Hi there!
<u>Here are all the steps into solving this equation :</u>
<u>- 8</u> = 5.4
Add 8 on each side of the equation → 5.4 + 8 = 13.4
= 13.4
Multiply each side of the equation by 5 → 13.4 × 5 = 67
9z <u>+ 4</u> = 67
Subtract 4 from each side of the equation → 67 - 4 = 63
<u>9</u>z = 63
Divide each side of the equation by 9 → 63 ÷ 9 = 7
z = 7
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
78 degrees
Step-by-step explanation:
If you look at it, 2 of the angels are the same- those angels are A and B- the angel we are looking for. Angel A is 78 degrees and if angel A and angel B are equal then angel B is also 78 degrees.
The poopulation exponential model is given by

Where, P(t) is the population after year t; Po is the initial population, t is the number of years from the starting year; k is the groth constant.
Given that the population in 1750 is 790 and the population in 1800 is 970, we obtain the population exponential equation as follows:

Thus, the exponential equation using the 1750 and the 1800 population values is

The population of 1900 using the 1750 and the 1800 population values is given by

The population of 1950 using the 1750 and the 1800 population values is given by

From the table, it can be seen that the actual figure is greater than the exponential model values.
Answer:
4
Step-by-step explanation:
If the tape is 12m,
she hung the tape in between every 3m, and at both ends
0, 3, 6, 9, 12
these are the lengths she hung ribbons at
Total number of ribbons = 4
