A toddler takes off running down the sidewalk at 270 ft/min. One minute later, a worried mother runs after the child at 580 ft/min. After how many minutes will the mother overtake the toddler?

Answers

Answer 1
Answer: we know that in one minute the toddler is 2(270)=540 feet and mother is 580 so less than 1 minute

Through any two points there is/are exactly ________ line(s).

Answers

Answer:  Only one line is the correct answer.

Step-by-step explanation:

Through any two points, there is exactly 1 line segment.

As the definition of line states that line segment has exactly two end points.

And postulate (3) of Euclid states that through any two points there is exactly one line.

And it can't be extended to any limit,

As it has only two end points.

Hence, only one line is the correct answer.

Answers

Answer:

Step-by-step explanation:               For any triangle, the angles add to 180 degrees

A+B+C = 180

68+46+C = 180

114+C = 180

C+114 = 180

C+114-114 = 180-114

C = 66

Angle C is 66 degrees

Angle C' is 66 degrees

The triangles ABC and A'B'C' are similar, so angle C = angle C'

Answer:

7m^(21)n^16 p^5

Step-by-step explanation:

This answer is found by diving exponents. You may be thinking its hard, but I promise you it is easier than it looks. First you look at exponent m and subtract 42-21 FIRST. that equates to 21 THEN you divide 21/3 which is 7m^21. There is only one answer with 7m^21

A software designer is mapping the streets for a new racing game. All of the streets are depicted as either perpendicular or parallel lines. The equation of the lane passing through A and B is -7x + 3y = -21.5. What is the equation of the central street PQ?See attachment below for picture/answer choices

Answers

Answer:

-1.5x-3.5y=-31.5

Step-by-step explanation:

we know that

If two lines are perpendicular

then

the product of their slopes is equal to minus one

so

m1*m2=-1

In this problem line AB and line PQ are perpendicular

Step 1

Find the slope of the line AB

The equation of the line AB is

-7x+3y=-21.5

isolate the variable y

3y=7x-21.5 ------> y=(7/3)x-21.5/3

The slope of the line AB is equal to

m1=7/3

Step 2

Find the slope of the line PQ

remember that

m1*m2=-1

we have

m1=7/3 ----> slope line AB

so

substitute and solve for m2

(7/3)*m2=-1

m2=-3/7

Step 3

Find the equation of the line PQ

The equation of the line into point-slope form is equal to

y-y1=m(x-x1)

we have

m=-3/7

P(7,6)

substitute

y-6=(-3/7)(x-7)

y=(-3/7)x+3+6

y=(-3/7)x+9 -----> multiply by 7 both sides

7y=-3x+63

7y+3x=63 -----> divide by 2 both sides

1.5x+3.5y=31.5 -----> multiply by -1 both sides

-1.5x-3.5y=-31.5

its B -1.5x − 3.5y = -31.5
