Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)

Molly's hair was 20 inches long. Three years later it was 53 inches long. What was the percent increase, to the nearest hundredth, of Molly's hair length.
Find how much it grew:
53 - 20 = 33 inches.
Divide the amount it grew by the original length
33/20 = 1.65
Subtract 1:
1.65 - 1 = 0.65
Multiply by 100 for percent:
0.65 x 100 = 65%
The percent increase is 65%
The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent
the larger number and y represent the smaller number. Which equations represent this situation?

y = 3X+ 3
y=-x
10
y = 3
Answer:
y = -x and 2y = 3x - 10 is the system of equations.
Step-by-step explanation:
Let,
Larger number = x
Smaller number = y
According to given statement;
x + y = 0
y = -x
And
3x - 2y = 10
Or it can be written as;
2y = 3x - 10
Therefore,
y = -x and 2y = 3x - 10 is the system of equations.

Answer:
[tex]-5(g - 3h + 5)[/tex]
Step-by-step explanation:
Given
[tex]-5g + 15h - 25[/tex]
Required
Factor using a negative factor
Express each term as a factor of -5
[tex]-5*g - 5*-3h - 5 * 5[/tex]
Factor out -5
[tex]-5(g - 3h + 5)[/tex]
Hence:
The factored form of [tex]-5g + 15h - 25[/tex] is [tex]-5(g - 3h + 5)[/tex]

a= 1/2(5h+3)h
Answer:
99
Step-by-step explanation:
If you do that math then you get 99
Answer:
[tex]a = \frac{1}{2} (5h + 3)h \\ = \frac{1}{2} (5 \times 6 + 3)6 \\ = \frac{1}{2} (33 \times 6) \\ = \frac{1}{2} \times 198 \\ a= 99[/tex]

Consider the Pareto chart, which shows the number of student blood donors by their type for one day of a campus blood drive. How many students donated blood on that day?
Question attached
Answer:
130
Step-by-step explanation:
Number of students old donors can be calculated from the Pareto chart by adding number of blood donors on the different bars:
Type 0= 50
Type A= 35
Type B =30
Type AB =15
Therefore 50+35+30+15=130 blood donors

Solve this system by Elimination 2x+y=2
4x+2y=-4
Answer:
x= 1 - y/2
Step-by-step explanation:
1. Subtract y from both sides. 2x=2−y
2. Divide both sides by 22.
x=\frac{2-y}{2} x= 22−y
3. Simplify \frac{2-y}{2}
22−y to 1-\frac{y}{2}1−2y. and there u get ur answer x=1−2y
this is for "2x+y=2" btw hope this helped!

Shannon is making a pile of square origami paper, whose sides are measured as 4n + 3. Form an expression that is equivalent to the perimeter of one sheet of the origami paper. Be sure to show the steps taken to produce your expression.
Answer:
16n+12
Step-by-step explanation:
If all four sides measure 4n+3, then the perimeter is 4 times the length of each side. 4(4n+3) = 16n + 12 = perimeter

1) a^-8/5
2) (9b^4)^2/3
3) (8x^5)5/7
PLEASE I NEED HELP!!!!!!
Answer:
1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third
Step-by-step explanation:
1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5
2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3
3) The same applies to this as the 2nd, we just multiply to get 8x^25/7

Answer:
Neither
Step-by-step explanation:
Triangles are similar if their angles are the same, and if the sides are changed by a proportional ratio. The angles for FED and ZXY are not the same. Therefore, they are not similar
Answer:
D. Neither
Step-by-step explanation:
Similar triangles are scaled versions of each other. Two triangles that are similar will have congruent angles. Hence, to find a triangle that is similarto ABC, the angles of the other triangles will be congruent to the given angles of ABC. As one can see, no other triangle has congruent angles to ABC, and hence the answer is D, neither of the two triangles are similar to ABC.

Answer:
1. C) 3
2. D) -1
3. D) 7^2 - 8*2 - 16
4. B) 75
5. B) 6^2 + (2 - 8)*sqrt(81)
Step-by-step explanation:
1. (10 - (6-4)^2)/2
= (10 - 2^2)/2
= (10 - 4)/2
= 6/2
= 3
2. PEMDAS states that Multiplication is before Subtraction
8 - (5^2-7)/2
= 8 - (25-7)/2
= 8 - 18/2
= 8 - 9
= -1
3. D) 7^2 - (8*2) - 16
= 49 - 16 - 16
= 49 - 32
= 17
4. 3(2 + 3)^2
= 3(5)^2
= 3(25)
= 75
5. 6^2 + (2 - 8)*sqrt(81)
= 36 + (-6*9)
= 36 - 54
= -18

The picture below shows a pole and its shadow:
A pole is shown with a right triangle side. The right triangle has hypotenuse 221 cm and base 21 cm.
What is the height of the pole?
121 centimeters
220 centimeters
225 centimeters
Answer:
the height of the pole is 220 centimeters
Step-by-step explanation:
The computation of the height of the pole is shown below
Here we applied the pythagoras theorem
Given that
Hypotenuse = 221 = c
And, base = 21 cm = b
a^2 + b^2 = c^2
So, the height is
= 21^2 cm - 221 cm
= 441 cm - 221 cm
= 220 cm
Hence, the height of the pole is 220 centimeters
