A. 3.91 m²
area of a triangle is (base x height)/2
b=3.4
h=2.3
(2.3)(3.4)=7.82
7.82/2=3.91
**the height of this triangle would be one of the sides because it is a right triangle (sides meet and form perpendicular lines, or a 90° angle)

The incomplete table above summarizes the number of left-handed students and right-handed students by gender for the eighth grad

creativ13 [48]

Answer:

The answer is A

Step-by-step explanation:

x+y=18

5x+9y=122

When you solve this system of equations, you get x=10 and y=8. Thus, 5*10, or 50, of the 122 right-handed students are female. Therefore, the probability that a right-handed student selected at random is female is

50/122

which to the nearest thousandth is 0.410.

Find the distance between A (6,-5) and B(-2,-20)

melomori [17]

Answer:

17i

Step-by-step explanation:

d= (under radical sign) (x2-x1)^2 + (y2-y1)^2

plug in the numbers and simplify and youll get (again under the radical sign) (-8)^2 + (-15)^2

do the math again and youll get -289 under the radical. square root of 289 is 17 and you add the i next to it because it is negative and those numbers aren't real

Which equation represents the graphed function?

makvit [3.9K]

The equation y = –2 x + 3 represents the graphed function.

Answer: Option A

<u>Step-by-step explanation:</u>

As per the mapping points in the attached figure, A (0, 3) and B (1, 1)

Step 1: Find the slope of the line.

We know that the formula to calculate the slope between two points is equal to

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\left(x_{1}, y_{1}\right)=(0,3) \text { and }\left(x_{2}, y_{2}\right)=(1,1)$ . So, the slope ‘m’ would be

$m=\frac{1-3}{1-0}=-2$

Step 2: Find the y-intercept

We know that the y-intercept is the value of y when the value of x is equal to zero. In this problem the y-intercept is the point A (0, 3)

Step 3: Find the equation of the line into slope-intercept form

We know that the equation of the line into slope-intercept form is equal to

y = m x + b

We have m = - 2 and b = 3 as b is equal to the y-coordinate of the y-intercept. Substitute these, we get

y = - 2 x + 3

1 1/4 + 1 1/2 btw im giving easy problems to get points up

sattari [20]

Answer:

2.75 or 2 3/4

Step-by-step explanation:

1 + 1 = 2

1/4 + 1/2 = 3/4

1/4 = 1/4

make 1/2 into 2/4

add 1/4 to 2/4

3/4

2 + 3/4 = 2 3/4 or 2.75
