Salim bought a fruitcake, cut off a piece from it, and ate the piece. The dimensions of the cake before and after he cut it, are shown below. What was the volume of the piece that Salim ate?
Answer:
C. 75 cu cm
75 cm³
Step-by-step explanation:
Volume of the cake when Salim bought it = length × width × height
= 15 cm × 6 cm × 5 cm
= 450 cm³
Volume of the cake after Salim cut a piece = length × width × height
= 12.5 cm × 6 cm × 5 cm
= 375 cm³
volume of the piece that Salim ate = Volume of the cake when Salim bought it - Volume of the cake after Salim cut a piece
= 450 cm³ - 375 cm³
= 75 cm³
volume of the piece that Salim ate = 75 cm³
What is the value of (x)?
Answer:
X=6 I hope this helps have a great day!
just divided 24 by 4!
Answer:
x =6
Step-by-step explanation:
You want to solve for the variable, so you have to isolate it on to one side of the equation. You can do this by doing reverse operations. For example, the reverse operation of addition is subtraction. This is reversible as well.
4x = 24
Because 4x is the same thing 4 (x), the reverse operation would be division:
4x = 24

tan 235° = 2tan20°+ tan215°
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215

Jayla has 500 stickers in a collection. She wants at least y stickers in her collection at the end of the month. She buys 25 stickers each day. Write an inequality tha
number of days. Enter your answer in the box provided.
Answer:
20
Step-by-step explanation:
500 divided by 25=20
The required inequality is 500 + 25x ≥ y which represents the given situation.
What is inequality?
Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let x be the number of days Jayla buys stickers.
The total number of stickers Jayla has at the end of the month is 500 + 25x.
To represent the inequality that Jayla wants at least y stickers in her collection at the end of the month, we can write:
500 + 25x ≥ y
This inequality states that the total number of stickers Jayla has (500 + 25d) is greater than or equal to the number of stickers she wants (y) at the end of the month.
It gives the minimum number of days Jayla should buy stickers to achieve her goal.

Identify the tables that represent the relative frequencies of this data by rows or by columns. Round your answers to the nearest hundredth.
Answer:
the middle left and right
The table representing the relative frequencies by rows would be:
King Bed Queen Bed
Mountain 0.58 0.42
Ocean 0.38 0.62
The table representing the relative frequencies by columns would be:
King Bed Queen Bed

What is a relative frequency?Relative frequency is a statistical term that describes the proportion or percentage of times that an event or value occurs within a dataset or sample.
It is calculated by dividing the number of times the event occurs by the total number of observations in the dataset or sample.
We have,
To find the relative frequencies of this data by rows or by columns, we need to divide each count by the total number of rooms occupied. The total number of rooms occupied is:
25 + 18 + 12 + 20 = 75
To find the relative frequencies by rows, we divide each count by the total for that row:
For Mountain View rooms:
King Bed: 25/(25+18) ≈ 0.58
Queen Bed: 18/(25+18) ≈ 0.42
For Ocean View rooms:
King Bed: 12/(12+20) ≈ 0.38
Queen Bed: 20/(12+20) ≈ 0.62
The table representing the relative frequencies by rows would be:
King Bed Queen Bed
Mountain 0.58 0.42
Ocean 0.38 0.62
To find the relative frequencies by columns, we divide each count by the total for that column:
For King Bedrooms:
Mountain View: 25/(25+12) ≈ 0.68
Ocean View: 12/(12+20) ≈ 0.38
For Queen Bedrooms:
Mountain View: 18/(18+20) ≈ 0.47
Ocean View: 20/(18+20) ≈ 0.53
The table representing the relative frequencies by columns would be:
King Bed Queen Bed
Mountain 0.68 0.47
Ocean 0.32 0.53
Note that we round the relative frequencies to the nearest hundredth.
Thus,

Which value of y makes the inequality 3y^2+2(y-5)>8 true
A y=0
B y= -1
C y= -2
D y= -3
Answer:
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.
Step-by-step explanation:
Given the inequality
3y² + 2(y - 5) > 8
For y = 0
substitute y = 0 in the inequality
3y² + 2(y - 5) > 8
3(0)² + 2(0 - 5) > 8
3(0) + 2(-5) > 8
0 - 10 > 8
-10 > 8
FALSE!
-10 can not be greater than 8.
Hence, y = 0 does not make the inequality true.
For y = -1
substitute y = -1 in the inequality
3y² + 2(y - 5) > 8
3(-1)² + 2(-1 - 5) > 8
3(1) + 2(-6) > 8
3 - 12 > 8
-9 > 8
FALSE!
-9 can not be greater than 8.
Hence, y = 1 does not make the inequality true.
For y = -2
substitute y = -2 in the inequality
3y² + 2(y - 5) > 8
3(-2)² + 2(-2 - 5) > 8
3(4) + 2(-7) > 8
12 - 14 > 8
-2 > 8
FALSE!
-2 can not be greater than 8.
Hence, y = -2 does not make the inequality true.
For y = -3
substitute y = -3 in the inequality
3y² + 2(y - 5) > 8
3(-3)² + 2(-3 - 5) > 8
3(9) + 2(-8) > 8
27 - 16 > 8
11 > 8
TRUE!
11 is indeed greater than 8.
Hence, y = -3 MAKES the inequality TRUE.
Conclusion:
As y = -3 MAKES the inequality TRUE.
Therefore, option D i.e. y = -3 is true.

The distance traveled by a toy car can be modeled by D(t) = t3 − 3t2 + t − 3, where t > 3 represents time in seconds. If the car traveled for t − 3 seconds, identify the expression that represents the speed of the toy car.
Answer:
[tex]t^2+1[/tex]
Step-by-step explanation:
We are given that
Distance traveled by a toy car
[tex]D(t)=t^3-3t^2+t-3[/tex]
Where t>3
Time taken by car =t-3 seconds
We have to find the expression which represents the speed of the toy car.
We know that
[tex]Speed=\frac{Distance}{time}[/tex]
Using the formula
[tex]Speed=\frac{(t^3-3t^2+t-3)}{t-3}[/tex]
[tex]Speed=\frac{t^2(t-3)+(t-3)}{t-3}[/tex]
[tex]Speed=\frac{(t-3)(t^2+1)}{t-3}[/tex]
[tex]Speed=t^2+1[/tex]
Hence, the expression which represents the speed of the toy car
[tex]t^2+1[/tex]
The expression that represents the speed of the toy car is [tex]t^2 + 1[/tex].
The calculation is as follows:Given that,
The distance traveled should be [tex]D(t) = t^3 - 3t^2 + t - 3[/tex]
Here t>3
Time taken by car = t -3 seconds
Now the expression should be
[tex]Speed = Distance \div time\\\\= ( t^3 - 3t^2 + t - 3) \div (t - 3)\\\\= t^2(t - 3) + (t - 3) \div (t - 3)\\\\= (t - 3) (t^2 + 1) \div (t - 3)\\\\= t^2 + 1[/tex]

What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
The graph shows the value in the account after 2005.
0 indicates the year 2005.
1, 2, ...... indicates 2006, 2007, etc.
A) The value in 2007 corresponds to value of 2, which is 124.44.
True statement.
B) From 2013-2015 means that x values from 8 to 10.
Value of money during 2013-2015 = 180 - 166.19 = 13.81
From 2005-2007 means that x values from 0 to 2.
Value of money during 2005-2007 = 124.44 - 113 = 11.44
So Value of money during 2013-2015 is greater than that of 2005-2007.
True statement.
C) To find the amount account gained per year, find slope.
Slope = Change in y coordinates / Change in x coordinates
Take two points on the line (0, 113) and (2, 124.44)
Slope = (124.44 - 113) / (2 - 0) = 5.72
Hence the account gains $5.72 every year.
True statement.
D) Clearly the function is linear since the graph is a straight line.
Hence this is not a exponential growth.
Hence D is the false statement.
