Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2

A car is traveling on a highway at a constant speed, described by the equation d = 70t, where d represents the distance, in mile

almond37 [142]

Answer:

84miles

Step-by-step explanation:

Step one:

given data

we are told that the equation that describes the car's speed is

d = 70t-----------1

From the equation, we can see that the speed with which the car is traveling is 70miles per hour, while we are expected to find the distance d when the time is 1.2 hours.

Required

The distance d at 1.2 hours

Step two:

substituting in the expression we have

d= 70*1.2

d=84miles

Graph each inequality y-3x<-4

stealth61 [152]

graph each inequality y-3x<-4

First we solve the inequality for y

Add 3x on both sides, so inequality becomes

y < 3x -4

Now we graph it

for graphing , replace < symbol with = sign

y= 3x - 4

Now make a table, assume some number for x and find out y

x y

-1 y=3(-1)-4 = -7

0 y=3(0)-4 = -4

1 y=3(1)-4 = -1

Now plot (-1,-7), (0,-4) ,(1,-1) on graph

Join all the points and make a dotted line ( dotted line for < or > symbol)

now we do shading

for < symbol we shade down

for > symbol we shade up

The graph is attached below

Divide. Write each quotient in simplest form. 2/3 ÷ 2 = _____ Show step-by-step solution.

never [62]

The answer is $\frac{1}{3}$

$\frac{2}{3}$ ÷ 2 = $\frac{2}{3}$ ÷ $\frac{2}{1}$

If $\frac{a}{b}$ ÷ $\frac{c}{d}$ = $\frac{a*d}{b*c}$ , then:
$\frac{2}{3}$ ÷ $\frac{2}{1}$ = $\frac{2*1}{3*2}$

Now, 2 can be canceled out from $\frac{2*1}{3*2}$ :
$\frac{2*1}{3*2}= \frac{1}{3}$
