Answer:
8a^3
Step-by-step explanation:
Given that;
2^x = a, we want an expression for 8^(x + 1)
we have this as;
8^(x + 1) = 8^x * 8^1
8^x = (2^x)(3)
8^x is thus same as 2^3x
So replace 2^x by a
Thus, we have a^3
Multiply this by the 8 we had initially; that will give;
8 * a^3 = 8a^3
21/5.2
because in order to get mean you have to add all the numbers up and divide by the amount you added so 20+28+26+26+30+24+25+26+28+27= 210 divide by 10= 21
in order to get mad you take all the numbers and subtract them from the mean (what ever you get make sure the number is positive) so 21-20=1 28-21=7 and so on then add up the numbers and divide again to get 52 divide that by 10 and you get 5.2
because it is means to mad ratio the answer is 21/5.2
Answer:
12.5 in²
Step-by-step explanation:
Given:
Height of tile = 2.5 in
Base of tile = 2*height of tile = 2*2.5 = 5 in
Length of other side of tile = 2.5 in
Required:
Area of the tile
SOLUTION:
Area of the tile = area of parallelogram
All we need to calculate the area of the tile, is the base and the height.
Area of parallelogram = base × height
Area of tile = 5 × 2.5 = 12.5 in²
