Answer:
we are given
length =3 yards and 16 inches
now, we can change it in inches
we know that
1 yard =36 inches
so, we get
length =3*36 inches and 16 inches
length=124 inches
now, we will check each option
option-A:
we can see that this is also 124 inches
so, this is TRUE
option-B:
4 yd 4 in
we can change into inches
we know that
1 yard =36 inches
4 yd 4 in=4*36 inches +4 inch
4 yd 4 in=144 in
this is not equal to 124 in
so, this is FALSE
option-C:
3 yd 1 1/2 in
we know that
1 yard =36 inches
3 yd 1 1/2 in =
3 yd 1 1/2 in =
this is not same as 124 in
so, this is FALSE
option-D:
2 yd 52 in
we know that
1 yard =36 inches
2 yd 52 in
2 yd 52 in
so, this is same
so, this is TRUE
option-E:
10 ft 4 in
we know that
1 feet =12 inches
so,
10 ft 4 in=12*10 +4 in
10 ft 4 in=124 in
this is same
so, this is TRUE
Step-by-step explanation:
So yes 124 is the same as 3 yards and 16 inches
Hope this helps!!!
Work Shown:
1 foot = 12 inches
3 feet = 36 inches (multiply both sides by 3)
1 yard = 3 feet
1 yard = 36 inches (replace "3 ft" with "36 in")
3 yards = 108 inches (multiply both sides by 3)
3 yards, 16 inches = 3 yards + 16 inches
3 yards, 16 inches = 108 inches + 16 inches
3 yards, 16 inches = 124 inches

Vertex of graph located at (3,6)
What is vertex?A mathematical object's vertex is a special point where two or more lines or edges typically meet. Angles, polygons, and graphs are the most common examples of vertices.
Given equation f(x) = |x - 3| +6
after simplifying there will be two equations they are
y = x - 3 + 6 = x +3...….(1)
and y = -(x-3) +6
y = 9 - x...…(2)
substitute value of equation 2 in eq. 1
9 - x = x + 3
x = 3 and
substitute value of x in eq. 1
y = x + 3 =3 + 3
y = 6
x = 3, y = 6
Hence the intersecting points of both equation are (3,6)

Barnes and Nobles buys a book for $14.25. They markup the price of the book by 35%.
Answer:
$19.24
Step-by-step explanation:
Take 14.25 times 1.35.
The markup rate will be 35% when the cost of the book is $14.25 and sells for $19.237.
What is the markup rate?The markup rate is computed by dividing a unit's gross profit (its sales price less its cost to create or buy for resale) by its cost.
Barnes and Noble buy a book for $14.25. They mark up the price of the book by 35%.
As per the question, we have
cost = $14.25
markup rate = 35% = 0.35
Let's x represent markup for the book,
markup rate = markup/sale price × 100%
35% = x / $14.25
0.35 = x / $14.25
x = $14.25 × 0.35
Apply the multiplication operation, and we get
x = 4.9875
So sale price = markup + cost
So sale price = $4.9875 + $14.25
So sale price = $19.237
Thus, the markup rate will be 35% when the cost of the book is $14.25 and sells for $19.237.

A car can travel 480 miles on a full tank of petrol. The tank holds 60 litres. A driver fills the tank and sets off on a journey.How many litres of petrol will be left when the car has travelled 360 miles?
without calculator
Answer:
After travelling 360 miles, 15 litres of petrol will be left.
Step-by-step explanation:
If a car can travel 480 miles with a full tank of 60 liters of petrol, it could be said that each liter of petrol allows to travel 8 miles (480/60 = 8). Therefore, since the driver has driven his car for 360 miles, his tank has spent 45 liters of petrol (360/8 = 45). In conclusion, given that the tank has a capacity of 60 liters and that it was full at the time of departure, having spent 45 liters, 15 liters remain in the tank.

According to the given question.
We have a right angle triangle ABC.
In which
AB = 7
AC = 4
Now by Pythagoras Theorem
[tex]AB^{2} =AC^{2} +BC^{2}[/tex]
⇒ [tex](7)^{2} = (4)^{2} + BC^{2}[/tex]
⇒ [tex]49 = 16 +(BC)^{2}[/tex]
⇒ [tex]49 - 16=BC^{2}[/tex]
⇒ [tex]BC^{2} = 33[/tex]
⇒ [tex]BC=\sqrt{33}[/tex]
In the right angle triangle
Hypotenuse, AC = 7
The side BC is the adjacent side w.r.t angle θ.
And, Side BC is the opposite side w.r.t angle θ.
Therefore,
[tex]tan\theta=\frac{4 }{\sqrt{33} }[/tex]
[tex]cos\theta= \frac{\sqrt{33} }{7}[/tex]
[tex]sin\theta= \frac{4}{7}[/tex]

