Answer: 13

Step-by-step explanation: Before taking the absolute value of a number, always simplify what's inside the absolute value as much as possible.

So here we have -5 - 8 inside the absolute value which can be thought of as -5 + -8 or -13. So we have |-13| which is +13.

Remember, absolute value means distance from zero on a number line so the absolute value of any number will be the positive version of that number.

Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

Gekata [30.6K]

Answer:

1/6

Step-by-step explanation:

There are 6 numbers on a dice

1,2,3,4,5,6

the even numbers are 2,4,6

so there are 3/6 chance of getting an even number

3/6=1/2

5 and 6 are the two numbers greater than 4

so there are 2/6 chance of getting a number greater than 4

2/6=1/3

So for both to happen chance = 1/2 × 1/3

= 1/6
