basically get a shape
eg we will work with triangles,, add angles to the inside,, ensuring they add up to 180 (because angles in a triangle add up to 180)
now that we have the angles,, extend each side with a line to show the exterior angles.
we know that angles on a line add up to 180,, so to find the external angle,, we can use our internal angle
you would use:
[ 180- internal angle]
do this for all external angles
add all your answers together,, should equal to 180
Grace was cutting out paper snowflakes for the upcoming
school dance. It will take her 20 minutes to make the large
snowflake. It takes her 5 minutes to make each of the
smaller snowflakes. Grace only has 60 minutes to work on
snowflakes before she goes to soccer practice.
Write and solve an inequality that represents n, the
number of smaller snowflakes Grace will have time to
finish. Show your work algebraically.
Answer:
12 small snowflakes
Step-by-step explanation:
if she only has 60 minutes to make them and each small snowflake takes 5 minutes, then we solve with the equation:
n = 60/5
*edit: i forgot how to write an equality lol, that isn't the answer
Answer:
12 small snowflakes
Step-by-step explanation:
Because the math equals out to that

Step-by-step explanation:
Answer:
41/15
Step-by-step explanation:
[tex]4\frac{1}{10}[/tex] ÷[tex]1\frac{1}{2}[/tex]
first convert mixed fraction into or improper fractions.
=4*10+1/10 ÷ 1*2+1/2
=41/10 ÷ 3/2
convert division sign to multiplication and do the reciprocal.
=41/10 * 2/3
=41*2/10*3
=82/30
=41/15

Answer:
Hello! answer: 96
Step-by-step explanation:
I will find the area of each face separately and add them up so... for the triangles those would both be 6. the rectangle on the bottom would be 28 and the rectangle standing up would be 21 now for the triangle on top that would be 35. now we would just add these up so...
6 + 6 + 28 + 21 + 35 = 96 Therefore the surface area is 96 Hope that helps!

Step-by-step explanation:
bank reduces the interest rate from 12% p.a. to 10% p.a to expand its business. By how much is the yearly interest on Rs. 8,400 decreased?
Answer:
$168
Step-by-step explanation:
yearly interest = principal x time x interest rate
interest when interest rate is 12% = 8400 x 0.12 = 1008
interest when interest rate is 10% = 8400 x 0.1 = 840
decrease in interest rate = 1008 - 840 = 168
The penguins currently living on an island are of two types, Chinstrap penguins and Gentoo penguins. The range of the heights of the Chinstrap penguins on the island is 13.2 centimeters, and the range of the heights of the Gentoo penguins on the island is 15.4 centimeters.
Which of the following statements individually provide(s) sufficient additional information to determine the range of the heights of all the penguins on the island?
Indicate all such statements.
A The tallest Gentoo penguin on the island is 5.8 centimeters taller than the tallest Chinstrap penguin on the island.
B The median height of the Gentoo penguins on the island is 1.1 centimeters greater than the median height of the Chinstrap penguins on the island.
C The average (arithmetic mean) height of the Gentoo penguins on the island is 4.6 centimeters greater than the average height of the Chinstrap penguins on the island.
Answer:
The answer is "Option A"
Step-by-step explanation:
Using the range difference to calculate the maximum and minimum value.
The range of the chinstrap penguins are:
[tex]R(c) = Max(c) - Min(c) = 13.2[/tex]
The range of the Gentoo penguins are:
[tex]R(g) = Max(g) - Min(g) = 15.4[/tex]
For point A:
[tex]Max(c) = x\\\\Max(g) = x + 5.8\\\\R(c) = x - Min(c) = 13.2 \to x = 13.2 + Min(c)\\\\R(g) = x + 5.8 - Min(g) = 15.4 \to x = 9.6 + Min(g)[/tex]
equate both of them
[tex]13.2 + Min(c) = 9.6 + Min(g)Min(g) - Min(c) = 3.6[/tex]
It indicates that Min(c) surpasses Min(g), whereas Max(g) exceeds Max (c).
Therefore, the Max is picked for g for all penguins and the minimum is picked for c.
Range of all penguins [tex]= Max(g) - Min(c) = x + 5.8 - x + 13.2 = 19[/tex]
Therefore, it will be determined as the option.
For point B:
In estimating the range the median height cannot help.
For point C:
In order to calculate the variety, the connection between both the mean height cannot be sued.

