The Winning Times For A Race Are Shown In The Table. Which Answer Describes The Rate Of Change From Year

Answers

Answer 1

Answer: The winning time increased by an average of 0.4 second per year from year 2 to year 4.

Answer 2

The winning time for a race displayed in the table would be:

C). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

Hence, The total change in the time is,

= (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

Now, If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, ''Option C'' is the correct answer.

Answer:

Triangles are not similar.

Step-by-step explanation:

Properties of the similarity of two triangles,

1). Corresponding angles of two triangles are equal in measure.

2). Corresponding sides of the similar triangles are proportional.

From the given triangles,

- Corresponding angles of the given triangles are not equal in measure.

- Ratios of the corresponding sides,

 [tex]\frac{KM}{XY}=\frac{CM}{RY}= \frac{KC}{XR}[/tex]

[tex]\frac{53}{53}= \frac{54}{53}= \frac{64}{53}[/tex]

But these ratios are not equal.

Therefore, both the triangles are not similar.

Lorenzo tiene 4 cajas de huevo, cada uno con 50 huevos y 3 cartones del mismo producto con 10 de ellos ¿Cuántos huevos hay en total?

Answers

Responder:

240 huevos

Explicación paso a paso:

Número de cajas de huevos = 4

Huevos por caja = 50

Total de huevos en caja = 50 * 4 = 200 huevos

Número de cajas = 3

Número de huevos por caja = 10

Total de huevos en caja = 10 * 4 = 40 huevos

Huevos totales = (huevos en caja + huevos en cartón)

Total = (200 + 40) = 240 huevos

The angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. Find all the angles of the quadrilateral.

Answers

Step-by-step explanation:

let the ratio be x

now,

3x+5x+9x+13x=360°(sum of angle of quadrilateral is 360°)

30x=360°

x=360/30

x=12°

then,

3x=3×12=36°

5x=5×12=60°

9x=9×12=108°

13x=13×12=156°

so,the angles of quadrilateral are 36°,60°,108°& 156°

In triangle Xyz the measure of angle YXZ is 14.5°, and the measure of angle XYZ is 75°. What is the measure of angle XZY in degrees

Answers

Answer:

90.5 degrees

Step-by-step explanation:

The sum of the angle in triangle XYZ is 180 degrees, hence;

m<XYZ + m<YXZ + <XZY = 180

Substitute the given angles

75 + 14.5 + <XZY = 180

89.5+m<XZY = 180

m<XZY = 180 - 89.5

m<XZY = 90.5 degrees

Hence the measure of angle XZY in degrees is 90.5 degrees

A group of friends were working on a student film that had a budget of $1200. They used $756 of their budget on props. What percentage of their total budget did they spend on props? ​

Answers

Answer: 63

Step-by-step explanation:

756/x = 1200/100

Cross multiply

75600 divided by 1200x

= 63

The percentage of budget used by them is 63%, the calculation is done by using the percentage used method.

Percentage-based problem:

What information do we have?

Amount of budget = $1200

Amount of budget used = $756

Percentage of budget used = [Amount of budget used / Amount of budget]100

Percentage of budget used = [756 / 1200]100

Percentage of budget used = 63%

Step-by-step explanation:

Given

See attachment for triangles ABC and DEF

Options

A) [tex]AC=DF[/tex]

B) [tex]AB=DE[/tex]

C) [tex]\angle B=\angle E[/tex]

D) [tex]\angle A=\angle D[/tex]

Required

Which does not prove the congruence of ABC and DEF using ASA?

From the attachment, we have the following:

[tex]\angle A = \angle D[/tex] --- Angle

[tex]AB = DE[/tex] --- Side

[tex]\angle B = \angle E[/tex] ---- Angle

The ASA theorem means that 1 side of both triangles are equal.

By comparing the listed parameter to the options, we can see that options B, C and D prove that both triangles are congruent by ASA.

However, option A [tex]AC=DF[/tex] cannot be used because that will mean that two sides of both triangles are equal. This does not support the ASA theorem

Step-by-step explanation:

Direct labour rate variance is $3,000

Direct labour efficiency variance is $5,000

Actual direct labour costs is $100,000

Therefore the standard direct labour production during the month of January can be calculated as follows

Function E is a linear function with an initial value of $2$ , and a rate of change of $\frac{1}{3}$
.

Function F is a linear function. The graph of function F includes the points $\left(2,\ 8\right)$ and $\left(0,\ 2\right)$ .

Which statement is true?

A The two functions have the same initial value.

B The two functions have the same rate of change.

C The initial value in function F is greater than the initial value in function E.

D The rate of change in function E is greater than the rate of change in function F.

Answers

Answer:

d

Step-by-step explanation:

The true statement: A The two functions have the same initial value.

What is a linear function?

A linear function has a straight line as its graph.

A linear function has the form shown below.

a + bx = y = f (x).

A linear function consists of one independent variable and one dependent variable. The independent and dependent variables are x and y, respectively.

We know that function E is a linear function with an initial value of 2 and a rate of change of 1/3. Therefore, the equation for function E can be written as:

E(x) = (1/3)x + 2

We also know that function F is a linear function that includes the points (2, 8) and (0, 2).

We can use the two points to find the slope of the line and then use the point-slope form to write the equation for function F.

The slope of F = (8 - 2) / (2 - 0) = 6/2 = 3

Using point-slope form with the point (2, 8), we get:

F(x) - 8 = 3(x - 2)

F(x) = 3x + 2

Now we can compare the two functions.

A. The initial value of function E is 2, while the initial value of function F is 2 + 3(0) = 2. Therefore, statement A is true.

B. The rate of change of function E is 1/3, while the rate of change of function F is 3. Therefore, statement B is false.

C. The initial value of function F is 2, which is the same as the initial value of function E. Therefore, statement C is false.

D. The rate of change of function E is 1/3, which is less than the rate of change of function F, which is 3. Therefore, statement D is false.

Therefore, the only true statement is A. The two functions have the same initial value.

What must you subtract from the expression –5x – 8 in order to make it equivalent to –9x – 1 for all values of x?

Answers

Answer:

the number is 4x - 7

Step-by-step explanation:

Let P be subtracted from -5x - 8 to make it equivalent to -9x - 1.

-5x - 8 - P = -9x - 1

make "-P" the subject of the formula

-P = -9x - 1 + 5x + 8

Collect like terms;

-P = -9x + 5x  - 1 + 8

-P = -4x + 7

divide through by "-1"

P = 4x - 7

Therefore, the number that must be subtracted from -5x - 8 to make it equivalent to -9x - 1 is 4x - 7
