Answer:

B: The mean wingspan is 59 inches.

Step-by-step explanation:

The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.

kaheart [24]
V=hpir^2
r=10
v=6283

6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches

*ANSWER FAST* x-1/x-2 + x-3/x-4 = 3 1/3 [x≠2 , x≠4] find
Natali5045456 [20]

Answer:

x = 5, x = \frac{5}{2}

Step-by-step explanation:

Given

\frac{x-1}{x-2} + \frac{x-3}{x-4} = 3 \frac{1}{3}

\frac{(x-1)(x-4)+(x-3)(x-2)}{(x-2)(x-4)} = \frac{10}{3}

\frac{x^2-5x+4+x^2-5x+6}{x^2-6x+8} = \frac{10}{3}

\frac{2x^2-10x+10}{x^2-6x+8} = \frac{10}{3}  ( cross- multiply )

10(x² - 6x + 8) = 3(2x² - 10x + 10) ← distribute both sides

10x² - 60x + 80 = 6x² - 30x + 30 ← subtract 6x² - 30x + 30 from both sides

4x² - 30x + 50 = 0 ( divide through by 2 )

2x² - 15x + 25 = 0 ← in standard form

(2x - 5)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

2x - 5 = 0 ⇒ 2x = 5 ⇒ x = \frac{5}{2}

x - 5 = 0 ⇒ x = 5

a nutritionist finds that meal A has more fat than meal B. Meal A has 5 grams more than 6 times the amount of fat that meal B ha
WARRIOR [948]

Answer:

A has 77 grams and B has 12 grams.

Step-by-step explanation:

In order to find the amount of fat in both, we need to set up two equations in standard form. First, we can set up one comparing the two amounts and solve for the constant.

A = 6B + 5

A - 6B = 5

Now we can create one using the difference of the two.

A - B = 65

To solve, we now multiply the second equation by -1 and solve for B.

A - 6B = 5

-A + B = -65

----------------

-5B = -60

B = 12

Knowing this we can plug into the equation and find the value of A.

A - B = 65

A - 12 = 65

A = 77
