Answer:
A = 48.81°
Step-by-step explanation:
Angles in a Right Triangle
When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.
The tangent ratio is defined as:
[tex]\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
Opposite leg to angle A is 8 and adjacent leg is 7, thus:
[tex]\displaystyle \tan A=\frac{8}{7}[/tex]
Using the inverse tangent funcion:
[tex]\displaystyle A=\arctan\frac{8}{7}[/tex]
Calculating:
A = 48.81°
A taxi charges a flat fee of $3.00, plus an additional $1.25 per mile. Antonio can spend no more than $18. Choose the inequality that represents the number of miles he can ride, an describes the solution set.
Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles
Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤
and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.
20% of a number is 12.

Answer:
[C] 44°
Explanation:
That Is A Right Angle, So x° + 46° Needs To Equal 90°Equation: x + 46 = 90
Subtract 46 From Both Sides
x + 46 - 46 = 90 - 46
x = 44

The perimeter of the triangle below is 8x - 6.
Q
X + 1
P.
R
3x - 1
Which expression rrepresents the length of QR ?
helpppp
Answer:
QR = 4x - 6
Step-by-step explanation:
A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.
From the question:
Perimeter of triangle PQR = PQ + PR + QR
But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.
Therefore substituting gives:
8x - 6 = (x + 1) + (3x - 1) + QR
8x - 6 = (x + 3x + 1 - 1) + QR
8x - 6 = 4x + QR
QR = (8x - 6) - 4x
QR = 4x - 6
Simon makes a model of a boat, using a scale of 1 : 30
If the model has a height of 40 cm, find the height of the real boat.
Give your answer in metres.
Answer: 12 metres
Step-by-step explanation:
The scale factor used for the model is 1 : 30.
This means that for any 1cm on the model, the real boat would be 30 cm.
If the height is 40 cm on the model, the real boat will be 30 times that:
= 40 * 30
= 1,200 cm
A metre is equivalent to 100cm.
1,200 cm would therefore be:
= 1,200/100
= 12 metres

Mode ??
Median ??
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
Mode: no mode
No mode because there are no repeating numbers.
Median=7
Put in order from least to greatest- 1,6,7,42,81
Find the one in the middle- 7
In which quadrant does 694 lie?
Answer: C. quadrant l
Step-by-step explanation:
Angle 694° lies Quadrant IV which is correct option (D)
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values
What is the quadrant?A quadrant is defined as an area contained by the x and y axes, which there are four quadrants in a graph.
For Quadrant I : the value of x and y both are positive ( +,+ )
For Quadrant II : the value of x is negative and y is positive ( -,+ )
For Quadrant III : the value of x is negative and y is negative ( -, - )
For Quadrant IV : the value of x is positive and y is negative ( +, - )
Locate the quadrant of the angle.
If the angle is greater than 360°,
Subtract 360° until the angle is less than 360°.
⇒ 694 - 360
⇒ 334°
Hence, angle 694° lies Quadrant IV

What number is 56% of 400? Show ALL of your work.
Answer: 224
Step-by-step explanation:
56% is the same as saying (56/100). When finding a percent of a number, you’re really setting up a ratio with the value x:
(56/100)=(x/400)
Then you just cross multiply:
(56 x 400)/100=x
x=224

Answer:
Angle ABF is 120°.
Step-by-step explanation:
Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.
