Answer:

4 miles

Step-by-step explanation:

Let

x ----> the time to returned back biking in hours

d ---> the distance in miles

s ---> speed in miles per hour

Remember that

The speed or rate is equal to divide the distance by the time

$s=\frac{d}{t}$

The distance is equal to multiply the speed by the time

$d=st$

we know that

$18\ min=\frac{18}{60}\ hours$

The distance to his friend's house and the distance of return is the same

$10x=4(x+\frac{18}{60})$

solve for x

$10x=4x+\frac{18}{15}$

subtract 4x both sides

$10x-4x=\frac{18}{15}$

$6x=\frac{18}{15}$

$x=\frac{1}{5}\ hours$

The total distance of the round trip is

$y=10x+4x+\frac{18}{15}$

substitute the value of x

$y=10(\frac{1}{5})+4(\frac{1}{5})+\frac{18}{15}$

$y=2+2=4\ miles$

The blue ribbon would be 19 inches. We know the red ribbon is 12 inches and it’s 7 inches less than the blue one, so you would add 7 to 12 to figure out that the blue ribbon is 19 inches.

What is the 28% tax on a 600,00 cash prize?

konstantin123 [22]

•❋Let's start with the first step: Converting 28% into a decimal.
To do this you can multiply it by 100 which gives us .28.
Now we have $600.000 in cash and we need to then multiply it by .28.
.28*600=168.
Now we are going to subtract what we just got by the original amount $600.000
(we can also say that it is $600)
So $600-$168=$432
Now we have out answer
28% tax on a $600.000 cash prize = $432
•❋Hope this helps•❋

A 13.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck)

gladu [14]

Answer:

11.6m

Step-by-step explanation:

A 13.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck) if the ladder makes an angle of 59 22' with the horizontal.

We solve the above question using the Trigonometric function of Sine.

sin θ = Opposite/ Hypotenuse

Hypotenuse = Length of the ladder = 13.5m

Opposite = d

θ = 59° 22'

= 59° + 22/60

= 59° + 0.367

= 59.367°

Hence,

sin 59.367 = d/13.5m

d = sin 59.367 × 13.5m

d = 11.616057416m

Approximately = 11.6m

Therefore, the distance d the ladder goes up the wall is 11.6m

Where The Jou

natali 33 [55]

Answer:

$ 391

Step-by-step explanation:

It is mention in question that Mrs. Hollern earn 8.5% as commission for every piece of Necklace she sells

Now she sells a necklace cost $ 4,600.

so as per her commission she will take 8.5% of total necklace cost

Thus she will take 8.5 % of $4,600

I.e $\frac{8.5*4600}{100}$

Or, $\frac{39100}{100}$

Or, $ 391

So it is found that she will get $391 as commission .
