Answer:
A =4320 in^2
Step-by-step explanation:
The area of a rectangle is found by
A= l*w
We need to convert yd to inches since the units have to be the same
4 yd * 36 inches /1 yd = 144 inches
A = 30 inches * 144 inches
A =4320 in^2

Answer:
h= [tex]\frac{−2.094395r3+v}{1.047198r2}[/tex]
Step-by-step explanation:
v=( [tex]\frac{1}{3}[/tex] (3.141593))(r2)(2r+h)
Step 1: Flip the equation.
1.047198hr2+2.094395r3=v
Step 2: Add -2.094395r^3 to both sides.
1.047198hr2=−2.094395r3+v
Step 3: Divide both sides by 1.047198r^2.
h= [tex]\frac{−2.094395r3+v}{1.047198r2}[/tex]
Answer:
[tex]h = \frac{3v - 2\pi \: r{ }^{3} }{\pi \: r {}^{2} } [/tex]
Step-by-step explanation:
Step 1 add -2/3Πr^3 to both sides
v + -2/3Πr^3 = 1/3hpr^2 + 2/3Πr^3 + -2/3Πr^3
Step 2 divide both sides by (Πr^2)/3
(v + -2/3Πr^3)/(Πr^2)/3 = (1/3hΠr^2)/(Πr^2)/3
(3v - 2Πr^3)/Πr^2 = h

Mr. Williams is driving on a highway at an average speed of 50 miles per hour. His destination is 100 miles away. The
equation d - 100 - 50t gives the distance d (in miles) that he has left to travel as a function of the time t (in hours) that he has
been driving. Write and interpret the inverse of this function (2 points per part).
a. Solve the equation for t by
filling in the empty spaces.
d = 100 - 50
Write the equation.
d-
100 = - 50t
Subtract 100 from both sides.
D-100/-50=t
Divide both sides by -50.
D/-50+2=t
Simplify the left side.
b. Use the inverse function to find the time that Mr. Williams has left to travel when he has driven 75 miles.
Answer:
t = -d/50 + 2
0.5 hour
Step-by-step explanation:
Given the equation:
d = 50 - 100t
The inverse function:
A.) solving for t
d = 100 - 50t
d - 100 = - 50t
Divide both sides by - 50
d/-50 - (100/-50) = - 50t/-50
-d/50 - (-2) = t
t = -d/50 + 2
B) using the inverse function:
t = -d/50 + 2
Miles driven (d) = 75, find time (t)
t = - 75/50 + 2
t = - 1.5 + 2
t = 0.5
t is in hours, therefore time left to travel is 0.5 hours or 30 minutes

Which value in scientific notation is about 9,802,733?
A. 9 x 105
B.
9 x 106
C.
9 x 107
D.
9 x 108
Answer:
B
Step-by-step explanation:
One million has 6 zeros.
9 x 10^5 = 900, 000
9 × 10^6 = 9, 000, 000
9 x 10^7 = 90, 000, 000
9 x 10^8 = 900, 000, 000
The correct answer is 9 × 10^6
Answer:
Option B
Step-by-step explanation:
=> 9,802,733
The decimal point will come after the first non zero digits and since six digits come after it , So the exponent/power/indices will be 6
So, it becomes:

Amrita thinks of a number. She doubles it, adds 9 , divides her answer by 3 and finally subtracts 1 . She obtains the same number she originally thought of. What was Amrita's number?
Answer:
Amrita's number is 6
Step-by-step explanation:
x Double the unknown number
2x Add 9
2x + 9 Divide the answer by 3
2/3x + 3 Subtract 1
2/3x + 2 Set this equal to the original number
2/3x + 2 = x
-2/3x -2/3x Subtract 2/3x from both sides
2 = 1/3x Multiply both sides by 3
6 = x
Amrita's number was 6.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number = x
We can write an expression from the given statement.
{ (2x + 9) ÷ 3 } - 1 = x
Solve for x.
{ (2x + 9) ÷ 3 } - 1 = x
(2x + 9)/3 - 1 = x
2x + 9 - 3 = 3x
Add 3 on both sides.
2x + 9 = 3x + 3
Subtract 9 on both sides.
2x = 3x + 3 - 9
2x = 3x - 6
6 = 3x - 2x
x = 6
We can cross-check.
{(2 x 6 + 9) ÷ 3} - 1 = 6
{(12 + 9) ÷ 3} - 1 = 6
7 - 1 = 6
6 = 6
Thus,
The number was 6.

What is the length of BC in the right below?
Answer:
B. 17
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²

Answer:
To find the length of BC we use Pythagoras theorem.
BC² = AB² + AC²
AB = 8 AC = 15
BC² = 8² + 15²
BC = √64 + 225
BC = √ 289

The straight line L has the equation 4y=5x+3
The point A has coordinates (3,-2)

Write your answer in the form y=Mx+c
Answer:
y = -4/5x + 2/5
Step-by-step explanation:
[tex]4y=5x+3\\write -in ; y=mx+b -form\\y = \frac{5}{4} x + \frac{3}{4} \\m = 5/4\\m_1m_2 = -1\\5/4m_2 =-1\\m_2 = -4/5\\ (3,-2)\\x = 3\\y = -2\\y = mx+b\\-2 = -\frac{4}{5}(3) +b\\-2 = -12/5 +b\\-2+12/5 = b\\2/5 = b\\m = -4/5\\Substitute -new-values-into-slope-intercept-form\\y = mx+b\\y = -4/5x + 2/5[/tex]
The equation of a line perpendicular and passing through (3, - 2)
is y = - (4/5)x + 19/2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines perpendicular to each other have slopes that are negative reciprocals of each other.
Given line is, 4y = 5x + 3.
y = (5/4)x + 3/4.
So, The line perpendicular to it must have a slope of - (4/5) passing through the point (3, - 2).
- 2 = - (4/5)×3 + b.
- 2 = - 12/5 + b.
b = 12/5 + 2.
b = (12 + 7)/2.
b = 19/2.
Therefore, y = - (4/5)x + 19/2.

Answer:
length of C'B' = 15units (B)
Step-by-step explanation:
Original image is ∆ABC
A = (8,15)
B = (12, 13)
C = (8,10)
Scale factor = 3
Since the circle would be dilated by a scale factor of 3 about the origin, Do(x,y) →3(x,y)
Coordinates of ∆A'B'C'
A' = 3(8, 15) = (24, 45)
B' = 3(12, 13) = (36, 39)
C' = 3(8, 10) = (24, 30)

A rectangle has a length 2 cm larger than its width.
(a) If the perimeter of the rectangle is 14 cm, what are the dimensions of the rectangle?
Answer:
The width is 5/2 = 2.5 cm
The length is 9/2 = 4.5cm
Step-by-step explanation:
The length is 2 longer than the width
l = w+2
The perimeter is 14
P =2 ( l+w)
14 = 2 (l+w)
Replace l with w+2
14 = 2 ( w+2+w)
14 =2 (2w+2)
Divide each side by 2
14/2 = 2/2(2w+2)
7 = 2w+2
Subtract 2
7-2 = 2w+2-2
5 = 2w
Divide by 2
5/2 = w
The length is w+2
5/2+2
5/2+4/2 = 9/2
The width is 5/2 = 2.5
The length is 9/2 = 4.5
