I believe the answer is 13. You would take x from both sides, then add four plus nine. Hope this helps, have a nice day
A(base)=6*6=36
A( triangle)=1/2*(base of the triangle)*height( of the triangle)=1/2*6*4=12
one base +4 triangles=36+4*12=36+48 =84 cm²
Answer:
2m+4 is the answer
Step-by-step explanation:
Total time taken by Sam before Al caught up with him = 15+10 = 25 minutes
In hours = 25 minutes = 25/60 = 5/12 hrs
Distance covered by Sam = Distance covered by Al = Speed (Sam) * time taken = 3.2*5/12 = 4/3 miles.
Al takes 10 minutes to cover that distance. Therefore,
Al's speed = Distance/time = (4/3)/(10/60) = (4/3)*(60/10) = 8 mph
Answer:
Part 1) 2.1 cups of cream
Part 2) 4.2 cups of dark chocolate
Step-by-step explanation:
we know that
The recipe for 20 chocolate truffles is:
I cup of cream
2 cups of dark chocolate
step 1
Find how many cups of cream are needed for 42 truffles
using proportion
Let
x-----> the number of cups of cream needed
20/1=42/x
x=42/20=2.1 cups of cream
step 2
Find how many cups of dark chocolate are needed for 42 truffles
using proportion
Let
x-----> the number of cups of dark chocolate needed
20/2=42/x
x=42*2/20=4.2 cups of dark chocolate
