488/7
Look at the first digit of the dividend. Is there a factor that can be subtracted?
-Not, really so we go to the second digit. Now we're looking at the number 48.
Is there any factor that multiplies by 7 that can be subtracted?
-Yes, and that's 6.
Now you do 48-42=6 and drop down the remaining digits in the dividend.
- You are left with 68
Ask yourself again, is there any factor i can multiply by 7 that can be subtracted?
-Yes, and thats nine.
Subtract again and you are left with 5.
Since there's no more number from the dividend to drop down, you put a zero and keep multiplying.
i've ran outta time so the answer is : 69.7142857143
Hope you understood what i wrote.
Answer:
9cm
Step-by-step explanation:
Area of trapezium=(1/2)×(a+b)h
A=33
a=2
b=?
h=6
(1/2)(2+b)(6)=33
(1/2)(12+6b)=33
6+3b=33
3b=33-6
3b=27
b=27÷3
b=9
Answer: I believe his earnings would be 187$ once he teaches 7 classes.
Step-by-step explanation:
$187-$68=$111
17 x ? = 119
(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:
$111/17$=$6.5 (round to $7)
(you then plug in the 17 for 7 x ? = 119)
7x17=119
now you have to add the 68$ that he will get per month.
119+68=187
then you get 187$ which he had spent on the certificate
T = kh where t = tons and h = hours, k is the constant of variation
This is direct variation.
27 = k*3
= 27/3 = 9
Equation of variation is t = 9h
Amount produced in 8 hours t = 9*8 = 72 tons Answer
