Answer:
Sharon spent a total of 49 minutes yesterday reading the book
Step-by-step explanation:
Step 1: Calculate the rate at which she reads
The total number of pages she reads at any given time interval can be expressed as;
T=P×m
where;
T=Total number of pages she reads
P=the rate at which she reads in number of pages per minute
m=total number of minutes she takes reading a book
In our case;
T=10 pages
P=p
m=35 minutes
replacing;
10=p×35
p=10/35
p=(10/35)
The rate at which she reads=(10/35) pages per minute
Step 2: Calculate the time she spent reading the book yesterday
Yesterdays variables are as follows;
T=14 pages
p=(10/35) pages per minute
m=unknown
replacing;
14=(10/35)×m
m=14×(35/10)
m=49

Answer: 115°
Step-by-step explanation:
We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:
(8x - 5) + (2x) + (3x - 10) = 180
8x - 5 + 2x + 3x - 10 = 180
Collect like terms
8x + 2x + 3x = 180 + 5 + 10
13x = 195
x = 195/13
x = 15
The angles are:
8x - 5 = 8(15) - 5 = 120 - 5 = 115°
2x = 2(15) = 30°
3x - 10 = 3(15) - 10 = 45 - 10 = 35°
Therefore, the largest angle is 115°
If you want to multiply a decimal by a whole number, just ignore the decimal point and multiply like normal! Then, bring the decimal point back for the answer. for example 2×0.2
first multiply 2*2=4
and then place the decimal we have one value after decimal so the answer is 0.4
Answer:
0.625
Step-by-step explanation:
Given :
Ambell company uses or procures batteries from two manufacturers.
The life of a battery in critical tool is at = 32 hours
Ambell uses 70% of its batteries from manufacturer 1 and out of that 90% batteries lasts for about 40 hours.
Similarly, 75% of the batteries procured from the manufacturer 2 lasts for about 40 hours.
Therefore, the probability that a battery is form manufacturer 1 is :
= 0.625
