The area of the rhombus ABCD is 24.7 cm².
The length of diagonal BD is 6.5 cm.
What is the area of a rhombus?A rhombus have equal four sides and the diagonals of the rhombus divides it into four equal right triangles. The area of the rhombus is the sum of individual areas of the four right triangles.
The hypotenuse side of the right triangle = side of the rhombus = BC = 5 cm
One of the legs of the right triangle = AO = OC = 3.8 cmLet the second leg of the right triangle = OB = OD = xThe second leg of the right triangle is calculated as follows;
[tex]x^2 + 3.8^2 = 5^2\\\\ x^2 = 5^2 - 3.8^2 \\\\ x^2 = 10.56\\\\ x = \sqrt{10.56} \\\\ x = 3.25 \ cm[/tex]
The area of one right triangle of the rhombus is calculated as follows;
[tex]A = \frac{1}{2} (3.8)(3.25)[/tex]
The area of the rhombus ABCD is calculated as follows;
[tex]A = 4 \times \frac{1}{2} (3.8)(3.25)\\\\ A = 24.7 \ cm^2[/tex]
The length of diagonal BD is calculated as follows;
[tex]BD = OB \ + \ OD\\\\ BD = x \ + \ x\\\\ BD = 3.25 \ cm \ + \ 3.25 \ cm\\\\ BD = 6.5 \ cm[/tex]

company decided to use 15 people. Assume all people have the same level of productivity.
In how many days can this project be completed?
SELECT ONLY ONE
5 days
10 days
22.5 days
45 days
Given:
45 people will accomplish the given task in 15 days.
To find:
Days taken by 15 people to complete the same task.
Solution:
Since, 45 people of a company can finish a work in 15 days
Therefore, 1 person can accomplish the task in days = [tex]15\times45[/tex]
= [tex]675[/tex] days
15 people will accomplish the same task in number of days = [tex]\frac{675}{15}[/tex]

A rectangular prism has a length of 112feet, a width of 212feet, and aheight of 8 inches. What is the volume of the prism in cubic inches?
pls hurry :)
Answer:
27,353,088 cubic inches
Step-by-step explanation:
How to find the volume of a rectangular prism
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Solve
In this case, The volume of a rectangular prism with a length of 112feet,
width of 212 feet, and height of 8 inches:
But in this case, we need to convert both the length and width to inches.
If 1ft = 12in
Then, 112ft = 1344in (Multiply 112 by 12)
Also, 212ft = 2544 (Multiply 212 by 12)
So, the volume = 1344 x 2544 x 8
Calculated out this gives a volume of 27,353,088 cubic inches.

Answer:
I think its 5x²-27x+10
Step-by-step explanation:
Area of trapezium:
a+b/2× h
So substitute into the formula:
4x - 1 + 6x - 3 /2 × (x - 5)
1. 4x - 1 + 6x - 3 (collect all like terms)
4x + 6x + -1 -3 = 10x - 4
2. 10x - 4 / 2
= 5x - 2
3. 5x - 2 × x - 5
Use FOIL:
5x ² - 25x - 2x + 10
= 5x ² - 27x +10

Answer:
11.25 or 11 1/4
Step-by-step explanation:
seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole
so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-
now we need the dimensions of each one-
rectangle one
l=5 w=2
rectangle two
l=5 w=1/4
now let us set up the equation and solve-
a=lw
rectangle one
a=5*2=10
rectangle two
a=5*1/4=1.25
and the last step is to add together the areas of both rectangles
10+1.25=11.25
and since you need your answer as a mixed number the answer is 11 1/4
(to do this you just put 11.25 over 100 and then simplify)
good luck :)

Allison designs fancy boxes to fill with chocolates. The boxes are in the shape of a right square pyramid as shown, where 8y represents the
length of one side of the base of the pyramid, and 5y represents the height of one triangular face of the pyramid.
8y
The large size box must be designed to have a volume of 1,000 cubic centimeters,
Create an equation that can be used to calculate the length of the base and height of the triangular face of the box. Enter your equation in
the first response box.
The requreid equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The formula for the volume of a square pyramid is:
V = (1/3) * base area * height
In this case, the base of the pyramid is a square with a side length of 8y, so the base area is:
base area = (8y)² = 64y²
The height of each triangular face is given as 5y, so the total height of the pyramid is 2 * 5y = 10y.
Substituting these values into the formula for volume, we get:
1000 = (1/3) * 64y² * 10y
y ≈ 1.16
Therefore, the length of the base of the pyramid is:
8y ≈ 8.4
And the height of each triangular face is:
5y ≈ 5.8 cm
So the equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm
