Answer:

C. 10z(x - 2y)

Step-by-step explanation:

10xz − 20y

Factor the terms

Factors of 10xz   =          2 ×       5 × x ×        z

Factors of -20yz = (-1) × 2 × 2 × 5 ×        y × z

Identify their greatest common factor

The common factors are 2, 5, and z. The greatest common  factor is 10z.

Rewrite them with the GCF as a factor

 10xz = 10z ×     x

-20yz = 10z × (-2y)

Replace the terms in the original expression with the factored terms

10xz − 20yz = 10z(x) + 10z(-2y)

Use the distributive property to isolate the greatest common factor

10z(x) + 10z(-2y) = 10z(x - 2y)

Answer: [tex]6.185in^3[/tex]

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

[tex]V_{cylinder}=\pi r^2h[/tex]

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

[tex]r=\frac{d}{2}[/tex] (Where d is the diameter)

 [tex]r=\frac{3in}{2}=1.5in[/tex]

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

[tex]V_{can}=\pi (1.5)^2(1.75in)=12.37in^3[/tex]

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

[tex]V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3[/tex]

Answer:

"The diameter of the bacterium is 10 times greater than that of the virus."

Step-by-step explanation:

Size of bacteria is 10^-6

Size of virus is 10^-7

Definitely the bacteria is larger. How many times larger? We find that by dividing the diameter of bacterium by the diameter of virus.

Let's do this:

[tex]\frac{10^{-6}}{10^{-7}}\\=\frac{0.000001}{0.0000001}\\=10[/tex]

Hence, the bacterium is 10 times larger than the virus

The volume of the cone is 144π units³

Given,

Radius of cone (r) = 4

Height of cone (h) = 27

The volume of a cone is defined as the amount of space occupied by a cone in a three-dimensional plane.

∵ Volume of the cone (V)=1/3πhr²

Substitute the values of h and r,

V = 1/3π(27)(4)²

V = 144π units³

Hence, The volume of the cone is 144π units³

Final answer:

To round 2.684 to the nearest hundredth, you look at the third decimal place. Since it's a 4, you don't round up, keeping the second decimal at 8. The rounded number is 2.68.

Explanation:

To round the number 2.684 to the nearest hundredth, we need to look at the third digit after the decimal point, which is 4 in this case. Since the third digit (4) is less than 5, we do not round up the second digit. Therefore, the second digit after the decimal remains as 8, and the number 2.684 rounded to the nearest hundredth is 2.68.

So, the correct answer from the options provided is:

A. 2.68

Answer:

Step-by-step explanation

If breadth =x

Length =2x

Perimeter = 2x +x +2x+x

36=6x

X=6

Therefore breadth =6

Length =12

The question asks about finding the length and width of a rectangle given its perimeter. By setting up and solving an equation, we found that the rectangle's width is 6 inches, and its length is 12 inches.

Given that the length of a rectangle is 2 times its width, and the perimeter of the rectangle is 36 inches, we are asked to find the length and width of the rectangle. We can start by defining the width as 'w' and the length as '2w'. The formula for the perimeter of a rectangle is 2(length + width). We can substitute our definitions of length and width into this formula to get 2(2w + w) = 36. Simplifying this gives 3w = 18, so the width is 6 inches. Therefore, the length is 2 × 6 = 12 inches.

Final answer:

The absolute value of -6 is 6, so the value of the expression 5 + |-6| is 11.

Explanation:

The absolute value of a number is its distance from zero on a number line, regardless of direction.

Hence, the absolute value of -6 is 6. Now let's solve the expression 5 + |-6|.

First, we find the absolute value of -6, which is 6. Adding this to 5, we get:

5 + |(-6)| = 5 + 6 = 11.

Thus, the absolute value of 5 + |-6| is 11.

Answer:

D

Step-by-step explanation:

We know that parallel lines have equal slopes.

Let's transform the given equation to the form y = mx + b to find the slope (m is the slope). Shown below:

[tex]-4x+y=2\\y=4x+2[/tex]

So the slope is 4. Hence the parallel line will have a slope of 4.

