Answer:
13.7ft^2
Step-by-step explanation:
Area for triangle:
The formula for the area of a triangle in this scenario is area=(b*h)/2
The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:
area=(3.6*4.8)/2
area=8.64ft^2 for the triangle
Area for semi-circle:
The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.
The question says to use 3.14 for the value of pi.
The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius
Now, we can just substitute these values into the equation above. So:
area=3.14*(1.8)^2
area=3.14*3.24
area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).
However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:
10.1736/2=5.0868ft^2 for the semicircle.
Total area of shape
Now we have the area of the two separate shapes, we can simply add them together. So:
8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)
Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.
Hope this helped!!

Step-by-step explanation:
A pentagon's angle all add up to 540
[tex]460+x=540[/tex]
[tex]x=80[/tex]
Answer:A 80
Step-by-step explanation:
So a square is all 90° angles so take 90 from 140 and get 50 and 50+50=100 and a triangles thing adds up to 180 so 180-100=80 (I’m not good at explaining sorry)

Which relation is a function?
{(0, –9), (–9, –2), (0, –3)}
{(0, –9), (–9, 0), (–3, –3)}
{0, –9, –2, –3}
{(0, –9), (–2, –3), (–2, 0), (–3, –2)}
Answer:
B
Step-by-step explanation:
Soemthing is a function if it can pass the vertical line test
the vertical line test is when you draw a vertical line and it only touches the graph once
Another way of thinking about this is no function can have two of the same values on the x axis

Solve the simultaneous equations by substitution
2x+7y=5
x+y=5
Answer:
x = 6
y = -1
Step-by-step explanation:
i solved the second equation for 'y' to get 'y = 5 - x'
now i substituted that expression into the first equation for 'y'
2x + 7(5 - x) = 5
2x + 35 - 7x = 5
-5x = -30
x = 6
find 'y':
6 + y = 5
y = 5 - 6
y = -1
y=-1 and x=6
followed by the substitution method

Patty rolls a six-sided number die 120 times. How many times should she expect to roll a
prime number?
Answer is 60 times.
Explanation:
Prime numbers in a die are 2, 3 and 5 (i.e. 3 numbers)
Total outcomes can be 1, 2, 3, 4, 5 and 6 (i.e. 6 numbers)
Probability
= Number of preferred outcomes/ Total number of outcomes
= 3/6
= 1/2
= 0.5
Probability of getting a prime number while throwing the dice 120 times
= 0.5 × 120
= 60 times

In ΔDEF, d = 6.4 inches, e = 7.8 inches and ∠F=33°. Find the length of f, to the nearest 10th of an inch.
9514 1404 393
Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

What is the value of j?
Answer:
68°
Step-by-step explanation:
since the angle given is a complementary angle, we know that the sum of it must equal 180°
let the unknown angle below j be x so,
[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]
now since the angle on the left of j is equal to x we can say
[tex]x+j=180\\j=180-x\\j=180-112\\j=68[/tex]

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]
