equilateral triangle has all sides So,
perimeter = a+b+c= 12+12+12=36
Equilateral triangles are the same length on every side, since the size of 1 side was given (12) you multiply by 3 (number of sides)
12•3=36

solve the equation - 11 + 29 = - 2x + 4
Answers
Answer:
x = -7
Step-by-step explanation:
-11+29=-2x+4
18=-2x+4
-4 -4
14=-2x
-2 -2
-7=x
Solution:-
-11 + 29 = -2x + 4
18 = -2x + 4
18 - 4 = -2x
14 = -2x
14/-2 = x
-7 = x
Max makes three piles of cards, each consisting of only a Queen and a Jack. Lisa draws one card from each pile. What is the probability that Lisa draws two Queen and a Jack in any order? Make a tree diagram of all the choices
Answers
Answer:
3/8
Step-by-step explanation:
The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).
There are only 3 ways in which Lisa can draw two Queens and a Jack:
Queen, Queen, Jack
Queen, Jack, Queen
Jack, Queen, Queen
The probability of each one happening is 1/8
This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:
1/2 x 1/2 x 1/2 = 1/8
This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8
It can be represented on a tree diagram however I am not sure how I can show images/drawings on this

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:
18×8=
Now all we have to do is multiply:

Jinny is selling bracelets for $2.50. So far, she has earned $175.00. She needs to earn more than $230.00 in order to meet her goal.
How many more bracelets, x, does she need to sell in order to reach her goal? Select the inequality that includes the fewest number of bracelets that she can sell and still reach her goal.
Answers
Answer: 25
Step-by-step explanation:
she’s earned 175 so far she needs 230. So 230-175=55, so she needs 55 more dollars. 55÷2. 50(price of each bracelet) = 25
She/they earned one hundred seventy fife dollars (175$)
She needs 230 55 ÷2 = 25

Find the number that makes the ratio equivalent to 1:5.
6:
Answers
1:5 is the same as 1/5.
So, the question really is 1/5 = 6/what?
6/30 is the same as 1/5
So the missing number is 30.
Answer:
box = 30
Step-by-step explanation:
You could set this up very formally as a proportion. It would look like this.
1/5 = 6/x
Now all you have to do is cross multiiply.
1*x = 5 * 6
x = 30
So the answer that goes in the box is 30
Or you could just say to yourself. "The 1 was multiplied by 6. What do I have to multiply the 5 by to keep the ratio the same?"
The answer is 6
6 * 5 = 30
In higher math you are going to want to use the first method.

6(9 + 5x) = 54 +
Answers
Hi
to progress in math, you must : know by heart the rules and formulas then train.
rule : a ( b+c ) = a*b + a*c.
this propertie is call distributivity .
so we have : 6 ( 9+5X)
here : a = 6
b = 9
c = 5X
so 6 ( 9+5X) = ?
I let you have a shot. Ask in comments section if you are stuck. But try first !
Answer:
1) rearrange terms:
6(9 + 5x) = 54
6(5x + 9) = 54
2) Distribution :
6(5x + 9) = 54
30x + 54= 54
3) subtract 54 from both side:
30x + 54 = 54
30x + 54 - 54 = 54 - 54
4) Simplify: subtract the numbers
30x = 0
5) Divide both side of the equation by the same term:
30x = 0
30x√30 = 0√30
6) Simplify: cancel term that are in the both numerator and denominator
x = O√30
solution :
x = 0]

If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)
Answers
Answer:
4 hectaresStep-by-step explanation:
The scale factor is:
k = 1/400Applied to the area we consider k² as the area is the product of two dimensions.
Find the actual area:
0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectaresThe height of a bookcase is 1.93 meters. Which expression converts this height to feet? Note: 1 foot is approximately 0.3048 meters and 1 meter is approximately 3.2808 feet.
A
1.93m×(0.3048ft1m)
B
1.93m×(3.2808ft1m)
C
1.93m×(1m0.3048ft)
D
1.93m×(1m3.2808ft)
Answers
The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)
To make the conversion of meters to feets , we use dimensional analysis ;
We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :
Recall :
1 meter = 3.2808 feets
Then the height of the bookcase in feets will be :
1.93 meters × 3.2808ft / 1m
Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m
