Step-by-step explanation:
Answer:
2 × 3² × 5²
Step-by-step explanation:
450 ÷ 2 = 225
225 ÷ 3 = 75
75 ÷ 3 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1
450 = 2×3×3×5×5
450 = 2 × 3² × 5²

A bicycle tire has a diameter of 3 feet. How many turns of the wheel could it take for the bicycle to go 792 feet?
Answer:
84 complete turns
Step-by-step explanation:
In order to find the number of turns that the bicycle wheel is going to take while going 792 feet, we need to find the circumference of the wheel.
[tex]C = \pi \: d = 3.14 \times 3 = 9.42 \: ft \\ no \: of \: turns = \frac{792}{9.42} \\ = 84.0764331 \\ = 84 \: turns[/tex]
Shani sells televisions. The formula she uses to calculate her monthly income is A = 800 + 200t, where A equals her total monthly income
and equals the number of televisions she sells.
How much money did Shani earn if she sold 9 televisions?
А S800.00
в, $1,000,00
с. $1,800.00
D, $2,600,00
Е. $9,000.00
Answer:
D
Step-by-step explanation:
plug in 9 where ‘t’ is. the formula becomes
A= 800+ 200(9) multiply 9 x 200
A= 800 + 1,800 add
A= 2,600
Answer:
D
Step-by-step explanation:
800 is the base amount she is already given/has. Since it is 200t the t represents how many televisions she sells so by doing 800 + 200(9) you will get 2,600.00.

The area of a square is 102 square units. What is an
estimated value for the length of a side of the square?
between 10 and 11
between 11 and 12
between 12 and 13
between 13 and 14
Answer:
Between 10 and 11.
Step-by-step explanation:
To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)
10²= 100
11²= 121
Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.

4 ft)
The circumference of outer circle is about
____ ft greater than the circumference of the inner circle.
(Round to the nearest tenth as needed.)
HOW MANY FEET GREATER IS THE CIRCUMFERENCE OF THE OUTER CIRCLE THAN IT IS OF THE THE INNER CIRCLE *ROUND TO THE NEAREST TENTH*
answer fast please!
Answer:
25.1
Step-by-step explanation:
1. Find the radius of the inner circle
(the formula for the circumference of a circle is [tex]C=2\pi r[/tex])
To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:
[tex]22=2(\frac{22}{7} )r[/tex]
then solve for [tex]r[/tex]
[tex]r=3.5[/tex]
2. add [tex]4[/tex] to the radius of the inner circle
[tex]3.5+4=7.5[/tex]
3. find the circumference of the outer circle using [tex]7.5[/tex] as the radius
[tex]C=2(\frac{22}{7})7.5[/tex]
[tex]C=47.1[/tex]
4. Subtract the circumference of the inner circle from the circumference of the outer circle
[tex]47.1-22=25.1[/tex]
Plz help ASAP!! A surgical technique is performed on eight patients. You are told that there is an 80% chance of success. Find the probability that the surgery is successful for fewer than two patients. Please show your work. Hint: the answer is 0.000084.
Answer:
This is a fairly simple binomial distribution. We know it's binomial, because we're looking for a "fixed" number of patients, not the "first" like a geometric.
You can use your calculator:
binomcdf(n,p,Kr)
n=population, p=probability, Kr=number you're looking for
binomcdf(8,.8,1)
We have to do 1, not 2, because it says fewer than 2, which means 1.

Why was radian such a good safety on the football team? (25 pts)
Answer: because of the translational and rotational motion of the football
Step-by-step explanation:
A kick or a well thrown football follows a projectile path while spinning. In football, creedence is given to the translational motion which is independent of the spinning rotational motion. Radian is good in analysing the path because the angle representing one radian, is such that the length of the subtended circular arc is equal to the radius of the circle.

100 = 5 x
(4 + 2)
ANSWER: 100=5*6
100=30
HOPE IT HELPS!
Answer:
x = 3 1/3
Step-by-step explanation:
Let's go over the order of operations.
P: Parentheses
E: Exponents
M/D: Multiplication/division (in order of appearance)
A/S: Addition/Subtraction (in order of appearance)
100 = 5*(4 + 2)
Since there are values in parentheses, solve those first: 100 .= 5x(6).
Next, multiply 5x by 6. 100 = 30x.
Finally, divide each side by 30 to find the value of x. 3 1/3 = x
Therefore, the value of x is 3 1/3.
(Note: this is assuming the term "x" is a variable, and not the multiplication sign, *.)

Erin made a line plot of the amount of time she practiced shooting free throws each day in the past 10 days.
Line plot named as ALTDCTime Spent Practicing (hours)ALTDC shows a number line from one-fourth to two and one-fourth. The number line is divided into 8 equal parts. 1 dot on one-half, 2 dots on three-fourths, 3 dots on 1, 2 dots on one and one-fourths, 1 dot on one and half and 1 dot on 2 is given.
Part A
What is the difference between the greatest and least times Erin practiced shooting free throws?
A. 1 hour
B. 114hours
C. 112hours
D. 2 hours
Part B
What is the most common amount of time Erin practiced shooting free throws?
Enter your answer in the box.
hour(s)
Part C
Drag the numbers to write an equation for the total amount of time t Erin practiced shooting free throws in the 10 days.
Numbers may be used once, more than once, or not at all.
Part D
What is the total amount of time Erin practiced shooting free throws in the 10 days?
A. 11 hours B. 1112 hours C. 1134 hours D. 12 hours
Answer:
Data: for the 10 days of practice, we have:
0.5 hours 1 time.
0.75 hours 2 times
1 hour 3 times
1.25 hours 2 times
1.5 hours 1 time
2 hours 1 time.
A) the largest amount number of times that she practiced by the same amount of time is 3 (for the 1-hour practice)
The smallest is 1 ( for the 0.5h, 1.5h, and 2h practices)
the difference is 3 - 1 = 2.
B) the time that she practiced more times is 1 hour, she practiced that amount of time in 3 different days out of the 10 days.
C) the equation can be found by multiplying the number of hours by the number of times that she practiced that amount of time, and then adding all of them:
0.5h*1 + 0.75h*2 + 1h*3 + 1.25h*2 + 1.5h*1 + 2h*1
D) the solution for the previous equation is 11 hours. Here the correct option is A.
A train travels at 45 miles per hour. Write and equation that represents the distance, d, that the train will travel, in t hours.
Answer:
d = 45 * t
Step-by-step explanation:
We know the equation as dert
distance equals rate * time
d = 45 * t
Answer:
d = 45 * t
Step-by-step explanation:
Step 1: Ok so for a. we can just need to build a equation representing the space the practice travels in t hours:
We can also recognize that it travels 45 mph, in order that is representing by 45(t).
d is the distance. So the equation is d = 45(t)
Step 2: For phase b. we change 2.5 with t a the equation. Then we solve it
d = 45(2.5)
45 * 2.5 = 112.5

Answer:
A=14
Use formula A^2+B^2=C^2
Answer:
∠ A ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{MR}{AR}[/tex] = [tex]\frac{6}{15}[/tex] , thus
A = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 24° ( to the nearest degree )

Answer:
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
Step-by-step explanation:
We know that the given unit vector is in the direction of the x-axis.
Remember that an unit vector is a vector which magnitude is the unit, that's why is called like that.
So, the given unit vector can be written as [tex]v=1i+oj[/tex], where [tex]i[/tex] indicates the horziontal coordinate and [tex]j[/tex] indicates the vertical coordinate.
As a vertical or colum vector would be
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
Therefore, the answer is
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
