Answer:

The annual profits will be 2187.5

Step-by-step explanation:

p(x) = 65x - 0.3x^2

I am guessing that the 2 was supposed to be a square.

Simply plug in the number of pies sold:

p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

You deposit $200 in an account earning 3.5% simple interest how long will it take for the balance of the account to be $221

Rus_ich [418]

It takes 3 years for the balance of account to be $ 221

Solution:

From given information,

Principal = $ 200

Rate of interest = 3.5 %

Amount after "n" years = $ 221

To find: number of years

In simple Interest,

Simple interest = amount earned - principal

Simple interest = 221 - 200 = 21

Thus simple interest earned is $ 21

The formula for simple interest is given as:

$simple\ interest = \frac{ p \times n \times r}{100}$

Where,

p is the principal

n is the number of years

r is the rate of interest per annum

Substituting the given values in formula,

$21 = \frac{200 \times n \times 3.5}{100}\\\\21 = 2n \times 3.5\\\\n = \frac{21}{7}\\\\n = 3$

Thus it takes 3 years for the balance of account to be $ 221

Which postulate can be used to prove that the triangles are congruent?

Varvara68 [4.7K]

Haven't been taught this; but from what I searched up; I think the postulate for proving these shapes' congruence is Hypotenuse/Leg. I have no exact idea however. Correct me if I'm wrong :/

Answers please! I’m finding the volume and i don’t really get it

MrRa [10]

Answer:

V = 13/2

Step-by-step explanation:

When finding volume you must know the formula on doing so.

Volume = length × width × height

length = $2\frac{1}{2}$ --> $\frac{5}{2}$

width = $2\frac{1}{2}$ --> $\frac{5}{2}$

height = $3\frac{1}{4}$ --> $\frac{13}{4}$

mixed number --> fraction

$V = \frac{5}{2} x \frac{5}{2} x \frac{13}{4}$

$V = \frac{25}{4} x \frac{13}{4}$

$V = \frac{325}{8}$ or $\frac{13}{2}$
