One angle of a triangle measures 120°. The other two angles are in a ratio of 5:7. What are the measures of those two angles
Answers
7x= second angle measure
120°= third angle
Triangles equal 180°. Add the angles above to total 180°. Find x to find two two unknown angles.
5x + 7x + 120°= 180°
combine like values
12x + 120= 180
subtract 120 from both sides
12x= 60
divide both sides by 12

A 155 pound person burns about 500 calories per hour playing racquetball. one pound id equal to 3500.
Q- If the person were to rest 5 minutes for every 30 minutes of playing, how long would it take to burn 1 pound?
Answers
p= c/t
155lb=500cal/1h
1lb= 3500 cal
30-5 =25 min of workout 25/60= 5/12 hr
1/t=c/5/12
1 lb =3500 cal
500/1=c/5/12
c=208 cal
3500/t=208/(5/12)
3500/t=500
t= 7 min to burn 1 pound calorie
Answer:
[tex]8\frac{1}{6}[/tex] hours or 8 hours and 10 minutes.
Step-by-step explanation:
We have been given that a 155 pound person burns about 500 calories per hour playing racquetball. One pound is equal to 3500 calories.
Since the person burns 500 calories per hour, so time taken to burn 3500 calories would be:
[tex]\frac{3500\text{ cal}}{\frac{\text{500 cal}}{\text{Hour}}}[/tex]
[tex]\frac{3500\text{ cal}}{500}\times\frac{\text{Hour}}{\text{Cal}}=7\text{ Hour}[/tex]
Now, we will convert 7 hours to minutes.
1 hour equals 60 minutes.
7 hours = 7*60 minutes =420 minutes.
Since the person take a rest of 5 minutes for every 30 minutes of playing, so we will divide 420 by 30 to find the number of times the person rested to burn 3500 calories.
[tex]\frac{420}{30}=14[/tex]
Now, we will multiply 14 by 5 minutes to find minutes the person rested.
[tex]14\times 5\text{ minutes}=70\text{ minutes}[/tex]
Total number of minutes to burn 3500 calories: [tex]420\text{ minutes}+70\text{ minutes}=490\text{ minutes}[/tex]
[tex]\frac{490}{60}=\frac{49}{6}=8\frac{1}{6}[/tex]
Therefore, it will take 8 hours and 10 minutes to burn 1 pound.
Asta needs a spanner for a 5-8 inch nut on her camping stove.
The shop sells 12mm spanners, 14mm spanners and 16mm spanners.
Asta knows that 1 inch = 2.54cm
What is the best size spanner for asta to buy?
Answers
After conversion, a 5-8 inch nut would require a spanner size between 127mm to 203.2mm. Unfortunately, the available spanner sizes (12mm, 14mm, 16mm) are all too small.
Explanation:To find out which spanner Asta needs, we first need to convert the inch measurements to millimeters (mm), as the spanners are sold in mm. Asta's nut size is 5-8 inches. She knows one inch equals 2.54cm. To convert these to mm, we multiply the values by 10 as 1cm is equal to 10mm. So, 5 inches equals 127mm and 8 inches equals 203.2mm. Given the available sizes of spanners (12mm, 14mm, and 16mm), none of these would fit her nut, as they are all far too small.

The cross-section of the rectangular pyramid, obtained by slicing it parallel to the longer sides of the base and through the top vertex, forms a 9-12-15 right triangle. The area of the cross-section is 54 square inches (Option C).
The rectangular pyramid has a base with sides of 5 inches and 12 inches, and diagonals measuring 13 inches. The height of the pyramid is 9 inches.
The cross-section obtained by slicing the pyramid parallel to the longer sides of the base and passing through the top vertex will form a right triangle with legs of 9 inches and 12 inches, and a hypotenuse of 13 inches (as given by the diagonals).
This right triangle is a 3-4-5 right triangle scaled up by a factor of 3, making it a 9-12-15 right triangle. The area of a right triangle is given by [tex]\(\frac{1}{2} \times \text{base} \times \text{height}\).[/tex]
So, the area of the cross-section is [tex]\(\frac{1}{2} \times 12 \times 9 = 54\)[/tex] square inches.

