Answer:

4007400000

You move the decimal place to the right 9 places.

Step-by-step explanation:

The required distance around the earth (circumference) in standard form is 40,074,000,000.

A number system is described as a procedure of organizing to express digits. It is the mathematical notation for representing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special exhibit of every digit and defines the arithmetic structure.

Here,
The number 4.0074 x 10¹⁰ means 4.0074 multiplied by 10 to the power of 10. To convert this number to standard form, we simply need to move the decimal point 10 places to the right.

So the answer in standard form is:

40,074,000,000

Thus, the required distance around the earth (circumference) in standard form is 40,074,000,000.

Step-by-step explanation:

Answer:

If you take 50 and multiply it by two, you get 100. But, in order to get the right number, you have to multiply 45 by two as well. 45 x 2 is 90. 90 out of 100 is 90 percent. So 90% is the answer

Step-by-step explanation:

Answer:

96% or .96

Step-by-step explanation:

48 divided nu 50 equals .96 which then equals to 96 percent.

Answer:

-10d-4

Step-by-step explanation:

Well, you're in luck because I LOVE distributive property!!!

-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!

Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!

Now you combine them: -8d-12+-2d+8

Combine like terms!

-10d-4 would be your answer.

Answer:

y = x + 1

Step-by-step explanation:

I HOPE IM NOT TOO LATE BUT basically first u use the points to find the slope:

[tex]\frac{3+1}{2+2} = \frac{4}{4} = 1[/tex]

so far then, u have y = x + b  (there's an invisible 1 in front of the x)

next, substitute in the values from one set of coordinates to solve for b. I picked the second one bc positive numbers are easier:

y = x + b

3 = 2 + b

3 - 2 = b

1 = b

put this into your equation, and u get y = x + 1

Answer:

500

Step-by-step explanation:

125x4=500

(125+125+125+125)  

Sorry if it's blurry, I can retake the picture

[tex]\color{plum}\tt\bold{(C) \: 500 \: mi}[/tex]

Scale of a map :

=> 1 inch = 125 miles

Distance between two cities in map = 4 inches

Actual distance between the two cities :

[tex] =\tt 125 \times 4[/tex]

[tex] =\color{plum}\tt 500 \: miles[/tex]

Thus, the actual distance between the two cities = 500 miles

Therefore, the correct option is (C) 500 mi

Answer:

-3 and 1

Step-by-step explanation:

The zeros of the given function are -3 and 1.

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

jk, but her cub takes 13 and the mama 4

Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.

The together rate is the sum of each separate rate.

In this problem, the rates are as follows:

Hence:

[tex]\frac{1}{x} + \frac{1}{x + 9} = \frac{1}{6}[/tex]

[tex]\frac{x + 9 + x}{x(x + 9)} = \frac{1}{6}[/tex]

[tex]x^2 + 9x - 12x - 54 = 0[/tex]

[tex]x^2 - 3x - 54 = 0[/tex]

Quadratic equation with coefficients [tex]a = 1, b = -3, c = -54[/tex], hence:

[tex]\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-54) = 225[/tex]

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{3 + \sqrt{225}}{2} = 9[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{3 - \sqrt{225}}{2} = -6[/tex]

It would take each bear 9 hours to open the car door alone.
