Step-by-step explanation:
4x3=12
5x7=35
A very good estimate of 48% of 60 is 30, since 48% is almost half of a number, and 30 is half of 60. When you 60 * 0.48, the real answer is 28.8.
Answer:
114
Step-by-step explanation:
To find - Find the sum of all the two-digit numbers that divide 170 with a remainder of 5.
Proof -
The 2 digit number is 11
170 = 11(15) + 5
The two digit number is 15
170 = 15(11) + 5
The two digit number is 33
170 = 33(5) + 5
The two digit number is 55
170 = 55(3) + 5
∴ we get
The two digit numbers are
11, 15, 33, 55
Their sum is equals to
11 + 15 + 33 + 55 = 114
Answer:
<h2><u><em>
8.17</em></u></h2>
Step-by-step explanation:
- <em>What is the number between 8.1 and 8.24?</em>
<em></em>
<em>Add the numbers and divide by 2 and you will find the average</em>
(8.1 + 8.24) : 2 =
8.17
8.17 is exactly half way between them.
Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
Hope I helped :)
