The test has 50 questions on it,<br> you miss 25 questions,<br> what percent did you get?

Helen [10]

If a test had 50 questions on it, and you missed 25 of them, that would mean that you got a 25/50, which, when divided, equals 1/2 or 0.5, which converts into 50%.

The vertices of a rectangle are located at (1, 2) (5, 0) (2, -6) and (-2, -4) what is the area of the rectangle

galina1969 [7]

Answer:

Option 2) 30 square units

Step-by-step explanation:

step 1

Plot the rectangle to better understand the problem

we have

A(1, 2),B(5, 0),C(2, -6) and D(-2, -4)

see that attached figure

step 2

Find the length of the sides

Remember that'

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

<em>Find the length side AB</em>

we have

A(1, 2),B(5, 0)

substitute in the formula

$d=\sqrt{(0-2)^{2}+(5-1)^{2}}$

$d=\sqrt{(-2)^{2}+(4)^{2}}$

$d_A_B=\sqrt{20}\ units$

<em>Find the length side BC</em>

we have

B(5, 0),C(2, -6)

substitute in the formula

$d=\sqrt{(-6-0)^{2}+(2-5)^{2}}$

$d=\sqrt{(-6)^{2}+(-3)^{2}}$

$d_B_C=\sqrt{45}\ units$

step 3

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=BC=\sqrt{45}\ units$

$W=AB=\sqrt{20}\ units$

substitute

$A=(\sqrt{45})(\sqrt{20})=\sqrt{900}=30\ units^2$

2. Evaluate the expression -4r +5 y-14<br> when r = 0 and y=-<br> 55

Alecsey [184]

Answer:

Answer is 261

Step-by-step explanation:

-4r+5y-14 r=0 y=55

insert "r" and "y" values into equation

=-4(0)+5(55)-14

evaluate;

-4(0)=0

5(55)=275

so, now the equation would look like this;

=275-14
