Given:
Of the 50 students in the cafeteria, 7 have red hair.
Total number of students = 750
To find:
The proportion that could be used to predict the number of students who have red hair.
Solution:
Let x represent the number of students who have red hair.
The ratio of student having red hair to the total number of students are
The number of students having red hair is proportional to the total number of students. So, the above ratios are equal.
Multiply both sides by 750.
Therefore, the required equation is and the number of students who have red hair is 105.
I'm gonna do number 8 but do the SAME steps for the rest.....take the denominator multiply it by the whole number then add that answer to the numerator so now it will be 23/5×15/4 ... once u have that just multiply across but DON'T CROSS MULTIPLY multiply straight across and u'll get ur answer... answer to 8 is 345/20 now divide that answer like this.. 345÷20= 17.25
Answer:
1 because you can not buy 3/4 of a bag
Step-by-step explanation:
A. c + 7 ≤ 3
c ≤ -4
a = 2
b. c - 3 > 1
c > 4
b = 3
c. c - 7 < 3
c < 10
c = 2
Answer:
Basically if your spending like 10 minutes trying to understand that hand writing the question is asking for the formula you would use to find the distance and the ANSWER is <u><em>√(32-18)^2+(16-20)^2</em></u>
Step-by-step explanation:
Which im a very stubborn person and i tried to solve that language from NBG1 and it click, if you replace the variables from the Distance Formula then you will get the answer
But if you are trying to solve the distance then it will be <em><u>18.4</u></em> because you find the distance from the 3rd missing dot which will be( 18,16) and you will get <u><em>√(</em></u>4^2+18^18)
which will give you <u><em>√</em></u>340
<u><em>and you have to estimate to the nearest tenths which will be 18.4 </em></u>
