Answer:

The band needs to sell 4 more items from their fundrasier than the chorus needs to sell for their fundraiser.

Step-by-step explanation:

First we have to see how far each of the groups are from completing their goal.

For chorus, we get 2620-1225=1395 dollars.

For band, we get 2400-1314=1086 dollars.

Now, we see how long it takes for them to get to their goals.

For chorus, we get 1395/25 = 55.8. because they can't sell 0.8 of a set of candles, it round up to 56 candles.

For band, we get 1086/18.25 ≈ 59.5. because they can't sell half of a 3 gallon tubs of caramel popcorn, they have to sell 60.

So, when both of the funraisers meet their goals, the band needs to sell 4 more items from their fundrasier than the chorus needs to sell for their fundraiser.

Answer:

Step-by-step explanation:

hello :

the area is : A=(b×h)/2   b=6     h=9

A= (6×9)/2 =27ft2

The formula for area of a triangle is 1/2(b x h).

First, we'll have to identify our base and height. Since the problem gives them to us, we can rewrite the formula as 1/2(6 x 9).

From there, we can solve by multiplying.

1/2(6 x 9)

1/2(54)

And finally, we can divide to find the area.

1/2(54)

27

Therefore the area of the triangle is 27 feet.

Step-by-step explanation:

6(4x+1) = 78

Distribute

24x+6 = 78

Subtract 6 from each side

24x +6-6 =78-6

24x = 72

Divide each side by 24

24x/24 = 72/24

x =3

Answer:

x = 3

Step-by-step explanation:

6 (4x + 1) = 78

4x + 1 = 78 ÷ 6

4x + 1 = 13

4x = 13 - 1

4x = 12

x = 3

Given:

Given that O is the center of the circle.

AB is tangent to the circle.

The measure of ∠AOB is 68° and we know that the tangent meets the circle at 90°

We need to determine the measure of ∠ABO.

Measure of ∠ABO:

The measure of ∠ABO can be determined using the triangle sum property.

Applying the property, we have;

[tex]\angle ABO+\angle BAO+\angle AOB=180^{\circ}[/tex]

Substituting the values, we get;

[tex]\angle ABO+90^{\circ}+68^{\circ}=180^{\circ}[/tex]

Adding the values, we have;

[tex]\angle ABO+158^{\circ}=180^{\circ}[/tex]

Subtracting both sides by 158, we get;

[tex]\angle ABO=22^{\circ}[/tex]

Thus, the measure of ∠ABO is 22°

Answer:

y= -1\2x-4

Step-by-step explanation:

y=mx+c

perpinicular means you flip the slop and change the sign so the slope(m) become -1\2

y=-1\2x+c

since he gives you (8,-8) meaning x=8 and y= -8

we substitute

-8=(-1\2 x 8) +c

now we isolate c

-8+4=c

c=-4

the equation will be

y= -1\2x-4

Answer:

Supplementary Angles, because according to definition: Supplementary angles are the pair of angles that add to 180º.

Answer:

adjacent, supplementary

Step-by-step explanation:

The angles have one common side but no common interior points, so they are adjacent angles.

Also, they form a linear pair whose measures has a sum of 180 degrees, so they are supplementary angles.

The probability that three randomly chosen students were all born on a Wednesday is 1/343.

In a week, there are seven days, one of which is a Wednesday. Therefore, the probability that any one person was born on a Wednesday is 1/7. Assuming each student's birthday is independent of the others, the individual probabilities of each student being born on a Wednesday are multiplied together to find the combined probability of three students all being born on a Wednesday.

Thus, the probability of all three students being born on a Wednesday is:(1/7) x (1/7) x (1/7) = 1/343

So, the correct answer is d. 1/343.

Answer:

14.1 in³

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³.  Here the radius (r) is half the diameter, that is, half of 3 inches, or 1.5 inches.

Thus, the volume of the ball / sphere is V = (4/3)π(1.5 inches)³.  Find (1.5 inches)³ on a calculator (it is 3.375 inches³).  Then multiply this result by (4/3)π:

V = (4π/3)(3.375 inches³) = 14.1 in³

Final answer:

To find the number of cubic units the tennis ball occupies, calculate its volume using the formula V = (4/3) * π * r^3, where r is the radius. The tennis ball occupies approximately 0.157 cubic feet of space.

Explanation:

To find the number of cubic units the tennis ball occupies, we need to calculate its volume. The volume of a sphere can be found using the formula V = (4/3) * π * r^3, where r is the radius. The diameter of the tennis ball is 3 inches, so the radius is half of that, or 1.5 inches. Converting to the nearest tenth, we have a radius of 1.5 inches = 0.15 feet.

Substituting this value into the volume formula, we get V = (4/3) * π * (0.15)^3 = (4/3) * π * 0.0375 = 0.157 cubic feet. Therefore, the tennis ball occupies approximately 0.157 cubic feet of space.

The equation for a vertical line passing through (-6,6) is x = -6. However, this line cannot be represented by a formula for a linear function in the form y = mx + b, as a vertical line has an undefined slope.

A vertical line in a coordinate plane, such as the one passing through point (-6,6), has an equation format of x = c where c represents a constant value. In this particular case, as the line passes through the x-coordinate of -6, the equation of the vertical line is x = -6.

As for creating a formula for a linear function whose graph is this given line, that is not possible. Linear functions can be represented by the slope-intercept form "y = mx + b" where m represents the slope and b is the y-intercept. However, a vertical line does not have a slope (it is considered undefined or infinite), and therefore can't be represented as a linear function in this form.
