To find the two numbers, we set up a system of equations and solve it to find the values of x and y.

To solve this problem, we can set up a system of equations. Let's represent the two numbers as x and y. Since the sum of the two numbers is 24, we can write the equation:

x + y = 24

Twice the smaller number, which is 2x, is 3 less than the larger number, so we can write the equation:

2x = y - 3

Now we can solve this system of equations using substitution or elimination method. Let's start with substitution method:

Therefore, the two numbers are 7 and 17.

the two numbers are 7 and 17.

The problem states that the sum of two numbers is 24 and that twice the smaller number is 3 less than the larger number. Let's denote the smaller number as 'x' and the larger number as 'y'. According to the first condition, we have:

x + y = 24 ... (1)

For the second condition, twice the smaller number (2x) is 3 less than the larger number (y), so we have:

2x = y - 3 ... (2)

To find the two numbers, we solve these equations simultaneously. By rearranging equation (2), we get y = 2x + 3. Substituting this into equation (1), we have:

x + (2x + 3) = 24

3x + 3 = 24

3x = 24 - 3

3x = 21

x = 7

Now that we have the smaller number, we substitute x back into equation (1) to find the larger number:

7 + y = 24

y = 24 - 7

y = 17

Thus, the two numbers are 7 and 17.

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] × area of base × height

here area of base = 24 and height = 6, so

V = [tex]\frac{1}{3}[/tex] × 24 × 6 = 8 × 6 = 48 in³

Answer:

The value of c is 10.9 ⇒ 3rd answer

Step-by-step explanation:

* Lets study the problem

* In ΔABC

- a, b, c are the lengths of its 3 sides, where

# a is opposite to angle A  ⇒ BC

# b is opposite to angle B  ⇒ AC

# c is opposite to angle C  ⇒ AB

- m∠C = 68°  

- a = 8 ⇒ side BC

- b = 11 ⇒ side AC

- Find the value of c ⇒ side AB

* We have the length of two sides and the measure of the

  including angle between them and we want to find the

  length of the side opposite to this angle then the cosine

  rule is the perfect way

∵ c² = a² + b² - 2ab cos(C)

∵ a = 8 , b = 11 and m∠C = 68°

∴ c² = (8)² + (11)² -2(8)(11) cos(68°)

∴ c² = 119.069 ⇒ take √ for both sides

∴ c = 10.9 units

* The value of c is 10.9

Answer:

A. he held the tube iver the flame too long

Final answer:

The cracking of the test tube could have been caused by thermal shock due to overheating one side of the test tube by holding it over the flame for too long, or by heating an empty test tube meant for containing liquids.

Explanation:

When heating substances in a test tube, such as in a chemistry lab, it's important to take certain precautions to prevent accidents, such as the cracking of the test tube. One potential cause for a test tube to crack is thermal shock, which can occur if the test tube is heated too quickly or unevenly. This brings us to option A: 'He held the test tube directly over the flame for too long'. Holding a test tube directly in the flame can cause one side to expand more rapidly than the other due to the heat, leading to stress and cracking, particularly if the glass isn't designed to withstand rapid temperature changes. To avoid this, the test tube should be moved in and out of the flame to heat it gently and evenly, and a boiling chip can be used to prevent superheating and ensure smooth boiling.

Option B suggests another possibility: 'He did not add water to the test tube'. While not adding water to a test tube might not directly cause it to crack, if the test tube was meant to contain a liquid and was instead heated while empty, the glass could become too hot and weaken, increasing the chance of breaking. It's always important to follow specific instructions for each experiment, including whether or not to add substances to the test tube.

Both scenarios emphasize the importance of careful temperature control when heating glassware to avoid breakage from thermal stress.

Answer:

x = -2

Step-by-step explanation:

In order to find the axis of symmetry, we will have to find the x-value of the vertex.

Vertex = (-b/2a, f(-b/2a))

In x² + 4x + 6,

a = 1 , b = 4 , c = 6

Vertex = (-4/2,f(-4/2))

Vertex = (-2,f(-2))

We have found the x-value of the vertex which is -2.

Hence, line/axis of symmetry is x = -2

The axis of symmetry for f(x) = [tex]x^2 + 4x + 6[/tex]  is -2.

Given that,

Based on the above information, the calculation is as follows:

Here we have to determine the x-value of the vertex.

