Step-by-step explanation:

just add all the given angles and equate it with 540° and then find x

x/2 + x/2 + x - 25 + 100 + x - 15 = 540°

3x + 60 = 540°

3x = 540 - 60

x = 480/3

x = 160°

on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.

Answer:

1/8, 0.0625 , or 6.25%

Step-by-step explanation:

50% of the cars are painted white.

1/2 * 1/2 = 1/4 * 1/4 = 1/8

Probability of A occuring 4 time(s) = 0.54 = 0.0625

Probability of A NOT occuring = (1 - 0.5)4 = 0.0625

Probability of A occuring = 1 - (1 - 0.5)4 = 0.9375

Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv

dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

$Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour$

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

$s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours$

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

A salesman is paid a salary of $2500 per month and a commission of 10% on all sales above $7000. Calculate his gross salary if h

Verizon [17]

Answer:

$4150

Step-by-step explanation:

Given data

Salary= $2500

Commission= 10%

Sales= $16500

Let us find the amount of the commission made

=10/100*16500

=0.1*16500

=$1650

Hence the total amount made for the month is

=commission + salary

=1650+2500

=$4150
