Answer:
$12.25
Step-by-step explanation:
1.6 ounces of cinnamon sticks and 9.4 ounces of cocoa. The equation for this would be 3.25s + 0.75c = t, where s is the amount of cinnamon sticks, c is the amount of cocoa, and t is the total price.
3.25s + 0.75c = t
3.25(1.6) + 0.75(9.4) = t
5.2 + 7.05 = t
12.25 = t
The total price is $12.25.
Answer:
X=6 and Y=3
Step-by-step explanation:
Use SOHCAHTOA, SOH, Sin=Opposite/Hypotenuse, Therefore Sin60°=(3√3)/x ; Xsin60°=3√3 and Sin60° without using 4figuretable or calculator is √3/2, Now x=3√3 ÷√3/2 ;. therefore X=3√3×2/√3= 6. X=6 . Using Pythagoras theorem, 6²={(3√3)² +y²}. Y²= 36-27=9. Y=√9, Y=3. Therefore X=6 and Y=3.
Answer:
He must need to work 13 hours or 14 hours for lifeguarding.
Step-by-step explanation:
Consider the provided information.
Let x represents the number of hours for babysitting.
y represents the number of hours for life-guarding.
In a given week, he can work at most 17 total hours and must
Juan is working two summer jobs, making $12 per hour babysitting and making $16 per hour lifeguarding. He must earn at least $240.
If Juan worked 3 hours babysitting,
Substitute x=3 in
Thus, he can work at most 14 hours for lifegurading.
Substitute x=3 in
Therefore, he must need to work 13 hours or 14 hours for lifeguarding.
