Suzy has a collection of quarters and dimes. Together she has 34 coins worth $6.40. How many quarters and how many dimes does Suzy have?
Please show your work :)
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14

PLEASE HELP I will give Brainly to however gets it right. Miguel's irrigation tank for his large garden had 15.5 gallons of water before he began to
fill it at a rate of 1.4 gallons per minute.
Alejandro checked his irrigation tank and found it contained 45.5 gallons, before he
began draining his tank at a rate of 0.6 gallons per minute.
After how many minutes will the two irrigation water tanks have the same amount of
water?
Answer:
It will take 50 minutes.
Step-by-step explanation:
Because if you are trying to get 45.5 to 15.5 you need to drain 30 gallons of water, and to do that it will take 50 minutes because 0.6*50=30.

what is the answer to this?
Answer:
Well in a standard equation you have y=mx + b Mx is the slope and b is the y-intercept So take a shot and solve it now!Part A:
Draw arrows on the graph below for RISE and RUN. *Remember to start at the left point.*
Part B: Find the slope of the line from the graph above. *Don't forget to simplify!*
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{2}[/tex]
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.

Step-by-step explanation:
if you say 1<2 and multiply both by negative 3 you will have -3 > -6
Answer:
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Answer:
i mean might as well get free points now that its 2 weeks old
Step-by-step explanation:
Answer:
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
so: a2+b2=c
2502+1002=c2
2500+10000=c2
12500=c2
c=√12500
c=111.80 yards

Which of the following is a counterexample for the hypothesis "All parallelograms are rectangles"?
Answer:
The answer would be B
Step-by-step explanation:
A non-square rhombus. A non-square rhombus (also known as a rhombus) is different from a square with respect to its internal angles. Unlike a square, a non-square rhombus does not have all its internal angles equal to 90°. The number of lines of symmetry in a non-square rhombus is 2, whereas, a square has 4 lines of symmetry.
The required counterexample is rhombus for the given hypothesis "All parallelograms are rectangles" which is the correct answer would be option (B).
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
A rhombus that isn't square. In terms of internal angles, a non-square rhombus (also known as a rhombus) differs from a square. A non-square rhombus, unlike a square, does not have all of its internal angles equal to 90°. A non-square rhombus has two lines of symmetry, whereas a square has four lines of symmetry.
Therefore, the required counterexample is rhombus for the given hypothesis "All parallelograms are rectangles"

Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help
Answer:
The 2 numbers = 81 and 83
Step-by-step explanation:
As, one number = x
The other, because it's an even number and consecutive = x + 2
So the larger numbef here is x + 2
And they are saying 3 times x + 2 plus x = 330
So let's solve!
3 times x + 2 = 3(x+2) = 3x + 6
So we will add it to x = (3x + 6) +(x) = 4x + 6
So they are saying the sum of them will be 330
So, 4x + 6 = 330
4x = 330 - 6
4x = 324
x = 324/4
x = 81
So x is the first number = 81
And the second is x + 2 = 81 + 2 = 83
So the 2 numbers are 81, 83
Lets check!
3 times the bigger number = 83 x 3 = 249
We will add it to 81 and we will get 330
So, 249 + 81 = 330
So the answer is right
