Step-by-step explanation:

a = 5

b= 9

a + 4b = ?

5 + 4×9 =

5 + 36 = 41

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Find the compound interest on ₹ 31,250 at 12% pa for 2 1/2 years
IRISSAK [1]

Answer:

42,183

Step-by-step explanation:

We will use the Continuous Compounding Interest since a regular interval was not stated.

P(t) = Pe^(rt)

We will plug in the variables to the formula

P(t) = 31250 * e^(.12 * 2.5)

We can simplify and evaluate the compound interest.

P(t) = 42183.08

Given ABCD is a parallelagram diagonals AC and BD intersect at E Prove AE is congruent to CE and BE is congruent to DE
Zepler [3.9K]

In the parallelogram ABCD, diagonals AC and BD intersect at point E.

According to the definition of parallelogram, opposite sides are equal and parallel to each other. That means, AB = DC

Now as AB and DC are parallel, so according to the property of Alternate Interior Angles, we will get:

∠EAB = ∠ECD and ∠EBA = ∠EDC

Thus , in two triangles ΔABE and ΔDCE, two angles and one side are equal. So, ΔABE and ΔDCE are congruent to each other.

That means, AE = CE and BE = DE

So, AE is congruent to CE and BE is congruent to DE

yarga [219]
The area would 30 in^2
Reason:
Area of a triangle =1/2 bh
Area= 1/2 (12)(5)
Area =(6)(5) (because a half times 12 =6)
Therefore Area =30 in^2
Hopefully that helps, if not I apologize

Consider 8x-4 = 810 Because the are equal , the must also be equal. The solution to the equation is x = .
Nostrana [21]

Answer: x = 101.75

Step-by-step explanation:

Hi, to answer this question we have to solve the equation give, by isolating x:

8x-4 = 810

The first step is to Add 4 on both sides:

8x-4+4 = 810+4

8x = 814

Then we have to divide both sides by 8:

8x/8 = 814/8

Finally, the solution is:

x = 101.75

Feel free to ask for more if needed or if you did not understand something.
