Answer:
10
Step-by-step explanation:
When the equation says that Jill bikes 2/3 hour at 18 mph, it means that the amount of miles she biked is 2/3 of 18. 18 divided by 3 is 6. 6 times 2 is 12, so she biked 12 miles. If she walks 2/5 hour at 5 mph, then she walked 2 miles because 5 divided by 5 is 1 and 1 times 2 is two. The question is asking how much more she biked than walked, so 12-2=10.
Hello :
the area is : A=<span>πr²
</span> π ≃ 3.14 r : <span>ridus
</span> <span>diameter = 2 r
</span>r = 18/2= 9 ft
A=3.14×9² = 254.34 ft²
Answer:
1) x=67, y=83, z=80 2) x=5
Step-by-step explanation:
1) 28+85=113 a triangle is 180 degrees so 180-113=67 so x=67
x and y are supplementary meaning both sides equal 150 so 150-67=83
83+17=100 now going back how much did i say a triangle should equal? 180 so z is 80
2)a triangle = 180 since the triangle is a right angle it includes the angle 90 so make the equation to solve for x
180=90+8x+2+9x+3
take 90 to other side so you are subtracting 180-90
90=8x+2+9x+3
combine like terms
90=17x+5
subtrcat 5 from 90
85=17x
now divide 85 by 17 and you get x=5

The Webster family is planning a barbecue for one hundred people. The Webster family needs one plastic plate for each person at the barbecue. The Stop and Shop store and Market Place Store both sell plastic plates in packages of fifteen for five dollars and ninety-nine cents per package. How many packages of plastic plates does the Webster family need to buy? What is the cost of plates for the barbecue?
Answer:
-The Webster family needs to buy 7 packages.
-The cost of the plates is $41.93.
Step-by-step explanation:
To calculate amount of packages that the Webster family need to buy, you have to divide the amount of people by the number of plates in each package:
100/15= 6.66
According to this, as they will need more than 6 packages, the Webster family needs to buy 7 packages to have one plastic plate for each person at the barbecue.
Then, the cost of the plates for the barbecue would be calculated by multiplying the price of each package for the number of packages needed:
$5.99*7= $41.93
The cost of the plates is $41.93.
Answer: Y= 86 X=94
What I did is, the angle minus 86 to give me 94
