Answer:

5x + 8y = 24

Step-by-step explanation:

Given :

$y=-\frac{5x}{8} +3$

……………………

$y=-\frac{5x}{8} +3$

$\Longleftrightarrow 8\times y=8\times (-\frac{5x}{8} +3)$

$\Longleftrightarrow 8y=-5x+24$

$\Longleftrightarrow 5x+8y=24$

Answer:

0.37

Step-by-step explanation:

we have given that emails arrives at the server at the rate of 10 per hour means $\frac{10}{60}=0.166$ per minute

we have to find the probability that the time difference between the two email is more than 2 minute

so probability $P\left ( X> 2 \right )=e^{-2\lambda }=e^{-2\times 0.166}=0.7166$

A freight train departs from one train station to its destination at a constant speed. Suppose the distance the train is from th

barxatty [35]

Answer:

108 miles

Step-by-step explanation:

Given the points (0.5, 135) and (2,81)

Diatnce between two points :

D = √(x2 - x1)² + (y2 - y1)²

X1 = 0.5 ; y1 = 135 ; x2 = 2 ; y2 = 81

D = √(2^2 - 0.5^2) + (81^2 - 135^2)

D = √(4 - 0.25) + (6561 - 18225)

D = √3.75 −11664

D = 107.98263

D = 108 miles

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

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