Answer:
7. m<K = 60
8. m<U = 110
9. m<C = 50
Step-by-step explanation:
Triangles: when all 3 angles all added it should be 180 degrees
7. 60+60+unknown value=180 --> unknown value=180-60-60=60
8. 35+35+unknown value=180 --> unknown value=180-35-35=110
9. 53+77+unknown value=180 --> unknown value=180-53-77=50

Answer:
1. = 3.143
2. Circumference
3. Area of the circle is 3850 .
ii. Circumference of the circle is 220 cm.
Step-by-step explanation:
The area, A, and the circumference, c, of a circle can be determined respectively by:
A =
C = 2r
where r is the radius of the circle.
1. the ratio of the circumference and diameter, D, of a circle is:
r =
so that,
C = 2
C = D
=
=
= 3.143
2. The distance around a circular region is known as it's circumference.
3. Given a circle of radius 35 cm, then:
A =
= x
= x 1225
= 22 x 175
A = 3850
Area of the circle is 3850 .
C = 2r
= 2 x x 35
= 2 x 22 x 5
= 220
C = 220 cm
Circumference of the circle is 220 cm.
To find Marias salary we have to multiply working hours by 8.76$. We know that she works 24.5 per week so lets multiply it
24.5*8.76=214.62$ - Maria's salary
Answer:
<em>The interest earned is $302.18</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when the interest is reinvested rather than paying it out. Interest in the next compound period is earned on the principal sum plus previously accumulated interest.
The formula is:
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The investment described in the question is of P=$600 at a rate of r=6%=0.06 for t=7 years compounded annually. The compounding period coincides with the time of interest rate, thus n=1.
Applying the formula:
A = $902.18
The interest is:
I = A - P = $902.18 - $600 = $302.18
The interest earned is $302.18
