To make 144 slices of cake, Emma will need 18 large eggs.
To solve this problem, we need to know how much 2 dozen is.
1 dozen = 122 dozen = 24So, for every 24 slices of cake, 3 eggs are needed.
To figure out how many slices of cake 1 egg can make, we can divide 24 by 3.
24 ÷ 3 = 83 ÷ 3 = 1Now, for every 8 slices of cake, 1 egg is needed.
Now, taking 144, we can divide that by 8 to get the number of eggs needed.
144 ÷ 8 = 18Therefore, 18 eggs will be needed to make 144 slices of cake.
Two types of stereos were on sale at a local car stereo dealer.
The J-Series model sold for $II8. The K-Series model sold for $92. During the sale, 32 stereos were sold. The receipts for these stereos totaled $3,230. How many of each type of stereo did the local dealer sell during this sale?
Answer:
11 J- series and 21 K- series
Step-by-step explanation:
create a pair of equations in 2 variables and solve simultaneously.
let x represent J- series and y the K- series , then
x + y = 32 ( subtract x from both sides )
y = 32 - x → (1)
118x + 92y = 3230 → (2)
substitute y = 32 - x into (2)
118x + 92(32 - x) = 3230
118x + 2944 - 92x = 3230
26x + 2944 = 3230 ( subtract 2944 from both sides )
26x = 286 ( divide both sides by 26 )
x = 11
substitute x = 11 into (1)
y = 32 - 11 = 21
11 of J- series and 21 of K- series models were sold

A ballet dancer whose weight is 60 kg performs a move on one foot during which she
applies a pressure of 1,500,000 Pa on the ground. Is she likely to be standing with her foot
flat on the ground, or is she on tiptoe?
It is likely that she is on tiptoe, as a pressure of 1,500,000 Pa is a high pressure for a 60 kg person to be applying with just one foot while standing flat on the ground.
How to know if the dancer is tiptoeingThe unit of pressure Pa is equivalent to Newton per square meter
A mass of 60 kg is converted to force by
= m * g
= 60 * 10
= 600 N
Pressure = Force / Area
Area = Force / Pressure
Area = 600 N / 1,500,000 Pa
Area = 0.0004 square meter
Area = 4 square centimeter
This area is much smaller than the foot hence the dancer is tiptoeing
A pressure of 1,500,000 Pa suggests that the dancer is applying a significant amount of force to a small area, which is typical of being on tiptoe.

Twenty-four 4 cm cube are used to make a solid. If 2 cm cube were used instead, 192 cube would be needed.
A cube is a solid object in three dimensions with six square faces that all have the same length sides. It is one of the five platonic solids and is also referred to as a regular hexahedron. Six square faces, eight vertices, and twelve edges make up the form. Since the 3D figure is a square with equal-length sides, the length, breadth, and height of a cube are all the same measurement.
Number of cubes = Volume of the solid / Volume of the cube

Dexter thinks of a number, x. He subtracts 4 from his number and multiplies the answer by his original number. His answer is 60 a) Use this information to form a quadratic equation of the form x² + ax + b = 0
Answer:
Let y = x - 4, then xy = 60.
Expanding the product on the right side, we have x(x-4) = 60.
Expanding the left side, we have x² - 4x = 60.
Adding 4x to both sides, we have x² = 60 + 4x.
Re-arranging the equation, we have x² - 4x - 60 = 0.
Thus, the quadratic equation is x² - 4x - 60 = 0.

Why is a rhombus not a square?
The primary distinction between a square and a rhombus is that whereas the angles in a square are all 90 degrees, the angles in a rhombus are not.
How do you prove a rhombus is not a square?Since a rectangle need not have equal sides, it is not square. Every square is a rectangle and a rhombus. Due to the fact that every square has an equal number of sides, they are all rhombuses. Due of the 90-degree interior angles, all squares are also rectangles.
The main difference between a square and a rhombus is that whereas a square's angles are all 90 degrees, a rhombus's angles are not. However, both shapes have equal sides on every side.

If none of the tiles are cut, what is the area of the floor in m²?
The area covered by the tiles is 54 square meters.
How to determine the area of a set of tiles
In this problem we find that 2400 square tiles can cover a rectangular school room and 1350 square tiles if each tile is 5 centimeters longer and 5 centimeters wider. Algebraically speaking, this situation is represented by following formula:
2400 · x² = 1350 · (x + 5)²
Where x is in centimeters.
First, expand and simplify by algebraic properties:
2400 · x² = 1350 · (x² + 10 · x + 25)
2400 · x² = 1350 · x² + 13500 · x + 33750
1050 · x² - 13500 · x - 33750 = 0
Second, find the roots of quadratic equation by quadratic formula:
x₁ = 15 or x₂ = - 15 / 7
Since lengths are positive variables, then only valid solution is x = 15 cm.

The slope Ab is 3. The slope of A’B is A’B through the point O
The slope will remain constant, thus it will still be 3.
What is dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size.
Given AB is dilated by a scale factor of 3 to form A'B',
and Point O, which lies on AB, is the center of dilation,
AB has expanded due to the scaling factor, to form A'B'
The image is thus consistent with the preimage according to the laws of dilation.
This suggests that other than the size, the image won't change in any way.
Therefore, the slope will stay the same, the slope of A'B' is 3.
