Answer:
4
Step-by-step explanation:
If two variables are proportional then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.
The given equation is
[tex]s=4c[/tex] ...(ii)
where,
s = number of cups of seltzer.
c = cups of cranberry juice.
On comparing (i) and (ii), we get
Independent variable: [tex]x=c[/tex]
Dependent variable: [tex]y=s[/tex]
Constant of proportionality: [tex]k=4[/tex]
Therefore, the constant of proportionality is 4.
A right triangle has one leg with a length of 10 m and another left with a length of
12 m. What is the length of the third side of the triangle?
OA) 22 meters
OB) 15.6 meters
OC) 6.6 meters
D) 2 meters
Answer:
B) 15.6
Step-by-step explanation:
Pythagorean thm: [tex]a^{2} +b^{2} =c^{2} \\[/tex]
Substitute each of the lengths for the legs like so:
[tex]10^{2} +12^{2} = c^{2}[/tex]
then expand the exponent and you will get c= 15.62
The chorus needs to raise $2,620.00 for a trip to the state competition. They are selling sets of candles for $25.00 per set. They have already raised $1,225.00 from the fundraiser.
The band needs to raise $2,400.00 to pay for a trip to the state capital to participate in a parade. They are selling 3-gallon tubs of caramel popcorn for $18.25 each. They have already raised $1,314.00 from the fundraiser.
If both are going to meet their goals, from this point on the
needs to sell blank
more items from their fundraiser than the blank
needs to sell from their fundraiser.
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.
In the figure above, AB is tangent to the circle with center O
at point A.
if AOB has a measure of 68 degrees, what is the measure, in degrees,of ABO?
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°

whta is the area of a triangle with a base of 6 feet and a height of 9 feet?30 ft2,27 ft2,28 ft2,54 ft2
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.
Hope this helps! :)

Answer:
x=3
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

the area of a circle is 36 pie cm^2 what is the radius of the circle?
Answer:
6cm
Step-by-step explanation:
To break down the steps back to radius, the formula is placed reversely in [tex]\pi r^{2}[/tex]
Since 36 is without pie, square root is needed.
[tex]\sqrt{36}[/tex]=6
Therefore, 6 cm is the radius.
Answer:
Step-by-step explanation:
hello :
the area is : A=πr² r : the radius
36π = πr² means : r²=36 so : r= 6
Find the area of the shape shown below
Add the top and bottom together, divide by 2, then multiply by the height:
Area = (7.5 + 2.5)/2 x 2.5
Area = 10/2 x 2.5
Area = 5 x 2.5
Area = 12.5 square units.
Three students are chosen at random. Find the probability that all three were born on Wednesday
a. 3/365
b. 3/7
c. 1/21
d. 1/343
The probability that three randomly chosen students were all born on a Wednesday is 1/343.
Explanation: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.

Find the equation of the line that is perpendicular to y = 2x + 8 and passes though the point (8, –8).
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

Find an equation of the vertical line through (-6,6). If possible, write a formula for a linear function whose graph is the given line
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.
Explanation: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.

A tennis ball has a diameter of 3 inches to the nearest tenth find the number of cubic units the tennis ball occupies
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.
