Answer:
[tex]3\sqrt{5}[/tex]
Step-by-step explanation:
Since the triangle has a right angle, we are going to use pythaogoran theoem, which is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
[tex]3^{2} +6^{2} =c^{2}[/tex]
9+36=c^2
45=c^2
[tex]\sqrt{45}[/tex]=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
[tex]\sqrt{9x5}[/tex]
Then take the sqr root of 9 and we have [tex]3\sqrt{5}[/tex]

Which of the following is equivalent to x4 - y4? Select all that apply.
(-y)(x + y)3
(x2 - y2)2
(x - y)2(x + y)2
O 62 - y2)(x2 + y2)
o 6-y)6+y)(x2+x2)
Answer: (x^2-y^2) (x^2+y^2) and (x-y)(x+y)(x^2+y^2)
Step-by-step explanation:
(x2 − y2) (x2 + y2)Expand (x2 − y2) (x2 + y2) using the FOIL Method.
Apply the distributive property.
x^2 (x^2 + y^2 ) − y^2 (x^2 + y )
Apply the distributive property.
x^2 x^2 +x^2 y^2 - y^2 (x^2 y^2 )
Apply the distributive property.
x^2 x^2 + x^2 y^2 - y^2 x^2- y^2 y^2
Combine the opposite terms in x^2 x^2 + x^2 y^2 - y^2 x^2 - y^2 y^2.
Reorder the factors in the terms x^2 y^2 and − x^2 y^2.
x^2 x^2+ x^2 y^2 - x^2 y^2 - y^2 y^2
Subtract 2 2 from 2 2.
x^2 x^2+ 0 - y^2 y^2
Add 2 2 and 0.
x2 x2- y2 y2
Simplify each term.
Multiply x2 by x2 by adding the exponents.
x^4 − y^2y^2
x^4 − y^4
(x-y)(x+y)(x^2+y^2)(x − y) (x + y) (x^2 + y^2)
Expand (x − y) (x + y) using the FOIL Method.
(x ⋅ x + xy − yx − y ⋅ y) (x^2 + y^2)
Combine the opposite terms in x ⋅ x + xy − yx − y ⋅ y.
(x ⋅ x − y ⋅ y) (x^2 + y^2)
(x^2 − y^2) (x^2 + y^2)
Expand (x^2 − y^2) (x^2 + y^2) using the FOIL Method.
Apply the distributive property.
x^2 (x^2 + y^2) − y^2 (x^2 + y^2)
Apply the distributive property.
x^2 x^2 + x^2y^2 - y^2 (x^2 + y^2)
Apply the distributive property.
x^2 x^2 + x^2 y^2 - y^2 x^2 - y^2 y ^2
Combine the opposite terms in x^2x^2 + x^2y^2 − y^2x^2 − y^2y^2.
x^2x^2 − y^2y^2
x^4 − y^4

Pia printed 2 maps of a walking trail. The length of the trail on the first map is 8 cm. The length of the trail on the second map is 6 cm.
A landmark on the first map is a triangle with length on the side of 3 mm, 4 mm, and 5 mm. What is the scale factor from the first map to the second map? What are the side lengths of the landmark on the second map? Show your work.
Will mark brainlyest if correct.
Answer: The scale factor from the first map to the second map is 4:3 (four to three) The side lengths of the landmark on the second map is 9/4 mm, 3 mm, 15/4mm.
Step-by-step explanation:
The scale factor is 8:6 which can be simplified to 4:3.
The side lengths of the landmark on the second map follows the same scale 4:3, so going in order:
4:3 = 3:x
4x = 9
x = 9/4
4:3 = 4:y
y = 3
4:3 = 5: z
4z = 15
z = 15/4
A pile of sand had a weight of 60kg.
The sand is out into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of sand in each bag
Answer:
Answer is 10:15:35
Step-by-step explanation:
Let the ratio be 2x,3x,7x
then according to question;
2x+3x+7x=60
12x=60
x=5
now put value of x in the ratios
2x=2x5
=10
3x=3x5
=15
7x=7x5
=35
thus,weight of three bags are 10:15:35

Answer:
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)=-2[/tex]
Hence, option B) is true.
Step-by-step explanation:
Given
g(t) = t² - 2
h(t) = t + 4
To determine
[tex]\left(g\:\circ \:\:h\right)\left(-4\right)=?[/tex]
Using the formula
[tex]\left(g\:\circ \:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)[/tex]
In order to determine g(h(-4)), first we need to determine h(-4), so
substituting t = -4 in h(t) = t + 4
h(t) = t + 4
h(-4) = -4 + 4
h(-4) = 0
so we can write
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)=g\left(0\right)[/tex]
now, to determine g(0), substitute t = 0 in g(t) = t² - 2v
g(t) = t² - 2
g(0) = (0)² - 2
g(0) = 0 - 2
g(0) = -2
so, finally we get
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)\:=g\left(h\left(-4\right)\right)=g\left(0\right)=-2[/tex]
Therefore,
[tex]\left(g\:\circ \:\:\:h\right)\left(-4\right)=-2[/tex]
Hence, option B) is true.

Answer:
MJK=90
MJL=63
JLK=63
KML=27
MNL=126
Step-by-step explanation:
If this is a perfect rectangle, then I should be correct:
Each angle of a rectangle is 90 degrees, so MJK is 90
Since we know angle KJL is 27, and MJK is 90, just subtract them to get 63.
Angle JLK should be equal to angle MJL so it is also 63
Angle KML should be equal to angle KJL so it would also be 27
And finally, angle JKN should be 27 so 27+27=54. And since all angles of a triangle add up to 180, you can get angle MNL by subtracting 180-54 to get 126 because angle MNL and JNK/KNJ are equal to each other
In a certain chemical, the ratio of zinc to copper is 4 to 11 . A jar of the chemical contains 308 grams of copper. How many grams of zinc does it contain?

Answer:
the fourth option: cannot be determined
Step-by-step explanation:
So the first option is the same as 21 times 9 which is more than 9, so it is incorrect.
The second option is the same as 2.3 times 21 and again its incorrect.
the third option
the fourth option has the same outcome because the fractions are equal.
therefore it cannot be determined

Terri wrote the system of linear inequalities.
-3x - 3y > -18
-X<-y
Select all of the ordered pairs that are part of the solution set for this system of linear inequalities.
(-1,5)
(2, 4)
(3, 3)
(4.6)
(5,2)
Answer:
Step-by-step explanation:
A,b,d
None of the ordered pairs is a solution to the system of linear inequalities.
The given system of inequalities is:
-3x - 3y > -18
-x<-y
From the inequality -3x - 3y > -18
-3(x + y) > -18
Multiply both sides by -1
3(x + y) < 18
Divide both sides by 3
x + y < 18/3
x + y < 6.......(*)
Also from the inequality -x < -y
Multiply both sides by -1
-1(-x) > -1(-y)
x > y...............(**)
Any ordered pair that is a solution to the system of linear inequalities must fulfil the inequalities in (*) and (**)
Since none of the ordered pairs given fulfill the conditions in (*) and (**), none of the given options is correct
