Mai and Tyler work on the equation 2 5 b + 1 = - 11 together. Mai's solution is b = - 25 and Tyler's is b = - 28 . Here is their work:


Mai:

2 5 b + 1 = - 11

2 5 b = - 10

b = - 10 ⋅ 5 2

b = - 25


Tyler:

2 5 b + 1 = - 11

2 b + 1 = - 55

2 b = - 56

b = - 28


Do you agree with their solutions? Explain or show your reasoning.

Answers

Answer 1

Answer:

I do not agree with the solutions, b=-30, reasoning below.

Step-by-step explanation:

Mai made an error between the first and second line, she added one to the right when she should have subtracted one:

2/5b+1=-11

2/5b=-12

She then multiplied by 5/2 which was correct, however she multiplied it by -10 when it should have been -12:

b=-12*5/2

b=-30

Tyler made an error between the first and second line when he did not multiply the 1 on the left by 5 also:

2/5b+1=-11

2b+5=-55

He did the next steps correctly, however he had the incorrect value, it should look like this:

2b=-60

b=-30

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 1225 hours and also earned some tips. Her final pay for the week was $159.50.
How much money did Yolanda earn in tips?

Answers

Answer:

she earned $20 in tips

Step-by-step explanation:

- figure out how much she'll get payed in 12 hours of work, :

12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

now you need to subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20, so basically thats how i got 20.

use the zero and the labeled point to write the quadratic function represented by the graph.

A.y=x^2-2x-8

B. y=2x^2-12x+16

C. y=x^2+2x-8

D. y=2x^2+4x-16

Answers

Answer:

A. x² - 2x - 8

Step-by-step explanation:

At x = -2, 4 graph cut x- axis. So, they are zeroes of f(x).

So, f(x) = k(x+2)(x-4), where k is a constant.

Now, (3, -5) in f(x), we get

-5 = k (3+2)( 3 -4)

-5 = -5k

k= 1

So, f(x) =  (x+2)(x-4)

= x² - 2x - 8

So, option A is right.

Answer:

A die has 6 numbers.

So 6 numbers them being

State and show what additional information is required in order to know that the triangles are
congruent for the given reason.
SAS

Answers

Answer:

Step-by-step explanation:

We already know that both triangles have a congruent side length.

We also know angle KVM or UVW are the same

We only have to know if VM and WV are the same.

This way, each triangle will have two congruent side lengths and a angle. The third side will therefore be the same.

By the same logic, if we know that KM and UW are the same, the two triangles are also congruent.

To determine if two triangles are congruent using the SAS (Side-Angle-Side) criterion, we need additional information about the length of one side, the measure of one angle, and the length of another side in both triangles.

This information is crucial in order to establish the congruence between the triangles. For example, let's consider two triangles, triangle ABC and triangle DEF. To prove that these triangles are congruent using the SAS criterion, we need to know: 1. The length of side AB in triangle ABC and the length of side DE in triangle DEF. 2. The measure of angle A in triangle ABC and the measure of angle D in triangle DEF. 3. The length of side BC in triangle ABC and the length of side EF in triangle DEF. By knowing these measurements, we can compare the corresponding sides and angles of the two triangles. If the lengths of the corresponding sides are equal and the measures of the corresponding angles are equal, then we can conclude that the two triangles are congruent by the SAS criterion.

In the year 2003, a company made $6.5 million in profit. For each consecutive year after that, their profit increased by 8%. How much would the company's profit be in the year 2007, to the nearest tenth of a million dollars?

Answers

Answer:

$8,580,000 (rounded) = $9,000,000

Step-by-step explanation:

Keep in mind, 2007 is four years after 2003.

So, 8(%) • 4 = 32(%)

Over the course of 4 years, the companies profits increased by a total of 32 percent.

(*Write 6.5m in standard form)

6,500,000 + 32% = $8,580,000

8,580,000 (rounded up) = 9,000,000

Answers

Answer:

length = 50 cm

Step-by-step explanation:

let width be w then length = w + 10

area = w(w + 10) = 2000 , that is

w² + 10w = 2000 ( subtract 2000 from both sides )

w² + 10w - 2000 = 0 ← in standard form

Consider the factors of the constant term (- 2000 ) which sum to give the coefficient of the w- term ( + 10)

the factors are + 50 and - 40 , since

50 × - 40 = - 2000 and sum = 50 - 40 = + 10

(w + 50)(w - 40) = 0 ← in factored form

equate each factor to zero and solve for w

w + 50 = 0 ⇒ w = - 50

w - 40 = 0 ⇒ w = 40

Since w > 0 then w = 40 and

length = w + 10 = 40 + 10 = 50 cm
