Its 81 centimeters because you round 5 and over. So nearest centimeter means 2 whole numbers which is 81
Answer:
9*9
Step-by-step explanation:
Expanded form is writing out the exponent with multiplication.
9^3/9^1=9^2, or 9*9
Answer: inconsistent
Step-by-step explanation:
Inconsistent systems have two lines that are two independent equations that don’t overlap. Basically, if the lines are parallel, the system will always be inconsistent.
Answer & Step-by-step explanation:
If each fruit tree produces an average of 590 pounds of fruit, then that means we are going to multiply. For the apples, we are going to multiply 120 by 590. For the pears, we are going to multiply 90 by 590. After we multiply these numbers, we are going to add the products so we can find the total amount of pounds of fruit.
<u>Apples:</u>
120 × 590 = 70800
<u>Pears:</u>
90 × 590 = 53100
Now, we add 70800 to 53100.
70800 + 53100 = 123900
So, the orchard produces 123900 pounds of fruit in one year.
We're given pairs (A,B) and asked if we have
enough calcium,
5A + 4B >= 24
enough iron
4A + 6B >= 15
and enough vitamins
7A + 4B >= 15
We check each constraint on each pair; if we find any false we can stop for that pair.
(A,B)=(1,4)
5(1)+4(4)=21 under 24, NO CHECK
(A,B)=(1,5)
5(1) + 4(5) = 25, bigger than 24, good
4(1) + 6(5) = 34, bigger than 15, good
7(1) + 4(5) = 27, bigger than 15, good CHECK
(A,B)=(2,3)
5(2)+4(3)=22, NO CHECK
(A,B)=(3,2)
5(3)+4(2)=23, NO CHECK
(A,B)=(4,1)
5(4) + 4(1) = 24, ok
4(4) + 6(1) = 22, ok
7(4) + 4(1) = 32, ok, CHECK
