The cars will be 330 miles apart after three hours (1.00 pm) from 10.00 am (starting time).

<u>Step-by-step explanation:</u>

Data given for first car,

Rate (speed of car 1) = 60 miles/hour

Distance can be calculated by considering ‘X’ for time as,

               \text {rate}=\frac{\text {distance}}{\text {time}}

               distance of first car = rate \times time =60 \times X miles

Similarly, data given for first car

Rate (speed of car 2) = 50 miles/hour

               distance of second car = rate \times time =50 \times X miles

Need to calculate at what time both the cars are 330 miles apart, so the equation would be,

Distance of first car + distance of second car = 330 miles

              60 X + 50 X = 330  

               110 X = 330

               X=\frac{330}{110}=3 \text { hours }

Already given that both the cars leave at 10.00 am, so the time would be 10 am + 3 hours = 1.00 pm.

Hence, it takes three hours for the cars to get 330 miles apart.

What is the length x of the right triangle, rounded to the nearest<br> tenth?
Zarrin [17]

Answer:

109.5; B

Step-by-step explanation:

From your identity,

CosA = adjacent/ hypothenus

A represent an arbitrary angle between the sides in question.

In the question above, A=64

Hypothenus is the longest side and adjacent is the side just below the angle .

In the above case,

Hypothenus= X

adjacent =48

This means;

Cos64 = 48 /X

X = 48 / cos64; [ from cross multiplication and diving through by cos64]

X = 48 /0.4383 [ cos64 in radian = 0.4383]

= 109.51

= 109.5 to the nearest tenth.

Note( do your calculation of angle in radian or else, you won't get the answer)

Write the equation of a line that is parallel to {y=0.6x+3}y=0.6x+3y, equals, 0, point, 6, x, plus, 3 and that passes through th
Dominik [7]

y = 0.6x - 3.2  
The general form of the desired equation is 
y = mx + b
 where
 m = slope of the line
 b = y intercept of the line 
 If two lines are parallel, their slopes will be the same, Since the slope of the
given line "y = 0.6x +3" is 0.6, that will also be the slope of the desired line.
So our equation becomes:
 y = 0.6x + b 
 Now we can substitute the x and y value of the desired point we want the new line to pass through and find b. So
 y = 0.6x + b
 -5 = 0.6(-3) + b
 -5 = -1.8 + b
 -3.2 = b 
 So the desired equation is now 
y = 0.6x - 3.2

What is the value of x3 × y1 when x = 5 and y = 10​
katovenus [111]

Answer:

150

Step-by-step explanation:

To solve the problem, put 5 instead of x, so 5*3

and put 10 instead of y, so 10*1

when combined,

(5*3) * (10*1)

= 15 * 10

= 150

Hope this helps!!

Let me know if I'm wrong...

1/2 * 14*24*2= 336

The base l*w

10*14= 140

Sides l*w

25*10*2= 500

500+140+336=976
