Answer:
180m²
Step-by-step explanation:
In order to solve this question, we have to find the area of the pyramid with a pentagonal base.
This pyramid has slant height = 24m
Since the base is a pentagon, it means it is 5 sided.
Each side of the base = 3m
The area of the pyramid = 1/2 × 5(side length) × slant height
= 1/2 × 5(3) × 24
= 180m²
Therefore, the square meters of metal needed to cover the faces of the pyramid = 180m²

Answer:
false
Step-by-step explanation:
because any number with power "0" always gives 1
Answer:
False
Step-by-step explanation:
[tex]x \in \mathbb{Q}[/tex]
[tex]x \cdot 0=x[/tex]
This statement is false.
Take the example:
[tex]$\frac{1}{2} \cdot 0\neq \frac{1}{2} $[/tex]
[tex]$\frac{1}{2} \cdot 0=0$[/tex]
The product of any number and 0 is 0.
The graphic organizer represents the sets of all rational numbers. What could be the value of A
Answer:
The correct option is;
B) 0
Step-by-step explanation:
Under the set of all rational numbers, there is the set of integers, which is a subset the set of rational numbers. Within the set of integers we have the set of whole numbers which is a direct subset of the set of integers. Within the set of whole numbers there is the set of natural numbers which is a direct subset of the set of whole numbers
Natural numbers are the numbers with which ordering and counting is made consisting of only positive whole number which according to ISO 80000-2 begin with 0, to give the natural numbers as 0, 1, 2, 3, .....

Tally Lake is 11.25 miles long. Mary starts at one end and kayaks toward the other end, paddling at a constant rate of 2.5 miles per hour. At the same time, Ann starts out from the opposite end and paddles toward Mary at a constant rate of 2 miles per hour. How long will it take for the girls to meet?
Answer:
2 and a half hours
Step-by-step explanation:
Hello!
To find this we add how far Mary and Ann travel and subtract that from the total distance till we get 0
2.5 + 2 = 4.5
11.25 - 4.5 = 6.75 First hour
6.75 - 4.5 = 2.25 Second hour
2.25 is half of 4.5 and half an hour is 30 minutes
2.25 -2.25 = 0 half hour
It will take them 2 and a half hours
The answer is 2 and a half hours

Amelia and Joey decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Amelia went first and landed 3 arrows in the outer ring and 3 arrows in the bull's-eye, for a total of 267 points. Joey went second and got 4 arrows in the outer ring and 3 arrows in the bull's-eye, earning a total of 281 points. How many points is each region of the target worth? The outer ring is worth ____ points, and the bull's-eye is worth ____ points.
Answer:
outer ring worth 14 pts
bull's-eye worth 74.333333 pts
Step-by-step explanation:
let the worth point of landing an arrow on the outer ring be "x" and on bull's eye be "y"
For amelia
[tex]3x + 3y = 267[/tex]
For joey
[tex]4x + 3y = 281[/tex]
subtracting the first equation from the second
[tex]x = 14[/tex]
[tex]3x + 3y = 267[/tex]
[tex]42 + 3y = 267[/tex]
[tex]3y = 223[/tex]

Find the longest side of a parallelogram with a perimeter of 66ft., If the sides measure 3x + 1 and 2x - 3.
Find the longest side of a parallelogram.
Formula used:-Perimeter of parallelogram = 2 ( a + b )
Solution:-We know that,
Perimeter of parallelogram = 2 ( a + b )
★ Substituting the values in the above formula,we get:
⇒ 66 = 2 ( 3x + 1 + 2x - 3 )
⇒ 66 = 2 ( 5x - 2 )
⇒ 66/2 = 5x - 2
⇒ 33 = 5x - 2
⇒ 5x - 2 = 33
⇒ 5x = 33 + 2
⇒ 5x = 35
⇒ x = 35/5
⇒ x = 7 ft
Now,
One side,a = 3x + 1
★ Putting the value of x
⇒ 3 × 7 + 1
⇒ 21 + 1
⇒ 22 ft
Other side,b = 2x - 3
★ Putting the value of x
⇒ 2 × 7 - 3
⇒ 14 - 3
⇒ 11 ft
Hence,the longest Side of given parallelogram is 22 ft ( 3x + 1 ) .

