Answer:
x = 12
y = 9
z = 11
Step-by-step explanation:
so, let's just do all the calculations in there :
(3×5)⁴ = 3⁴×5⁴
(2×3)⁵ = 2⁵×3⁵
(2×5)⁷ = 2⁷×5⁷
multiplying all 3 terms is then
3⁴×5⁴×2⁵×3⁵×2⁷×5⁷
more let's "group" and combine these terms based on the bases of the power operations, as we need to get an expression showing 2, 3 and 5 with their powers.
so, for the base of 2 we have
2⁵×2⁷ = 2¹²
for the base of 3 we have
3⁴×3⁵ = 3⁹
fire the base of 5 we have
5⁴×5⁷ = 5¹¹
so we get
2¹² × 3⁹ × 5¹¹
=>
x=12
y=9
z=11
Answer: y=2
Step-by-step explanation:
This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A = 
A = 
= 15 * 18
= 270
Answer: 270 cm²
Answer:
750
Step-by-step explanation:
The big showroom has an area of 0.25 million sq. ft.
In the last summer sale, it is surveyed that the population density was 0.003 people per sq. feet and that included all the people in the building.
Therefore, the number of people who attended the summer sale at this showroom on that day was (0.003 × 0.25 × 1000000) = 750. (Answer)
{Since 1 million = 1000000}
If she needs 8 cups of flower for 4 eggs, when you could change that to needing 4 cups of flower for 2 eggs, now we know every 4 cups of flower is 2 eggs, and we already know 8 cups of flower is 4 eggs, so if we add 2 more eggs and that means 4 more cups of flower, the final answer is: 12 cups of flour is 6 eggs. To make it easier to remember, just remember if you have even numbers you can split them into pieces and just add those pieces over and over until you get it. We started with 8 cups of flour is four eggs, and if you put it to its smallest part It would be 4 cups of flower for 2 eggs, then you just have to remember how to count your 4’s and 2’s and it’s as easy as that
