What is the final amount if 2250 is decreased by 2% followed by a further 3% decrease?

Marrrta [24]

Answer:

2138.85

Step-by-step explanation:

2250 decreased by 2% is

2% of 2250 subtracted from 2250

That’s

2% /100% x 2250

0.02 x 2250

So, decrease = 2250 - 45

= 2205

Now 2205 decreased by 3%

3% of 2205

3% /100% x 2205

0.03 x 2205

66.15

Decrease = 2205 - 66.15

= 2138.85

Algebra: Find x ....

luda_lava [24]

Answer:

Step-by-step explanation:

The triangles are similar, thus the ratios of corresponding sides are equal, that is

$\frac{2x+1}{x+4}$ = $\frac{40}{25}$ = $\frac{8}{5}$ ( cross- multiply )

5(2x + 1) = 8(x + 4) ← distribute parenthesis on both sides )

10x + 5 = 8x + 32 ( subtract 8x from both sides )

2x + 5 = 32 ( subtract 5 from both sides )

2x = 27 ( divide both sides by 2 )

x = 13.5 → d

Solve for b. 7 b 12 b= ✓ [?] Pythagorean Theorem: a2 + b2 = c2 Enter

fomenos

Answer: $b=\sqrt{95}$

Step-by-step explanation:

To solve for b, we want to use the Pythagorean Theorem as given.

b and 7 are the legs, and 12 is the hypotenuse.

$7^2+b^2=12^2$ [exponent]

$49+b^2=144$ [subtract both sides by 49]

$b^2=95$ [square root both sides]

$b=\sqrt{95}$

Now we know $b=\sqrt{95}$ .
