at a) paint the figure horizontal on the right side. P becomes P´

b) paint the figure A one step clochwise arround P. 60° is one angle of the triangles. All angles in a triangle are together 180°. so we have 3 angles with same size so 180°/3=60°

c) go two triangles to the left and paint the same figure A as on the left side of l.

Answer:

Given below

Step-by-step explanation:

M is Mikey and B is Betty in,

Current ages:

M= x

B= 3x (cuz she is 3 times older)

After 5 years

M= x+5

B= 3x+5 (5 years added to present age)

It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))

So,

3x+5 = 2(x+5)

3x+5 = 2x+10

3x -2x = 10-5

x = 5

Therefore,

The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

The length of a rectangle is four times the width minus three. If the perimeter of the rectangle is 64 meters, what is the lengt

Nastasia [14]

Answer:

L = 25 m

Step-by-step explanation:

L = 4W - 3

perimeter = 2(L + W)

64 = 2(4W - 3 + W)

divide both sides by 2:

32 = 5W - 3

add 3 to each side:

5W = 35

divide both sides by 5:

W =7

L = 4(7) - 3 = 25

Tina is joining 3 sections of a quilt. Each section has 3 rows of 15 square pieces of fabric. How many squares will be in the co

Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

$3\times 3\times 15\\\\=9\times 15\\\\=135$

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Which pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number?

laiz [17]

Answer:

Option C, D, E

Step-by-step explanation:

To find : Which pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number?

Solution :

We divide large number by smaller number to get the required answer,

A) $\frac{2.01\times 10^7}{4.25\times 10^6}=4.7294\approx 4$

B) $\frac{5.97\times 10^4}{3.12\times 10^3}=19.1346153846\approx 19$

C) $\frac{4.91\times 10^6}{5.09\times 10^3}=9365.4033\approx 9365$

D) $\frac{8.21\times 10^{-3}}{4.13\times 10^{-4}}=19.8789\approx 20$

E) $\frac{6.22 \times 10^{-7}}{2.94\times 10^{-8}}=21.156462585\approx 21$

Option C, D and E pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number.
