jacob earns extra cash for mowing neighbors lawns. On Saturday, he earned $70 for mowing 4 yards. On Sunday, he earned $35 for mowing 2 yards. Determine the rate of change of the data, what does jacob earn for each yard he mows?

A. 35/4
B. 70/1
C. 35/2
D.70/2

Answer:

Pair are

30 , 3150  

90, 1050

150, 630

210 , 450

Step-by-step explanation:

Let the numbers be a and b

a = 30x  and  b=30y

HCF of a and b = 30

Product of numbers  = LCM * HCF

30x * 30y = 30 * 3150

       30xy = 3150

           xy = 3150/30 =  105    

1*105   or 3* 35    or   5 * 21    or   7 * 15  

1)  105 = 1*105  

      30xy =30*1 , 30*105 =   (30 , 3150)

2) 105 = 3 * 35

 30xy =   30*3  , 30*35    = 90 , 1050

90 , 1050

3) 150 , 630

4) 210 , 450

Domain = {-2, 0, 1, 2, 5}

Range = {-5, -3, -1, 2, 3}

=============================================================

Explanation:

The domain is the set of allowed x value inputs. We simply list the x coordinates of each point shown on the graph. Those x coordinates are: -2, 0, 1, 2, 5. Use curly braces to indicate we're dealing with a set.

The range is the set of allowed output y values. We list the y coordinates this time and they are -5, -3, -1, 2, 3. These values are also surrounded by a pair of curly braces.

Answer:

5m

Step-by-step explanation:

1.25m multiply by 4 sides equals 5m

The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters.

Perimeter is the addition of an external measure of sides it will always positive.

Perimeter of square = side + side + side + side

Given a table in form of a square,

Side of square = 1.25 m

The external measure of side = length of ant walk

1.25 + 1.25 + 1.25 +1.25 = Length of ant walkt

Length of ant walk = 5 meters.

Hence "The length of which ant walk will be the same as the perimeter of the square thus it will be 5 meters".

Answer:

∠ADB ≅ ∠CBD

Step-by-step explanation:

I did the quiz and got an hundred.

First, find the scale factor:

8/4.6 ≈ 1.73913043478

12/1.73913043478 = 6.9

If triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.

In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

It is given that ΔXYZ ≅ ΔABC.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

When two triangles are similar their scale factor is the same for each side,

The scale factor is  obtained by taking the ratio of their sides,

=  AC / XZ

= 8 / 4.6

= 1.739

The length of side XY is found as,

Scale factor = AB / XY

1.739 = 12 / XY

XY = 6.90

Thus, if triangle XYZ is similar to ABC then the length of the missing side is 6.90. It is obtained by using the scale factor concept.

Answer:

y = 2x + 5

Step-by-step explanation:

First, you must choose two ordered pairs from the table to solve for the slope (m):

Let (x1, y1) = (0, 5)

(x2, y2) = (1, 7)

Substitute the given values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - 5}{1 - 0} = \frac{2}{1} = 2[/tex]

Therefore, the slope (m) = 2.

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b ).  It is also the value of y when x = 0. Looking at the given table, (0, 5) reflects the description of the y-intercept. The y-intercept (b) is the y-coordinate of (0, 5).

Given the slope (m) = 2, and y-intercept (b) = 5, the linear equation is:

y = 2x + 5

Answer:

2/7<4/5<5/6<7/9

Step-by-step explanation:

The fractions in ascending order will be 2/7<7/9<4/5<5/6.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The given number is,

7/9,2/7,4/5,5/6

The fraction with the smallest numerator is the smallest for fractions with the same denominator. Put the numbers 2/7,4/5,5/6,7/9. In ascending order, for instance. The fraction with the highest denominator is the smallest when all the fractions have the same numerator.

The LCM of the denominator 9,7,5 and 6 is 630.

The term equivalence for the denominator is,

490/630,180/630,504/630,525/630

The fractions in ascending order are,

180/630<490/630<504/630<525/630

2/7<7/9<4/5<5/6

Thus, the fractions in ascending order will be 2/7<7/9<4/5<5/6.

Answer:

the value of s=75°

and the value of t=30°

Answer:

s = 75°

t = 30°

Step-by-step explanation:

Since VW = VX,

s = 75

Since all angles in a triangle add upto 180,

75 + s + t = 180

75 + 75 + t = 180

150 + t = 180

t = 30°

6.6

Step-by-step explanation:

Answer: 6

Step-by-step explanation:

Answer: I think the answer is 81, but I don’t have a good explanation.

Step-by-step explanation: if you can find the angle next to 12x-3 (D), and the angle of 8+15x they should equal 180 degrees.

The Triangle Exterior Angle Postulate states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

In the given problem, the exterior angle is < JDC, and its measure is equal to the sum of the measures of < (12x -3)° and < 32°.

We can set up the following equality statement to solve for the value of x, and find out the measure of < JDC:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

Subtract 8 from both sides:

8 - 8 + 15x = 12x - 3 + 32 - 8

15x = 12x + 21

Subtract 12x from both sides:

15x - 12x = 12x - 12x + 21

3x = 21

Divide both sides by 3 to solve for x:

3x/3 = 21/3

x = 7

To verify whether the value for x is correct, substitute x = 7 into the equality statement:

m < JDC° =  < (12x -3)° + < 32°

< (8 + 15x)° = < (12x -3)° + < 32°

[8 + 15(7)]° = [12(7) - 3]° + 32°

8° + 105° = 81° + 32°

113° = 113° (True statement). Therefore, the correct value for x = 7.

Therefore, the correct answer is C) m < JDC = 113°.
