Answer:
<h3>
m∠A = 46°</h3>
Step-by-step explanation:
∠A and∠B being complementary means m∠A+m∠B=90°
m∠A = (4x+6)° and m∠B = (4x+4)°
so:
4x+6 + 4x+4 = 90
8x + 10 = 90
8x = 80
x = 10
m∠A = (4•10+6)° = 46°
Answer:
Step-by-step explanation:
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = 2
r = 14/2 = 7
To find T7,
n = 7
T7 = 2 × 7^(7 - 1)
T7 = 2 × 7^6
T7 = 235298
To find T20,
n = 20
T20 = 2 × 7^(20 - 1)
T7 = 2 × 7^19
T7 = 22797790370746286
It takes 8 dozens of flour.
5x4=20 so the person needs 4 times more than 2 dozens. 2x4=8 therefor, the person needs 8 dozens of flour.
