Answer:
choice A) circumference = 31.4 ft
Step-by-step explanation:
circumference = 3.14(10)
circumference = 31.4 ft
Answer: 1/8 is left over.
Step-by-step explanation:
Tess already at half of the pizza, and Shawn ate a quarter of the pizza.
1/2 + 1/4= 3/4
There is a quarter of pizza remaining, but Molly ate half of that quarter (1/8). There is only 1/8 of pizza left.
Answer:
x = 50
Step-by-step explanation:
Since the output is 0, x^2 is 2500 but written differently.
Just take the square root of 2500, which is 50.
50^2 = 2500
2500 - 2500 = 0
3.5 × 10 = 35.0
The mistake is that you only added a zero to the answer (3.5 -> 3.50), but you forgot to replace the point in your answer (because 3.50 is wrong and 35.0 is correct). Hence, you should have replaced to point, by moving it one spot to the right.
Answer:
x=(5+i*sqrt(35))/2, (5-i*sqrt(35))/2
Step-by-step explanation:
Use the quadratic formula with the following values.
a = 1
b = -5
c = 15
Substitute and simplify.
(5+-sqrt((-5)^2-4*(1*15)))/2*1
x = (5+-i*sqrt(35))/2
When you get a negative number inside the square root, remember that you can pull out i to make the number inside positive.
