Answer:

The four angles are;

30 degrees,  85 degrees, 95 degrees , and 150 degrees

Step-by-step explanation:

Call the four angles of this quadrilateral A, B, C, and X (being X the smallest angle)

Then angle A is 55 degrees larger than X , therefore we can write it as X+55

Angle B is 65 degrees larger than X , therefore we can write it as X+65

Angle C is 120 degrees larger than X , therefore we can write it as X+120

Then we know that the addition of all four angles of a quadrilateral must give 360 degrees , so we have:

X + X + 55 +X + 65 + X + 120 = 360

that is:

4 X + 240 = 360

4 X = 360 -240

4 X = 120

X = 120/4

X = 30 degrees

and the other angles are:

30 + 55 = 85 degrees

30 + 65 = 95 degrees

30 + 120 = 150 degrees

Answer:

Here is the solution solution-

(-15x+6y)-(-10x+7y)

= -15x+6y+10x-7y

= (-15x+10x)+(6y-7y)

= -5x-y

The correct answer is 6 ft

Explanation:

It is known the customer bought 3 identical rugs, which means the size and radio of each rug was the same. Moreover, the total this customer paid for the rugs was $1350, which is equivalent to $450 for each rug as $1350 ÷ 3 = $450.  

Besides this, the black line in the graph shows at $450 (between 400 and 500 in the y-axis) the rugs have a ratio of 6 feet, which is shown in the x-axis as these two values intersect or align to form the black line. This means a carpet with a radius of 6ft costs $450, and therefore each of the rugs the customer bought had a radius of 6ft.

Answer:

Deshaun =  $590 - $35x

Isabel :  $790 - $55x

$590 - $35x = $790 - $55x

Step-by-step explanation:

For  Deshaun :

Amount in her account = $590

Amount she would have withdrawn by month x = $35 × x = $35x

The amount she would have in her account = $590 - $35x

For Isabel :

Amount in her account = $790

Amount she would have withdrawn by month x = $55 × x = $55x

The amount she would have in her account = $790 - $55x

Let x be the time when the money in their account would be equal  =

$590 - $35x = $790 - $55x

Answer:

Length is 10

Width is 8

Step-by-step explanation:

The formula for the perimeter of a rectangle is:

[tex]P=2l+2w[/tex]

We are told that the length l is 2 more than twice the width w. In other words:

[tex]l=2+2w[/tex]

Also, we are given that the perimeter is 28. Therefore:

[tex]P=2l+2w\\28=2(2+2w)+2w[/tex]

Distribute:

[tex]28=4+4w+2w[/tex]

Combine like terms:

[tex]28=4+6w[/tex]

Subtract 4 from both sides:

[tex]6w=24[/tex]

Divide by 6:

[tex]w=4[/tex]

So, the width is 4.

And the length is 2 more than twice the width. Thus:

[tex]l=2+2(4)\\l=2+8=10[/tex]

The length is 10.

And we are done :)

Answer:

Step-by-step explanation:

Answer:

Sales= $90

Expenditures= $90

Step-by-step explanation:

The members of a cooking club are making cakes.

The cakes will be sold at a street fair price of $9 for each cake.

It cost $50 for a booth at the fair.

The ingredients for each cake cost $4

Let y represent the number of cakes that was sold

Since the price of each cake is $9 then,

Sales = $9y

Since the booth cost $50 and ingredients cost $4 then,

Expenditures = $50 + $4y

Sales = Expenditures

9y= 50 + 4y

Collect the like terms

9y-4y= 50

5y= 50

Divide both sides by the coefficient of y which is 5

5y/5= 50/5

y= 10

Sales= 9×10

= $90

Expenditures= $50 + 4(10)

= $50+$40

= $90

Hence the sales is $90 and the expenditures is $90

Your answer is the third option

A linear function has to be added or subtracted by the same number every time. The independent variable is x and the dependent variable is y.

