Answer:

Step-by-step explanation:

Because we know that 1 side is 12, we can multiply it by 2 to find part of the perimeter, which is 24. Now we know that the other 2 sides add up to 12. That means that they each measure 6, so x = 3. The real question is why it shows that 6 is longer than 12!

A triangle has the coordinates of A (1,2), B (4,6), and C (4,-3). If the triangle is translated 2 units right, what are the new

yaroslaw [1]

A'(3, 2 ), B'(6, 6 ),C'(6, - 3 )

A translation of 2 units right is equivalent to adding 2 to the x- coordinate with no change to the y- coordinate.

A(1, 2 ) → A'(1 + 2, 2 ) → A'(3, 2 )

B(4, 6 ) → B'( 4 + 2, 6 ) → B'(6, 6 )

C(4, - 3 ) → B'(4 + 2, - 3 ) → B'(6, - 3 )

How do I convert 75 feet/second to miles/hour rounding to the nearest whole number

MAVERICK [17]

Answer:

51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

Step-by-step explanation:

Given:

75 feet/second.

Now, to convert 75 feet/second into miles/hour.

So, to convert we divide the value of feet per second by conversion factor to get miles per hour.

Value of feet per second = 75.

Conversion factor = 1.4667.

Now, putting the formula to get the value in miles/hour:

Value in miles/hour = value of feet/second ÷ conversion factor.

Value in miles/hour = $75\div 1.4667.$

= $51.135\ miles/hour.$

<em>Rounding nearest to whole number = 51 miles/hour.</em>

Therefore, 51 miles/hour is the conversion of 75 feet/second rounding to nearest whole number.

If a vertical pole 30 ft tall casts a shadow 8ft long, how long would the shadow of 40-ft pole be at the same time and place

TEA [102]

Since it as at the same time and place.

Let x be the length of the shadow of the 40-ft pole.

The ratio from 30 and 8 would have to be the same as 40 and x.

30:8 = 40:x

30/8 = 40/x Cross multiply

30x = 40*8

x = 40*8 / 30 = 32/3 = 10.67

Length of shadow for 40ft is 10.67 ft.
