A chess piece is 15 centimeters tall, and its shadow is 13 centimeters long. How far away is the top of the chess piece from the end of its shadow? Round to the nearest tenth.
Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

HELP!!Extra Credit: Use trig ratios twice to find the value of x in the figure below: (Round to the nearest tenth)
500/650
х
41
Answer:
x = 73.8
Step-by-step explanation:
to find the blue line:
tan(50) = 41/a
a = 41/tan(50)
a = 34.4 to 1 decimal place
to find x:
tan(65) = x/34.4
x = 34.4tan(65)
x = 73.8 to 1 decimal place

36 = 2(4x-6)+12
36 = 8x - 12 +12
x = 36/8
=4.5
Answer:
Equation: 4x - 6 = 6 x = 3
Step-by-step explanation:
A rectangle is a parallelogram, which means that opposite sides are parallel. This means that both of the short sides equal 12. 12 plus 12 is 24, so substract 24 from 36 to get 12. This means that the sum of the long sides are 12; half of 12 is 6 so that is the length of one of the sides. This means that you can set the equation 4x - 6 equal to 6. Add 6 to both sides to get 4x = 12, then divide both sides by 4 to get x = 3. I think your equation should be 4x - 6 = 6, and x equals 3.
Sorry if I'm wrong, if I'm right then that picture of the rectangle is really misleading.
Answer A B C :) struggling a bit
Answer:
7ab
y³
e/f
Step-by-step explanation:
a*b*7= 7ab
y*y*y= y³
[tex]\frac{x^n}{x^y}=x^{n-y}\\\\\frac{e^3*f}{e^2*f^2}=\frac{e}{f}\\[/tex]
Answer:
a) 7ab
b) y^3
c) e/f
Step-by-step explanation:
a) when multiplying two variables, u can just put them right next to each other, e.g. b x c = bc
when numbers are added, same goes, they just go before the variable, hence the 7ab. If u had something like 7ab x 8 then you'd just multiply the 8 with the 7 and get 56ab
b) imagine y= 2. if u had 2 x 2 x 2, that would be 8 which is also 2^3. When any number is multiplied by itself n times, it's raised to that power. which is why y x y x y = y^3. y is being multiplied by itself 3 times.
c) If u had [tex]\frac{4*2}{2}[/tex], that would = 8/2 = 4 because it would simplify. in the fraction, you could also reduce the 2 since it appears in both the numerator and denominator.
same thing here: both the numerator and denominator have 2 e and 1 f so they get crossed out, leaving e/f
hope this helps!

Determine whether the ordered pair is a solution of the linear inequality.
y > x - 1 ordered pair (0, 1)
Help would be appreciated! (Will give brainliest) Please don’t give me invalid answers on purpose :(
Thanks!
Answer:
Yes, (0, 1) is the solution of the given inequality.
Step-by-step explanation:
To find whether the given ordered pair is a solution of the linear inequality, we will satisfy the inequality with the coordinates of the ordered pair.
If the inequality is true for the ordered pair it will be the solution.
Inequality is,
y > x - 1
For (0, 1),
1 > 0 - 1
1 > -1
True.
Therefore, ordered pair (0, 1) is the solution of the given inequality.
