The wheels on an adult size 4-wheeler has a radius of 14 inches. What is the distance the wheel will travel in one full rotation?
Distance cover in full rotation is 87.92 inches
Full rotation distance:Given that;
Radius of wheel = 14 inches
Find:
Distance cover in full rotation
Computation:
Distance cover in full rotation = Circumference of wheel
Distance cover in full rotation = 2πr
Distance cover in full rotation = 2(3.14)(14)
Distance cover in full rotation = (6.28)(14)
Distance cover in full rotation = 87.92 inches

Mr. Ailey gave his class 45 minutes to read. Davida reads 27 3/4 pages in that time. At what rate, in pages per hour, did Davida read?
A 42
B 36
C 34
D 37
Answer:
37 pages per hour
Step-by-step explanation:
Given that :
Time Given to read = 45 minutes ; 45 / 60 = 0.75
Number of pages readable ad by Davida within the given time frame = 27 3/4 pages
David's reading rate in pages per hour :
Number of pages read / time taken (hrs)
[27 3/4] ÷ (45/60)
[111 / 4] ÷ (45/60)
(111 / 4 ) * (60/45)
(111 * 60) / (4 * 45)
6660 / 180
= 37 pages per hour

Look at the figure below:
An image of a right triangle is shown with an angle labeled y.
If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°?
cos y° = 6 divided by b
cos y° = 6a
cos y° = 6b
cos y° = b divided by 6
Answer:
The third one is the answer
Building B; it is around 16.35 feet taller than building A
Look at the figure below: an image of a right triangle is shown with an angle labeled y If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°?
cos y° = 6 divided by b cos y° = 6a cos
If sin f° = 8/9 and the measure of YW is 24 units, what is the measure of YX?
24 units
Using the understanding of trigonometric ratios, cos y = b/6.
What are trigonometric ratios?The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
tan y = a/b
sin y = a/6
tan y = sin y/ cos y
cos y = sin y /tan y = (a/6)/(a/b) = b/6

Lexi has $20 in a savings account that earns 10% interest per year. The interest is not
compounded. How much interest will she earn in 1 year?
Use the formula 1 = prt, where I is the interest earned, p is the principal (starting amount), r
is the interest rate expressed as a decimal, and t is the time in years.
Answer:
She earns $2 in interest in 1 year.
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
Lexi has $20 in a savings account that earns 10% interest per year. The interest is not compounded.
This means that [tex]P = 20, I = 0.1[/tex]
How much interest will she earn in 1 year?
This is E when [tex]t = 1[/tex]. So
[tex]E = P*I*t = 20*0.1*1 = 2[/tex]
She earns $2 in interest in 1 year.

What is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swimming 30 m below the surface?
Answer: 130 meters
Step-by-step explanation:
We have to let the "surface of the ocean" be at 0 height.
So,
anything above surface has POSITIVE height
and anything below surface has NEGATIVE height
The albatross is 100 m above, so we can say its height is:
+100 meters
The shark is 30 m below, so we can say its height is:
-30 meters
The difference in height is thus:
100 - (-30) = 100 + 30 = 130 meters

You go to a restaurant with a friend. You purchase the items shown in the table below. There is a 7% sales tax and you wish to leave a 20% tip. You also have a coupon for 15% off the meal. What will you pay for the meal?
The total money paid for a meal of $100 with 7% sales tax, 20% tip and a coupon for 15% off is $112.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let us assume that the total cost of the meal shown in the table cost $100, hence:
Tax = 7% of sales = 0.07 * 100 = $7
Tip = 20% of sales = 0.2 * 100 = $20
Coupon = 15% = 0.15 * 100 = $15
Amount paid for meal = total cost + tax + tip - coupon = 100 + 7 + 20 - 15 = $112
The total money paid for a meal of $100 with 7% sales tax, 20% tip and a coupon for 15% off is $112.

Answer: a) one central angle is QPR
b) arc QTS is a semicircle
c) arc QR is a major arc
d) arc QTR = 235
e) arc QR = 125
Step-by-step explanation:
A central angle is an angle with its vertex as the midpoint of the circle.
A semicircle is half of a circle. Segment QS goes through the midpoint P splitting the circle in half : arc QTS and arc QRS are both semicircles.
The degree of a central angle is equal to the arc it encompasses. Central angle QPR is equal to 125, therefore arc QR is equal to 125 as well.
Given this information we can now find the remaining arc QTR. A circle is equal to 360 degrees. We know part of the circle is 125 degrees which means the remaking portion must be 235 degrees.
360 - 125 = 235

Which expression is equivalent to 6x+7-12*2-(3 to the power 2 +3)-x
Step-by-step explanation:
Questions about equivalent expressions usually feature both simple expressions and complex expressions. To check which complex expression is equivalent to the simple expression:
Distribute any coefficients: a(bx\pm c)=abx\pm aca(bx±c)=abx±aca, left parenthesis, b, x, plus minus, c, right parenthesis, equals, a, b, x, plus minus, a, c.
Combine any like terms on each side of the equation: xxx-terms with xxx-terms and constants with constants.
Arrange the terms in the same order, usually xxx-term before constants.
If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Example
How do we solve for unknown coefficients?
Some questions will present us with an equation with algebraic expressions on both sides. On one side, there will be an unknown coeffient, and the question will ask us to find its value.
For the equation to be true for all values of the variable, the two expressions on each side of the equation must be equivalent. For example, if ax+b=cx+dax+b=cx+da, x, plus, b, equals, c, x, plus, d for all values of xxx, then:
aaa must equal ccc.
bbb must equal ddd.
To find the value of unknown coefficients:
Distribute any coefficients on each side of the equation.
Combine any like terms on each side of the equation.
Set the coefficients on each side of the equation equal to each other.
Solve for the unknown coefficient.
Example
How do we rearrange formulas?
Formulas are equations that contain 222 or more variables; they describe relationships and help us solve problems in geometry, physics, etc.
Since a formula contains multiple variables, sometimes we're interested in writing a specific variable in terms of the others. For example, the formula for the area, AAA, for a rectangle with length lll and width www is A=lwA=lwA, equals, l, w. It's easy to calculate AAA using the formula if we know lll and www. However, if we know AAA and www and want to calculate lll, the formula that best helps us with that is an equation in which lll is in terms of AAA and www, or l=\dfrac{A}{w}l=
w
A
l, equals, start fraction, A, divided by, w, end fraction.
Just as we can add, subtract, multiply, and divide constants, we can do so with variables. To isolate a specific variable, perform the same operations on both sides of the equation until the variable is isolated. The new equation is equivalent to the original equation.
The value of equivalent expression is,
⇒ 5x - 29
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 6x + 7 - 12 × 2 - (3² + 3) - x
Now, We can simplify as;
⇒ 6x + 7 - 12 × 2 - (3² + 3) - x
⇒ 6x + 7 - 24 - (9 + 3) - x
⇒ 6x + 7 - 24 - 12 - x
⇒ 5x - 29
Thus, The value of equivalent expression is,
⇒ 5x - 29
