Zinaida [17]

The way i do it, is sort of like this :

Is 7 a factor of 42?
Is 5 a factor of 42?

7 is a factor of 42.
It must be in multiples of 7!

Therefore, we have 5 on the other side, which makes it 5 x 7 = 35

Fencing encloses a rectangular backyard that measures 300 feet by 600 feet. A blueprint of the backyard is drawn on the coordina

liubo4ka [24]

Answer:

$(x-15)^2+(y-30)^2=36$

Step-by-step explanation:

we know that

The dimensions of the rectangular backyard in the actual are 300 feet by 600 feet

The dimensions of the rectangular backyard in the blueprint are 30 units by 60 units

therefore

If the radius of the circular flower garden in the actual is 60 feet

then

the radius of the circular flower garden in the blueprint is 6 units

Find the center of the radius in the blueprint

Remember that the circular flower garden is in the center o the backyard

To find out the center, determine the midpoint of the rectangular backyard

C((0+30)/2,(0+60)/2)

C(15,30)

The equation of a circle in center radius form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center

r is the radius

we have

$(h,k)=(15,30)\\r=6\ units$

substitute

$(x-15)^2+(y-30)^2=6^2$

$(x-15)^2+(y-30)^2=36$

nikdorinn [45]

Since 19 is 76% of 25, we can assume that 76% of the people in the restaurant like the new menu. 76% of 227 is roughly 173. So about 173 people liked the menu that day. Hope this helps :)
