Answer:
4(x - 4) = 4x - 16
Step-by-step explanation:
4(x - A) = 4x - 16
4x - 4A = 4x - 16
Equating Constant terms (terms without x): -4A = -16
A = 4
Therefore , 4(x - 4) = 4x - 16
The answer is 4.
In order to find the answer, divide 4 from the each number on the right side. You pull the 4 out from 4x, and 4 from 16 to arrive at 4(x - 4).
Find the length of side x in simplest radical form with a rational denominator.

Answer:
[tex]\frac{9\sqrt{3} }{2}[/tex]
Step-by-step explanation:
since the triangle is a 30-60-90 triangle:
√3 : 2 = x : 9
=> 2x = 9 √3
=> x = [tex]\frac{9\sqrt{3} }{2}[/tex]
Determine the volume of the picture below.
Answer:

Answer:
V = 6825in
Step-by-step explanation:
V = Ah
h = 30 in
A= 1/2(a+b)h = 1/2 ( 13+22)13
= 1/2(35)(13)(30)
= 35 x 13 x 15

What is 36 1/2 of 146?
Answer:
This question is not worded well (textbook's fault, not yours) so there are two possible answers.
5329 or 1/4.
Step-by-step explanation:
If it means 146 36.5 times; then 36.5 • 146 = 5329 .
But if it means 36.5 out of (over) 146; then 36.5 ÷ 146 = 1/4 (aka 0.25)

Five percent of all blue ray players manufactured by a large electronics company are defective. A quality control inspector randomly selects three players from the production line. What is the probability that exactly one of these three blue ray players is defective
Answer:
0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.
Step-by-step explanation:
For each player, there are only two possible outcomes. Either it is defective, or it is not. The probability of a player being defective is independent of any other ray. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Five percent of all blue ray players manufactured by a large electronics company are defective.
This means that [tex]p = 0.05[/tex]
A quality control inspector randomly selects three players from the production line.
This means that [tex]n = 3[/tex]
What is the probability that exactly one of these three blue ray players is defective?
This is P(X = 1). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{3,1}.(0.05)^{1}.(0.95)^{2} = 0.1354[/tex]
0.1354 = 13.54% probability that exactly one of these three blue ray players is defective.

Consider the equation 5 – 3(2x – 7) = 12 – 5(x – 2). Is x = 2 a solution to this
equation? Is x = 4 a solution to this equation? Explain your reasoning in each case
Answer:
see below
Step-by-step explanation:
5 – 3(2x – 7) = 12 – 5(x – 2)
Substitute x=2
5 – 3(2*2 – 7) = 12 – 5(2 – 2)
5 – 3(-3) = 12 – 5(0)
5 - 3*(-3) = 12
5+9 = 12
14=12
This is false so it is not a solution
5 – 3(2x – 7) = 12 – 5(x – 2)
Substitute x=5
5 – 3(2*4 – 7) = 12 – 5(4 – 2)
5 – 3(8-7) = 12 – 5(2)
5 - 3*1 = 12-10
5-3 = 2
2=2
This is true so it is a solution

A tube-feeding formula is administered to a patient via Gastrostomy at 75
ml/hr. The formula contains 6.5% protein. How much protein will the patient
receive in the entire day, if the feeding must be held (stopped) for 2 hours
before and 2 hours after the administration of Dilantin twice a day?
39
Answer:
97.5ml protein
Step-by-step explanation:
20hr * 75ml/hr = 1500ml
1500ml * .065 = 97.5ml protein
The patient will receive 78 ml protein in the entire day.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Tube feeding formula = 75 ml/hr
Protein content = 6.5% of 75 ml/hr = 0.065*75 ml/hr
⇒ Protein content = 4.875 ml/hr
Now since, the feeding must be held (stopped) for 2 hours before and 2 hours after the administration of Dilantin twice a day
So, Stoppage total hours = 2(2 + 2) = 2*4
⇒ Stoppage total hours = 8
Thus, total hours in a day when formula is feed = 24 - 8 = 16 hours
Thus Protein received by patient = 16hr * 4.875 ml/hr
⇒ Protein received by patient = 78 ml
Thus, the patient will receive 78 ml protein in the entire day.

At the start of the day, Megan has the following items for sale:
60 Sandwiches £2.40
40 Baguettes a £2.70
25 Jacket potatoes £3.25
She sells all the jacket potatoes, 65% of the sandwiches and 85% of the
baguettes.
What is the total value of her sales that day?
Answer:
266.65
Step-by-step explanation:
65% of 60 = 39 sandwiches sold
85% of 40 = 34 baguettes sold
all Jacket potatoes sold 3.25 x 25
34 x 2.70
39 x 2.40
add the total and comes to 266.65
There are 1,444 souvenir paperweights that need to be packed in boxes. Each box will hold 15 paperweights. How many boxes will be needed
Answer:96.267
Step-by-step explanation:
There are 1,444 paperweights and one box will hold 15 paperweights
So you will divide 1,444 by 15, which would give you 96.267
So you would need 96 boxes and an extra box, which won't be full holding 4 paper weights
In a sightseeing boat near the base of the Horseshoe Falls at Niagara Falls, a
passenger estimates the angle of elevation to the top of the falls to be 30°.
If the Horseshoe Falls are 173 feet high, what is the distance from the boat
to the base of the falls?
Answer:
299.64 ft
Step-by-step explanation:
The diagrammatic representation of the problem has been attached below :
Applying trigonometry :
We use the relation :
Tanθ = opposite / Adjacent
Tan 30 = 173 / d
0.5773502 = 173 / d
0.5773502d = 173
d = 173 / 0.5773502
d = 299.64 ft

Step-by-step explanation:
There are 25 muffins 9 are carrots so that would mean the equation would be 9/25. Since this is a percentage we would change 25 to 100 by multiplying by 4 and multiplying the top by 4 as well which will result in 36/100 or 36%.*hope this helps*
A landscaper needs to prepare 5 identical conical-shaped hanging planters by filling three-quarters of each planter with soil. If the diameter of each planter is 14 inches and the height is 28 inches, approximately how much soil is required for all the planters
Answer:
Amount of soil need = 5,331.255 inch³ (Approx.)
Step-by-step explanation:
Given;
Number of conical planters = 5
Volume used in each planter = 3/4
Diameter of planter = 14 inch
Height of planter = 28 inch
Find:
Amount of soil need
Computation:
Radius of planter = 14 /2
Radius of planter = 7 inch
Amount of soil need = [Number of conical planters][Volume used in each planter][Volume of each planter]
Amount of soil need = [5][3/4][(1/3)(π)(r²)(h)]
Amount of soil need = [5][0.75][(0.33)(3.14)(7²)(28)]
Amount of soil need = [5][0.75][(0.33)(3.14)(49)(28)]
Amount of soil need = [3.75][1,421.66]
Amount of soil need = 5,331.255 inch³ (Approx.)
