Answer:
70
Step-by-step explanation:
Since 2:7 is the ratio of boys to girls, that would mean that there are 2 boys to every 7 girls. 2 x 10 is what gets us to 20 and for the ratio part for girls we have to do the same thing; 7 x 10. Now the ratio is 20:70. We can make sure that we are correct by multiplying. 2 can multiply 3.5 times until it gets to 7. So 20 x 3.5 is 70.
Answer:
33 ft²
Step-by-step explanation:
The formula for the surface area of a square pyramid is:
SA = b² + 2bs
Where b is the measure of the base and s is the slant height
Let's substitute into this equation:
SA = b² + 2bs
SA = 3² + 2(3)(4)
Solve:
SA = 3² + 2(3)(4)
Square 3:
SA = 3² + 2(3)(4)
SA = 9 + 2(3)(4)
Multiply:
SA = 9 + 2(3)(4)
SA = 9 + (6)(4)
SA = 9 + 24
Add:
SA = 9 + 24
SA = 33
Therefore, the surface area is 33 square feet.

7.log2 (x)=15.log2 (2)
log2 (x)^7=log2 (2)^15
x^7=2^15
(x^7)^1/7=(2^15)^1/7
x=2^15/7
