Answer:
Step-by-step explanation:
We need to study the structure well
We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is C.
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
s = 1.8
Step-by-step explanation:
Step 1. Subtract .6 from both sides
s/3 = .6
Step 2. Multiply it all by 3 to isolate variable.
s = 1.8
Answer:
12 feet x 4 feet
Step-by-step explanation:
The classroom wall is 160 feet, and no more than 30% of it may be covered.
Multiply 160 times .3 to get the maximum amount of square feet that the bulletin board can cover.
You get 48 square feet for the bulletin board.
The length of the board is three times as long as the width, so the length must be 12 and the width must be 4 feet.
Answer: 12 feet x 4 feet
Answer:
d + n = 22 and 0.1d + 0.05n = 1.9
Step-by-step explanation:
Let d represents the number of dimes and n represents the number of nickel.
Total of dimes and nickels = 22
Therefore, d + n = 22
1 dime = 10 cents = 0.1
1 nickel = 5 cents = 0.05
Value of 22 dimes and nickel = $1.90
So, 0.1d + 0.05n = 1.9
Hence, d + n = 22 and 0.1d + 0.05n = 1.9 models the given situation.
