A car is traveling at a speed of 25 meters per second what is the cars speed in kilometers per hour how many kilometers will the

Likurg_2 [28]

Answer:

90 km/h
180 km

Step-by-step explanation:

There are 1000 m in 1 km, and 3600 s in 1 h, so the speed conversion is ...

$\dfrac{25\,m}{s}\cdot\dfrac{1\,km}{1000\,m}\cdot\dfrac{3600\,s}{1\,h}=\dfrac{90\,km}{h}$

The car's speed is 90 km/h.

In 2 hours, the car will travel ...

distance = speed · time = (90 km/h)(2 h) = 180 km

If two points on line l above have coordinates (0, A) and (2, −3), and the slope of the line is A, then what is the value of A?

Vlada [557]

Answer:

A = -1

So, option (B) is the correct answer.

Step-by-step explanation:

The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)

Slope of line = A

Slope of line = $\frac{y_{2} - y_{1}}{x_{2} -x_{1}}$

Now since the slope of line is A and its has two coordinates (0, A) and (2 , -3), ∴

$A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}$

$A = \frac{-3 - A}{2 - 0}$

$2A = -3 - A$

$2A + A = -3$

$3A = -3$

$A = -1$

So, option (B) is the correct answer.

Did I find the area of the composite figures correctly in the pic? If not, help pls?

Annette [7]

No, in problem 1
you said that area of triangle=bh when it should be 1/2bh
the area should be 9 not 18 so triange=9
aera of rectangle is correct
so
27+9=36 in^2 is answer

2. it is 1 rectangle 1 triangle 1 square you forgot the square
rectangle=12 times 4=48
square=4 times 4=16
triangle=1/2bh=1/2(8)4=16
add

48+16+16=80 in^2

remember that
triangle=1/2(base times height)
draw immaginary lines and split shapes, it could help to seperate shapes or/and mmove them around and regroup them
