6. If Birr 2500 invested at 6% simple interest per annum,
for 3 year, what is the interest
250
540
450
2950​

Answers

Answer:

The interest is 450C

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

I is the intersetP is the investment amountr is the rate in decimalt is the time in years

∵ Birr invested 2500 at 6% simple interest per annum for 3 years

P = 2500

∵ r = 6%

→ Divide it by 100 to change it to decimal

∵ 6% = 6 ÷ 100 = 0.06

r = 0.06

t = 3

→ Substitute them in the formula above

∵ I = 2500 × 0.06 × 3

I = 450

The interest is 450

Step-by-step explanation:

Key skills needed: Fraction operations, decimal conversion

1) We are given the hint to use 9 as "b", and we get:

---> [tex]a = \frac{16}{8}(9) + \frac{10}{8}[/tex]  

Let's do  [tex]\frac{16}{8}(9)[/tex]

--> [tex]\frac{16}{8}[/tex] is the same as [tex]16[/tex] ÷ [tex]8[/tex]

16 divide by 8 is 2.

2) This means that it would be  ---> [tex]2(9)[/tex]  which is simply 2 times 9.

2 times 9 = 9 + 9 = 18

3) With that result, it would be  ---> [tex]a = 18 + \frac{10}{8}[/tex]

Now, do [tex]\frac{10}{8}[/tex] (10 divided by 8)  ---> Get 1.25

4) 18 + 1.25 = 19.25, so --> [tex]a = 19.25[/tex] is the answer

Some number was divided into 42. This quotient was then multiplied by 8,after which the resulting product was added to 10. Given this sum totalled to 34,find the initial number.

Answers

Answer:

126

Step-by-step explanation:

In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.

(((x / 42) * 8) + 10) = 34   ... subtract 10 from both sides

((x / 42) * 8) = 24 ... divide both sides by 8

(x / 42) = 3  ... multiply both sides by 42

x = 126

Finally, we can see that the initial value was 126

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular.

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

What is perpendicular with examples?

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other.

Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

By triangle inequality, the sum of the lengths of any two sides are greater than the length of the third side.

We therefore could set up three inequalities.

Solving these, we get x>9, x>-9, x<21 i.e. 9 < x < 21.
