-7+ 5Y = -37 simplify your answer as much as possible

-7+ 5Y = -37 Simplify Your Answer As Much As Possible

Answers

Answer 1

Answer:

y = -6

Step-by-step explanation:

To simplify this equation as much as possible, we have to get the variable y by itself.

To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.

-7 + 7 + 5y = -37 + 7

The 7s cancel out on the left side because -7+7 = 0 and so we are left with,

5y = -30

Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.

5y/5 = -30/5

y = -6

A circle’s circumference is 600 m.
What is a good approximation of the circle’s area? 1. 300\ m^{2} 2. 3,000\ m^{2} 3. 30,000\ m^{2} 4. 300,000\ m^{2}

Answers

The area of the circle is approximately 30,000 \(m^{2}\)

The circumference of the circle is given as 600m.

And we know that circumference = \(2\pi r\) where r is the radius of the circle.

Therefore,

\(2\pi r = 600\)

\(r = \frac{600}{2\pi }\)

\(r = \frac{300}{\pi }\)

Now, we know that area of the circle = \(\pi r^{2}\)

Putting the value of r in this, we get

area = \(\pi (\frac{300}{\pi } )^{2}\)

area = \(\pi.\frac{300}{\pi } .\frac{300}{\pi }\)

Therefore, area of the circle = 28,647.889 \(m^{2}\)

Therefore, the correct answer is 30,000 \(m^{2}\)

Answer:

walnuts cost $2.50 per pound, chocolate chips cost $1.50 per pound

Step-by-step explanation:

let w be the cost of 1 pound of walnuts

and c be the cost of 1 pound of chocolate chips

then

2w + 12c = 23 → (1)

5w + 3c = 17 → (2)

multiplying (2) by - 4 and adding to (1) will eliminate c

- 20w - 12c = - 68 → (3)

add (1) and (3) term by term to eliminate c

(2w - 20w) + (12c - 12c) = 23 - 68

- 18w + 0 = - 45

- 18w = - 45 ( divide both sides by - 18 )

w = 2.5

substitute w = 2.5 into either of the 2 equations and solve for c

substituting into (1)

2(2.5) + 12c = 23

5 + 12c = 23 ( subtract 5 from both sides )

12c = 18 ( divide both sides by 12 )

c = 1.5

then

cost of 1 pound of walnuts is $2.50

cost of 1 pound of chocolate chips is $1.50

walnuts are 2.5 and chocolate chips are 1.5

the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)

Answers

Subtract 1/2 by F(x) then multiply by 12

Answer:

F(\(\frac{a}{2}\)) = \(\frac{24}{a} +\frac{1}{2}\\\)

Step-by-step explanation:

so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have \(\frac{12}{\frac{a}{2} }\), if you can't see that, its 12/a/2. In other words, this is 12 ÷ \(\frac{a}{2}\) , which you can also format as 12 ·\(\frac{2}{a}\), because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!

I’m happy to help!
For this problem, it is asking for a percentage error, which is basically how far off the student was from the true value. (But in percentages)
First, we need to find how far off the student was in millimeters, which is calculated by finding the difference between the guess and the true value:
13-12.5=0.5
So the student was 0.5 millimeters off of the total, from here, we can use this number to find our answer.
Percentages also have regular number counterparts. For example, 1 is 100%, because you have one whole thing. 0.5 is 50% because 0.5 is half of a whole number. .33 is 33% etc.
To calculate how far the guess was from the actual amount, we divide the difference (0.5) by the true value (12.5)
0.5/12.5=0.04
0.04 converted to a percentage is 4%. (You move the decimal two places to the left, or multiply by 100)
This works because you can calculate how much a value takes up of the total by dividing. For example, to find out how much 1 takes up of 4, you would calculate 1/4, which equals .25, or 25%, and we know this is true.
I hope this helps!

