Using Pythagoras:-
x^2 = 6^2 + (sqrt18)^2
= 36 + 18 = 54
x = sqrt54 = 3 sqrt6
Given:
Latasha spends $3.35
Helen spends 4 times as much as Latasha.
Dee spends $7.50 more then Helen.
To find:
The amount Dee spends.
Solution:
It is given that, Latasha spends $3.35.
Helen spends 4 times as much as Latasha.
So, Helen spends = 4 × $3.35
= $13.40
Dee spends $7.50 more then Helen.
Dee spends = $13.40+$7.50
= $20.90
Therefore, dee spends $20.90.
Since we are finding the unit rate of the cost per comic, we will need to divide $5 by 20 comics which you will get 0.25 cents and divide $7.50 by 30 comics which you will also get 0.25 cents.Therefore, the unit rate and constant of proportionality is 0.25 cents.
X and Z equal 72
Y equals 108.
This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
Answer:
x + y = 330 and 9x + 16y = 4650
Step-by-step explanation:
At a museum, the admission price for children is $9 and the admission price for adults is $18. The total amount the museum collects in admissions for the day is $4959. The total number of visitors is 319.
x = number of children
y = number of adults
x + y = 330
9x + 16y = 4650
