Answer:
29
Step-by-step explanation:
substitute 5 where the w goes in the expression.
It should look like 4 • 5 + 9
Using the order of operations ( PEMDAS ) multiply 4 • 5 to get 20 and then add 9 to get 29
Using the order of operations ( PEMDAS ), the value of the expression is 29.
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
We need to find the value of the expression below when w = 5w = 5.
Using the order of operations ( PEMDAS ),
Then substitute 5 where the w goes in the expression.
4w+9 = 4 • 5 + 9
4w+9 = 20 + 9 = 29
Using the order of operations ( PEMDAS ), the value of the expression is 29.

The square has a side length of 10 ft and the circle inside the square has a diameter of 10 ft find the approximate area of the shaded region use 3.14 as an estimation for
Answer:
[tex]Area = 21.5ft^2[/tex]
Step-by-step explanation:
See attachment
Given
Square:
[tex]Length = 10ft[/tex]
Circle:
[tex]Diameter = 10ft[/tex]
[tex]\pi = 3.14[/tex]
Required: Calculate the area of the shaded region
First, calculate the area of the square:
[tex]A_1 = Length^2[/tex]
[tex]A_1 = (10ft)^2[/tex]
[tex]A_1 = 100ft^2[/tex]
Next, the area of the circle.
[tex]A_2 =\pi * \frac{d^2}{4}[/tex]
[tex]A_2 =3.14 * \frac{10^2}{4}[/tex]
[tex]A_2 =3.14 * \frac{100}{4}[/tex]
[tex]A_2 =3.14 * 25[/tex]
[tex]A_2 =78.5ft^2[/tex]
The shaded region has the following area
[tex]Area = A_1 - A_2[/tex]
i.e. the difference between the area of the square and the area of the circle
[tex]Area = 100ft^2 - 78.5ft^2[/tex]
[tex]Area = 21.5ft^2[/tex]

Step-by-step explanation:
-3 2^x + 3 = 2^(-3) + 3 = 0.125 + 3 = 3.125 (-3, 3.125)
-2 2^x + 3 = 2^(-2) + 3 = 0.25 + 3 = 3.25 (-2, 3.25)
-1 2^x + 3 = 2^(-1) + 3 = 0.5 + 3 = 3.5 (-1, 3.5)
0 2^x + 3 = 2^(0) + 3 = 1 + 3 = 4 (0, 4)
1 2^x + 3 = 2^(1) + 3 = 2 + 3 = 5 (1, 5)
2 2^x + 3 = 2^(2) + 3 = 4 + 3 = 12 (2, 12)
3 2^x + 3 = 2^(3) + 3 = 8 + 3 = 11 (3, 11)
A company produces fruity drinks that contain a percentage of real fruit juice. Drink
A contains 20% real fruit juice and Drink B contains 15% real fruit juice. The
company used 100.5 liters of real fruit juice to make 30 more liters of Drink A than
liters of Drink B. Write a system of equations that could be used to determine the
number of liters of Drink A made and the number of liters of Drink B made. Define
the variables that you use to write the system.
Answer:
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
Step-by-step explanation:
Let
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
1. The company used 100.5 liters of real fruit juice, then
2. Drink A:
x = amount of real fruit juice used
percentage of real fruit juice
Then
5x = amount of drink A produced
Drink B:
y = amount of real fruit juice used
percentage of real fruit juice
Then
amount of drink B produced
The company makes 30 more liters of Drink A than liters of Drink B, so

Matchsticks are used to make a sequence of
patterns:
3 , 5 , 7 ...
Find the nth term rule for the number of
matchsticks in pattern n
Answer:
Tn = 1 + 2n
Step-by-step explanation:
Given the arithmetic sequence
3 , 5 , 7 ...
The nth term of an AP is expressed as;
Tn = a + (n-1)d
a is the first term = 3
d is the common difference = 5-3 = 7-5 = 2
n is the number of terms
Substitute
Tn = 3 + (n-1)(2)
Tn = 3 + 2n-2
Tn = 1 + 2n
Hence the nth term rule for the number of matchsticks in pattern n is 1 + 2n

f(1)= -34
f(n)=f(n−1) - 3
Find an explicit formula for f(n).
Answer:
f(n) = -34 -3(n - 1)
Step-by-step explanation:
The explicit formula for f(n) is given below:
Given that
f(1)= -34
f(n)=f(n−1) - 3
Based on the above information
f(n) = a1 +d(n -1)
a1 = -34
d = -3
So
f(n) = -34 -3(n - 1)
This above represent an explicit formula
the average mark of three pupils are 68. what is the ratio of 5:4:3. how many marks did the best student get? HELP ME!
Answer:
85, 68, 51
Step-by-step explanation:
Average: The sum of all the numbers divided by the number of numbers
If the ratio of the scores is 5 : 4 : 3, let's just set it as 5x : 4x : 3x
Then using the definition of an average, we can write this equation.
(5x + 4x + 3x) / 3 = 68
Multiply both sides by 3.
5x + 4x + 3x = 68 * 3
Simplify.
12x = 204
x = 17
Now, substitute x = 17 into the original scores (5x, 4x, and 3x)
5x = 5 * 17 = 85
4x = 4 * 17 = 68
3x = 3 * 17 = 51
Just in case, let's check this answer. Find the average of the 3 test scores.
(85 + 68 + 51) / 3 =
204 / 3 = 68
Thus, the answers are correct

Last January, the average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and
several changes have been made to the cost of staying at the hotel.
• Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.
Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club.
. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.
How much should a customer expect to pay for a one-night stay if they are a member of the hotel's loyalty club and make
their reservation over the phone?
Answer:
$114.32
Step-by-step explanation:
Original Price: $132.52
increased: $34.65
Loyalty Club: -$57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
The amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77
What will be the amount?The average cost of a one-night stay at a hotel was $132.52. Since then, the hotel has changed ownership, and several changes have been made to the cost of staying at the hotel. Last summer, the new owners adjusted room prices so that the average cost of a one-night stay increased by $34.65.
Last December, the new owners offered a $57.80 per night discount to guests who belong to their loyalty club. Last week, the new owners introduced a service fee of $4.95 for any reservation made over the phone.
The price will be calculated as:-
Original Price: $132.52
increased: $34.65
Loyalty Club : - $57.80
Phone Fee: $4.95
You add all of them together, except for the Loyalty Club Fee. You subtract that fee by the total.
= 132.52 + 34.65 + 4.95 - 57.80 = $113.77
Therefore the amount of pay for a one-night stay, if they are a member of the hotel's loyalty club and make their reservation over the phone, will be $113.77.
