What is the scale factor from Figure A to Figure B? PLEASE HELP

Answer:

116 cm²

Step-by-step explanation:

area shaded = total area - area not shaded

πr² is the area of a circle

total area = πr² = π*(6.5cm)² = 132.732289614 cm²

area not shaded = πr² (note the radius is 2.3cm for the non-shaded portion) = π*(2.3cm)² = 16.6190251375 cm²

area shaded = total area - area not shaded = 132.732289614 cm² - 16.6190251375 cm² = 116.113264476 cm² ≈ 116 cm²

Step-by-step explanation:

First find the slope with the equation y/x

80/50=8/5 (you want this in fraction form)

y-80=8/5(x-50)

y-80=8/5x-80

y=8/5x+0

the y-intercept is zero (so place a dot at the origin)

next, go up 8 values and then 5 to the right (5,8), continue to do this process until you have enough points to graph a line. (10,16), (15,24), (20,32)

Hope this helps!

Answer:

  2 right, 4 down, y-axis

Step-by-step explanation:

Reflection across the y-axis changes the left-right orientation. Reflection across the x-axis changes the up-down orientation. Translation before the reflection can put the figure in a place so that the reflection gives its final location. Translation does not affect the orientation.

__

We observe that the north-south wall is on the west side of the building at Site A, and on the right side at Site B. That means the orientation was changed left-to-right, so reflection was across the y-axis.

If the reflection occurred last, then the position before reflection must have the northeast corner moved from (-3, 5) to (-1, 1). That is, the x-coordinate is increased by 2, and the y-coordinate was decreased by 4.

The building at site A was translated 2 units right and 4 units down; then it was reflected across the y-axis .

Answer:

16.30

Step-by-step explanation:

It is 16.30 because 8.65+7.65 = 16.30

Answer:

I believe it is 136° hope it helps

Basically, just plug in the expressions into the formula and simplify:

[tex]A = \frac{1}{2}*(3ab)*(7a^2b+11a^2b) = \frac{3}{2}ab*(18a^2b) = 27a^3b^2[/tex]

An acute angle is less than 90° is shown in the second option. Hence, the second option is correct.

Acute angles are those that are smaller than 90° and fall between 0° and 90°; they are referred to as such. For example, temperatures of 60°, 30°, 45°, and others. An acute triangle is a triangle whose all internal angles are less than 90 degrees. An equilateral triangle is called an acute triangle if its internal angles measure 60°.

There are various types of angles, most commonly they are :

In the second option, the circle is void, which means the angle is less than 90°. As we compare this with the first option the circle is filled, which means that the angle is equal to 90° which means that it is a right angle.

So, this concludes that the second option is correct.

Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{4}{5}[/tex] and c = 0 , thus

y = [tex]\frac{4}{5}[/tex] x ← equation of line

Answer:

  89

Step-by-step explanation:

The arc intercepted by the inscribed 45° angle is twice that, 90°. The angle at x is half the sum of the intercepted arcs, so is ...

  x = (90° +88°)/2

  x = 89°

_____

Alternate solution

The inscribed angle intercepting the 88° arc will have half that measure, so is 44°. The triangle's exterior angle x will be equal to the sum of the remote interior angles:

  x = 45° +44° = 89°

Using the volume of a rectangular prism, it is found that Marcus shipped 2040 in³ of the boxes.

The volume of a rectangular prism of lenght l, width w and height h is given by:

V = lwh.

Prism 1 has dimensions of h = 10, l = 20, w = 7, hence it's volume in cubic inches is given by:

V1 = 20 x 10 x 7 = 1400 in³.

Prism 2 has dimensions of h = 4, l = 20, w = 4, hence it's volume in cubic inches is given by:

V2 = 20 x 4 x 4 = 320 in³.

Marcus shipped 1 of the larger boxes and 2 of the smaller boxes, hence the total volume is of:

V = V1 + 2V2 = 1400 + 2 x 320 = 2040 in³.

The surface area of the cylinderical tunnel needed to purchase the protective coating is 452.16cm².

Your information is incomplete. Therefore, an overview of the surface area of a cylindrical tunnel will be given.

Let's assume that the radius is 4cm and the height is 7cm. The surface area of the tunnel will be:

= πr²h + 2πr²

= (3.14 × 4² × 7) + (2 × 3.14 × 4²)

= 351.68cm + 100.48cm

= 452.16cm²

In conclusion, the surface area is 452.16cm².

Step-by-step explanation:

Answer:

90yd²

Step-by-step explanation:

Area pf trapezium = 1/2 * (sum of parallel sides) * perdendicular distance b/w them.

Here,

Sum of II sides = 11 + 9yd = 20yd

Perpendicular distance = 18 yd

So, area of trapezium is

1/2 * 20yd * 18yd = 180yd²

As the triangle inscribed is right - angled triangle, area of ∆ = 1/2 * 10yd * 18yd = 90yd²

Shaded area = total area - area of ∆

= 180yd² - 90yd²

= 90yd²
