What is the value of the expression 6+18÷3×4

Answers

Hi! Ok so you use PEMDAS to figure these out. 
So first we can cancel out parenthesis and exponents since there are none in this equation.
Now we do multiply and divide from left to right.
So first 18/3=6
So 6+6*4 
Now we do 6*4=24
Now add and subtract
Then 6+24=30
So your answer is 30
it would be 30 cuz of the PEMDS 
18 ÷ 3 =6 
3 × 4 = 24 
24 + 6 =30

it takes 10 workers 5 days to complete a road repair when working 2 hours a day. working at the same pax’s how many days will it take 2 people working 5 hours a day to finish it?

Answers

It takes 10 workers 5 days to complete a road repair when working 2 hours a day.

So, this becomes : 2*5*10=100 man hours required to finish the work.

Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d

So, total man hours = 2*5*d=10d

Now, 10d=100 or d=10

Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.

It will take 10 days for 2 people working 5 hours a day to finish the road repair.

Further Explanation:

From the question;

10 workers can finish road repair in 5 days working 2 hours a day

We need to find;

The number of days required to complete the road repair by 2 workers  working 5 hours a day.

Assuming the number of days required to complete the work is x

Number of working hours of 10 people is 10 hours ( 2 hours a day for 5 days)

Number of working hours of 2 people is 5x hours (5 hours a day for x days)

Note that; the number of workers or people is inversely related to the number of working hours.

Therefore;

Product of number of people and working hours or work done is a constant

Thus;

10 × 10 =  2 × 5x

100 = 10 x

x = 10

Therefore;

2 workers working 5 hours a day will require 10 days to complete the road repair.

Bryce bought a bag of cashews.he served 7/8 pound of cashews at a party. This amount represents 2/3 of the entire bag. The equation 2/3n =7/8 can be used to find the number of pounds n in a full bag how many pounds of cashews were in the bag Bryce bought?

Answers

ok so for this problem you you divide 2/3 n by 2/3 and 7/8 by 2/3
you get n= (7)/(8) / (2)/(3)
to divide fraction you flip the divider over to find the reciprocal
2/3 > 3/2 also you change the division symbol to the multiplication symbol
the equation now is n= (7)/(8) * (3)/(2)
now you multiply to get 21/16 
the answer is 1 5/16 after you simplify it

Answer: Hello there!

We know that 7/8 lb is equivalent to 2/3 of the entire bag, then the equation to find the number of pounds in the original bag is:

(2/3)*n = 7/8lb

and we want to find the number n.

The first step is divide both sides of the equation by 2/3 (or multiply both sides by 3/2 )

then

(3/2)*(2/3)*n = (3/2)*(7/8)lb

n = (3*7)/(2*8)lb = 21/16lb

now we can "break" the 21 in 16 + 5

n = (21/16)lb = (16 + 5)/16lb = (1 + 5/16)lb

What’s the cot(180°) + (cos(180°)/sin(180°))

Answers

Answer:

the answer is 'undefined'

Step-by-step explanation:

Cot is defines as (cos x)/(sin x)

So we can rewrite our expression as...

(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)

or

2(cos 180°)/(sin 180°)

Cos 180° = 1, sin 180° = 0   (you get these from the unit circle)

so we have

2(1/0) = 2/0,  which is undefined, because we don't divide by zero
