−12.7=y−3.4
Can you guys please help me solve this. Thanks!

Answers

For this case we have the following equation:
[tex]-12.7 = y-3.4 [/tex]
From here, we must clear the value of y.
For this, we follow the following steps:

1) we add 3.4 on both sides of the equation:
[tex]-12.7 + 3.4 = y-3.4 + 3.4 [/tex]

2) We rewrite the right side of the equation:
[tex]-12.7 + 3.4 = y + 0 -12.7 + 3.4 = y[/tex]

3) We do the algebraic sum of the left side of the equation:
[tex]-12.7 + 3.4 = y -9.3 = y[/tex]

Therefore, the solution of the equation is:
[tex]y = -9.3 [/tex]

Answer:
y = -9.3

fitness center currently has 320 members. Monthly membership fees are $45. The manager of the fitness center has determined that each time the membership fees increase by $5, approximately 10 members leave and go to a different gym.
Write an equation that can be used to find the revenue of the fitness center in dollars, y, after x price increases of $5.

y = -50x2 + 1,150x + 14,400

y = -50x2 + 3,425x + 14,400

y = -50x2 + 2,975x + 14,400

y = -50x2 + 2,050x + 14,400

Answers

y = -50x2 + 1,150x + 14,400 - This one seems to be the closest to the answer

Answer:

y= -50x^2+1,150x+14,400

Step-by-step explanation:

LEt x be the number of price increases of $5

y is the revenue

Revenue= membership fee * members

for x number of increase in fee by 5 then member ship fee becomes 45+5x

approximately 10 members leave, so members becomes (320-10x)

y = (45+5x) (320-10x)

Multiply it using FOIL method

y=45 * 320 +45*(-10x) + 5x * 320 + 5x * (-10x)

y=14400 - 450x + 1600x - 50x^2

Combine like terms

y= -50x^2+1150x+14400

Rewrite 20/6 as a mixed number.

Answers

Divide the numerator by the denominator and remove the remainder or following decimal.

20/6 = 3 R2 = 3

Thus, 3 is our whole number that resides next to the fraction.

Now take this number, multiply it by the denominator, and subtract this value from the numerator: 20 - 3(6) = 2. This is the numerator of the fraction in our mixed number.

Now simply add the denominator under this new numerator and place the three next to this fraction: 3 2/6.

The improper fraction number 20/6 is converted into a mixed fraction number as 3 ¹/₃.

What is the mixed fraction number?

The mixed fraction number is the combination of the whole number and the proper fraction number. In a proper fraction number, the numerator is smaller than the denominator.

The improper fraction is 20/6.

Convert the improper fraction into a fraction number.

⇒ 20 / 6

⇒ 10 / 3

⇒ (9 + 1) / 1

A shop sells three types of boots (football, rugby and hiking). Sales are usually in the ratio 6 : 2 : 3 last month, 24 pairs of football boots were sold. How many boots altogether were sold last month?

Answers

There were 44 boots sold last month

Answer:

Total number of boots sold = 44

Step-by-step explanation:

Ratio of football, rugby and hiking boots sold = 6 : 2 : 3

24 pairs of football boots were sold.

That is

6 n = 24

n = 4.

Number of rugby boots sold = 2 n = 2 x 4 = 8

Number of hiking boots sold = 3 n = 3 x 4 = 12

Total number of boots sold = 6n + 2n + 3n = 11n = 11 x 4 = 44

Total number of boots sold = 44

An hourglass consists of two sets of congruent composite figures on either end. Each composite figure is made up of a cone and a cylinder, as shown below:

Hourglass with sand measuring 47 millimeters high

© 2011 Jupiterimages Corporation

Each cone of the hourglass has a height of 12 millimeters. The total height of the sand within the top portion of the hourglass is 47 millimeters. The radius of both the cylinder and cone is 4 millimeters. Sand drips from the top of the hourglass to the bottom at a rate of 10π cubic millimeters per second. How many seconds will it take until all of the sand has dripped to the bottom of the hourglass?
A(6.4)
B(62.4)
C(8.5)
D(56.0)

Answers

The volume of a cylinder is given by the formula V=πr²h². In this instance, r is 4 and the height is 47-12 (the height of the cone at the bottom is 12 mm and the sand goes up to 47 mm on the top portion of the hourglass, including both the cone and cylinder) or 35 mm.
V=π(4²)(35)=560π mm³.
The volume of a cone is given by the formula V=1/3πr²h². In this instance, r is 4 and the height is 12 mm.
V=1/3π(4²)(12)=π(1/3)(12)(4²)=π(4)(4²)=64π mm³.
This gives a total volume of 560π+64π=624π mm³ of sand.
Since the sand goes down to the bottom at a rate of 10π mm³/second, it will take 624π/10π=62.4 seconds for the sand to all drain out.

Answer:

62.4

Step-by-step explanation:

factor the trinomial x^2+6x-16

Answers

For quadratics with an a value (coefficient of x²) of 1, we find factors of c, the constant, that sum to b, the coefficient of x. In our case we want factors of -16 that sum to 6.
-16 = -1(16) or 16(-1)
-16 = -2(8) or 8(-2)
-16 = -4(4) or 4(-4)

Out of these 6 possibilities, the only one that sums to 6 is 8(-2), because 8+(-2)=6.

This gives us the factors (x+8)(x-2).

Joseph squares a number and subtracts 8 from the answer. He then divides this result by 7. Finally he adds 12 and the result is now 20. What was Joseph's original number?

Answers

Let the number be X, then we find
[tex]( {x}^{2} - 8) \div 7 + 12 = 20[/tex]
[tex]( {x}^{2} - 8) \div 7 = 8[/tex]
[tex]( {x}^{2} - 8) = 56[/tex]
[tex] {x}^{2} = 64[/tex]
[tex]x = \sqrt{64} \: \: \: \: \: x = - \sqrt{64} [/tex]
[tex]x = 8 \: \: \: \: \: x = - 8[/tex]

Final answer:

We use reverse operations to solve Joseph's equation and find that the original number could have been either 8 or -8.

Explanation:

The question asks us to determine Joseph's original number based on a series of mathematical operations. We can set up an equation to represent the problem statement: let x be the original number. The sequence of operations given is:

Square x and subtract 8.

Divide this result by 7.

Add 12 to the result from step 2.

The final result is 20.

Representing this mathematically: ((x2 - 8) / 7) + 12 = 20. To find x, we need to work backward through these operations:

Subtract 12 from both sides: ((x2 - 8) / 7) = 8.

Multiply both sides by 7: x2 - 8 = 56.

Add 8 to both sides: x2 = 64.

Take the square root of both sides: x = 8 or x = -8 (considering both positive and negative square roots).

Therefore, Joseph's original number could have been either 8 or -8.

If two sets are negatively correlated, as the values in one of the sets increase, the values in the other set tend to decrease.

This means that there is an inverse relationship between the two sets, such that when one variable increases, the other variable tends to decrease.