Now we can write the equation of the parallel line as :

[tex]y=4x+c[/tex]

Since the line goes through (-1,3), we can plug in -1 into x and 3 into y to find out c:

[tex]y=4x+c\\3=4(-1)+c\\3=-4+c\\3+4=c\\c=7[/tex]

Now we know both m and c, so the equation of the parallel line is:

[tex]y=4x+7[/tex]

Answer choice D is right.

The world population is approximately 23 times larger than the population of the United States.

The question is asking how many times larger the world population is compared to the population of the United States. You can determine this through division. In this case,
6.9 × 109 (the world population) divided by 3 × 108 (the US population) equals approximately 23. This means that the world population is approximately 23 times larger than the population of the United States.

https://brainly.com/question/12287830

#SPJ3

The answer is expressed in standard notation as 23.

To calculate how many times larger the world population is compared to the United States, we divide the world population by the population of the United States. Given the world population as 6.9 × 10^9 people and the U.S. population as 3 × 10^8 people, we perform the following calculation:

6.9  × 10^9 ÷ 3 × 10^8 = 23 times larger.

When we divide these two numbers, we subtract the exponents (since the bases are the same) resulting in 10^1, which is just 10. Multiply the non-exponential part: 6.9 ÷ 3, which equals 2.3. Therefore, 2.3 × 10 tells us that the world population is 23 times larger than the population of the United States. To write this in standard notation, we simply say the world population is 23 times larger.

Answer: OPTION A

Step-by-step explanation:

Apply the formula for calculate the distance between two points to know the value of the diameter of the circle:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\D=\sqrt{(-5-(-5))^2+(-2-6)^2}\\D=8[/tex]

The equation of the circle is standard form is:

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

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

As we know the diameter, we can find the radius:

[tex]r=\frac{8}{2}=4[/tex]

Substitute it into the equation:

[tex](x-h)^2+(y-k)^2=(4)^2[/tex]

[tex](x-h)^2+(y-k)^2=16[/tex]

Then, the answer is:

[tex](x+5)^2+(y-2)^2=16[/tex]

➷ The formula for circumference is [tex]\pi d[/tex]

1) [tex]\pi d = 31.4[/tex]

Divide both sides by [tex]\pi[/tex]

d = 9.99 (consider this to be 10)

Half this to find the radius

10/2 = 5

It would be figure B.

2) [tex]\pi d = 37.68[/tex]

Divide both sides by [tex]\pi[/tex]:

d = 11.99 (consider this to be 12)

Divide by 2 to find the radius:

12/2 = 6

It would be figure C.

3) area = [tex]\pi r^2[/tex]

[tex]\pi r^2 = 153.86[/tex]

r^2 = 48.97515909

r = 6.998 (consider this to be 7)

It would be figure D

4) [tex]\pi r^2 = 113.04[/tex]

r^2 = 35.98174

r = 5.998 (consider this to be 6)

It would be figure C.

5) radius = diameter / 2

radius = 3

[tex]\pi (3)^2 = 28.27433[/tex]

D-->K

O-->O

Step-by-step explanation:

Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.

Here Angle E corresponds and is congruent to Angle R in these congruent triangles.

Angle D is congruent and corresponds to Angle K for these congruent triangles.

Angle O is equal to Angle O as they are vertical angles across a vertex.

Congruent triangles, in mathematics, are triangles that are of the same size and shape, meaning their corresponding sides and angles are equal. An example would be two triangles each with sides of 3, 4, and 5 units.

In mathematics, specifically in geometry, congruent triangles are defined as triangles that have the same size and shape. This means that their corresponding sides are of equal length, and their corresponding angles are of equal measure. The concept of congruence is important in many aspects of geometry, including the study of shapes, symmetry, and transformations.

If we have two triangles, Triangle A (with sides of 3, 4, and 5 units respectively) and Triangle B (with sides of 3, 4, and 5 units as well), these two triangles are congruent, as the lengths of their corresponding sides are equal. You could rotate, flip or move one to coincide exactly with the other, showcasing their congruency.
