Answers
Answer:
40 degrees
Step-by-step explanation:
We need to find angle 3
Since angle 2 and angle 4 are vertical angles, they will be congruent
To solve for x we can make the following equation:
x+70=2x
x=70
In this problem angles 2 and 3 are supplementary (they add to 180)
Angle 2 is 140 degrees
We can now make the following equation to find angle 3 using measures addition postulate
let angle 3 be x
180-140=x
The 140 is angle 2
x=40

The ratio of fiction to non-fiction books at school library is 3 to 5. If there are 240 books in the library how many non-fiction books are in the library?
Answers
Answer:
150
Step-by-step explanation:
The ratio is 3:5, so you can make this equation:
[tex]3x+5x=240[/tex], because for any integer x, the ratio will stay the same.
solve that:
[tex]3x+5x=240\\8x=240\\x=30[/tex]
We're not down yet!
we need to find 5x, not x.
[tex]5*30=150[/tex]
There are 150 non-fiction books in the library.

150+90=240
The are 150 non-fiction books are in the library.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
The ratio of fiction to non-fiction books at school library is 3 to 5.
Total books = 240
So, the number of non fiction books
= 240 x 5/8
= 30 x5
= 150
Hence, there are 150 non fiction book.

A math book comprises of two sections: arithmetic and geometry in the ratio 5:3. How much of each type of content will be needed to make a book of 480 pages?
Answers
Answer:
Arithmetic content = 300 pages
Geometric content = 180 pages
Step-by-step explanation:
Arithmetic : Geometry = 5 : 3
Total pages of book = 480
How much of each type of content will be needed to make a book of 480 pages?
Total ratio = arithmetic + geometric
= 5 + 3
= 8
Arithmetic content = 5 / 8 × 480
= 0.625 × 480
= 300
Arithmetic content = 300 pages
Geometric content = 3 / 8 × 480
= 0.375 × 480
= 180
Geometric content = 180 pages

The charity gala costs a flat fee of $394, plus an additional $6 per attendee. How many attendees can there be, at most, if the budget for the charity gala is $508?
Answers
Answer:
There can be 19 attendees at most, if the budget for the charity gala is $508.
Step-by-step explanation:
From the information given, the cost of the charity gala is equal to the flat fee plus the additional cost per attendee for the number of attendees, which can be expressed as:
C=394+6a, where c is the cost of the charity gala and a is the number of attendees.
Now, you need to replace C with 508 and solve for a that is the number of attendees:
C=394+6a
508=394+6a
508-394=6a
6a=114
a=114/6
a=19
According to this, the answer is that there can be 19 attendees at most, if the budget for the charity gala is $508.

Step-by-step explanation:
Probability
The simple probability of a random event can be calculated as the ratio between the possible favorable cases and the total possible cases.
The pie chart shows the number of books in Hero's library grouped by category.
The total number of books is 14 + 10 + 4 + 2 = 30
The number of romance books is 2
Thus, the probability of randomly choosing a romance book out of the total books is:

11) How many kilograms of How many kilograms of calcium are there
in 173 pounds of calcium? (1 lb = 454 g; 1
kg 1000 g)
A) 78.5 kg
B) 110 kg
C) 78500 kg D) 1.10 kg
Answers
Explanation. First, we must convert the lbs into grams, we can do this my multiplying 454 by 173 and get 78,500. Then convert it to kg, there are 1,000 g in a kg do divide 78,500 by 1,000 to get 78.5 kg. Let me know if it’s correct so others can use it. Brainliest would be appreciated.
Good luck :)
The kilogrammes of calcium found in 173 pounds of calcium is = 78.5 kg. That is option A.
First convert the 173 pounds of calcium to gramma
1 lb(pounds) = 454 g;
Therefore 173 pounds = 173 ×454
= 78,542g
But, 1000 g = 1kg
Therefore, 78542g = 78542 ÷1000
= 78.542
=78.5kg.
Therefore, the kilogrammes of calcium found in 173 pounds of calcium is = 78.5kg.

Seeing that both triangles are side by side and share a side, we know that that side of both triangles is congruent.
Then when you look at the angles, you will see that one on each triangle has one curved line. This one curved line shows that these angles are congruent.
There is then the two curved lines you can find on both triangles as well. This shows that both those angles are congruent.
With this information, you should be able to tell that two angles of the triangles are congruent, and one side of both triangles are congruent, with the order that these are shown on the triangles being an angle, then a side, then another angle, the answer would be ASA, or angle, side angle.

The radius of a circle is 16.7 in. Find the circumference to the nearest tenth.
Answers
16.7 inches times 3.14 in or pie, equals 52.4 inches, and because you were given the radius and not the diameter, you multiply 52.4 inches by 2 to get 104.9 or 105 inches.
The circumference of the circle is 105 in to the nearest tenth.
What is the circumference of the circle?The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.
The circumference of the circle = 2πr
We are given that the radius of a circle is 16.7 in.
We need to determine the circumference to the nearest tenth.
Radius r = 16.7
Then circumference of the circle = 2πr
= 2 x 3.14 x 16.7
= 104.87
Therefore, the circumference of the circle is 105.
