Find the missing angle.

Answers

Answer:

total angle of a triangle = 180°

other two angles = 85° , 65°

∴ the missing angle = 180 - ( 85 + 65 )

                                 = 180 - 150

                                 = 30

hope this answer helps you..

please mark as brainliest... thank you!

the missing angle is 30°. you add the other two and subtract it from 180° since a triangle is always 180°. hope this helps? can i please get brainliest?

Describe the angle relationship and solve for the x.

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

Answers

Answer:

Part A: 56

Part B: 43.9

Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean

Step-by-step explanation:

Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.

Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.

Part C: explanation in answer.

Lana has a memory box that measures 18 inches wide by 9 inches deep. The height is 1.5 feet what is the volume of the box. IN INCHES!!!!!!!

Answers

Answer:

2916

Step-by-step explanation:

1.5 feet is 1 foot 6 inches, or 18 inches

volume is height * length * width, so 18 * 9 * 18 = 2916

Answer:

2,916 inches

Step-by-step explanation:

The formula for volume is length x width x height.

So, you will have to start to identify each of these.

First, though, because of 1.5 being feet and not inches, you must convert.

1 foot = 12 inches, so 1/2 foot = 6 inches. Meaning, 12 + 6, which is 18 inches.

Now, you can solve: 18 x 18 x 9 = 2,916.

Answers

Answer:

I believe your answer would be

Step-by-step explanation:

Using that formula, we can substitute in the values we need that are given to us in the question:

h = 12

r = 4

Now we need to use the formula.

V = 1/3 (pi) (4²) (12)

First lets do the exponent.

4² = 16

V = 1/3 (pi) (16) (12)

Now lets do pi × 16.

pi × 16 = 50.2654824574.

Now we have:

V = 1/3 (50.2654824574) (12)

Multiply 50.2654824574 and 12.

50.2654824574 × 12 = 603.185789489

Now all we have:

V = 1/3 (603.185789489)

Multiply them.

V = 201.06192983

So, your answer is V ≈ 201.06192983, or 201.

Write a polynomial expression that has the following characteristics:

The polynomial expression is a binomial.
The polynomial expression has degree 4.
The leading coefficient is 7.

Answers

Answer:

7x^4+x^3 (or 7x^4 + some random term)

Step-by-step explanation:

Since the polynomial expression must be a binomial, it must have two terms.

Since the binomial must have a degree of 4, and the leading coefficient must be 7, then a possible binomail could be 7x^4+x^3 because you have two terms, 7x^4 and x^3 while the degree is 4 and the leading coefficient is 7.

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?

GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO

Answers

Answer: hope this helps ♡

Lily had 16 stamps and Mackenzie had 20 stamps.

Step-by-step explanation:

Lily gives 4 stamps to Mackenzie

(Mackenzie)     m + 4 = 2(L - 4)      (Lily)

Solve for Lily:

m + 4 = 2L - 8

m + 4 + 8 = 2L

(m + 12) ÷ 2 = 2L ÷ 2

(m + 12) ÷ 2 = L

L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)

Mackenzie gives 4 stamps to Lily

(Mackenzie)     m - 4 = L + 4      (Lily)

m - 4 = ((m + 12) ÷ 2) + 4

m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4

2m - 4 + 4 = (m + 12) + 4 + 4

2m - m = (m - m + 12) + 8

m = 12 + 8

m = 20 (we will substitute this value of m in the next equation)

L = (m + 12) ÷ 2

L = (20 + 12) ÷ 2

L = 32 ÷ 2

L = 16

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.

Answers

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

---------------------------

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is 0.3
