Lauren has a purse full of dimes and quarters. She has 25 less dimes than quarters. If she has a total of $10.45, which system of equations would she write to find the number of dimes, d and quarters, q?
Answer:
D(0.10) + Q(0.25) = 10.45
Q = D + 25 (or Q - D = 25)
Step-by-step explanation:
D = number of dimes
Q = number of quarters
D(0.10) + Q(0.25) = 10.45
Q = D - 25 (or D - Q = 25)
We multiply the number of dimes she has by $0.10, because that is the worth of each dime, and we multiply the number of quarters she has by $0.25 because that is the worth of each quarter. We then set that equal to $10.45, the overall value of her coins.
Because she has 25 less dimes than quarters, the number of dimes she has should be 25 less than the number of quarters she has. So the number of quarters she has should be equal to the number of dimes she has plus 25.

A force of 192 lb is required to hold a spring stretched 3 ft beyond its natural length. How much work W is done in stretching it from its natural length to 6 inches beyond its natural length
Answer:
The work done in stretching the spring is 8 lb.ft
Step-by-step explanation:
Given;
Applied force, F = 192 lb
extension of the spring, x = 3 ft
Determine the spring constant from the applied force and extension;
[tex]k = \frac{F}{x} \\\\k = \frac{192 \ lb}{3 \ ft} \\\\k = 64 \ lb/ft[/tex]
When the spring is stretched 6 inches beyond its natural length, the work done is calculated as follows;
x = 6 inches = 0.5 ft
[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} (64 \ lb/ft)(0.5 \ ft)^2\\\\W = 8 \ lb.ft[/tex]
Therefore, the work done in stretching the spring is 8 lb.ft

Write the following equation in standard form and show your work : x^2+y^2-22y+96=0
Answer:
[tex]x^2 + (y-11)^2 = 5[/tex]
Step-by-step explanation:
Completing the square gives us that
[tex]x^2+y^2-22y+96=0\\x^2 + (y-11)^2 - 11^2 + 96 = 0\\x^2 + (y-11)^2 = 121 - 96\\x^2 + (y-11)^2 = 25\\x^2 + (y-11)^2 = 5[/tex]
Which is the standard form of a circle.

Answer:
convert the task into ratios
(1) if $24 = 4 walks
how many $ for a walk
= (24/4) $/walk
= $6 per walk
•the first one is correct
•the second is wrong, cause it interprete $12/3 walks, which is rationalized to $3 per walk
•the third one is correct, cause it can also be rationalized ($30/5walks) to $6 per walk.
also, rationalizing this would equate to 3 miles per hour (6miles/2hrs)
• one is wrong cause it's 4 miles per hour
•two is correct, it's saying 3 miles per hour (12/4)
• third, likewise is correct 3 miles per hour (9/3) miles/hrs

A.
x – 0.10x
B.
x(1 – 0.10)
C.
x – 1.10x
D.
0.90x
Answer:
C
Step-by-step explanation:
This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.

What is the value of x in the figure? Enter your answer in the box. 145 degrees and (2x + 15) degrees
Answer:
65°
Step-by-step explanation:
2x + 15° = 145° ( being vertically opposite angles)
2x = 145° - 15°
2x = 130°
x = 65°
Hope it will help :)✔
The value of x is 65 degrees.
What is Vertically opposite angle?When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.
Given:
angles are: 145 and (2x +15)
As, the pair of angle are in relation of vertically opposite angle
145 = 2x +15
2x= 130
x= 130/2
x= 65 degree.
