How many teaspoons of brine shrimp every day? There are about 125,000 Brine shrimp in 1 pound. A pound contains 96 teaspoons. A

sveticcg [70]

Answer:

$2\frac{38}{125}\ teaspoons$

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

so

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

$\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons$

Simplify

$\frac{288}{125}\ teaspoons$

Convert to mixed number

$\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons$

find all integers x satisfying each of the following congruences mod n. if no such x exists, explain why not

zalisa [80]

Answer:

please find the solution:

Step-by-step explanation:

please find the correct question:

Given value:

$\to 4x \equiv 2(mod\ n) \ \ \ \ \ \ \ \ \ \ \ \ _{where} \ \ n=6\\\\\to 4x \equiv 2 (mod 6)$

$\to 4x-2$ should be divisible by 6 we are also given that $0 \leq x < n$ and start with x = 0

$\to 4x-2$ =-2 which is not divisible by 6

x= 1

$\to 4x-2$ = 2 not divisilble by 6

x= 2

$\to 4x-2$ = 6 which is divisible by 6

x=3

$\to 4x-2$ = 10 not divisible by 6

x=4

$\to 4x-2$ = 14 not divisible by 6

x=5

$\to 4x-2$ = 18 which is divisible by 6

so such x are x = 2 and x = 5

You have a credit card balance of %188, and you pay annual interest on the unpaid balance of 18%. If you pay $50 on your balance

GaryK [48]

$27.79. First multiply the percentage as a decimal out of 100. Subtract that number from the original amount. Do the same thing with the number you got from subtracting(multiply by percentage then subtract from starting amount(the new one)) you end up with $27.79
