Answer:A triangle is a three-sided figure whose angles always add up to 180°. Thus, ∠x +∠y + ∠z = 180°.
The largest angle of a triangle is opposite its longest side.
On the SAT, the triangle to the left would be referred to as triangle abc or ∆abc.
To find the perimeter of the triangle, add up all the sides (a + b + c).
To find the area of any triangle, use the formula, (1⁄2)bh. The height must be perpendicular to the base.
Two triangles are similar if their angles have the same measure. The triangles therefore have the same shape, and their sides will be in proportion.
Triangles are said to be congruent if they have the same shape and size.
Equilateral Triangles
Equilateral Triangle
An equilateral triangle has three equal sides. Thus: a = b = c.
An equilateral triangle has three angles are also equal. Thus, ∠x = ∠y = ∠z.
Since the angles of a triangle always add up to 180°, each angle of an equilateral triangle must also equal 60°. Thus, ∠x = ∠y = ∠z = 60°.

On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p.m.
At 12:15 p.m., the water in the pool was 45 inches deep.
At 12:35 p.m., the water in the pool was 41 inches deep.
Part A - By how many inches does the depth of the water decrease each minute?
Answer: Every ten minutes the water decreases by two, so you would divide 2/10, which would be 0.2, meaning the water decreases 0.2 inches per minute.
Answer:
so every 20 minutes it goes down by 4 inches so 20x-4y
Step-by-step explanation:
20x-4y means every 20 minutes it goes down 4 inches

kiran and clare live 24 mile away from each other along a rail trail. One Saturday the two friends started walking toward each other along a trail at 8:00 am with a plan to have a picnic when they meet if kiran walks 3 miles per hour while clare walks 3.4 miles per hour. At what time will the two friends meet and have their picnic
Answer:
11:45
Step-by-step explanation:
Total distance between Kiran and Clare is 24 miles. They started walking at 8.00 am.
Speed of Kiran is 3 miles/hr and speed of Clare is 3.4 miles/hr.
So the relative speed of them is,
miles/hr
Both the speed are added as they moving in opposite direction.
We know that,
i.e
Putting the values,
As they started at 8.00 am, so the time at which will meet will be,

The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below:
Step 1: 4(2x − 4) = 8 + 2x + 8
Step 2: 6x − 8 = 16 + 2x
Step 3: 6x − 2x = 16 + 8
Step 4: 4x = 24
Step 5: x = 6
In which step did the student first make an error and what is the correct step?
Step 2; 8x − 4 = 2(6 + x + 6)
Step 2; 8x − 16 = 16 + 2x
Step 3; 6x − 2x = 16 − 8
Step 3; 6x + 2x = 16 + 8

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she started filling it. Time (minutes) 1, 1.5, 2 Water (gallons) 16.50, 24.75,33. Now find the constant of proportionality (in gallons per minute) for the second and third rows of the table. Show your work.
Answer:
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute

Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)?
2.66 light-years
7.18 light-years
7.74 light-years
9.46 light-years
Answer:
7.18 light-years
Step-by-step explanation:
6.8 x 10^13 = 68,000,000,000,000
9.46 x10 ^12 = 9,460,000,000,000
6.8 x 10^13 * 1 light year / 9.46 x 10^12 = 7.188 light years.

apparently this is explains to find the linear function by the table ( given) but in slope intercept form ( please help me :') )
Answer:
y=4x+3.....hope this helps ; )
Step-by-step explanation:
Answer:
y = 4x +b
Step-by-step explanation:
The question asks you to write in slop intercept form which is y = mx+b so first you ahve to solve for the slope (m) and the formula for that is m = y2-y1/x2-x1
and bascially you plug in any points that are on the table and use the y's and x's
so im going to use the first two points
m = (11-7) / (2-1)
= 4 / 1
= 4
so the slope equals four and we can plug that into our slope intercept equation
y = 4x + b and now we need to slove for b the y intercept and we can do that by plugging in any points from the table into our equation (to understand why this works probaly ask you teacher for a in-depth explination)
im going to use the first points again and plug it into our equation
7 = 4(1) + b (mutiply 1 by four)
7 = 4 +b (isolate b so subtract four from each side)
-4 -4
3 = b so we now know the slope and the y intercept so our equation in slope intercept form will be y = 4x +3

Question: (10-2)+(5x293)+(82x90)-2938
Answer:
5915
Step-by-step explanation:
Ok, so in 5th grade, we were taught to use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), to get a long question correct. It has to be in that order, so start with parentheses. Here is the whole equation simplified: 8+1465+7380-2938. Now you will go from left to right. So, you have 1473+4442. And last, simplify, 1473+4442=5915. Hopefully this helped and if it did please mark it brainliest.
Answer:
5,915
Step-by-step explanation:
PEMDAS
P= Paranthesis:
(10-2)= 8
(5x293)=1,465
(82X90)=7,380
Then: AS add and subtract
8+1,465+7,380-2938=
5,915
