Answer:
the rate percent per annum at which birr 142 will earn birr 59.65 in 12 years is → 3.5%
ML stands for milliliters. The prefix milli means 1,000. One liter contains 1,000 milliliters.
Therefore you want to convert the 200 mL to liters by dividing by 1,000. This gives you 200mL = 0.2L.
If you subtract the 0.2L from 1.2L you get 1L left.
Answer:
-2 < x < 7
Step-by-step explanation:
Compound inequality is the one having two inequalities joined together.
Given that:
In compound equality these conditions will be written as:
-2 < x < 7
It depicts that value of x is greater than -2 and smaller than 7
Answer:
15 years
Step-by-step explanation:
Let e represent Edith's age. Then e also represents her brother's age.
Then:
e = 5e - 60.
Consolidating the e terms, we get 60 = 4e. Thus, e = 15.
Edith is 15 years old. So is her brother.
Answer:
scale factor = 20%
Step-by-step explanation:
A scale factor is a multiplier which can be used to determine the rate between two or more dimensions.
In the given figure, the sides of the original triangle is 5 times greater than that of the copy. Thus,
the scale factor = x 100%
= x 100%
= 20%
The scale factor of the original triangle to its copy is 20%. This implies that the dimensions of the original triangle are multiplied by 20% to determine that of the corresponding copy triangle. Thus, we scale down the dimensions of the original triangle by 20%.
