sashaice [31]3 years ago
4 0

Answer:

3.79 miles per hour to the nearest hundredth.

Step-by-step explanation:

There are 3600 seconds in 1 hour.

50  feet in 9 seconds = 50/9 feet per second.

= (50/9) * 3600  feet  per hour

= (50/9) * 3600 / 5280 miles per hour.

= 50 * 400 / 5280

= 3.79 miles / hour.

PLS PLS PLS HELP IM BEHIND The first sequence rule is multiply by 3 starting from 4. The second sequence rule is add 8 starting
Alchen [17]

Answer:

36

Step-by-step explanation:

the first sequence starts

4 12 (3*4) 36 (3*12) 108 (3*36) ...

the second sequence starts

20 28 (8+20) 36 (8+28) 44 (8+36) ...

so, just by writing down a few elements you can see it already.

I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"

What is the value of r (3,4), (-1,r),m=-3/4
Llana [10]

To find the value of r

We will follow the steps below

Usinf the equation of a slope:

slope(m) =

m=\frac{y_2-y_1}{x_2-x_1}

from the question given;

m= -3/4

x₁ = 3

y₁=4

x₂=-1

y₂=r

substituting the values into the slope formula

\frac{-3}{4}\text{ = }\frac{r-4}{-1-3}

we can now simplify and then solve for r

\frac{-3}{4}\text{ = }\frac{r-4}{-4}

cross-multiply

-3 x -4 = 4(r-4)

12 = 4(r-4)

Divide both-side of the equation by 4

\frac{12}{4}\text{ = }\frac{4(r-4)}{4}

3 = r - 4

add 4 to both-side of the equation

3+4 = r-4+4

7 = r

r=7

Therefore the value of r is 7
