Answer:
74-25 is 49
Step-by-step explanation:
The expression we have is:
And we are given some values for x and y:
The first step will be to substitute the given values into the expression:
The next step is to solve 4^2 which is equal to 16:
And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:
Solving this final multiplication we get the result:
Answer: 512

Step-by-step explanation:
Monday: $15
Tuesday: $10
15+10=35
$35 total
Step-by-step explanation:
Firstly, notice that this shape is composed of ³/₄ of a circle and ¹/₂ of a square;
The lower left part is the ¹/₂ square, with only 2 sides (a left and lower side) of length 3 units;
The perimeter of this part of the shape is simply the sum of the two sides:
3 + 3 = 6
The remaining part is the ³/₄ circle, which has a radius of 3 units;
The circumference of a circle is found by the formula:
πd
d = diameter = 2 × radius
We only have ³/₄ of the circle, however, so we only have ³/₄ the circumference:
³/₄ × π(2(3)) = ³/₄ × 6π
= ⁹/₂π (or, equally, 4.5π)
So the total perimeter is the sum of the perimeter of the ¹/₂ square and the ³/₄ circle:
4.5π + 6
