What is -1/2(-4/5) multiplied then in simplest form?

olchik [2.2K]

-1/2(-4/5)

Multiply the numerators by each other and do the same for the denominators.
That is:
-1(-4)=4
And 2*5=10

Now we have 4/10
Divide the numerator and the denominator by 2 to get 2/5 which is the simplest form.

Hope this helped.

Vinil7 [7]

Answer:

$270.3\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ADE

Find the value of h1

See the attached figure

h1=AD

$tan(25\°)=\frac{h_1}{180}$

Solve for h1

$h_1=(180)tan(25\°)\\h_1=83.94\ ft$

step 2

In the right triangle ABC

Find the value of h2

See the attached figure

h2=BC

$tan(46\°)=\frac{h_2}{180}$

Solve for h2

$h_2=(180)tan(46\°)\\h_2=186.40\ ft$

step 3

Find the height of the neighboring building

we know that

The height of the neighboring building is equal to

$h=h_1+h_2$

substitute the values

$h=83.94+186.40=270.34\ ft$

Round to the nearest tenth of a foot

$h=270.3\ ft$

A wild horse runs at a rate of 8 miles per hour for 6 hours. Let yy be the distance, in miles, the horse travels for a given amo

spin [16.1K]

Answer:

$0\leq x\leq 6$

$0\leq y\leq 48$

Step-by-step explanation:

we are given

speed =8 mph

time = 6 hours

so, we have

$x=6$

now, we can find distance

distance = (speed)*(time)

$distance=8\times 6 miles$

$distance=48 miles$

so, we have

$y=48 miles$

so, our range for x and y can be

$0\leq x\leq 6$

$0\leq y\leq 48$
