Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
Given : 58% of 121.
To find : estimate 58% of 121 by using 10%.
Solution : We have given 58%
Estimate of 58% is 60%
We need to use 10%
We can write 60% as 6 times of 10%
Since , 10% of 121
= 12.1
60% = 6 times of 10%
Plugging the values
60% == 6 times of 12.1
6 *12.1 = 72 .6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Therefore, 58% of 121 by using 10% is 70.18.
Answer:
E. -5i/4
Step-by-step explanation:
The greatest common factor of 16 and 64 is 16.
Given that we need to find the greatest common factor of 16 and 64,
To find the greatest common factor (GCF) of two numbers, such as 16 and 64, we need to determine the largest number that divides both of them without leaving a remainder.
First, let's find the factors of each number:
Factors of 16: 1, 2, 4, 8, 16
Factors of 64: 1, 2, 4, 8, 16, 32, 64
As we can see, both numbers have the factors 1, 2, 4, 8, and 16. The largest number that divides both 16 and 64 without leaving a remainder is 16.
In general, when finding the GCF of two numbers, we look for the common factors they share and choose the largest one.
In this case, since 16 is the largest common factor, it becomes the GCF.
Hence the greatest common factor is 16.

A. 5 minutes
B. 4 minutes
C. 3 minutes
D. 13 minutes
Answer:
A. 5 minutes
Step-by-step explanation:
We can solve this question using proportions
Let x be the number of minutes needed to type 225 words.
8 minutes = 360 words
x = 225 words
Cross-multiply
360 × x = 225× 8
360 x = 1800
Divide both-side of the equation by 360
=
(On the left-hand side of the equation, 360 at the numerator will cancel-out 360 at the denominator, while on the right-hand side of the equation 1800 will be divided by 360)
x= 5 minutes
Therefore, it will take 5 minutes to type 225 words
Well, it cant be option B because then it wuld be half the time (180 mins.)
It cant be option D becasue then it would be over 360 mins, seeing that it only took 8 mins to type 360
And it cant be option C beacuse it would be too small, if 4 mins is to small then 3 mins is worse
Your answer would be A 5 minutes it's just a little bit above 4 mins(half)
