Answer:
278 tons
Step-by-step explanation:
Given data
Train A and Train B, weigh a total of 366 tons
A+B= 366----------1
We are also given that
A-B= 190-----------2
from 1
A= 366-B
put this in equation 2, we have
366-B-B= 190
366-2B= 190
366-190= 2B
176=2B
divide both sides by 2
B= 176/2
B=88 tons
Put B= 88 in equation 1 to find A
A+88= 366
A= 366-88
A=278 tons
Hence Train A is 278 tons

A circular running track is 14 of a mile long. Elena runs on this track, completing each lap in 116 of an hour. What is Elena’s running speed? Include the unit of measure
Answer:
The wording is quite confusing, but here it goes
Step-by-step explanation:
T(track)= 14 of a mile. 1 mile is 5280 feet. If Elena is running each lap at 116 of an hour, (116%?) then 16% of 60 is 9.6 minutes, so each lap takes 69.6 minutes. One lap is 1312 feet, so 5280/1312= 4.02, so she can run 4 laps, which will take her 278 minutes. So 1312 is 24% of a mile, and she is running at .24 mph.
A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign in square inches?
81.64 in.²
163.28 in.²
530.66 in.²
2,122.64 in.²
Answer:
i think 81.64
Step-by-step explanation:
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
What is the area of a circle?The area of the circle is pie times the square of the radius of a given circle.
The area of the circle = [tex]\rm \pi r^{2}[/tex]
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\rm \pi r^{2}[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Toko sepatu memberi diskon 30% untuk semua barang.Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon,harga sepasang sepatu tersebut sebelum diskon adalah
Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000
