Answer:

Perimeter you add up all the sides.  If it is a horizontal or vertical line, you just write those values for the side lengths.  For the slanted one, I would use pythagorean theorem to solve it.

Step-by-step explanation:

If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12.  Find the square root of the sum of a squared plus b squared.  That will tell you C.  Then add C to the other 3 sides and that will give you the perimeter.

Answer:

Step-by-step explanation:

let the no of girls be x

ratio of boys to girls=4:7

4/7=16/x

do cross multiplication

7*16=x*4

112=4x

112/4=x

28=x

therefore there are 28 no of girls.

f + 6 = ?

Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.

For example, if f was 5, this is what the equation would look like:

5 + 6 = 11

If f was -3, this is what the equation would look like:

-3 + 6 = 3

So, again, the answer can be anything. It depends on what f is.

Answer:

72 pints of the first type

18 pints of the second type

Step-by-step explanation:

See attachment for complete question

Given

[tex]x \to[/tex] first type

[tex]y \to[/tex] second type

Final volume = 90; So:

[tex]x + y = 90[/tex]

From the question, we understand that:

70% of x and 95% of y gives 75% of the fruit juice

This is represented as:

[tex]70\% * x + 95\% * y = 75\%* 90[/tex]

Make x the subject in [tex]x + y = 90[/tex]

[tex]x = 90 - y[/tex]

Substitute: [tex]x = 90 - y[/tex] in [tex]70\% * x + 95\% * y = 75\% * 90[/tex]

[tex]70\% * (90 - y) + 95\% * y = 75\% *90[/tex]

Express percentage as decimal

[tex]0.70 * (90 - y) + 0.95 * y = 0.75 * 90[/tex]

Open brackets

[tex]63 - 0.70y + 0.95y = 67.5[/tex]

Collect like terms

[tex]- 0.70y + 0.95y = 67.5 - 63[/tex]

[tex]0.25y = 4.5[/tex]

Divide both sides by 0.25

[tex]y = \frac{4.5}{0.25}[/tex]

[tex]y = 18[/tex]

Recall that: [tex]x = 90 - y[/tex]

[tex]x = 90 - 18[/tex]

[tex]x = 72[/tex]

Answer:

A. 360 degrees

B. 360 degrees all the way around but each individual one is 90 degress

Step-by-step explanation:

Answer:

Step-by-step explanation:

B: the kite's diagonals intersect each other at a 90o degree angle.

A: It should come to 360. Let's if that happens.

Take the top angle (88) first. Notice that if you draw in both diagonals,  the will form Isosceles triangles. Let's deal with the shorter diagonal first.

The two angles at the base of the shorter diagonal are equal. That's because the sides opposite them are equal.

2x +88 = 180       Subtract 88 from both sides.

2x  = 92               Divide by 2

x = 46

Now lets look at the long narrow legs of the bottom isosceles triangle.

2x + 50 = 180      Subtract 50 from both sides

2x = 130               divide by 2

x = 130 /2

x = 65

Now add up all the angles that make up the interior of the kite.

Total = 46 + 46 + 65 + 65 + 50 + 88

Total = 360 just as it should.

Hi there!

I believe your answer is:

Here’s why:

⸻⸻⸻⸻

[tex]\boxed{\text{Calculating the Answer...}}}\\\\kx+12=3kx\\------------\\\rightarrow kx+12 - 12 = 3kx-12\\\\\rightarrow kx = 3kx - 12\\\\\rightarrow kx - 3kx = 3kx - 3kx - 12\\\\\rightarrow -2kx = -12\\\\\rightarrow \frac{-2kx = -12}{-2k}\\\\\rightarrow \boxed{x=\frac{6}{k}; k\neq 0}[/tex]

»»————-　★　————-««  

Hope this helps you. I apologize if it’s incorrect.  

Answer:

x = 6/k

Step-by-step explanation:

kx + 12 = 3*kx

to make like terms on same side shift kx to right hand side . when u shift positive kx to other side it becomes negative

12 = 3kx - kx

12 = 2kx

shift 2 to left hand side when u shift multilication changes to division.

12/2 = kx

6 = kx

to find x u must shift k to other side . here also same since k and x are multilied when k shifts to others side it becomes divisor.

