Answer:

12.9 - 22.7b

Step-by-step explanation

Given the expression 4.3(3-5b) = 1.2b

Open the bracket

4.3(3-5b) = 1.2b

4.3(3)-(4.3)(5b) = 1.2b

12.9 - 21.5b = 1.2b

12.9  - 21.5b - 1.2b

12.9 - (21.5+1.2)b

12.9 - 22.7b

Hence the required expression is 12.9 - 22.7b

A team's total salaries is $4,614,244. The team would like to bring the total down to $3.5 million. What would be the percentage decrease in the team's total salary?

Answers

Answer:

24.14%

Step-by-step explanation:

Given that,

A team's total salaries is $4,614,244.

The team would like to bring the total down to $3.5 million = $3500000

We need to find the percentage decrease in the team's total salary. The percentage decrease/increase in any value is givenby :

[tex]\%=\dfrac{\text{change in population}}{\text{initial population}}\times 100\\\\=\dfrac{3500000-4,614,244}{4,614,244}\times 100\\\\=24.14\%[/tex]

So, the percentage decrease in the team's total salary is 24.14%.

While on vacation in Bloomington, Ashley went out for a dinner that cost $20. If sales tax in Bloomington is 10% and Ashley left a 15% tip on $20, what was the total cost of her meal?

Answers

Answer:

$25

Step-by-step explanation:

Given that:

Cost of Ashley's dinner in Bloomington = $20

Sales tax = 10%

Tip = 15% on $20

To find:

Total cost of the meal ?

Solution:

Let us find the sales tax first of all.

Sales tax is 10% of the total bill.

Therefore, sales tax = 10% of $20

[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]

Tip left is 15% of the total bill.

Therefore, tip = 15% of $20

[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]

Now, total cost of the meal = Food cost + Sales tax + tip

Total cost of the meal = $20 + $2 + $3 = $25

Write an equation of the line that passes through (2,-1) and is parallel to the line y=-3x+8

Answers

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 8 ← is in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, then

y = - 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 6 + c ⇒ c = - 1 + 6 = 5

y = - 3x + 5 ← equation of line

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -2 + x = -x + 2

Then the value of x will be,

→ -2 + x = -x + 2

→ x + x = 2 + 2

→ 2x = 4

→ x = 4 ÷ 2

→ [ x = 2 ]

Hence, the value of x is 2.

Answers

Answer:

1. Second Choice

2. Positive

3. Line B

4. Line D

5. Horizontal

Step-by-step explanation:

First Screenshot

The y-intercept is the value of b —

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.

Basically (0,a) is y-intercept.

Thus, our y-intercept is (0,1)

Second Screenshot

The slope is positive. If the slope is negative, it would face opposite.

For zero slope, the graph will become a horizontal line.

An undefined slope is the vertical line graph.

Third Screenshot

Line B has zero slope. As said, the zero slope will turn the graph into a horizontal line.

Fourth Screenshot

Line D has an undefined slope. Read Third Screenshot.

As said, an undefined slope is the vertical line.

Fifth Screenshot

[tex]y = - 3[/tex]

This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)

FYI,

y = a — horizontal

x = a — vertical

Answers

Answer:

Step-by-step explanation:

X is less than 10 because you have the plus in the equation and so it as to be less than ten so that when you multiply it by 10 it equals less than 100. I don’t know if my explanation makes sense but I hope it helps.

Answers

Answer:

Step-by-step explanation:

For a moving object, the force acting on the object varies directly with the object's acceleration.

F ∝ a

or

[tex]\dfrac{F_1}{a_1}=\dfrac{F_1}{a_2}[/tex]

Put F₁ = 8 N, a₁ = 4 m/s², F₂ = 18 N and a₂ = ?

Put all the values,

[tex]\dfrac{8}{4}=\dfrac{18}{a_2}\\\\2=\dfrac{18}{a_2}\\\\a_2=9\ m/s^2[/tex]

So, the new acceleration is [tex]9\ m/s^2[/tex].

use the quotient rule to find the derrivatives of 3/x^2​

Answers

Answer:

f'(x) = -6/x³

Step-by-step explanation:

We are given;

f(x) = 3/x²

Using quotient rule, we can write as;

f(x) = g(x)/h(x)

To find the derivative, from quotient rule, we can write;

f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²

g'(x) = 0

h'(x) = 2x

Thus;

f'(x) = [(x²*0) - (3*2x)]/(x²)²

f'(x) = -6x/x⁴ = -6/x³

f'(x) = -6/x³

m∠NPM = 101

Answer:

<NPM = 101°

Step-by-step explanation:

<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)

<NPM = 180° - 79°
