A) It is located -25 and is to the right of Point A on the number line.

B) It is located at -15 and is to the right of Point A on the number line.

C) It is located at -25 and is to the left of Point A on the number line.

D) It is located at -15 and is to the left of Point A on the number line.

Answers

Answer:

A() it is located _25 and is the right of point A on the number line

Answer:

The Answer is C

Step-by-step explanation:

so if u draw out a number line, point A will be on the left side of the number line or in this case "0". So it is saying "point b is 5 less than point A" so since Point A is "-20" and it says "5 less than point A" so it would be adding up 5 more to -20 so it would be -25. But if it was 5 more than point A it would have been -15. If u take an example of money, like if u owe someone $20, it would be -$20 in your balance, and if he or she says u need to owe me 5 more $'s cuz there was damage now in your balance it would be -25.

x = 3    or x = -7

Step-by-step explanation:

(x + 2)^2=25

Take the square root of each side

sqrt((x + 2)^2)=sqrt(25)

x+2 = ± 5

Subtract 2 from each side

x+2-2 = -2 ±5

x = -2 +5  or x = -2 -5

Ravi's mass is 31 kg. His brother, Rajar, is 10 kg heavier than Ravi.
Find the ratio of Rajar's mass to their total mass.​

Answers

Answer:

31 : 41

Step-by-step explanation:

Given that Ravi's mass is 31kg . And his brother is 10 kg heavier than him . So his weight will be 31kg + 10kg = 41kg. So we have ,

[tex]\begin{cases}Mass \ of \ Ravi = 31kg \\ Mass of Brother \ = \ 41kg \end{cases}[/tex]

Therefore their total mass = 31 + 41 = 72 kg .

Therefore the ratio will be 41:72 .

The ratio of Rajar's mass to their total mass is 41:72.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, Ravi's mass is 31 kg.

His brother, Rajar, is 10 kg heavier than Ravi.

Weight of Rajar is 31+10=41 kg

Total weight =31+41

= 72 kg

The ratio of weights = 41:72

Therefore, the ratio of Rajar's mass to their total mass is 41:72.

The product of all digits of positive integer M is 105. How many such Ms are there with distinct digits?

Answers

Answer:

6

Step-by-step explanation:

105 is a composite number (not prime).  If you decompose 105 into its prime factors (see attached image), you get 105 = 3 x 5 x 7.  This means that the product 105 can only be written this way; any other way, for example 15 x 7 would not use numbers that are single digits.

The question boils down to how many ways the digits 3, 5, 7 can be arranged, using each digit exactly once.

That's a permutation problem, and it can be answered easily by thinking this way:  given the digits 3, 5, 7, there are 3 choices for the first digit, then 2 for the second digit (for EACH of the first choices), then only 1 choice for the final digit.

3 x 2 x 1 = 6 ways that 3, 5, 7 can be arranged to make a 3-digit number.  Here they are:

357, 375, 537, 573, 735, 753
