Answer:

QUESTION:

If x = 8, what is the value of x(17 - x)?

ANSWER:

x( 17 - x) = ?

8( 17 - 8) = ?

8 X 17 = 136

8 X (-8) = -64

Final answer:

Answer:

260.0234 cm

Step-by-step explanation:

The formula for area of a circle is π r².

Since the radius is half of the diameter, we must divide the diameter by 2.

18.2/2 = 9.1

Next, we must multiply 9.1 x 9.1.

This gives us 82.81

Now we must multiply 82.81 by pi (3.14).

82.81 x 3.14 = 260.0234

Therefore, the area of the circle is 260.0234.

Answer:

The answer is 37.6 degrees

Step-by-step explanation:

Since a right angle is 90 degrees in total, to find the missing degree subtract 52.4 from 90 to find the value of x.

90-52.4= 37.6 degrees

37.6 degrees is your answer  

Hope this helps

Answer:

88.67

Step-by-step explanation:

We know that a triangle's angles adds up to 180 degrees.We can make a equation: x+15+32+2x=180

x=44.3

Don't forget to times 2 to get L

Then L equals 88.67.

Answer:

482895ft^2

Step-by-step explanation:

Given data

Width= 657ft

Length= 735ft

We know that area A

A= Length* Width

A=657*735

A= 482895ft^2

Hence the area is 482895ft^2

Step-by-step explanation:

Answer:

x ≈ 47°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{11}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{8}{11}[/tex] ) ≈ 47° ( to the nearest degree )

Step-by-step explanation:

The frequency of a radio wave that has a wavelength of 3000m is 100 kHz

(a) Wavelength = 500 m

We know that,

[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{500}\\\\f=600\ kHz[/tex]

(b) Frequency, f = 800 kHz

[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{800\times 10^3}\\\\\lambda=375\ m[/tex]

Hence, this is the required solution.

Step-by-step explanation:

AB = X

AC² = AD × AB

60² = 36 × AB

3600 = 36 × AB

AB = 3600/36

AB = 100

So, if AB = X then the value of X is 100.

Answer:

b 5/12

Step-by-step explanation:

The question is incomplete. The complete question is :

A population of mutant Venus fly trap plants are taking over an island in the South Pacific, capturing everything from insects to small rodents. When they were first discovered they covered 4 square kilometers. As the population grows, the plants spread and cover more land. Use the table to write an equation.

Solution :

It is given that:

Venus fly trap plant  is capturing everything on its way from small insects to other small rodents.

When they were first discovered, it covered an area of 4 square kilometers. But as more population grew and as years passed by, they spread over large land and covered more land.

Now from the table, it is seen that :

It covered 4 km square when discovered.

Then it covered 6.68 km square in the first year.

It covered 11.16 km square in the second year.

It covered 18.63 km square in the third year.

It covered 31.11 km square in the fourth year.

Therefore the equation which represents the growth is given by :

Step-by-step explanation:

The number of students that  should the teacher predict will participate in the program is option C. 108 students

Since 15% of the students would be interested in a summer creative writing program and there are 720 students

So, the number of students should be

= 15% of 720

= 108

Therefore, The number of students that  should the teacher predict will participate in the program is option C. 108 students

Answer:

The correct answer is B

Step-by-step explanation:

Both of their medians are equal and Ami's range is larger than Lolo's range :)

The medians are equal, and the range of Ami’s scores is greater than the range of Lolo’s scores

Option B is the correct answer.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

Lolo's quiz:

Scores: 12, 13, 13, 14, 14, 14, 15, 16, 16, 17, 17, 19

Median.

= (14 + 15)/2

= 14.5

Range,

= 19 - 12

= 7

Ami's score:

Scores: 10, 12, 12, 13, 13, 14, 15, 16, 17, 17, 18, 18

Median.

= (14 + 15)/2

= 14.5

Range.

= 18 - 10

= 8

We can say that,

The median is the same for both and Ami's range is greater than Lolo's.

Thus,

The medians are equal, and the range of Ami’s scores is greater than the range of Lolo’s scores

The solution is, Figure a is a half sphere and figure b is a cylinder.

In geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. Everything we see in the world around us has a shape.

here, we have,

from the given figure, we have,

the given shape has two parts,

the upper half is a half sphere.

Hemisphere includes the prefix hemi-, meaning "half". The northern and southern hemispheres are divided by the equator, the circle halfway between Earth's two poles. The eastern and western hemispheres aren't divided so exactly, since there are no poles in the Earth's east-west dimension.

and, the part b is a cylinder.

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.

Hence, The solution is, Figure a is a half sphere and figure b is a cylinder.

Answer:

Tan 60 = √3

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

Tan 60 = Opp/Hyp

From the diagram given,

Opp = YZ = ?

Hypotenuse = XY = 42

Find the length of YZ using Pythagorean Theorem:

YZ = √(42² - 21²) = √1,323

YZ = √(441 × 3) = 21√3
