Answer:
138.2
Step-by-step explanation:
use the formula 2(pi)radius (height)+2(pi)radius squared
can u mark my answer the branliest pliz
5:$2.50
9:?
divide 5 by both sides cause you wanna see how much is 1 liter so you can multiply that with 9.
5 divided by 5 is 1.
$2.50 divided by 5 is $0.50
1:$0.50
each liter costs $0.50
Multiply $0.50 with 9 and that is $4.50
the answer is $4.50
9x² - 6x + 1
1st method:
Factor 9, you will get 9( x² - 6/9 x+ 1/9). Or 9(x² -2/3 +1/9)
but 9(x² - 2/3 x + 1/9) this can be written as 9(x - 1/3)²
2nd method: Solve this quadratic equation by finding the zero values.
x' =[-b + √b² - 4ac] / 2a and x" = =[-b - √b² - 4ac] / 2a
a=9; b=-6; c=1, hence [6+√(36-(4)(9)]/2(9) = (6 - √0)/18 x = 6/18 = 1/3
even x" =1/3
and ax²+bx + c = a(x-x')(x-x") =9(x-1/3)²
Answer:
16.2 kilograms
Step-by-step explanation:
30 300-gram cans = 9000 grams of soup
18 400-gram cans = 7200 grams of vegetables
9000 + 7200 = 16200 grams
1000 grams = 1 kilogram
16200 / 1000 = 16.2 kilograms
and the answer is 4a + 5
Step-by-step explanation:
the value of a in the second is 1 so 3a + a is 4a
<h3>and 3 + 2 is 5 </h3>
