If Cordell has 6 nickels and 4 dimes, find the total
value of his dimes and nickels by substituting and
evaluating the expression 0.10d + 0.05n.
Answer: The correct answer is 0.70 total
Step-by-step explanation:
Use the expression 0.10d + 0.05n where
d = number of dimes (4)
n = number of nickels (6)
= 0.10 (4) + 0.05 (6)
= 0.40 + 0.30
total = 0.70

In the figure, angle D measures 71° and angle G measures 37°. What is the measurement of angle A?
Answer:
34 °
Step-by-step explanation:
∠D = 71°
∠G = 37°
In ΔGEF
Using angle sum property of triangle : Sum of all angles of triangle is 180°
∠G+∠E+∠F = 180°
Since ΔGEF is right angled triangle at F so, ∠F = 90°
Now, 37°+∠E+90° = 180°
127°+∠E= 180°
∠E= 180°-127° =53°
Now ∠E+∠D = 53°+71° = 124°
Now using exterior angle property in ΔABC
An exterior angle of a triangle is equal to the sum of the opposite interior angles
∠E+∠D is the exterior angle of ΔABC
So, ∠A+∠B = ∠E+∠D
since ΔABC is right angled triangle at B so, ∠B = 90°
∠A+90° = 124°
∠A = 124°-90°
∠A = 34°
Hence the measurement of angle A is 34 °
Assuming the following is a triangle, A = 72°
All interior angles of a triangle added together will always equal 180°, so \(180 - 71 - 37 = 72\)

The distance (d) in miles that Cecil runs depends on the number of track practices (p) he attends. D = 2p + 3 i) Solvetheequation d=2p+3forp. ii) How many practices he has to attended to run 13 miles?
Answer: i) \(p=\dfrac{d-3}{2}\)
ii) He has to attend 5 practices to run 13 miles.
Step-by-step explanation:
Given: The distance (d) in miles that Cecil runs depends on the number of track practices (p) he attends.
\(d=2p+3\)
i) To solve for p . first subtract 3 from both sides , we get
\(d-3=2p\)
Divide both sides by 2
\(\dfrac{d-3}{2}=p\)
So. \(p=\dfrac{d-3}{2}\)
ii) Put d= 13 , we get
\(p=\dfrac{13-3}{2}=\dfrac{10}{2}=5\)
i.e. he has to attend 5 practices to run 13 miles.
A cell phone company charges $60 a month for up to 1 gigabyte of data. The cost of additional data is $0.05 per megabyte. If d represents the number of additional megabytes used and c represents the total charges at the end of the month, which linear equation can be used to determine a user's monthly bill?
Answer:\(c=60+0.05d\)
Step-by-step explanation:
Given
Company charges \(\$60\) for \(1\ GB\) data
and charges \(\$0.05/MB\)
If c is the total cost and d represent no of additional megabyte then
Cost is given by the sum of fixed price + additional data charge
\(c=60+0.05\times d\)
Therefore final charge is given by
\(c=60+0.05d\)

Answer:
see explanation
Step-by-step explanation:
∠ AOB = 360° - 264° = 96°
The altitude OM bisects ∠ AOB and the base AB
(a)
∠ MOB = 0.5 × 96° = 48°
Using the cosine ratio in right triangle MOB
cos48° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{OM}{OB}\) = \(\frac{18}{r}\) ( OB is the radius r of the circle )
Multiply both sides by r
r × cos48° = 18 ( divide both sides by cos48° )
r = \(\frac{18}{cos48}\) ≈ 27 cm ( to the nearest cm )
(b)
Using the tangent ratio in the right triangle MOB
tan48° = \(\frac{opposite}{adjacent}\) = \(\frac{MB}{OM}\) = \(\frac{MB}{18}\) ( multiply both sides by 18 )
18 × tan48° = MB then
AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )

a rectangular prism has 711.68 cubic feet and its 4 feet long and 12.8 feet wide what's the height
\(w = 12.8 \: ft\)
\(l = 4 \: ft\)
\(v = 711.68 \: {ft}^{3} \)
To find:The height of the given rectangular prism.
Solution:\(v = lbh\)
\(12.8 \times 4 \times h = 711.68 \: {ft}^{3} \)
\(51.2 \times h = 711.68 \: {ft}^{3} \)
\(h = \frac{711.68}{51.2} \)
\(h = 13.9 \: ft\)
Therefore, the height of the given rectangular prism is 13.9 feets.

16) Avery selects two chips from a bag without looking at them. The bag has 5 green chips, 3 red chips, and 7 blue chips. What is the probability that he selects a red and then a blue chip (without replacing)? * 6 points 2/3 7/75 1/10 2/45
Answer: \(\dfrac{1}{10}\)
Step-by-step explanation:
Given: The bag has 5 green chips, 3 red chips, and 7 blue chips.
Total chips = 5+3+7= 15
Number of ways to select a red and then a blue chip = 3 x 7 = 21
Total number of ways to select 2 chips without replacement = 15 x 14 =210
Required probability = \(\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}\)
\(=\dfrac{21}{210}=\dfrac{1}{10}\)
So, the probability that he selects a red and then a blue chip (without replacing) = \(\dfrac{1}{10}\)
A company that makes barber scissors has found that the sales volume for barber scissors is directly proportional to the size of the sales force and inversely proportional to the price of the scissors. If 19440 pairs were sold in 2003, when there were 54 salespeople and the price was $20 a pair, what is the sales forecast for the upcoming year with 50 salespeople and a price of $18 a pair?
Answer:
20,000 pairs of barber scissors.
Step-by-step explanation:
The sales volume V for barber scissors is directly proportional to the size S of the sales force and inversely proportional to the price P of the scissors.
In other words, we can write that:
\(\displaystyle V = \frac{kS}{P}\)
Where k is the constant of proportionality.
19,440 pairs were sold in 2013, when there was 54 salespeople and the price was $20 a pair. Hence, V = 19440 when S = 54 and P = 20. Substitute and determine the value of k:
\(\displaystyle \begin{aligned} (19440) &= \frac{k(54)}{(20)} \\ \\ 19440 &= \frac{27}{10}k \\ \\ k &=\frac{10}{27}(19440) = 7200 \end{aligned}\)
Hence, our equation is:
\(\displaystyle V = \frac{7200S}{P}\)
We want to determine the sales forecast with 50 salespeople and a price of $18 a pair. Hence, S = 50 and P = 18:
\(\displaystyle \begin{aligned} V&= \frac{7200(50)}{(18)} \\ \\ &= 20000\end{aligned}\)
In conclusion, 20,000 pairs of barber scissors can be expected to be sold.
Is a hole in a function a discontinuity?
Yes, a hole in a function is considered a type of discontinuity. A hole occurs when a point is missing from the graph of a function, which causes the graph to have a break in it.
A discontinuity is a break or jump in the graph of a function. A hole in a function is a type of discontinuity where a point is missing from the graph, causing the graph to have a break in it. This type of discontinuity is usually caused by a function having a denominator that is equal to zero, as this creates an undefined point on the graph. This can also occur when two parts of the function are not connected, causing an open gap in the graph. In both cases, the graph is not continuous and has a discontinuity at the point where the hole is present.

Here we to identify is a hole in a function a discontinuity.
the term discontinuity is defined as is discontinuous at a point if it becomes undefined or the limit at that point does not exist. And whether this point is known as the point of discontinuity.
While we looking the hole on a graph looks like a hollow circle. And which represents the fact that the function approaches the point, here it is not actually defined on that precise value. Where the major reason why this function is not defined at is because is not in the domain of the function.
