The radius of the shape is c. 3ft 3in
Answer:
42 hours
Step-by-step explanation:
Natalie needs to save a total of $479.58
She already saved $149.98
The amount left to save is
= 479.58-149.98
= 329.7
If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows
= 329.7 / 7.85
= 42
Hence Natalie will work for 42 hours to meet her goals
To compute the distance between the points, we can apply the distance formula as shown below.

In which x₁ and x₂ are the x-coordinates and y₁ and y₂ are the y-coordinates of the two points. Thus, applying this with the segments AABB, AACC, and BBCC, we have



Now that we have the lengths of all the sides of ΔAABBCC, we can find the missing angles using the Law of Cosines.
Generally, we have

or

Hence, we have



Simplifying this, we have


Thus, from this, we can arrange the angles from smallest to largest: ∠CC, ∠AA, and ∠BB.
Answer: ∠CC, ∠AA, and ∠BB
314 207 = 300 000 + 10 000 + 4 000 + 200 + 7
Answer:
Option (a) 45.31
Step-by-step explanation:
Data provided in the question:
Standard deviation, σ = 0.08 mm
Sample size, n = 30
standard deviation of 30 samples, s = 0.10
Now,
σ² = (0.08)² = 0.0064
s² = (0.10)² = 0.01
Test Statistic = [ ( n - 1) × s²] ÷ σ²
or
Test Statistic = [ (30 - 1 ) × 0.01 ] ÷ 0.0064
= ( 29 × 0.01 ) ÷ 0.0064
= 45.31
Hence,
Option (a) 45.31
