Answer:

  • Fran is 12, Nancy is 4

Step-by-step explanation:

Let Fran - f and Nancy - n

<u>The ages at present:</u>

  • f = 3n

<u>In four years:</u>

  • f + 4 = 2(n + 4)

<u>Simplify and substitute f:</u>

  • f + 4 = 2n + 8
  • f = 2n + 4
  • 3n = 2n + 4
  • n = 4

<u>Find f:</u>

  • f = 3*4 = 12

Find the distance from A to C across the gorge illustrated in the figure
emmasim [6.3K]

Applying the tangent ratio, the distance from A to C across the gorge, is:  60.6 ft.

<h3>What is Tangent Ratio?</h3>

The tangent ratio for solving a right triangle is given as, tan ∅ = opposite/adjacent.

Given the following:

  • ∅ = 25°
  • Adjacent length = 130 ft
  • Opposite length = AC

Apply the tangent ratio:

tan 25 = AC/130

AC = (130)(tan 25)

AC = 60.6 ft

Solve the simultaneous equations<br><br> 3x + 2y = 30<br> 3x - y = 21
Mrac [35]

Answer:

x = 8 , y = 3

Step-by-step explanation:

3x + 2y = 30

3x - y = 21      -> y = 3x - 21

3x + 2 (3x - 21) = 30

3x + 6x - 42 = 30

3x + 6x = 30 + 42

9x = 72

x = 72/9 = 8

y = 3*8 - 21 = 24 - 21 = 3

∴ x = 8 & y = 3

PLEASE HELP ASAP THX SM (;
rjkz [21]

Answer:

558 cm^3

Step-by-step explanation:

V cone = 1/3 pi r^2 h

We know it is  186 cm^3

186 =1/3 pi r^2 h

Multiply by 3

558 = pi r^2 h


V cylinder = pi r^2 h

From above we know that pi r^2 h is 558 , so the Volume of  the cylinder is 558 cm^3
