Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155
Answer:
A. 0.40x - 15=155
Step-by-step explanation:
40% can be written as 0.40
x = total money earned
-15 from that total
The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155
Let :
monthly allowance = X Designer bag purchase = 40% of X = 0.4X Donation to charity = $15Total amount left = $155Percentage left after bag purchase :
1 - 0.4X = 0.6X0.6X - charity = amount left
Therefore, the required expression is 0.6X - 15 = 155

What is the slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) ? (−16,−18)? Write your answer in the simplest form.
The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.
Calculation of the slope of the line:here we used the following formula
So,
[tex]= y_2-y_1\div x_2-x_1[/tex]
So,
-18-6=-24
And,
-16-4=-20
Now
[tex]= -24\div -20[/tex]
= 1.2
Hence, The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
[tex]m = \dfrac{y-q}{x-p}[/tex]
Given that the line that passes through the points (4, 6) and (-16, -18)
WE need to find the slope of the line.
Since, [tex]m = \dfrac{y-q}{x-p}[/tex]
Therefore, m = -18 - 6 / -16 - 4
m = 24 / -20
m = 6/5
Hence, The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.

A pharmacist put 4.536 ounces of vitamin pills into bottles. She put .042 ounce of vitamin pills into each bottle.
How many bottles did the pharmacist use for these vitamin pills?
Answer:
108 bottles
Step-by-step explanation:
the total is 4.536 oz of vitamin pills
each bottle can accomodate 0.042 oz of vitamin pills
to know the quantity of each bottle
we calculate
0.042 oz of vitamin pills = 1 bottle
4.536 oz of vitamin pills = (4.536 x 1)/0.042=108
so therefore 4.536 oz of vitamin pills will accommodate 108 bottles

1. Find the lengths of the diagonals of rectangle QRST , Given that QS = 6X+3 and RT = 8X-1
2. If QR=9 , Find the length of TQ (Hint: There is a right angle in the Corner!)
Answer:
1. QS and RT= 15
2. Im not positive but I think it's TQ=18
Step-by-step explanation:
For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2
Then you'd plug in 6 and get QS and RT=15
For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need

PLEASE HELP!!! No fake questions please, I just want some help on my homework nothing else. For those of you who post fake answers and inappropriate comments for your entertainment, you really must have some physiological problems and I suggest getting professional help. Thank You!
Answer:
Radius is the distance from the center outwards
Diameter goes straight across the circle, through the center.
Step-by-step explanation:
Hope this Helps!!
let me know if it doesn't
Answer:
Step-by-step explanation:
Diameter is the longest line that you can draw in a circle passing through the centre of the circle.
Radius is the line joining the centre of the circle to any point on the circumference.
Explanation:
Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter.
D=2x radius and radius =D/2
Actually pi is defined to be the ratio of the circumference of the circle to the diameter of the circle. Therefore, you can solve for the diameter from that equation.
π=C/D , D=C/π Or , C=π x D
