Bob is 6 feet 2 inches tall.
There are

What is Bob's height in meters?
Z
A) 1.8796 meters
B) 18.796 meters
C) 74 meters
D) 15.748 meters
E) 1.5748 meters
F) None of the above

Answers

Answer:

A, 1.8796

Step-by-step explanation:

First, convert everything to inches

6 × 12 = 72

72 + 2 = 74

Now, we convert the inches to centimeters

2.54 × 74 = 187.96

Next, we convert to meters

187.96 ÷ 100 = 1.8796

So, your answer would be A, 1.8796 meters

Derrick needs to figure out how he’s doing on his test scores so far this year. You can help by calculating the mean and the median to get an overall picture of his scores. Below are all of his scores:

25, 40, 68, 85, 95, 98, 70, 78, 85, 100

Answers

Answer:

Mean = 74.4

Median = 81.5

Step-by-step explanation:

25, 40, 68, 85, 95, 98, 70, 78, 85, 100

Mean = Sum of values / Number of values

Number of values = 10

= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10

= 744/10

= 74.4

Median

Rearranging the given data

= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100

Formula for median = 1/2(n + 1)th value

n = 10

Hence

1/2(10 + 1)th value

1/2(11)th value

= 5.5 th value

This fall between the 5th and 6th value

5th value = 78

6th value = 85

Hence: 78 + 85/2

= 163 / 2

= 81.5

Help me find the area of the question c please

Answers

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = [tex]\frac{a+b}{2} h[/tex]

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

[tex]A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16[/tex]

Hence the area of shape C = 16 square units

Answer:

rectangle A's area: 12, 3 x 4 = 12

Area b: 1 x 4 = 4 divided by 2 = 2, the base is 1 height is 4. Multiply given lengths, then multiply by 1/2 because formula of a triangle is BH x 1/2. To get your answer of 2.

Area C: 3 + 5 = 8, 8 x 4 = 32, 32 divided by 2 = 16, formula of a trapezoid is base 1 + base 2 x height x 1/2. In this case 5 is your base and base 2 is 3. Add them up to get 8. We then multiply 8 by the height which is 4 if you count from the top to bottom in the middle. 8 x 4 = 32. 32 x 1/2 = 16 (basically just dividing by 2).

Your school is organizing a carnival. You are building a ramp for a game. The surface of the ramp will be 7 feet long with a total rise of 2 feet. Find the angle of elevation of the ramp.

Answers

Answer:

[tex]\theta=16.6^{\circ}[/tex]

Step-by-step explanation:

Given that,

The surface of the ramp will be 7 feet long with a total rise of 2 feet.

We need to find the angle of elevation of the ramp. We can use trigonometry to find it such that,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

P is perpendicular

H is hypotenuse

Here, P = 2 feet, H = 7 feet

So,

[tex]\sin\theta=\dfrac{2}{7}\\\\\theta=16.6^{\circ}[/tex]

So, the angle of elevation of the ramp is equal to [tex]16.6^{\circ}[/tex].

Now, looking at the inequalities, we can see that the second inequality does not have an equal to assigned

Whenever we want to plot this kind of inequality, we are going to use the dotted line in place of the thick line used in cases where we have the equal to assigned to the inequality

Bob's can make 10 hamburgers in 3 minutes. How many
minutes does it take Bob's to make one burger?

Answers

Answer:

3 minutes and 34 seconds

Answer:

Bob's can make one burger in 0.3 minutes, or 18 seconds.

Step-by-step explanation:

Bob's can make 10 hamburgers in 3 minutes. To determine how long it takes Bob's to make a single hamburger, we divide the 3 minutes by the 10 hamburgers.

3/10 = 0.3 minutes

It takes him 0.3 minutes to make one burger.

We could go further and convert this time to seconds. To do this, we multiply 0.3 minutes by 60 seconds.

0.3 ⋅ 60 = 18 seconds

Bob's can make one hamburger in 18 seconds.
