Answer:
$6.30
Step-by-step explanation:
First, get the volume of the cereal box with the equation V = lwh.
V = 7(3)(10) = 210 cubic inches
Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.
.03(210) = $6.30
Answer:
the number should be 7
Step-by-step explanation:
7 times 5 eqauls 35. 35 minus 9 equals 26. if you add 7 and 19 you get 26.
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)
Answer:
x= -2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
