Answer:

3.3 x 10^-4

Step-by-step explanation:

It's 3.3 x 10^-4 because 3.3 x 10^-4 would be 0.00033 and 8.0 x 10^0 would be 1 so 0.00033 x 1 = 0.00033. Then when we plug 0.00033 into scientific notation we will get 3.3 x 10^-4

Answer:

73°

Step-by-step explanation:

To find ∠QPS, just add ∠1 and∠2

∠QPS = ∠1 + ∠2

          = 44° + 29°

          = 73°

Answer:

∠QPS = 73°

Step-by-step explanation:

∠1 = 44°

∠2 = 29°

∠QPS = ∠1 + ∠2 = 44° + 29° = 73°

Answer: [tex]y=12.50x[/tex]

Step-by-step explanation:

Let the number of hours be x and the total earnings in dollars be y. Since the total amount of money earned is the number of hours times the amount earned per hour, the equation is [tex]y=12.50x[/tex].

The function table should be completed as follows:

x                h(x)__

-4               -8

-3               -5

2                 10

4                 16

5                 19

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.

Next, we would evaluate the given function by substituting the value of x as follows:

When x = -4, we have:

Function, h(x) = 3x + 4

Function, h(-4) = 3(-4) + 4

Function, h(-4) = -12 + 4

Function, h(-4) = -8

When x = -3, we have:

Function, h(x) = 3x + 4

Function, h(-3) = 3(-3) + 4

Function, h(-3) = -9 + 4

Function, h(-3) = -5

When x = 2, we have:

Function, h(x) = 3x + 4

Function, h(2) = 3(2) + 4

Function, h(2) = 6 + 4

Function, h(2) = 10

When x = 4, we have:

Function, h(x) = 3x + 4

Function, h(4) = 3(4) + 4

Function, h(4) = 12 + 4

Function, h(4) = 16

When x = 5, we have:

Function, h(x) = 3x + 4

Function, h(5) = 3(5) + 4

Function, h(5) = 15 + 4

Function, h(4) = 19

The perimeter of the semi-circle is 59.1 cm

In this question, we have been given the diameter if the semi-circle

d = 23 cm

We need to find the perimeter of the semi-circle.

We know that, the perimeter of the semi-circle of radius 'r' is P = πr + 2r

For diameter d = 23 cm, the radius would be,

r = 11.5 cm

So, the perimeter would be,

P = πr + 2r

P = π × 11.5 + 2 × 11.5

P = (π + 2) × 11.5

P = 59.13 cm

Therefore, the perimeter of the semi-circle is 59.1 cm

A quadratic equation is ax² + bx + c = 0 .  Another name for the terms a, b, and c is quadratic coefficients.

The values of the unknown variable x that fulfill the quadratic equation are the solutions to the problem. Quadratic equations' roots are known as these solutions.

Given equation:  x² - 6x +9=11

Subtract 11 on both sides

x² - 6x +9 +(-11) =11 - 11

x² - 6x - 2 = 0

Solving using the quadratic formula,

x = [tex]\frac{-b + \sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]\frac{-b - \sqrt{b^{2}-4ac } }{2a}[/tex]

x = [tex]\frac{6 + \sqrt{-6^{2}-4(-2) } }{2}[/tex]  or  [tex]\frac{6 - \sqrt{-6^{2}-4(-2) } }{2}[/tex]

x = [tex]\sqrt{11} + 3[/tex] or   [tex]\sqrt{11}-3[/tex]

Multiply 0.50 by 896.

Answer:

Step-by-step explanation:

The step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.

In this question, we have been given Taylor is solving a literal equation (x + 3y) / 2 = 40v

We have been given her steps that she used to solve for y.

We need to find an error in the steps.

First we solve given literal equation for y.

