Hilary wants to fill a mini cake pan with batter to make a mini cake for Phillip's party. The cake pan is 4.0 inches long, 9.0 inches wide, and 2.2 inches deep. What is the volume of the cake pan?
The volume of the cake pan Hilary wants to use is calculated using the formula for the volume of a rectangular prism. With dimensions of 4.0 inches by 9.0 inches by 2.2 inches, the volume is 79.2 cubic inches.
To find the volume of the cake pan that Hilary wants to use for making a mini cake for Phillip's party, we need to use the formula for the volume of a rectangular prism, which is Volume = length × width ×height. Given the dimensions of the cake pan are 4.0 inches long, 9.0 inches wide, and 2.2 inches deep, we can calculate the volume as follows:
Volume = length × width × height
Volume = 4.0 in× 9.0 in × 2.2 in
Volume = 79.2 in³
Therefore, the volume of the cake pan is 79.2 cubic inches.

A factory used 396.25 pounds of tomatoes to make 6.25 batches of salsa. How many pounds of tomatoes were used in each batch?
Answer:
63.4 pounds of tomatoes were used in each batch
Step-by-step explanation:
A factory used 396.25 pounds of tomatoes to make 6.25 batches of salsa.
Or, In 6.25 batches of salsa 396.25 pounds of tomatoes were used.
In 1 batch of salsa , [tex]\dfrac{396.25}{6.25}[/tex] pounds of tomatoes will be used.
i.e. In 1 batch of salsa , 63.4 pounds of tomatoes will be used.
Hence, 63.4 pounds of tomatoes were used in each batch
a fellow classmate tosses 4 coins and finds that 3 of them come up tails. Which of the following is the best conclusion for her to come to?
A. She needs to keep flipping the coins until she gets a 50% in heads to determine if they are fair.
B. The coins are unfair
C. This could easily happen with a fair coin after only 4 flips
D. If she flips the coins one more, they will all come up heads
Answer:
Option C -This could easily happen with a fair coin after only 4 flips.
Step-by-step explanation:
Given : A fellow classmate tosses 4 coins and finds that 3 of them come up tails.
To find : Which of the following is the best conclusion for her to come to?
Solution :
According to statement,
A fellow classmate tosses 4 coins and finds that 3 of them come up tails.
This could be happen when coin is tossed or flip 4 times and the coin must be fair.
As when we flip 4 coins the possible outcomes were
HHHH THHH HTHH TTHH
HHHT THHT HTHT TTHT
HHTH THTH HTTH TTTH
HHTT THTT HTTT TTTT
So, The best conclusion for her is Option C
This could easily happen with a fair coin after only 4 flips.

A figure has a vertex at (-1, -3). If the figure has line symmetry about the y-axis, what are the coordinates of another vertex of the figure?
A) (-3, -1)
B) (3, 1)
C) (1, -3)
D) (-1, 3)
Answer:
(1,-3)
Step-by-step explanation:
A figure has a vertex at (-1, -3). If the figure has line symmetry about the y-axis, find the coordinates
When a vertex is reflected over y axis then the value of y remains the same , the x value becomes -x
for (x,y) reflected over line symmetry y axis
(x,y) becomes (-x,y)
So the vertex (-1,-3) becomes (1,-3)
Lily is 14 older than her little brother Ezekiel. In 8 years, Lily will be twice as old as Ezekiel will be then. What is Lily and Ezekiel's combined she?
The combined age of Lily and Ezekiel is 42.
Lily is 14 older than her little brother Ezekiel. In 8 years, Lily will be twice as old as Ezekiel will be then. What is Lily and Ezekiel's combined To be determined.
In mathematics it deals with numbers of operations according to the statements.
Let the age of lily be L and the gare of her brother Ezekiel is E.
Lily is 14 older than her little brother Ezekiel.
L = 14 + E - - - - - -(1)
In 8 years, Lily will be twice as old as Ezekiel will be then.
L = 2(E)
put L in equation 1.
2E = 14 + E
2E - E = 14
E = 14
Now put E in equation 1
L = 14 + 14
L = 28
Combined age of Lily and Ezekiel's = 28 + 14
= 42
Thus, the combined age of Lily and Ezekiel's is 42.

Hermina cut a 10" by 15" piece of cardboard down the diagonal
Hermina can calculate the length of the diagonal on her 10" by 15" rectangle of cardboard by using the Pythagorean theorem. The formula states that the square of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides, the length and the width. Thus, by inputting the values into the formula, we get a diagonal length of about 18.03".
Explanation:The question involves calculating the length of the diagonal on a rectangular piece of cardboard. In mathematics, the Pythagorean theorem is used to calculate the length of a diagonal. In this case, the length and width of the rectangle are given as 10" and 15" respectively. We can apply the theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. The diagonal here acts as the hypotenuse, with the other two sides being the length and width of the rectangle. Therefore, the length of the diagonal is the square root of the sum of squares of these sides, which would be sqrt(10^2 + 15^2), resulting in approximately 18.03".
