x2 + 3x + 1 = 0
what are the 2 values for x ?

Answer:

Noah's expression is wrong because he used the wrong coefficients for the variables, and he used a subtraction sign instead of an addition sign.

The correct expression is 2m + 10c

Step-by-step explanation:

Noah is incorrect because he used the wrong coefficients for both of the variables in the expression.

Since muffins are $2 each, and m is the number of muffins, the amount of money made from the muffins is 2m, not 10m.

Similarly, since cakes are $10 each, and c is the number of cakes, the amount of money made from the cakes is 10c, not 2c.

Noah is also incorrect because he used a subtraction sign instead of an addition sign. The amounts made from the muffins and cakes have to be added together.

Putting all of this together, the correct expression is 2m + 10c.

Answer:

The number of tiles needed is 1.105.[tex]\overline 3[/tex] tiles

Step-by-step explanation:

The given data on the dimensions of the bathroom wall are;

The length, l = 2.5 m

The width, w = 2.05 m

The height, h = 3 m

The dimension of the tiles with which the walls are to be covered = 15 cm by 15 cm

The dimensions of the tiles in meters = 0.15 m by 0.15 m

The number of tiles savings made on the doors and windows of the bathroom = 108 tiles

Let 'A' represent the surface area of the bathroom wall, we have;

A = h·w + h·w + l·h + l·h = 2·h·w + 2·l·h =  2·h·(w + l)

∴ A = 2 × 3 m (2.5 m + 2.05 m) = 27.3 m²

The surface area per tile, Tₐ = 0.15  × 0.15  = 0.0225

∴ Tₐ = 0.0225 m²/tile

The number of tiles needed, n = A/Tₐ - 108 tiles

∴ n = 27.3 m²/(0.0225 m²/tile - 108 tiles  = [tex]\left (1105+\dfrac{1}{3} \right )[/tex] tiles = 1.105.[tex]\overline 3[/tex] tiles

The number of tiles needed, n = 1.105.[tex]\overline 3[/tex] tiles.

Answer:

C f - g

Step-by-step explanation:

the surface area of a cylinder consists of the two circles (1 at the top, 1 at the bottom) and the surrounding "mantle", the side of the cylinder, that connects the two circles.

there are no other parts.

so, when the function for the whole surface area is

SA(x) = f(x) = 2×pi×x² + 4×pi×x

and the side/ mantle area by itself is

g(x) = 4×pi×x

then when ignoring the side/mantle area part in f(x) the only thing left of the main function f(x) is the surface area of the two circular bases.

therefore, the solution for the function of the surface area of only the two circular bases must be the main function minus the function for the side/mantle area.

=> f - g

There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

To find the average approaching 3.5, we need to use the concept of the mean or expected value.

The expected value of a random variable is the long-run average value that we would expect to get if we repeat an experiment many times.

In this case, we can consider each roll of a die as an experiment, and the value of the die as the random variable.

Assuming that the die is fair and has six equally likely outcomes, each with a value between 1 and 6, the expected value of the die is:

E(X) = (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5

Therefore, if we roll the die many times, we would expect the long-run average value to be 3.5.

Now, if we have rolled the die 3200 times and the average so far is 3.51, we can calculate the sum of all the values rolled so far as:

Sum = (Average so far) x (Number of rolls) = 3.51 x 3200 = 11232

To find the average approaching 3.5, we need to calculate the average of the remaining rolls. Let's call the number of remaining rolls "n". Then we have:

Average approaching 3.5 = (Sum of remaining rolls) / n

We know that the total number of rolls is 3200, so the number of remaining rolls is:

n = 3200 - (number of rolls already rolled)

n = 3200 - 3200 = 0

Therefore,

There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

Answer: B

Step-by-step explanation:

The requried value of x in the triangle ABC is 4. Option B is correct.

In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.

Since the given triangle ABC and EDF are congruent triangles,
So,
BC = EF

Answer:

SAS

Step-by-step explanation:

Given: I is the midpoint of ME and SL

which prosulate can be used to prove the triangles congruent?

The solution is, SAS prosulate can be used to prove the triangles congruent.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

given that,

I is the midpoint of ME and SL

so, we get,

MI = IE

and, SI = IL

now, we know that,

the opposite angles are equal to each other.

so, we have,

angle MIS = angle LIE

so, for triangle MSI & LIE

We get,

MI = IE

SI = IL

angle MIS = angle LIE

so, we get,

both the triangles congruent by SAS.

Hence, The solution is, SAS prosulate can be used to prove the triangles congruent.

Land area of Charlotte, NC = [tex]3\times 10^2[/tex] square miles

Scale to be used,

1 square miles = [tex]6.4\times 10^2[/tex] square acres

By this scale,

[tex]3\times 10^2[/tex] square miles = [tex](6.4\times 10^2)\times(3.2\times 10^2)[/tex] square acres

                                  = [tex](6.4\times 3)\times 10^{2+2}[/tex]

Step-by-step explanation:

You have to use Pythagorean Theorem because the other side is not listed of the triangle

Pythagorean Theorem: a² + b² = c²

a²  + 20²  = 25²

a²  + 400 = 625

625-400 = a²

a²  = 225

Find the square root of 225 to find the missing length

[tex]\sqrt{225}[/tex] = 15 (this is the missing length for QS

Answer:

(-2/7,2/3)

Step-by-step explanation:

Let's solve for x.

−7x+3y=2

Step 1: Add -3y to both sides.

−7x+3y+−3y=2+−3y

−7x=−3y+2

Step 2: Divide both sides by -7.

−7x/ −7 = −3y+2/ −7

x= 3/ 7 y+ −2/ 7

Answer:

x= 3/ 7 y+ −2/ 7

Let's solve for y.

−7x+3y=2

Step 1: Add 7x to both sides.

−7x+3y+7x=2+7x

3y=7x+2

Step 2: Divide both sides by 3.

3y/ 3 = 7x+2/ 3

y= 7/ 3 x+ 2/ 3

y= 7/ 3 x+ 2/ 3
