6. If Birr 2500 invested at 6% simple interest per annum,

Mathematics

1 answer:

Olegator [25]3 years ago

Answer:

The interest is 450 ⇒ C

Step-by-step explanation:

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

I is the interset

P is the investment amount

r is the rate in decimal

t 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

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne

Mrrafil [7]

<h3>Answer: Choice C. (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth grader

Anon25 [30]

Answer:

The number of students in the school band = 70

40% of students in the school band are sixth graders.

20% of students in the school band are seventh graders.

We have to find the number of band members that are sixth graders.

The number of sixth graders in school band are:

$40\% of 70$

$0.40 \times 70$

$28$

Therefore, there are 28 band members that are sixth graders.
