Answer:

45 - 25 = 20 / 10 = 2 meaning he used the boat for 2 hours.

Step-by-step explanation:

Its the same this as before you start by writing it out how the way PEMDAS works. PEMDAS is ( Parenthesis, Exponents, Multiplication, Division, Adding, and Subtraction). Also i accidentally messed up my other answer so give me a sec.

Trapezoid ABCD is graphed in a coordinate plane.

Ann [662]

Answer:

Step-by-step explanation:

he coordinates of the vertices of the trapezoid ABCD are:

A=(-5,-2)=(xa,ya)→xa=-5, ya=-2

B=(-1,2)=(xb,yb)→xb=-1, yb=2

C=(0,-1)=(xc,yc)→xc=0, yc=-1

D=(-2,-3)=(xd,yd)→xd=-2, yd=-3

yi x(i+1) xi yi xi y(i+1)

-5 -2

(-2)(-1)=2 -1 2 (-5)(2)=-10

(2)(0)=0 0 -1 (-1)(-1)=1

(-1)(-2)=2 -2 -3 (0)(-3)=0

(-3)(-5)=15 -5 -2 (-2)(-2)=4

S1=-10+1+0+4→S1=-5

S2=2+0+2+15→S2=19

Area: A=(1/2) Absolute value (S1-S2)

A=(1/2) Absolute value (-5-19)

A=(1/2) Absolute value (-24)

A=(1/2) (24)

A=24/2

A=12

The area of the trapezoid is 12 square units

It is known that 5< x< 8. find all possible values of the expression, 6x, -10x,x-5,3x+2

Nuetrik [128]

Answer:

Part 1) $30< 6x< 48$

Part 2) $-80< -10x< -50$

Part 3) $0$

Part 4) $17< 3x+2< 26$

Step-by-step explanation:

we know that

$5< x< 8$

The solution for x is the interval ----> (5,8)

All real numbers greater than 5 and less than 8

Part 1) Find all possible values of the expression 6x

For x < 8

The expression value is 6x < (6)(8) -----> 6x < 48

For x > 5

The expression value is 6x > (6)(5) -----> 6x > 30

therefore

$30< 6x< 48$

Part 2) Find all possible values of the expression -10x

For x < 8

The expression value is -10x > (-10)(8) -----> -10x > -80

For x > 5

The expression value is -10x < (-10)(5) -----> -10x < -50

therefore

$-80< -10x< -50$

Part 3) Find all possible values of the expression x-5

For x < 8

The expression value is x-5 < 8-5 -----> x-5 < 3

For x > 5

The expression value is x-5 > 5-5 -----> x-5 > 0

therefore

$0$

Part 4) Find all possible values of the expression 3x+2

For x < 8

The expression value is 3x+2 < 3(8)+2 -----> 3x+2 < 26

For x > 5

The expression value is 3x+2 > 3(5)+2 -----> 3x+2 > 17

therefore

$17< 3x+2< 26$
