Answer:
C = 50 + 30d
Step-by-step explanation:
For one day,
50 + 30
For two days
50 + 2(30)
For d days,
50 + d(30)
C = 50 + 30d
Do (6x12)/2, that should work
Answer:
It's right :)
Explanation:
- Dilation along the x-axis = (-7-1)/(-1-1) = 2/8 = 1/4
- Dilation along the y-axis = (-7-1)/(-1-1) = 2/8 = 1/4
Thus, the overall dilation is 1/4
Answer:
3.95 and -3.95
Step-by-step explanation:
To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so
x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.
He made his mistake in Step 2. Tom should have subtracted 4/8 instead of 1/8. The mistake is that he was not consistent when he multiplied Denominators (bottom number) must be the same when handling fractions so Tom must multiply both the numerator and denominator by the SAME number to balance it out. 1/2 x 4/4= 4/8. Subtract. 7/8 - 4/8= 3/8. Tom has 3/8 of a gallon of paint leftover.
