Answer:

The actual height of 1 story is 15 feet.

Step-by-step explanation:

The given scale is

2 inches = 25 ft

We know the 10 story building has a height of 12 inches, but we need the actual height of 1, that is, the height of 1 story in feet.

Let's divide to find the number of inches per story

There are 1.2 inches per story.

Now, we know , let's use the rule of three

Therefore, the actual height of 1 story is 15 feet.

Answer:

15 ft

Step-by-step explanation:

2 inches  = 25 ft

12 inches = x ft

2 x 6 = 12

25 x 6 = 150

150 ft = 10 stories

150/10 = 15

Each story = 15ft

Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Answer:

area = 82 cm²

Step-by-step explanation:

The figure comprises a trapezoid, a triangle and a square.

Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.

Area of square : (side)²

= (2)²

= 4 cm²

Area of triangle : ½ × b × h

= ½ × 3 × 12

= 3 × 6

= 18 cm²

Area of trapezoid : ½ × (a + b) × h

= ½ × (5+5) × 12

= ½ × 10 × 12

= 5 × 12

= 60 cm²

Now, area of the composite figure :

= 4 + 18 + 60

= 22 + 60

= 82 cm²

Answer:

Step-by-step explanation:

If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.

Its area is:

Add the area of the square with sides of 2 cm:

Total area is:

Answer:

Step-by-step explanation:

-2÷1 = -2

4÷(-2) = -2

-8:4 = -2

So this is a geometric sequence with a common ratio of -2

Therefore:

the 5th term:   -8×(-2) = 16

the 6th term:   16×(-2) = -32

Step-by-step explanation:

My knowledge. Hope it's correct!

Given:

Two angles form a linear pair.

The measure of one angle is z and the measure of the other angle is 2.4 times z plus 10°.

To find:

The measure of the smallest and biggest angle.

Solution:

Two angles form a linear pair. The measure of one angle is z.

The measure of the other angle is 2.4 times z plus 10°, i.e., [tex]2.4z+10^\circ[/tex].

We know that if two angles form a linear pair then their sum is 180 degrees.

[tex]z+(2.4z+10^\circ)=180^\circ[/tex]

[tex]3.4z=180^\circ -10^\circ[/tex]

[tex]3.4z=170^\circ[/tex]

Divide both sides by 3.4.

[tex]z=\dfrac{170^\circ}{3.4}[/tex]

[tex]z=50^\circ[/tex]

Now, the measure of other angle is:

[tex]2.4z+10^\circ =2.4(50^\circ)+10^\circ[/tex]

[tex]2.4z+10^\circ =120^\circ+10^\circ[/tex]

[tex]2.4z+10^\circ =130^\circ[/tex]

Therefore, the measure of the smaller angle is [tex]50^\circ[/tex] and the measure of the bigger angle is [tex]130^\circ[/tex].

Answer:

11.28 units squared

Step-by-step explanation:

Area of a circle is

[tex]\pi {r}^{2} [/tex]

each square has an area of 1

There are four semi-circles, which make two complete circles.

the area of the 5 squares plus the area of the two circles equals the total area.

5 + 2(3.14) = 11.28

Answer:

See Explanation

Step-by-step explanation:

Given

The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot

Required

Drivers that travel below 80 mph

A stem and leaf plot has the following syntax: Stem | Leaves

Take for instance:

7 | 2 3 4 7

The above represents 72, 73, 74 and 77

Using the above illustration, the attached leaf plot can be interpreted as:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

80 81... and so on

The drivers that drive below 80 mph are:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

And the frequency is: 12

Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)

Answer:

answer: 31.4

Step-by-step explanation:

the formula to finding circumference is just diameter × pi we arent given the diameter so we have to figure it out but what we do know is the radius is half of the diameter so 5 x 2 = 10 so now that we have the diameter we just multiply by pi so 10 × 3.14 = 31.4 Hope this helps!

Answer:

10 π m

Step-by-step explanation:

Given,

Radius ( circle ) = 5 m

To find : Circumference ( circle ) = ?

Formula : -

Circumference ( circle ) = 2πr

Circumference ( circle )

= 2 x π x 5

= 10 π m

Well..They gave you the hint all you have to do is apply the formula

hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]

So lets do this

axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

Answer:

x = number of pairs of sandals sold = 287

Total pair of sneakers and sandals sold = 451 pairs

Step-by-step explanation:

Sneakers = 4

Sandals = 7

Sneakers : sandals = 4 : 7

If the store sells 164 pair of sneakers

Let

x = number of pairs of sandals sold

Sneakers : sandals = 164 : x

Equate both ratios to find x

4 : 7 = 164 : x

4/7 = 164/x

4 * x = 7 * 164

4x = 1,148

x = 1,148/4

x = 287

x = number of pairs of sandals sold = 287

how many pair of sneakers and sandals does the store sell in all ?

Total pair of sneakers and sandals sold = Sneakers + sandals

= 164 + 287

= 451 pairs

Total pair of sneakers and sandals sold = 451 pairs

Answer:

-32x-48y

Step-by-step explanation:

multiply: -4 (8x) - 4 (12y) = -32x-48y

Answer:

32x - 48y

Step-by-step explanation:

when you distribute, -4 has to go to both -8x and 12y  

so -4 times -8x = 32x

-4 times 12 = -48y

Final answer: 32x - 48y
