The simple interest formula is A = P(1 + r)t where P represents the amount originally deposited, r is the interest rate, and A i

s the amount in the account after t years.
Find r if A = 2700, P = 2200 and t = 5.
2700 = 2200(1 + r)5
Express r as a percentage to one decimal place (x.x%).

2700 = 2220 (1 + r ) 5


5 divided by 1 = 5

2220 divided by 5 = 440

2700 divided by 440 = 6.13%

15. A restaurant has one type of milk that has 2% fat and another that has 7% fat. how many quarts of each type does the restaur
krek1111 [17]
<span>B. 16 quarts of the 2% milk and 24 quarts of the 7% milk First, let's create an equation to solve. x = quarts of 2% milk (40-x) = quarts of 7% milk So we have the equation x*2 + (40-x)*7 = 40*5 Now to solve for x x*2 + (40-x)*7 = 40*5 x*2 + 7*40 - 7*x = 40*5 x*2 - 7*x = 40*5 - 7*40 -5*x = - 2*40 x = 2*8 x = 16 So we need 16 quarts of 2% milk and 40-16 = 24 quarts of 7%, which matches option "B".</span>

Use the formula to evaluate the series 1+2+4+8+...a10
valina [46]

Answer:

The sum of the given series is 1023

Step-by-step explanation:

Geometric series states that a series in which a constant ratio is obtained by multiplying the previous term.

Sum of the geometric series is given by:

S_n = \frac{a(1-r^n)}{1-r}

where a is the first term and n is the number of term.

Given the series: 1+2+4+8+.................+a_{10}

This is a geometric series with common ratio(r) = 2

We have to find the sum of the series for 10th term.

⇒ n = 10 and a = 1

then;

S_n = \frac{1(1-2^{10})}{1-2} =\frac{1-1024}{-1} =\frac{-1023}{-1}=1023

Therefore, the sum of the given series is 1023

A film student wants to capture a shot of a satellite dish placed at the top of a building. The line of sight between the ground
ICE Princess25 [194]

The ground, the building and the line of sight between the ground camera and the top of the building form right triangle with hypotenuse equal to 45 feet and angle adjacent to this hypotenuse and ground - 50°. The building is an opposite leg to the given angle, then you should write sine function:

\sin 50^{\circ}=\dfrac{height}{45} \\ \\ 0.766=\dfrac{height}{45}\\  \\ height=45\cdot 0.766=34.47.

The answer to the nearest tenth of a foot is 34.5 feet
