Answer:

745.44 square mm

Step-by-step explanation:

The figure can be decomposed into ...

a semicircle of radius 12.5 mm
a rectangle 12.5 mm by 25 mm
a triangle 12.5 mm by 30 mm

The relevant area formulas are ...

Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²

Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²

Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²

Total area of the figure is ...

245.437 +312.500 +187.500 = 745.437 . . . mm²

The area of the figure is about 745.44 square mm.

Answer:

19 wrong answers.

Step-by-step explanation:

Given:

Sahil got 28 questions right.

Angelina got 7 more wrong answers than Sahil.

There where 40 questions on the test.

Question asked:

How many answers did Angelina get wrong on the math test ?

Solution:

Total questions on the test = 40

Number of right answers, Sahil got = 28

Number of wrong answers, Sahil got = 40 - 28 = 12

As Angelina got 7 more wrong answers than Sahil,

Number of wrong answers, Sahil got = 12

Then, number of wrong answers, Angelina got = 12 + 7 = 19

Therefore, 19 answers did Angelina get wrong on the math test out of 40.

Answer:

Bob forgot to distribute 3 to 1.50 in the parentheses

Step-by-step explanation:

Bob made the mistake in his first step.

In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.

But, Bob only distributed it to x, which led him to get the wrong answer.

So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50
