Answer:
Step-by-step explanation:
1680 mile road trip....they completed 3/8 of it...
so we need to figure 3/8 of 1680
" of " in math language means multiply
3/8 * 1680 = 5040/8 = 630 miles <===
Answer:
D. diagonal = 20.10 cm
Step-by-step explanation:
Find the bottom diagonal using the length and width.
diagonal² = 8² + 12²
diagonal = √64+144
diagonal = √208
diagonal = 4√13
---------------------------------------------------------------------------------------------------------
Find diagonal of the rectangular solid:
diagonal² = (4√13)² + 14²
diagonal² = 208 + 196
diagonal = √404
diagonal = 20.10 cm
V=(4/3)pir^3
find smaller
V=(4/3)pi8^3
V=(4/3)pi512
V=(2048/3)pi
twice of that
Vbig=2*(2048/3)pi
Vbig=(4096/3)pi
find radius
(4096/3)pi=(4/3)pir^3
divide both sides by pi
(4096/3)=(4/3)r^3
times both sides by 3
4096=4r^3
divide both sides by 4
1024=r^3
cube root both sides
8∛2=r
aprox
10.0794
the answer you are looking for is 8∛2 or 10.0794in or something close to that
Ratios are fractions. Equivalent means equal, if you change one set of numbers, you have to change the second set of numbers so then that Ratio or Equivalent fraction stays equal on both sides.
Answer:
Distance = 70 + 55 = 125 kilometers
Time = 4 + 3 = 7 hours
Rate = Distance / Time
Rate = 125 / 7 = 17.8571428571 kilometers per hour
