Answer:

its the last one

400 x ( 3+5) / 1

Answer: B 43

Step-by-step explanation:

Well for a triangle it has to be equal to 180 so you would add 75 and 62 to get 137 so you would add each answer to 137 and whichever one equals 180 is the answer therefor stating that the answer is B 43.

Answer:

Left triangle is scalene, middle is equalaterial, right is isosolece.

Step-by-step explanation:

Scalene traingles have three different angles, and no sides are the same. Equalateral on the other hand have all congruent (equal) angles, and isosolece triangles have two equal sides and two equal angles.

Answer:

new dimentions = 12, 12, 24, 24

new perameter  = 72cm

new perameter will be 4 times as large as the original

Step-by-step explanation:

2(3*4) + 2(6*4) = 24+48 = 72

72/4 = 18

The new rectangle would have the dimensions 12 cm and 24 cm

The perimeter of the new rectangle would be 72 cm

And, The new perimeter will be 4 times as large as the perimeter of the original rectangle .

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The perimeter of rectangle is,

⇒ P = 2(3) + 2(6) = 18 cm.

Now, After multiplied by 4 in all the dimensions we get;

Dimensions are,

⇒ 4 × 3 = 12

⇒ 4 × 6 = 24

Hence, The perimeter of the new rectangle would be;

⇒ 2 (12 + 24)

⇒ 2 × 36

⇒ 72 cm

⇒ 18 × 4 cm

Thus, The perimeter of the new rectangle would be 72 cm

And, The new perimeter will be 4 times as large as the perimeter of the original rectangle .

Step-by-step explanation:

easy no promble at alll

The number sequence follows the rule multiply by 3, starting from 4 are 4, 12, 36, 108, 324. That is option C.

The rule multiple by any number is the sequence of number that are arranged in such a form that the next number to an integer is times the particular given number of the multiple.

From the question,

4 × 3 = 12

12 × 3 = 36

36 × 3 = 108

108× 3 = 324

Therefore, the number sequence follows the rule multiply by 3, starting from 4 are 4, 12, 36, 108, 324.

Step-by-step explanation:

Vertical rectangle:

A = bh

A = (5)(10)

A = 50

Horizontal rectangle:

h = 4

A = bh

A = (8)(4)

A = 32

Combined:

Step-by-step explanation:

Answer:

The width is 12 feet.

Step-by-step explanation:

If you divide 1,680 by 14 it will give you 120 then divide that by 10 it will give you 12 ft.

Answer:

34%

n = new % = Answer

(4kg x 16%) + (12kg x 40%) = (New Percentage(Total kg))
(.16 x 4) + (.4 x 12) = n(4 + 12)

Simplify above to get:

.64 + 4.8 = 16n
.64 + 4.8 = 5.44
5.44 = 16n
Divide both sides by 16
.34 = n
34%
Convert .34 to Percentage by moving decimal to the right 2 times.

Step-by-step explanation:

1. Image of A is, A' (-7,-2)

2. Pre image of B' is, B (6,6)

3. Image of C is, C' (-3,-5)

4. The side which is congruent to side AB is, A'B'

5. The angle that is congruent to angle C is C'

6. The translation is 9 units left and 6 units down, so (x,y) becomes (x',y') where x' = (x-9) and y' = (y-6)

7.

a. The translation is 2 units right and 8 units down,

so, P (x,y) to P' (x+2,y-8)

b. Quadrilateral PQRS becomes P'Q'R'S' where the translation is 2 units right and 8 units down. Both quadrilateral are same in shape, length and size, their co-ordinates are different, their co-ordinates translated as follows,

P (-4,5) to P' (-2,-3)

Q (0,5) to Q' (2,-3)

R (2,1) to R' (4,-7)

S (-4,1) to S' (-6,-7)

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm
