Answer:
4^3, 8^2, 2^6
Step-by-step explanation:
64^1 = 64
We need all expressions equal to 64.
4^3 = 4 * 4 * 4 = 64 Yes
3^4 = 3 * 3 * 3 * 3 = 81 No
8^2 = 8 * 8 = 64 Yes
2^8 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 256 No
6^2 = 6 * 6 = 36 No
2^6 = 2 * 2 * 2 * 2 * 2 * 2 = 64 Yes
Answer:
Tiffany has 13 dimes and 4 nickels.
Step-by-step explanation:
To solve this problem, you will need to write a systems of equations, n will be the number of nickels and d will be the number of dimes.
n+d=17 This means that the number of nickels plus the number of dimes is equal to 17.
5n+10d=150, This means that for each nickel, there is 5 cents and for each dime, there is 10 cents. The equation is equal to 150 cent because the coins are worth 150 cents.
Next, solve the system:
n+d=17
5n+10d=150 First simplify the second equation by dividing it all by 5.
n+d=17
n+2d=30, Next, isolate n to use substitution on the system.
n=17-d
n=30-2d, Substitute n to solve for d
17-d=30-2d, Solve for d
d=13, this means that there are 13 dimes, plug in the d value in either of the equations to find n.
n+(13)=17
n=4, There are 4 nickles
Roughly 2,365,200,000. If you have muiltiple choices round up to the nearest
Answer:
521, 400
Step-by-step explanation:
with the 1cm= 100m scale
6.6cm= 660m
7.9cm=790m
so the area would be 660×790
which is 521,400 meters squared
If you want the answer in point slope form then,
y-y1 = m(x-x1)
y-c = m(x-a)
---------------------------------------
If you want the answer in slope intercept form, then solve for y
y-c = m(x-a)
y-c = mx-ma
y-c+c = mx-ma+c
y = mx-ma+c
y = mx+c-ma
y = mx+(c-ma)
For this answer in slope intercept form the slope is m and the y intercept is c-ma
---------------------------------------
If you want the answer in standard form, then get the variable terms to the left side. Have the constant terms on the right side.
y = mx+c-ma
y-mx = mx+c-ma-mx
-mx+y = c-ma
Optionally you can multiply both sides by -1 to get mx-y = -c+ma but it will depend on your book if this step is carried out or not.
