It takes Priti 4 hours to drive from Ashdown to Bridgeton at an average speed of 50 mph. She then drives 30 miles from Bridgeton

Sveta_85 [38]

Answer:

Her average speed from Ashdown to Carton is approximately 48.4 mph

Step-by-step explanation:

The time and speed of the motion of Priti are as follows;

The time it takes Priti to drive from Ashdown to Bridgeton, t₁ = 4 hours

The average speed she drove from Ashdown to Bridgeton = 50 mph

The distance she drove from Bridgeton to Carton, d₂ = 30 miles

Her average speed from Bridgeton to Carton = 40 mph

The distance from Ashdown to Bridgeton, d₁ = 50 mph × 4 hours = 200 miles

The time it takes Priti to drive from Bridgeton to Carton, t₂ = 30 miles/(40 mph) = 0.75 hour

Average velocity, $v_{ave}$ = (Total distance traveled, Δd)/(Total time, Δt)

Δd = d₁ + d₂, Δt = t₁ + t₂

Δd = 200 miles + 30 miles = 230 miles

Δt = 4 hours + 0.75 hour = 4.75 hours

∴ The average velocity, $v_{ave}$ = (230 miles)/(4.75 hours)

∴ $v_{ave}$ = (920/19) mph

Her average speed from Ashdown to Carton, rouded to 1 d,p, $v_{ave}$ ≈ 48.4 mph

adelina 88 [10]

8 employees exercise at least three times a week

<em><u>Solution:</u></em>

At the office where Mika works 41% of the 19 employees exercise at least three times a week

To find: Number of people who exercise at least three times a week

From given information,

Total employees = 19

Employees exercise at least three times a week = 41 % of total employees

Therefore, we have to evaluate 41 % of 19

Number of people exercise at least three times week = 41 % of 19

$\rightarrow 41 \% \text{ of } 19 = 41 \% \times 19\\\\\rightarrow 41 \% \times 19 = \frac{41}{100} \times 19 = 0.41 \times 19\\\\\rightarrow 41 \% \times 19 = 0.41 \times 19 = 7.79 \approx 8$

Thus approximately 8 employees exercise at least three times a week

How to solve this?

nevsk [136]

Answer:

Answer of 17 is ㏒( $x^{2}$ +15x), Answer of 33 is x = 8 , Answer of 35 is x = ㏒10/㏒2 , Answer of 37 is x = -㏒12/㏒8 and Answer of 39 is x = 5

Step-by-step explanation:

17. ㏒x + ㏒(x+15)

Using property ㏒a + ㏒b = ㏒a×b

∴ ㏒x + ㏒(x+15)

㏒x×(x+15)

㏒( $x^{2}$ +15x)

The answer is ㏒( $x^{2}$ +15x)

33. 2^(x-5) = 8

2^(x-5) = 2^3

Using property 2^a = 2^b

Then a = b

∴x-5 = 3

x = 8

The answer is x = 8

35. 2^x = 10

Taking log on both sides gives

㏒2^x = ㏒10

x×㏒2 = ㏒10

x = ㏒10/㏒2

The answer is x = ㏒10/㏒2

37. 8^-x = 12

Taking log on both sides gives

㏒8^-x = ㏒12

-x×㏒8 = ㏒12

x = -㏒12/㏒8

The answer is x = -㏒12/㏒8

39. 5(2^3 × x) = 8

5(8×x) = 8

x = 5

The answer is x=5
