Help with a geometry problem.

algol [13]

m∠E = 32, the first option.

If ∠F = 116 and all angles in a triangle must equal 180, then the other angles must add up to 64.

This rules out the third and fourth options. Logic then says that it can't be equal to 58. That wouldn't make sense. Also 64/2 = 32.

The sum of the squares of three consecutive integers is 194. What are the integers?

Grace [21]

Consecutive integers are 1 apart
they are
x,x+1,x+2
the sum of their squares is 194

x²+(x+1)²+(x+2)²=194
expand
x²+x²+2x+1+x²+4x+4=194
x²+x²+x²+2x+4x+1+4=194
3x²+6x+5=194
minus 5 from both sides
3x²+6x=189
3(x²+2x)=189
divide both sides by 3
x²+2x=63
minus 63 from bot sides
x²+2x-63=0
what 2 numbers multiply to get -63 and add to get 2
-7 and 9
(x-7)(x+9)=0
set each to zero

x-7=0
x=7

x+9=0
x=-9

for x=7
x+1=8
x+2=9

for x=-9
x+1=-8
x+2=-7

the integers are 7,8,9 or -9,-8,-7

Tamara purchased 1,500 shares of a mutual fund at an offer price of $7.08 per share. Later she sold the investment for $10.02 pe

den301095 [7]

Answer:

Return of investment = 44.5%

Step-by-step explanation:

Number of shares purchased by Tamara = 1500

Offer price per share = 7. 08

Total amount spent on purchasing shares = 1500 × 7.08 = 10620

Dividend receive per share = 0.21

Total dividend received on 1500 shares = no. of shares × dividend received per share

Total dividend received = 1500 × 0.21 = 315

Selling price per share = 10.02

Amount received by Tamara by selling the investment = no. of shares × selling price per share

Amount received by Tamara by selling the investment

= 1500 × 10.02

= 15030

Now, Net profit received on investment = S.P of Investment + Dividend received - C.P of investment

Net profit = 15030 + 315 - 10620 = 15345 - 10620 = 4725

Return on investment = $\frac{Net\ profit}{Cost\ of\ investment} \times 100$

= $\frac{4725}{10620} \times 100 = 44.49%$

≈ 44.5 %
