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

Answer:

She would need to make 5 consecutive free successful throws

Step-by-step explanation:

Equations

A basketball player wants to improve his percent of successful throws to 85%.

She currently has made 12 out of 15 free throws, which gives a success percentage of 12/15*100=80%

So, she needs a number of free consecutive free throws to increase that number to the desired target.

The percentage of success can be calculated as:

[tex]\displaystyle P=\frac{\text{successful throws}}{\text{total throws}}*100[/tex]

Let's assume x is the number of required consecutive successful throws. Since she has already thrown 15 times, out of which has had 12 successful throws, now she will have 15+x total throws and 12+x successes, thus the new percentage is:

[tex]\displaystyle P=\frac{12+x}{15+x}*100[/tex]

And this percentage must be equal to 85%, thus:

[tex]\displaystyle \frac{12+x}{15+x}*100=85[/tex]

a) The equation to represent the situation is:

[tex]\mathbf{\displaystyle \frac{12+x}{15+x}*100=85}[/tex]

b) Let's solve it.

Multiply by 15+x:

[tex]\displaystyle (12+x)*100=85(15+x)[/tex]

Dividing by 5:

[tex]\displaystyle (12+x)*20=17(15+x)[/tex]

Operating:

[tex]\displaystyle 240+20x=255+17x[/tex]

Subtracting 17x and 240:

[tex]\displaystyle 20x-17x=255-240[/tex]

Simplifying:

[tex]\displaystyle 3x=15[/tex]

Dividing by 3:

x = 5

She would need to make 5 consecutive free successful throws

The number of throws is an illustration of proportions.

The number of free throws to raise her percent to 85% is 5

(a) The equation

The proportion is given as: 12 out of 15.

Let the number of throws be n.

So, the proportion would be:

[tex]\mathbf{Proportion = \frac{12 + n}{15 + n}}[/tex]

To make 85% success, then the proportion must equal 85%.

So, we have:

[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]

(b) The solution to the equation

In (a), we have:

[tex]\mathbf{\frac{12 + n}{15 + n} = 85\%}[/tex]

Express 85% as decimal

[tex]\mathbf{\frac{12 + n}{15 + n} = 0.85}[/tex]

Cross multiply

[tex]\mathbf{12 + n = 0.85(15 + n)}[/tex]

[tex]\mathbf{12 + n = 12.75 + 0.85n}[/tex]

Collect like terms

[tex]\mathbf{n -0.85n= 12.75 -12 }[/tex]

[tex]\mathbf{0.15n= 0.75}[/tex]

Divide both sides by 0.15

[tex]\mathbf{n= 5}[/tex]

Hence, the number of free throws to raise her percent to 85% is 5

Answer:

-12x - 2 < -62

-12x - 2 > 34

Step-by-step explanation:

1. Start with

x > 5

Multiply both sides by -12.

-12x < -60

Subtract 2 from both sides.

-12x - 2 < -62

2. Start with

x < -3

Multiply both sides by -12.

-12x > 36

Subtract 2 from both sides.

-12x - 2 > 34

Answer:

-12x - 2 < -62

-12x - 2 > 34

Answer:

1) 4

2) 45

3) 104

Step-by-step explanation:

1)

let x be your number.

((6x+8)/4)-5 = 3

add 5

(6x+8)/4=8

multiply by 4 to get rid of the denominator

6x+8=32

subtract 8

6x=24

divide by 6

x=4

2) Same type. (this time I won't explain every step)

let x be your number

((x/9)-8+6)*7 =21

(x/9)-8+6=3

(x/9)-2=3

x/9 = 5

x=45

3) Same type... Again

let x be your number

(((x-4+11)*2)/6)-8 = 29

((x-4+11)*2)/6=37

(x-4+11)*2 = 222

x+7=111

x= 104

You take the distance that he has to travel (114m) and you divide it by the distance you're given that he is moving at every time (6m). this gives us 19. Then you take that and multiply it by how many seconds it takes him to move the given 6m (4s), which gives us an answer of 76 seconds

Answer:

s+h=40 and 18s+14h=700

Step-by-step explanation:

lets say  

s= number of scarves sold  

and  

h=number of hats sold  

since the total of hats/scarves equals 40 then that means that scarves+hats sold equals 40 so  

s+h=40  

the second constraint it found similarly,

scarves and hats are being sold for 18$ and 14$ respectively and together they need to equal 700$ so you plug it into a similar equal as before  

18s+14h=700

To find the slope of the line, you want to use formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Since we are given two points, we can directly plug them in and solve.

[tex]m=\frac{-21-(-10)}{4-3} =\frac{-11}{1} =-11[/tex]

Now, we know that the slope is -11.

Answer:

BD = 15 m

Step-by-step explanation:

Mathematically, we can find the perimeter of a triangle by adding all of the sides

Mathematically, the line from the top vertix of an isosceles triangle is perpendicular to the base line

So what this mean is that it splits the base line into 2 equal parts

So, in this case, since AC is base;

AD = CD

Please check the attachment for diagrammatic representation

So from the diagram;

25-x + x + BD = 40

25 + BD = 40

BD = 40-25

BD = 15 m