C(n) = = 12n + 65, where n is the number of people.
Answer:
The function is correct, I just don't see a question.
Step-by-step explanation: 6 21 6 10
C(n) = 12n + 65
I will make up a question. How much will it cost 4 people each to rent the cabin?
C(n) = (12n + 65) / n n = 4
= (12 × 4 + 65) / 4
= (48 + 65) / 4
= 113 / 4
= $28.25
If your question is differnt just substitute the number of people into the question and solve for C(n)

The area is 220 square yd.
The missing length is ___ yd
Given : Area of the parallelogram is 220 square yard
We know that :
⊕ Area of a parallelogram is given by : Base x Height
⇒ Base x Height = 220
Given : Height of the parallelogram = 11 yards
⇒ Base x 11 = 220
⇒ Base = 20 yards
⇒ Missing Length = 20 yards

A water tank is in the shape of a cylinder with a diameter of 20 feet and a height of 20 feet. The tank is 70% full. About how many gallons of water are in the tank?
Answer:
32901 gallons
Step-by-step explanation:
First, we find the volume of the cylindrical water tank when it is full.
The volume of a cylinder is given as:
V =
where r = radius and h = height of the cylinder
The diameter of the tank is 20 feet, hence, its radius is 10 feet.
Volume, V, is therefore:
V =
This is the volume of the tank, when it is full.
When it is 70% full, the volume will be:
1 cubic foot () is 7.48 gallons.
Therefore, the volume of the 70% full tank in gallons will be:
4398.23 * 7.48 = 32901.05 gallons ≅ 32901 gallons
The tank contains 32901 gallons of water.
Answer:
approximately 32,900 gallons
Step-by-step explanation:
volume water in tank
v = πr²h * .70
v = π * 10² * 20 * .70
v = 4,398.2297150257 ft³
1 ft³ = 7.48 gallons
gallons in tank
4,398.2297150257 * 7.48 = 32,898.7582683922
~ 32,900 gallons
Question 16 of 36
Solve 16x+8>12x+20
A.x>7
B.x<3
C.x<7
D.x>3
Answer:
X>3 which is B
Step-by-step explanation:
Answer:
D. x > 3
Step-by-step explanation:
We have:
16x + 8 > 12x + 20
We have to make x be alone on one side.
So first, we subtract both sides by 8:
16x > 12x + 12
Subtract 12x from both sides:
4x > 12
Divide both sides by 4:
x > 3

Kiera and her brother, Desmond, are making trail mix to bring on their family's camping trip. Kiera uses 2 cups of raisins and 5 cups of nuts in her trail mix. Desmond uses 3 cups of raisins and 6 cups of nuts in his trail mix. Whose trail mix has a lower ratio of raisins to nuts?
Answer:
Kiera has a lower ratio of raisins to nuts. (2:5)
Step-by-step explanation:
To find this, you would have to make the number of nuts the same in each to accurately compare them.
It starts with Kiera's 2 cups of raisins and 5 cups of nuts. So it will be 2:5 (raisins first then nuts.)
Desmond will be 3:6 (have to make it the same order, raisins and then nuts.)
So I multiplied both the 2 and the 5 in 2:5 by 6 first.
Then multiply both the 3 and 6 in 3:6 by 5 to make the number of nuts the same in both.
So Kiera will have 12:30 and Desmond will have 15:30.
Then you can conclude that Kiera has the lower ratio.

What is the volume of the square pyramid? Enter in the box ___m^3
Answer:
V = 400 m^3
Step-by-step explanation:
The volume of a square pyramid is
V = 1/3 Bh where B is the area of the base and h is the height
B = 10 *10 = 50
V = 1/3 (100)* 12
V = 400 m^3
Which two angles below are supplementary
Answer:
41° and 139°
45° and 145°
Step-by-step explanation:
Supplementary angles refers to two angles which measures up to 180°.
Therefore, it is safe to say that, angle in supplementary angles = 180°
23° and 147°
= 23° + 147°
= 170°
Not supplementary
41° and 139°
= 41° + 139°
= 180°
Supplementary angle
30° and 60°
= 30° + 60°
= 90°
Not supplementary angle
45° and 145°
= 45° + 145°
= 180°
Supplementary angle

Người ta dự định chuyển 78452 lít dầu từ kho A sang kho B Trong 4 ngày đầu mỗi ngày chuyển được 18214 lít dầu hỏi còn phải chuyển bao nhiêu lít dầu nữa
Answer:
5596 liters of oil still need to be transferred.
Step-by-step explanation:
Total oil = 78452 liters
oil transferred each day for 4 days = 18214 liters
The amount of oil transferred in 4 days = 4 x 18214 = 72856 liters
The mount of oil left in ware house A
= 78452 - 72856
= 5596 liters
