Find the area of this figure.

Answers

Answer:

144 ft^2

Step-by-step explanation:

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

What is the distance between points A(-3,4) and B(1,-2)? Round to the nearest 10th if necessary.

A. 6.08
B. 6.1
C. 6.5
D. 7.2

Answers

Answer:

D. 7.2

Step-by-step explanation:

6^2 +4^2 = c^2

sqrt 36 + sqrt 16 = c^2

c^2 = sqrt 52 = 7.21110255 = 7.2

Answer:

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

=√(7)²+(-3)²

= √49+9

= √58

=7.2

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.

Answers

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.

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

Answers

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

A=320^2!
Length x width = area

Answers

Answer: 380

Step-by-step explanation: Create an equation, so if 65% waved then 35% of the total (x) didn't wave, which are 133 people, so .35x=133, solve for x so x=133/.35 so x=380

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

Answers

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.