6/k = x

Answer:

Step-by-step explanation:

angle 2 and angle 3 are linear pair

angle 1 and angle 7 are alternate exterior angle

angle 4 + angle 7=a80 degree

124 + angle 7=180

angle 7=180-124

angle 7=56 degree

angle 1 is supplementary to angle 2 ,angle 4, angle 6, angle 8 .In supplementary angle sum of two angle is always 180 degree.

angle 4 and angle 5 are supplementary angles because their sum is equal to 180 degree.

angle 4 + angle 5(being co interior angle)

3x+17+x+23=180

4x+40=180

4x=19=180-40

x=140/4

Answer:

A = 6x² + 97x + 391

Step-by-step explanation:

Given that,

The length of the shop, l = (3x+23)

The width of the shop, b = (2x+17)

The expression for the area of the shop is given by :

A = lb

Put all the values,

A = (3x+23) × (2x+17)

= 6x² +51x+46x +391

= 6x² + 97x + 391

Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.

Answer:

65+11x-17 =180

11x+48 =180

11x. =180-48

11x. =132

x =12

The complete steps for the value of x are;

1. 65 + (11x - 17) = 180

2. 11x + 48 = 180

3. 11x = 132

4. x = 12

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

In the figure,

Angles 65 degree and (11x - 17) degree are supplement to each other.

Now, We use the definition of supplementary angles, for find the value of x as;

Angles 65 and (11x - 17) degree are supplement to each other.

⇒ 65 + (11x - 17) = 180

Combine like terms, we get;

⇒ 11x + (65 - 17) = 180

⇒ 11x + 48 = 180

Subtract 48 both side, we get;

⇒ 11x + 48 - 48 = 180 - 48

⇒ 11x = 132

Divide by 11, we get;

⇒ x = 12

Thus, The value of x = 12

Therefore, The complete steps for the value of x are;

1. 65 + (11x - 17) = 180

2. 11x + 48 = 180

3. 11x = 132

4. x = 12

Answer:

Cos(15) = Cos(45-30)

Sin(15) = Sin(45-30)

Cos(45-30) - Sin(45-30)

Simplifying both brackets

Recall

Cos(A+B) = CosACosB - SinASinB (For cosine... The sign is always the opposite during expansion. If you look... Cos(A+B) became negative during its expansion;So if It was Cos(A–B)... Its expansion is CosACosB + SinASinB)]

Sin(A+B) = SinACosB + CosASinB

Now let's go!

Cos(45-30) = Cos45Cos30 + Sin45Sin30

From Trig

Cos45 = 1/√2

Cos30 = √3/2

Sin45 = 1/√2

Sin30 = 1/2

Substituting

Cos(45-30) = (1/√2).(√3/2) + (1/√2).(1/2)

= √3/(2√2) + 1/(2√2)

= 1 + √3/(2√2).

For

Sin(45 - 30)

= Sin45cos30 – Cos45Sin30

= (1/√2).(√3/2) – (1/√2).(1/2)

= √3/(2√2) – 1/2√2

= √3 – 1/(2√2)

So the question was

Cos15 - Sin15

Substituting...

1 + √3 / 2√2 – (√3 - 1)/ 2√2

When the Minus interacts with the parenthesis

We have

1 + √3 - √3 + 1 / (2√2)

= 2/2√2

= 1/√2.

THE ANSWER IS 1/√2 AND NOT 1/2.

YOU CAN VERIFY THIS WITH YOUR CALCULATOR ALSO.

YOU'LL HAVE 0.7071 WHICH IS SAME AS 1/√2.

Answer:

128degrees

Step-by-step explanation:

Using the theorem that states that the angle at the centre is twice the angle at the circumference, hence;

<D = 180 - 116

<D = 64

<x = 2(<D)

<x = 2(64)

<x = 128

Hence the measure of <x is 128degrees

Answer:

x= 113

y= 67

z= 49

Step-by-step explanation:

a triangle equals to 180° so lets start with the triangle that has two given degrees

28 + 39 + x = 180 solve

x = 113

no we can find y by using x + y = 180 since it's a straight line

we know the value of x so 113 + y = 180. solve.

y= 67

now do the same thing we did from the start since we have two given degrees on the other triangle.

67 + 64 + z = 180

z= 49
