Answer:
the answer is A. 6 1/3 feet
Step-by-step explanation:
There are 12 inches in a foot. 12 x6=72 r of 4
there are 12 inches in a foot 12÷4=3. 1/3 of a foot
6 + 1/3= 6 1/3
Estimate the area of tje fan if m
Answer:
Area of the given fan is 763.4 cm²
Step-by-step explanation:
Area of a sector in a circle = [tex]\frac{\theta}{360}(\pi r^2)[/tex]
Here, angle θ = Central angle subtended by the arc
r = Radius of the circle
Since, fan is in the form of a sector of a circle with radius = 27 cm
Measure of the central angle subtended by the arc FN = ∠FAN = 120°
Area of the fan = [tex]\frac{120}{360}(\pi )(27)^2[/tex]
= [tex]\frac{729\pi }{3}[/tex]
= 243π
= 763.407
≈ 763.4 cm²
Therefore, area of the given fan is 763.4 cm²

Answer:
Step-by-step explanation:
From the given table,
A. The unit rate for each car is,
Car A = [tex]\frac{416}{13}[/tex]
= 32 miles per gallon
Car B = [tex]\frac{544}{16}[/tex]
= 34 miles per gallon
Car C = [tex]\frac{665}{19}[/tex]
= 35 miles per gallon
Car D = [tex]\frac{775}{25}[/tex]
= 31 miles per gallon
B. From the derived values in A, the car that uses the least amount of gas is Car C.
C. Total distance covered = 496 miles x 4
= 1984 miles
The gallons of gas the Car A would need for the journey can be determined by;
Car A requires 1 gallon for 32 miles
So that for 1984 miles = [tex]\frac{1984}{32}[/tex]
= 62 gallons
Car A would need 62 gallons of gas to make the trip.
D. Amount spent on gas for Car A = $2.12 x 62
= $131.44
E. speed = [tex]\frac{distance}{time}[/tex]
⇒ time = [tex]\frac{distance}{speed}[/tex]
Given the for Car A, speed = 68 miles per hour.
time = [tex]\frac{1984}{68}[/tex]
= 29.1765
time = 29 hours
It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.

Omar rented a truck for one day. There was a base fee of $17.95, and there was an additional charge of 98 cents for each mile driven. Omar had to pay when he returned the truck. For how many mile did he drive the truck?
The given question is incomplete. The complete question is:
Omar rented a truck for one day. There was a base fee of $17.95, and there was an additional charge of 98 cents for each mile driven. Omar had to pay $23 when he returned the truck. For how many mile did he drive the truck?
Answer: Omar drove the truck for 5.15 miles
Step-by-step explanation:
Base fee = 17.95 $
Additional charge per mile = 98 cents = 0.98 $ ( 100cents = 1$)
Now Omar payed = 22 $
Let the miles he travelled = x
Now , [tex]17.95+0.98\times x=23[/tex]
Solvimg for x :
[tex]x=5.15miles[/tex]
Thus Omar drove the truck for 5.15 miles
A feeder at the zoo in shape of a cone has a radius of 3 inches. It holds about 113.04 cubic inches of food. Approximate its height to the nearest inch. Use 3.14 to approximate the value of pie.
Answer:
12 inches
Step-by-step explanation:
My restaurant budget should not go over $100. If I bought main dish for $50 and $12 for each pizza, how many pizza's can I buy?
inequality :
50 + 12x ≤ 100
How many pizza's can I buy?
Answer:
x = 25
Step-by-step explanation:
50 + 12x <_ 100
12x <_ 100 - 50
12x <_ 50
x <_ 50 / 12
x <_ 25
You can buy about 4 pizzas.
I didn't use the way that I probably should have but you can subtract 50 from 100 and then divide the 50 by 12 and you will get 4.1666667.
Which statement is true concerning the vertex and axis of symmetry of h(x)=−2x2+8x?
The vertex is at (0, 0) and the axis of symmetry is x = 2.
The vertex is at (0, 0) and the axis of symmetry is y= 2.
The vertex is at (2, 8) and the axis of symmetry is x = 2.
The vertex is at (2, 2) and the axis of symmetry is y = 2.
Answer:
C.) The vertex is at (2, 8) and the axis of symmetry is x = 2.
Step-by-step explanation:
I got a 100 on edge
The vertex is at (2,8) and the axis of symmetry is x = 2
What is vertex and axis of symmetry of a curve?The vertex of a curve is the point where the curve passes its axis of symmetry. While the axis of symmetry is the line that divides the curve into two equal halves.
Analysis:
if y = a[tex]x^{2}[/tex]+bx +c. then the axis of symmetry occurs at [tex]\frac{-b}{2a}[/tex] and the vertex occurs at [tex]\frac{-b}{2a}[/tex] and the value of y at [tex]\frac{-b}{2a}[/tex].
comparing the above with the equation h(x) = -2[tex]x^{2}[/tex]+8x
x coordinate for vertex = [tex]\frac{-8}{2 x -2}[/tex] = 2
y coordinate at x = 2
-2[tex](2)^{2}[/tex] + 8(2) = 8
vertex is at point (2,8)
axis of symmetry is the x coordinate of the vertex which is at x = 2
In conclusion, the axis of symmetry is at x = 2 and vertex at point (2,80 option c

