The errors on scale 1 and scale 2 are 15% and 6%.

This talks about how correct a scale is over a time.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Scale 1, measured weight = 85, and actual weight = 100.

Scale 2, measured weight = 47, and actual weight = 50.

Error % is given by the formula,

(Actual value - Measured value)/Actual value * 100/1

For scale 1

Measured weight = 85, and actual weight = 100.

Percentage error =(Actual value - Measured value)/Actual value * 100/1

Percentage error = (100-83)/100

Percentage error = 15%

For scale 2

Measured weight = 47, and actual weight = 50.

Measured value)/Actual value * 100/1

Percentage error = (50-47)/50

Percentage error = 6%

Thus the error in scale 1 and scale 2 is 15% and 6%. respectively

In mathematics, the portion or component of the complete item is represented by a fraction. It stands for the equal components of the whole. Both the numerator and denominator are components of a fraction. The top number is referred to as the numerator, while the bottom number is referred to as the denominator.

Given that,

Newton and Descartes have a 70-day summer vacation

They go to camp for 23/70 of their vacation

= 70 × (23/70)

= 23

Next, they travel for 6/35 of their vacation

= 70 × (6/35)

= 12

So, they stay home the rest of their vacation

= 70 - 23 - 12

= 35

Now, they stay home (35 ÷ 7) = 5 weeks.

Answer:Let, one leg be x units.

since the other leg is 9.0 units shorter than the other,

the measure of the other leg =x-9

hypotenuse =13.0 units

According to Pythagorean theorem, the square of the hypotenuse is equal to the sum of squares of the other two sides.  

x^2 +(x-9)^2 =13^2

x^2 + x^2 -18x +81 = 169

2x^2-18x-88=0

Divide the whole equation by 2

x^2 - 9x -44 =0  

Let's use the quadratic formula to find the roots.

formula: x= [-b ± sqrt(b^2-4*a*c)]/2*a  

a=1 b=-9 c=-44

x= [9±sqrt(81+176)]/2

=[9±sqrt(257)]/2

=[9±16.03]/2

=25.03/2 or -7.03/2

length of a triangle cannot be negative,

Therefore, x=25.03/2 =12.52

one leg =12.5 units

other leg =12.52-9 =3.5 units

Step-by-step explanation:

Answer: A. Part A:

f(4) = 9x + 27 = 9(4) + 27 = 36 + 27 = 63

g(4) = x + 3 = 4 + 3 = 7

B. Part B:

f(x) / g(x) = (9x + 27) / (x + 3) = 9

f(4) / g(4) = 63 / 7 = 9

C. Part C:

The domain of f(x) / g(x) is all real numbers except x = -3, because dividing by zero is undefined. The domain of f(x) / g(x) is all real numbers except x = -3.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Part A: f(4) = 63, and g(4) = 7.

My work for Part A:

Step 1: Write the first function substituting x for 3: f(4) = 9 x 4 + 27.

Step 2: Solve the function: f(4) = 9 x 4 = 36, and 36 + 27 = 63.

Step 3: Write the final answer for the first function: f(4) = 63.

Step 4: Write the second function substituting x for 3: g(4) = 4 + 3.

Step 5: Solve the function: g(4) = 4 + 3 = 7.

Step 6: Write the final answer for the second function: g(4) = 7.

Part B: (f/g)(4) = 9.

My work for Part B:

Step 1: Using the numbers from Part A, simply divide f(4) by g(4) to get (f/g)(4): 63/7 = 9.

Step 2: Write the final answer of (f/g)(4): (f/g)(4) = 9.

Part C: The domain of (f/g)(x) is -3 < x ≤ ∞. So, any numbers greater than -3 and less than or equal to infinity, are possible solutions to this function. Therefore, -2, 3, 7, and many more numbers greater than -3 are possible solutions.

The angle x is in the quadrilateral is an alternate angle and x = 29°, y = 73°, and z = 102°.

Angles formed by parallel lines and a transversal as in the quadrilateral can be alternate and are said to be equal

angles x and 29° are alternate angles and

x = 29°

y + x + 78° = 180° {sum of interior angles of a triangle}

y + 29° + 78° = 180°

y + 107° = 180°

y = 180° - 107°

y = 73°

z + 78° = 180° {supplementary angles}

Using Pythagoras theorem, the length of the missing side is 16.6 units

A right-angled triangle's hypotenuse, or side opposite the right angle, has a square length that, according to the Pythagorean theorem, is equal to the sum of the squares of the lengths of the other two sides. Pythagoras, an ancient Greek mathematician, is credited with discovering and proving the theorem, and it bears his name.

The theorem can be written as an equation:

c^2 = a^2 + b^2

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

Data;

Substituting the values and solve for a

a² + b² = c²

17² = a² + 15²

a² = 17² - 15²

Answer: B. 24 - 24 x r = 4.32

Step-by-step explanation:

The percent tip can be found by using the formula: tip = bill x (tip percentage in decimal form)

In this case, Diego's bill was $24 and the tip he paid was $4.32. To find the tip percentage, we can divide the tip by the bill:

tip / bill = 4.32 / 24 = 0.18

To convert the decimal to a percentage, we can multiply the decimal by 100: 0.18 x 100 = 18%

The tip percentage is 18%

So, option B. 24 - 24 x r = 4.32 is the equation that will help find the percent tip that Diego gave the server.

What are equivalent ratios?

The ratios that are same when compared are called equivalent ratios. The equivalentity of two or more ratios can be determined by comparing them to one another. For instance, 1:2 and 2:4 have the same ratio.

A unit rate is a cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

Let x be the total days

equate the ratios of days and hours as shown:

x/34.4 = 1/0.4

[tex]\dfrac{1}{2a}t \ \text{sin} \ \text{at}[/tex] is the solution of (18s)/(s²+36)²​ using convolution property.

Convolution is a mathematical operation on two functions (f and g) that results in a third function (f×g) that expresses how the shape of one is altered by the other. It is a mathematical operation on two functions (f and g) in mathematics, more specifically in functional analysis.

Convolution is a term that describes both the method of computing a function and its result. Its definition states that it is the integral of the product of the two functions after one of them has been shifted and reflected about the y-axis. The result of the integral remains unchanged regardless of which function is chosen to be reflected and shifted before it (see commutativity). The convolution function is created by evaluating the integral across all shift values.

By the Angle - Angle - Angle criteria both ΔDEF and ΔSTR are Similar to each other.

Two triangles are said to be similar triangles if all three corresponding angles are equal or if all three sides are equal. The symbol "∼" is used to represent the similarity between two triangles.    

AAA Similarity Criterion for Two Triangles:

When three angles in two triangles are equal then the two triangles are said to be similar triangles.    

Here we have

ΔDEF and ΔSTR

From ΔDEF  

∠D = 46° and ∠E = 46°  

As we know the sum of angles in a triangle = 180°

=> ∠D + ∠E + ∠F = 180°

=> 46° + 46° + ∠F = 180°

=> ∠F = 180 - 46 - 46

=> ∠F = 88°

Similarly, In ΔSTR
