John works as a tutor for an hour and as a waiter for an hour. This month, he worked a combined total of hours at his two jobs.
liberstina [14]

Correct Question:

John works as a tutor for $12 an hour and as a waiter for $8 an hour. This month, he worked a combined total of 86 hours at his two jobs.

Let be the number of hours John worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.

Answer:

Total hours = 86

Let t is the hours he spent on tutoring

then (86-t) is hours spent on waiting

Let Y is the total amount in dollars which is required .

Now;

y = (tutoring hours x 12$) + (waiting hours x 8$)

Y = 12t + 8(86-t)

Can someone plz do the dimensional analysis for 32ft/6.45 sec to meters/min? Thank You!
Rzqust [24]

Answer:

About 90.73 meters/min.

Step-by-step explanation:

Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.

First, we will convert feet to meters, using that 1 ft = .4048 m.

32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.

Second, we convert seconds to minutes, using that 60 sec = 1 min.

9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.

Find the area of the polygon
antoniya [11.8K]

Looks like the larger triangle is equilateral (well, it must be, otherwise finding the area is impossible). That means the inradius is 6 and the outradius is 12, which is to say the altitudes (equal to the height, in this case) of this triangle have length 6 + 12 = 18.

In the smaller right triangle, the length of the missing leg is half the base of the larger triangle; call this length \frac b2 By the Pythagorean theorem,

6^2+\left(\dfrac b2\right)^2=12^2\implies b=12\sqrt3

Then the area of the larger triangle is

\dfrac12(12\sqrt3)(18)=\boxed{108\sqrt3}

I need help please.
Natali5045456 [20]

Answer:

=11/4  cm

Step-by-step explanation:

We are finding the perimeter

P = 2(l+w)

l = 3/4 cm

w = 5/8 cm

The common denominator is 8

l = 3/4 *2/2 = 6/8

P = 2(6/8+5/8)

  =2(11/8)

   =22/8

    =11/4  cm  (2 1/4 cm)

It says an integer or a fraction, not a mixed number
