Answer:

h=43/2 = 21 1/2 = 21.5

Step-by-step explanation:

h−6.5=15

what is the length of the longest side of a triangle that has the vertices (2, 6), (-4, 6), and (-4, 4)? a. 2/10 units b. 40 uni
rewona [7]
Length (2, 6) to (-4, 6) is sqrt((x2 - x1))^2 + (y2 - y1)^2) = sqrt((-4 -2)^2 + (6 - 6)^2) = sqrt((-6)^2 + 0) = 6

Length (2, 6) to (-4, 4) is sqrt((-4 - 2)^2 + (4 - 6)^2) = sqrt((-6)^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40)  = 2sqrt(10) units

Length (-4, 6) to (-4, 4) is sqrt((-4 - (-4))^2 + (4 - 6)^2) = sqrt(0^2 + (-2)^2) = 2

Therefore, the length of the longest side is 2sqrt(10) units

The value of the expression
r-ruslan [8.4K]

Answer:

f(5) = 75

Step-by-step explanation:

The function is f(x) = 2x^2 + x(100 - 15x).

Evaluate this function at x = 5:  replace each instance of x with 5:

f(5) = 2(5)^2 + 5(100 - 15·5)

Order of operations rules require evaluating the expression enclosed in parentheses first.  We get:

f(5) = 2(5)^2 + 5(100 - 15·5)

      = 50       + (100 - 75), so that:

f(5) = 50 + 25 = 75

f(5) = 75

a recipe for sparkling grape juice calls for 1.5 quarts of sparkling water and 3/4 quart of grape juice. How much of each ingred
Naya [18.7K]

Answer:

33\dfrac{1}{3}\text{ quarts of grape juice}\\ \\66\dfrac{2}{3}\text{ quarts of sparkling water}

Step-by-step explanation:

A recipe for sparkling grape juice calls for 1.5 quarts of sparkling water and 3/4 quart of grape juice.

The ratio of sparkling water to grape juice is

1.5\div \dfrac{3}{4}=\dfrac{3}{2}\div \dfrac{3}{4}=\dfrac{6}{4}\div \dfrac{3}{4}=6\div 3=2\div 1

So, to make 100 quarts of punch you need x quarts of grape juice and 2x quarts of sparkling water.

Hence,

x+2x=100\\ \\3x=100\\ \\x=\dfrac{100}{3}=33\dfrac{1}{3}\text{ quarts of grape juice}\\ \\2x=66\dfrac{2}{3}\text{ quarts of sparkling water}

If the volume of a sphere is 576 pi cubic units what is the radius
Nesterboy [21]
If the volume of a sphere is 576 pi cubic units, then the radius is 7.56. I arrived to this answer through solving first what is 576 (<span>π) which led me to the answer 1808.64. Then I solved for the radius through deriving the formula of a volume of a sphere to finding the radius. Thus, the final ansewr is 7.56 units. </span>
