Answer: 5/8
Step-by-step explanation:
You could convert 1/4 to 2/8 because the numbers you're subtracting have a common factor of 2. After subtracting 2/8 from 7/8, you're left with 5/8.
Answer:
7/8 - 1/4 = 5/8
Step-by-step explanation:
The equation is 7/8 - 1/4 = ?
So you need to have a common denominator for both fractions in order to subtract the two.
In order to make 7/8 and 1/4 have a common denominator, multiply 1/4 by 2. Then it becomes 2/8.
Now you can subtract the two fractions because they both have a common denominator.
7/8 - 2/8 = 5/8

Answer: 2.9
Step-by-step explanation:
area of roof = (.5)(base of house)(left side - right side)
area of roof = (.5)(2)(2.8 - 1.8)
area of roof = (.5)(2)(1) = 1
area of bottom = left height x base of house
area of bottom = 1.8 x 2 = 3.6
area of house = area roof + area bottom
area of house = 1 + 3.6 = 4.6
area without door = area house - area door
area door = door height x door width
area door = 1.7 x 1
area door = 1.7
area without door = 4.6 - 1.7 = 2.9

Ursula is starting a new national network of science fiction book clubs. The establishment and expansion of the network is as follows. The original network began with eight people in each club and four clubs in each of two states. Every month, the number of people in each club increases by two and the number of clubs in each state grows by one. The number of states where the groups exist also increases by one every month. The total number of people in the network of book clubs is represented by the expression below, where x is the number of months since the clubs were established.
Using derivatives, it is found that the correct option is given by:
A. The expression 2x² + 20x + 32 represents the average rate of increase in the total number of clubs in the network across all states.
What is the meaning of the derivative of a function?It is the rate of change of the function over a period of time.
In this problem, the total number of people in the book club after x months is given by:
f(x) = 2x³ + 20x² + 64x + 64
The derivative is given by:
f'(x) = 4x² + 40x + 64 = 2(2x² + 20x² + 32).
It represents the average rate of change across all states, hence option A is correct.

Answer:
arc RS = 60°
Step-by-step explanation:
the secant- secant angle P is half the difference of ots intercepted arcs, that is
40° = [tex]\frac{1}{2}[/tex] (QT - RS ) ← multiply both sides by 2 to clear the fraction
80° = QT - RS
80° = 140° - RS ( subtract 140° from both sides )
- 60° = - RS ( multiply both sides by - 1 )
60° = RS

A line passes through the point (-8,5) and has a slope of -3/4 .
Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
Formula
The basic formula is
y = mx + b
m = the slope
b = the y intercept
What you know so far
y = mx + b.
You know that the slope = -3/4
y = - 3/4 x + b
y intercept
The point is used to find the y intercept.
x = - 8
y = 5
Subtitute these two values into the equation above.
5 = -3/4 * (-8) + b Multiply the factors on the right
5 = 6 + b Subtract 6 from both sides
5 - 6 = b Combine
-1 = b
Answer: y = -(3/4) x - 1
Answer:
[tex]\Longrightarrow:\boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Step-by-step explanation:
Use the slope-intercept form.
Slope-intercept form:
[tex]\Longrightarrow: \sf{y=mx+b}[/tex]
The m represents the slope.The b represents the y-intercept.X= (-8)
Y= 5
[tex]\sf{5=-\dfrac{3}{4}*(-8)+b}[/tex]
5=6+b
Subtract the sign.
5-6=b
Solve.
Isolate the term of b from one side of the equation.
Subtract the numbers from left to right.
⇒ 5-6=-1
⇒ -1=b
Change the equation.
⇒ b=-1
So, therefore, the y-intercept is -1.
[tex]\Longrightarrow: \boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Therefore, the correct answer is y=-3/4x-1.I hope this helps! Let me know if you have any questions.

You want to get a pizza that costs $12.75. Tax
6%. How much will the pizza cost in all? Round
to the nearest cent.
Answer:
$13.52
Step-by-step explanation:
Since we know the tax rate is 6%, we can multiply by 12.75*6/100 to get how much the tax would be added to the total. We get 0.765. And now we add 0.765 and 12.75 to get 13.515. Since it's asking to round to the nearest cent, we get $13.52

Find the slope of the line that is parallel and perpendicular to the following equation.
y + 4 = -3(x +1)
Answer:
Parallel: -3
Perpendicular: 1/3
Step-by-step explanation:
First I would convert the equation into slope-intercept form to more easily identify the slope:
[tex]y+4=-3x-3\\ y=-3x-7[/tex]
Slope-intercept form is defined as y=mx+b where m is the slope and b is the y-intercept so we can identify the slope of this line as -3.
When a line is parallel to another line, this means that they have the same slope, therefore the slope of the line parallel to the equation is -3.
Perpendicular lines will have slopes that are negative reciprocals of each other, the negative reciprocal of -3 is 1/3; therefore, the slope of the line perpindicular to the equation is 1/3.
Answer:
parallel slope = -3
perpendicular slope: [tex]\sf \bold{\frac{1}{3} }[/tex]
Explanation:
y + 4 = -3(x +1)y + 4 = -3(x) - 3y = -3(x) - 3 - 4y = -3x - 7comparing with y = m(x) + b [ "m" is the slope, "b" is the y-intercept ]
slope: -3y-intercept: -7Parallel/Tangent slope:
m₁ = m₂ (same)
Perpendicular/Normal slope:
