Answer:

Step-by-step explanation:

-x +8y = 4

8y = x+4

y = x/8 + 1/2

y= mx +b

where b is the y-intercept

y- intercept is 1/2

x/8 +1/2 = 0

x/8 = -1/2

2x = -1*8

x = -8/2 = -4

x- intercept is -4

Answer:

Concept: Numerical Analysis

Answer:

1/50 as far

Step-by-step explanation:

6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]

Rules state that you divide numbers and subtract exponents

6.8/3.4 = 2

10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]

whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator

10^-2 = 1/10^2 which is the same as 1/100

2 multiplied by 1/100 = 1/50

Answer:

D

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 = 7x - 10 ← is in slope- intercept form

with slope m = 7

Parallel lines have equal slopes, thus

m = 7 and point on line is T(- 3, 3 )

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line, then

y - 3 = 7(x - (- 3) ), that is

y - 3 = 7(x + 3) → D

Answer:

First option y=3/5x

Step-by-step explanation:

Because if you look on the graph, at x=5, y=3

in the equation, plug in x=5, you cancel out denominator left with y=3

Answer:

$12500

Step-by-step explanation:

Given that:

Salary plan 1:

Weekly salary of $500.

And a commission of 4%.

Salary plan 2:

Straight commission of 8%.

To find:

Weekly sales for which both the plans will make the same sales?

Solution:

Let the weekly sales = $[tex]x[/tex]

As per question statement:

Salary as per Plan 1 = $500 + 4% of [tex]x[/tex]

Salary as per Plan 2 = 8% of [tex]x[/tex]

Putting both the salaries to equal to find the total weekly sales.

$500 + 4% of [tex]x[/tex] = 8% of [tex]x[/tex]

[tex]\Rightarrow 500 = 4\%\ of\ x\\\Rightarrow 500 = \dfrac{4}{100}x\\\Rightarrow x = \$12500[/tex]

Therefore, the answer is:

For the sales of $12500, the salary will be same from both the plans.

Ratio who signed other club:

4/5

Step-by-step explanation:

First find out ratio who signed up for art club

you have 16 out of 80

find the common factor: 16

16/16 = 1

80/16 = 5

so 1/5

other clubs is the rest so 5/5 - 1/5 = 4/5

Answer:

Solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

Step-by-step explanation:

We need to solve the equation [tex]15 = 3n + 6p[/tex] for variable n

Solving:

[tex]15 = 3n + 6p[/tex]

Subtract both sides by 6p

[tex]15-6p = 3n +6p -6p\\15-6p=3n[/tex]

Switch sides of equality

[tex]3n=15-6p[/tex]

Divide both sides by 3

[tex]\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p[/tex]

So, solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

Answer:

4.11 cups of skim milk

Step-by-step explanation:

You can get the answer by knowing the value of a cup in milliliters first.

Let's convert 3.58 cups to ml by using the multiplication operation.

895 ml is 87% of skim milk.

Let's convert this into an equation. Let x be the amount of skim milk.

895 = 87% of x

895 = 0.87(x)

x = [tex]\frac{895}{0.87}[/tex]

x = 1,028.73 ml

Now that we know the amount of skim milk, let's convert it to cups.

1,028.73 ml ÷ 250 ml = 4.11 cups

Let's check.

4.11 cups of skim milk contain 3.58 cups of water.

Given,

Skim milk contain water is 87% of water = 0.87

We have to find ,

Total no. of Cups of skim of milk 3.58 cups of water.

According to the question .

The value of a cup in milliliters first.

We know that ,

1 cup = 250 ml  

Let's convert 3.58 cups to ml  

3.58 x 250 = 895 ml

895 ml is 87% of skim milk.

Let's convert this into an equation. Let x be the amount of skim milk.

895 = 87% of x

895 = 0.87(x)

[tex]x = \frac{895}{0.87}[/tex]

x = 1,028.73 ml

To know the amount of skim milk, let's convert it to cups.

1,028.73 ml ÷ 250 ml = 4.11 cups

Answer:

A is 30 degrees.

Step-by-step explanation:

cot A = 1/ tan A

Therefore 3 tan A = 1 / tan A

3 tan^2 A = 1

tan^2 A = 1/3

tan A = 1 /√3   is A is acute.

A = 30 degrees.

This is about trigonometric identities.

A = 30°

Tan A = sin A/cos A

Cosec A = 1/sin A

Sec A = 1/cos A

Cot A = 1/tan A

3 tan A = cot A

But we know from above that Cot A = 1/tan A

Thus;

3 tan A = 1/tan A

Rearranging to get;

(tan A)² = 1/3

tan A = √(1/3)

tan A = 1/√3

sin 30° = cos 60° = 1/2

sin 60° = cos 60° = (√3)/2

sin 45° = cos 45° = 1/√2

tan 30° = 1/√3

tan 60° = √3

tan 45° = 1

A = 30°

A is said to be an acute angle which means it is less than 90° and so it is correct.
