Number of male students with X hair + Number of female students with X hair = Total number of students with X hair
(where X is any hair color)
Number of Y students with brown hair + Number of Y students with blonde hair + Number of Y students with hair of another color = Total number of Y students with any hair color
(where Y is either male or female)
Total number of male students + Total number of female students = Total number of students with brown hair + Total number of students with blonde hair + Total number of students with hair of another color = Total number of students overall
There are 39 total students. 21 of them are female. So 39 - 21 = 18 of them are male.
13 students had brown hair. 11 had blonde hair. So 39 - 13 - 11 = 15 had hair of another color.
13 students had brown hair. 5 male students had brown hair. So 13 - 5 = 8 female students had brown hair.
11 students had blonde hair. 4 female students had blonde hair. So 11 - 4 = 7 male students had blonde hair.
18 students are male. 5 had brown hair and 7 had blonde hair. So 18 - 5 - 7 = 6 of them had hair of another color.
21 students are female. 8 had brown hair and 4 had blonde hair. So 21 - 8 - 4 = 9 of them had hair of another color.
Put all this into the table (see attached).
Answer:
y= 0.05x + 50
Step-by-step explanation:
Slope intercept form: y= mx + b
The total monthly cost of the telephone plan is $50 plus a charge of $0.05 per minute.
The charge is <em>dependent</em> on the minutes used.
Whenever we see <em>per</em>, we automatically have our slope.
Slope: 0.05
And since 50 is the <em>independent</em> variable, 50 is our y-intercept.
y= 0.05x + 50
Answer:
No.
Step-by-step explanation:
A proportional equation has no added constant. It is of the form ...
... y = kx
for some constant k. (0, 0) is always a solution to a proportional equation.
I had a problem similar to this and the ratio would be 1:2 ratio or half in fraction form
Answer:
<u>$16.74</u> will be paid for the chips.
Step-by-step explanation:
Given:
A 40-pack of Doritos cool ranch chips costs $25.75.
It's on sale at 35% off.
Now, to find the price to pay for the chips.
Cost of chips = $25.75.
Sale = 35% off.
According to question:
Thus, to get the cost of chips on sale at 35% off:
<u><em>$25.75 - 35% of $25.75.</em></u>
Therefore, $16.74 will be paid for the chips.
