Kyle is determining any common multiple for 6 and 45. Which number could be the multiple?

zmey [24]

Answer:

C)90

Step-by-step explanation:

Common multiples are numbers that each number can be multiplied to make.

45 / 6 = 7.5 so, 45 is not an answer

45 does not go into 51

45 X 2 = 90 , 90 / 6 = 15

<u>90 can be an answer</u>

120/45 = 2.6666.... Not an answer

I know ask me how...

Lemur [1.5K]

I believe it's 2110. Because you have to multiply the numbers and then add the 2 numbers to get the final number. So 7 times 3 is 21
7 + 3 is 10
So I got 2110.

The bicycle wheel shown travels 63 inches in one complete rotation. If the wheel rotates only 120° about the center, how far doe

Cloud [144]

Answer:

21 inches

Step-by-step explanation:

In 1 rotation the angle at the centre = 360°

For 120° the fraction turned = $\frac{120}{360}$ = $\frac{1}{3}$ , thus

distance travelled = $\frac{1}{3}$ × 63 = 21 inches

Someone please help me??

The standard equation of a circle with centre (xc,yc) and radius R is given by

$(x-x_c)^2+(y-y_c)^2=R^2$

Substituting
centre (xc,yc) = (4,-3)
R=2.5

The equation is therefore

$(x-x_c)^2+(y-y_c)^2=R^2$
$(x-4)^2+(y-(-3))^2=2.5^2$
$(x-4)^2+(y+3)^2=2.5^2$ or
(x-4)^2+(y+3)^2=6.25
