Answer:
$11.76
Step-by-step explanation:
We first need to find the amount of plywood for all birdhouses.
2 3/5 * 8 = 104/5 or 20.8 or 20 4/5
Now we can solve the cost for all the birdhouses by multiplying the total amount of plywood needed by the price per square foot.
20.8 * 0.56 = $11.648 or estimated $11.65
Remember, the question might be different, so don't submit anything yet. If the people who sell the plywood only sell in integer numbers (meaning you can't buy 4/5 of a square foot of wood but can only by amounts with no fractions), then Jenna must buy 21 square feet of plywood and will have a little bit of wood left over. Now solve just like before.
21 * 0.56 = $11.76
Therefore the answer is $11.76 if she can only buy an integer amount of plywood or estimated $11.65. I think the best answer is 11.76.

Two trains, Train A and Train B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each train?
Answer: A = 317
B = 61
Step-by-step explanation:
The following equation can be gotten from the question given. This will be:
A + B = 379 ........ i
A - B = 255 ........ ii
From equation i, make A the subject of the formula
A = 379 - B ...... iii
Put the value of A in iii into equation ii
A - B = 255
(379 - B) - B = 255
379 - B - B = 255
379 - 2B = 255
2B = 379-255
2B = 124
B = 124/2
B = 62 tons
Since A + B = 379
A + 62 = 379
A = 379 - 62
A = 317 tons

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

How long does it need to keep $600 in an account that pays 2.75% annual simple interest to earn $264?
Answer:
16 years

Rate of interest (R) = 2.75%
Simple interest (S.I.) = $264
Let t denotes time period.
[tex]S.I.=\frac{PRT}{100}[/tex]
[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]

A field is in the form of a rhombus having each side 81 m and altitude 25 m. What is the side of a square
field which has the same area as that of the rhombus?
Answer:
the side of a square is 45 m
Step-by-step explanation:
The computation of the side of the square field that contains the similar area as compared with rhombus is given below:
As we know that
Area of rhombus = Base × Altitude
= 81 × 25
= 2025
And, area of Square = Side × side
2025 = side^2
side = √2025
= 45m
Hence, the side of a square is 45 m
Tell whether the equation has one, zero, or infinitely many solutions.9(x − 3) + 15 = 9x − 11.
Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9
No solution
