Answer:
1) 3 miles/h
2) 3 miles
Step-by-step explanation:
6 miles/2h = 3 miles/h
4h = 12 miles
3h = 9 miles
12 - 9 = 3
Answer:
Company B is more likely to produce a box of 260 roofing nails.
Step-by-step explanation:
Company A :
Mean = 272 nails
Standard deviation = 5.4 nails
Roofing nails expected to be produced = 260
⇒ 260 = 272 + z × 5.4
⇒ z = -2.222
Hence, Company A has a chance of 1.32% of producing exactly or fewer than 260 boxes of roofing nails.
Company B :
Mean = 249 nails
Standard deviation = 3.8 nails
Roofing nails expected to be produced = 260
⇒ 260 = 249 + z × 4.8
⇒ z = 2.895
Hence, Company B has a chance of 0.19% of producing exactly or more than 260 boxes of roofing nails.
Therefore, Company B is more likely to produce a box of 260 roofing nails.
A triangles degrees add up to 180.
well first 180-138 for angle u which is 42
then do 42+(6y-2)+(8y+14)=180
solve for y.
42+(6y-2)+(8y+14)=180
42+6y-2+8y+14=180
54+14y=180
-54 -54
14y=126
/14 /14
y=9

Answer: Obtuse</h3>
This is because the lower left angle is larger than 90 degrees. This is assuming the triangle is drawn to scale (i.e. drawn accurately).
Any time there's an angle larger than 90, the triangle will be obtuse. If there's one angle exactly 90, then it's a right triangle. Otherwise, the triangle is acute (when all angles are smaller than 90).
Hello!
We must use a certain formula to find the area of a circle. The formula is:
A = pi * r^2
Since we already have the radius (21 cm) and we know what pi is (approximately 3.14), use the formula to solve:
A = 3.14 × 21^2
A = 3.14 × 441
A = 1,384.74
ANSWER:
The area of the circle is 1,384.74 centimetres squared.
