The correct answer is 23/6. Hope this helps.
Answer:
52 cm^2
Step-by-step explanation:
Solve by splitting the figures into 2 parts and finding their areas separately:
Rectangle:
8 × 5 = 40
Triangle:
1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12
Total: 40 + 12 = 52
Answer:
Base
Step-by-step explanation:
An exponent is a number/letter written to the top-right of a mathematical expression called the base. It means that the base will raised to a certain power.
The radical sign is a symbol for the square root of a number.
Answer:
Ques 1) 1440°
Ques 2) 4000
Ques 3) 33
Step-by-step explanation:
Ques 1)
The sum of the measures of the angles in degrees of a polygon with 'n' sides is given by: 180×(n - 2).
Now we have to find the sum of the measures the angles of a polygon with 10 sides.
i.e. n=10
Hence the value of the expression 180×(n-2) when n=10 is given by:
180×(10-2)=180×8=1440.
Hence, the sum of measure of the angles of a polygon with 10 sides is: 1440°.
Ques 2)
The Expression 500v gives the number of points a player earns for completing v voyages in video game.
We are asked to find the number of points earned for completing 8 voyages.
i.e. v=8 the value of 500v will be 500×8=4000.
Hence, 4000 points are earned for completing 8 voyages.
Ques 3)
we have to find the value of the question as given in the figure:
7x+y+16 for x=2 and y=3.
Hence, we find the value of the expression:
7×2+3+16=33.
Hence, the value of the expression is 33.
