Answer:The new latitude is given by adding the 55° flown to the original latitude, which is 17° S, or -17°; this gives -17+55=38°.
Step-by-step explanation:The equator is taken as 0°, going north is positive and going south is negative. So 17° S should be taken as meaning -17°. Flying north 55° means I should add 55°. That gives the answer above.
A construction crew is lengthening a road. The road started with a length of 56 miles, and the crew is adding 4 miles to the road each day.
Let L represent the total length of the road in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then
use this equation to find the total length of the road after the crew has worked 34 days.
Equation:
D=
Total length of the road after 34 days: miles

When Sandy and Allen's mother decorates the house for a holiday by herself, it takes her 5 hours. When both Sandy and Allen help, the three can finish the job in 2.5 hours. When only Allen helps his mother decorate, it takes the two 3.5 hours. How long would it take Sandy to decorate the house by herself?
Answer:
8 3/4
Step-by-step explanation:
time for all work:
Mother - 5 hours
Mother + Sandy + Allen - 2.5 hours
Mother + Allen - 3.5 hours
Sandy - x
In 1 hour
Mother - 1/5
Mother + Sandy + Allen - 2/5
Mother + Allen - 2/7
Sandy - 1/x
(M+S+A) - S = (M+A)
2/5 - 1/x = 2/7
solve equation
x = 8 3/4 hours
Hope this helps :)
The number of hours that Sandy took to decorate the house by herself will be 8.75 hours.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
At the point when Sandy and Allen's mom designs the house for a vacation without help from anyone else, it requires her 5 hours. At the point when both Sandy and Allen help, the three can complete the task in 2.5 hours. At the point when just Allen assists his mom with finishing, it requires two 3.5 hours.
Let 'M', 'S', and 'A' be the number of hours of mother, Sandy, and Allen. Then the equations are given as,
M = 5 ...1
1/M + 1/S + 1/A = 1/2.5 ...2
1/M + 1/A = 1/3.5 ....3
From equations 2 and 3, then we have
1/3.5 + 1/S = 1/2.5
1/S = 1/2.5 - 1/3.5
1/S = 4 / 35
S = 35/ 4
S = 8.75 hours
The number of hours that Sandy took to decorate the house by herself will be 8.75 hours.

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people."
What percentage of its capacity is 84 people?
Answer:
112%
Step-by-step explanation:
The percentage of its capacity is calculated as
Number of people / Maximum Occupancy × 100%
Number of people = 84 people
Maximum Occupancy = 75 people
Hence:
84 people /75 people × 100
= 1.12 × 100
= 112%
Therefore, the percentage of its capacity that is 84 people is 112 %
Given: ΔABC, AB=12, m∠A=60°,m∠C=45°, AB =8 Find the perimeter of ΔABC
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
[tex]\frac{SinA}{a} = \frac{SinB}{b} = \frac{SinC}{c}[/tex]
∴ [tex]\frac{SinA}{a} = \frac{SinC}{c}[/tex]
In the diagram, [tex]a = /BC/[/tex] and [tex]c = /AB/ = 12[/tex]
m∠A=60° and m∠C=45°
∴ [tex]\frac{Sin60}{/BC/} = \frac{Sin45}{12}[/tex]
[tex]/BC/ = \frac{12 \times Sin60}{Sin45}[/tex]
[tex]/BC/ = 6\sqrt{6}[/tex]
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
[tex]\frac{SinB}{b} = \frac{SinC}{c}[/tex]
From the diagram, [tex]b = /AC/[/tex]
[tex]\frac{Sin75}{/AC/} = \frac{Sin45}{12}[/tex]
[tex]/AC/ = \frac{12 \times Sin75}{Sin45}[/tex]
[tex]/AC/ = 6 + 6\sqrt{3}[/tex]
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
= [tex]12 + 6\sqrt{6} + 6+6\sqrt{3}[/tex]
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
Answer:
Using the figure above, if AB = RT and ∠R = 70°, then ________.
ΔABC ~ ΔRTS
m ∠ S = 50°
ΔABC ≅ ΔRTS
m ∠ S = 60°

Answer:The answer is 14x-25=115 (B)
Step-by-step explanation:
he bought a certain amount of shirts, each being 14 dollars. So 14(how ever many shirts)- 25(the coupon) = Sales price
Answer:
b. 14x-25=115
Step-by-step explanation:
14 dollars each and 25 discount
the "each" here means the cost per cloth is 14, and total cost of the clothes Marco buy will increase depend on the amount of clothes.
Thus, it is 14x
The 25 discount represent that NO MATTER how many clothes Marco purchase, he only gets a discount of 25. It is a independent value.
Total clothes bought - discount = total amount of money spent.
Thus, it is 14x-25=115

If /is an explanatory variable and m is the corresponding response variable, which of these would be represented by the horizontal axis on a scatterplot? O A. Neither /nor m B. 1 C. m D. Both / and m??
Answer: The explanatory variable goes in the horizontal axis.
Step-by-step explanation:
The explanatory variable is the variable that can be manipulated in an experiment. This is also called (and more commonly) the independent variable. This is the variable we usually "input" in a system, with the objective of observing the change in the response variable (also called the dependent variable, because it depends on the independent variable).
Usually, we write the explanatory variable on the horizontal axis and the response variable on the y-axis.
Then the correct answer would be C: /.
This is only because m is defined ONLY as a response variable, there are a lot of experiments with two variables, where we can use each of the variables as the explanatory variable.
And also there are some cases where in order to make the graph easier to read, we do not use the explanatory variable in the horizontal axis, instead, we may use some transformation or something alike, but those are really special cases.

What is the equation of the line that passes through the point (4,−2) and has a slope of −2?
Answer:y=-2x+6
Step-by-step explanation:
You want to find the equation for a line that passes through the point (4,-2) and has a slope of -2.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -2. So you can right away fill in the equation for a line somewhat to read:
y=-2x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(4,-2). When x of the line is 4, y of the line must be -2.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the -2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-2).
So, why not plug in for x the number 4 and for y the number -2? This will allow us to solve for b for the particular line that passes through the point you gave!.
(4,-2). y=mx+b or -2=-2 × 4+b, or solving for b: b=-2-(-2)(4). b=6.

A, B, and C are pegs on the bank of a canal which has
parallel straight sides. C and D are directly opposite
each other. AB = 30 m and BC = 140 m.
When I walk from A directly away from the bank,
I reach a point E, 25 m from A, such that E, B, and
D line up. How wide is the canal?
Answer:
116.67 m
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are equal and the ratio of their sides are in the same proportion.
From the image attached:
∠A = ∠C = 90° (right angled triangle).
∠ABE = ∠CBD (vertically opposite angles are equal to each other)
The angle-angle similarity postulate states that If two angles of one triangle are equal to two angles of another triangle, then both triangles must be similar. Hence:
Since, ∠A = ∠C and ∠ABE = ∠CBD, we can say that ΔABE and ΔCBD are similar triangles. Since they are similar, the ratio of their corresponding sides is equal. Therefore:
BC / AB = CD / AE
BC = 140 m, AB = 30 m, AE = 25 m
substituting:
140 / 30 = CD / 25
CD = (140 / 30) * 25
CD = 116.67 m
The width of the canal = CD = 116.67 m
