Find the area of each figure. Round to the nearest tenth if necessary.

natita [175]

Answer:

Solution given:

diameter(d)=6mm

base(b)=8mm

height (h)=5mm

Area of figure=area of parallelogram +area of semi circle

base*height+½π(d/2)²
8*5+½*π×(6/2)²
40+14.14
54.4mm²
Area :54.14mm²

for triangle

base[b]=6ft

height(h)=9ft

for square

length[l]=9ft

Area of figure=area of square +area of triangle

=l²+½*b*h
=9²+½*6*9
=81+27
=108ft²
Area: 108ft²

42 is 96% of what number?

Law Incorporation [45]

Let, the number = x
It would be: x * 96% = 42
x * 0.96 = 42
x = 42 / 0.96
x = 43.75

In short, Your Answer would be 43.75

Hope this helps!

3. Three years ago, Jane was three times as old as Alice. In two years time, the sum of their ages will be 62. Determine their p

anzhelika [568]

3 yrs ago:

Alice - x
Jane - 3x

Fast forward 2 years... 1 year ago:

Sum of their ages = 62

Equation to solve: x + 3x = 62
4x = 62
----- -----
4 4

x = 15.5

From this, we can deterime that Alice is 15 1/2 years old.

Then, plug in 15.5 for x in 3x to find Jane's age.

15.5 × 3 = 46.5

From this, we can determine that Jane is 46 1/2 years old.

I hope this helps you to understand this problem better.

Find the midpoint of the line segment whose endpoints are (2.6, 5.1) and (3, 4.7).

Tresset [83]

$(2.6, 5.1) \Rightarrow x_1=2.6,y_1=5.1
\\(3,4.7)\Rightarrow x_2=3,y_2=4.7
\\
\\x= \frac{x_1+x_2}{2}= \frac{2.6+3}{2}=2.8
\\
\\y= \frac{y_1+y_2}{2}= \frac{5.1+4.7}{2}=4.9
