Find the area of all three of them then add them together.
TRIANGLE:
A=1/2*b*h
A=1/2*8*h
The height is not given to us, so we need to make a separate triangle to figure it out. (Work is in picture 1)
A=1/2*8*6.9
A=27.7
SQUARE:
A=s^2
A=8^2
A=64
POLYGON:
Area=1/2*a*p
The polygon has 5 sides.
The perimeter will be 8*5, or 40.
The apothem is found in the next snapshot.
A=1/2*1.9*40
A=38
TOTAL AREA:
38+22.7+64=124.7

Michelle tried to solve an equation step by step. \begin{aligned} t-\dfrac35&=\dfrac45\\\\ t-\dfrac35+\dfrac35&=\dfrac45
valentinak56 [21]

Answer:

Step 2

Step-by-step explanation:

Michelle's step in trying to solve the equation is given below:

\begin{aligned} t-\dfrac35&=\dfrac45\\\\ t-\dfrac35+\dfrac35&=\dfrac45+\dfrac35&\green{\text{Step } 1}\\\\ t&=1&\blue{\text{Step } 2} \end{aligned}

Michelle made a mistake in Step 2.

The right hand side of Step 1:  \dfrac45+\dfrac35\neq 1

Rather, the correct sum is:

\dfrac45+\dfrac35=\dfrac75\\\\=1\dfrac25

Anna11 [10]

Answer: 25%

Step-by-step explanation:

Given : Previous baby's weight = 18 pounds

New baby's weight =  24 pounds.

Increase in weight = New weight -Previews weight

=24 pounds - 18 pounds  =6 pounds

Percentage increase in baby's weight ==\dfrac{\text{Increase in baby's weight}}{\text{previous weight}}\times100

\\\\=\dfrac{6}{24}\times100=25\%

Hence, the percentage increase in baby's weight = 25%
