Answer:
B, 3/4
Step-by-step explanation:
you can divide the top and bottom by 6
6 * 3 = 18
6 * 4 = 24
so it applies the same for dividing
18/6 = 3
24/6 = 4
If you have trouble dividing by larger numbers, try dividing by two if both the numerator and denominator are even numbers (in this case they are)
Your answer is 3/4

Find the area of each circle with the given radius or diameter. Use 3.14 for pi.
Answer:
Read explanation
Step-by-step explanation:
r=4in 4^2 is 16 then multiply it by 3.14 to get 50.24
r=2in 2^2 is 4 then multiply it by 3.14 to get 12.56
d=2in Since you have the diameter first, you just divide it by 2 and your radius is 1. 1^2 is 1 1*3.14=3.14
r=8in 8^2 is 64 then multiply it by 3.14 to get 200.96
d=12in divided 12 by 2 and you get 6. 6^2 is 36, multiply that by 3.14 to get 113.04

The library labels each book with a five-digit code to identify the book in their computer system. Each code is 3 digits (0-9) followed by two letters. How many codes are possible?
Answer:The number of all possible codes = 26 * 26 * 10 * 10 * 10 = 676000
Step-by-step explanation:
five digit code; each code is 3 digits (0-9) followed by two letters. That's ten numbers to choose from and 26 letters in the alphabet.
The problem suggests numbers and letters can be used more than once, like having a code: 555AA
To find the number of possible codes, you multiply by the choices for each digit.
10*10*10*26*26 = 676,000
Answer:
26 * 26 * 10 * 10 * 10 = 676000

If each square that is broken into 100 parts is considered a whole, which model represents 0.68 of 2? 2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray. 2 models divided into 100 parts. Left: 70 are shaded dark gray. 30 are shaded light gray. Right: 0 are shaded dark gray. 40 are shaded light gray. 2 models divided into 100 parts. Left: 60 are shaded dark gray. 40 are shaded light gray. Right: 20 are shaded dark gray. 20 are shaded light gray. 2 models divided into 100 parts. Left: 100 are shaded gray. Right: 100 are shaded gray.
2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.
=====================================================
Explanation:
Consider the problem of 0.68 of 1, in other words 0.68*1 or simply 0.68
The number 0.68 is 68/100 or 68 over 100. We can have a 10 by 10 grid of tiny squares. Shade in 68 of them to represent 0.68 aka 68 hundredths.
So you'd have 6 full rows shaded (to account for 0.60 so far) and then an additional 8 squares in the seventh row (adding on 0.08 to get 0.60+0.08 = 0.68)
All of this is for one square. Double this process and you'd get 0.68*2 to represent the value 1.36
In total, 2*68 = 136 squares are shaded out of 2*100 = 200 squares total.

Because 39 1/2 divided by 1 1/4 is 31.6
Hope This Helps
Answer:
31.6
Step-by-step explanation:
Alright lets take a deep look at the question. It is asking for the miles/gallon, or miles per gallon so we already have our format set. Now for the important information, how do we find unit rate?
Simply put, we divide the unit numerator by the quantity in the denominator. Alright, so we have 39.5/1.25 already, which gives us a highway to our answer through dividing the numbers as they are shown.
Therefore, our unit rate is 31.6 miles per every gallon of fuel.

Answer:
Step-by-step explanation:
Find x in the diagram below.
Answer:
20°
Step-by-step explanation:
1) Opposite angles are equal, so the opposite will be 140°.
2) Then, you do 140+110+90+90 (since A and D are at right angles) which gets you 430°
3) Finally, since its a pentagon, you do 540° - 430° which is 110°

A trapezoid’s longer base is three times the length of its shorter base. If the trapezoid has an area of 32 square feet and a height of 4 feet, what is the length of each base?
Answer:
longer base: 10 2/3
shorter base: 5 1/3
Step-by-step explanation:
you first take 32 divided by 4 and then multiply that by 2 and you get 16 and then you divide that by 3 and you get 5 1/3 but then the longer one is 5 1/3 plus 5 1/3 (i hope that makes sense)
The grid contains a circle with a diameter of 2 centimeters. Use the grid to estimate the area of the circle to the nearest whole square centimeter.
A circle graphed on a 4-by-4 grid. The circle has a diameter of 4 units.
area: about ?? cm²
How can you change the grid to improve your estimate? Explain.
The area of the circle is the amount of space on the circle
The area of the circle is about 14 cm²
How to estimate the area of the circle?From the question, we understand that the circle fits perfectly into the grid.
This means that the area of the circle is about the same with the area of the square grid.
The area of the square grid is:
Area = 4 * 4
Evaluate
Area = 16
The surrounding areas are triangles with the following estimated dimensions:
Base = 1.5, Height = 1.5
The area of the four triangles is:
Area = 4 * 0.5 * 1.5 * 1.5
This gives
Area = 4.5
Subtract the area of the triangle from the square
Remaining area = 16 - 4.5
Remaining area = 11.5
Approximate
Remaining area = 12
Hence, the area of the circle is about 12 cm²
How to improve the grid?To improve the grid, we simply get the actual dimension of the black region

Lidia keeps eight cards with the picture of a tomato and four cards with the picture of a carrot on a table face down, so the pictures are hidden. She mixes up the cards then turns over one card and finds the picture of a carrot on it. She removes this card from the table and turns over another card.
What is the probability that the card Lidia turns over has a carrot on it?
A. 3/12
B. 3/11
C. 7/12
D. 7/11
I need help
Answer:
B
Step-by-step explanation:
Add the number of the remaining cards
8 cards of tomatoes + 3 remaining cards of carrots
since Lidia turned the cards and put away 1 carrot card.
At first she had 4 on the table but now she has 3
So, add 8+3= 11
The question is asking... what is the probability that the card Lydia turns over has a carrot on it.
so we put the number of remaining carrot cards over the total number of cards.
