I have a square piece of paper with a height of 8cm and a width of 8cm
i fold it in half to makea triangle Z
what is the area of triangle d
thanks! Will mark as brainliest
Answers
Answer:
The area of triangle is 32 cm².
Step-by-step explanation:
When you fold a square into triangle, the length of sides will still be the same. So using area of triangle formula, you are able to find the area :
[tex]area = \frac{1}{2} \times width \times height[/tex]
Let width = 8cm,
Let height = 8cm,
[tex]area = \frac{1}{2} \times 8 \times 8[/tex]
[tex]area = \frac{1}{2} \times 64[/tex]
[tex]area = 32 \: {cm}^{2} [/tex]
Given:
Height, h = 8 cmBreadth, b ( or width ) = 8 cmTo find out:
Find the area of half fold paper ( triangle) ?
Formula used:
Area of triangle = ½ × b × h
Solution:
We know that,
Area of triangle = ½ × b × h
☆ Substituting the values in the above formula,we get
Area of triangle = ½ × 8 × 8
= 4 × 8
= 32 cm²
Hence the area of given triangle is 32 cm².

Two planes are flying away from Toronto Pearson International Airport. The Air Canada
plane is flying with an average speed of 800 km/h in the direction of N30°W and the
British Airways plane is flying with an average speed of 750 km/h in the direction of
545°W. Assuming that the planes left at the same time, using different runways, how
far apart (to the nearest km) are the two planes after 90 minutes? N30°W means the angle
between north and west is 30° and 545°W the angle between south and west is 45°.
Please help ASAP!
Answers
Answer:
1832 miles
Step-by-step explanation:
First we need to find the angle between the routes of the planes.
If one is N30°W and the other is S45°W, we can find the angle between the routes with the following equation:
30 + angle + 45 = 180
angle = 105°
Then, we need to find the distance travelled by each plane, using the formula:
distance = speed * time
The time is 1.5 hours, so we have that:
distance1 = 800 * 1.5 = 1200 km
distance2 = 750 * 1.5 = 1125 km
Now, to find the distance between the planes, we can use the law of cosines:
distance^2 = 1200^2 + 1125^2 - 2*1200*1125*cos(105)
distance^2 = 3356214.43
distance = 1832 miles

The surface area is basically the area of the surface of the shape. So, if you have a cube, it’s the area of all of the surface of the cube, not anything inside.
We see that we have a net of this square pyramid. If we fold it up, the square and four triangles will make up the surface of the 3D shape we see. So, we need to find the area of all of these shapes.
SQUARE
To find the area of a square, you multiply one of the sides by itself (all the sides are the same)
10(10)=100
TRIANGLES
To find the area of a triangle, you take the base and multiply the height and then divide it by two.
10(12)=120
120/2=60
Since we have four triangles, we multiply it by four.
60(4)=240
Finally, we add this all up.
240+100=340
Therefore, the answer is 340 square inches.
I hope that this helps! Have a wonderful day!

If Andre made another countryard scale drawing at a scale of 1 to 12, would this drawing be smaller or larger than the first drawing ? Explain your reasoning.
Answers
Answer:
smaller
Step-by-step explanation:
If Andre is using a scale of 1:12 then we can safely say that the courtyard drawing will be smaller than his first drawing. This is because this scale means that for every 12 units of measurement on the original the newer version will be 1 unit of measurement. Therefore making the new drawing 12 times smaller than the first one that Andre made.

6
Answers
Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles

The measure of UW is 36 units
The measure of angles between segmentsFrom the question, a line has points U, V, W. If Point V lies between points U and W on Line segment U W, then;
UV + VW = UW
Given the following
VW = 4 x + 10.
UW = 9x – 9
UV = 2x - 4
Substitute
2x - 4 + 4x + 10 = 9x - 9
6x + 6 = 9x - 9
-3x = -15
x = 5
UW = 9x - 9
UW = 45 - 9
UW = 36 units
Hence the measure of UW is 36 units

x + 2y = -8
y= 1/2x-2
Answers
x + 2(1/2x - 2) = -8
x + x - 4 = -8
2x - 4 = -8
2x = -8 + 4
2x = -4
x = -4/2
x = -2
(-2, -3)
Explanation:
Step 1 - Multiply the second equation by two and add the two rows together
x + 2y = -8
y = 1/2x - 2
x + 2y = -8
2y - x = -4
4y = -12
Step 2 - Divide both sides of the equation by four
4y = -12
4y/ 4 = -12/ 4
y = -3
Step 3 - Substitute the negative three for y in the first equation and simplify
x + 2y = -8
x + 2(-3) = -8
x - 6 = -8
Step 4 - Add six to both sides of the equation
x - 6 = -8
x - 6 + 6 = -8 + 6
x = -2
Therefore, the ordered pair should be (-2, -3).

A house on the market was valued at $295,000. After several years, the value increased by 8%. By how much did the house's value increase in dollars? What is the current value of the house?
Answers
Answer: $23,600. ; $318,600
Step-by-step explanation:
From the question, we are informed that a house on the market was valued at $295,000 and after several years, the value increased by 8%.
The value of the increase will be 8% of $295,000. This can be mathematically written as:
= 8% of $295,000
= 8/100 × $295,000
= 0.08 × $295,000
= $23,600
The current value of the house will be:
= $295,000 + $23,600
= $318,600
