Answer:

Hexa is a prefix meaning six.

Step-by-step explanation:

An example of this would be a hexagon, it has six sides, and the word of course has the prefix, "hexa."

The area of the circle is the amount of space it occupies, and the area of the circle is 156.25π

The circumference, C is given as:

C = 25π

Start by calculating the radius using:

C = 2πr

So, we have:

2πr = 25π

Solve for r

r = 12.5

The area is then calculated using:

A = πr²

So, we have:

A = π * 12.5²

Evaluate

A = 156.25π

Hence, the area of the circle is 156.25π

Answer:

SA = 76 cm²

Step-by-step explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

Substitute the values above and multiply:

SA = 2(lw) + 2(wh) + 2(hl)

SA = 2(4)(2) + 2(2)(5) + 2(5)(4)

SA = 2(8) + 2(10) + 2(20)

SA = 16 + 20 + 40

SA = 76 cm²

[tex]\textsf{a)} \quad y=(x+1)^2-4[/tex]

[tex]\textsf{b)} \quad y=2(x-4)^2-2[/tex]

Step-by-step explanation:

Vertex form of a parabola:  [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex and [tex]a[/tex] is some constant)

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-(-1))^2-4\\y & =a(x+1)^2-4\end{aligned}[/tex]

Substitute the point (1, 0) into the formula:

[tex]\begin{aligned}\implies a(1+1)^2-4&=0\\4a-4&=0\\4a &=4\\a &=1\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+1)^2-4[/tex]

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-4)^2+(-2)\\y & =a(x-4)^2-2\end{aligned}[/tex]

Substitute the point (6, 6) into the formula:

[tex]\begin{aligned}\implies a(6-4)^2-2&=6\\4a-2 & =6\\4a &=8\\a &=2\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

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

The equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) is

The Correct option is (C) and (E)

A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.

The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .

= -3x+18 + 12 x -8x-3

=x +15

The corresponding equation to the above equation is:

C. x+15

D. (12 x - 11x) + (3-18)

= x-15

E. (12 x - 11x) + (18-3)

= x+15

F. (12 x - 11x) + (-6+3)

= x-3

As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is

The division of something into distinct portions, or the sharing of something among other persons, locations, or things, is referred to as division.

A group of 9 friends received a combined total of 233 text messages in two hours. One person received 25 messages.

Then the number of the remaining messages will be

Answer:x < 3/14

Step-by-step explanation:

-14x > -3

x < 3/14

Answer: x<3/14

Step-by-step explanation:

Answer:

Step-by-step explanation:

2 2/9? maybe because 1/8 is 6 times bigger than 1/2, so if you add 6 to 2 2/3 it would be 2 2/9?

You would need 1/4 white paint to mix with 2 2/3 quarts of blue paint to make the same shade of paint.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The amounts of each type of paint as fractions of the total amount of paint: 1/2 quart of blue paint is 1/(1+1/2) = 2/4 = 1/2 of the total amount of paint, and 1/8 quart of white paint is 1/(1+1/2+1/8) = 1/8 of the total amount of paint.

So the ratio of blue paint to white paint in the original mixture is 1/2 to 1/8, or 4 to 1. To make the same shade of paint with 2 2/3 quarts of blue paint, we need to use the same ratio of blue paint to white paint.

So we need 1/4 as much white paint as blue paint, which is (1/4) × 2 2/3 quarts = 2/3 quart of white paint.

The error in the original solution was not correctly finding the ratio of blue paint to white paint in the original mixture, which is necessary to determine the correct amount of white paint to mix with a different amount of blue paint to create the same shade.
