Answer:

8feet

Step-by-step explanation:

Given the equation that models the arch of a school expressed as;

[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]

If the x axis represents the ground;

At the ground level, x = 0

Substitute x = 0 into the equation to get y;

y = -0.5(0+4)(0-4)

y = -0.5(4)(-4)

y = -0.5 * -16

y = 8ft

Hence the y axis at the ground level is 8feet

Answer:

60 degrees

Step-by-step explanation:

As the triangle is similar angle don't change so 50+70=120 and the angle of a triangle total to 180 so 180-120=60

Answer:

60°

Step-by-step explanation:

As it is said that the triangles are similar so In the similar triangles corresponding angles are equal so

< A = 50°

<E = 70°

< B = < E = 70° { being corresponding angles of similar triangles }

Now

< A + <B + < C = 180° {Being sum of angles of triangle }

50° + 70° + < C = 180°

< C = 180° - 120°

< C = 60°

Answer:

A

Step-by-step explanation:

slope of line ⊥ to the line 4x-2y=6 or 2y=4x-6 or y=2x-3 is -1/2

eq. of line through (6,-8) with slope -1/2 is

y+8=-1/2(x-6)=-1/2 x+3

or y=-1/2 x+3-8

or y=-1/2 x-5

Answer and Step-by-step explanation:

10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.

The equations are:

Blank 1: 3x + 10

Blank 2: 2x + 20

To find when they are equal, we equal the equations together.

3x + 10 = 2x + 20

x = 10

Plug 10 into either equation and solve.

Blank 3: 10 (At 10 miles, the equations are equal)

Blank 4: $40 (The will equal $40)

Answer:

867/4 in3

Step-by-step explanation:

v= l*w*h= 12* 17/4* 17/4

= 51*17/4 = 867/4 in3

if my answer helps please mark as brainliest.

Answer:

[tex]V=216\frac{3}{4} in^{3}[/tex]

Step-by-step explanation:

The formula for volume of a rectangular prism is V = w × h × l, where

V represents the volume

w represents width

h represents height

l represents length

So, all we have to do to find volume is multiply these three values together, like this:

V = 12 × [tex]4\frac{1}{4}[/tex] × [tex]4\frac{1}{4}[/tex]

[tex]V=(12)(\frac{17}{4} )(\frac{17}{4} )[/tex]

Then we multiply all the numerators:

[tex]V =\frac{867}{4}[/tex]

[tex]V=216\frac{3}{4} in^{3}[/tex]

Step-by-step explanation:

AB = 5

AC = 6

BC = √(5² + 6²) = √61 ≈ 7.8 units

Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Answer:

57

Step-by-step explanation:

if 1 = 123 degrees, and the angles add up to 360, then 6 would be 57. Because you would do 123 is 5 and 8, and so 246 is adding those angles. So now you have 7 and 6. 360 - 246 is 114, and since 7 and 6 are equal, just divide that by 2

Answer:

1 foot

Step-by-step explanation:

1 meter = 3 feet

3 feet divided by 3 = 1 foot

The length of each section of the rope is 1 foot.

The piece of rope is 1m long.

Carter divided the ropes into three equal parts by tying up the knot.

1 meter = 3 foot.

Therefore, divide 3 by 3.

[tex]\frac{3}{3} =1[/tex] foot.

Therefore, each section is 1 foot long.

Answer: The answer is 8 lb for $18.80

That is the answer because you have to divide in order to see which is the best buy

You have to divide $4.98 by 2lb and you will get 2.49, divide $12.25 by 5lb which equals 2.45, divide $18.80 and you will get 2.35, divide $23.70 by 10lb and you will get 2.37. So therefore you answer is C.8lb for $18.80 because 2.35 is better than the other deals.

Step-by-step explanation:

Hi!

Here is your answer,

I will explain in step by step,

[tex] {x}^{9} = {12}^{2} \times {12}^{7} [/tex]

Here we can simplify this further using this law,

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

So we will get,

[tex] {x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9} [/tex]

Since the powers are same we can cancel it out and we will get,

Answer:

600

Step-by-step explanation:

Area of Square:

= l*w

= 20x20 = 400

Area of Triangle:

= b*h/2

= 20*20/2

= 200

400 + 200 = 600

Good luck! <3

Answer:

The total area of the shape is 600 square centimetres.

Step-by-step explanation:

You can solve this by finding the area of the square and the triangle separately.

The area of any rectangle, including squares, is width times height. The bottom square then has an area of 20cm × 20cm, which equals 400cm²

The area of a triangle is have of its base width times its height.  It too has a width of 20cm and a height of 20cm, so its area is 20cm × 20cm ÷ 2, which equals 200cm²

Add them together for the full area of the shape:

400cm² + 200cm² = 600cm²

Answer:
