Answer:

Step-by-step explanation:

The Standard Penetration Test (SPT) is a widely used geotechnical test used to estimate soil strength. A SPT hammer drives a split barrel sampler at the bottom of a drive rod and recovers soil samples.

Answer:

Part A

1. After 4 weeks of work, Jeremy has saved 300

2. Jeremy worked 8 weeks in order to save $600

3. For every one week of work, Jeremy saved 75 dollars

4. If Jeremy works 15 weeks, then he can expect to save 1,125 dollars

Part B

1. Saeed orders 15 meals and his total cost of delivery is $24

2. Saeed paid $32 to have 20 meals delivered

3. For every meal delivered, Saeed is charged $1.6

4. If Saeed pays $19.20 in delivery fees then he ordered 12 meals

Step-by-step explanation:

Part A

The given graph gives the proportional relationship between total amount saved and the number of weeks worked

1. Reading from the graph, at the point where the vertical line from point 4 touches the line of the graph, an horizontal line to the vertical y-axis touches the y-axis at 300

Therefore;

After 4 weeks of work, Jeremy has saved 300

2. The point where an horizontal line from point 600 on the vertical y-axis touches the line of the graph, a vertical line drawn to the horizontal, x-axis touches the x-axis at 8

Therefore;

Jeremy worked 8 weeks in order to save $600.

3. The rate of change of the amount saved to the number of weeks worked, 'm', for the given proportional relationship (straight line relationship, passing through the origin) is given as follows;

Rate of change, m = Constant = y/x

∴ Rate of change of the amount saved to the number of weeks worked = (300-0)/(4 weeks- 0 week) = 75/week

Therefore;

For every one week of work, Jeremy saved 75 dollars

4. The amount Jeremy would have saved in 15 weeks, 'A', is given as follows;

A = m × n

Where;

m = The rate of change of the amount saved to the number of weeks worked = 75/week

n = The number of weeks worked

∴ A = 75/week × 15 = $1,125

Therefore;

If Jeremy works 15 weeks, then he can expect to save 1,125 dollars

Part B

From the graph, we have;

1. From the graph there is a proportional relationship between the total cost of delivery and the number of meals

At the point a vertical line drawn to the line of the graph from 15 on the horizontal axis (number of meals), a horizontal line drawn to the vertical y-axis touches the y-axis at 24

Therefore;

1. Saeed orders 15 meals and his total cost of delivery is $24

2. From the point where the horizontal line from 32 on the vertical axis touches the linear graph of the relationship between the total cost of delivery and the number of meals, a vertical line drawn down to the horizonal axis touches the horizontal x-axis at 20

Therefore;

Saeed paid $32 to have 20 meals delivered

3. The rate of change of the total cost of delivery to the number of meals, 'm', is given as follows;

m = y/x (for proportional relationships)

Taking any corresponding 'x' and y-values

m = 16/10 = 32/20 = 24/15 = 1.6 Dollars/meal

Therefore;

For every meal delivered, Saeed is charged $1.6

4. From m = y/x = 1.6

When y = $19.20

x = y/m = $19.20/($1.6/meal) = 12 meals

Therefore;

If Saeed pays $19.20 in delivery fees then he ordered 12 meals.

Answer:

10

Step-by-step explanation:

12 x 2 = 24

2 x 2 = 4

10 x 2 = 20

20 + 4 = 24

Answer:

Midpoint of AB              = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)

x coordinate of point c = a

                                  N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)

                                  M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)

                                MA = √(3a / 2 - 0)² + b / 2 - 0)²

                                       = √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4

                                NB = √(a / 2 - 2a)² + (b / 2 - 0 )²

                                      = √( a / 2 - 4a / 2)² + (b / 2 - 0)²

                                      = √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4

Answer:

-10 3/4:)

Step-by-step explanation:

Given:

The equation of a circle is:

[tex](x-3)^2+y^2=32[/tex]

To find:

Center and the circumference of the circle.

Solution:

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]         ...(i)

Where, (h,k) is center and r is the radius.

We have,

[tex](x-3)^2+y^2=32[/tex]           ...(ii)

On comparing (i) and (ii), we get

[tex]h=3,y=0,r=\sqrt{32}[/tex]

So, the center of the circle is (3,0) and the radius of the circle is [tex]\sqrt{32}[/tex].

Now, the circumference of the circle is:

[tex]C=2\pi r[/tex]

[tex]C=2(3.14)(\sqrt{32})[/tex]

[tex]C=35.525045[/tex]

[tex]C\approx 35.5[/tex]

Therefore, the circumference of the circle is about 35.5 units.

Answer:

120

Step-by-step explanation:

4x, 7x, 9x

9x=54

we need to find 4x+7x+9x

9x=54⇒x=6

4x+7x+9x=20x=20×6=120

120 sweets

Step-by-step explanation:

4:7:9

Total Parts = 4+7+9=20

Oldest(9)= 9/20

9/20P= 54 Sweets

Total Sweets = 54/ (9/20) =120

Answer:

It is a function.

Step-by-step explanation:

In a function, each input exists one unique output. In this case, this is a function because each input isn't assigned to multiple outputs, therefore y is a function of x.

Answer:

67°

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

From, trigonometry

tan(θ) = opposite/ adjacent

✓The helicopter is 665 feet from ground.

✓Distance of the helicopter and the line of sight of the girl will be the OPPOSITE SIDE, which is

(665ft - 5 ft)

= 600 ft

✓ from the figure, we can see the distance on the Horizontal side which is the ADJACENT SIDE as ( 280 ft)

✓angle of depression can be calculated as

tan(θ) = opposite/ adjacent

tan(θ)= (660/280)

tan(θ)= 2.357

tan-1=(2.357)

θ= 67°

Hence, angle of depression is 67°

Given:

The graph of a line.

To find:

The slope of the graphed line.

Solution:

From the given graph it is clear that the line passes through the points (-2,2) and (2,5). So, the slope of the line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{5-2}{2-(-2)}[/tex]

[tex]m=\dfrac{3}{2+2}[/tex]

[tex]m=\dfrac{3}{4}[/tex]

Therefore, the slope of the given graphed line is [tex]m=\dfrac{3}{4}[/tex].

ANSWER:10 apples and a ded body

Answer:

JK = 8

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the measures of the parts of one chord is equal to the product of the measures of the other chord, that is

x(x + 4) = (x + 1)(x + 2) ← expand parenthesis

x² + 4x = x² + 3x + 2 ( subtract x² + 3x from both sides )

x = 2

Then

JK = x + 4 + x = 2x + 4 = 2(2) + 4 = 4 + 4 = 8
