Answer:
174 packages of t-shirts PLEASE GIVE BRAINLIEST
Step-by-step explanation:
139 x 5 = 695 t-shirts are needed
695 ÷ 4 = 173.75
Since you have to purchase whole packages of t-shirts you will need to buy 174 packages of t-shirts. 174 x 4 = 696 t-shirts
174 packages
Answer:
16
Step-by-step explanation:
Write the expression in algebraic form:
3x² + 4y²
Notice we only have variables "x" and "y".
Given these variables: x = 2, y = 1, and z = –3
We can <u>ignore "z"</u> because the variable is not in the equation.
<u>Substitute</u> x = 2 and y = 1 in the expression. In other words, replace "x" and "y" with the numbers they give you.
3x² + 4y²
= 3(2)² + 4(1)²
Then, simplify the expression. Remember to follow <u>BEDMAS order</u> (brackets, <u>exponents</u>, division and <u>multiplication</u>, <u>addition</u> and subtraction).
= 3(2)² + 4(1)² Solve exponents first
= 3(4) + 4(1) Solve multiplication
= 12 + 4 Solve addition
= 16 Answer
The value of 3 x squared plus 4 y squared is 16, if x = 2, y = 1, and z = -3.
Answer:
This is a pretty broad question but im guessing you could use math to calculate how many people would get infected each day. You could start with
Ex.
Okay if we have one infected person how many people could they possibly pass the illness onto the next day. Well if they have x number of classes and see y number of people in those classes whats the PROBABILIITY one of those people gets the virus. Than you could calculate how many people will get infected the NEXT day.
