Looking at this picture, tell me what the measue of angles 6, 7 and 8
Answer:
Angle 2 = angle 6 = 180 - angle 5 = 180 - 75 = 105
Angle 8 - 180 - angle 6 = 180 - 105 = 75
Angle 7 = 180 - angle 8 = 180 - 75 = 105

Anyone have the answer for this, please
Answer:
130°
Step-by-step explanation:
∠AOB + ∠BOC + ∠COD = 180
Note ∠BOC = 90°
so 3x - 28 + 90 + 66 - x = 180
2x + 128 = 180
2x = 180 - 128 = 52
x = 52/2 = 26
Note ∠EOD = ∠BOA = 3x - 28 = 3*26 - 28 = 50
∠AOE + ∠EOD = 180°
so
∠AOE + 50 = 180
∠AOE = 180 - 50 = 130°
Find the volume of the sphere (will mark brainiest)
Answer:
(1/6)π = 0.524
Step-by-step explanation:
Volume of Sphere = [tex]\frac{4}{3} *\pi *r^{3}[/tex]
Volume of Sphere = [tex]\frac{4}{3} *\pi *0.5^{3}=\frac{1}{6} \pi[/tex]
Answer:
V = (1/6)π
Step-by-step explanation:
Use the sphere volume formula:
V = (4/3)(π)(r^3)
V = (4/3)(π)(1/2)^3
V = (4/3)(π)(1/8)
V = (4/24)π
V = (1/6)π

If 385 of the people are students, what
percentage of the people at the school
carnival are students?
Answer:
Please tell me the total of students?
Step-by-step explanation:
Answer:
70% of the people at the carnival are students.
Step-by-step explanation:
Since the total is 550:
To find the percentage, we need to divide the amount of students by the total:
385/550=0.7
Then multiply the quotient by 100 and you have the percentage!
0.7*100=70

Oscar wants to fill a box with sand. Each bag of sand has a volume of 36 inches cubed. The base
area of the box is 54 inches squared. The height of the box is 13 inches. What is the volume of
the box? Does he have enough sand? If not, how many more bags does he need?
What is the area of the box?
B * H = A
54 in² * 13 in = A
702 in³ = A
The area of the box is 702 in³
Does he have enough sand?
If not, how many more bags does he need?
I am not sure how many bags he does have, so I cannot answer these two questions. I can, however, tell you how many bags he will need.
702 in³ / 36 in³ = 19.5 bags
He most likely will not have half a bag, so he will need 20 bags in total.

A diver is standing on a platform 24 ft above a pool. He jumps from the platform with an initial
upward velocity of 8 ft/s. Using the formula, h(t) = -16t2 + vt + s, where h is his height
above the water, t is the time, v is his starting upward velocity, and s is his starting height.
A) After how long will the diver reach its maximum height?
B) What is the maximum height the diver will reach?
GIVEN ↷
h(t) = -16t² + vt + swhere,
h⤿ Height ⤏0
t ⤿ time⤏?
v⤿initial velocity⤏8ft/s
s⤿initial height⤏24ft
TO FIND ↷
The maximum heightTime taken to reach the maximum heightSOLUTION ↷
we know that,
-16t² + vt + s = h(t)-16t² + 8t + 24 = 0To factorise the equation, we'll divide the both side by 8 and multiply by -1
we get,
2t² -t -3 = 02t² +2t -3t -3 = 02t(t+1) -3(t+1) = 0(2t-3)(t +1) = 0so,
2t - 3 = 0
2t = 3
t = 3/2
t = 1.5 seconds
hence, the diver will take 1.5 seconds to reach the maximum height
Now , to find the maximum height ,
we'll insert the value of time taken in the given equation which is ↷
h(t) = -16t² + vt + sh(1.5) = -16(1.5)² + 8 x 1.5 + 24h(1.5) = -16 x 2.25 + 12 +24h(1.5) = -36 +12 +24h(1.5) = -36 +36h(1.5) = 0h = 0/ 1.5h = 0Hence , the maximum height the diver will reach in 1.5 seconds = 0

a regular hexagonal nut of side 1 cm and length 3 cm with a central hole of diameter 1 cm. 3 cm 1 cm 1 cm. Calculate the volume of metal in the nut. (Ignore the thread and give your answer correct to 3 significant figures.) (WAEC]
Answer:
5.44 cm³
Step-by-step explanation:
The volume of the hexagonal nut can be found by multiplying the area of the end face by the length of the nut. The end face area is the difference between the area of the hexagon and the area of the hole.
The area of a hexagon with side length s is given by ...
A = (3/2)√3·s²
For s=1 cm, the area is ...
A = (3/2)√3(1 cm)² = (3/2)√3 cm²
__
The area of a circle is given by ...
A = πr²
The radius of a circle with diameter 1 cm is 0.5 cm. Then the area of the hole is ...
A = π(0.5 cm)² = 0.25π cm²
__
The volume is the face area multiplied by the length, so is ...
V = Bh = ((3/2)√3 -0.25π)(3) . . . . . cm³
V = (9/2)√3 -0.75π cm³ ≈ 5.44 cm³
The volume of the metal is about 5.44 cm³.

Find the interquartile range of the following data set.
3, 9, 12, 4, 6, 40, 25, 14, 10
Help me please!!!!!!!
Answer:
56 cm²
Step-by-step explanation:
The area of the composite shape is the sum of the areas of the parts. In this case, that is the sum of the areas of the central rectangle and four (4) congruent triangles.
The rectangle has dimensions 11 cm × 4 cm, so its area is ...
A = LW = (11 cm)(4 cm) = 44 cm²
Each triangle has a base of 2 cm, and a height of 2+1 = 3 cm. The area of each triangle is ...
A = 1/2bh = 1/2(2 cm)(3 cm) = 3 cm³
The total area of the rectangle and 4 triangles is ...
area of the figure = (44 cm²) +4(3 cm²) = 56 cm²

Solve for x. Can you please help me?
Answer:
6√3
Step-by-step explanation:
Let's take the vertical side in the middle as y and the side on the left as z.
We have:
from the right triangle on the right:
9²+y²=x²
from the right triangle over the big triangle:
z²+x²=(9+3)²=12²
from the right triangle on the left:
3²+y²=z²
We can use substitution in our three equations to get x.
9²+y²=x²
z²+x²=12²
3²+y²=z²
First, solve for y² in terms of x². We want everything in terms of x so we can solve for it.
9²+y²=x²
subtract 9² from both sides
x²-81 = y²
plug that into the third equation
3²+(x²-81)=z²
x²-72=z²
z²+x²=144 (the second equation)
plug x²-72 for z²
x²-72+x² = 144
add 72 to both sides
2x² =216
divide both sides by 2 to isolate x²
x²=108
square root both sides to get x
x = √108 = 6√3
