The picture shows two sizes of shipping boxes with measurements in inches. The boxes are rectangular prisms. There are two rectangular prisms. Prism 1 has a height of 10 inches, length of 20 inches and a width of 7 inches. Prism 2 is smaller and to the right of Prism 1. Prism 2 has a height of 4 inches, length is 20 inches and width is 4 inches. Marcus shipped 1 of the larger boxes and 2 of the smaller boxes. Which equations show the total volume of the boxes Marcus shipped? Select the three equations that apply.
Using the volume of a rectangular prism, it is found that Marcus shipped 2040 in³ of the boxes.
What is the volume of a rectangular prism?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.

Answer:
99y[tex]d^{2}[/tex]
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

An acute angle is less than 90°.
An acute angle is less than 90° is shown in the second option. Hence, the second option is correct.
What is an acute angle?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 :
Acute angleRight angle Obtuse angleIn 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:
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°

Calculate the shaded area
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

A company is making a steel reinforced concrete tunnel to prevent water from coming into the area. They are going to cover it with a protective coating.
They need to know the surface area of the tunnel to purchase the protective coating.
Calculate the surface area of the tunnel
The surface area of the cylinderical tunnel needed to purchase the protective coating is 452.16cm².
How to calculate the surface area?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.

A city planner wanted to place the new town library at site A. The mayor thought that it would be better at site B. What transformations were applied to the building at site A to relocate the building to site B? Did the mayor change the size or orientation of the library?
The building at site A was translated _______ unit (s)right and _______ unit(s) down, then it was reflected across the x or y (select) - axis.
The size was or was not (select) changed.
The orientation was or was not (select) changed.
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:
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
