5:1 = x:1.3
Hence, after calculation, the parent's height is 1.95 m.

There are 2 red, 5 green, 3 blue, and 4 white points on a circle. Find the number of line segments which have vertices of different colors at the given points.
Answers
Answer:
Step-by-step explanation:
The number of those line segments which have endpoints of different colors is 47.
What is permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
There are 5 red, 4 green, and 3 blue points on a circle.
There are different colored endpoints on each line segment that starts at a red point and travels to either a green point or a blue point.
There are 5 red points and 7 segments from each of them, making a total of 35 segments.
There are different colored endpoints on each line segment that leaves at a green point and travels to either a red or blue point.
There are 4 green points and 8 segments from each, for a total of 32 segments.
There are different colored endpoints on each line segment that leaves at a blue point and travels to either a green point or a red point.
Each blue point has 9 segments, and there are a total of 5 blue points.
Add all the ways = 35 + 32+ 27
= 94 segments.
Number of segment = 94/2 = 47
Thus, the number of those line segments which have endpoints of different colors is 47.
There are 7 segments from each red point and there are 5 red points, for a total of 35 segments.
Each line segment from a green point that goes to either a red point or a blue point has endpoints of different colors.
There are 8 segments from each green point and there are 4 green points, for a total of 32 segments.
Each line segment from a blue point that goes to either a green point or a red point has endpoints of different colors.
There are 9 segments from each blue point and there are 5 blue points, for a total of 27 segments.
Adding these together, we get 35 + 32+ 27 = 94 segments.
However, we have counted each segment twice, so we need to divide that answer by 2: 47 segments.

D. The cost of attending a concert for c groups of people for $6.50 each.
Answers
Answer:
B
Step-by-step explanation:
You pay $117 no matter how many kids show up and then you pay an additional fee of 6.50 per kid.
1 kid
y = 6.50(1) + 117
y = 123.50
If 10 kids come
y = 6.50(10) + 117
y = 65 + 117
y = 182
You can use this equation to help you figure out how much it will cost you depending on how many kids you invite.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

The sum of 4 consecutive integers is 130 what is the third number in the sequence
PLZ HELP!!!
Answers
Answer:
33
Step-by-step explanation:
We can write an equation:
x+x+1+x+2+x+3=130
x represents the smallest number of the consecutive integers
By the way, an example of consecutive would be 2, 3, 4, 5 or 10, 11, 12, 13
We can combine like terms from our equation:
4x+6=130
4x=124
x=31
The smallest number is 31. The second number would be 31+1=32, which means the third number is 33!
Hope this helps! :) :)
Answer:
\(\huge\boxed{3rd\ number = 33}\)
Step-by-step explanation:
Let the consecutive numbers(Coming one after another) be x, x+1, a+2 and x+3
So,
x+x+1+x+2+x+3 = 130
4x + 6 = 130
Subtracting 6 to both sides
4x = 130-6
4x = 124
Dividing both sides by 4
x = 32
So,
1st number = x = 31
2nd Number = x+1 = 31+1 = 32
3rd number = x+2 = 31+2 = 33
4th number = x+3 = 31+3 = 34
