SOLVE ASAP PLEASE Point theif = ban
Answer:
Given dimensions of room:
length = 12 ftwidth = 14 ftheight = 8 ftGiven cost of materials:
floor tiles = $4 per ft²wall & ceiling paint = $16 per 146 ft²Total square feet of floor = length × width
= 12 × 14
= 168 ft²
Total cost of flooring = $4 × 168
= $672.00
Total square feet to be painted = area of walls + area of ceiling
= 2(12 × 8) + 2(14 × 8) + (12 × 14)
= 584 ft²
Total cost of paint = (584 ÷ 146) × $16
= $64.00
Total cost to tile and paint the room = $672 + $64
= $736.00
help me please, need answer quick
Answer:
Option D is correct
The answer is 42 square unit.
Step-by-step explanation:
Given;a = 9 unitsb = 12 unitsh = 4 unitsTo Find;Area of TrapezoidFormula;Area = ½ (a + b) × hNow,
A = ½ (a + b) × h
A = ½ (9 + 12) × 4
A = (21) × 2
A = 42 square unit
Thus, The estimated area of the Trapezoid is 42 square unit.

Riley has completed 6 of the 30 pages she was assigned for homework. What percentage of her homework does Riley have left to complete?
Answer:
80 Percent
Step-by-step explanation:
Since she has done 6/30 pages, she has 24/30 more pages to complete. Convert 24/30 to a decimal by dividing 24 by 30 to get the percentage, which is 80 percent

Andre sold 43 magazines at his mom's work, 32 at his dad's work, 18 around his
neighborhood, and 3 at home. What is the mean of the magazines he sold?
Answer:
The mean is 24 ( I think)
Step-by-step explanation:
SO in all, there were 96 magazines sold. So if there are just those 4 categories divide the 96 by 4. 96 divided by 4 = 24.
The mean of magazines he sold is 24

How does Algebra act as a tool to improve communication
It is a tool as it represents the language of patterns.
It is also a means of working with abstract notions and then applying them, which frequently leads to the formation of generalisations and insights outside of the original context.

find the area of circle o if DCBO is a rectangle and DB measure 10 units
Answer:
[tex]100\pi[/tex]
Step-by-step explanation:
Step 1: Identity the radius.
Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,
OC=OE.
Step 2: Consider the rectangle.
All diagonals in a rectangle are congruent so this means
DB= OC ( OC is also a diagonal).
Thus, OC= 10 units.
Step 3: Analyze
So this means OE is also 10 units as well.
Since we know the length of the radius, Use the area of circle,
[tex]\pi {r}^{2} [/tex]
[tex]\pi( {10}^{2} ) = 100\pi[/tex]
So the area of a circle is 100 pi.
Answer:
314.2 square units
Step-by-step explanation:
The diagonals of a rectangle are the same length, so segment OC is the same length as segment DB: 10 units. OC is a radius of the circle, which means the circle's radius is 10 units.
The area of a circle is given by ...
A = πr²
A = π(10 units)² = 100π units²
A ≈ 314.2 units²
The area of circle O is about 314.2 square units.

what is the equation of the following graph?
Answer:
Step-by-step explanation:
When figuring out the graph of a sinusoidal, I keep in mind the acronym FPARHM:
F - function (sine or cosine)
P - period
A - amplitude
R - reflections
H - horizontal/phase shift
M - midline
Looking at the graph, we can figure out that the function is sine (since it intersects the origin at its midpoint, the period is [tex]\pi[/tex] (because it repeats every [tex]/pi[/tex] units in the x-direction, the amplitude is 2 (because the graph's extreme points are 2 units away from the midline in the y-direction, there are no reflections, no horizontal/phase shift, and the midline is [tex]y=0[/tex] (since the graph isn't shifted up or down in the y-direction.
Finally, knowing all these parts, we can piece together the equation of the sinusoidal graph. In general, the equations of sinusoidal graphs are in the form [tex]y=a\sin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex] \frac{2\pi}{|b|}[/tex] is the period, [tex] \frac{c}{b}[/tex] is the horizontal shift, and [tex]d[/tex] is the midline. Additionally, if [tex]a[/tex] is negative, the graph needs to be reflected over the x-axis and if [tex]b[/tex] is negative, the graph needs to be reflected over the y-axis. Knowing this, all we need to do is plug in the amplitude, period, phase shift, and midline to the equation. The equation is [tex]y=2\sin(2x)[/tex]

A theme park has a ride that is located in a sphere. The ride goes around the widest circle of the
sphere which has a circumference of 489.84 yd. What is the surface area of the sphere? Use 3.14
for
The surface area of the sphere is about yd?.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
Answer:
76,400
Step-by-step explanation:
I think this is right, not sure though.
Surface area of sphere:
[tex]4\pi \times r {}^{2} [/tex]
Circumference :
[tex]2(\pi \times r)[/tex]
489.84 = 2 × 3.14 × r
2 × 3.14 = 6.28
489.84 = 6.28 × r
radius = 489.84 ÷ 6.28
R =78
Surface Area = 4 × 3.14 × (78)^2
Surface area = 76,415.04
= 76,400

Work out the volume of the sphere.
Give your answer correct to 1 decimal place.
Volume of sphere= tr3
cm3
Answer:
65449.8 cm3
Step-by-step explanation:
We start with the volume formula for a sphere: 4/3 πr3
We start with subbing in 25 to r, then we cube 25, which is equal to 15625.
We multiply 4/3 and pi. And lastly we multiply what we got by 15625 and either round the answer or fphaving fixed your calculator.
