PLEASE HELP ME!!! there's an equation: y × 6 for y = 2/3. what the heck is the y?!​

Answer:

Well no cheating not from me

Step-by-step explanation:

If a number is decreased by 79%, we are left with 21%.

so let's devide by 21 to get down to 1%, then multiply by 100 to get to the origininal number:

13 / 21 * 100 = 61.9047619048

To the nearest tenth it's 61.9

Final answer:

To find the original number when decreased by 79% to result in 13, we solve the equation 0.21x = 13, which gives us 61.9047619. Rounding this to the nearest tenth gives us 61.9.

Explanation:

To find the original number, we need to translate the percentage decrease back into the original number. Here's the step-by-step calculation:

So the original number to the nearest tenth is 61.9.

Step-by-step explanation:

7/12 X 7

7/12 which is 7/12

do 7/12 times 7 which is 49/12

12 goes 4 times into 49 (up to 48)

there's one remaining

and its over 12

4 1/12

The blank is -8

Step-by-step explanation:

Let us revise some rules of indices:

∵ [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{5}[/tex] × [tex]4^{x}[/tex]

∵ All bases are equal

∴ Use the first and third rule above to find x

∵  [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{3+-6}[/tex]

∴  [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{-3}[/tex] ⇒ L.H.S

∵  [tex]4^{5}[/tex] × [tex]4^{x}[/tex] = [tex]4^{5+x}[/tex] ⇒ R.H.S

Equate L.H.S and R.H.S

∴  [tex]4^{-3}[/tex] =  [tex]4^{5+x}[/tex]

Equate the indices of the two sides

∴ -3 = 5 + x

- Subtract 5 from both sides

∴ -8 = x

∵ x represents the blank

∴ The blank = -8

The blank is -8

Four to the power of three times four to the power of negative six is equal to four to the power of five times four to the power of negative eight.

To solve for the missing exponent, we can use the following properties of exponents:

Multiplying exponents with the same base: When multiplying powers with the same base, we add their exponents.

Negative exponents: A number raised to a negative exponent is equal to its reciprocal raised to the positive exponent.

Applying these properties:

4^3 * 4^-6 = 4^(3 - 6) = 4^-3 (since 4^-6 = 1/4^6)

4^5 * 4^x = 4^(5 + x)

Setting these equal to find x:

4^-3 = 4^(5 + x)

Therefore, x = -3 - 5 = -8.

Answer:

[tex]68 \: {cm}^{2} [/tex]

Step-by-step explanation:

You can use 1 cm = 10 mm very well to help you with this.

The small two at the end of the unit (cm^2) refers, that the shape of an object is two dimensional. If we make 1 cm two dimensional by multiplying it with the original 1 cm, we get a total area of

[tex]1 \: {cm} \times 1 \: {cm} \: = 1 \: {cm}^{2} [/tex]

We have created an equation. Since we know 1 cm = 10 mm, we can replace the centimetres in the equation with the millimetres, like so:

[tex]10 \: mm \times 10 \: mm = 1 \: {cm}^{2} \\ 100 \: {mm}^{2} = 1 \: {cm}^{2} [/tex]

From there, its just a simple matter of calculation:

[tex]6800 \: {mm}^{2} \times \frac{1 \: {cm}^{2} }{100 \: {mm}^{2} } = 68 \: \: {cm}^{2} [/tex]

Answer:

£518

Step-by-step explanation:

Asking price = original cost × markup%

A = 280(1.85) = 518

Brian May needs to price his Antique Cherry Special guitar at £518. This price is determined by the original cost, £280, and a 85% markup, £238, on this cost.

Brian May needs to define a price for his signature Antique Cherry Special guitar that was costed at £280 and he wants an 85% markup on this cost. Markup is calculated by multiplying the cost by the markup percentage. In this case, the markup is £280 * 85/100 = £238. Therefore, to determine the final price Brian needs to add the original cost and the markup, which is £280 + £238 = £518. So the price Brian should ask for the guitar is £518.

Answer:

[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]

Step-by-step explanation:

We have the complex number relationship as:

E=IZ

Where E=(5+9i) and I=(8+7i)

We solve for Z to get;

Z=E/L

We then substitute the expressions to get:

[tex]Z = \frac{5 + 9i}{8 + 7i} [/tex]

We rationalize to get:

[tex]Z = \frac{5 + 9i}{8 + 7i} \times \frac{8 - 7i}{8 - 7i} [/tex]

We simplify to obtain:

[tex]Z = \frac{40 - 35i + 72i - 63}{ {8}^{2} + {7}^{2} } [/tex]

This gives

[tex]Z = \frac{37i - 23}{113 } [/tex]

Or

[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]

Kate and Will meet at 1 : 09 pm

Solution:

The distance between Quebec City and New York City is 520 miles.

At the point where Kate and Will meet, they would have traveled 520 miles.

Let "t" represent the time it takes Kate to travel a certain distance before they met.

[tex]Distance = speed \times time[/tex]

If Kate drives at 55 mph, the distance covered would be

[tex]Distance = 55 \times t = 55t[/tex]

If Will drives at 75 miles per hour, then the distance covered will be

[tex]Distance = 75 \times t = 75t[/tex]

Since the total distance covered is 520 miles

Which means,

[tex]55t + 75t = 520\\\\130t = 520\\\\t = \frac{520}{130}\\\\t = 4[/tex]

Given that in question,

If Kate leaves Quebec and will leaves New York at 9:09 a.m

4 hours after 9: 09 am, Kate and Will will meet

9: 09 am + 4 hours = 1: 09 pm

Thus they would meet at 1 : 09 pm

[tex]y=-2x+3[/tex]

Step-by-step explanation:

Given:

[tex]2y+4x=-8[/tex]        .Equation of line

can be written as

[tex]y=-2x-8[/tex]     ...which is in Slope intercept form

To Find:

Equation of line passing through ( -1, 5) and is parallel to the line 2y+4x=-8

Solution:

[tex]y=-2x-8[/tex] ...........Given

Comparing with,  

[tex]y=mx+c[/tex]    ....general form in slope intercept

Where m =slope  

We get

[tex]Slope = m = -2[/tex]

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (-1 , 5) will also have the slope = m = -2.

Now the equation of line in slope point form given by

[tex](y-y_{1})=m(x-x_{1})[/tex]

Substituting the points and so we will get the required equation of the line,

[tex](y-5)=-2(x-(-1))=-2(x+1)\\\\y-5=-2x-2\\y=-2x+3......Equation\ of\ line[/tex]

Therefore, equation of the line that passes through (-1,5) and is parallel to the line

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are given that this energy is measured in calories. When you exercise, you use up or burn calories.

The information shows about how many calories a 125-pound person burns each minute bowling.

We need to do it convert 2 hours to minutes which would be 120 minutes and setup a proportion.

The amount of calories burnt per minute  x (total amount of calories burnt)

1 minute  =  120 minutes

Multiply 120 x 3 = 360.

Hence, they would burn 360 calories doing 2 hours of bowling.

You can determine if a polygon is a convex, by which way the edges points out

Convex is when all the points are facing out, so a polygon is a convex if all the edges are pointing out.

Answer:

  No side of the polygon crosses any other, even when extended indefinitely.

Step-by-step explanation:

If no sides of the polygon cross each other, it is convex when it has no internal reflex angles (angles measuring more than 180°). If sides of the polygon cross each other, it is not convex.

Another way to describe a convex polygon is that extending any one side indefinitely will not cause it to cross any other side.
