Answer:

1) b-x/a

Step-by-step explanation:

Answer:

Option 1

Step-by-step explanation:

x + ay = b

Subtract x from both sides;

ay = b - x

Divide both sides by a;

y = [tex]\frac{b-x}{a}[/tex]

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.

Answer:

x = -1

Step-by-step explanation:

-2+3x=-(x+6) distrbute the negative

-2+3x=-x-6 combine liked terms (added x & 2 to each side)

+2 +x   +x  +2

4x = -4 isolate x (divide 4 from each side)

x = -1

Answer:

X=-1

Step-by-step explanation:

First, add 2 on both sides to eliminate -2 and to get 3x alone. Now you have the product of 3x=-x-4. Next, add x on both sides to isolate negative 4. Once, you have done this you get 4x=-4. Now you divide by 4 to get x alone. And you get the product x= -1.

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.

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:

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:

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:

3 whole pizzas required.

Step-by-step explanation:

Given that:

Total number of friends invited by Bob = 11

Total number of people on the birthday party = 11 friends + 1 Bob himself = 12

Each friend has eaten = 2 pieces of pizza

Number of slices in one whole pizza = 8

To find:

Number of whole pizzas required at the birthday party.

Solution:

First of all, let us find the number of slices required for the birthday party.

Number of slices of pizza required for the birthday party = Number of slices eaten by each person multiplied by number of persons at party.

Number of slices of pizza required for the birthday party = 12 [tex]\times[/tex] 2 = 24

Now, let us divide the total number of slices with the number of slices in one whole pizza to find the total number of whole pizzas required for the party.

Number of whole pizzas required:

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
