There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are r

Andrej [43]

Answer:

Red: 161 White: 77

Step-by-step explanation:

Given there are 238 marbles in a jar, and there are 42 more red marbles than white marbles, we need to divide the number of marbles by two, as there are, presumably, two colors.

238 / 2 = 119

After doing this, we subtract 42 from one of the two 119s, and we add 42 to the other.

119 - 42 = 77

119 + 42 = 161

The value with 42 added is the red marble count, and the value with 42 subtracted is the white marble count.

Answer:

% Decrease = 19.2 ; 19.2%

Step-by-step explanation:

% Decrease = (Original Price - New price)/ Original price × 100

Find the percent of change round to the nearest percent original: 50 new: 70

kykrilka [37]

The percent change is 40%

Step-by-step explanation:

The percent change is given by the formula

$Percent\ change=\frac{New\ value-Original\ value}{Original} * 100$

Here

New value = 70

Original value = 50

Putting the values in the formula

$Percent\ change=\frac{70-50}{50}*100\\=\frac{20}{50}*100\\=0.4*100\\=40\%$

The percent change is 40%

Which applies the power of a product rule to simplify (5 t) cubed?

Elena L [17]

Answer:

(5 t ) cubed = 5 cubed . t cubed = 125 t cubed applies the power of a product rule to simplify (5 t) cubed ⇒ 3rd answer

Step-by-step explanation:

Let us revise some rules of exponents

$a^{m}$ × $a^{n}$ = $a^{m+n}$

$a^{m}$ ×÷ $a^{n}$ = $a^{m-n}$

$(a^{m})^{n}$ = $a^{m.n}$

$(a.b)^{m}$ = $a^{m}$ . $b^{m}$

To simplify $(5t)^{3}$

∵ 5t means 5 × t

∵ Both of them are cubed

- Use the 4th rule above

∴ $(5t)^{3}$ = $(5)^{3}.(t)^{3}$

∵ (5)³ = 5 × 5 × 5 = 125

∴ $(5t)^{3}$ = $(5)^{3}.(t)^{3}$ = 125 t³

(5 t ) cubed = 5 cubed . t cubed = 125 t cubed applies the power of a product rule to simplify (5 t) cubed
