2x3y + 18xy − 10x2y − 90y

1 answer:

6 0

A. 2y is the GCF and you can tell that by it being the largest number that goes into all. Each term also has a y, but not all have an x.

2y(x^3 - 5x^2 + 9x - 45)

B. You can factor the remaining using the splitting method.

2y(x - 5)(x^2 + 9)

Answer:

Hence the correct answer is option (A) 4.708.

Step-by-step explanation:

Solution:-

Now, we need to find the angle of the sector by using sector formula,

$A = 28.25 ft^{2} \\r = 12ft.\\\\28.25 = \frac{\theta}{360^{o} } \times \pi \times 12^{2} \\\\\theta=\frac{28.25\times 360}{12 \times12 \times \pi} \\\\\theta =( \frac{70.625}{\\pi} )^{o}$

We now convert the angle to radian

$\theta = \frac{70.625}{\pi} \times \frac{\pi}{180}\\\\\theta = 0.39236 radian$

Now we calculate the length of arc by arc formula

$\theta=\frac{I}{12} \\\\0.39236 =\frac{I}{12}\\\\I = 4.708 feet.$

So, The length of steel that must be replaced is 4.708 ft.

(04.05) Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% mor

natali 33 [55]

Answer:

Evan is correct

Step-by-step explanation:

To find this answer, we can use the formula A=PxW

A=Part, P=Percentage, W=Whole

We can fill in the numbers we know and leave blank (with the variable) the numbers we want to find out

In this scenario, we want to find out if 25 is 125% of 29

So we can use this formula and do the equation like this:

A=1.25x20

This gets us to 25

So Evan is correct!

Hope this helps and please award brainliest if possible!
