Answer:
28.6 m²
Step-by-step explanation:
The measurements of the square are 4 by 4; this gives us an area of
4(4) = 16 m²
The quarter circle has a radius of 4 m. The area of a circle is given by
A = πr².
Since we have a quarter circle, we multiply this by 1/4:
A = 1/4πr²
Using 3.14 for π and 4 for r,
A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²
Together this gives us a total area of 16+12.56 = 28.56 m².
This rounds to 28.6 m².
Let
A=8t-3
B=6t+5
we know that
<span>total earnings=A+B
</span>so
total earnings=(8t-3)+(6t+5)------> (8t+6t)+(-3+5)------> (14t+2) <span>dollars
the answer is
</span>(14t+2) dollars<span>

Answer:
41.666 cm³ or 41.7 cm³ rounded to the nearest tenth.
Step-by-step explanation:
Volume of a square pyramid = base length² × height ÷ 3
25 × 5/3 = 41. 666
Have a great day:)
I believe this question logically tells us to find the value of w. The two equations are already equated. Since there is 1 unknown and 1 equation, the system is solvable. The solution is as follows:
5/(6w+21) = -1/3(2w - 9)
5/(6w+21) = -1/(6w - 27)
Cross multiplying the terms:
5(6w - 27) = -1(6w +21)
30w - 135 = -6w - 21
30w + 6w = -21 + 135 = 114
36w = 114
w = 114/36
w = 19/6 or 3.167
