Answer:
0.00094
Step-by-step explanation:
Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:
- Use a positive exponent for large numbers greater than 1.
- Use a negative exponent for small numbers less than 1.
- Always write the first number as a value between 0 and 9.
9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is -4, this means 0.00094 is the solution.
56 /2 = 28
35^2 - 28^2
= 1225 - 784
= 441
= 21
base of triangle = 21 x 2 = 42
area of triangle = 1/2 bh = 1/2(42)(28) = 558
area of rhombus = 558 x 2 = 1176
answer
B . 1176 in^2
Answer:
9
Step-by-step explanation:
If you put 378 into 42 groups there is 9 pieces of candy in each group. So therefore that answer is 9.
We will use the following coordinates (4,4) and (5.5,3.5) these two are closest to the line.
Then we will do the following to find the gradient (slope)
(3.5-4)/(5.5-4) = - 1/3
rounded to 3 decimal places would give us -0.333
D I hope this helps :) :)
