the second side of a triangular deck is 5 feet longer than the shortest side, and the third side is 5 feet shorter than twice the length of the shortest side. is the perimeter of the deck is 64 feet, what are the lengths of the three sides
Answers
The lengths of the three sides are 16 feet, 21 feet, and 27 feet
let the shortest side be x
then the second side would be x+ 5 feet
and the third side would be 2x- 5 feet
as we are provided with the parameter of the deck as 64 feet
Parameter = sum of all sides
64 = x + (x+5) + (2x-5)
64 = 4x
So, in order to find out the measurement of the sides of the triangular deck we need to solve this linear equation
64 = 4x
X = 64/4
X = 16 feet
Therefore, first side/ shortest side = x= 16 feet
Second side = x+5 = 16+5 = 21 feet
Third side = 2x-5= 2(16) -5 = 27feet

A bakery sold 138 mocha cupcakes in a day, which was 46% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answers
Answer:
x=300
Step-by-step explanation:
138=46%x
x=300
hope this helps!
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
46% = 138
100% = 300
The total number of cupcakes sold on that day is 300.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of mocha cupcakes sold in a day = 138
The percentage of mocha cupcakes sold in a day = 46%
The percentage of total cupcakes sold in a day = 100%
Now,
46% = 138
Multiply 100/46.
100/46 x 46% = 100/46 x 138
100% = 300
Thus,
The total number of cupcakes sold on that day is 300.

The solution to the given expression when evaluated would be expressed as: 3a + 4b³ - 5 = 3(6) + 4(2³) - 5 = 45.
How to Evaluate an Expression?To evaluate the expression, 3a + 4b³ - 5, when a = 6 and b = 2, substitute the values of a and b into the expression and solve.
Thus, we would have:
3a + 4b³ - 5 = 3(6) + 4(2³) - 5
Solve the exponent
3a + 4b³ - 5 = 3(6) + 4(8) - 5
3a + 4b³ - 5 = 18 + 32 - 5
Add
3a + 4b³ - 5 = 45

Determine whether each relation is a function. {(3, 2), (-1, 3), (5, 2)} and {(9, -1), (3, 6), (-2, 4), (3, 0)}

We can state that the given relations:
{(3, 2), (-1, 3), (5, 2)} is a function.
{(9, -1), (3, 6), (-2, 4), (3, 0)} is not a function.
What Makes a Relation a Function?A relation is a function if each of the x-values in the relation has exactly one corresponding y-value it is related to.
Given the relation with the ordered pairs, {(3, 2), (-1, 3), (5, 2)}, we can see that each x-value has exactly one y-value.
For the relation, {(9, -1), (3, 6), (-2, 4), (3, 0)}, we can observe that the x-value "3" has three corresponding y-values, "6, and 0", therefore, it is not function.

Fadi set out at 5am on his bike averaging at 6mph. At 8am Chris goes out on his moped averaging 15mph. What time will Chris catch up with Fadi?
Answers
Since at 8am Chris goes out on his moped averaging 15mph, the time Chris catches up with Fadi is at 10 am.
How to find the time will Chris catch up with Fadi?Since Fadi set out at 5am on his bike averaging at 6mph, the distance Fadi travels is d = vt where
v = Fadi's speed = 6 mph and t = time.So, Fadi's distance d = vt
= 6t
Now, At 8am Chris goes out on his moped averaging 15mph, the distance Chris travels is D = v't' where
v = Chris' speed and t = Chris' time of travel.So, Chris' distance D = v't'
= 15t'
Also, since Fadl sets out at 5 am on his bike and Chris goes out on his moped at 8 am, Chris sets out 8 am - 5 am = 3 hrs later.
So, Chris' time of travel t' = t - 3
So, Chris' distance D = 15t' = 15(t - 3)
Now, Chris will catch up with Fadi when they both cover the same distance
So, d = D
6t = 15(t - 3)
6t = 15t - 45
6t - 15t = -45
-9t = -45
t = -45/-9
t = 5 hours
Since Chris's time is t' = t - 3, substituting t = 5 into the equation, we have
t' = 5 - 3
= 2 hours
So, Chris catches up with Fadi 2 hours later at 8 am + 2 hours = 10 am.
So, the time Chris catches up with Fadi is at 10 am.

The 12th term in the sequence is -26.
Given,
B (n) = -4 – 2(n – 1)
We have to find the 12th term in the sequence:
To find the nth term in an arithmetic sequence:
An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.
Here,
First term, a = -4
Common difference, d = -2
nth term = 12
Now, let’s find 12th term
B(n) = -4 -2(n – 1)
B(12) = -4 – 2(12 – 1)
B(12) = -4 -2(11)
B(12) = -4 -22
B(12) = -26
That is, the 12th term in the sequence is -26.

Using function concepts, it is found that:
a) Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.
b) If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.
c) if f(x) = 2, x = 16, so point (16,2) is on the graph of f.
d) The domain is all real numbers except x = 4.
e) The x-intercept is of x = -8.
f) The y-intercept is of y = -2.
What are the points on the graph?The function is given by:
f(x) = (x + 8)/(x - 4).
Hence, when x = 3:
f(3) = (3 + 8)/(3 - 4) = 11/-1 = -11.
Hence:
Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.
When x = 1, we have that:
f(1) = (1 + 8)/(1 - 4) = 9/-3 = -3.
If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.
For f(x) = 2, we have that:
2 = (x + 8)/(x - 4)
2x - 8 = x + 8
x = 16.
Hence:
if f(x) = 2, x = 16, so point (16,2) is on the graph of f.
What is the domain of the function?The domain of a function is the set that contains all possible input values of the function.
This function is a fraction, meaning that the denominator cannot be zero, so:
x - 4 = 0 -> x = 4.
Hence:
The domain is all real numbers except x = 4.
What are the intercepts of the function?The x-intercept of a function is given by the value of x when f(x) = 0, that is, the value of x when the function crosses the x-axis.The y-intercept of a function is given by the value of f(x) when x = 0, that is, the value of y when the function crosses the y-axis.For this problem, we have that:
f(x) = 0.
(x + 8)/(x - 4) = 0.
x + 8 = 0
x = -8.
f(0) = 8/-4 = -2.
Hence:
e) The x-intercept is of x = -8.
f) The y-intercept is of y = -2.
