Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

a) The interest generated over the 9 months is how much the woman paid for use of the money, then:

I=C.t.i\\C=3000\\t=9\\i=3.5%=0.035\\I=3000.9.0.035=945\\I=945

Therefore , the woman paid $945 for the use of the money.

b) The total amount that she repaid the bank is:

C_{t} =C+I=3000+945=3945\\C_{t} =3945

Finally we have that the woman paid $3945 to the bank

Find the surface area Sphere: area of the great circle ~ 28.6 in2
kari74 [83]
Area of a circle is πr².

Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>

Surface area of a sphere is 4πr².

4<span>π(3.017)</span>² = 114.4 to 1DP

2. The sum of the measures of angle X and angle Y is 90. If the measure of angle X is 30 less than (1 point)
Mariulka [41]

Answer: angle y is 50°

Step-by-step explanation:

t + 2t - 30 = 90

3t -30 = 90

3t = 90+30

t = 120/3 = 40 = angle X

Angle y = 2t-30

y = 2*40-30

=80-30 = 50
