How many inches are in 4 1/2 feet ?
Answer:
54 in
Step-by-step explanation:
12 x 4= 48
1/2 ft= 6in
48 +6= 54
There are 54 inches in 4 1/2 feet.
We have,
To convert feet to inches, we know that 1 foot is equal to 12 inches.
To find the number of inches in 4 1/2 feet, we multiply the number of feet by 12 and add the number of inches.
4 feet multiplied by 12 inches/foot = 48 inches.
1/2 foot equals 1/2 multiplied by 12 inches/foot = 6 inches.
So,
4 1/2 feet is equal to 48 inches + 6 inches, which equals 54 inches.
Therefore,
There are 54 inches in 4 1/2 feet.

A household item uses 433 watts of electricity. This item is used for 34 hours each week. How much CO2 will be produced each week from this item
Answer:
CO₂ ( produced) = 6477,68 grs = 6,48 Kgs
Step-by-step explanation:
If the househoñd item uses 433 watts of electricity
In 1 hour will consume 433 wh or 0.433 Kwh
In 34 hours each week consumes 0,433* 34 will consume 14,722 Kwh
Considering that 1 Kwh produces between 430- 450 grs of CO₂
( we will take 440 grs per Kwh )
The CO₂ produced in a week for such device is 440* 14,722
CO₂ ( produced) = 6477,68 grs = 6,48 Kgs
Anita is years older than Basilio. Three times Anita's age added to six times Basilio's age is 36. 1. Define the variables 2. Create a system of equations. 3. Find the age of each person I
Answer :Anita's age = 7 years
Basilio's age = 2.5 years
Step 1. Assign variables to Anita's and Basilio's ages.
Anita's age = A
Basilio's age = B
Step 2. Use the information given to form two equations.
Anita is 4-1/2 years older than Basilio
A = 4.5 + B
Three times Anita's age added to six times Basilio's age is 36
3A + 6B = 36
Step 3. Substitute the value of A from first equation in to the second equation and solve for B
3(4.5 + B) + 6B = 36
13.5 + 3B + 6B = 36
13.5 + 9B = 36
9B = 36 - 13.5
9B = 22.5
B = 22.5/9 = 2.5
Step 4. Find the value of A
A = 4.5 + 2.5 = 7
Answer:
Anita's age = 7 years
Basilio's age = 2.5 years
The radius of a semicircle is 9 miles. What is the semicircle's perimeter?
Answer:
p = 9π + 18 miles Exact answer
p = 46.26 miles decimal approximation
Step-by-step explanation:
The whole circumference of a circle is
c = 2πr
Half a circle's circumference plus the diameter would be the semicircle's perimeter
p = (1/2)2πr + 2r
p = πr + 18
p = 9π + 18 miles Exact answer
p = 3.14 * 9 + 18
p = 46.26 miles decimal approximation

What are the sine, cosine, and tangent of Θ = 3 pi over 4 radians?
Answer:
StSin 135° = 0.7071
Cos 135° = - 0.7071.
Tan 135 = 1
Step-by-step explanation:
We are given that;
θ = 3π/4 rads
Now, 3π/4 in radius means that θ = 135°
Thus;
Sin 135° = 0.7071
Cos 135° = - 0.7071.
Tan 135 = sin 135/cos 134 = 1

Solve for angle A in the right triangle below, given that b = 2.5 and c = 6. (Note: Drawing is not necessarily to scale.)
9514 1404 393
Answer:
A ≈ 65.4°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the trig relations associated with pairs of sides. For angle A, given sides b and c are the adjacent side and the hypotenuse, respectively. The appropriate relation is ...
Cos = Adjacent/Hypotenuse
cos(A) = b/c
A = arccos(b/c) = arccos(2.5/6)
A ≈ 65.4°

To be eligible for financial aid, a student must earn no more than $15,000 per year. Use s to represent the yearly earnings (in dollars) of a student eligible for financial aid.
The required inequality for the student eligible for financial aid is s < $15,000 per year.
Given that,
To be eligible for financial aid, a student must earn no more than $15,000 per year. Use s to represent the yearly earnings (in dollars) of a student eligible for financial aid.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
According to the question value of s should be less than $15,000 in order for being a student eligible for financial aid.
So,
s < 15000
Thus, the required inequality for the student eligible for financial aid is s < $15,000 per year.

Answer:
1. shifts the graph right 2 units
2. y = -2(x -3)² +7
Step-by-step explanation:
1) Replacing x with x-h in any function shifts the graph h units to the right. Here, you have replaced x with (x-2), so the graph will be shifted 2 units to the right.
__
3) The vertex form of the equation of a parabola is ...
y = a(x -h)² +k . . . . . . . . for vertex (h, k) and vertical scale factor 'a'
Here, the vertex is (h, k) = (3, 7), and the parabola opens downward. This tells us the sign of 'a' is negative.
The graph is not so clear that it is easy to read the value of 'a' directly from it, but there are several clues.
The zeros of the above function are found at h±√(k/a). This graph shows the zeros to be located such that √(7/a) is slightly less than 2. This means the magnitude of 'a' will be slightly more than 7/2² = 1.75. The y-intercept of the function is 7-9a. It is less than -7, but probably more than -14. This puts bounds on 'a':
-14 < 7-9a < -7
-21/9 < -a < -14/9 ⇒ -2.33 < -a < -1.56
If we assume that 'a' is an integer value, we have bounded its magnitude as being between 1.75 and 2.33, so a=-2 is a reasonable choice.
The equation of the graph may be ...
y = -2(x -3)² +7
