Answer:
0.10
Step-by-step explanation:
0.10 = 10/100 or 10%
Multiply 400*0.10 to get 10% of 400.
Answer:
Step-by-step explanation:
<h3>Part i</h3>
<u>Jennifer's account:</u>
<u>William's account can be expressed as:</u>
Because the rate of change is 14 and y-intercept is 30
<u>They will be same after x years, f(x) = g(x)</u>
- 10x + 50 = 14x + 30
- 14x - 10x = 50 - 30
- 4x = 20
- x = 5
The accounts will be same after 5 weeks
<h3>Part ii</h3>
<u>The amount in the accounts after 5 weeks:</u>
- f(5) = g(5) = 10*5 + 50 = $100
Answer:
904.32 cubic ft
Step-by-step explanation:
To find the volume of a sphere, the formula is 
First, 3.14 * 4 for 12.56.
The radius is 6, and that cubed is 216.
After that, divide 216 by 3 for 72
Then, 12.56 times 72, which gets you the final answer of 904.32 cubic ft.
(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)
720 + 144 = 864
864 + 36 = 900
900 + 4.32 = 904.32
Answer:
The length of arc LMN is 14.2cm
Step-by-step explanation:
First of all we have to calculate the circumference of the circle and then extract the portion that corresponds to MN
To solve this exercise we need to use the circumference formula of a circle:
c = circumference
r = radius = 6cm
π = 3.14
c = 2π * r
we replace the known values
c = 2 * 3.14 * 6cm
c = 37.68cm
As we know a circle is represented with 360 ° and they tell us that the angle of the MN part is 75 °, so we have to know the relationship with respect to the total
75° / 360° = 5/24
Now we multiply this number by the circumference and we will obtain the length of the arc MN
MN = 37.68cm * 5/24
MN = 7.85cm
Now we add the values of LM with NM and we will obtain the length of LMN
LMN = 6.3cm + 7.85cm
LMN = 14.15cm
round to the nearest tenth
LMN = 14.15cm = 14.2cm
The length of arc LMN is 14.2cm