So for side "x" 1 is being added to each number and for side "y"  is being subtracted by 2

Answer:

2[tex]\sqrt{2}[/tex] x

Step-by-step explanation:

The diagonal divides the square into 2 right angles with legs s and hypotenuse x

Using Pythagoras' identity on one of the right triangles, then

s² + s² = x²

2s² = x² ( divide both sides by 2 )

s² = [tex]\frac{x^2}{2}[/tex] ( take the square root of both sides )

s = [tex]\sqrt{\frac{x^2}{2} }[/tex] = [tex]\frac{x}{\sqrt{2} }[/tex]

Thus

perimeter = 4s = 4 × [tex]\frac{x}{\sqrt{2} }[/tex] = [tex]\frac{4x}{\sqrt{2} }[/tex]

Multiply numerator/ denominator by [tex]\sqrt{2}[/tex]

perimeter = [tex]\frac{4x\sqrt{2} }{2}[/tex] = 2[tex]\sqrt{2}[/tex] x

Answer: oop ;-;

Step-by-step explanation: We have two basic equations

A = B + 826         A is 826ft taller than B

A + B = 1516       Combined height is 1516 ft

Replace A with B+826 in 2nd equation and solve for B

B + 826 + B = 1516    Combine like terms

2B + 826 = 1516         Subtract 826 from both sides

2B = 690                    Divide both sides by 2

B = 690/2

B = 345 ft

We know that A = B + 826 so you simply need to do

that addition to have the height of both towers.

Answer:

Choose f(x) = 11x + 1

Step-by-step explanation:

Note that we will simply plug the value of 2 into the equation for February:

f(2) = 11(2) + 1 = 23

And plug the value of 6 into the equation for June:

f(6) = 11(6) + 1 = 67

Note how the points on the graph seem to match up with these values.  If we evaluate following the same style for each:

f(3) = 11(3) + 1 = 34

f(4) = 11(4) + 1 = 45

f(5) = 11(5) + 1 = 56

Note, these values seems to be very close in approximation to the graph points for each month.

The other three functions return values that are just to far away from what are represented in the graph.

Cheers.

Answer:

If MN = XY, and XY = AB, then MN = AB.  Transitive Property

If AB = CD, then CD = AB.  Symmetric Property

Segment CD is congruent to segment CD. Reflexive Property

Step-by-step explanation:

Transitive property states that for all reall numbers a, b, and c, if a = b, b = c, then a = c.

Symmetric Property states that for all real numbers a and b, if a = b, then b = a.

Reflexive Property states that for every real number a, a=a

1. Transitive property

2. Symmetric property

3. Reflexive property

The equivalence properties are Reflexive property, Symmetric property & Transitive property.

Reflexive Property : For every real number a, a=a

Symmetric Property : For real numbers a & b, if a=b then b=a

Transitive Property : For real numbers a, b, c, if a=b & b=c then a=c

1. If MN = XY, and XY = AB, then MN = AB ⇒ Transitive property

2. If AB = CD, then CD = AB ⇒ Symmetric property

3. Segment CD is congruent to segment CD ⇒ Reflexive property

Next, get the outcome of roll two number cubes

Outcome = [tex](1,1)(1,2)(1,3)(1,4)(1,5)(1,6)\ (2,1)(2,2)(2,3)(2,4)(2,5)(2,6)\ (3,1)(3,2)(3,3)(3,4)(3,5)(3,6)[/tex][tex](4,1)(4,2)(4,3)(4,4)(4,5)(4,6)\ (5,1)(5,2)(5,3)(5,4)(5,5)(5,6)\ (6,1)(6,2)(6,3)(6,4)(6,5)(6,6)[/tex]

Next, get the sample space;[tex]S = \{2,3,4,5,6,7, 3,4,5,6,7,8, 4,5,6,7,8,9, 5,6,7,8,9,10, 6,7,8,9,10,11, 7,8,9,10,11,12\}[/tex]

Reorder from lowest to highest[tex]S = \{2,3,3,4,4,4,5,5,5,5,6,6,6,6,6,7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12 \}[/tex]
