Answer:
140 toy cars
Step-by-step explanation:
The ratio of Ed's toy car to Pete's toy car is initially given as 5:2
Ed gave Pete a total number of 30 cars
Let x represent the greatest common factor that exists between both number
Number of Ed's car is represented as 5x
Number of Pete car is represented as 2x
Since they each have an equal number of cars which is 30 then we can solve for x as follows
5x-30=2x+30
Collect the like terms
5x-2x= 30+30
3x= 60
Divide both sides by the coefficient of x which is 3
3x/3=60/3
x=20
Ed's car is 5x, we substitute 20 for x
5(20)
= 100 cars
Pete car is 2x,we substitute 20 for x
2(20)
= 40 cars
Therefore, the total number of cars can be calculated as follows
= 100+40
= 140 toy cars
Hence they have 140 toy cars altogether
Answer:
45.1
Step-by-step explanation:
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
Answer:
-56
Step-by-step explanation:
Formula to get determinant is::
![\left[\begin{array}{ccc}a&b\\c&d\end{array}\right] = ad-bc](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5Cend%7Barray%7D%5Cright%5D%20%3D%20ad-bc)
0(0)-8(7)
0 - 56
-56
Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.
<h3>How to round numbers?</h3>
The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.
Now, let's round the distance covered by Marisol each day:
- Monday: 12.3 = 12
- Tuesday: 14.1 = 14
- Wednesday: 17.7= 18
- Thursday: 11.8 = 12
- Friday: 15.2 = 15
<h3>What distance did Marisol covered?</h3>
To know this just add the distance every day:
- 12 + 14 +18 + 12 + 15 = 71 miles
<h3>How much more did she bike on Wednesday than on Thursday?</h3>
Distance covered on Wednesday - distance covered on Thursday
Note: This question is incomplete; here is the missing information:
- Monday 12.3
- Tuesday 14.1
- Wednesday 17.7
- Thursday 11.8
- Friday 15.2
