When teaching measurement to a student with a visual disability, use tactile materials, auditory cues, non-visual measurement tools, real-world examples, and encourage peer collaboration.
Explanation:When teaching measurement to a student with a visual disability, it is important to use alternative methods of instruction that focus on touch and auditory experiences. Here are some strategies you can use:
Provide tactile materials: Allow the student to explore three-dimensional geometric shapes with their hands. You can use manipulatives or 3D models to enhance their understanding.Use auditory cues: Describe the measurements using clear and precise language. For example, instead of saying 'This object is 5 centimeters long', say 'This object is as long as five paperclips.' This helps the student form a mental image.Include non-visual measurement tools: Utilize tools like braille rulers, talking calculators, or measuring tapes with tactile markings. This allows the student to independently measure objects.Provide real-world examples: Relate measurements to everyday situations. For example, you can discuss the length of a classroom desk or the volume of a water bottle. This helps the student connect measurement concepts to their own experiences.Encourage peer collaboration: Pair the student with a sighted buddy who can assist them during hands-on activities. This promotes inclusive learning and allows the student to engage with their peers.Learn more about How to adjust instruction for a student with a visual disability in math measurement lessons here:https://brainly.com/question/39515127

A train travels train travels 288 kilometre at a uniform speed. If the speed had been 4 kilometre per hour more it would have taken 1 hour less for the same journey. Find the speed of the train
Answer:
Let the speed of the train be x km/h.
Case 1:
Distance = 288 km
Speed = x km/h
Time = Distance/Speed
= 288/x h
Case 2:
Distance = 288 km
Speed = (x+4) km/h
Time = 288/x + 4 h
Since 288/x > 288/x + 4
288/x - 288/x+4 = 1
288[1/x - 1/x+4 ] = 1
[ x + 4 - x / x(x + 4) ] = 1/288
[4 / x^2 + 4x ] = 1/288
x^2 + 4x = 1152
x^2 + 4x - 1152 = 0
x^2 + 36x - 32x - 1152 = 0
x(x + 36) - 32(x + 36) = 0
(x + 36)(x - 32) = 0
x + 36 = 0 , x - 32 = 0
x = -36 , x = 32
x = -36 , rejected since speed cannot be negative.
Therefore , speed of the train = 32 km/h

What is the perimeter of a rectangle where the area is 35 sq inches, (the length is 7inches and the width is 5 inches)?
Answer:
The perimeter is 24 sq inches.
Step-by-step explanation:
In order to find perimeter, you must add together all the sides. So the equation would be (LxW)2 , or just Length plus Length plus Width plus Width. Therefore, it is either (7x5)2 or 7 + 7 + 5 + 5 which both equal 24 sq inches. Hope this helps!
The perimeter of a rectangle with an area of 35 square inches, length of 7 inches, and width of 5 inches is calculated using the formula P = 2l + 2w, resulting in a perimeter of 24 inches.
Explanation:To calculate the perimeter of a rectangle when given the area and the dimensions, we use the formula P = 2l + 2w, where 'P' represents the perimeter, 'l' is the length, and 'w' is the width of the rectangle. If we know the length is 7 inches and the width is 5 inches, we can plug these values into the formula to find the perimeter:
P = 2(7) + 2(5) = 14 + 10 = 24 inches.
Therefore, the perimeter of the rectangle with an area of 35 square inches, length of 7 inches, and width of 5 inches is 24 inches.

Answer:
41.5 ft
Step-by-step explanation:
From the information given, and definition of midpoint, we know that:
AB = BC = ½ AC
AC = CE = ½ AE
CD = DE = ½ CE
GF = FE = ½ GE
HG = GE = ½ HE
AI = IH = ½ AH
AJ = JI = ½ AI
We also know:
AH = 20
HE = 14
GD = 4
Therefore:
AI = IH = 10
HG = GE = 7
AJ = JI = 5
GF = FE = 7/2
Next, since JB and IC are parallel with HE, we know that AJB and AIC are similar to AEH. So:
JB / 5 = 14 / 20
JB = 7/2
IC / 10 = 14 / 20
IC = 7
And since DF and CG are parallel to AH, then DFE and DGE are similar to AHE. So:
DF / (7/2) = 20 / 14
DF = 5
CG / 7 = 20 / 14
CG = 10
Next we know that AIB and AHC are similar, and DEG and CEH are similar.
IB / 10 = CH / 20
CH / 14 = 4 / 7
CH = 8, IB = 4.
We've found all the lengths inside triangle AEH. Adding them up:
JB + IB + IC + CH + CG + DG + DF
7/2 + 4 + 7 + 8 + 10 + 4 + 5
41.5
The total length of the inside bars is 41.5 ft.
A regular octagon has side length 10.9 in. The perimeter of the octagon is 87.2 in and the area is 573.67 in2. A second octagon has side lengths equal to 21.8 in. Find the area of the second octagon. Round to the nearest hundredth.
Answer:
2,294.66 square inches
Step-by-step explanation:
The area of an octagon is given by the formula:
A = 2 * a² * ( 1 + √2 )
So, if we input the numbers we have:
A = 2 * 21.8² * ( 1 + √2 )
A = 2 * 475.24 * (2.4142)
A = 2,294.66 square inches
As you can see, if you double the side of an octagon, its area will quadruples, which is logic since the one variable in the calculation of the area is the side's length... that is squared. So, if you double it, that double factor is squared.
It's as if we had written
A = 2 * (10.9 * 2)² * ( 1 + √2 )
A = 2 * (10.9² * 2²) * ( 1 + √2 )
If the area of the base of one cylinder is 452.16 square units, and the radius of another cylinder is 12 units, which additional fact must be true for the volumes of the two cylinders to be equal? (Use = 3.14)
A. The heights of each cylinder must be the same.
B. The areas of the base of each cylinder must be the same.
C. The circumferences of the base of each cylinder must be the same.
D. The radii of the base of each cylinder must be the same.
Answer: C. the circumferences of the base of each cylinder must be the same
Step-by-step explanation:
Check the picture below.
so we know that the area of the base of the 1st cylinder is 452.16, and the radius of the 2nd cylinder is 12, hmmm what is the radius of the 1st cylinder anyway?
[tex]\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} A=452.16 \end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2 \\\\\\ \stackrel{\pi =3.14}{\cfrac{452.16}{3.14 }}=r^2\implies 144=r^2\implies \sqrt{144}=r\implies 12=r[/tex]
low and behold, the radius of the 1st one is 12 as well, so both cylinders have the same radius. Let's recall the volume of a cylinder is V = πr²h.
now if they can just have the same height, they'd both have the same volume.