A rectangular playground is 40 feet wide. Find the area of this playground, if the fence around it, including the gates, is 200 feet long.
Answer:
[tex]A=2400ft[/tex]
Step-by-step explanation:
A rectangle is a closed planer quadrilateral with four right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:
[tex]Perimeter=w+h+w+h=2w+2h\\\\Where:\\\\w=Width\\h=Height[/tex]
The ectangular playground is 40 feet wide, so:
[tex]w=40ft[/tex]
Therefore:
[tex]Perimeter=2w+2h\\\\200=2(40)+2h\\\\200=80+2h[/tex]
Solving for h:
[tex]2h=200-80\\\\2h=120\\\\h=\frac{120}{2} \\\\h=60ft[/tex]
The area of a rectangle is equal to the product of two of its contiguous sides, hence:
[tex]A=wh\\\\A=(40)(60)=2400ft[/tex]

The answer to the volume of a sphere/hemisphere should only be written as a(n)
Answer:
Cubic unit.Step-by-step explanation:
The answer to the volume of a sphere/hemisphere should only be written a cubic unit, because volumes depends on three coordinates to be defined, width, lenght and height, where each coordinates is a length itselft, which multiplied give a cubic length unit, due to the power properties.
For example, imagine that you have all three dimensions in meters, then the product would be [tex]m \times m \times m=m^{3}[/tex].
Therefore, the answer that completes the statment is cubic unit. A volume should be always written in cubic units.
Answer:
The answer to the volume of a sphere/hemisphere should only be written as a function of the radius.
Step-by-step explanation:
An hemisphere is half of a sphere. Its volume can be determined by dividing the volume of a given sphere by 2. The volume is the maximum space or capacity that a 3 dimensional object occupies.
volume of a sphere = [tex]\frac{4}{3}[/tex] [tex]\pi[/tex] [tex]r^{3}[/tex]
volume of an hemisphere = [tex]\frac{2}{3}[/tex] [tex]\pi[/tex] [tex]r^{3}[/tex]
In both cases, the volume is dependent on the value of radius.
The answer to the volume of a sphere/hemisphere should only be written as a function of the radius. Volume is measured in cubic units.
There are 14math teachers and 26 science teachers at school today. What is the ratio of math teachers to math and science teachers at school?
It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.
Answer: 7: 13
The ratio would be 14: 26, however you are most likely asked to simplify it. Which is why the answer would be 7: 13

The quality control manager at a light bulb factory needs to estimate the mean life of a batch (population) of light bulbs. We assume that the population standard deviation is 100 hours. A random sample of 64 light bulbs from the batch yields a sample mean of 350. a) Construct a 95% confidence interval for the population mean of light bulbs in this batch. b) Do you think that the manufacturer has the right to state that the average life of the light bulbs is 400 hours
Answer:
a)95% confidence intervals for the population mean of light bulbs in this batch
(325.5 ,374.5)
b)
The calculated value Z = 4 > 1.96 at 0.05 level of significance
Null hypothesis is rejected
The manufacturer has not right to take the average life of the light bulbs is 400 hours.
Step-by-step explanation:
Given sample size n = 64
Given mean of the sample x⁻ = 350
Standard deviation of the Population σ = 100 hours
The tabulated value Z₀.₉₅ = 1.96
95% confidence intervals for the population mean of light bulbs in this batch
[tex](x^{-} - Z_{\frac{\alpha }{2} } \frac{S.D}{\sqrt{n} } , x^{-} + Z_{\frac{\alpha }{2} }\frac{S.D}{\sqrt{n} } )[/tex]

Determine the y-intercept of the function.
x = 4y - 6
Answer:
y = 3/2
Step-by-step explanation:
Answer:
x=4y-6
Geometric figure: Straight Line
Slope = 0.500/2.000 = 0.250
x-intercept = -6/1 = -6.00000
y-intercept = 6/4 = 3/2 = 1.50000
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x-(4*y-6)=0
Step by step solution :
Step 1 :
Equation of a Straight Line
1.1 Solve x-4y+6 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-4y+6 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3/2 so this line "cuts" the y axis at y= 1.50000
y-intercept = 6/4 = 3/2 = 1.50000
Calculate the X-Intercept :
When y = 0 the value of x is -6/1 Our line therefore "cuts" the x axis at x=-6.00000
x-intercept = -6/1 = -6.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.500 and for x=2.000, the value of y is 2.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 2.000 - 1.500 = 0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.500/2.000 = 0.250
Geometric figure: Straight Line
Slope = 0.500/2.000 = 0.250
x-intercept = -6/1 = -6.00000
y-intercept = 6/4 = 3/2 = 1.50000
Step-by-step explanation:
