Answer:
b(4) = -14
Step-by-step explanation:
b(n)=4-6(n-1)
let n=4
b(4) = 4 - 6(4-1)
b(4) = 4-6*3
b(4) = 4-18
b(4) = -14
perimeter of the triangle is P= 3s, where s is
the side length. Solve for s. Use your formula to
find the dimensions of the flag in feet and the
area in square feet when the perimeter of the
triangle is 126 inches.
Answer:
Step-by-step explanation:
The missing figure of the exercise is attached.
We know that the perimeter of the triangle is given by:
Where "s" is the side lenght of the triangle.
Solving for "s", we get:
Therefore, if the perimeter of the triangle is 126 inches, its side length is:
Since , we know that "s" in feet is:
The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width
We can observe in the figure that the lenght and the width of the flag are:
Then, the dimensions of the flag are:
And the area is:
When x=0 then y=3. Only B goes through (0,3).
Answer: B
Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
Given : 58% of 121.
To find : estimate 58% of 121 by using 10%.
Solution : We have given 58%
Estimate of 58% is 60%
We need to use 10%
We can write 60% as 6 times of 10%
Since , 10% of 121
= 12.1
60% = 6 times of 10%
Plugging the values
60% == 6 times of 12.1
6 *12.1 = 72 .6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Therefore, 58% of 121 by using 10% is 70.18.
Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3
Step-by-step explanation:
The data we have is:
Gonzales has $42.50
He wants to buy:
a shirt that costs $29
some bracelets that cost $4.50 each.
The equation that we need to solve is:
Total cost = money that Gonzales has.
The cost is $29 + x*$4.50
where x is the number of bracelets he can buy.
The equation that we need to solve is:
$29 + x*$4.50 = $42.50
to solve it we must isolate x:
x*$4.50 = $42.50 - $29 = $13.50
x = 13.50/4.50 = 3
So we have that Mr. Gonzales can buy a total of 3 bracelets.