Answer:
cosine of angle a = 8/17
Step-by-step explanation:
Hello there!
Remember these are the trigonometric ratios
SOC CAH TOA
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
And we are asked to find the Cosine of angle A
Remember cosine is adjacent over hypotenuse
Hypotenuse - The longest side
Adjacent - the side that's not the hypotenuse nor the opposite
The adjacent side length of angle A is equal to 8 and the hypotenuse is equal to 17
so the cosine of angle a = 8/17

A single number cube is rolled twice and the two numbers are added.
PART A:
How can you determine the total number of possible outcomes
Answer:
well if you where talking about the dice the awnser is 6 and if you are tlking about the shirts then you can do 3 times 3 i thik is the right awnser
Step-by-step explanation:
1. a dice is a cube a cube has 6 sides a single number dice is a dice that only has numbers that are by themselves so the awnser can only be on the dice 6 to 9 so now we know that it is 6 now 6 times 2 is 12 because it got rolled twice

Answer:
[tex]x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}[/tex]
Step-by-step explanation:
Quadratic formula: [tex]x=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex] when the equation is [tex]0=ax^2+bx+c[/tex]
The given equation is [tex]1=-2x+3x^2+1[/tex]. Let's first arrange this so its format looks like [tex]y=ax^2+bx+c[/tex]:
[tex]1=-2x+3x^2+1[/tex]
[tex]1=3x^2-2x+1[/tex]
Subtract 1 from both sides of the equation
[tex]1-1=3x^2-2x+1-1\\0=3x^2-2x+0[/tex]
Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:
[tex]x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}[/tex]

Answer: They need to complete 21 more jumps all together .
Step-by-step explanation: So 14+13=J
14+13=27
27=j
World record: 48; 48-27=21
They will have to jump 21 more times in a row .

if the diameter of a circle is 124 centimeters, then what is the radius.
Answer:
radius = 62 cm
Step-by-step explanation:
radius = diameter/2
radius = 124/2 = 62 cm
Answer:
the radius 62
Step-by-step explanation:
the radius is really just the diameter split in half.
So, 124/2 = 62
If the pointer in the figure is spun twice, find the probability that the pointer lands on green (G) both spins.
Answer:
25%
Step-by-step explanation:
The bottom left and top right are each a quarter of the circle and are thus 25% each. The slivers in the middle have to add up to 50% and are all evenly sized. That means that each sliver is 50/4 or 12.5%
Since there are two green slivers, we multiply 12.5% * 2 to get 25%.
