Answer:

A cuboid is a 3-dimensional shape with six rectangular faces, four of which are the sides or lateral faces, and the other two are the base and the top. To solve the problem, we can first find the perimeter of the base of the cuboid by dividing the lateral surface area by the height. In this case, the perimeter of the base is 26 cm.

To find the dimensions of the base, we can set up an equation using the given information. Let x be one of the sides of the base, and let y be the other side. Since one of the sides is 3 cm smaller than the other, we can write the equation as:

x + x - 3 + x + x - 3 = 26 cm

We can simplify the equation by combining like terms:

4x - 6 = 26 cm

Next, we can solve the equation by adding 6 to both sides and then dividing by 4:

4x = 32 cm

x = 8 cm

Therefore, the dimensions of the base of the cuboid are 8 cm x 11 cm (since one side is 3 cm smaller than the other). The perimeter of the base is 26 cm, and the height of the cuboid is 10 cm.

Answer:

(b) mean=95, standard deviation=7.2.

Step-by-step explanation:

To find the new mean and standard deviation, we first need to apply the transformation to the original mean and standard deviation.

The new mean is given by: x*=65+0.6x

Substituting in the original mean of 50, we get: x*=65+0.6(50) = 95

The new standard deviation is given by: s*=0.6s

Substituting in the original standard deviation of 12, we get: s*=0.6(12) = 7.2

Therefore, the new mean and standard deviation are (b) mean=95, standard deviation=7.2.

Answer:

1:1

Step-by-step explanation:

Since the surface area of A is 4 times the surface area of B, and the volume of B is 125 times the volume of C, we can write the following proportion:

(surface area of A) / (surface area of B) = (volume of B) / (volume of C)

(height of A)^2 / (height of B)^2 = (height of B)^3 / (height of C)^3

We can then cross-multiply and simplify to find the ratio of the heights:

(height of A)^2 / (height of C)^2 = (height of B)^3 / (height of B)^3

(height of A)^2 = (height of C)^2

Therefore, the ratio of the height of A to the height of C is 1:1, or simply 1.

The dot plots show that the lowland areas experienced significantly more rainfall than the highland area during spring storms, with a larger range and maximum rainfall.

The dot plots show the rainfall totals for several spring storms in both highland and lowland areas. The dots representing the lowland areas are more spread out and have a larger range compared to the dots representing the highland areas. This indicates that the lowland areas experienced more rainfall than the highland areas during these storms. Additionally, the maximum rainfall for the lowland areas is greater than the maximum rainfall for the highland areas, further emphasizing the difference in rainfall between the two areas. This could be due to a number of factors, such as the higher elevation of the highland areas resulting in less moisture being able to accumulate, or the lower temperature of the highland areas resulting in less evaporation and thus less rainfall. Additionally, the lower elevation of the lowland areas could result in more moisture being able to accumulate, and the higher temperature of the lowland areas could result in more evaporation, leading to increased rainfall. Regardless of the cause, the data from the dot plots clearly show that the lowland areas experienced more rainfall than the highland areas during these spring storms.

Answer: 25 weeks

Step-by-step explanation:

Let W represent the number of weeks

Judy equation is

12W + 300

Cassie equation is

20W + 100

Now let's solve it! Our system of equation is

12W + 300 = 20W + 100

Subtract 300 from both sides

12W = 20W -200

Subtract 20W from both sides

-8W = -200

W = 25 weeks

So, it takes 25 weeks for Judy and Cassie to have the same amount saved.

Answer:

let judy = 300 + 12W

cassie = 100 + 20W

300 + 12W =  100 + 20W

300 - 100 = 20W - 12W

200 = 8W

W = 25

300 +  12(25) = 100 + 20(25)

300 + 300 = 100 + 500

600 = 600

Therefore, it will take 25 days for Judy and Cassie so that they have the same amount saved.

SSS congruence of triangles is proved when all three sides of considered two triangles are congruent(that is, of equal measures).

If two considered triangles have corresponding side pairs congruent(for all three sides), then both the triangles are congruent. This proof of congruence is triangle is done by SSS congruence of triangles (Side Side Side congruence)

Since it is given that the sides CB and FE are congruent, and since it is given that sides AB and DE are congruent too.

Thus, for SSS congruence of both considered triangles, we need the third side pair of the given triangles to be congruent too.

Thus, we need the line segment DF congruent to the line segment AC.

To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

Step-by-step explanation:

first of all, remember for life :

the sum of all angles in a triangle is always 180°.

so, in this right-angled triangle we have therefore

180 = b + 90 + 71

b = 180 - 90 - 71 = 19°

and then regarding a and b :

the sum of all angles around a single point on one side of a line is also always 180°.

why ? because the line can be seen as the extended diameter of a circle, with that point being the center of the circle. and one side of the line is representing half of that circle. and a half-circle is 180°.

so,

a + b = 180

a + 19 = 180

a = 180 - 19 = 161°

FYI, the reason for the first principle (all angles in a triangle are together 180°) is also based on a half-circle concept : any right-angled triangle can be seen as inscribed into a half-circle, with the Hypotenuse (the baseline opposite of the 90° angle) being the diameter of the circle, and the center of the circle being the midpoint of the Hypotenuse.

The volume of a cone is given by the formula:

V = (1/3) * π * r² * h

Where V is the volume, r is the radius, and h is the height.

In this case, we know the radius (4.96) and the volume (102), so we can use the formula to solve for the height.

Substituting the known values into the formula, we get:

102 = (1/3) * π * (4.96)² * h

Dividing both sides by (1/3) * π * (4.96)², we get:

h = 102 / [(1/3) * π * (4.96)²]

Substituting in the value for π, we get:

h = 102 / [(1/3) * 3.14 * (4.96)²]

Which simplifies to:

h = 102 / [(1/3) * 3.14 * 24.1952]

Which simplifies to:

h = 102 / (0.7853 * 24.1952)

Which simplifies to:
