Answer:
The height of the cuboid = 5 cm
Step-by-step explanation:
Explanation:-
Given that the volume of the cuboid = 40 cm³
Given that length of the cuboid (l) = 2 cm
Given that the width of the cuboid (w) = 4 cm
The volume of the cuboid is determined by
[tex]V = length X width X height[/tex]
40 = 2× 4× h
h = 5
The height of the cuboid = 5 cm
What is the value of X?

The number of sunflowers (s) in the garden is one more
than twice the number of roses (r):
is it inequality it not
what's its inequality model—×??
Answer:
s = 2r + 1
Step-by-step explanation:
Number of sunflower (s) is 1 more than twice the number of roses (r)
Mathematically ;
Number of sunflower = 1 + 2 * number of roses
Sunflower = s ; roses = r
s = 2r + 1
We want to study the relation between the number of sunflowers and roses, we will see that it is an equation and the equation is:
s = 2*r + 1
So we know that the number of sunflowers is one more than twice the number of roses, notice that it represents an equation (so it is not an inequality)
And the equation can be written as:
s = 2*r + 1
The number of sunflowers is 2 times the number of roses, plus 1.

The scatterplot for number of enrollments, N, in a sports club, t years after the
year 2006. The equation of the line of the best fit is N = 62t + 35. Find the residual
for the number of enrollments in year 2020 if the actual enrollment is 885
students.
Answer:
13.7 years
Step-by-step explanation:
The equation of the line of the best fit is N = 62t + 35
where
N is the number of enrollments
t is years after the year 2006
If the actual enrollment is 885 students. Put N = 885 in the given equation.
885 = 62t + 35
or
885 -35 = 62t
850 = 62t
t = 13.7 years
So, the required answer is 13.7 years.
Patrick is riding his bike on a rectangular path around his city.
There is a rest area at each of the path's four corners.
• The city map shows the corners marked with coordinates of (2, 2), (1, 2), (1, -2), and (-2,-2).
Each unit represents 2.5 miles.
What is the perimeter of the path, in miles?
With the given coordinates it doesn't form a rectangle the correct set of the coordinates should be (2, 2), (1, 2), (1, -2), and (2,-2).
Answer:
The perimeter of the given rectangle that is formed by the given coordinates is 30miles.
Step-by-step explanation:
We are given the Rectangular coordinates such as
(2,2) , (1,2) ,(1,-2) (2,-2)
we will mark these point on the cartesian planes to understand the rectangle
We can apply the distance formula or we can just look on the cartesian plane to simply get the distance between two points
we get
[(2,2) ,(1,2) ] and [(1,-2) ,(2,-2) ] are two units apart each pair as they are parallel so our width is
W = 2 units
similarly
we now need the length
(1,2) and (1,-2) are four units apart
so our length will be four units
L= 4 units
we need the perimeter
Perimeter of the rectangle = 2( L+W)
= 2( 2 + 4)
= 2* 6 = 12units
Now we are given that 1 unit is equal to 2.5 miles so 12 units will be
= 12* 2.5 = 30 miles
Therefore The perimeter of the given rectangle that is formed by the given coordinates is 30miles.

Q2. CQ3. AStep-by-step explanation:
Q2
Given is the horizontal line x = 2It has zero slope as vertical change (rise) is zeroCorrect option is CQ3
The line is proportional relationship y = kx
Using point (8, 40), we can find the value of k:
40 = 8kk = 40/8k = 5Roland earns $5 per hour
Correct option is A
What proportion can be used when there is a %, the word "is" and the "of" in a problem?
Answer:
C. is / of = % / 100Step-by-step explanation:
We can interpret this as:
x% of y is zCalculation is:
x*y/ 100 = zTranslate this into the given format:
% * of / 100 = is ⇒ % / 100 = is / ofThis matches option C
A farming community begins with one resident. Then every year, the number of residents multiplies by 10 Write an expression using an exponent to
represent the number of residents in the community after 5 years
Answer:
After 10 years , the number of residents in the community = 100,007.45
Step-by-step explanation:
Let P be the population of a farming community.
As we know that,
Exponential Growth model is :
P(t) = P₀[tex]e^{kt}[/tex] ........(1)
where P₀ is the initial state , k is the growth constant.
As given,
A farming community begins with one resident.
⇒At t = 0 , P(t) = 1
∴ Put t = 0 in equation (1), we get
1 = P₀[tex]e^{0}[/tex]
⇒1 = P₀
∴ equation (1) becomes
P(t) = [tex]e^{kt}[/tex] ......(2)
As given, every year, the number of residents multiplies by 10
⇒At t = 1 , P(t) = 10
∴ Put t = 1 in equation (2), we get
10 = [tex]e^{k}[/tex]
Taking ln both side we get
ln(10) = ln([tex]e^{k}[/tex] )
⇒2.3026 = k
∴ equation (2) becomes
P(t) = [tex]e^{2.3026t }[/tex]
Now, we have to find the population at t = 5
⇒P(5) = [tex]e^{5(2.3026} = e^{11.513} = 100,007.45[/tex]
So, we get
After 10 years , the number of residents in the community = 100,007.45

Lattice has £15000 in a savings account at the start of the year. How much will she have at the end of the year if the annual interest rate is 7.5%?
Answer:
£13 875
Step-by-step explanation:
first you have to find out how much is 7.5% of 15 000 and you find it by calculating 0,075 times 15 000 which becomes 1 125. then you take out that answer from your first answer which is 15 000 - 1 125= 13 875

a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are possible if letters and digits cannot be repeated?
Step-by-step explanation:
Choosing 4 digits out of 10 = 10C4 = 210.
Arranging the 4 digits in 4 places = 4!
Total number of ways to arrange digits
= 210 * 4! = 5040.
Choosing 2 letters out of 26 = 26C2 = 325
Arranging the 2 letters in 2 places = 2!
Total number of ways to arrange letters
= 325 * 2! = 650.
Total number of possible license plates
= 5040 * 650 = 3,276,000.
Answer:
3,276,000
Step-by-step explanation:
10 x 9 x 26 x 25 x 8 x 7 = 3,276,000
the numbers 10, 9, 8, 7 are the spaces available for a non-duplicated digit
the numbers 26 and 25 are for two non-duplicated letters
