Bruce's dumbbells weigh 11 pounds each
Bruce has 14 dumbbells
we know that to calculate the total weigh of all the dumbbells we have to multiply weigh of each dumbbell with the total no of dumbbells
this is because by multiplying the no of dumbbells with weight of each one we get the altogether weight
so we will multiply weight of each dumbbell by total no. of dumbbells
by multiplying we get 14*11=156
therefore the altogether weight of dumbbells is 156 pounds.
Answer:
1 pear = $0.75; 1 orange = $0.65
Step-by-step explanation:
(1) 3P + 4O = 4.85
(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)
3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms
6O = 3.90 Divide each side by 6
O = $0.65 Substitute into Eqn (1)
3P + 4×0.65 = 4.85
3P + 2.60 = 4.85 Subtract 2.60 from each side
3P = 2.25 Divide each side by 3
P = $0.75
Oranges cost $0.65 each and pears are $0.75 each
Answer:
18.75 or 18 3/4 lbs
Step-by-step explanation:
We just have to multiply 11 1/4 and 1 2/3 to get the product, 18.75 or 18 3/4.
First we have to translate our fractions into decimals:
11.25 (11 1/4) and 1.166667 (1 2/3)
multiply:
11.25 x 1.166667 = 18.75
convert back to fraction:
18 3/4

49c^2 - 25d^6
(7c)^2 - (5d^3)^2
(7c + 5d^3)(7c - 5d^3)
The answer is: (7c + 5d^3)(7c - 5d^3).
Answer:
probability of blue ball is 1/2
probability of yellow ball is 1/4
Step-by-step explanation:
We have given 6 blue balls 3 green balls and 3 yellow balls
Total number of balls are: 12
we have to find the probability of choosing a blue ball:
Then the ball was placed in the bag since, it is given replacement
Now, we have to find probability of choosing a yellow ball
