The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width
Answer:320ft^2
Step-by-step explanation:
80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

Matthew had to make a bridge for his math class. It had to be at least 1 1/2 feet long. Harold made a bridge that was 2/13 times as long as Matthew’s. Write and solve an equation that will help you figure out how long Harold’s bridge was. Explain the steps you took to solve the problem.
Answer:
Step-by-step explanation:
2 / 13 = 15.38% or 15.38..... If Matthew's bridge is 1 1/2 feet long which is 45.72cm then 45.72 + 15.38 = 61.1cm > convert into feet > 1.55194 ft.

We can split this shape into a rectangle and into a trapezoid. The rectangle we can use is the one with side lengths of 12.4 and 6, and to find this area we just multiply these two to get 74.4.
The trapezoid we can make has bases of 5 and 12.4, and has a height of 8 ft. The equation representing the height of a trapezoid is [tex]\\\frac{1}{2} (b_{1}+b_{2} )*h[/tex], and plugging in to this equation we get:
1/2(5+12.4)*8
1/2(17.4)*8
8.7*8
69.6
Finally, we add the area of the trapezoid and rectangle together to get 69.6+74.4=144

The variable in the equation 26 = 1 – 3r is r. Remembering the form ax + b = c, what are the values of the constants, a, b, and c in the equation?
The value of the constant a, b and c in the equation are -3, 1 and 26 respectively.
What is variable?Variable are numbers represented by letters in a mathematical equation. Therefore,
26 = 1 - 3rUsing the form ax + b = c, where a, b and c are constant.
The value of a, b and c in the expression 26 = 1 - 3r can be solve as follows:

Step-by-step explanation:
I did the math and thats what i got even rounded up
The value of the expression 3.14 x 4 x 4 x 7 is 351.4 and for expression 3.14 x 7 x 7 x 4 is 615.4.
To round the expression to the nearest tenth, we need to evaluate it first. Let's calculate each expression:
3.14 x 4 x 4 x 7 = 351.36
3.14 x 7 x 7 x 4 = 615.44
Now, let's round each result to the nearest tenth:
Rounding 351.36 to the nearest tenth gives us 351.4
Rounding 615.44 to the nearest tenth gives us 615.4
Based on the given options, neither result matches exactly.
However, option A (124.6) is the closest rounded value to 351.4.

Find the discriminant and the number of real roots for this equation.
4x2 + 12x + 9 = 0
A. -144; one real root
B. -144; no real roots
C. 0; one real root
D. 0; two real roots
Discriminant and the number of real roots for this equation are 0, one real root.
What is discriminant?Discriminant of a polynomial in math is a function of the coefficients of the polynomial.
The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
Given equation
[tex]4x^{2} +12x+9 = 0[/tex]
Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]
= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]
= [tex]\sqrt{144-144}[/tex]
D = 0
Therefore, number of real roots is one.
Hence, discriminant and the number of real roots for this equation are 0, one real root.

c^2 = sqrt 52 = 7.21110255 = 7.2
Answer:
Step-by-step explanation:
Step-by-step explanation:
Distance between two points is given by
|xy|=√(x2-x1)² +(y2-y1)²
So putting the points A(-3,4) B(1,-2) into the equation
|AB|= √(4--3)²+(-2-1)²
