We can use an equation to map out and solve for each age.
Years gone by = x
12+x=2(2+x)
12+x=4+2x
x=8
12+8=20, 2+8 =10

joe spent $15. he bought 2 cans of oil. abouthow many gallons of gasoline did he buy
The expression that can be used to determine the total amount of Joe spent on gasoline and oil is 2.85g + 3.15c.
The number of gallons of gasoline he bought is 3.0 gallons.
How to find the expression to determine the total amount of gas bought?Joe bought g gallons of gasoline for 2.85 dollars per gallons and c cans of oil 3.15 dollars per can.
Therefore, the expression that can be used to determine the total amount of Joe spent on gasoline and oil is as follows:
total amount = 2.85g + 3.15c
where
g = number of gallons of gasolinec = cans of oilJoe spent 15 dollars . He bought 2 cans of oil . The amount of gallons of gasoline he bought can be calculated as follows:
15 = 2.85g + 2(3.15)
15 = 2.85g + 6.3
15 - 6.3 = 2.85g
8.7 = 2.85g
g = 8.7 / 2.85
g = 3.05263157895
Therefore,
g = 3.0 gallons of gasoline

1) The astronaut's sense of imbalance in a space flight is due to the rotation of a device in which he or she feels a fictitious gravity that mimics gravity. The the device rotates according to the mathematical equation: n =g^0.5/2πr^0.5 Where n is the rotational speed and is measured in rotations per second (s). (r) is the radius of the circulator and is measured in meters (m). (g) is a simulation of gravity. Calculate the rotation speed of a device, that has a radius of 1.7 meters and rotates to simulate the gravitational force which equals to: g = 9.8 m/s^2 with steps please
Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
[tex]n=\dfrac{g^{0.5}}{2\pi r^{0.5}}[/tex] ...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
[tex]n=\dfrac{(9.8)^{0.5}}{2\pi \times (1.7)^{0.5}}\\\\=0.38\ \text{rotations per second}[/tex]
Hence, the rotational speed is 0.38 rotation per second.
Find the length of the rectangle if the perimeter is 244 yards the length is 18 less than three times the width?
Answer:
The Length of rectangle is 87 yards.
Step-by-step explanation:
Let width = w
Length = 3w-18
Perimeter of rectangle = 244 yards
We need to find length of rectangle.
First we need to find value of w
The formula used will be: [tex]Perimeter=2(length+width)[/tex]
Putting values and finding w
[tex]Perimeter=2(length+width)\\244=2(3w-18+w)\\244=2(4w-18)\\244=8w-36\\244+36=8w\\8w=280\\w=\frac{280}{8}\\w=35[/tex]
So, w= 35
The width of rectangle w = 35 yards
The length of rectangle l = 3w-18 = 3(35)-18 = 105-18 = 87 yards.
So, the Length of rectangle is 87 yards.
A half game in football is 45 min. At one point, a half was extended so that it was 48 minutes 30 seconds long. By what percentage was the half extended? Round to the full percentage.
Answer:
8%
Step-by-step explanation:
Multiply the number 45 by at least 1 point 0 something and therefore. We can assume that a 5% increase is around 47 minutes and 15 seconds and a 10% increase is around 49 minutes and 30 seconds ranging for you to use from 6% to 9%. The exact answer for the increase is around 7.78%, for me, I would plug in the equation like 45*1.7 and 45*1.8 on the calculator for more accuracy since you would need to round to the full percentage if it's between 7.5% to the exact number, it would be fully rounded to 8% since you would need at least a 5 to round up.
Gemma wrote the equation for a linear relationship below. y = 3x + 5 If x equals 9, what is the value of y? y = _____
Answer:
y = 32
Step-by-step explanation:
y = 3x + 5
y = 3(9) + 5
y = 27 + 5
y = 32
Answer:
Step-by-step explanation:
You replace all the x's in the problem with 9.
3(9)+5
3(9)=27
27+5=32

Show all work to factor x4 – 17x2 + 16 completely.
Answer:
(x - 4)(x + 4)(x - 1)(x + 1)
Step-by-step explanation:
Given
[tex]x^{4}[/tex] - 17x² + 16
Use the substitution u = x², then
u² - 17u + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the u- term (- 17)
The factors are - 16 and - 1, then
u² - 17u + 16
= (u - 16)(u - 1) ← replace u by x²
= (x² - 16)(x² - 1) ← both factors are difference of squares
= (x - 4)(x + 4)(x - 1)(x + 1)
Answer: -18
Step-by-step explanation: x4-17x2+16= -18

At the end of Tabitha's shopping experience, her total cost was $120.70. If she bought the number of 32-ounce cartons of orange juice she needed from part b, what percent of the bill was spent on orange juice? Round your answer to the nearest percent.
Incomplete question. However, let's work it out using an assumed set of data.
Assuming the list and value of items totaling $120.70 is:
10 liters of liquid soap > $601 carton of strawberry juice > $1732-ounce of orange juice > $43.7Answer:
approximately 36%
Step-by-step explanation:
To find the percent of the bill spent on orange juice, we need to find the ratio of its cost to the total cost of Tabitha's shopping experience. We can use the basic formula:
[tex]\frac{item cost}{total cost} * 100[/tex]
[tex]\frac{43.7}{120.7} * 100=[/tex] 36%
In other words, the $43.7 she spent on orange juice made up 36% of the bill.
