The maximum number of toppings they can put on their pizza is 4 toppings because since she has 15 dollars and she needs 11.50 to buy the pizza, 15.00-11.50=3.50. She will have 3.50 dollars to spend on toppings. So, 3.50 divided by .75 is 4.
Answer:
20*pi/3
Step-by-step explanation:
Arc length = Radius * central angle of the arc (in radians). The figure shows that the unit arc angle is 4*pi/3. Multiply that by the 5 ft results to 20*pi/3.
Answer:
-15,-13,-11
n + (n+2) + (n+4) = -51
3n + 6 = -51
3n = -57
n = -19
-19,-17,-15
Step-by-step explanation:
Answer:
50; 72; 8; 57.9
Step-by-step explanation:
1. sqrt((30/2)^2 + (20)^2) = sqrt(15^2 + 20^2) = sqrt(225 + 400) = sqrt(625) = 25 (radius) * 2 = 50 (diameter)
2. 360 (degrees in a circle)/5 (sides in a pentagon) = 72 degrees
3. 360 (degrees in a circle)/x (sides) = 45 --> 360/45 = x --> 8 sides = x
4. sqrt(7^2 + (12/2)^2) = radius --> sqrt(49 + 36) --> sqrt85 * 2pi = circumference --> 57.9281062 = circumference --> 57.9
We need to solve the system of equations here.
Our main objective is to remove one of the variables.
To do so we can multiply the second equation by 2 and get 2x+4y=-8
Then we can subtract our new equation from the earlier one and get -5y=21
thus we know y=-21/5=-4.2
we plug that back into the equation and find x
2x-(-4.2*3)=13
2x=25.6
x= 12.8
so the solution is 12.8,-4.2
