ABCD is a trapizoid of bases [AB] and [DC], M and N are the midpoint of [AD] and [BC] if DC=11cm and MN=9cm then AB=

Answers

Answer:

[tex]AB = 7[/tex]

Step-by-step explanation:

Given

[tex]DC = 11[/tex]

[tex]MN = 9[/tex]

Required

Find AB

Since MN is the midpoint, then:

[tex]MN = \frac{1}{2}(AB + DC)[/tex]

[tex]9 = \frac{1}{2}(AB + 11)[/tex]

Multiply by 2

[tex]2 * 9 = \frac{1}{2}(AB + 11)*2[/tex]

[tex]18 = AB + 11[/tex]

[tex]AB = 18 - 11[/tex]

the heights of the peach trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.8 feet.
what is the height of a peach tree with a z-score of -0.5?

Enter your answer rounded to the nearest tenth, in the box.

Answers

Answer:

i think 1.8 not sure tho

Answer:

Z-score Formula: z = (x - μ)/σ

Plug in: -0.5 = (x - 12.5)/1.8

Solve: -0.5 * 1.8 = x - 12.5

-0.9 = x - 12.5

-0.9 + 12.5

x = 11.6

Therefore, the height of a peach tree with a z-score of -0.5 is 11.6 feet.

He base rate for a state's workers compensation insurance for a service station attendant is $5.12 per $100.00 paid in wages the payroll for scott park service station for march is 5,784.00. What is the monthly premium for workers compensation insurance?

Answers

Answer:

$2961.41

Step-by-step explanation:

Base rate for a state workers compensation insurance = $5,12 per $100 paid in wages

Scott park payroll for march = $5784 ( inclusive of insurance payment )

Determine the monthly premium for insurance

$5.12 = $100

First; calculate how many $100 are in $5784

 = 5784 / 100 = 578.4

Hence the monthly premium for workers compensation insurance

= $5.12 * 578.4

= $2961.41

Suppose y varies directly with x, and y = 14 when x = 2. What direct variation equation relates x and y? What is the value of y when x = 6? Explain. Show your work

A. The equation y = 2x relates x and y. When x = 6, y =2(6) or 12.
B. The equation y = 14x relates x and y. When x = 6, y =14(6) or 84.
C. The equation y = 7x relates x and y. When x = 6, y =7(6) or 42.

Answers

Answer: C. The equation y = 7x relates x and y. When x = 6, y =7(6) or 42.

Step-by-step explanation:

Using direct variation with the formula:

y = kx

Since y =14, when x = 2.

y = kx

14 = 2k

k = 14/2

k = 7

Therefore, y = 7x

The value of y when x = 6 will be:

y = kx

y = 6k

Recall that k = 7

y = 6 × 7

y = 42

Therefore, the equation y = 7x relates x and y. When x = 6, y =7(6) or 42.

Ana participated in a charity walk. She

A central angle of a circle of diameter 6 cm measures 86°. What is the length of the intercepted arc?
A)
2.8 cm
B)
4.5 cm
C)
5.1 cm
D)
9 cm

Answers

Answer:

B)

4.5 cm

Step-by-step explanation:

The formula for arc length when our central angle is in degrees =

2πr(θ/360)

θ = 86°

Diameter = 6cm Radius = Diameter /2

Radius = 6cm/2 = 3cm

Hence,

Intercepted arc length = 2 × π × 3 (86/360)

= 2 × π × 3 × 0.2388888889

= 4.5029494701 cm

Approximately = 4.5 cm

Option B is the correct answer

The proportional relationship between the distance driven and the amount of time driving is shown in the
following graph.
Which statements about the graph are true ?
A. The y- coordinate of point A represents the distance driven in 4 hours.
B. The distance driven in 1 hour is 80 km
C. None of the above

Answers

The distance driven in 1 hour is 80 km. Therefore, option B is the correct answer.

The given time graph shows the proportional relationship between the distance driven and the amount of time driving.

What is a distance-time graph?

If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

From the graph, we can see that object A moved 400 km in 5 hours time.

So, in 1 hour the distance travelled by object =400/5=80 km

Therefore, option B is the correct answer.
