R+4 is the algebraic expression for your answer
Answer:
1/2 x
Step-by-step explanation:
Let
x-------------> pounds of granola-----------> <span>$3 per pound
</span>y-------------> pounds of raisins-----------> $2 per pound
z------------ > price per <span>pounds of the trail mix
</span>
we have that
z=3x+2y--------------------- > this is the equation
for x=3 pounds of granola and y=<span>0.75 pounds of raisins
z=3*3+2*0.75=</span>$10.5 of <span>trail mix</span>
Answer:
565.2cm
Step-by-step explanation:
Since we need to find out the circumference because the radius of the tire is 30cm. We take 30cm times 2. Which we get 60cm, then we take 60cm times 3.14 to get the circumference of 188.4cm. Then we take 188.4cm times 3 full rotations to get 565.2cm.
The answer would be 3.7406 × 10^17. Because when multiplying the constant you would get 37.406 and then you add the exponent and add one more since only one decimal can be over the decimal.
