Loga x=n ⇔ a^n=x
log₇ 21=x
x=log ₇ 21
x=ln 21 / ln7=1.564575034...
Answer: x=log₇ 21
Answer:
4.33
Step-by-step explanation:
1/3=0.33 recuring
4 just eqauls 4
so you add 0.3 recuring to 4
and depending on significant figures it wants you round it ill assume it wants 3 and go 4.33
Answer:
405
Step-by-step explanation:
We can use a ratio to solve
3 infected x infected
------------------ = ----------------
50 sampled 6750 population
Using cross products
3*6750 = 50x
Divide each side by 50
3*6750/50 = x

<span>he width is 5 feet and the length 10 feet
Let the width of the garden = W
Therefore the length = W + 5
The two sidewalks alongside the length are therefore W + 5 feet long by 2 feet wide = 2(W + 5) square feet each
The 2 sidewalks alongside the width = W feet long by 2 feet wide = 2W square feet each
In addition there are the 4 corners which are each 2 feet by 2 feet = 4 square feet each
Area of sidewalk is therefore
2 * lengths = 2 * 2(W + 5) = 4W + 20
2 * widths = 2 * 2W = 4W
4 corners = 4 * 4 = 16 square feet
But we are told that the area = 76 square feet
Therefore 4W + 20 + 4W + 16 = 76
8W + 36 = 76
8W = 40
W = 5
Therefore as the width is five feet the length is 5 + 5 = 10 feet</span><span>

Answer:
See the image below.
Step-by-step explanation:
The decimals 0.43 and 0.39 are equivalent to 43/100 and 39/100. These decimals lie between 0 and 1.
Draw a number line, mark off and label the multiples of 0.10(e.g 0.10, 0.20) in the interval 0-1.
Mark 0.43 between 0.4 and 0.5, a little closer to 0.4.
Mark 0.39 between 0.3 and 0.4, just behind 0.4.
Since 0.39 is smaller than 0.43( 0.39 lies on the left to 0.43), the inequality is:
0.39<0.43
