A scale drawing of a square object has a scale of 1 in. : 8 mm. The scale drawing has a length of 6 inches. Find the perimeter and the area of the object in the scale drawing. Then find the perimeter and area of the actual object.
The perimeter of the actual object is 67.2 mm.
The area of the actual object is 282.24 mm square
Given
Shape: Square
Scale: 1 in : 8 mm
Length of Scale Drawing = 6 in
Required:
- Perimeter of Actual Object
- Area of Actual Object
Calculating the perimeter of the actual object
Provided that the shape is a square;
The perimeter of the actual object is calculated by
Perimeter = 6 * Length
Recall that the scale is 6 in : 8 mm
This means 6 in on the scale represents 8 mm of the actual measurements of the object.
So, if 6 in ≈ 8 mm, then
6.8 in ≈ 6.8 * 8 mm
6.8 in = 16.8 mm
So, Length = 16.8mm
Now, the perimeter of the actual object can be calculated.
P = 4 * 16.8mm
P = 67.2mm
Hence, the perimeter of the actual measurements is 67.2 mm.
Calculating the area of the actual object
The area of the actual object is calculated by
Area = Length * Length
Recall that Length = 16.8 mm as calculated above
So,
Area = 16.8 * 16.8
Area = 282.24 mm square
Hence, the area of the actual object is 282.24 mm square

solve the equation 4+3x-1/2=9 .Explain the reasons why you chose your solution method.
Answer:
x = 5
Step-by-step explanation:
that would look like this:
[tex]\frac{4+3x-1}{2}=9[/tex]
first, to remove the denominator (2), we should multiply both sides by 2. therefore, we get:
4 + 3x - 1 = 18.
now, we transpose 4 and -1 to the other side, in order to isolate 3x.
3x = 18 + 1 - 4
3x = 15
to find x, we divide both sides by 3. therefore, we get:
x = 5
Answer:
Step-by-step explanation:
[tex]4 + 3x - \frac{1}{2}=9[/tex]
Subtract 4 from both the sides
[tex]3x - \frac{1}{2}=9 - 4\\\\3x - \frac{1}{2}= 5[/tex]
Add (1/2) to both sides
[tex]3x = 5 + \frac{1}{2}\\\\3x = \frac{5*2}{1*2}+\frac{1}{2}\\\\3x=\frac{10}{2}+\frac{1}{2}\\\\3x=\frac{10+1}{2}\\\\3x=\frac{11}{2}\\\\x=\frac{11}{2*3}\\\\x=\frac{11}{6}[/tex]

yuson must complete 30 hours of community service. she does 2 hours each day. which linear equation represents the hours yuson has left after x days?
Answer:
30-2x
Step-by-step explanation:
yuson has to finish am total of 30 hours in community service
she does 2 hours each day
in x days, hour of service done=2x
after x days hours of service left=30-2x
therefore the linear equation representing the hours yuson has left after x days is:
30-2x
How do I solve this? I need step by step
y=2x
x=-y+6
Notice that y = 2x, which means you can replace any y and turn them into 2x
x = -y + 6
x = -(2x) + 6
Move the x terms to the left and change the sign
x + 2x = 6
3x = 6
x = 2
Now that you know x, substitute them back into the first y = 2x
y = 2(2)
y = 4
Answer: x = 2, y = 4
Jake bought some blueberries for $6 per pound and some strawberries for $4 per pound. He spent a total of $36. Which graph represents all the possible combinations of blueberries (b) and strawberries (s) that Jake could have bought?
The equation for the all-out number of blueberries and strawberries.
6x + 4y = 36
An equation is a mathematical explanation that is comprised of two expressions associated with an equal sign.
2x + 3 = 9 is an equation.
We have,
Cost of one pound of blueberries = is $6
Number of pounds of blueberries = x
Cost of one pound of strawberries = is $4
Number of pounds of strawberries = y
The equation for the all-out number of blueberries and strawberries.
6x + 4y = 36
In its most straightforward structure in algebra, the meaning of an equation is a numerical explanation that shows that two numerical expressions are equivalent. For example, 3x + 5 = 14 is an equation, where 3x + 5 and 14 are two expressions isolated by an 'equivalent' sign.

Find the volumes of the pyramid and triangular pyramid.
Answer:
1) Volume of triangular pyramid = 33 cm³.
2) Volume of triangular prism = 99 cm³
Step-by-step explanation:
1) Volume of a triangular pyramid is given as;
V_py = ⅓Ah
Where A is area of base and h is height
We see from the diagram that;
A = 11 cm²
h = 9 cm
Thus; V_py = ⅓ × 11 × 9 = 33 cm³
2) Volume of triangular prism is given by;
V_pr = ½bhl
Where;
½bh is area of triangular cross section
l is length
We see from the diagram that ½bh = 11 cm² and L = 9 cm
Thus;
V_pr = 11 × 9 = 99 cm³
4x + 3y = 1
x - 3y = -11
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 1 → (1)
x - 3y = - 11 → (2)
Adding the 2 equations term by term will eliminate the y- term
5x + 0 = - 10
5x = - 10 ( divide both sides by 5 )
x = - 2
Substitute x = - 2 into either of the 2 equations and solve for y
Substituting into (1)
4(- 2) + 3y = 1
- 8 + 3y = 1 ( add 8 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (2, - 3 )
Answer:
x=-2, y=3
Step-by-step explanation:
4x + 3y = 1.......... Equ 1
x - 3y = -11...........Equ 2
5x=-10
x=-2
From equ 1
4x + 3y =1
4(-2)+3y=1
-8+3y=1
3y=1+8
3y=9
y=3

When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor.
brainiest if you don't give sample answers
Assume that the initial coordinates are (x,y) and that the dilated coordinates are (x',y').
The dilation is therefore:
(x,y) ............> (x',y')
Now, let's assume that the dilation factor is k.
Therefore:
x' = kx
y' = ky
Based on the above, all the student has to do is get the initial coordinates and the final ones and then substitute in any of the above two equations to get the value of k.
Example:
Assume an original point at (2,4) is dilated to coordinates (4,8). Find the dilation factor.
Assume the dilation coefficient is k.
(x,y) are (2,4) and (x',y') are (4,8)
Therefore:
x' = kx .........> 4 = k*2 ..........> k = 2
or:
y' = ky ..........> 8 = k*4 .........> k = 2
Based on the above, the dilation coefficient would be 2.
Hope this helps :)
Answer:
First you have to find the ordered pairs for the shapes. Then figure out how much the pre-image was multiplied by. The number it was multiplied by is your scale value.

Answer:5
That is exactly correct! Just two things: First, tan,sin,cos, etc hold no meaning on their own, they need an argument. So just be sure to write tanx, cosx etc rather than just tan or cos.
Finally, you could save time on your proof by noticing on the fourth step that

find the first four terms of the sequence given by the following an=57-4(n-1),n=1,2,3
Answer:
57, 53, 49, 45
Step-by-step explanation:
Substitute for the n for n=1,2,3,4 so the first term is 57-4(1-1) so =57-4(0) so
a(1) = 57-0 = 57 so that is the 1st term
2nd term 57-4(2-1) so =57-4(1) so a(2) = 57-4 = 53, etc.
