Answer:

3.528

Step-by-step explanation:

First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.

Misty wishes to obtain 85 ounces of a 40% acid solution by combining a 72% acid solution with a 25% acid solution. How much of e

Y_Kistochka [10]

13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed

Step-by-step explanation:

Total mass of acid required= 85 ounces

Let the mass of 72% acid be 'a'

Let the mass of 25% acid be 'b'

a + b = 85

b = 85-a

85(40/100) = a(72/100) + b(25/100)

85(2/5) = a(72/100) +(85- a) (25/100)

34 = (72a/100) + (2125/100) - (25a/100)

34 - (2125/100) = (72a + 25a) /100

(3400-2125)/100 = 97a /100

97a = 1275

a = 13.15 ounces

b = 85 - 13.14

b = 71.85 ounces

13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed

ANSWER THIS CORRECTLY FOR BRAINLIEST!!!! This is 8th grade algebra btw

gulaghasi [49]

Answer:

V = 2143.57

Step-by-step explanation:

To find the volume of a sphere you need to use this formula:

$V = \frac{4}{3}\pi r^{3}$

r = radius

Solve:

You need the radius from the diameter. Divide 16/2 which is

$V = \frac{4}{3}(3.14) 8^{3}$

V = 2143.57
