Answer to the following question is as follows;

Number of term in AP (N) = 10

Step-by-step explanation:

Given:

Sum of arithmetic progression (Sn) = 340

First term of AP (a) = 7

Common difference of AP (d) = 6

Find;

Number of term in AP (N)

Computation:

Sn = [n/2][2a + (n-1)d]

340 = [n/2][2(7) + (n-1)6]

340 = [n/2][14 + 6n - 6]

680 = n[6n + 8]

6n² + 8n - 680

Using Quadratic Formula

n = 10

Number of term in AP (N) = 10

David is filling a cylindrical cup with medication for his next patient. If he only fills the cup half way, what is the volume o
nignag [31]

Answer:

Volume of medication in the cup = 50.24 cubic inches

Step-by-step explanation:

Volume of the cylindrical cup = πr^2h

Radius, r = 2 inches

Height, h = 8 inches

Volume of the cylindrical cup = πr^2h

= 3.14 × 2^2 × 8

= 3.14 × 4 × 8

= 100.48

Volume of the cylindrical cup = 100.48 cubic inches

If David only fills the cup half way,

then, the volume of medication in the cup = Total volume of the cylinder / 2

= 100.48 inches / 2

= 50.24 cubic inches

volume of medication in the cup = 50.24 cubic inches

Step-by-step explanation:

7 to the power of 2 is 49 /  49+3 is 52  /  52-9 is 43  / 43x10 is 430

66 divided by 11 is 5 /  5 +3 is 8   /   8 X2 is 16

18 -3 is 15  /  15 + 3 is 18 /  18 to the power of 2 is 324  /   324 - 14 is 310

A chili recipe calls for 2 pounds of ground pork and 3.5 pounds of ground beef. The cost of ground beef per pound is $0.20 less
dmitriy555 [2]

Answer: \$1.75\ \text{per pound}

Step-by-step explanation:

Given

The recipe calls for 2 Pounds of ground pork and 3.5 pounds of ground beef

Suppose x is the cost of ground pork

So, the cost of ground beef is 2x-0.2

The total cost of meat is \$15.05

The total cost can also be written as

\Rightarrow 2\times x+3.5\times (2x-0.2)=15.05\\\Rightarrow 2x+7x-0.7=15.05\\\Rightarrow 9x=15.75\\\Rightarrow x=\frac{15.75}{9}=\$1.75\ \text{per pound}

So, the cost of ground pork is \$1.75\ \text{per pound}
