Answer:
She can make 9 uniform tops from the material left.
Step-by-step explanation:
Given:
Yards of material left on the bolt = 
Material requirement for a uniform top for band members = 
To find the number of tops that can be made from the material left.
Solution:
In order to find the number of tops that can be made from
yards of material, we need to divide
by
.
Number of uniform tops that can be made is given as:
⇒ 
We first convert mixed number to fractions.
⇒ 
To divide fractions the fractions are multiplied after flipping the divisor.
⇒ 
⇒ 
⇒ 9
Thus, she can make 9 uniform tops from the material left.
f(5) means to replace x in the equation with 5 then solve.
f(x) = x^2 +2x
f(5) = 5^2 + 2(5)
f(5) = 25 +10
f(5) = 35
The answer is D)35
Answer:
The correct order is:
a
c
d
b
Step-by-step explanation:
First, let's write 1/x in a convenient way for us:
a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:
d) Observe that x is the quotient of two integers with the denominator nonzero.
And that is the definition of rational, then we end with:
b) Hence x is rational.
Which is what we wanted to get.
Answer:

Step-by-step explanation:
Let r represent Linda's walking rate.
We have been given that Linda can ride 9 mph faster than she can walk, so Linda's bike riding rate would be
miles per hour.

We have been given that Linda can bicycle 48 miles in the same time as it takes her to walk 12 miles.


Since both times are equal, so we will get:

Therefore, the equation
can be used to solve the rates for given problem.
Cross multiply:





Therefore, Linda's walking at a rate of 3 miles per hour.
Linda's bike riding rate would be
miles per hour.
Therefore, Linda's riding the bike at a rate of 12 miles per hour.

Answers:
Rate of change = -5
Initial value = 25
Step-by-step explanation:
Each time x increases by 2 (eg from x = 1 to x = 3), the value of y drops by 10 (eg from y = 20 to y = 10)
Therefore the slope is...
slope = rise/run = (change in y)/(change in x) = -10/2 = -5
slope = -5
So each time x increases by 1, y will decrease by 5
Flip things around: each time x decreases by 1, y will increase by 5
So the pair (x,y) = (1,20) shown in row 1 of the table leads to (0,25) based on the rule above. Another way to see this is to plug m = -5, x = 1 and y = 20 into y = mx+b and solve for b to get b = 25
