A wheel has a circumference of 7 5/6 feet .How many times dies it turn in 423 feet

Answers

Answer 1

Answer: Circumference of the wheel is the outer part of the wheel. We know that the wheel is turning "x" times over 423 feet. What we're trying to find is how many turns occur over 423 feet.

What we got to find is the length of the wheel. Wait! They give it to us; the circumference is the length.

The wheel is traveling that length "x" amount of times for 423 feet. So, we have
7 5/6 × x = 423.

Divide to get x by itself and you get 54. The wheel spun 54 times. Any questions then leave a comment. Good luck!

Choose the graph of 3x + y = –2.

For the function y = x + 4, what is the output value if 3 is the input value?y = 1
y = 7
y = 12
y = 34

Answers

y = 7 is the output value for the given function y = x+4.

What is a function?

It is an expression, rule, or law that defines a relationship between one independent variable and dependent variable.

Given function is

y = x+4

where y is the output value and x is the input value of the given function.

If x= 3 then y is given by

y = 3+4 = 7

Hence, for the given function y = x+4 the value of y is 7 when x is 3.

CANT GET WRONGJason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months. Find the rate of change in the miles per hour that Jason bikes. A) .5 mile per hour per month B) 1 mile per hour per month C) 2 miles per hour per month D) 3 miles per hour per month

Answers

Answer: The correct option is (B) 1 mile per hour per month.

Step-by-step explanation: Given that Jason is training for a marathon bike ride. His average speed increased from 3 miles per hour to 6 miles per hour in 3 months.

We are to find the rate of change in the miles per hour that Jason bikes.

We know that

the average rate of change between the points (a, b) and (c, d) is given by

$A_r=(d-b)/(c-a).$

Since the number of months vary from 0 to 3, and the speed increases from 3 miles per hour to 6 miles per hour,

so the two points on the co-ordinate plane with number of months plotted across X-axis and average speed plotted on Y-axis are (0, 3) and (3, 6).

Therefore, the average rate of change in the miles per hour that Jason bikes is

$A_r=(6-3)/(3-1)=(3)/(3)=1.$

Thus, the required rate of change is 1 mile per hour per month.

Option (B) is correct.

B.... 6-3=3miles in 3 months .. and that's a mile per month

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of? 8 in3
24 in3
48 in3
72 in3

Answers

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = $(1)/(3)\pi r^(2) h$ --1

Volume of cylinder = $\pi r^(2) h$ --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

$\text{Volume of cone}= (1)/(3) \text{Volume of cylinder}$

Since we are given the volume of cone is 24 cubic inches .

So, $24= (1)/(3) \text{Volume of cylinder}$

$24 * 3= \text{Volume of cylinder}$

$72= \text{Volume of cylinder}$

Hence the volume of cylinder is 72 cubic inches

Option D is correct.

The correct answer is letter D. 72 in3

According to the Fundamental Theorem of Algebra, how many roots exist for the polynomial function?(9x + 7)(4x + 1)(3x + 4) = 0

Answers

Answer:

Three roots exist of given polynomial.

Step-by-step explanation:

Given: $(9x+7)(4x+1)(3x+4)=0$

Fundamental theorem of algebra: It states that each factor of polynomial with complex coefficient must be atleast one complex root.

If polynomial with real coefficients then their complex root with zero imaginary part.

In the given polynomial, $(9x+7)(4x+1)(3x+4)=0$

Each term as factor factor. Here we have total three factor. If we set each factor to 0 and solve for x. We will get root for each value of x.

So, Here should be three roots possible.

$9x+7=0\Rightarrow x=-(7)/(9)$

$4x+1=0\Rightarrow x=-(1)/(4)$

$3x+4=0\Rightarrow x=-(4)/(3)$

All roots are real.

Hence, Three roots exist of given polynomial.

IF JOHN RAN A 5-KILOMETER MARATHON HOW LONG WAS THAT IN METERS?

Answers

A kilometer is composed of 1000 meters. The term "kilo" means "a thousand."

So 5 kilometers means 5 1000 meters, thus it is equal to 5,000 meters.

1 km = 1000 meters

5 km * 1000 m / km = 5 * 1000 m = 5,000 meters

1 m = 0.001 km

5 km * 1m/0.001km = 5 m / 0.001 = 5,000 meters
