True because you can multiply a number to get 40 such as 8 which means 5 was helped to get 40. So that is why 5 is a multiple

Answer:

False

Explanation:

A multiple of 40 would be something that 40 could multiply into. For example:

40 x 2 = 80

40 x 8 = 320

80 and 320 are multiples of 40.

Instead, 5 is a factor of 40. A factor of 40 can be multiplied by another number to make 40. For example:

2 x 20 = 40

5 x 8 = 40

2 and 5 are factors of 40.

SpyIntel [72]

Alright, so Ron parked his car for 8 hours at $3 per hour.

Harry parked his car for 7 hours at $3 per hour.

So, per day Ron is spending (8 * 3) = $24 a day
and Harry is spending ( 7 * 3 ) = $21 a day

So now solve for 5 days. 24 * 5 = $120 21 * 5 = $105

Add both together

Dmitriy789 [7]

Answer:

70 degrees

Step-by-step explanation:

$cos^{-1} \frac{3.4}{10}=x$

This implies that: $cos x= \frac{3.4}{10}$ Recall: $cos x=\frac{adjacent}{hypotenuse}$

From the diagram

Angle CAB, $x=cos^{-1} \frac{3.4}{10}=70.1 degrees$ =70 (to the nearest degree)

The value of the 9 is ten times the value of the 9 in 329,513. The value of the 2 is one-tenth the value of the 2 in 7,562. The

nexus9112 [7]

Answer: The number is 90,000.26

Step-by-step explanation:

Extracting key information from the question:-

*** The value of the "9" in Lea's riddle is 10 times the one in 329,513

*** The value of the "2" in the riddle is 1/10 the value of the 2 in 7,562.

*** The value of the 6 in the riddle is one-tenth the value of the 6 in 4.68

*** We are required to solve this possible and reveal the number.

Now, in the number 329,513 the place value of 9 is 9,000. According to the information provided, the value of the 9 in the riddle is ten times the value of the 9 in 329,513.

So, multiplying 9000 by 10 gives:-

9,000 × 10

= 90,000

Again, the value of the 2 in the riddle is one-tenth (1/10) the value of the 2 in 7,562. The value of 2 in 7,562 is 2 units, therefore one-tenth of this 2 units will give:-

1/10 × 2

= 0.2

Similarly, the value of 6 in the puzzle is one-tenth (1/10) the value of the 6 in 4.68; The 6 here is 6 hundredth = 0.6

Therefore, the value of 6 in the puzzle is:

1/10 × 0.6

= 0.06

In order to discover the number in Lea's riddle, we will then add up the calculated values:-

= 90,000 + 0.2 + 0.006

= 90,000.26

This number is the answer to Lea's riddle.
