Answer:
132 degrees
Step-by-step explanation:
This is because if you have a 90 degree angle than the angles connected to it will be equal
To solve this, first look at the information we're given. We know that the shape the missing angle is part of is a triangle, so therefore, the sum of the interior angles will always be 180 degrees. There is a right angle inside of the triangle. One of the exterior angles is 132 degrees.
The first thing we can see from this is that the two interior angles which are not right angles must add up to 90 degrees. Since the sum of all the interior angles is 180 degrees, and there is already a 90 degree angle, the other two must add up to 90 degrees.
The next step would then be to find the other interior angle which is not the missing angle. We can do this because of the exterior angle.
A straight line always has a measure of 180 degrees. In this case, we can see that the line the exterior angle is resting on is straight, and the exterior angle + the other interior angle = the line. Therefore, 132 + the other interior angle must equal 180 degrees.
Subtract 132 from both sides, and you get the other interior angle has a measure of 48 degrees.
Now, to take that and figure out the missing angle.
We know that the angle with a measure of 48 degrees and the missing angle must add up to 90 degrees, as stated above.
48 + missing angle = 90
Subtract 48 from both sides, and you get the measurement of the missing angle is 42 degrees.

Factors for 32: 1, 2, 4, 8, 16, 32
Looking at the factors, we can see that the largest factor 20 and 32 have in common is 4. The answer isn't 1 or 2 because we are looking for the greatest common factor. This means we are looking for the largest of the factors which they both share.
Factors of 45: 1 , 3 , 5 , 9 , 15 , and 45.
Factors of 75: 1 , 3 , 5 , 15 , 25 and 75
Looking at these factors, we can see that 15 is the largest factor that 45 and 75 both share. The answer is not 1, 3, or 5 because we are again looking for the GREATEST common factor.

Two friends shop for fresh fruit. Elena buys a watermelon for $6.35 and 3 pounds of cherries. Taniy buys a pineapple for $2.15 and 2 pounds of cherries. Use the variable p to
represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Elena spent.
Answers
The expression that represents how much more Elena spent is $3.2 + p
Step-by-step explanation:
The variable p represents the price, in dollars, per pound of cherries.
Elena buys a watermelon for $ 6.35 and 5 pounds of cherries. So, the price of the cherries bought by Elena will be = 5*p
Then the total amount spent by Elena during her purchase of fresh fruits is:
$6.35 + 5*p
On the other hand, Tania buys a pineapple for $ 3.15 and 4 pounds of cherries. So, the price of the cherries bought by Tania will be 4*p
Therefore, the total amount spent by Tania during her purchase of fresh fruits is:
$3.15 + 4*p
You want to determine an expression to represent how much more Elena spent. That is, you want to determine the difference between the money spent by Elena and the money spent by Tania, which represents how much more Elena spent:
Total amount spent by Elena on fresh fruits - Total amount spent by Tania on fresh fruits
$6.35 + 5*p - ($3.15 + 4*p)
Solving:
$6.35 + 5*p - $3.15 - 4*p
($6.35 - $3.15) + (5*p - 4*p)
$3.2 + p
The expression that represents how much more Elena spent is $3.2 + p

What type of graph is best to use to show changes over time? A. bar graph B. line graph C. histogram D. circle graph
(will give brainliest if correct)
Answers
Answer: B
The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Answer for number 6: $8.10
Step-by-step explanation:
First of all, you start by multiplying 1.59 by 5. $1.59 x 5 = $7.95. Now, all you have to do is add $7.95 and $3.98. $7.95 + $3.98 = $11.90. Now the last this to do is Subtract $11.90 from $20.00. $20.00 - $11.90 = $8.10. You will receive $8.10 if he gives the cashier a $20.00 dollar bill.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Answer:
1. The entire course is 160 meters :) 2. Her essay is 18 pages long.
Step-by-step explanation:
1. The first step is to divide 60 by 3. That makes 20. So 20 is 1/8 of the entire course. Then you multiply 20 by 8 and you have 160. That makes the whole course 160 meters long.
You use the same steps for 1. to solve this one too!
2. The first step is to divide 15 by 5. That makes 3. So, 3 is 1/6 of the essay. Then you multiply it by 6. That makes 18. There are 18 pages in the essay. Hope this helped.
Answer:
1. is 160 meters 2. 18 pages
Step-by-step explanation:
1. since 60 meters is 3/8 you divide 60 by 3 and get 20 meters next you multiply 20 by 8 and get 160 meters
2. 15 pages=5/6 so you divide 15 by 5 and get 3 next you multiply 3 by 6 which equals 18 pages
