From 39 seconds to 13 seconds
O 53%
0 67%
057%
O 63%
Answer:
67%
Step-by-step explanation:
First of all, we must find the decrease;
39 - 13
=26
Then we can find the percentage decrease
26/13 ×100 =66.666..which can be written as 67.

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44
When using substitution, choose the best choice that describes a possible first step in solving
the following system of equations.
3x – 6y = -12
2x + y = 12
A. ADD (y) to both sides in the bottom equation
B. MULTIPLY the top equation by (-6)
C. SUBTRACT (2x) from both sides in the bottom equation
D. DIVIDE the top equation by (3)
E. SUBTRACT (-6y) to both sides of the top equation
Answer:
C. SUBTRACT (2x) from both sides in the bottom equation
Step-by-step explanation:
Given
[tex]3x - 6y = -12[/tex]
[tex]2x + y = 12[/tex]
Required
The first step of a substitution method
In the second equation, notice that the coefficient of y is 1.
So, the first step is to make y the subject of the formula.
This is achieved by subtracting 2x from both sides of the equation.
[tex]2x + y = 12[/tex]
[tex]2x - 2x + y = 12 - 2x[/tex]
[tex]y = 12 - 2x[/tex]
Hence: (c) is true

Write an equation for the graph, where
y
depends on
x
.
Answer:
y= -2x+4
Step-by-step explanation:
1) if they want an equation where y depends on x, then you need to write the equation in slope-intercept form. Or... y=mx+b where m is the slope and b in the y-intercept.
2) looking at the line, it intercepts y at 4, so that is your intercepts or "b"
3) the slope is the change in the y values over the change in the x values for any two points. Notice if you choose the point (0,4) and (2,0) the change in the y values is -4 and the change in the x values is 2. Therefore, the slope is -4/2 or -2. -2 is your m.
4) once you plug those values in to y=mx+b, you have y= -2x+4

Answer:
(245 / (6^2 - 1)) + 15 = 22
Step-by-step explanation:
Well we need to divide 245 by something - and by something that divides it, otherwise we can't solve this. It's not divisible by 6^2 = 36, it's not divisible by 6^2 - 1 + 15 = 50 and it's not divisible by 6^2 - (1 + 15) = 20. Our only option is (6^2 - 1) = 35
245/35 = 7 and we notice that 7 + 15 = 22, so we've solved it.

Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b

Let’s say that you have a square garden in your backyard. One side of the garden has a length of x + 4. Can you give an expression that we could use to represent the area of the garden?
Answer:
[tex]A=(x+4)^2\text{ or } A=x^2+8x+16[/tex]
Step-by-step explanation:
We have a square garden. One side of the garden has a length of (x + 4).
And we want to write an expression that could represent the area of the garden.
Remember that for a square, all sides have equivalent lengths. So, every side measures (x + 4). The area of a square is given by:
[tex]A=s^2[/tex]
Where s is the length of one side.
Substitute:
[tex]A=(x+4)^2[/tex]
Expand if desired. Hence, the expression for the area is:
[tex]A=x^2+8x+16[/tex]
