Volume of a figure is the measurement of space occupied by the figure. The volume of the specified sphere is given by Option B: 267. 95 m³
What is the volume of sphere?If the given sphere is of radius r units, then its volume is given as:
[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3[/tex]
For the given sphere, its diameter is 8 units, thus, its radius is half of its diameter and thus, of 4 units.
Thus, volume of specified sphere is obtained as:
[tex]V= \dfrac{4}{3} \pi r^3 \: \rm unit^3\\\\V = \dfrac{4}{3} \pi (4)^3 =\dfrac{256}{3} \times 3.14 \approx 267.95 \: m^3[/tex]
Thus,
Volume of a figure is the measurement of space occupied by the figure. The volume of the specified sphere is given by Option B: 267. 95 m³

How much material, in square inches, is needed to make the flag? square inches If the material costs $0. 15 per square inch, how much will Marta spend on materials to make the flag? $.
The amount of material needed by Marta to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] square inch.
The total cost of making the flag is;
[tex]\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] dollar.
Given
Marta is making a flag with the given dimensions.
The perimeter of the flag is 100 inches.
Let us consider that the flag has a triangular shape.
Hero's formula;According to the Hero's formula;
The area of the triangle is given by;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where, s is the semi perimeter and a, b, and c are the sides of the triangle.
Semi perimeter s = P/2,
Since the perimeter of the flag is 100 inches.
[tex]\rm S=\dfrac{100}{2}\\\\S=50[/tex]
The dimensions of triangular shape are [tex]\rm d_1, d_2 \ and \ d_3[/tex].
Then,
The area of the triangular flag becomes;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
So the amount of material needed to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
Therefore,
The cost of material = C = $0.15 per square inch
So the total cost in making the flag will be;
[tex]\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].
Hence, The amount of material needed by Marta to make the flag is [tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

solve system of equations:
-8x - 10y = 10
3x + 2y = 12
Answer:
x=10
y = -9
Step-by-step explanation:
-8x - 10y = 10
3x + 2y = 12
Multiply the second equation by 5
5(3x + 2y) = 12*5
15x+10y = 60
Add this to the first equation to eliminate y
-8x - 10y = 10
15x+10y = 60
-----------------------
7x + 0y = 70
Divide by 7
7x/7 = 70/7
x = 10
Now find y
3x+2y = 12
3(10) +2y = 12
30 +2y =12
Subtract 30 from each side
2y = 12-30
2y = -18
Divide by 2
2y/2=-18/2
y = -9

Examine the diagram.
A triangle has angles 1, 2, 3. Angle 4 is an exterior angle to angle 3.
For the angles shown in the diagram, which statements are true? Select all that apply.
The sum of m∠3 and m∠4 is 180°.
The sum of the measures of the adjacent interior angle and one of the remote interior angles is equal to the measure of the exterior angle.
∠3 is supplementary to ∠1.
m∠4 = m∠1 + m∠2.
m∠1 + m∠2 + m∠3 = 180°
The statements that are true regarding the diagram given are:
m∠3 + m∠4 = 180° (angles on a straight line)m∠4 = m∠1 + m∠2 (external angle theorem)m∠1 + m∠2 + m∠3 = 180° (triangle sum theorem).What is the Triangle Sum Theorem?The triangle sum theorem states that all the three interior angles in a triangle have a sum of 180 degrees all together.
Thus, in the diagram given, the statements that are all true are:

On Monday a shop receives $60.30 by selling bottles of water at 45 cents each
How many bottles are sold?
Answer:
134 bottles
Step-by-step explanation:
For this, I set up a proportion :
60.30/x = 0.45/1
60.30(1) = 0.45x
60.30/0.45 = 0.45x/0.45
x = 134 :)
Answer:
134 bottles
Step-by-step explanation:
conversion of dollars to cent:
$1 equals to 100 cents.
$60.30 will be (60.30*100) cents → 6030 cents
Bottles sold: total money / each bottle cost.
→ 6030 / 45
→ 134
So 134 bottles are sold for 45 cents to earn $60.30 or 6030 cents.

Answer:16 square feet
Step-by-step explanation:
add the length of the top and the bottom face them multiply the sum of those two by the perpendicular height between them and the product is to be divided by 2 : ((a+b)h)/2)
Answer:
16 ft²
Step-by-step explanation:
First you'll find the area of the rectangle forming in the trapezoid:
3 x 4 = 12
Next, you'll think logically and understand that if BC is 3 feet, EF is also 3 feet. So, you'll subtract 5 - 3 = 2, so AE and FD is 1 foot.
So, you'll now multiply to find the area of the whole trapezoid:
4 x 1 = 4
So:
4 + 12 = 16
Find the values of x and y.
Answer:
Given, x,y and 40 are the angles of a triangle.
Therefore, x+y+40=180
x+y=140
The difference between the two angles x and y is 30.
Therefore, x−y=30 ....(2)
Add equations (1) and (2), we get
2x=170
⇒x=85
Substitute this value n equation (2), we get
85−y=30
⇒y=85-30
⇒y=55
Therefore, angles of a triangle are x=85, y=55 and 40.
Answer:
Step-by-step explanation:
for x :
180° - 40° = 140°
40° / 2 = 20°
x = 20°
for y :
20° + 90° = 110°
180° - 110° = 70°
x = 70°
Once a large pink ribbon, the sign of the fight against breast cancer, was erected out of pink post-it notes on a billboard. If the area of therectangular billboard covered by the ribbon was approximately 4200 square feet, and the width of the billboard was approximately 60 feet, what
was the height of this billboard?

Sam has a party with snacks. One bowl of snacks has a mixture of fish crackers. There are 15 pretzels, 3 orange, 5 yellow, and 7 green fish crackers in the bowl.
What percent of the fish crackers are yellow?
Explanation:
Ignore the 15 pretzels. We're only focusing on the fish crackers.
3 orange + 5 yellow + 7 green = 15 total fish crackers
Of that total, 5 are yellow.
So approximately 5/15 = 1/3 = 0.333 = 33.3% of the crackers are yellow.

Given triangle ABC is similar to triangle DEF, angle A measures 30 degrees, and angle F measures 50 degrees, what is the measure of angle B?
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees

which set of pairs represents a function? PLSS HURRY (100 POINTS)
Answer:
{(0, 0), (1, 2), (2, 4), (3, 4)}
Step-by-step explanation:
A set of ordered pairs that represent a function is one in which each different ordered pair has a unique x-coordinate (so no two different ordered pairs can have the same x -coordinate).
Therefore, {(0, 0), (1, 2), (2, 4), (3, 4)} is a function as each different ordered pair has a unique x-coordinate.
The other sets all have different ordered pairs that share the same x-coordinate and so these sets do not represent functions.
The vertical line test is also used to determine whether a graph represents a function. If the vertical line intersects the graph only once, then the curve represents a function. This test can be applied to ordered pairs, in that if two ordered pairs have the same x-coordinate but different y-coordinates, they will be on the same vertical line and therefore do not represent a function.
