187÷20=??
Plz help me and plz show your work.
Answer:
9.35
Step-by-step explanation:
This is a simple division problem all you have to do is 187 by 20 to get 9.35
Answer:
9.35
Step-by-step explanation:
In order to solve this, we need to use a method called long division. Long division is dividing but on a bigger scale. You would set up the problem like this:
187 ÷ 20
Now you see how many times 20 goes into 187.
Since it goes into 187 9 times, we know that our whole number is going to be 9. You would then need to figure out how many times 2 goes into 7. Because 2 goes into seven 3 1/2 times, we can now put our answer together. 9.35 is the answer.
You could also just use a calculator. Using a calculator would be much faster and simpliler.
I hope this helps. Please let me know if you need any more help. Have a great day!

A retail ice cream salesman divides his working days into 'sunny', 'medium', and 'cold'. He estimates that the probability of it being sunny is 0.2, and cold 0.3. If his gross sales on these three types of day are $50, $35, and $10 respectively on average and his average daily costs are $18 on any day.
Required:
a. Complete the probability distribution.
b. Find his expected profit per day.
Answer:
30.5
Step-by-step explanation:
Let ;
Sunny = S ; Medium = M ; Cold = C
_____ S _____ M ___ C
__X : 50 ____ 35 ___ 10
P(X) : 0.2 ____ 0.5 __ 0.3
P(M) = 1 - (0.2 + 0.3)
P(M) = 1 - 0.5 = 0.5
Expected profit per day, E(X)
E(X) = sum of (X * p(x)
E(X) = (50 * 0.2) + (35 * 0.5) + (10 * 0.3)
E(X) = 10 + 17.5 + 3
E(X) = 30.5

Answer:
ACB=44°
DCE=35°
BCD=101°
Step-by-step explanation:
ACB is a triangle and all triangles are 180 degrees
78+58=136

DCE is also a triangle
85+60=145
180-145=35
a straight line is 180 degrees, we already know what the other two is.
35+44=79
180-79=101

The school has 6 rows of lockers. Each row has 35 lockers. For the first 5 rows, all of locker are taken. For the last row, 3/5 of the locker are taken , 3/4 of all locker that are taken have decorated name tag. How many locker at school have decorated name tags.
a) 145
b) 141
c) 143
d) 147
The number of locker at school have decorated name tags is 147. Therefore, option D is the correct answer.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, the school has 6 rows of lockers. Each row has 35 lockers.
For the first 5 rows, all of locker are taken.
Number of lockers in 5 rows are 35×5=175
For the last row, 3/5 of the locker are taken is
3/5 ×35 =21
So, the total number of lockers taken = 175+21
= 196
3/4 of all locker that are taken have decorated name tag
Now, 3/4 ×196
= 3×49
= 147
Therefore, option D is the correct answer.

The answer is 69.5
Step-by-step explanation:
First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52
meanwhile triangle is 5ft tall and the base is 7ft
using the formula to solve for area of a triangle you would multiply height and base and divide by 2
you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

Ralph opened up his checking account with $100. On Monday, he withdrew $45 to purchase a pair of jeans. On Wednesday, he deposited a $25 check he received for his birthday from his uncle. On Friday, he used his debit card to buy a $98 football ticket. What is the balance in Ralph's checking account?
Answer:
The answer is -18
Step-by-step explanation:
He starts off with $100 in his account. He then take so $45 to purchase a pair of jeans, so we have to subtract 45 from 100 and that gives us $55. He now has $55 in his account, he then adds another $25 to his account, so we have to add 25 to 55 and that will give us $80 in his account. Finally on Friday he takes out $98 of his checking account. He takes out more than he has in his checking account so we have to subtract $80 from $98 and we will get $18, but since he takes out more than what he has in his account the answer will be negative and we end up with -18 dollars in his checking account.
