Sammy can roll a bowling ball at a rate of 5 miles in 30 seconds. How fast can he
IgorLugansk [536]

Answer:

600 mph

Step-by-step explanation:

Given that,

Distance covered by ball, d = 5 miles

Time taken, t = 30 seconds

1 second = (1/3600) hour

Speed = distance/time

v=\dfrac{5\ \text{miles}}{30\times \dfrac{1}{3600}\ \text{hour}}\\\\v=600\ mph

So, the speed of the ball is 600 mph.

Mnenie [13.5K]

Answer:The simple interest rate is 7.50%

Step-by-step explanation:

Simple interest, I =( P × T × R) / 100

Where P= Principal investment

T = Time in years

R = rate

Given

P= 981.60

I = 1000 - 981.60 = 18 .40

T = 13 weeks = 13 / 52 = 0.25 year

I =( P × T × R) / 100

Cross multiply

I × 100 = P × T × R

18.40 × 100 = 981.60 × 0.25 × R

1840 = 245.4 R

R= 1840 / 245.4

R = 7.498%

To the nearest tenth

R = 7.50%

Sholpan [36]

The simplified mathematical expressions with the first factor to the nearest tenth are:

7.8 x 10

3.3 x 10^{3}

2.1 x 10^{-3}

3.7

<h3>What are the simplified mathematical expressions ?</h3>

Scientific notation is used to simplify large numbers in smaller numbers.  In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

(8.6 x 10^{7}) . (9.1 x 10^{-8})

= (8.6 x 9.1) x 10^{7 - 8}

= 78.26 x10^{-1}

= 7.8 x 10

(6.9 x 10^{5}) . (4.8 x 10^{-3})

= 33.12 x 10^{5 - 3}

3.3 x 10^{3}

(3.7 x 10^{2}) . (4.6 x 10^{-3}) ÷ (1.4 x 10^{-6}) . (5.7 x 10^{8})

= 1.7 x 10 ÷ 8 x10²

0.21 x 10^{-2}

2.1 x 10^{-3}

(3.1 x 10^{5}) . (5.3 x 10^{-9}) ÷ (7.3 x 10^{2}) . (6.1 x 10^{-7}) = 3.7