Answers
Drew could have purchased 3 books at prices of $4, $8, and $12, or at prices of $8 each.
Explanation:The question states that Drew purchased 3 books, each with a different price, for a total of $24. The cost of each book is a multiple of 4. To find the possible prices of the 3 books, we need to find 3 multiples of 4 that add up to $24.
Let's start by listing the multiples of 4: 4, 8, 12, 16, 20, 24,...
We can see that the possible prices of the 3 books could be $4, $8, and $12. Another possibility is $8, $8, and $8. There may be other combinations as well, but these are the two most likely options.

Answers
s = unknown side length of the equilateral triangle
The formula to use is
s = (2/3)*sqrt(3)*h
which helps tie together the side length s and the height h
Plug in the given height h = 26 and we get...

s = (2/3)*sqrt(3)*26
s = 30.0222
That rounds to 30

The length of each side of the equilateral triangle is approximately 52 cm.
Explanation:An equilateral triangle has all sides equal in length. To find the length of each side, we can use the property that an equilateral triangle's height is equal to half the length of one of its sides.
Since the height is given as 26 cm, we can set up the equation:
26 cm = (side length)/2
Multiplying both sides by 2, we get:
52 cm = side length
Therefore, the length of each side of the equilateral triangle is approximately 52 cm.

Brian makes 8% commission on sales. Weekly says total 4580, what is his Commission
Answers
To find Brian's commission, multiply his weekly sales of $4,580 by his commission rate of 8%. His commission for the week would be $366.40.
Explanation:To calculate Brian's commission, we need to apply the commission rate to his total weekly sales. Since his commission rate is 8%, we can calculate the commission by multiplying his total sales (
$4,580) by 0.08.
The calculation would be as follows:
Commission = Total Sales x Commission Rate
Commission = $4,580 x 0.08
Commission = $366.40
Therefore, Brian will earn a commission of $366.40 on his weekly sales.
Find the sum of the absolute deviations of the following data set.

Answers
To find the sum of the absolute deviations, calculate the average of the data set and then subtract it from each value, taking the absolute value. Finally, sum up all the absolute deviations.
Explanation:To find the sum of the absolute deviations, we first need to find the average of the data set. The average is calculated by adding up all the numbers and then dividing by the total number of values. So, the average of the data set 8, 5, 15, 12, 10 is (8 + 5 + 15 + 12 + 10) / 5 = 50 / 5 = 10.
Next, we calculate the absolute deviation for each number by subtracting the average from each value and taking the absolute value. The absolute deviations for the given data set are: |8 - 10| = 2, |5 - 10| = 5, |15 - 10| = 5, |12 - 10| = 2, |10 - 10| = 0.
Finally, we sum up all the absolute deviations: 2 + 5 + 5 + 2 + 0 = 14. Therefore, the sum of the absolute deviations is 14. So the correct choice is 14.

Answers
Claire’s mother is 4 years more than twice Claire’s age = 2x + 4
The sum of their ages is 58 years:
x + 2x + 4 = 58
3x + 4 = 58
3x = 54
x = 18
Claire's age = 18
Claire’s mother = 2(18)+4 = 36 + 4 = 40
claire's mothers age = 2x+4 ( 4 more than twice claire's age)
sum is addition
x + 2x+4 = 58
add like terms ( x +2x = 3x)
3x +4 = 58
subtract 4 from each side:
3x = 54
divide both sides by 3
x = 54 /3
x = 18
Claire is 18 years old
Claire's mother is 2*18 = 36 +4 = 40 years old

Two ships leave port at 10 A.M. One travels at a bearing of 50° at 25 mph, and the other travels at a bearing of 120° at 20 mph. How far apart are the ships at noon? Round your answer to the nearest tenth.
Answers
The second ship travels (20 mi/n)*(2 h) = 40 mi.
The angle between their directions of travel is 120° -50° = 70°.
The law of cosines can be used to find the distance (d) between the ships.
d² = 50² + 40² - 2*50*40*cos(70°)
d² = 2500 +1600 -4000*cos(70°)
d² ≈ 2731.919
d ≈ √2731.919 ≈ 52.3 . . . . miles
At noon, the ships are about 52.3 miles apart.
