2 5/6 years is how many months
Final Answer: 34 months
Steps/Reasons/Explanation:
Hey there! Each year is 12 months. We can see that 2 years is already given. 2 years × 12 months = 24 months.
For [tex]\frac{5}{6}[/tex] we will multiply it by two to find the remaining amount of months. [tex]\frac{5}{6}[/tex] × [tex]2[/tex] = [tex]\frac{10}{12}[/tex]. This means that there is an extra 10 months of a year remaining.
Now we have to add them up. 24 months + 10 months = 34 months.

Find the volume of a right circular cone that has a height of 17 m and a base with a circumference of 6.3 m.
Answer:
The volume of the right circular cone is approximately 17.9 m³
Step-by-step explanation:
The given parameters of the cone are;
Height = 17 m
Circumference of the base, C = 6.3 m
The circumference, C, of a circle is given by the formula, C = 2×π×r
Therefore, we have;
C = 6.3 m = 2×π×r
r = 6.3/(2 × π) ≈ 1.002676
The volume, V, of a cone is given by the following formula;
[tex]V = \dfrac{1}{3} \times \pi \times r^2 \times h[/tex]
Where;
r = The radius of the base ≈ 1.002676
h = The height of the cone = 17 m
[tex]V = \dfrac{1}{3} \times \pi \times 1.002676^2 \times 17[/tex]
V = 1/3 × π × (1.002676 m)² × 17 m ≈ 17.89776 m³ which by rounding up to one decimal place is 17.9 m³
The volume of the right circular cone, V ≈ 17.9 m³.

The constant of proportionality is 4.
What is constant of proportionality?The constant value of the ratio between two proportional quantities is the constant of proportionality. When either their ratio or their product gives a constant, two varying quantities are said to be in a relation of proportionality. The type of proportion between the two given quantities determines the value of the proportionality constant: Variation in both a direct and inverse manner.
given relation
x 1 2 3 4
y 4 8 12 16
the equation is
y = 4x
1 * 4 = 4
2 * 4 = 8
3 * 4 = 12
and so on...
Hence the constant is 4.

Unit 7 homework 1: Gina Wilson answer key

The values for x are:
question 15 ⇒x=8
question 16⇒x=19
question 17⇒x=14
Here you should apply your knowledge about regular polygons. The question asks the values of x that is a variable for some interior angles. Then, you will find x from the sum of interior angles of each regular polygon.
Sum of Interior Angles of Regular PolygonThere is a formula that relates number of sides polygon with its sum of interior angles. See below.
S=(n-2)*180°
S=sum of interior angles of regular polygon.
n=number of sides of regular polygon.
Exercise 15First, you should find the value for the sum of interior angles. Here, the regular polygon has 4 sides. Then,
S=(n-2)*180°
S=(4-2)*180°
S=2*180°=360°
Note that only 3 interior angles are shown in the figure. Nonetheless, the question gives an external angle (71°). Thus, the internal angle will be: 180-71=109°. This is because the interior and exterior angles are supplementary.
Next step, sum of interior angles for finding x
[tex]10x+6+13x-2+109+8x-1=360\\ \\ 31x=360-112\\ \\ 31x=248\\ \\ x=\frac{248}{31} =8[/tex]
x=8
Exercise 16
First, you should find the value for the sum of interior angles. Here, the regular polygon has 6 sides. Then,
S=(n-2)*180°
S=(6-2)*180°
S=4*180°=720°
Next step, sum of interior angles for finding x.
[tex]90+9x-19+7x+3+111+5x+8+128=720\\ \\ 21x=720-321\\ \\ 21x=399\\ \\ x=\frac{399}{21} =19[/tex]
x=19
Exercise 17
First, you should find the value for the sum of interior angles. Here, the regular polygon has 5 sides. Then,
S=(n-2)*180°
S=(5-2)*180°
S=3*180°=540°
The image of the question shows the sides are congruent, consequently, the angles are equal.
Next step, sum of interior angles for finding x.
[tex]9x-18+9x-18+9x-18+9x-18+9x-18=540\\ \\ 45x=540+90\\ \\ 45x=630\\ \\ x=\frac{630}{45} =14[/tex]
x=14

Given:
The function on the Input output table.
To find:
The range of the given function.
Solution:
We know that, range is the set of output values.
From the given table it is clear that, hours of training is the input variable and pay per month is the output value.
So, range of the given function is the set of pay per month.
Range = {1100, 1200, 1300, 1400, 1500, 1600, 1700}
Therefore, the correct option is A.

Karen purchased a prepaid phone card for $15. Long-distance calls cost 19 cents a minute using this card. Karen used her card only once to make a long-distance call. If the remaining credit on her card is $12.91, how many minutes did her call last?
Answer:
I am pretty sure the answer is 11 minutes and the cost was $2.09
Step-by-step explanation:
Ihope this helps you:)
Step-by-step explanation:
Ok so we start with $15 now the remaining amount is $12.91, so let's substract
15.00 - 12.91 = 2.09
Alright now I must work with this number, since every minute used on the call is 19 cents, i must divide 2.09 to see how many 19 cents fit into this number
2.09 / 0.19 = 11
So she lasted talking or in this call 11 minutes....
