Answer:

the perimeter is 32sqrt(3) yd, or approximately 55.4 yd

Step-by-step explanation:

A square has 4 congruent sides, so if the length of 1 side is s, the perimeter is 4s. Also, the area of a square is the side squared, or A = s^2.

A = s^2

s^2 = 192 yd^2

Take the square root of both sides.

s = sqrt(192)

s = sqrt(64 * 3)

s = 8sqrt(3)

P = 4s

P = 4 * 8sqrt(3) = 32sqrt(3)

Answer: the perimeter is 32sqrt(3) yd, or approximately 55.4 yd

A cookie factory uses 1/6 of a bag of flour in each batch of cookies. The factory uses 5/6 of a bag of flour yesterday. How many
aliina [53]


From the information given, each batch of cookies requires 1/6 of a bag of flour.

So how many batches can be gotten from 5/6 of the bag of flour?

We form an equation

1batch  = 1/6

x batches = 5/6

Where x is the number of batches from 5/6 bag of flour.

Cross multiplying this equation we get:

x * 1/6 = 1 * 5/6

simplify it:

x * 0.16 = 1 * 0.83

x = 1 * 0.83 / 0.16

x = 0.83 / 0.16

x =  5.2

Therefore  factory made approximately 5 batches of cookies yesterday.

KonstantinChe [14]

Step-by-step explanation:

g(x)= -16x² + 72x + 80

Plug 2 in to check if it's correct.

g(2)= -16(2)² + 72(2) + 80

-16(4)+128+80

-72+128+80

= 136

Stolb23 [73]

Answer:

In the figure below :

d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°

Step-by-step explanation:

Side lengths :

2\cdot e=10\\ \Rightarrow e=5 feet\\\frac{d}{e}=\frac{5}{12}\\\Rightarrow d=\frac{25}{12}\approx 2.08 feet

By pythagoras theorem,

c^2=d^2+e^2\\c^2=29.33\\c\approx 5.42 feet

Now to find angles,

a+b+90^{\circ}=180^{\circ}\\\Rightarrow a+b=90^{\circ}\\\tan a=\frac{d}{e}\\\Rightarrow \tan a =0.42\\\Rightarrow a=22.78^{\circ}\\\Rightarrow b=67.22^{\circ}

At Roberta’s cafe half of her regular customers order her famous low-fat chicken sandwich. The probability of a regular customer
yuradex [85]

Answer:

The probability of losing weigth given that the sandwich was ordered is 80%.

Step-by-step explanation:

The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:

sandwich and losing weigh = (ordering sandwich)*losing weigth

losing weigth = (sandwich and losing weigth)/(ordeing sandwich)

losing wiegh = 40%/0.5 = 80%

The probability of losing weigth given that the sandwich was ordered is 80%.
