If the mass of an object is 20 g and the volume is 2cm3 what is the density

We have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2

Solution:

Given that,

For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.^2

In order to have a similar rectangle that's area is only 2 in.^2

Thus, we need to find the scale factor

Let "c" be the scale factor

Let "x" be the area of original rectangle

Let "y" be the area of dilated rectangle

Therefore,

[tex]c = \frac{y}{x}\\\\c = \frac{2}{18}\\\\c = \frac{1}{9}[/tex]

Therefore, we have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2

Answer:

Divide them by three.

The solution to f(x) = g(x) is x = -1.

To find the value of x that satisfies the equation f(x) = g(x), we set the two

functions equal to each other and solve for x.

This gives us the equation -2x + 2 = 4x + 8.

Combining like terms, we get 6x = -6.

Dividing both sides by 6, we find that x = -1.

Therefore, the solution to f(x) = g(x) is x = -1.

Answer:

1716 m^3

Step-by-step explanation:

We can find the volume of a triangular prism by thinking about it like this - it's half of a rectangular prism. It's just be cut diagonally. So we can imagine that the measurements of the potential rectangular prism are 6m x 26 m x 22m.

Volume of rectangular prism:

6*26*22 = 3432

Volume of triangular prism:

1/2 of rectangular prism - 3432/2 = 1216

Answer:

Step-by-step explanation:

Volume of the prism is calculated by base and height

V= bh

From the figure, base = 6m

Where height = 26m

V = 26m x 6m

= 156m^2

Maria had 2 yards of trim when she started.

Step-by-step explanation:

Step 1:

All of the sides of the triangle is 22 inches long each.

The total length of the sides of the triangle [tex]= 3(22) = 66.[/tex]

So the total length of the trim for the banner is 66 inches long.

If Maria still has [tex]\frac{1}{2}[/tex] a foot of trim left, she had 6 inches of the trim left.

The length of the trim when she started[tex]=66 +6 = 72[/tex] inches.

Step 2:

Now we need to convert the 72 inches into yards.

We have 1 inch = 0.0277778 yards.

So 72 inches [tex]= 0.0277778(72) = 2.[/tex]

So Maria had 2 yards of trim when she started.

Answer:

5) D

Step-by-step explanation:

4) 416 = 2x² - 6x

2x² - 6x - 416 = 0

x² - 3x - 208 = 0

x² - 16x + 13x - 208 = 0

x(x - 16) + 13(x - 16) = 0

(x - 16)(x + 13) = 0

x = 16, -13(not possible)

So 16 rows

5) y = a(x - h)² + k

y = a(x - 3)² - 7

When x = 1, y = -10

-10 = a (1 - 3)² - 7

-10 = 4a - 7

4a = -3

a = -¾

y = -¾(x - 3)² - 7

Answer:

option 1

Step-by-step explanation:

The shaded area is area of circle - area of 2 congruent triangles

area of circle = πr²

Note that the base and height of both triangles is the radius

Area o triangle = [tex]\frac{1}{2}[/tex] ×  r × r = [tex]\frac{1}{2}[/tex]r²

area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × r² = r²

area of shaded region = πr² - r² = r²(π - 1) → (1)

To represent the area of the shaded region in the figure, use the expression "r² (π+1)" as it closely approximates the calculation for the shaded area.

In the figure described, ABO and GOF are right triangles, and there's a shaded region within these triangles. To represent the area of the shaded region, we can consider the difference between the areas of the larger triangles ABO and GOF and the smaller semicircles centered at O within each triangle.

The area of a triangle is given by (1/2) × base × height, and the area of a circle is πr², where "r" is the radius.

Calculate the area of ABO: (1/2) × AB × AO

Calculate the area of GOF: (1/2) × GO × GF

Calculate the area of one semicircle: (1/2) × πr²

Now, to find the area of the shaded region, subtract the sum of the areas of the two semicircles from the sum of the areas of the two triangles:

Shaded Area = (ABO - πr²) + (GOF - πr²)

So, the representation for the area of the shaded region is:

Shaded Area = (1/2) × AB × AO + (1/2) × GO × GF - πr²

Therefore, option 2, "r² (π+1)," is the closest representation of the area of the shaded region.

Convert all distances to the smallest measure in which all distances can be in the same distance type, so that you can see what is the farthest. Note: inches won't be necessary because that's an unreasonable way to measure distance if you walk very far.

Rowan travelled 450 feet

In a pair of complementary angles, the larger angle is three times the smaller angle. The measurements of the two angles are 22.5 degrees and 67.5 degrees.

In a pair of complementary angles, the larger angle and the smaller angle add up to 90 degrees because complementary angles are two angles that add up to a right angle.

Let's assume the smaller angle is x. According to the given information, the larger angle is three times the smaller angle, so it would be 3x.

Now, we can set up an equation to solve for x. Since the sum of the angles is 90 degrees, we have:

x + 3x = 90

Combining like terms, we find 4x = 90. Dividing both sides by 4, we get x = 22.5.

Therefore, the smaller angle measures 22.5 degrees and the larger angle measures 3 times that, which is 67.5 degrees.

The statement that best describes the property is a · b = b · a.

The commutative property of multiplication states that if there are three numbers x, y, and z, then x × y × z = z × y × x = y × z × x or another possible arrangement can be made.

If you observe the given equation, you will find that the commutative property can be applied. If x = 131, and y = 56 and z = 72, then we know that 131 x 56 x 72 = 72 x 131 x 56.

Given statement:

5 · 2 · 9 = 2 · 5 · 9

For the given set of equations, x = 0 and y = 3.

Step-by-step explanation:

Step 1:

From the question,

[tex]-x + 2y = 6[/tex], take this as equation 1,

[tex]6y =x+18, x - 6y = -18[/tex], take this as equation 2.

Step 2:

When we add equation 1 and equation 2, the x variable is canceled out and y can be calculated.

[tex]-4y = -12, y = \frac{-12}{-4}, y = 3.[/tex]

Step 3:

Substituting this value of y in any of the previous equations we will get x's value.

Here this value of y i.e y = 3 is substituted in equation 1.

[tex]-x + 6 = 6, -x = 6 -6, -x=0, x=0.[/tex]

So we have x = 0 and y = 3.
