Matt started doing extra chores around the house and his allowance changed from $30 per week to $40 per week. What is the percen

slega [8]

Answer:

33.3%

Step-by-step explanation:

Let's say the percent change is x%. Then the equation is:

30 + x% * 30 = 40

Subtract 30 from both sides:

x% * 30 = 10

Divide by 30:

x% = 10/30 = 1/3

Remember that % simply means "out of 100", so:

x/100 = 1/3

Multiply both sides by 100:

x = (1/3) * 100 = 33.3%

Answer:

$\huge{ \boxed{ \sf{17.68 \: {cm}^{2} }}}$

Step-by-step explanation:

$\underline{ \text{Given}} :$

$\longrightarrow \sf{ \: Length \: of \: a \: rectangle \: = \: 5.2 \: cm}$

$\longrightarrow{ \sf{Breadth \: of \: \: rectangle \: = \: 3.4 \: cm}}$

$\underline{ \text{To \: find} } : \sf{Area \: of \: a \: rectangle}$

$\boxed{ \sf{Area \: of \: a \: rectangle \: = \: Length \: \times \: Breadth}}$

$\mapsto{ \sf{Area \: = \: 5.2 \: cm \: \times \: 3.4 \: cm}}$

$\mapsto{ \sf{Area \: = \: 17.68 \: {cm}^{2} }}$
