Answer:

x = number of pairs of sandals sold = 287

Total pair of sneakers and sandals sold = 451 pairs

Step-by-step explanation:

Sneakers = 4

Sandals = 7

Sneakers : sandals = 4 : 7

If the store sells 164 pair of sneakers

Let

x = number of pairs of sandals sold

Sneakers : sandals = 164 : x

Equate both ratios to find x

4 : 7 = 164 : x

4/7 = 164/x

4 * x = 7 * 164

4x = 1,148

x = 1,148/4

x = 287

x = number of pairs of sandals sold = 287

how many pair of sneakers and sandals does the store sell in all ?

Total pair of sneakers and sandals sold = Sneakers + sandals

= 164 + 287

= 451 pairs

Total pair of sneakers and sandals sold = 451 pairs

Answer:

Step-by-step explanation:

The rectangle ABCD has vertices A(-2,2), B(6,2), C(6,3) and D(-2,3).

Now, length of side AB = [6 - (- 2)] = 8 units.

{Since the line AB is parallel to the x-axis, so the length of the segment AB will be the difference between the x-coordinates of the points A and B}

Again, line BC is parallel to y-axis and hence the length BC = (3 - 2) = 1 units.

Therefore, the area of the rectangle ABCD will be (8 × 1) = 8 sq. units. (Answer)

Answer:

Its A

Step-by-step explanation:

I took the quiz.

The total number of different ways he can get from Town A to Town D is

60 ways , Option A is the correct answer.

The way of selecting objects from a group of objects such that the order does not matter.

It is given that

There are 3 ways to get from Town A to Town B

The total number of ways he can select one route is ³C₁ = 3

There are 4 ways to get from Town B to Town C

The total number of ways he can select one route is ⁴C₁ = 4

There are 5 ways to get from Town C to Town D

The total number of ways he can select one route is ⁵C₁ = 5

The total number of different ways he can get from Town A to Town D is

3 * 4 * 5

= 60 ways

Therefore Option A is the correct answer.

Answer:

x = [tex]\sqrt{14}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in both tight triangles.

First in the small triangle to find the third side ( hypotenuse ) h

h² = 1² + 1² = 1 + 1 = 2 ( take square root of both sides )

h = [tex]\sqrt{2}[/tex]

Now use the identity in the larger right triangle

x² + h² = 4²

x² + ([tex]\sqrt{2}[/tex] )² = 16

x² + 2 = 16 ( subtract 2 from both sides )

x² = 14 ( take square root of both sides )

x = [tex]\sqrt{14}[/tex]

Step-by-step explanation:

x > 4 hours/week

4 hours is 240 minutes

45 minutes/ 1st book

4 hours minus 45 minutes is 3 hours and 15 minutes

3 hours and 15 minutes = 195 minutes

195 minutes ÷ 6 = 32.5 minutes

make the formula working backwards

(240 - 45) ÷ 6 > x

Answer:

Elsa sent 15, Lamar sent 30, and Keith sent 23

Step-by-step explanation:

If x=Elsa, L=Lamar, and K=Keith

2x=L

x+8=K

x+x+8+2x= 68

4x+8=68

4x=60

x=15

Then you plug 15 into x, and solve for each person.

(15)2=L

(15)+8=K

Step-by-step explanation:

Answer:

a. Firat term of the sequence= 77

b. 29th term of the sequence= -35

c. Sum of the first 40 terms of the sequence= -40

Step-by-step explanation:

The first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.

Given that, [tex]a_{15} =21[/tex] and d=-4.

The nth term of the arithmetic sequence is [tex]a_{n} =a+(n-1)d[/tex].

To find the first term of the sequence:

[tex]a_{15}[/tex]=a+(15-1)(-4)

⇒21=a+(15-1)(-4)

⇒a=77

To find the 29th term of the sequence:

[tex]a_{29}[/tex]=77+(29-1)(-4)=-35

To find the sum of the first 40 terms of the sequence:

The first n terms of a sequence [tex]=\frac{n}{2}[2a+(n-1)d)][/tex]

[tex]S_{40} =\frac{40}{2}[2 \times77+(40-1)(-4))][/tex]

=20(154-156)=-40

Therefore, the first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.

Given :-

To Find :-

We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,

[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]

[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]

Hence the slope of the line is 27/11 .

[tex]\rule{200}2[/tex]

Finding the length of AB :-

[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]

Hence the length of AB is 29.15 units .
