Two punches are made from steel bar stock 9 7/16 inches long. If one punch is 4 1/64 inches long and the other is 4 3/32 inches long, how many inches of stock are wasted?
a. 1 1/16 inches
b. 1 5/16 inches
c. 1 15/64 inches
d. 1 21/64 inches
Answer:
d. 1 21/64 inches
Step-by-step explanation:
Add the lengths of the two punches.
4 1/64 + 4 3/32 = 4 1/64 + 4 6/64 = 8 7/64
Subtract the sum from the length of the bar stock.
9 7/16 - 8 7/64 = 9 28/64 - 8 7/64 = 1 21/64
Answer: d. 1 21/64 inches
The 1 15/64 inches of stock are wasted (option c).
To find out how much stock is wasted, we need to subtract the sum of the lengths of the two punches from the original length of the steel bar.
Original length of the steel bar = 9 7/16 inches
Length of the first punch = 4 1/64 inches = 4 + 1/64 inches
Length of the second punch = 4 3/32 inches = 4 + 3/32 inches
Total length of the two punches = (4 + 1/64) + (4 + 3/32) inches
Now, add the lengths of the two punches:
Total length of punches = 8 + 1/64 + 3/32 inches
Convert the fractions to a common denominator (64):
Total length of punches = 8 + 1/64 + 6/64 inches
Total length of punches = 8 + 7/64 inches
Now, subtract the total length of punches from the original length of the steel bar:
Wasted stock = 9 7/16 - (8 + 7/64) inches
Convert 9 7/16 to an improper fraction:
Original length of the steel bar = 9 * 16/16 + 7/16 = 151/16
Now, subtract the total length of punches:
Wasted stock = 151/16 - (8 * 16/16 + 7/64)
Wasted stock = 151/16 - (128/16 + 7/64)
Wasted stock = 151/16 - 130/16 - 7/64
Wasted stock = 21/16 - 7/64
Wasted stock = (21 * 4)/(16 * 4) - 7/64
Wasted stock = 84/64 - 7/64
Wasted stock = 77/64 inches
Now, let's simplify 77/64:
77/64 = 64/64 + 13/64 = 1 + 15/64 inches

Leticia spends $18. 45 on a shirt. She spends at least $3. 00 more than Humberto spends. If h represents the amount Humberto spends, which symbol can be used to complete the inequality below to represent this situation? 18. 45 blank 3 h > < Greater-than-or-equal-to Less-than-or-equal-to.
Inequality is the comparison of mathematical expressions which are not strictly equal. The needed inequality is: 18.45 ≥ 3 + h
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case, we've got:
Amount spent by Leticia = $18.45
Amount spent by Humberto = h dollars
Since amount spent by Leticia is at least $3. 00 more than what Humberto spends, thus:
18.45 is at least h + 3 (all in dollars)
(we usually skip stuffs like currency sign or units in equations or inequalities, to keep things as minimized as possible. It is known from the context what unit or currency or such thing is being discussed).
At least can be thought of as equal to that quantity or greater than that quantity but not less than that quantity.
This more than or equal to is written as ≥
Thus, the inequality we get is:
18.45 ≥ 3 + h

If 2 miles is equal to 3,218.7meters, how many meters are there in 7 miles
Given the function f(x)=3x^2+4x−4
find the following.
(a) the average rate of change of f on [−4,0].
(b) the average rate of change of f on [x,x+ℎ].
Answer:
(a) -8
(b) 6x +4 +3h
Step-by-step explanation:
Sometimes, it works well to find the general solution first, then use that to solve the specific problem. That's what we'll do here.
(b)The average rate of change on the interval [x, x+h] is defined as ...
m = (f(x+h) -f(x))/h
For the given f(x), this is ...
[tex]m=\dfrac{((3(x+h)^2+4(x+h)-4)-(3x^2+4x-4)}{h}\\\\m=\dfrac{3x^2 +6xh+3h^2+4x+4h-4-3x^2-4x+4}{h}\\\\m=\dfrac{6xh+3h^2+4h}{h}\\\\\boxed{m=6x+4+3h}\qquad\text{average rate of change on $[x,x+h]$}[/tex]
__
(a)Using the above result for the interval [-4. 0], we have x=-4 and h=4. The average rate of change on that interval is ...
m = 6(-4) +4 +3(4) = -24 +4 +12 = -8
The average rate of change on [-4, 0] is -8.
_____
Additional comment
In the above, we worked the generic problem first. That way, we only needed to expand f(x+h)-f(x) once. If you're not terribly comfortable with doing algebra on literal expressions, sometimes it is more comfortable to work the numerical problem--as this question would have you do. This lets you get an idea of the kinds of operations that are involved and the way terms combine.
We note that the average rate of change is the instantaneous rate of change (derivative of the function) at the midpoint of the interval. That derivative is the value of m when h=0: 6x+4. The midpoint of the interval [-4,0] is x=-2, and the derivative there is 6(-2)+4 = -8, as above.

2p-q=7 and 3p+2q=7 solve using simultaneous equation
Answer:
q = -1 and p = 3
Step-by-step explanation:
make q the subject of the formula
q = 2p - 7
Let use the other equation to manipulate data
3p + 2q = 7
:3p + 2 (2p - 7) = 7
:3p + 4p - 14 = 7
:3p + 4p = 7 + 14
:7p = 21
7. 7
like terms cancel each other
thus
p = 3
ANDwe the first equation to find the value of q
q = 2p - 7
since we have find p as 3, let's substitute
q = 2 (3) - 7
q = 6 - 7
q = -1