[tex]Vertex = (-b\div 2a, f(-b\div 2a))[/tex]

Now as per the given equation i.e [tex]x^2 + 4x + 6[/tex]

Here,

a = 1 , b = 4 , c = 6

Now  

[tex]Vertex = (-4\div 2,f(-4\div 2))[/tex]

 = (-2,f(-2))

= -2

Therefore we can conclude that the axis of symmetry for f(x) = [tex]x^2 + 4x + 6[/tex]  is -2.

Points to remember

solution of a quadratic equation ax² + bx + c = 0

x = [-b ± √(b² - 4ac)]/2a

It is given that, x² + 9x + 10 = 0.

To find the solution

Here a = 1, b= 9 and c = 10

x = [-b ± √(b² - 4ac)]/2a

 = [-9 ± √(9² - 4*1*10)]/2*1

 = [-9 ± √(81 - 40)]/2

 =  [-9 ± √(41)]/2

 = [-9 ± √41]/2

Therefore the solution of given quadratic equation  =  [-9 ± √41]/2

Step-by-step explanation:

The formula of a Surface Area of a sphere:

[tex]S.A.=4\pi R^2[/tex]

R - radius

We have

[tex]S.A.=1024\pi\ in^2[/tex]

Substitute:

[tex]4\pi R^2=1024\pi[/tex]               divide both sides by π

[tex]4R^2=1024[/tex]             divide both sides by 4

[tex]R^2=256\to R=\sqrt{256}\\\\R=16\ in[/tex]

To find the radius of a sphere when you are given the surface area, you can use the formula for the surface area of a sphere, which is:
\[ \text{Surface area of a sphere} = 4 \pi r^2 \]
where \( r \) is the radius of the sphere. Now, let's solve for \( r \) using the surface area provided:
We are given that the surface area is \( 1024 \pi \) square inches, so we set that equal to the formula for the surface area:
\[ 1024 \pi = 4 \pi r^2 \]
To solve for \( r^2 \), we first divide both sides of the equation by \( 4 \pi \):
\[ \frac{1024 \pi}{4 \pi} = \frac{4 \pi r^2}{4 \pi} \]
On simplifying the left-hand side and cancelling \( 4 \pi \) from the right-hand side, we get:
\[ 256 = r^2 \]
Now, to solve for \( r \), we take the square root of both sides:
\[ r = \sqrt{256} \]
This results in:
\[ r = 16 \]
So, the radius of the sphere is 16 inches.

The radius of the circle with a circumference of 12.56 inches is 2 inches, calculated using the formula C = 2πr and rearranging it to find the radius.

The circumference of a circle is given by the formula C = 2πr, where C stands for the circumference and r stands for the radius of the circle. The value of π (pi) is approximately 3.14159. Given the circumference of the circle as 12.56 inches, you can find the radius by rearranging the equation to r = C / (2π).

Now, let's calculate the radius using the given circumference:

r = 12.56 inches / (2 × 3.14159)

r = 12.56 inches / 6.28318

r = 2 inches

Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.

To find the measure of the radius of the circle given its circumference, we can use the circumference formula of a circle, which is:
\[ C = 2 \pi r \]
Where \( C \) is the circumference, \( \pi \approx 3.14159 \), and \( r \) is the radius of the circle.
Now, we know the circumference (\( C \)) is 12.56 inches. We can solve for the radius (\( r \)) by rearranging the formula:
\[ r = \frac{C}{2 \pi} \]
Plugging the given circumference into the equation, we get:
\[ r = \frac{12.56}{2 \times \pi} \]
\[ r = \frac{12.56}{2 \times 3.14159} \]
\[ r = \frac{12.56}{6.28318} \]
\[ r = 2 \]
Rounding the result to two decimal places as may be required for some comparisons, we still get \( r = 2.00 \) inches.
Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.

Answer:

the solution is (5, 6)

Step-by-step explanation:

Please reserve " × " for representing multiplication, and " x " as a variable name.

Starting with the system

6x-5y= 0  

4×-5y = -10​

multiply the 2nd equation by -1.  This results in the system

6x - 5y  = 0  

-4x + 5y = 10

and combining these two equations results in

​ 6x - 5y  = 0  

-4x + 5y = 10

------------------

2x         = 10, or x = 5.

Substituting 5 for x in the first equation, we get

6(5) - 5y = 0, or 5y = 30.  Then y = 6, and the solution is (5, 6).

The inside angle next to the 70 degrees would be 180 - 70 = 110 degrees.

The measure of an outside angle is equal the the sum of the two opposite inside angles.

X is an exterior angle and it's 2 opposite inside angles are 40 and 110.

X = 40 + 110 = 150 degrees.