You save $8,500.00. You place 40% in a savings account earning a 4.2% APR compounded annually and the rest in a stock plan. The stock plan decreases 3% in the first year and increases 7.5% in the second year. What is the total gain at the end of the second year for both accounts combined?
Answer:
The total gain at the end of the second year for both accounts combined is $509.09.
Step-by-step explanation:
Amount saved = $8500
40% of 8500 is saved in saving account; [tex]0.4\times8500=3400[/tex]
Remainder amount in stock plan; [tex]8500-3400=5100[/tex]
Working for savings plan:
[tex]A=p(1+\frac{r}{n})^{nt}[/tex]
Here, p = 3400 ; n = 1 , t = 2 , r = 0.042
Putting values in formula:
[tex]A=3400(1+\frac{0.042}{1})^{2}[/tex]
[tex]A=3400(1+0.042)^{2}[/tex]
A = $3691.60
We get a gain of [tex]3691.60-3400=291.60[/tex] dollars
Working for stock plan:
The stock plan decreases 3% in the first year and increases 7.5% in the second year.
[tex]5100\times 0.97=4947[/tex]
When increases;
[tex]4947\times1.075=5318.03[/tex] dollars
So, we get a gain of [tex]5318.03-5100=218.03[/tex] dollars
Therefore, we have a total gain of [tex]291.06+218.03=509.09[/tex] dollars.

There are 125 people and 57 of the people have pets. What percent of people have pets.
First, we need to understand what the question is asking us to do. We know that there are 125 people altogether and only 57 of the people have pets. We are trying to figure out what percent of the people have pets.
The fraction [tex]\frac{57}{125}[/tex] is representing the 57 people who have pets out of all the people. To find what percent of people have pets, we have to change [tex]\frac{57}{125}[/tex] to a percent.
57 ÷ 125 = 0.456
0.456 × 100 = 45.6%
Therefore, 45.6% of people have have pets.

Step-by-step explanation:
Unfortunately, there is no shortcut to solve these... you have to do the work, iteration by iteration.
A recursive function is a function that calls itself and takes as input the output of the previous call.
a = -2 a + 4
a1: 1
a2: -2 (1) + 4 = -2 + 4 = 2
a3: -2 (2) + 4 = -4 + 4 = 0
a4: -2 (0) + 4 = -0 + 4 = 4
a5: -2 (4) + 4 = -8 + 4 = -4
a6: -2 (-4) + 4 = 8 + 4 = 12
a7: -2 (12) + 4 = -24 + 4 = -20

What are the vertex and X intercepts of the graph of the function below y=(x-4)(x+2)
Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
x- intercepts are x = - 2 and x = 4
The vertex lies on the axis of symmetry which is located at the midpoint of the x- intercepts, thus
[tex]x_{vertex}[/tex] = [tex]\frac{-2+4}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = (1 - 4)(1 + 2) = - 3 × 3 = - 9
vertex = (1, - 9)
The x-intercept of the line will be x = 4 and x = -2 and Vertex = (1, - 9).
What is x-intercepts and vertex?The x-intercepts are the points where the graph intersects the x-axis. The vertex is the point that defines the minimum or maximum of a parabola.
We have,
y = (x - 4) (x + 2)
Now,
So, to get the x-intercept,
Put y = 0,
i.e.
0 = (x - 4) (x + 2)
NOw,
x - 4 = 0
⇒ x = 4,
And,
x + 2 = 0
⇒ x = -2
So,
x-intercepts are x = 4 and x = -2.
Now,
To get the vertex ,
For vertex,
The vertex lies on the axis of symmetry which is located at the midpoint of the x- intercepts, thus
Vertex for x [tex]=\frac{-2+4}{2}=1[/tex]
Now,
Substitute x = 1 into the equation,
i.e.
y = (1 - 4)(1 + 2)
= - 3 × 3 = - 9
So,
Vertex = (1, - 9)
Hence, we can say that the x-intercept of the line will be x = 4 and x = -2 and Vertex = (1, - 9)
