Answer:
- the hypotenuse side, c = 23.1 cm
- angle A = 41.26 ⁰
- angle B = 48.74 ⁰
Step-by-step explanation:
Given;
first leg of the right triangle, a = 15.21 cm
second leg of the right triangle, b = 17.34 cm
Angle C = 90 ⁰
The missing parameters;
- the hypotenuse side = c
- angle A
- angle B
Use Pythagoras theorem to calculate the missing side "c", which is the hypotenuse
c² = a² + b²
c² = (15.21)² + (17.34)²
c² = 532.02
c = √532.02
c = 23.1 cm
The missing angle A is calculated as;
The missing angle is calculated as;
B = 90⁰ - A
B = 90⁰ - 41.26⁰
B = 48.74⁰

Answer:
Twelve less three times a number is at least nine.
Twelve minus the product of three and a number is no smaller than nine.
Step-by-step explanation:
complete question is:
Twelve less than three times a number is greater than or equal to nine.
Twelve less than three times a number is at least nine.
Twelve less three times a number is at least nine.
Twelve minus the product of three and a number is no more than nine.
Twelve minus the product of three and a number is no smaller than nine.
ANSWER:
Twelve less three times a number is at least nine.
The phrase "twelve less three..." means that the "three times a number" is being subtracted from twelve. So, it has to be at least nine.
Twelve minus the product of three and a number is no smaller than nine.
Even the least number you suppose is 1 we'll get 9
e.g: 12-3(1)=9. Therefore, this statement also represent the inequality
Check attachment for the remaining part of the questions.
Answer:
The correct options are:
C. Twelve less three times a number is at least nine.
F. Twelve minus the product of three and a number is no smaller that nine.
Step-by-step explanation:
Given 12 - 3x ≥ 9,
we want to check which phrase from the options can be used to represent the inequality.
12 - 3x: This means the product of 3 and a number is subtracted from 12.
≥: This is the "Greater or equal to" symbol. It is used to show that the quantity on the left hand side of the symbol is at least, the exact quantity on the right. It means the quantity on the right hand side can be equal, or greater, but can never be smaller the quantity on the left hand side.
So, the statement means
When 3 is multiplied my a number, and then the result is subtracted from 12, what we have is at least 9.
The only statements that corresponds to this from the options are:
1. Twelve less three times a number is at least nine.
2. Twelve minus the product of three and a number is no smaller that nine.

The three numbers are 6, 7 and 9
Explanation:
First of all exclude the numbers which aren't correct.
From the 4th data,We can conclude the digit 5, 2 and 3 are wrong.
Now,
- 147 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 964 - Two digits are correct but at wrong place
- 523 - All digits are wrong
- 286 - One digit is right but in the wrong place
We've to find the three digits :
From case 4: 5, 2 and 3 are wrong
So, remove 5, 2 and 3 from all the cases
The numbers are:
- 147 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 964 - Two digits are correct but at wrong place
- _86 - one digit is right but in the wrong place
From 1st and 3rd we can say that: 4 is present in both the case but wrongly placed.
Now the digits become:
- 1_7 - One digit is right but wrong placed
- 189 - One digit is right and placed correctly
- 96_ - Two digits are correct but at wrong place
- _86 - one digit is right but in the wrong place
From 3rd and 4th case we can say that: 9 and 6 are correct but wrongly placed, 8 is not the number and 6 is placed at first
So, the two numbers of a 3 digit number are 6 and 9
From 2nd, 3rd and 4th case, the position of 6 and 9 are:
6 _ 9
From 1st case, 7 is the digit but wrongly placed. So, the 3 digit number becomes:
6 7 9

Answer:
a system of equations , as below
Step-by-step explanation:
4y-x
2x-4
x+y
use any two of the above to find a formula for one of the variables since they are all equal to each other.. btw.. it makes it much easier .. that they are all equal. :)
2x-4=x+y ⇒ x-4=y use this to plug into the y in the top formula
4(x-4)-x=2x-4 ⇒ 4x-16-x=2x-4 ⇒ 3x-16=2x-4 ⇒ x=12 yay! ;) now plug in 12 for x
2(12)-4=(12)+y ⇒ 24-4 = 12 +y ⇒ 8=y yay ! now we have both x and y
x=12
y= 8
this checks by plugging in the two number found for x & y (btw I had to try this about 4 times ) :P I kept messing up the algebra which is soooo easy to mess up.