Write a problem based on the given information.
P = Cost of dinner
0.15p = cost of a 15% tip
P + 0.15p = 23
Answer:
The cost of dinner plus a 15% tip was $23. How much is the dinner?
the cost of the dinner = $20
Step-by-step explanation:
Given that:
p= cost of dinner
0.15p = cost of a 15% tip
p + 0.15 p = 23
The objective is to represent this problem in words based on the given information.
From above, we can say that:
The cost of dinner plus a 15% tip was $23. How much is the dinner?
SO;
p + 0.15 p = 23
1.15 p = 23
Divide both sides by 1.15
p = 23/1.15
p = 20
Therefore, the cost of the dinner = $20
A farmer takes 8 days to cultivate a plot of land i ha in area. What area
of land will he cultivate in 20 days working at the same rate?
The farmer took 8 days to cultivate one and a half hectares (15000 m^2)
so now divide 15000/8 which equals to 1875. so now we know that it takes him one day to cultivate 1875 m^2 which is 0.1875 hectares.
20 days = 0.1875 x 20
= 3.7500 hectares

The sum of two numbers is 6, their difference is 4, find the two numbers. What is their product?
Help as soon as possible. Thanks <3
Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5

7n +9 = -1+6(n+4)
can someone walk me through this please?
Answer:
n = 14
Step-by-step explanation:
7n +9 = -1+6(n+4)
Distribute
7n+9 = -1 +6n+24
Combine like terms
7n +9 = 6n +23
Subtract 6n from each side
7n -6n+9 = 6n-6n +23
n+9 = 23
Subtract 9 from each side
n+9-9=23-9
n = 14

Step-by-step explanation:
x cos θ + y sin θ = x cos β + y sin β
Let's say x = cos A, and y = sin A.
cos A cos θ + sin A sin θ = cos A cos β + sin A sin β
Use angle sum formula.
cos(A − θ) = cos(A − β)
A − θ = ±(A − β)
A − θ = β − A
2A = θ + β
A = (θ + β) / 2
cot A = cot((θ + β) / 2)
x/y = cot((θ + β) / 2)
Take a look at the explanation below. It proves that 'x / y = cot(θ + β / 2)' using a different method.

First of all, the bracket will be solved as per the BODMAS rule.
The bracket term is:
[tex]4(x-5)[/tex]
Now, 4 will be multiplied with [tex]x[/tex] and -5.
i.e.
[tex]4(x-5)=(4\times x-4\times 5)\\\Rightarrow (4x-20)[/tex]
Now, let us put the value back in the original expression.
[tex]13 - 4(x - 5) = 13-(4x-20)[/tex]
Now, let us remove the bracket, negative sign will be multiplied with both i.e. [tex]4x[/tex] and -20

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The average rate of change in T(d) for the interval d = 4 and d = 10 is 0. Which statement must be true?
Options :
a. The same number of tickets was sold on the fourth day and tenth day.
b. No tickets were sold on the fourth day and tenth day.
c. Fewer tickets were sold on the fourth day than on the tenth day.
d. More tickets were sold on the fourth day than on the tenth day.
Answer:
a. The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given that the average rate of change in T(d), a function used to relate the number of tickets sold for a movie to the number of days since its release is 0 for interval: d=4 and d=10.
Rate of change measures the change in quantity in relation to another, in the scenario it could be interpreted as, the change in quantity of ticket t sold with respect to change in the number of days since the movies was released.
Therefore, if the average rate of change obtained for d =4 and d = 10 gives 0, then it could be inferred that the value of T(d) on both days are the same.

Step-by-step explanation:
3/5 ⇒0.6
11/26⇒0.423
option a is wrong as
0.6 is not less than 0.432
option b is correct as
0.6 is greater than 0.4
option c is wrong as
0.6≠0.432
Let a be -1/6 and let b be 1/2. Let x be the sum of the reciprocals of a and b, let y be the product of the reciprocals of a and b, and let z be twice the reciprocal of a divided by the reciprocal of b. Calculate x+y+z. Please Help!
Answer:
x + y + z = - 22
Step-by-step explanation:
Reciprocal of a : - 6,
Reciprocal of b : 2
Therefore if x is the sum of the reciprocals of a and b, it will be - 6 + 2 = - 4. x will be - 4.
Respectively if y is the product of the reciprocals of a and b, it will be - 6 [tex]*[/tex] 2 = - 12. y is - 12. And if z is twice the reciprocal of a / the reciprocal of b, it will be the following,
z = 2(- 6) / 2
= - 12 / 2 = - 6
And x + y + z = - 4 - 12 - 6 = - 22. That is your solution.
