In the expression shown p represents a rational number. 4p. what value of p makes the expression equal a number less than 4?

Semenov [28]

C: 7/8
Explanation: Since we want a number that makes 4p less than 4, we need to find a number for p that is less than 1. By looking at each fraction, only 7/8 will render it less than 4

What is the area of the figure? 40 ft2 84 ft2 96 ft2 can't be determined

mina [271]

Answer:

$A=80\ ft^2$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle

step 1

Find the area of the triangle

The area of the triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=16\ ft$

To find out the height of the triangle Apply the Pythagorean Theorem

$10^2=(16/2)^2+h^2$

solve for h

$100=64+h^2$

$h^2=100-64$

$h^2=36$

$h=6\ ft$

Find the area of triangle

$A=\frac{1}{2}(16)(6)$

$A=48\ ft^2$

step 2

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=16\ ft\\W=2\ ft$

substitute

$A=(16)(2)=32\ ft^2$

step 3

Find the area of the figure

Adds the areas

$A=48+32=80\ ft^2$

does anyone know how to solve this? i dont remember doing any problems in class related to this and this single question alone h

Serggg [28]

Answer:

The answer to your question is below

Step-by-step explanation:

Process

1.- Get two points of each line to find the equation of each line

Continuous line A (-10, 0) B (0, 9)

Dotted line C (-2, -3) D (0, -10)

Slope continuous line m = $\frac{9 - 0}{0 + 10} = = \frac{9}{10}$

Slope dotted line m = $\frac{-10 + 3}{0 + 2} = \frac{-7}{2}$

2.- Get the equation of each line

Continuous line y + 0 = 9/10 (x + 10)

y = 9/10x + 9

Dotted line y + 3 = -7/2(x + 2)

y + 3 = -7/2x - 7

y = -7/2x -7 - 3

y = -7/2x - 10

3.- Find the inequalities

Continuous line (we need the upper area of the line, we use ≥)

y ≥ 9/10x + 9

The Dotted line (we also need the upper area, we use >)

y > -7/2x - 10
