Ronnie wants to buy a computer table that measures 10 feet by 17 feet. The cost of the table is 16.00 per square feet. How much will it cost Ronnie to buy the computer table for his study room?

Answers

Measurement of table:
Length=17 feet
Width=10 feet
As we know that the table will be in rectangular shape.
So, Area of table= 10 feet × 17 feet
170 squared feet.
A/Q,
Cost of 1 square feet table =16($ or any unit of currency)
Cost of 170 square feet= 16×170($)
2720($)

The given dimensions are 10 ft and 17 ft
Now looking at the dimensions, we can assume it is rectangular in shape and therefore the formula of the area of a rectangle is:
Area = length × width
(length = 17 ft (longest side) and width = 10 ft)
1st step: Substitute the dimensions in the formula:
A = L × W
= 17 × 10 (order doesnt matter!)
= 170 ft²
Coming to the cost, 1 ft² costs 16 (lets keep it £, or €, or $, since the unit is not provided)
2nd step: We multiply the area by the cost to find the total amount!
(Because every squared feet is 16 and therefore we conclude with this formula)
Cost = 170 ft² × 16£
= £2,720
Ronnie will have to pay £2,720 (or any other currency units)

Sarah has completed the first few steps for constructing the inscribed circle for triangle ABC. She started by constructing the angle bisectors for angles A and C. This gives her the incenter (point D). What is the next step?

Answers

The nest step is to Construct the altitude from the incenter to a side of the triangle and label the intersection point. (: but next time I'd highly recommend (if you can) add an attachment describing your question, hope this is helpful though.

Answer:

D) Construct the altitude from the incenter to a side of the triangle and label the intersection point.

Use the figure below to answer the questions.a. What is the name of the 3D shape?

b. What is the formula for total surface area for this shape?

c. What is the surface area of the figure?

Answers

Answer:

a. What is the name of the 3D shape?

The name of the 3D shape is Prism

b. What is the formula for total surface area for this shape?

Total surface area:

$S=2A_(b)+P_(b)h$

c. What is the surface area of the figure?

The surface area of the figure is 144 cm²

Step-by-step explanation:

a. What is the name of the 3D shape?

The 3D shape has two congruent and parallel faces (triangles) and the other faces are parallelograms, then the 3D shape is a prism

b. What is the formula for total surface area for this shape?

Total Surface area:

$S=2A_(b)+P_(b)h$

where:

Area of the base of the prism: Ab

Perimeter of the base: Pb

Height of the prism: h

c. What is the surface area of the figure?

The base of the prism is a triangle. Then to calculate the area of the base, we must use the formula to calculate the area of a triangle:

$A_(b)=(bh)/(2)\n A_(b)=((4 cm)(3 cm))/(2)\n A_(b)=(12cm^(2) )/(2)\n A_(b)=6cm^(2)$

The perimeter of the base is the perimeter of the triangle, equal to the sum of the sides of the triangle:

$P_(b)=4cm+3cm+5cm\n P_(b)=12cm$

h: Height of the prism is the distance between the bases of the prism (the triangle), then h=11 cm

Then, replacing in the formula the known values:

$S=2(6 cm^(2))+(12 cm)(11 cm)\n S=12 cm^(2)+132 cm^(2)\n S=144 cm^(2)$

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio of the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

Answers

From the steps Talia chooses to find the equation of the line, we shall evaluate the incorrect step as follows:
Step 1:
Choose a point in the line such as (2,5)
Step 2:
Choose another point on the line, such as (1, 3)
step 3:
Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
(5-3)/(2-1)=2/2=1
step 4:
Substitute those values into the point-slope form
y-y1=m(x-x1)
y-3=2(x-1)
y=2x+1
Thus the answer is:
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

just took the test the right answer is step 3 is incorrect
