Answer:

1.05833333 × 10-7 m/s

15 mph

Step-by-step explanation:

7.5+4.5=12

12 miles per 48 min

1.05833333 × 10-7 m/s

12/48 = 1/4

1/4 x 60 = 15

15 mph

Y-3=5(x-2) what are the intercepts t of x and y x=(_,_) y=(_,_)

yan [13]

$The\ x\ intercept\ is\ (\frac{7}{5}, 0)$

The y intercept is (0, -7)

Solution:

Given equation is:

y - 3 = 5(x - 2)

Find the x intercept

Substitute y = 0 in given equation

$0-3=5(x-2)\\\\-3=5x - 10\\\\5x = -3 + 10\\\\5x = 7\\\\x = \frac{7}{5}\\\\Thus\ the\ x\ intercept\ is\ (\frac{7}{5}, 0)$

Find the y intercept:

Substitute x = 0 in given equation

$y - 3 = 5(0-2)\\\\y - 3 = -10\\\\y = -10 + 3\\\\y = -7$

Thus the y intercept is (0, -7)

Which choice is equivalent to the product below when x > 0?

anastassius [24]

The product below is equivalent when x > 0 is 1/9

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:

$\\\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$

$\large \sf \dfrac{\sqrt{1} }{\sqrt{x^{2} } } \rightarrow \dfrac{1}{x}$

$\large \sf \dfrac{\sqrt{x^{2} } }{\sqrt{81 } } \rightarrow \dfrac{x}{9}\\\\$

Step two: rearranging the expression and canceling the common factors x, we will have,:

$\\\large \sf \dfrac{1}{\not x} \cdot \dfrac{\not x}{9}$

$\pink{\boxed{\large \sf \dfrac{1}{9} }}\\$

Therefore, the final answer to this multiplication will be 1/9.

A television costs $350 before sales tax is applied. The final cost of the television was $378.

lana [24]

To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800 /:350
x=108
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
