Step-by-step explanation:
20a + 158+6c=you will expand the brackets
= so it is 120+60+48
20a+158+6c=120+60+48
20a+ 6c=120+60+48-158
20a+6c=70
20a divide by 20+6c divide by 6 on both side
a + c = 0.58
what is the answer of 5ax +8ax+6ax=?
All have ax included so add the numbers together.

A, B, and C lie on a straight line.
Given that angle y= 118 degrees and angle z =107 degrees work out x.
Step-by-step explanation:
m∠B = 180° - y°
= 180° - 118°
= 62°
x° = 180° - (m∠B + z°)
x° = 180° - (62° + 107°)
x° = 180° - 169°
x° = 11°
i don't know, it was correct or no. Because i thought this question is looking for the valuable of x.

Joe has $70 in a savings account. The interest rate is 10% per year and is not compounded,
How much interest will he earn in 4 years?
Use the formula i = prt, where / is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$28
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 70 × 0.1 × 4 = 28
I = $ 28.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 10% per year
for 4 years is $ 28.00.

The answer is in the simplest form already.
Rewrite the equation:
2 + 1/2 - 9 - 5/6
2 - 9 = -7 (negative 7)
1/2 minus 5/6 = ?
Find LCD of 1/2 and 5/6 and rewrite to solve.
3/6 is the LCD, so:
3/6 - 5/6 = -2/6
-2/6 = -1/3
So, the answer is:
-7 -1/3 = 7 1/3

Maybe it looks like this?
Step-by-step explanation:
The mass of a dust particle is approximately 7.5 x 10 –10kilograms and the mass of an electron is 9.1 x 10 –31kilograms. Approximately how many electrons have the same mass as one dust particle?
Answer:
(7.5 x 10-10 kg) / (9.1 x 10-31 kg) ≅ 8.24 x 1020
Step-by-step explanation:
Divide the mass of one dust particle by the mass of one electron, and that will be your answer.
(7.5 x 10-10 kg) / (9.1 x 10-31 kg) ≅ 8.24 x 1020

the measurement is 4 and 6 what is the perimeter.
Answer:
P=16 cm.
Step-by-step explanation: it is 16 inches
Answer:
To find the perimeter, you do 2 x length + 2 x width
So it would be, 2x4 + 2x6 = 20 inches
You didn't measure properly!!!
Personally, I think you meant to write 3 and 5, that would make 16
in a major study by the statistics classes at Washington High School, city parking spaces were examined for compliance with the requirement to put money in the parking meters. Overall, the students found that 76% of metered parking places had meters that had NOT expired, and 24% had meters that were expired. If the traffic officer in charge of ticketing cars with expired meters checks meters at random, what is the probability he will find an expired meter BEFORE the 3rd one
Answer:
0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one
Step-by-step explanation:
For each car, there is a 24% probability that it had expired parking meters.
What is the probability he will find an expired meter BEFORE the 3rd one?
Three possible outcomes:
Two expired(each with 24% probability)
First expired(24% probability) and second not(76% probability)
First not(76% probability) and second expired(24% probability). So
[tex]p = 0.24^2 + 2*0.24*0.76 = 0.4224[/tex]
0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one

Answer:
1,563.5 in³904.8 yd³2,144.7 mm³1,288.2 cm³434.9 in³Step-by-step explanation:
The formula for the volume of a sphere is ...
V = (4/3)πr³
When you have several of these calculations to do, it is convenient to let a graphing calculator or spreadsheet do them. A spreadsheet can do the rounding for you, too. The results are attached. The units are the cube of the units of the radius.
Example calculation:
(4) Radius = diameter/2 = 13.5 cm/2 = 6.75 cm
V = (4/3)π(6.75 cm)³ = 4.18879 × 307.547 cm³ = 1288.2 cm³
Note that the constant (4/3)π ≈ 4.18879 remains the same for each calculation. All you need to do is multiply that by the cube of the radius.

Answer:
Last option is the correct answer
Step-by-step explanation:
None of these choices are correct.
Correct order would be,
Since,
58° < 59° < 63°
Therefore,
AC < CB < AB
AC, CB, AB (this is the correct order of the sides from shortest to longest.)
