Answer:

[tex](d)[/tex] [tex]5^{8.13} = 5^{8} * 5^{\frac{1}{10}} * 5^{\frac{3}{100}}[/tex]

Step-by-step explanation:

Given

[tex]5^{8.13}[/tex]

Required

Select an equivalent expression

[tex]5^{8.13}[/tex]

Simplify the power

[tex]5^{8.13} = 5^{8 + 0.1 + 0.03}[/tex]

Apply law of indices:

[tex]5^{8.13} = 5^{8} * 5^{0.1} * 5^{0.03}[/tex]

Express decimal as fractions

[tex]5^{8.13} = 5^{8} * 5^{\frac{1}{10}} * 5^{\frac{3}{100}}[/tex]

Answer:

Common difference is 55

Step-by-step explanation:

C(m)=55m

Substitute m=1 to find the distance traveled by Mia in one hour

55m= 55(1)

= 55

Distance traveled in one hour is 55 miles. Substitute m=2 to find the distance traveled by Mia in 2 hours

55m=55(2)

= 110

Distance traveled in 2 hours is 110 miles. Substitute m=3 to find the distance traveled by Mia in 3 hours

55m=55(3)

= 165

Distance traveled in 3 hours is 165 miles. Substitute m=4 to find the distance traveled by Mia in 4 hours

55m=55(4)

=  220

Distance traveled in 4 hours is 220 miles. Then the common difference is

d=110-55=165-110=220-165=55

Answer:

y = -12x - 77

Step-by-step explanation:

The standard form of the equation is expressed as y = mx+b

m is the slope

Given the coordinate (-7, 7) and (-6, -5).

m = -5-7/-6+7

m = -12/1

m = -12

Get the intercept b

Substitute m= -12 and (-7 7) into y = mx+b

7 = -12(-7) + b

7 = 84 + b

b = 7 - 84

b = -77

Get the required equation

y = mx+b

y = -12x +(-77)

y = -12x - 77

This gives the required equation

Answer:

7

2n + 3n + 4n. = 63

9n = 63

n = 63/9

n = 7

hope it helps

Answer:

n=7

Step-by-step explanation:

add 2n+3n+4n, which gives 9n =63

Divide by 9 on both sides, 9n/9 =63/9

n=7

If you need to confirm that's the right answer, just plug 7 back as n

2(7)+3(7)+4(7)=63

14+21+28 =63

63=63

Answer:

[tex]M = 1.75[/tex] --- Movies

[tex]V = 5.5[/tex] --- Video games

Step-by-step explanation:

Represent the movies with M and the video games with V.

The first month, the expression is:

[tex]2M + 3V = 20[/tex]

The next month, the expression is:

[tex]6M + 5V = 38[/tex]

Required

Find M and V

We have:

[tex]2M + 3V = 20[/tex] --- (1)

[tex]6M + 5V = 38[/tex] --- (2)

Multiply (1) by 3.

3 * [tex]2M + 3V = 20[/tex]

[tex]6M + 9V = 60[/tex] --- (3)

Subtract (1) from (3)

[tex]6M + 9V = 60[/tex]

- [tex]6M + 5V = 38[/tex]

-------------------------

[tex]6M - 6M + 9V - 5V = 60 -38[/tex]

[tex]4V = 22[/tex]

Divide by 4

[tex]V = 5.5[/tex]

Substitute 5.5 for V in (1)

[tex]2M + 3V = 20[/tex]

[tex]2M + 3 * 5,5 = 20[/tex]

[tex]2M + 16.5= 20[/tex]

Subtract 16.5 from both sides

[tex]2M = 3.5[/tex]

Divide by 2

[tex]M = 1.75[/tex]

A watch seller gained 20% by selling a watch for 1260.If he had to gain 30%,at what price should have he sold it?

Dalton III

Answered December 12, 2020

I shall explain the solution to this problem using rudimentary concepts.

First, we need to determine the original price of the watch.

Convert the percentage profit to a decimal by dividing by 100. In this problem, the profit is 20%, so we would divide:

20100=0.2

Add 1 to the profit expressed as a decimal.

1+0.2=1.2

Divide the price after the profit has been added by the figure which we have calculated to find the price before the profit (we shall assume that the currency used in this problem is the pound sterling)

£12601.2=£1050

Now that we have determined the original price of the watch, we shall determine at what price should the seller sell this watch in order to obtain a 30% gain. The same formula is used for the first two steps.

Convert the intended percentage profit to a decimal by dividing by 100. In this problem, the intended profit is 30%, so we would divide:

30100=0.3

Add 1 to the intended profit expressed as a decimal.

1+0.3=1.3

Now, instead of dividing, we would want to multiply the original price with the figure 1.3

£1050⋅1.3=£1365

So, in order to gain a profit of 30%, the watch seller should sell the watch at a price of £1365

Step-by-step explanation:

Hello!

For this type of problem, it is very helpful to draw your problem out, but I'll attempt to explain it in words, feel free to draw it out if you are able to!

You'll be solving this problem using trigonometry, meaning that we'll be creating a triangle to represent this problem.

If you are standing approximately 400 feet above the ground, that means the vertical leg of the triangle will be the value 400.

We are also given that the Amway Center is approximately 15840 feet away, meaning that the leg on the bottom will be a value of 15840.

This triangle will also create a right angle at the intersection of the two legs mentioned above, meaning that right triangle trigonometry can be applied to this problem.

What trigonometry identity can be used to find the angle of depression when we are given the adjacent and opposite legs? (SOH-CAH-TOA)

We'll be using tangent.

[tex]tan(x)=\frac{15840}{400}[/tex]

Remember to set your calculator to the degrees mode and take the inverse tangent of the ratio.

[tex]x=88.553[/tex]

To convert from 15840 feet to miles, use the conversion 5280 feet to miles.

[tex]15840ft*\frac{1mi}{5280ft}=3mi[/tex]

Hope this helps!
