Answer:
x = 6 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 12 and h = 4, then
A = [tex]\frac{1}{2}[/tex] × 12 × 4 = 6 × 4 = 24 cm²
Then area of parallelogram = 3 × 24 = 72 cm²
The area (A) of a parallelogram is calculated as
A = bh ( b is the width and h the height )
Here b = x and h = 12, thus
12x = 72 ( divide both sides by 12 )
x = 6
The width of the parallelogram is 6 cm
Answer:
6=width
Step-by-step explanation:
Ok so when looking at the question it say that the area of the paraellagram is three times the area of the trianlgle.
-to find the area of a triangle you must use the equation A=1/2LxW would be 24
now once you have 24 you times it by 3 which is 72 (you do this because in the problem it says the paraellagram's area is three times the triangles area so 72 is the paraellagram's area.
now you divide 72 by the only other measurement given to you by the paraellagram which is 12 the length
after dividing the 2 you should get 6 which is the answer
you do this because by dividing 72 by 12 you get the other amount needed to make 72 which was the width
A=1/2(4)x12=24
24x3=7272/12=6

the perimeter of a rectangular pool is 326 M if the length of the pool is 87 M what is its width
Answers
Half the perimeter is equal to the length plus the width.
326 /2 = 163
Length + width = 163
87 + width = 163
Width = 163 - 87
Width = 76 meters
3(6d-24)=6(12+3d)
i need help
Answers
Answer:
No solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
3(6d−24)=6(12+3d)
Step 1: Simplify both sides of the equation.
3(6d−24)=6(12+3d)
(3)(6d)+(3)(−24)=(6)(12)+(6)(3d)(Distribute)
18d+−72=72+18d
18d−72=18d+72
Step 2: Subtract 18d from both sides.
18d−72−18d=18d+72−18d
−72=72
Step 3: Add 72 to both sides.
−72+72=72+72
0=144

Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p, made from selling n candy bars. p = 1.25n - 475 How many candy bars must be sold to make a profit of $950?
Answers
Answer:
380 candy barsStep-by-step explanation:
Step one:
we are told that the expression for profit is
[tex]p = 1.25n - 475[/tex]-----------------1
the above equation represents the situation
given
profit is $950
Required
n=number of bars
950=1.25n-475
collect like terms
950-475=1.25n
475=1.25n
divide both sides by 1.25
n=475/1.25
n= 380candy bars

Answer: 8. 3^4+n^4, 9. 7^3+m^4, and 10. s+2t^3.
Step-by-step explanation:
Answer:
8. 4n + 12
9. 6m + 28
10. 3s + 6t
Step-by-step explanation:
8. As can be seen in the image, there are four sides that are n long and four sides that are 3 long. This can represented like this:
4n + 3(4)
Simplify the expression:
4n + 12
9. In this figure, there are 3sides with the length 7 and 4 sides with the length m. However, the length of the top of the figure seems to be unknown. Its length is the same as the length of the bottom half of the figure, which is 2m and one 7. So, add two more m and one more 7 to our expression. Now our expression looks like this:
6m + 7(4)
Simplify:
6m + 28
10.There are 3 sides with length s + 2t. This can be represented like this:
3(s + 2t)
Multiply the 3 by both terms in the parentheses:
3 * s = 3s
3 * 2t = 6t
The simplified expression is:
3s + 6t

R(4,4). State your answer in
simplest radical form.
please help !
Answers
Answer:
Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]
Step-by-step explanation:
Given, A(-2, -1), B(10, -1), and R(4, 4).
Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]
Distance between A(-2, -1) and B(10, -1) using distance formula:
[tex] \overline{AB} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(10 -(-2))^2 + (-1 -(-1))^2} [/tex]
[tex] \overline{AB} = \sqrt{(12)^2 + (0)^2} [/tex]
[tex] \overline{AB} = \sqrt{(144 + 0)} [/tex]
[tex] \overline{AB} = \sqrt{144} = 12 [/tex]
Distance between B(10, -1) and R(4, 4):
[tex] \overline{BR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 - 10)^2 + (4 -(-1))^2} [/tex]
[tex] \overline{BR} = \sqrt{(-6)^2 + (5)^2} [/tex]
[tex] \overline{BR} = \sqrt{(36 + 25)} [/tex]
[tex] \overline{BR} = \sqrt{61} [/tex]
Distance between A(-2, -1) and R(4, 4):
[tex] \overline{AR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 -(-2))^2 + (4 -(-1))^2} [/tex]
[tex] \overline{AR} = \sqrt{(6)^2 + (5)^2} [/tex]
[tex] \overline{AR} = \sqrt{(36 + 25)} [/tex]
[tex] \overline{AR} = \sqrt{61} [/tex]
Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]
Perimeter of ∆ABR = [tex] 12 + \sqrt{61} + \sqrt{61} [/tex]
Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]
Refer to the spinner. Find the odds of the spinner not landing on an even number.
• 1:3
•1:1
•2:1
•1:2
Answers
Explanation:
We have three numbers that aren't even, and they are {1,3,5}
There are three numbers that are even, and they are {2,4,6}
The odds in favor of not getting an even number is 3:3 = 1:1
To list the odds in favor, you write the number of ways to get what you want, followed by a colon, then the number of ways to get what you don't want. In this case, both counts are 3. The ratio 3:3 reduces to 1:1 after dividing both parts by 3.
Answer:
1:1
Step-by-step explanation:
how many odd sections are even: 3
how many sections are not even: 3
the odds are 3 : 3= 1:1
odds are what you expect to come out versus what you don't expect(favorable to un favorable).
confusion comes in when talking about probability
probability is what you want to come out versus the total chances whether odd or even(favorable to total outcomes). eg
in this example
the probability of it not landing on the even number is:
number of odd sections= 3 = 1:2
number of total outcomes= 6
The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees
Answers
Answer:
Smallest angle = 40
Step-by-step explanation:
Angle sum property:Sum of all three angles of triangle is 180
2x - 6 + 3x + 5 + 2x + 20 = 180 {Combine like terms}
2x + 3x + 2x - 6 + 5 + 20 = 180
7x + 19 = 180 {Subtract 19 from both sides}
7x = 180 - 19
7x = 161 {Divide both sides by 7}
x = 161/7
x = 23
2x - 6 = 2*23 - 6 = 46 - 6 = 40
3x + 5 = 3*23 + 5 = 69 + 5 = 74
2x + 20 = 2*23 + 20 = 46 + 20 = 66
Smallest angle = 40