Young has $150.00 in a savings account that earns 5%
interest, compounded annually.
What will the balance be after 1 year?
Round to the nearest cent.
S

Answers

Answer:

$157.50

Step-by-step explanation:

The equation you use for compound interest is:

\(A = P(1 + \frac{r}{n})^{nt}\\\)

where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

So for this question,

150 is our initial balance = P

5% is our interest rate = r

n = 1 because the interest is compounded annually per 1 year so 1 per year

t = 1 because we are calculating the balance after 1 year

Now we can plug these in and solve for the final amount (A).

\(A = 150 ( 1 + \frac{0.05}{1})^{1 * 1}\)

remember that 5% is 5/100 so we put 0.05 for r

\(A = 150 (1.05)^{1}\)

A = 150 (1.05)

A = 157.5

Simple you earn 5% each yearn on your money so 10% of 150 is 15 split it in half to get 5% $7.50 add that to his original money then you got $157.50

how would you solve this problem
the ratio of *name*'s age to his brother's is 2:3. In ten years, the ratio would be 4:5. How old is *name* and his brother now and in 10 years?
also how would you solve it if the ratio changed to something different, ex: 1:3 to 3:5 in 10 years

Answers

Answer:

*name* is 10 years old now and brother is 15 years now

In 10 years they would be 20 and 25 respectively

Step-by-step explanation:

Let x = *name*'s age now

let y = brother's age now

The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3

That means x/y = 2/3

Cross multiply => 3x = 2y =>

3x - 2y = 0   [1]

10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5

So (x + 10)/(y+10 = 4/5

Cross-multiply

5(x + 10) = 4(y + 10)

5x + 50 = 4y + 40

Subtract 4y from both sides

5x + 50 -4y = 40

and subtract 50 from both sides:

5x - 4y = 40 - 50

5x -4y = -10  [2]

Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that

[1] x 2

=> 2(3x - 2y) = 2 x 0

=> 6x - 4y = 0  [3]

[3] - [2]

6x - 4y - (5x -4y) = 0 - (-10)

6x - 4y -5x + 4y = 10

x = 10

Using equation [1] we get

x/y = 2/3

=> 10/y = 2/3

10 x 3/2 = y

5 x 3 = y

y = 15

So their ages are 10 and 15 now.

In 10 years they would be 20 and 25

If the ratios change we would have a different set of equations to solve for

For example if the current ratio is 1/3

Then we would get x/y = 1/3

or 3x - y = 0  [4]

and if 10 years from now the ratio is 3/5 then

(x + 10)/(y + 10) = 3/5

=> 5(x+10) = 3(y + 10)

=> 5x + 50 = 3y + 30

=> 5x - 3y = -20  [5]

And we would solve these equations to get x and y in a similar mannter

FYI the answers would be
x = 5, y = 15

The diagonal of the square whose area is 32 square ft.is 8ft.

What is pythagoras theorem?

It says that in a right angled triangle the square of hypotenuse is the sum of the square of the base and the square of height.

How to calculate the length of diagonal?

Let the side of the square be x

So the area becomes \(x^{2}\)

\(x^{2}\)=32

x=4\(\sqrt{2}\) ft.

If we draw a diagonal in a square it forms a triangle in which we can easily apply the pythagoras theorem.

The length of the diagonal becomes

=\(\sqrt{(4\sqrt{2}) ^{2}+ (4\sqrt{2}) ^{2} }\)

=\(\sqrt{64}\)

=8

Hence the length of the diagonal will be 8 ft.

Answer:

for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2

getting -2x/-2=-22/-2 then you simplify that and get x=11

and for the second one x=-7. first, you have to add 10 to both sides

(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

A factory can package 8 cans of diced pineapple every 60 seconds. Predict how many cans will be produced during an 8-hour work shift. (60 s = 1 min, 60 min = 1 h)

Answers

Answer:

3840 cans will be produced in an 8-hour work shift.

Step-by-step explanation:

So a factory can package 8 cans of diced pineapple in 60 seconds NOT minutes. So 60 seconds=1 minute, and 60 minutes=1 hour. So first we have to multiply 8 times 60 which comes out to be 480, so 480 cans are produced in 1 hour, not 8. So if 480 cans are produced in 1 hour then just multiply 480 times 8, which comes out to be 3,840.

Hence your answer is 3,840.
