Weight=smallertotalweight+largertotalweight
smallertotalweight=weight times how many
largertotalweight=weight times how many
lets call them s and l
smaller and larger
650=50s+75l
and
550=100s+25l
simplfiy the m all by dividing by 5
130=10s+15l
110=20s+5l
divide by 5 again
26=2s+3l
22=4s+l
we can eliminate the s's
multiply first equatn by -2 and add to first
22=4s+l
<u>-52=-4s-6l +</u>
-30=0s-5l
-30=-5l
divide both sides by -5
6=l
input back
22=4s+l
22=4s+6
minus 6
16=4s
divide 4
4=s
each smaller model weighs 4 pounds
larger weighs 6 pounds
Use pythagorean theorem a² + b² = c², where a and b are legs, and c is hypotenuse.
9² + 40² = c²
√(9² + 40²) = c
√(81 + 1600) = c
√1681 = c
41 = c
So length of hypotenuse is 41 cm.
Answer: 16 ounce
Step-by-step explanation:
16 ounce is 1.17 per ounce but 7 ounce is 1.19 per ounce in real life the bigger is usually a better deal anyway
Answer:
i think it is E
Step-by-step explanation:
The length of the band in terms of π is given by the expression:
L = 40mm + π*10mm
<h3>
How to get the length of the band?</h3>
Remember that for a circle of diameter D, the circumference is:
C = π*D.
Now, if you look at the image, you can see that the length of the band will be equal to 4 times the diameter of the pencils (one time for each side). Plus 4 times one-fourth of the circumference of each pencil (for the four corners).
because the diameter is 10mm, the length of the band will be:
L = 4*10mm + 4*(π*10mm/4)
L = 40mm + π*10mm
This is the length of the band in terms of π.
