Hi there! The answer is 80 green apples.
In a bag of apples, the ratio of red apples to green apples is 3:4, so we must first realise that there is a total of 7 parts.
3 of these parts constist if red apples. In other terms 3 / 7 equals 60. Now divide by 3 to find 1 / 7. Hence, 1 / 7 equals 60 / 3 = 20 apples.
4 of the total 7 parts consist of green apples, so we must multiply the preceding outcome by 4 to find our answer. 4 / 7 equals 20 × 4 = 80 apples.
Therefore, there are 80 green apples in the bag.
~ Hope this helps you!
Answer:
Step-by-step explanation:
Given the area of the base of the oblique pentagonal pyramid is 
and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6 cm
Now, volume of pyramid
Area of the base=50 cm²
so, 
Answer:
2x+6
Step-by-step explanation:
Answer:
It could be 2:5 or 6pi:15pi
Step-by-step explanation:
If you write the ratio of the surface area as a fraction, you would get 
. Simplifying it would leave 
. But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is 
. The answers would be 2:5 and 6pi:15pi.
