Hello!
50 - 40%
x - 100%
50 x 100 = 40x
40x = 5000
x = 125
Answer: Searched Number is 125.
50 is 40% of 125.
Hope this Helps! Have A Wonderful Day! :)
Since it is an isosceles triangle, the two angles across from the two equal sides must be equal. Therefore, 8y-7=73 so 8y=80 so y=10.
So, each of those to base angles is 73°. If you add them together those two angles equal 146°. Since there are 180° in a triangle, 180-146 equals 34 degrees.
So 6x+4=34 so 6x=30 so x=5.
Answer:a line graph would show the data over time.I would plot the days along the horizontal axis and each daily profit at points on the vertical axis.I would connect the points with lines.If her profit increasing each day, I would expect the line height to increase over time.

Answer:
It would take 5.9 years to the nearest tenth of a year
Step-by-step explanation:
The formula of the compound continuously interest is A = P , where
- A is the value of the account in t years
- P is the principal initially invested
- e is the base of a natural logarithm
- r is the rate of interest in decimal
∵ Serenity invested $2,400 in an account
∴ P = 2400
∵ The account paying an interest rate of 3.4%, compounded continuously
∴ r = 3.4% ⇒ divide it by 100 to change it to decimal
∴ r = 3.4 ÷ 100 = 0.034
∵ The value of the account reached to $2,930
∴ A = 2930
→ Substitute these values in the formula above to find t
∵ 2930 = 2400
→ Divide both sides by 2400
∴ =
→ Insert ㏑ in both sides
∴ ㏑() = ㏑()
→ Remember ㏑() = n
∴ ㏑() = 0.034t
→ Divide both sides by 0.034 to find t
∴ 5.868637814 = t
→ Round it to the nearest tenth of a year
∴ t = 5.9 years
∴ It would take 5.9 years to the nearest tenth of a year
