Answer:9 /12 -4/12 = 5/12
Step-by-step explanation: First you need to find the same demointaor which can be 12 .You take 3/4 and times on boths side by 3 which gives you 9/12 .You take 1/3 and times on both sides by 4 which gives you 4/12. Now put 9 /12 and then put 4/12 and then subtract both which gives you 5/12.

Answer:
54 degrees
Step-by-step explanation:
The solution is : the area of ΔIJK is 11699 square centimeters.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°.
Find the area of ΔIJK, to the nearest square centimeter.
When given two sides of a triangle and an angle, the area of the triangle is calculated as:
1/2jksintheta
theta = 173°
Hence:
Area of triangle =
1/2 × 800 × 240 × sin 173
= 11699.456967 square centimeters
Approximately = 11699 square centimeters
Hence, The solution is : the area of ΔIJK is 11699 square centimeters.

Is the equation y=3x + 10 proportional? Explain how you know
Answers
Answer: Yes!
Step-by-step explanation:
If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality. ... It is a positive number.

Dalol depression is about 116 meters below sea
level. The top of mountain Dashin is about 4550
meters above sea level. What is the vertical
distance from the top of Dashin to the bottom of
Dalol depression?
Answers
Answer:
The vertical distance is 4,666 m
Step-by-step explanation:
The sea level is like a base
Heights above the sea level are considered positive
Heights below are regarded as negative
So the depression is at a height of -116 m
The mountain top is at a height of 4550 m
The vertical distance is thus;
4550 - (-116)
=
4550 + 116 = 4,666 m

question: Show that ABF is a right triangle.
Answers
Answer:
angle OAM and OBM are right angles because tangents form right angles with radii.
AO=BO and MA=MB
Quadrilateral MAOB =360 degrees
so angles AOB and AMB=90 degrees each
angle MBF=90 degrees
M is the midpoint of FA so MA=MF
MB=MF
Triangle MBF is a right triangle because angle BMF is 90 degrees and MB=MF
What's the sum of an infinite geometric series if the first term is 156 and the common ratio is 2∕3?
Answers
Answer:
468
Step-by-step explanation:
Formula for infinite sum of geometric series is;
S_∞ = a1/(1 - r)
Where;
a1 is first term
r is common ratio
We are given;
a1 = 156
r = ⅔
Thus;
S_∞ = 156/(1 - ⅔)
S_∞ = 156/(⅓)
S_∞ = 468

Answers
Answer:
A to B would be about 3 cm
Step-by-step explanation:
Step-by-step explanation:
Measure first the physical length of AB using a ruler then write it down like this:
LINE ¦ TRUE MEASURE ¦ RULER MEASURE
AB ¦ 4cm ¦ (write your ruler measurement)
BC ¦ 2.5cm ¦ (write here again)
CA ¦ x ¦ y
Solving for x:
CA² = 4² + 2.5² -2(4)(2.5)cos(75)
[tex]ca = \sqrt{16 + 6.25 - 20cos75} \\ = \sqrt{22.25 - 20cos75} \\ = 4.1320[/tex]
Solving for y:
[tex] \frac{ruler \: measure \: for \: 4cm}{4} = \frac{y}{4.1320} \\ 4y = 4.1320(ruler \: measure \: for \: 4cm) \\ y = 1.033 \times ruler \: measur \: for \: 4cm[/tex]
After you got all your measurements, use your protractor and measure 75° from left of B and with B as your center. Mark it and draw a line from B to the mark you just made for 75°.
From that line, draw the "ruler measure of 2.5cm." and the formed line would now be line BC.
Then, just connect the two endpoints (A and C)

What is the value of x that would make line a parallel to line b?
Answers
Answer:
B 16
Step-by-step explanation:
If you substitute in the values for x and input the value for b in both equations and solve you should get the same degree measure.
Input the vale for b which is 16substitute 16 for x (8(16) + 14)°Multiply 16 by 8 and you would get 128Then add 14 to 128 and you would get 142° for the measure of 1 angleThen do the same for the other equation to see if you get the same value:
substitute 16 for x (12(16) - 50)°Multiply 16 by 12 and you would get 192Then subtract 50 from 192 and you also should get 142°for the other angleSo the answer is B because when you input the value into both of the equations and solve, the measures of the angles are the same. The other values when you input them in the equations for x you get different angle measures.
