Explain how to decompose a triangle into congruent triangles. How does the area of those decomposed triangles relate to the area of the rectangle?

Answer:

y=10x

Step-by-step explanation:

The slope is 10/1 and it's positive.

Answer:

Step-by-step explanation:

angle 2 is 43 degree because angle 2 and 43 are vertically opposite angle and vertically opposite angles are always equal.

angle 1 is 137 degree because the sum of two angles in a straight line is always 180 degree.so

43+angle 1=180 degree

angle 1=180-43 degree

angle 3 is 137 degree because the relation between between angle 3 and 137 degree is vertically opposite angles and vertically opposite angles are always equal.

vertically opposite angles=e and c

complementary angle=b and c

supplementary angle=e and d

hope this helps but im probably wrong cuz im also horrible at math-

Answer:

Her trip took 2hrs 30 minutes

Step-by-step explanation:

First part: She was going 80 miles an hour and only travels 40 miles so that's 30 minutes.

Second part: she traveled 100 miles at a speed of 50 miles per hour so that's two hours.

2hrs + 30 mins

2hrs 30 mins

Answer:

33% chance

Step-by-step explanation:

well 100% divided by 1/3 which is what the 1 is split into then 100% (a circle is 100%) divided by 1/3 there's your answer :D

(really the answer is 33.333 etc. but you can just say its a 33% chance)

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Answer:

8 cm

To find the area of this square, we have to figure out what to do with given radius

Radius makes half of the square's diagonal, therefore: d=2r=32d=2r=32 mm. Now we have to find the side aa to find the area.

To find aa, use the Pythagorean Theorem.

[tex] d^{2}&=a^{2}+a^{2} \\ 32^{2}&=2a^{2}\\ 1024&=2a^{2}\\ 512\text{ mm}^{2}&=a^{2}a^{2}[/tex]

Set the equation accordingly.

Substitute for d.

You can keep a2 as we will use it in the area.

Answer:

Trapezoid i think

Answer:

14.4 inches

Step-by-step explanation:

Use the Pythagorean theorem: [tex]a^{2} + b^{2}[/tex]

So, this will be: [tex]8^{2} + 12^{2} = c^{2}[/tex]

By simplifying we get:

c = [tex]\sqrt{208}[/tex]

The missing side is: 14.4 (rounded to the tenth)

Answer:

[tex] \displaystyle 4 \sqrt{13}in [/tex]

Step-by-step explanation:

we are given a right angle triangle and we want to figure out the missing hypotenuse in order to do so we can consider using Pythagoras theorem given by

[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] \displaystyle \implies{c}^{} = \sqrt{ {a }^{2} + {b}^{2} } [/tex]

let a and b be 8 and 12 respectively thus

substitute:

[tex] \displaystyle {c}^{} = \sqrt{ {8 }^{2} + {12}^{2} } [/tex]

simplify squares:

[tex] \displaystyle {c}^{} = \sqrt{ 64 + 14 4} [/tex]

simplify addition:

[tex] \displaystyle {c}^{} = \sqrt{208} [/tex]

by simplifying the redical expression we obtain:

[tex] \displaystyle {c}^{} = 4 \sqrt{13} [/tex]

Answer:

1/3

Step-by-step explanation:

Second Spin: There are 4 but I have only 1 = 1/4

Answer:

i would go with either c or d. this is a very confusing question. im sorry if im wrong. good luck though

Step-by-step explanation:

Answer:

c)

Step-by-step explanation:

Minimum value (first dot), lower quartile (where the box starts) , median (a lin e in the middle of the box) , upper quartile(Where the box ends)  and the maximum value(Final dot).

25 , 29 , 32 , 35 , 38

Your data set should contain these data's.So, C is the answer

Answer:

x= 29 degrees,  y= 61 degrees

Step-by-step explanation:

Complementary angles and up to 90 degrees, . Sif half of 90 is 45 and y is 16 more than x,  you just need to add 16 to y and subtract 16 from x.

Answer:

Paper Lanterns: 4

Bags of Balloons: 12

Garlands: 11

Banners: 4

Step-by-step explanation:

Cost of lanterns is $6.50

Mrs. Murphy bought 4 lanterns

Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)

6.50 multiplied by 4 equals 26

Cost of banners is $5.25

Mrs. Murphy bought 4 banners

Multiply the cost of one banner ($5.25) by the number of banners bought (4)

5.25 multiplied by 4 equals 21

Mrs. Murphy bought 3 times as many balloons as she did lanterns

So, you multiply the number of lanterns bought (4) by 3

This gives you 12

You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)

5.00 multiplied by 12 equals 60

Mrs. Murphy bought 7 more garlands as she did lanterns

So, you add 7 to the number of lanterns bought (4)

7 plus 4 equals 11

To find the cost of the total garlands bought

You multiply the cost of each garland ($3.50) by the number of garlands bought (11)

3.50 multiplied by 11 equals 38.5

Now you can add up the costs of all the items

26+21+60+38.5=145.50

145.50 was the total amount she spent so you know it is the correct answer.
