Okay, so you first make this proportion...
x=12x(4/6)=8 laps
answer: 8 laps
350 gallons for 9
Car with 15 gallons is 427.5 miles and a motorcycle with 5 is 320 so he is wrong
Answer:
Choice C
Step-by-step explanation:
x^2 +6x+8
what numbers multiply together to make 8 and add together to make 6
4*2 = 8 4+2 =6
(x+2) (x+4)
Choice C
You had the right idea using the Pythagorean theorem to solve for b.
Problem is for that triangle to work, the 5 and the 2√2 would have to switch places. The length of a leg cannot be larger than the length of the hypotenuse for it to truly be a right triangle.
Pythagorean theorem only works for the right triangles. Only way to "solve this problem would be to bring in complex numbers.
5² + b² = (2√2)²
25 + b² = 2²(√2)²
25 + b² = 4(2)
25 + b² = 8
b² = 8 - 25
b² = - 17
b = √-17
b= (√17i)
Then the problem with THIS is a measurement/distance cannot be negative... which goes against exactly what that complex number i is.
Answer:
<em>38.5 miles</em>
Step-by-step explanation:
We know that the distance between Mia's house and her aunt's house is 15.4 inches apart.
We also know that every 4 inches on the map represent 10 miles.
4 inches = 10 miles
Divide :
1 inch = 2.5 miles
Multiply the shown distance in the question by the amount of miles per inch
15.4 * 2.5
= 38.5 miles in total.
