A car travels for 10 minutes

Mathematics
1 answer:
Marta_Voda [28]3 years ago
6 0

Answer:

40 km/h

Step-by-step explanation:

s = ut where s - Distance

u - Speed

t - Time

when t = 10 min

= 10/60 hours

S1 = 30 * 10/60

= 5km

when t= 20 min

= 20/60 hours

S2 = 45 *20/60

= 15 km

Then total distance = S1 + S2

= 5 + 15

= 20 km

Total time period = (10 + 20 ) / 60 hours

= 1/2 hours

Then average speed = U

S = UT

U = S/ T

= 20/ 0.5 km/ h

= 40 km/ h

What is the value of (f+g)(5)if f(x)=7x-2 and g(x)=9x-4?
Arada [10]

Answer:

74

Step-by-step explanation:

All you have to do it first add f(x)+ g(x) and then plug in x=5.

(f+g) = f(x) + g(x)

= (7x- 2) + (9x-4)

= 7x - 2 + 9x - 4

= 16x - 6

(f + g)(5) = 16(5) - 6

= 80 - 6

= 74

Liula [17]

Answer:

1. d 2. d 3. a

Step-by-step explanation:

1. factor

((w-4)(w-6))/((w-5)(w-6))+8/(w-5)

solve

(w-4)/(w-5)+8/(w-5)

(w+4)/(w-5), so d

2.factor

((b+2)(b-4))((b+2)(b-1))-6/(b-1)

solve

(b-4)/(b-1)-6(b-1)

(b-10)/(b-1), so d

3. (2/5t-3/3t)/(1/2t+1/2t)

(2/5t-1/t)/(2/2t)

(2/5t-1/t)/(1/t)

t(2/5t-1/t)

2/5-1=-3/5, so a

The scale factor is what u multiply the first image by to get the second image. So by dividing the second image by the first image will give u the scale factor.

6 / 1.5 = 4....so there is a scale factor of 4 because 1.5 * 4 = 6
