Two cars are traveling in the same direction. The first car is going 40mph, and the second car is going 55 mph. The first car left 3 hours before the second car. Which equation could you use to find how many hours it will take for the second car to catch up to the first car? hint: how many miles has the first car gone in those 3 hours?

Answers

Answer 1

Assuming both cars start at the same position, in the first 3 hours the first car covers a distance of

(40 mi/h) (3 h) = 120 mi

Take the 3 hour mark to be the origin, so that the first car's position after t hours is

120 mi + (40 mi/h) t

while the second car's position is

(55 mi/h) t

The second car catches up to the first when their positions are equal:

120 mi + (40 mi/h) t = (55 mi/h) t

120 mi = (15 mi/h) t

t = (120 mi) / (15 mi/h)

t = 8 h

Blake: 62 x 120 = 7,440

8,880 - 7,440 = 1,440

Answer:

Step-by-step explanation:

A function can be represented verbally. For example, the circumference of a square is four times one of its sides.

A function can be represented algebraically. For example, 3x+6 3 x + 6 .

A function can be represented numerically.

A function can be represented graphically.

Using what you noticed, find the measures of the four angles at point B in this second diagram. Lines AC and DF are parallel.

Answers

Answer:

The measures of the four angles at B are

m∠EBC = 34°

m∠ABH = 34°

m∠EBA = 146°

m∠CBH = 146°

Step-by-step explanation:

∵ AC // DF

∵ HG is the transversal

∴ m∠GEF = m∠EBC ⇒ corresponding angles

∵ m∠GEF = 34°

∴ m∠EBC = 34°

∵ GH intersects AC at B

∴ m∠EBC = m∠ABH ⇒ vertically opposite angles

∵ m∠EBC = 34°

m∠ABH = 34°

∵ B ∈ AC

∠EBC and ∠EBA formed a pair of linear angles

∵ The sum of the measures of the pair of linear angles is 180°

m∠EBC + m∠EBA = 180°

→ Substitute m∠EBC by 34°

∴ 34 + m∠EBA = 180

→ Subtract 34 from both sides

∵ 34 - 34 + m∠EBA = 180 - 34

m∠EBA = 146°

∠EBA and ∠CBH are vertically opposite angles

∴ m∠EBA = m∠CBH

∵ m∠EBA = 146°

m∠CBH = 146°

I need help! Find the equation of a line parallel to 3x-3y=5 that contains the point (-1,-5). Write the equation in slope Intercept form.

Answers

the equation of the line is y= x-4

Step-by-step explanation:

so so the first thing that you're going to do is get y alone

-x-5=y

next you're going to find your slope which in this case is negative one.

after that in order to find the equation of a parallel line you're going to find the reciprocal of the slope.

so in this case the reciprocal is one.

next you're going to substitute in the cordinates to find the y intercept

x+b=y. (-1)+b= -5. (. b is the y intercept)

b= -4

Find sec A.​

Answers

9514 1404 393

Answer:

  sec(A) = -(1/5)√74

Step-by-step explanation:

Solving the equation for y, we have ...

  -7x = 5y

  -7/5x = y

The slope of this line (-7/5) is the tangent of the angle (A) it makes with the x-axis. The secant satisfies the relation ...

  sec(A)^2 = 1 + tan(A)^2

  sec(A) = √(1 +tan(A)^2)

  sec(A) = -√(1 +(-7/5)^2) = -√(74/25) . . . . secant is negative in 2nd quadrant

  sec(A) = -(1/5)√74

Answers

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°
