Answer:

3x³y √(5xy)

Step-by-step explanation:

√(3x⁴y) √(15x³y²)

Multiply the radicands.  When multiplying, add the exponents (xᵃ xᵇ = xᵃ⁺ᵇ).

√(45x⁴⁺³y¹⁺²)

√(45x⁷y³)

To simplify further, we need to factor out perfect squares (anything with an even exponent).

√(3²·5 x⁶x y²y)

√(3²x⁶y²) √(5xy)

Take the square root of the perfect square (halve the exponent).

3x³y √(5xy)

A student estimated a mass of 250grams, according to the scale the mass is actually 240grams. What is the percent error? (round
NeX [460]

Answer:

4.2%

Step-by-step explanation:

percent error = (estimated value - actual value)/(actual value) × 100%

Here, the estimated value is 250 g, and the actual value is 250 g.

percent error = (estimated value - actual value)/(actual value) × 100%

percent error = (250 g - 240 g)/(240 g) × 100%

percent error = 10/240 × 100%

percent error = 0.041666... × 100%

percent error = 4.2%

Subtract 6 from me. Then multiply by 2. If you subtract 40 and then divide by 4, you get 8. What number am I?
aliina [53]

Answer:

42

Step-by-step explanation:

Let the number be "x"

We translate the word equation to algebraic equation.

First,

subtract 6 from me, so we have:

x - 6

Now,

Multiply by 2, so we have:

2(x-6)

Now,

Subtract 40, then divide by 4:

\frac{2(x-6)-40}{4}

Now, you get "8", so equate this to 8, we get:

\frac{2(x-6)-40}{4}=8

We now solve using algebra:

\frac{2(x-6)-40}{4}=8\\2(x-6)-40=4*8\\2(x-6)-40=32\\2x-12-40=32\\2x-52=32\\2x=32+52\\2x=84\\x=42

The number is 42
