RS 40 as a percent of RS 25 with step by step solution​

Mathematics
1 answer:
gregori [183]3 years ago
4 0

Answer:

10

Step-by-step explanation:

Solution for What is 25 percent of 40:

25 percent * 40 =

(25:100)* 40 =

(25* 40):100 =

1000:100 = 10

Now we have: 25 percent of 40 = 10

Question: What is 25 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$40=100\%$.

Step 4: Similarly, $x=25\%$.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$.

$x=25\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{25\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{25}{100}$

$\Rightarrow x=10$

Therefore, $25\%$ of $40$ is $10$

An inscribed angle is an angle formed by two radii that share an endpoint
KATRIN_1 [288]
Check the picture below.

notice, as from the left, we grab those two angles and slap them together on the right, they form a wide angle A, and a smaller inscribed angle B.

now, the blue and red segments that came together, are both making up the inscribed angle B, and also sharing the side or endpoint, in the middle of angle A.

A parabola y=1/2x^2-4x+21 can you help me find the vertex form of this parabola please and thank you :)
ale4655 [162]
Ok 
First factor out the first 2 terms as follows:-

y  = 1/2(x^2 - 8x) + 21

Now complete the square on x^2 - 8x:-

y = 1/2[ (x - 4)^2 - 16] + 21

y = 1/2(x - 4)^2 - 8 + 21

y = 1/2(x - 4)^2 + 13   Answer

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $6750 and her st
pantera1 [17]

Answer:

3.5%

Step-by-step explanation:

1. calculate starting total

6750 + 4210=10960

starting amount = $10,960

2. calculate stock    A2's value

  • decreased by 18%

to make the percentage usable in this equation we need to divide it by 100 to get it in decimal form. ⇒ \frac{18}{100} = 0.18

  • multiply stock A1 by perctage decimal to get the amount decreased

6750(0.18)=1215 ($1,215)

  • subtract stock A1 by decreased amount to get stock A2's value

6750-1215=5535

A2 = $5,535

3. calculate stock    B2's value

  • increased by 20%

to make the percentage usable in this equation we need to divide it by 100 to get it in decimal form. ⇒ \frac{20}{100} = 0.20

  • multiply stock B1 by perctage decimal to get the amount increased

4210(0.20)=842 ($842)

  • add stock B1 with increased amount to get stock B2's value

4210+842=5052

B2 = $5,052

4. get new amount of account

5052+5535=10587

new amount = $10,587

5. find percentage decrease of starting amount to new amount

  • divide starting amount by the new amount

\frac{10960}{10587} = 1.03523188816

  • then subtract by 1

1.03523188816-1 =0.03523188816

  • multiply by 100 to convert to percentage form

0.03523188816(100) =3.523188816

  • and round to <u>nearest tenth</u>

answer is ≈ 3.5%

Clay ordered two suitcases ($44.50 each) from a catalog. He had to
ratelena [41]

Answer:

I believe your answer is C 94.79

If this answer is wrong please let me know my apologies

Step-by-step explanation:

If my math is correct

44.50+44.50=89

89

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 85 × 0.065

tax = 5.53 (tax value rounded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 85 + 5.53 = 90.53

90.53 plus the shipping 3.89=94.79
