Dylan prepared 49 kilograms of dough after working 7 hours. How many hours did Dylan work if he prepared 70 kilograms of dough? Solve using unit rates.

Answer:

x = 12

Step-by-step explanation:

Vertical angles are congruent

50 = 4x + 2  Subtract 2 from both sides

48 = 4x  Divide both sides by 4

12 = x

Answer:

3000 = 2*2*2*2*3*5*5*5

Step-by-step explanation:

6000/2 = 3000

3000/3 = 1000

1000/2 = 500

500/2 = 250

250/2 = 125

125/5 = 25

25/5 = 5

5/5 = 1

3000 = 2*2*2*2*3*5*5*5

An expression is a set of numbers or variables combined using the operations + , – , × or ÷ . Arithmetic expression that contains only numbers and mathematical operators and algebraic expression that contains variables, numbers and mathematical operators.

(6 x 10⁻⁴)(6 x10⁻⁶) is the given expression

Now multiply 6 with 6 and   10⁻⁴ with 10⁻⁶

36 x 10⁻⁴x  10⁻⁶

We need to add the powers of same base.

The decay factor for the annual rate of change of -0.1 % is 0.999.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 0.1 % = - 0.1 / 100 = - 0.001

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.001)

B = 1 - 0.001

B = 0.999

Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.999.

y  = -x +2 an equation in slope-intercept form of the line that bisects the angle.

What exactly does slope intercept mean?

Given:

Angled formed by ray BA and ray BC is 90 degrees.

To find:

The equation of line that bisects the angle formed by ray BA and ray BC.

If a line bisects the angle formed by ray BA and ray BC, then it must be passes through point B and makes angles of 45 degrees with ray BA and ray BC.

It is possible if the line passes though point B(-1,3) and other point (-2,4).

Equation of line is

y - y₁  = y₂ - y₁/x₂ - x₁  ( x - x₁)

y - 3 = 4 - 3 / - 2 - ( -1)  ( x - ( -1)

y - 3 = 1/-1 ( x + 1 )

y - 3 = -x -1

Add 3 on both sides

y = -x -1 + 3

Step-by-step explanation:

Answer:

Number 1 is 4

Number 2 is 10

Step-by-step explanation:

Number 1 is x

Number 2 is 3x - 2

so x + (3x - 2) = 14

x + 3x - 2 = 14

4x = 14 + 2

4x = 16

x  = 4

so

Number 1 is 4

Number 2 is 3(4) - 2 = 10

Based on the information provided,  neither Brandi nor Sharana jogged at a slower rate.

Rate can be defined as the speed at which an event happens or an object moves over a particular period of time.

It is also known as the ratio at which two or more term, quantities or objects with different units are compared.

The formula for rate is expressed as;

Rate = distance/ time

From the information given, we have that;

Substitute the values

Brandi's rate = 1/ 30 = 0. 03

Sharana's rate = 1. 5/ 45 = 0. 33

From the values gotten, we can see that neither Brandi nor Sharana jogged at a slower rate.

a. Han wrote (1/2, 0) as x-intercept of the line instead of (2, 0).

b. The x-intercept: (2, 0)

The y-intercept: (0, 5)

The y-intercept of a line is the corresponding value of y when the value of x is equal to zero.

On the other hand, the x-intercept of a line is the corresponding value of x when the value of y is equal to zero.

Y-intercept is (0, b), while x-intercept is (b, 0), where b is the value of the point on the axis that is being intercepted.

In slope-intercept form, y = mx + b or y = b + mx, the y-intercept is represented as b, which is (0, b).

Given the equation in slope-intercept form as y = 5 - 10/4x, the y-intercept, b = 5. Therefore, is expressed as (0, 5).

To find the x-intercept, substitute y = 0 into y = 5 - 10/4x:

0 = 5 - 10/4x

Solve for x

-5 = -10/4x

-20 = -10x

-20/-10 = x

x = 2

The x-intercept is (2, 0), while the y-intercept is (0, 5).

Therefore:

a. The Han got the x-intercept wrong, it should be (2, 0), not (1/2, 0).

b. The x-intercept is (2, 0), while the y-intercept is (0, 5).

The sum of all decent fractions with a denominator of 20 is 4.

Thus, option (d) is correct.

To find the sum of all decent fractions whose denominator is equal to 20, consider fractions with numerators that are coprime to 20 (i.e., the numerator and 20 have no common factors other than 1).

The decent fractions with a denominator of 20 can be written as:

1/20, 3/20, 7/20, 9/20, 11/20, 13/20, 17/20, and 19/20.

To find the sum, add up these fractions:

Sum = 1/20 + 3/20 + 7/20 + 9/20 + 11/20 + 13/20 + 17/20 + 19/20

Sum = (1 + 3 + 7 + 9 + 11 + 13 + 17 + 19) / 20

Sum = 80 / 20

Sum = 4

Therefore, the sum of all decent fractions with a denominator of 20 is 4.

Thus, option (d) is correct.

A function that gives the length of the hypotenuse of an isosceles right triangle with side length s is given by h(s)=s√2 and the length of the side of the triangle is approximately 4.24 inches.

The hypotenuse of a right angled triangle is defined as the longest side of the triangle. The hypotenuse is also located opposite the right angle.

From the Pythagorean Theorem we know that for a right angled triangle, the sum of the square of the legs of the triangle is equal to the square of the hypotenuse.

Given legs of the right triangle is s. Let us consider a function h(s) for the hypotenuse.

Therefore we can define the function h(s) as

h(s)=s√2

The inverse of the function can be written as

y=s√2

or, s=y²/2

Hence the inverse function is:

h⁻¹(s)=s²/2

Now for hypotenuse = 6 inches.

Each side can be calculated using the inverse function h⁻¹(s)=s²/2.

s=6÷√2

or, s=4.242...

Hence the length of the side of the triangle is approximately 4.24 inches.

The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.

The trench will require 9168 cubic feet of dirt to be removed.

Here, we are given that a homeowner is digging a 3 -ft-deep trench around the perimeter of his property.

Length of the property = 210 feet

Breadth of the property = 180 feet

Let us now consider one side of the 180-foot-long trench.

There are two such trenches, each with a width of 4 feet and a height of 3 feet.

Thus the volume of the trench = 2(length × breadth × height)

Volume = 180 × 4 × 3 × 2

= 4320 cubic feet

Now we are left with two other sides of the trench with the following dimensions-

Height = 3ft

Breadth = 4ft

Length = 210 - 8 = 202ft

Thus, volume = 202 × 4 × 3 × 2

= 4848 cubic feet

Thus, the total volume of the trench = 4848 + 4320 = 9168 cubic feet.

Hence, The removal of 9168 cubic feet of earth is necessary.
