right and isosceles but not equilateral

Answer:

D.

Step-by-step explanation:

If you trying to find 1/7 of a number, divide by 7.

780,000/7 = 111428

It says approximately so it won't be the exact answer

Answer:

144

Step-by-step explanation: You add both of the bases in which this case would be 12 and 6, giving you 18, multiply it by the height, 16, to give you 288 then divide it by 2.

The independent variable is the time of the visit

The dependent variable is the total service charge, this depends on the amount of time spent working in the house

Answer:

(x + 6y)(x - 3y)

Step-by-step explanation:

Given

x² + 3xy - 18y²

Consider the factors of the coefficient of the y² term (- 18) which sum to give the coefficient of the xy- term (+ 3)

The factors are + 6 and - 3 , since

6 × - 3 = - 18 and 6 - 3 = + 3 , then

x² + 3xy - 18y² = (x + 6y)(x - 3y)

Answer:

4/5

Step-by-step explanation:

The slope is always the coefficient of x in a y = mx + b equation

Answer:

[tex] \huge\mathfrak\pink{S} \huge\mathfrak\purple{o} \huge\mathfrak\blue{l} \huge\mathfrak\red{u} \huge\mathfrak\green{t} \huge\mathfrak\pink{i}\huge\mathfrak\purple{o}\huge\mathfrak\red{n}\huge\mathfrak\orange{:}\ [/tex]

y=[tex] \frac{4}{5} [/tex]x-3

comparing above equation with y=mx +c

we get

slope[m]=[tex] \frac{4}{5} [/tex]

Let length, width, and height be s.

Then diagonal of any face would be √( s² + s² ) = √( 2s² )

And we know that it measures  √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.

Now we have to solve √( 500 ) = √( 2s² )

Square both sides:

500 = 2s²

Divide both sides by 2:

250 = s²

Take the square root of both sides:

√(250) = s ≈ 15.8113883

Rounding to nearest tenth:

s ≈ 15.8

Final answer: 15.8

Hope this helps.

Answer:

The person above me is correct

Step-by-step explanation:

The shape is a pentagon.

The interior angles of a pentagon always add up to 540°.

When you add up all the labeled angles in the picture, you get (16x + 12).

16x + 12 = 540

16x = 528

X = 33

Step-by-step explanation:

4x-25+3x+25+3x+15+4×+2x-3=360

4x+3x+3x+4x+2x-25+25+15-2=360

16x +12=360

16x=360-12

16×÷16=348÷16

×=21.75

Answer: c

Step-by-step explanation: there is already 1/4 of the pie and we know that 80 people have chosen 80, so the 3 left have to add up to 240.

Step-by-step explanation:

[tex]A=\frac{(bx_{1}+bx_{2} )h }{2}[/tex]

[tex]A=\frac{(7.7+14.3)(8.6)}{2}[/tex]

[tex]answer:- 94.6 ft^{2}[/tex]

[tex]---------[/tex]

hope it helps...

have a great day!!

Answer:

area = 94.6 ft.sq

Step-by-step explanation:

here's your solution

==> area of trapezium = 1/2*(sum of parrel side)*distance between them

==> area of trapezium = 1/2(7.7 + 14.3)*8.6

==> area of trapezium = 1/2*22*8.6

==> area = 11*8.6

==> area = 94.6 ft.sq

hope it helps

Answer:

[tex]7^{\frac{1}{2} }[/tex]

Step-by-step explanation:

because when x-coordinate equals zero we will have a one value for y

Given:

In a triangle,

[tex]a=7,b=24,c=25[/tex]

To find:

Whether the given segments are the sides of a right triangle or not.

Solution:

In a right triangle the square of largest side is equal to the sum of squares of two smaller side.

[tex]c^2=a^2+b^2[/tex]                 (Pythagoras theorem)

Three sides are [tex]a=7,b=24,c=25[/tex]. Here, 25 is the largest side.

[tex]25^2=625[/tex]

Now, the sum of squares of two smaller sides is:

[tex](7)^2+(24)^2=49+576[/tex]

[tex](7)^2+(24)^2=625[/tex]

[tex](7)^2+(24)^2=25^2[/tex]

Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.

Answer:

the yellow one? not sure tho

Step-by-step explanation:

Answer:

the last one (pentagon)

Step-by-step explanation:

the triangle already has 3 vertices and 3 sides and if she wants to have 8 vertices and 8 sides in total, the second shape would have 5 vertices and 5 sides. therefore, it's the pentagon

Answer:

x=-3 is not a solution

Step-by-step explanation:

well, lets plug it and and see!

6(-3)-19=3(-3)-10

-18-19=-9-10

-37=-19

-37 DOES NOT equal -19.

so x=-3 is not a solution

hope this helped! :)
