Answer:
right angle ( right )
Step-by-step explanation:
Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not. In the triangle above, if a 2 < b 2 + c 2 the angle is acute.
The solution is :The Pythagorean Theorem ONLY works on the triangle is: right angle ( right )
Here, we have,
we know that,
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a^2 + b^2 = c^2.
so, we have,
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
The hypotenuse is the side of a triangle across from a right angle, so the Pythagorean theorem works for right triangles.
again,
we know that,
Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.
In the triangle above, if a 2 < b 2 + c 2 the angle is acute.
Hence, The solution is :The Pythagorean Theorem ONLY works on the triangle is: right angle ( right )

Answer:
y = 1/2x + 4
Step-by-step explanation:
y = mx + b
m is slope = 1/2
b is y-intercept = 4
how do you calculate the area of a circle with the diameter? what's the formula?
What's y=1/3x+1 -7x+8y-5
5
The slope-intercept form is y = m x + b y = m x + b , where m m is the slope and b b is the y-intercept. y = m x + b y = m x + b
Rewrite in slope-intercept form.
Subtract 3 x 3 x from both sides of the equation. − 8 y = 5- 3 x - 8 y = 5-3 x
Divide each term by −8 -8 and simplify. y = 3 x 8 − 58 y = 3 x 8 - 58
Rewrite in slope-intercept form. y = 38 x − 58 .

Step-by-step explanation:
A professional quarterback passed for 4,383 yards in 16 games in one football season. He wants to know his passing yardage per game, assuming he passed for the same number of yards each game.
If he passed for the same number of yards each game, how many yards did he pass for in each game?
plz help me.
The answer would be 273.9375, or 274 yards a game rounding up.
Use the equation r =2.1x^2 -14.3x +35, where x is the number of years after 2000, to determine the revenue from the sales of U.S. Recorded albums in the years 2000, 2001, 2002, 2003, 2005, 2010 and 2018. How would you describe the trend in the revenue from albums? To what do you attribute this?
Answer:
Step-by-step explanation:
Given that:
[tex]r = 2.1x^2 - 14.3x + 35[/tex]
For year 2000; x = 0
So; [tex]r (0) = 2.1(0)^2 - 14.3(0) + 35[/tex]
[tex]r (0) = 35[/tex]
For year 2001; x = 1
[tex]r (1) = 2.1(1)^2 - 14.3(1) + 35[/tex]
[tex]r (1) =22.8[/tex]
For year 2002; x = 2
[tex]r (2) = 2.1(2)^2 - 14.3(2) + 35[/tex]
[tex]r (2) = 14.8[/tex]
For year 2003; x = 3
[tex]r (3) = 2.1(3)^2 - 14.3(3) + 35[/tex]
[tex]r (3) = 11[/tex]
For year 2005; x = 5
[tex]r (5) = 2.1(5)^2 - 14.3(5) + 35[/tex]
r(5) = 16
For year 2010; x = 10
[tex]r (10) = 2.1(10)^2 - 14.3(10) + 35[/tex]
[tex]r(10) = 102[/tex]
For year 2018; x =18
[tex]r(18) = 2.1(18)^2 - 14.3 (18) + 35[/tex]
[tex]r(18) = 458[/tex]
Thus, the table can be presented as seen below.
Year 2000 2001 2002 2003 2005 2010 2018
x 0 1 2 3 5 10 18
r(x) 35 22.8 14.8 11 16 102 458
SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.
The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

Answer:
LM = 57
Step-by-step explanation:
For each median (JN, ML and KP), the distance from a vertex to the centroid is twice the distance from the centroid to the midpoint of the side opposite that vertex.
In that case, LQ = 2QM
If LQ = 38 then QM = 19
38 + 19 = 57
4a -3 = 2a +7
what's a?
Answer:
a =5
Step-by-step explanation:
4a -3 = 2a +7
Subtract 2a from each side
4a-2a -3 = 2a-2a +7
2a-3 =7
Add 3 to each side
2a-3+3 = 7+3
2a=10
Divide each side by 2
2a/2 = 10/2
a =5
Answer:
a=5
Step-by-step explanation:
4a-3+3=2a+7+3
4a=2a+10
4a-2a=2a+10-2a
2a=10
a=5

A man mixed 2 teaspoons of sugar into his large coffee but then added one more teaspoon of sugar because it was not sweet enough. What is the ratio of teaspoons of sugar to one large coffee
Answer:
the ratio of teaspoons of sugar to one large coffee is 3: 1
Step-by-step explanation:
The computation of the ratio of sugar teaspoons to one large coffee is as follows:
Sugar teaspoons = 2 + 1 = 3
And, the one large coffee = 1
So, based on the above information
The ratio between them is
= 3:1
= 3 to 1
hence, the ratio of teaspoons of sugar to one large coffee is 3: 1

Step-by-step explanation:
At the beginning of the year, Blake had $35 in savings and
saved an additional $16 each week thereafter. Zoe started
the year with $80 and saved $13 every week. Let B
represent the amount of money Blake has saved t weeks
after the beginning of the year and let Z represent the
amount of money Zoe has saved t weeks after the
beginning of the year. Write an equation for each
situation, in terms oft, and determine the number of
weeks after the beginning of the year until Blake and Zoe
have the same amount of money saved.
Answer:
B=35+16t
Z=80+13t
15 weeks
Step-by-step explanation:
Let's start by writing our equations
B=35+16t
Z=80+13t
To figure out when they have the same amount we can set the equations equal to each other and solve for t
so we have
35+16t=80+13t
Subtract 13t and 35 from both sides to get
3t=45
Divide by 3 to get t=15
-7(x+5) =21
apply the distributive property and simplify
Answer:
x=−8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(x+5)=21
(−7)(x)+(−7)(5)=21(Distribute)
−7x+−35=21
−7x−35=21
Step 2: Add 35 to both sides.
−7x−35+35=21+35
−7x=56
Step 3: Divide both sides by -7.
−7x/−7 = 56/−7
x=−8
Answer:-
Distributed: -7x+(-35)=21 Simplified: x=-8
Step-by-step explanation:-
Distributed:
-7(x+5)=21
(x*(-7))+(5*(-7))=21
-7x+(-35)=21
Simplified:
-7x-35=21
-7x=21+35
-7x=56
x=-8

reasons why meals in space is more complicated than preparing meals on earth.
Answer:
preparing food in space is complicated for many reasons some are microgravity, some foods are not perfected and some foods do not meet the requirements of space food. astronauts can't sprinkle salt and pepper on their food in space. They just float away because of microgravity.

write 0.87878787.... as a fraction
Step-by-step explanation:
To write 0.87878787 as a fraction you have to write 0.87878787 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.87878787 = 0.87878787/1 = 8.7878787/10 = 87.878787/100 = 878.78787/1000 = 8787.8787/10000 = 87878.787/100000 = 878787.87/1000000 = 8787878.7/10000000 = 87878787/100000000
And finally we have:
0.87878787 as a fraction equals 87878787/100000000
