Answer:
$10t=m
Step-by-step explanation:
If for each hour is $10.
She would earn the number of hours times $10.
Example: She did babysitting for 4 hours this weekend. The equation is $10(4)=m or $10 x 4 = m. m=40
Answer:
gradient m is 2
Step-by-step explanation:
the equation is y=mx+c therefore m is 2.
Answer:
The area of sector is 7.48 unit²
Step-by-step explanation:
Given as :
The radius of circle = r = 3 unit
The measure of central angle =Ф = radian
Let The area of sector = A unit²
<u>Now, According to question</u>
Area of sector = π× radius × radius ×
Or, A = π× r × r ×
Or, A = π× r × r ×
where π = 3.14
∵ 180° = π radian
So, 360° = = 2 π radian
Or,, A = π× r × r ×
Or, A = π× r × r ×
Or, A = 3.14 × 3 unit × 3 unit ×
Or, A = 3.14 × 3 unit × 3 unit × 0.2647
∴ A = 7.48 unit²
So,The area of sector = A = 7.48 unit²
Hence, The area of sector is 7.48 unit² Answer
