Durning the summer , a shoe store sells sneakers and sandals at a ratio of 4:7 . If the store sells 164 pair of sneakers, how many pair of sneakers and sandals does the store sell in all ?

Answers

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

What is the area of rectangle ABCDABCDA, B, C, D? Please Help

Answers

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)

The 15th term of an arithmetic sequence is 21 and the common difference is -4.

(b) Find the 29th term of the sequence.
(c) Find the sum of the first 40 terms of the sequence.

Answers

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.

What is the nth term of the arithmetic sequence?

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.

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..

A) the slope of the line AB

B) The length of the line AB

Answers

Answer:

Slope = 27/11AB = 29.15 u

Step-by-step explanation:

Given :-

Two points are given to us .The points are A(7,15) and B(18,42)

To Find :-

The slope of the line .The length of line AB .

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]

Plug in the respective values ,

[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 :-

We can find the distance between them by using the Distance Formula .

[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 .

Brice had a number of ethical issues come up in law school involving alleged cheating but managed to graduate because nothing was ever proven. Upon obtaining his law license, Brice enjoyed living "on the edge" and engaged in tactics that were at least questionable. One of his clients was an older gentleman, Sam, with significant assets and significant legal issues involving a messy divorce stemming from his involvement with a local dog groomer, Susie. Brice told Sam that he felt certain that he could arrange matters so that Sam could live happily in the Caribbean with Susie but that, in addition to paying a hefty legal fee, Sam would need to name Brice as a significant beneficiary in his will and give Brice power of attorney over his assets. Sam agreed to do so. He gave Brice power of attorney and changed his will to reflect that upon his death, Brice would receive half his estate. The other half went to Susie. Sam also paid the hefty legal fee Brice demanded. At that point, Brice agreed to proceed with negotiations in the divorce. Shortly after the divorce, Sam had an unexpected heart attack and died immediately. Susie, the executor of the will, told Brice that she was reporting him to the state bar association and that he was not entitled to any assets from the estate. Brice told Susie that he knew that Susie had failed to pay income tax for all her dog grooming and that he was reporting her unless she kept her mouth shut and consented to the terms of the contract. Brice also said that in return for keeping his mouth shut, he wanted additional sums purportedly for his work on Sam's divorce. Assuming that Sam had paid all amounts validly due from the divorce proceeding, which of the following is true regarding Brice's attempt to obtain additional fees? A. Brice has caused Susie to experience duress. B. Brice has unduly influenced Susie. C. Brice has caused Susie to experience duress and unduly influenced Susie. D. Brice has committed intentional wrongful disclosure. E. Brice is not guilty of anything, so long as he used no physical force to obtain Susie's agreement. What is the area of the triangle??
