What is 25% Of 30% Of 400?

Mathematics
1 answer:
marta [7]2 years ago
3 0

Answer:

25% of 30% of 400 = 30

33% decrease in value

Step-by-step explanation:

You can either get 30% of 400 first then 25% of 400 or you can get the total percentage of 400.

Method 1:

30% of 400 = 0.3 of 400 = 0.3 * 400 = 120

25% of 120 = .25 of 120 = .25 * 120 = 30

Method 2:

30% of 25% = 0.3 * 0.25 = 0.075 = 7.5% of 400

7.5% of 400 = 0.075 of 400 = 0.075 * 400 = 30

5.) To find the percentage  of the new price, you can build the equation below.

\frac{new price}{original price} = \frac{percent}{100}

\frac{200,000}{300,000}  = \frac{x}{100}

20,000,000 = 300,000x

x = 66.667

The percentage decrease in price is then 100% of the original price - 66.667% of the original price = 100% - 66.67% = 33.33% = 33% decrease.

Write in point-slope form an equation of the line that passes through the point (3,0) with slope 23.
Radda [10]

Answer:

y-0=23(x-3)

Step-by-step explanation:

Point-slope form: y-y_1=m(x-x_1) when the given point is (x_1,y_1) and m is the slope

y-y_1=m(x-x_1)

Plug in the point

y-0=m(x-3)

Plug in the slope

y-0=23(x-3)

I hope this helps!

Find the solution to this system: 5x-2y=-11 -2x+5y=17 Multiplying equation 2 by will create additive inverses for the x-coeffici
Pachacha [2.7K]

Step-by-step explanation:

5x-2y=11

-2x+5y=17

eqn1×2=10x-4y=22

eqn2×5= -10x+25y=85

21y=107

y=107÷21

5x-2(107/21)=11

5x-(214/21)=11

105x-214=231

105x= 445

x=445/105=
