Answer:
m = [tex]\frac{16}{3}[/tex] , z = [tex]\frac{24}{5}[/tex]
Step-by-step explanation:
Δ PQT and Δ PRS are similar ( by AA postulate ), so the ratios of corresponding sides are equal, that is
[tex]\frac{PQ}{PR}[/tex] = [tex]\frac{PT}{PS}[/tex] , substitute values
[tex]\frac{m-2}{m}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )
8(m - 2) = 5m ← distribute parenthesis on left side
8m - 16 = 5m ( subtract 5m from both sides )
3m - 16 = 0 ( add 16 to both sides )
3m = 16 ( divide both sides by 3 )
m = [tex]\frac{16}{3}[/tex]
and
[tex]\frac{QT}{RS}[/tex] = [tex]\frac{PT}{PS}[/tex] , substitute values
[tex]\frac{3}{z}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )
5z = 24 ( divide both sides by 5 )
z = [tex]\frac{24}{5}[/tex]

What two numbers add up to 16 and multiply to -36
Answer:
-2 and 18
Step-by-step explanation:
a + b = 16
ab = -36
a = (16-b)
b(16-b) = -36
16b - b² = -36
-b² + 16b + 36 = 0
b² - 16b - 36 = 0
(b+18)(b-2) = 0

Answer:
5. - 27.02
6. - 18.14
8. - 6.24
Step-by-step explanation:
Hello There!
Because each triangle is a right triangle we can solve for the missing side length using the Pythagorean Theorem
The Pythagorean theorem states that the sum of the two legs squared is equal to the hypotenuse squared
[tex]a^2+b^2=c^2[/tex]
For number 5 we are given two legs so all we have to do is plug in the values
[tex]17^2+21^2=c^2[/tex]
now we solve for c
[tex]17^2=289\\21^2=441\\441+289=730\\c^2=730\\\sqrt{c^2} =c\\\sqrt{730} =27.01851217[/tex]
we're left with c = 27.01851217
are final step is to round to the nearest hundredth
So we can conclude that the missing side length is equal to 27.02
For number 6 we are given the hypotenuse and a leg
So this time we use this equation
[tex]a^2=c^2-b^2[/tex]
where a^2 = missing leg
now we plug in the values and solve for a
[tex]a^2=27^2-20^2\\27^2=729\\20^2=400\\729=329\\a^2=329\\\sqrt{a^2} =a\\\sqrt{329} =18.13835715[/tex]
we're left with a = 18.13835715
our final step is to round to the nearest hundredth
So we can conclude that missing side length is equal to 18.14
For number 8 we are given the hypotenuse and a leg
so once again we use this equation:
[tex]b^2=c^2-a^2[/tex]
now we plug in the values and solve for x
[tex]b^2=8^2-5^2\\8^2=64\\5^2=25\\64-25=39\\b^2=39\\\sqrt{b^2} =b\\\sqrt{39} =6.244997998[/tex]
we're left with b = 6.244997998
our final step is to round to the nearest hundredth
so we can conclude that the missing side length is equal to 6.24

Step-by-step explanation:
The solution of the expression will be 3⁵/₁₂.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that the expression is 4¹/₄ - 5/6. The expression will be simplified as below,
E = 4¹/₄ - 5/6
First, simplify the mixed fraction part,
E = (17 / 4) - (5 / 6)
Solve the above equation by taking an LCM,
E = ( 102 - 20 ) / 24
E = 41 / 12
E = 3⁵/₁₂
Therefore, the expression after simplification will give the value 3⁵/₁₂.
