Answer:
(1/5)·100
Step-by-step explanation:
The number of jasmine flowers is 1/5 of the total number of flowers, so an expression for the number that are jasmine is ...
1/5×100
Answer:
45
Step-by-step explanation:
to figure this out you put 40/100 and 18/x then you cross multiply so 40x = 1800 then 1800 divided by 40 would be 45
Answer:
B
Step-by-step explanation:
180°= straight line
180°-42°=138
Answer:
Option B. 7
Step-by-step explanation:
In order to solve this question we first have to find out what is the difference between the prices of a pen and a pencil. SO we get...
60 - 4- = 20 cents
Now if we were to assume that all 17 items were pencils then Diane would pay....
17 x 0.40 = $6.8
But then he pays 8.2-6.8 = $1.4 less than he should be.
If we substitute one pencil with a pen the total will increase by 20 cents. From here we can easily get the number of pens by doing the following...
1.4 / 0.2 = 7 pens
Therefore option B is the right answer.
1) Since it was 0 years when the college opened, we put x=0 and we get
T=12000
2) 0.03%
3) From 1990 to 2020, it is 30 years. Thus, x=30.
T=12000*(1.03)^30
For calculations for the 2nd point, refer to the picture.
Hope this helps!
For future whenever you solve these type, just know that x is a variable and tree have to insert out own value for x according to the questions’s demand.
