Answer:
Acute Scalene Triangle
Step-by-step explanation:
This depends on the classification type. Because we are given both the angle measure and information on the sides, I am combining the angle and side classification.
1. In terms of angles, it's acute. All the angles are less than 90, so it makes it acute.
2. In terms of sides, it's scalene because it has no equal sides.
State the angle relationships for the following pairs of angles
Answer:
They are equal.
Step-by-step explanation:
Write the sequences equation for the table . Your equation should be in the form a(n)=man+b
Answer:
a(n) = 3.25n + 1.25Step-by-step explanation:
7.75-4,5 = 3.25
11-7.75 = 3.25
14.25-11 =3.25
17.5-14,25 = 3.25
It’s clear that this is an arithmetic sequence with common difference of 3.25
The equation form of such sequence is a(n) = a×n + b ,where ‘a’ is the common difference.
Then
a = 3.25
The first term a₁ = 4.5
On the other hand, a₁ = 3.25 ×(1) + b
Then
4.5 = 3.25 ×(1) + b
Then
b = 4.5 - 3.25 = 1.25
Conclusion:
a(n) = 3.25n + 1.25
2 3/10x-5/7y-4 5/6y-2 4/5x please help and simplify
Answer:
-1/2x -(5 23/42)y
Step-by-step explanation:
We assume you want to simplify the expression ...
(2 3/10)x -(5/7)y -(4 5/6)y -(2 4/5)x
__
The mixed numbers and fractions are combined in the usual way. A common denominator needs to be found for the addition or subtraction to take place.
= x(2 3/10 -2 4/5) -y(5/7 +4 5/6)
= x(23/10 -28/10) -y(30/42 +4 35/42)
= x(-5/10) -y(4 65/42)
= -1/2x -(5 23/42)y
Find the area of the shaded region. Express your answer in terms of \piπ and do not round any numbers.
Answer:
The strategy is to find out the total area and find the area of the 3 circles then subtract the sum of the circles' are from the total area
Total area = (length * width) = ( 3+6+9+12) * 18 = 540 sq. inch
3 Circles area = πr₁² + πr₂² + πr₃²
r₁= 12/2 = 6 in r₂ = 9/2 = 4.5 in r₃ = 6/2 = 3 inπr₁² + πr₂² + πr₃²
π(6²) + π(4.5)² + π(3)²
= 36π + 20.25π + 9π
= 65.25π
Shaded area = 540 - 64.25π = 335.011 sq. in

The equation of the line which passes through the point (3, 7) and has a gradient of 3 is:
Answer:
y = mx + b, where m is gradient and b is y-intercept
y = 3
y = 3x + b
To find b use the coordinate (3, 7) to find b
7 = 3(3) + b
b = 7 - 9
b = -2
Therefore, the equation will be:
Therefore, the equation will be:y = 3x - 2

please help i have to write and i dont understand
Answer:
A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.
B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:
5y-29=3y+19
Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.
C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.
Step-by-step explanation:
What is the measure of angle BOC, in degrees?
Answer:
The answer is 100 degrees.
Step-by-step explanation:
Step 1. Set up the equation 20x+25x=180
Step 2. Simplify to get 45x=180
Step 3. Divide 180 by 45 to get 4.
Step 4. Do 25x4 to get an answer of 100.

Question 9 of 10
If you shift the linear parent function, f(x) = x, down 7 units, what is the
equation of the new function?
A. g(x) = x
O B. g(x) = 7x
x
O c. g(x) = x - 7
D. g(x) = x+7
awnser
The correct answer is C. f(x) = x - 7
Step-by-step explanation:
In order to find this, you simply need to know that vertical shifts can be added on to the end of parent equations as constants. Since this is a downward shift, we use a negative number.

_____________________________________________
[tex] \tan(x) < 0 \: \: \: and \: \cos(x) < 0[/tex]
Thus :

[tex] \sin(x) = \frac{ \sqrt{16 \times 2} }{ \sqrt{9 \times 9} } \\ [/tex]
[tex] \sin(x) = \frac{4 \sqrt{2} }{9} \\ [/tex]

6 0, 6
e.
Answer:
Step-by-step explanation:
a, First arrange the data in ascending order:
77 79 80 81 84 84 86 88 92 95 <-- ten numbers.
Mean = sum of the numbers / 10
= 846/10
= 84.6.
The median is the middle number in the ordered list, or if there are an even number of values, the mean of the 2 middle numbers. There are 10 numbers here, so the median = (84+84)/2 = 84
Median = 84.
The mode is the value that occurs most. Here we have 2 84's so
Mode = 84.
Parts b to d are done in the same way as for the above, note if there is no mode write None.
For the stem leaf data first write out individual vales and then proceed as in a).
Values = 31 32 40 41 43 44 45 46 47 51 54 52 60 66

50 points please help
please explain your answer please ( such as formula n such )
Answer:
See below ~
Step-by-step explanation:
Part (a) :
Formula : Perimeter = 2 (Length + Width)⇒ 278 = 2(54 + Length)⇒ 139 = 54 + LengthLength = 139 - 54 = 85 mPart (b) :
Formula : Area = Length × Width⇒ 8811 = 99 x Width⇒ Width = 8811/99Width = 89 cmAnswer:
(a) The length is 85 m.
(b) The width is 89 cm.
Step-by-step explanation:
(a)
Perimeter (P) formula using the length (L) and width (W) of a rectangle.
P = 2L + 2W
P = 278 m
W = 54 m
278 = 2L + 2(54)
2L + 108 = 278
2L = 170
L = 85
Answer: The length is 85 m.
(b)
Area (A) formula using the length (L) and width (W) of a rectangle.
A = LW
A = 8811 cm²
L = 99 cm
8811 = 99 × W
W = 8811/99
W = 89
Answer: The width is 89 cm.
