HELP ASAP. Teacher didnt teach us this.

Mathematics
1 answer:
mina [271]3 years ago
5 0

Answer:

A = 624

B = 14.76 or 14.8 or 15inches

Standard form in polynomial for Area = 26 x 24 = .624in^2.....

2(5 + 8) x 2( 5 + 7)

26 x 24 = 624 in^2

This is because the rectangle width indifference is 1/10th of the length measuring 2inches more, then we see both sides of the frame are equal to 2inches and match this measure for x = 2inches both width and length. We add 4 to each side 22 x 20 + 4x^2 we separate 4x^2 into 4x both sides, this has become 26 x 24 = 624in^2

as 4 was added each side.

Question 2.  

We find the width is shown left to right in rectangles, they are the sides.

So Area 4 x 24 = 96in^2

or 6.5 of the 24 = 24/6.5 = 3.69 inches

26 /6.5 = scale of 6.5: 26 = 4 inches

Therefore Area = 3.69 x 4 = 14.76

if it was square frame it would be 16inches

Go for 14.76in^2 as ithe question says 4 inches and it becomes, a replaced width only and it must be still to scale as shown above with 24/6.5 = 3.69  so 3,69 x 4 = 14.76. Last resort would be that the length as kept at 24 x 4 = 96 and in this response it does exactly what the question asks the width changes only.

8. The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to buy a new boat
Natali [406]
Answer: the speed of the boat on the lake is 9 mph
Step-by-step explanation:
Let x represent the speed of the boat on the lake or in still water.
The speed of the current in a river is 6 mph. This means that if the boat goes upstream against the speed of the current, its total speed would be (x - 6)mph. If the boat goes downstream against the speed of the current, its total speed would be (x + 6)mph.
Time = distance/ speed
Every day, his route takes him 22.5 miles each way against the current and back to his dock, and he needs to make this trip in a total of 9 hours. This means that the time taken to travel upstream is
22.5/(x - 6). The time taken to travel downstream is
22.5/(x + 6)
Since the total time is 9 hours, it means that
22.5/(x - 6) = 22.5/(x + 6)
Cross multiplying, it becomes
22.5(x + 6) + 22.5(x - 6) = 9
Multiplying through by (x + 6)(x - 6), it becomes
22.5(x - 6) + 22.5(x + 6) = 9[(x + 6)(x - 6)]
22.5x - 135 + 22.5x + 135 = 9(x² - 6x + 6x - 36)
22.5x + 22.5x = 9x² - 324
9x² - 45x - 324 = 0
Dividing through by 9, it becomes
x² - 5x - 36 = 0
x² + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = - 4
Since the speed cannot be negative, then x = 9

The 5 horses on Miranda's farm each eat 20 pounds of feed per day . How many tons of feed do the horses in in 30 days
satela [25.4K]

Answer:

1.5 tons

Step-by-step explanation:

First determine how much feed is eaten per day

5 * 20 lbs = 100 lbs per day

Then multiply by the number of days

30 * 100 = 3000 lbs

But the question asks tons, not lbs

We know there are 2000 lbs in a ton

3000lbs/ 2000lbs per ton = 1.5 tons
