Answers
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
b = 34 degrees
Step-by-step explanation:
*triangles have an interior angle of 180 degrees
to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:
⇒ 180 - (115 + 31)
solve:
⇒ 180 - 146 = 34
b = 34

I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000

Step-by-step explanation:
Test approved
The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given three data sets.
All the samples have 10 data points.
Number of data points = 10
Mean of sample 1 = 9.1
Mean of sample 2 = 9.4
Mean of sample 3 = 8.9
We can see that the mean of the three samples is so close to each other.
So the data is reliable.
Hence the option is A.

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many more girls than boys are there?
Answers
Answer: number of girls = 21 & number of boys = 15
21 - 15 = 6 ( the difference is 6 )
Step-by-step explanation:
Answer:
add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

if $20.00 is for 12.25kg of peas ...what weight of peas can i get for $4.00
Answers
2.45kg
First you calculate the price per kg as follows:
If it’s $20 for 12.25 kg, the price per kg is $20/12.25=$1.63 per kg
If you have $4, you can figure out what weight you can get by taking $4/the price per kg, so $4/$1.63, which is 2.45 kg.
What is the greater faction than 11/20
Answers
Answer:
Are you looking to calculate whether 2/10 is greater than 11/20? One of the most common calculations you'll make in math is to compare fractions. In this really simple guide, we'll teach you how to compare and determine if 2/10 is bigger than 11/20 and walk you through the step-by-process of how the calculation is made.
As we always do in these tutorials, let's recap and remind ourselves that the number above the fraction line is called the numerator and the number below the fraction line is called the denominator.
Depending on the math problem you want to solve, there are two methods to calculate if 2/10 is larger than 11/20:
Convert the fractions to have the same denominator
Convert the fractions to a decimal number
Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 2/10 and 11/20 side by side so they are easier to see:
Converting Denominator
2
10
&
11
20
Our denominators are 10 and 20. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 10 and 20. In this case, the lowest common denominator is 20.
If we multiply the first denominator (10) by 2 we will get 20. If we multiply the second denominator (20) by 1 we will also get 20. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
2 x 2
10 x 2
11 x 1
20 x 1
This is what 2/10 and 11/20 looks like with the same denominator:
4
20
&
11
20
Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 4 is NOT greater than 11 which also means that 2/10 is NOT greater than 11/20.
Converting to Decimal
You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:
2/10 = 0.2
11/20 = 0.55
Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.2 is NOT greater than 0.55 which also means that 2/10 is NOT greater than 11/20.
Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!
