A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?

Arturiano [62]

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2 $\pi$ r

Thus,

Circumference of the track = 2 x $\frac{22}{7}$ x 1.5

= 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

= 330 miles

The total distance traveled by the car is 330 miles.

Solve the following system of equations algebraic<br> y=x^2+3x-29<br> y=2x-9

Lady bird [3.3K]

Step-by-step explanation:

Given equations:

y = x² + 3x - 29 ------ (i)

y = 2x - 9 ---------------- (ii)

Now to solve this problem, we must determine the value of x and y;

Equate equations 1 and 2;

x² + 3x - 29 = 2x - 9

x² + 3x - 2x - 29 + 9 = 0

x² + x - 20 = 0

x² + 5x - 4x - 20 = 0

x(x + 5 ) - 4(x + 5) = 0

(x - 4) (x+ 5) = 0

x - 4 = 0 or x + 5 = 0

x = 4 or x = -5;

So; solve for y now;

y = 2x - 9

input x = 4 or x = -5;

y = 2(4) - 9 or y = 2(-5) - 9

y = -1 or y = -19

Can someone please answer this question please answer it correctly please show work

Zina [86]

Answer:

34) A

35) C

36) D

Step-by-step explanation:

34) The perimeter of a triangle is equal to the sum of the lengths of its sides

Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)

Combine like terms (same variables)

(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)

9.6p + 0.4q + 2.2r

Time possibilities

1 hour - $3 - $5 = $-2 No

2 hours - $6 - $5 = $1 Yes

3 hours - $9 - $5 = $4 Yes

4 hours - $12 - $5 = $7 Yes

5 hours - $15 - $5 = $10 Yes

6 hours - $18 - $5 = $13 Yes

7 hours - $21 - $5 = $16 Yes

8 hours - $24 - $5 = $19 No

9 hours - $27 - $5 = $22 No

The possible hours that Ms. Barnes can park are 2 - 7 hours

The only inequality graph that represents all of these values is C

Convert to improper fractions

Divide by finding the reciprocal

Convert back to a mixed number

$-1\frac{7}{9}$

Hope this helps :)
