How many revolution will a car wheel of diameter 30in make as the car travels a distance of one mile.

Answers

Answer 1

Answer: Circumference = (pi) x (diameter) = 30 pi inches.

1 foot = 12 inches
1 mile = 5,280 feet = 63,360 inches

Number of revolutions in 1 mile = (63,360) / (30 pi) = 672.27... revs (rounded)

Adam wants to buy a video game system that costs $100.00. He has $28.35 in one piggy bank and $31.90 in another piggy bank. How much more money does Adam need before he can buy the video game system? How can estimation be used to make sure the answer is reasonable? A. Answer: Adam needs $160.25 more. Estimation: $28 + $32 = $60. $100 + $60 = $160. Adam needs about $160 more to buy his video game system. B. Answer: Adam needs $39.75 more. Estimation: $28 + $32 = $60. $100 – $60 = $40. Adam needs about $40 more to buy his video game system. C. Answer: Adam needs $30.13 more. Estimation: $28 + $32 = $60. $60 ÷ 2 = $30. Adam needs about $30 more to buy his video game system.

Yes 127 131 128 133
No 73 69 72 66

A.
Yes, because the results from Survey 1 differ the most from the other surveys’ results.

B.
Yes, because the results from Survey 4 differ the most from the other surveys’ results.

C.
No, because the sampling methods are all different but have about the same results.

How do you solve a quadratic equation?

Answers

Oh that's easy, all you have to do is use the quadratic equation :)
ax^2+bx+c
A would be the number squared, b would be the number with just an x and c would be the single number :) Look at the attachment and you can see how to set it all up.
Hope this helps and could you mark me as the brainliest?

if in ax^2+bx+c=0 form then
use quadratic formula
x= $\frac{-b+ \sqrt{b^(2)-4ac} }{2a}$ or $\frac{-b- \sqrt{b^(2)-4ac} }{2a}$

input and subsitute and that is the answer

I’m dumb and need helpIs -2 a solution to x < -2? Is -2 a solution
to x < -2? Explain your answers.

Answers

Answer:

See below.

Step-by-step explanation:

x < -2 means that x is any number that is less than -2.

Is -2 less than -2? Answer: No.

A number is equal to itself. A number is not greater than itself or less than itself.

When the solution to an inequality is x < -2, the only values of x that are valid are numbers less than -2. -2 itself is not a valid solution.

Which are characteristics of the graph of the function f(x) = (x + 1)2 + 2? Check all that apply.A.The domain is all real numbers.
B.The range is all real numbers greater than or equal to 1.
C.The y-intercept is 3.
D.The graph of the function is 1 unit up and 2 units to the left Efrom the graph of y = x2.
F.The graph has two x-intercepts.

Answers

This is a polynomial function called Quadratic Function. This is written as:

$f(x)=(x+1)^2+2$

Recall that the graph of a quadratic function is a special type of U-shaped curve called parabola. The graph of this function is shown in the Figure below. From that, we can say the following:

A. The domain is all real numbers.

This is true. In fact, the domain of any polynomial function is the set of all real numbers.

B. The range is all real numbers greater than or equal to 1.

This is false. Instead, the range is all real numbers greater than or equal to 2, that is the $y-coordinate$ of the vertex.

C. The y-intercept is 3.

This is true. We can find the $y-intercept$ letting $x=0$ , so:

$x=0 \n \n y-intercept \rightarrow f(0)=(0+1)^2+2=3$

D. The graph of the function is 1 unit up and 2 units to the left from the graph of $y=x^2$

This is false. The correct statement is that the graph of the function is 2 units up and 1 unit to the left from the graph of $y=x^2$

E. The graph has two x-intercepts.

This is false. As shown the graph below, this function does not have any $x-intercept$
