Answer:
(9 1/2) * (19 1/4) = 1463/8 = 182 7/8
Step-by-step explanation:
Conversion a mixed number 9 1/2
to a improper fraction: 9 1/2 = 9 1/2
= 9 · 2 + 1/2
= 18 + 1/2
= 19/2
To find a new numerator:
a) Multiply the whole number 9 by the denominator 2. Whole number 9 equally 9 * 2/2
= 18/2
b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19
c) Write a previous answer (new numerator 19) over the denominator 2.
Nine and one half is nineteen halves
Conversion a mixed number 19 1/4
to a improper fraction: 19 1/4 = 19 1/4
= 19 · 4 + 1/4
= 76 + 1/4
= 77/4
To find new numerator:
a) Multiply the whole number 19 by the denominator 4. Whole number 19 equally 19 * 4/4
= 76/4
b) Add the answer from previous step 76 to the numerator 1. New numerator is 76 + 1 = 77
c) Write a previous answer (new numerator 77) over the denominator 4.
Nineteen and one quarter is seventy-seven quarters
Multiple: 19/2
* 77/4
= 19 · 77/2.4
= 1463/8
Answer:
18 km/hr
90 km
Step-by-step explanation:
We know that there are
1000 m = 1 km
and
3600 s = 1 hr
We need to convert m/s to km/h
5 m 3600s 1 km 18000km 18 km
------ * ------------ * ------------ = --------------- = ------------
s 1 hr 1000m 1000 hr hr
It is 18 km/hr since the units cancel.
We want to know how far the cyclist travels
d=rt
We know the rate 18km/hr and the time = 5 hr
d = 18 km/hr * 5 hr
d =90 km
So P(-0.7537 < z < 1.3190) = 0.9063 - 0.2254 = 0.6809
The answer would be (D) because we know that Tim works out for 35 minutes a day and that if he keeps this constant pace for 4 days then you would end up with the expression: 4 x (25 + 10). Hope this answers your question!
