A tortoise walks 52 ft per hour. Convert this speed into inches per minute

1 answer:

7 0

First multiply 52 by 12 to get inches per hour. 624 in per hour. Then make it 624 inches in 60 minutes. Divide 624 by 60 to get 10.4. So it's speed in inches per minute is 10.4 in per min.

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Please Help ASAP I dont understand this <br><br>

antiseptic1488 [7]

To find m<3, we can use the angle sum of triangles, in which the addition all angles in a triangle must be equal to 180°.

In this case:

m<3 +52°+29° = 180°

m<3 + 81° = 180°

m<3 = 180°-81°

m<3 = 99°

To find m<4, we can use adjacent angles on a straight line, where the addition of angles on a straight line must be 180°.

In this case:

m<4 + 99° = 180°

m<4 = 180°-99°

m<4 = 81°

Therefore m<3 is 99° while m<4 is 81°.

Hope it helps!

Question 10

Bond [772]

Answer:

( x - 2)^2 + ( y - 3)^2 = 34

Step-by-step explanation:

The equation of the circle with a center and a point

( x - a) ^2 + ( y - b) ^2 = r^2

( a, b) - the center of the circle

( x, y) - any point on the circle

r^2 - radius of the circle

( -3 , 6) - point - ( x, y)

x = -3

y = 6

( 2 , 3) - center-( a, b)

a = 2

b = 3

Step 1: substitute the center into the equation

( x - 2)^2 + ( y - 3)^2 = r^2

Step 2: sub the point into the equation

( x - 2)^2 + ( y - 3)^2 = r^2

( -3 - 2)^2 + ( 6 - 3)^2 = r^2

( -5)^2 + 3^2 = r^2

25 + 9 = r^2

34 = r^2

Step 3: sub the radius into the equation

( x - 2)^2 + ( y - 3)^2 = r^2

( x - 2)^2 + ( y - 3)^2 = 34

Therefore, the equation of the circle is

( x - 2)^2 + ( y - 3)^2 = 34

Find the nonpermissible replacement for a in this expression 6/-5a

Mademuasel [1]

Find the nonpermissible replacement for a in this expression 6/-5a

Denominator cannot be zero or else undefined so set the denominator to zero and solve for the a that will cause the denominator to be zero.
-5a=0
-5/-5x=0/-5
x=0

Nonpermissable replacement is 0.