(x + 3y) / 2 = 40v

x + 3y = 40v × 2                     .................(Multiply both the sides by 2)

x + 3y = 80v

x + 3y - x = 80v - x                 ...................(Subtract x from both the sides)

3y = 80v - x

y = (80v - x)/3                          ............(Divide each side by 3)

If we observe Taylor's steps, we can see that there's an error in the step 3y = 80v + x.

Therefore, the step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.

The exact solution and its approximation rounded to two decimal places are 2. 6213 and 2. 62 respectively.

An algebraic expression can be described as a mathematical or arithmetic expressions that is composed of arithmetic terms, factors, constants, variables, and coefficients.

These expressions are also made up of arithmetic operations which includes;

From the information given, we have that;

(2x − 1)^2 = 18

Find the square root of both sides, we have;

√(2x − 1)^2 = √18

Note that square root rules out the square, we have;

2x - 1 = 4. 24264

collect like terms

2x = 4. 24264 + 1

2x = 5. 24264

Using a proportional relationship, the table relating the number of guests and number of tables is given by the image at the end of the answer.

A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality represented by k, according to the equation below:

y = kx.

In the context of the problem, the variables are given as follows:

He'll have 4 tables for every 20 guests, hence the constant is given as follows:

k = 4/20 = 1/5 = 0.2.

Hence the relation is:

y = 0.2x.

For 1 table, the number of guests is:

0.2x = 1 -> x = 5.

For 8 tables, the number of guests is:

0.2x = 8 -> x = 8/0.2 = 40.

For 35 guests, the number of tables is:

y = 0.2 x 35 = 7.

For 50 guests, the number of tables is:

The value of the fraction given as - 1 3/4 - (-8 1/3) - (- 4 1/4) will be 10 5/6.

It should be noted that a fraction is simply used to represent the numbers that aren't whole. The commutative property of addition states that the sum is unaffected by the order of the addends.

According to the associative property of addition, the grouping of integers does not affect the sum.

Based on the information given, the fraction is illustrated as:

= - 1 3/4 - (-8 1/3) - (- 4 1/4)

Note that (-) × (-) = +

Therefore,

= - 1 3/4 - (-8 1/3) - (- 4 1/4)

= - 1 3/4 + 8 1/3 + 4 1/4

The LCM of the denominator is 12

= - 1 9/12 + 8 4/12 + 4 3/12

Answer:

Value of x is 2 and value of k is 0.999.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.

Given Data

At t=0, Water Volume is 3,000 Litres

The volume of water in the tank equals t hours later.

As it is also stated, there is x% less water in the tank at the conclusion of every hour than there was at the beginning.

After an hour, the amount of water is equal to 3,000 - = 3,000 - 30 x

Water consumption after two hours = (3,000 - 30 x) - (3,000 - 30 x)

×= (3,000 - 30 x) (3,000 - 30 x)

Also,

= 288120

⇒300000 - 3000 x - 3000 x + 30 x²

= 288120

⇒ 30 x ² - 6,000 x + 11880= 0

When we multiply both sides by 30, we get

⇒ x² - 200 x + 396=0

reducing the quadratic equation to factors

(x -198)(x-2) = 0

x = 198,

x = 2

Which suggests that x = 2 might be the answer to this equation.

Also,

V₁ = 3000- 30(2)

V₁ = 3000 - 60

V₁ = 2940

Answer: 846.12

Step-by-step explanation:

The number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.

For the given question;

Let the number of calories present in carrot is 'x'.

Let the number of calorie present in celerystalk is 'y'.

Carrot has 13 more calories than celerystalk.

Thus,

x = y + 13   ......eq 1

Now, 5 carrots and 10 celery stalks have total 170 calories.

The equation becomes.

5x + 10y = 170

Substitute the value of x from eq 1.

5(y + 13) + 10y = 170

Simplify the equation;

5y + 65 + 10y = 170

15y = 105

y = 7 (number of calories in stalk of celerystalk)

Put the value of y in eq 1.

x = y + 13

x = 7 + 13  

x = 20 (number of calories in stalk of carrot)

Thus, the number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.
