Answer:

15.56 ft

Step-by-step explanation:

The formula for the area of a triangle is

A = ½bh

This is an isosceles triangle, so b = h.

Substitute the value of h

A = ½b² = 121

Multiply each side by 2

b² = 242

Take the square root of each side of the equation.

b = √242 ≈15.56 ft

The length of the two equal sides of the triangle is approximately 15.56 ft.

<em>Check: </em>

A = ½(15.56)² = ½× 242 = 121 ft²

Answer:

25 ounces of Lemonade concentrate.

Step-by-step explanation:

Here is the complete question: Judy use 5 ounces of lemonade concentrate for every 9 ounce of orange juice. If f Judy used 45 ounces of orange juice concentrate to make the fruit punch how many ounces of lemonade concentrate does she use?

Given ratio that Judy use is 5 ounces of lemonade concentrate to 9 ounces of orange juice.

∴ ratio for lemonade concentrate to orange juice= $\frac{5}{9}$

Now finding proportion of lemonade concentrate, if judy use 45 ounces of orange juice to make fruit punch.

$\frac{Lemonade\ concentrate}{orange\ juice} = \frac{5\ ounces}{9\ ounces} = \frac{Lemonade\ concentrate}{45\ ounces}$

Cross multiplying both side.

∴ Lemonade concentrate required = $\frac{5}{9} \times 45= 25\ ounces$

Hence, Judy require 25 ounces of Lemonade to make fruit puch if she use 45 ounces of orange juice.

Suppose the radius of a sphere is tripled.

Nimfa-mama [501]

$A=4r^2\pi
\\r_1=4r
\\A_1=4r_1^2\pi=4(4r)^2\pi=4\times16r^2\pi=16\times4r^2\pi=16A$
The surface area is increased 16 times.

$V= \frac{4}{3} r^3\pi
\\
\\r_1=4r
\\
\\V_1=\frac{4}{3} r_1^3\pi=\frac{4}{3} (4r)^3\pi=\frac{4}{3} \times64r^3\pi=64\times\frac{4}{3} r^3\pi=64V$
The volume is increased 64 times.
