The supply paper comes in sheets that are one 130 cm x 220 cm how many envelopes can accompany make from each sheet of paper
Answers
This question is incomplete, the complete question is;
An envelope company has redesigned their large envelopes.
The new designs is shown below; The missing diagram of the envelope is uploaded along this answer below.
a) Determine the area of the envelope
b) The supply paper comes in sheets that are one 130 cm x 220 cm how many envelopes can accompany make from each sheet of paper
Answer:
a) Area of the envelope is 1450 cm²
b) The company can make 19 envelopes from each of the sheet paper.
Step-by-step explanation:
Given the data in the question,
From the diagram of the envelope below;
it can be divided into 3 part
First part is the Triangle, Middle part is a rectangle and the last part is a smaller rectangle.
From the image;
First Part
Base of the Triangle is 30 cm while the height is 14 cm
so Area Of the Triangle = [tex]\frac{1}{2}[/tex] × base × height
= [tex]\frac{1}{2}[/tex] × 30 cm × 14 cm = 210 cm²
Middle Part;
Length of the middle Rectangle = 20 cm
while the breadth = ( 30cm + 1 cm + 1 cm ) = 32 cm
So Area of the Middle Rectangle = Length × Breadth
= 20 cm × 32 cm = 640 cm²
Last part;
Length of the Rectangle = 20 cm
while the breadth = 30cm
So Area of the Last Rectangle = Length × Breadth
= 20 cm × 30 cm = 600 cm²
∵ Total AREA = 210 cm² + 640 cm² + 600 cm² = 1450 cm²
Therefore, the area of the envelope is 1450 cm²
b)
given that; supply paper comes in sheets that are 130 cm by 220 cm,
how many envelopes can accompany make from each sheet of paper.
Number of enveloped that can be made = Area of Supply paper / Area of envelope
N = ( 130 cm × 220 cm ) / 1450 cm²
N = 28600 cm² / 1450 cm²
N = 19.724 ≈ 19 { We round down, else the supply paper wont be enough }
Therefore, The company can make 19 envelopes from each of the sheet paper.

Rebecca paid $16.90 to place an advertisement in a local
newspaper. The newspaper charged $4.50 set up fee and $0.40
per word. How many words were in Rebecca's advertisement?
Answers
12.40/0.4 = 31 words in the ad
Answer:
31 words
Step-by-step explanation:
because the set up fee is 4:50$, minus this from the price Rebecca payed
16.90-4.50=$12.40
now divide this amount by $0.40 in order to get her word count
12.40÷0.40=31
The sides of a triangle are 3 consecutive odd integers and the shortest side is 20% of the perimeter of the triangle. What is the perimeter of the triangle?
Answers
Answer:
15 units
Step-by-step explanation:
The terms of an odd integer are given by 2n - 1. Since the sides of the triangle are three consecutive odd integers, let them be 2n - 1, 2(n + 1) - 1 and 2(n + 2) - 1 respectively, where 2n - 1 is the shortest side
Let P = perimeter of triangle = 2n - 1 + 2(n + 1) - 1 + 2(n + 2) - 1
= 2n - 1 + 2n + 2 - 1 + 2n + 4 - 1
= 2n - 1 + 2n + 1 + 2n + 3
= 2n + 2n + 2n - 1 + 1 + 3
= 6n + 3
Since the shortest side is 20% of the perimeter of the triangle, we have that
2n - 1 = 20%(6n + 3)
2n - 1 = 0.2(6n + 3)
expanding the bracket, we have
2n - 1 = 1.2n + 0.6
subtracting -1.2n and adding +1 to both sides, we have
2n - 1.2n = 1 + 0.6
0.8n = 1.6
dividing both sides by 0.8, we have
n = 1.6/0.8
n = 2
Since P = 6n + 3, substituting n = 2, we have
P = 6(2) + 3 = 12 + 3 = 15 units

PLEASE HELP ME IF YOU CAN! please tell me how you got the answer thank you!
Answers
You can either use Pythagorean theorem or special triangle proportions to find the side that is parallel to z. Since in a 45-45-90 degree triangle, the hypotenuse is the leg times the square root of 2, and the hypotenuse is 3, we know that the leg is 3/sqrt(2) which is equal to 3 sqrt(2) / 2. Since z is twice this length, we know that z is equal to 2 x 3sqrt(2)/2 = 3sqrt(2)

We start by making a factorization of the first expression
By using the difference of two squares, we can have it as;
a^2 - b^2 = (a + b)(a-b)
For the second expression, we already have;
(a + b)^2 = (a + b)(a + b)
What this mean is that (a + b) is common to both expressions and we have it as the highest common factor

Please help me A line that includes the point (3, 3) has a slope of 4. What
is its equation in slope-intercept form?
Answers
Answer:You can do this two ways: Either use the slope intercept form
y = mx + b with slope m=-2 so y = -2x +b
From that use x=5, y = -3 to solve for b
-3 = -2(5) + b
-3 = -10 + b
10-3 = b
7 = b
Your equation is: y = -2x + 7
OR
Use the point slope formula: y - y1 = m(x-x1)
with m = -2, (x1, y1) = (5,-3)
y-(-3) = -2(x-5)
y + 3 = -2x + 10
y = -2x + 10 - 3
y = -2x + 7

= p
f(2.5) = 3(2.5) - 2(2.5)^2 = q

= q
b) graphing
c) From the graph, you should be able to verify the following:

Lupe needs to make a poster that is 2 m by 4 m for the big game. The cost of the paper is $1.75. Later she needs another poster with dimensions 1 m by 2 m. What is the paper for this poster likely to cost
Answers
Answer:
$0.42
Step-by-step explanation:
Given data
Dimension
Length=4m
Width=2m
Cost= $1.75
Area= 4*2= 8m^2
Cost per area=1.75/8
Cost per area=$0.21 per m^2
The new poster's dimension
Lenght =2m
Width= 1m
Area= 2*1= 2m^2
Hence if a square meter cost $0.21
Then 2 square meter will cost x
cross multiply
2*0.21=x
x=$0.42
Hence the new poster will cost $0.42

Hello! answer: 45 and 45 is a complementary angle and 60 and 30 is a complementary angle
Step-by-step explanation:
Complementary angles are just angles that add up to 90 degrees so... 45 + 45 = 90 60 + 30 = 90 so that is how those are complementary angles.
Hope that helps!
Answer:
angle QRT/angle VRT and angle SRW/angle WRV
Step-by-step explanation:
QRT and VRT: Both angles are 45 degrees, adding those degrees together gets you 90 degree angles meaning that they are complementary.
SRW and WRV: 60 plus 30 is equal to 90 making them complementary angles as right angles are 90 degrees
