True or False: △XYZ has sides XY, YZ and XZ that measure 15 cm, 20 cm, and 25 cm respectively is a right triangle.
Please answer please
Answers
Answer:
True
Step-by-step explanation:
As a right triangle, it follows the Pathagorem Therom. All you have to do is multiply 15 x 15 = 225 and 20 x 20 = 400, then finally, you would do 25 x 25, which is the biggest number of all, and get 625. Since 225 + 400 = 625, this follows the Pathagorem Therom.

BRAINLY IF CORRECT!!!! Emmie has $60 to spend on craft supplies. The tax rate is 8.25%. What is the maximum amount she can spend on craft supplies before taxes?
Answers
Answer:
$55.42
Step-by-step explanation:
Price of supplies = 100%
Percentage of tax = 8.25%
Total percentage = 108.25%
Amount allowed to spend = $60
108.25% = 60
60 / 108.25 = .55427
0.55427x100 = 55.427

Find the Perimeter please explain 60 Point !!!!!
Answers
Answer:
The perimeter of the figure is approximately 42.85.
Step-by-step explanation:
Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is [tex]6\pi[/tex], or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.
-38d - 57 > -19d + 76
Answers
Answer:
d < -7
Step-by-step explanation:
-38d - 57 > -19d + 76
Add 19d to both sides
-19d - 57 > 76
Add 57 to both sides
-19d > 133
Divide both sides by -19
(when multiplying or dividing by a negative the inequality is reversed)
d < -7
Answer:
d < -7
Step-by-step explanation:
-38d - 57 > -19d +76
Add 19d and 57 to both sides
-19d > 133
Divide both sides by -19 (dividing by negative flips the inequality sign)
d < -7

The segments in each figure are tangent to the circle at the points shown.
Find each length.
Answers
Answer:
y = 12
Step-by-step explanation:
The segments are equal in length, SR = TR, so set up an equation:
[tex]\frac{y^2}{12}=y[/tex]
Multiply by 12.
[tex]y^2=12y\\y^2-12y=0[/tex]
Factor out the y on the left side.
[tex]y(y-12)=0[/tex]
There are two solutions: y = 0 and y = 12. The y = 0 solution makes no sence (segment SR can't have a length of 0). The other solution, y = 12, works just fine.

what is the value of x? i need the work for it as well thank you so much!
Answers
Answer:
x=19
Step-by-step explanation:
okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.
6x+4=118
subtract 4 from both sides
6x=114
divide by 6 on both sides
x=19

the diagram shows an isosceles triangle. all measurements are in cm.
3x-5 19-x

work out the perimeter of the triangle
Answers
Answer: 38
Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6
Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12
Two equal sides are 13 and base 12
Perimeter is 13 + 13 + 12 = 38 units
Answer is: 38
The perimeter of the given isosceles triangle is 38 cm.
What is the perimeter of an isosceles triangle?The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;
We can say that the perimeter of an isosceles triangle is:
P = 2a + b
where;
a = sides of the base anglesb = third side3x - 5 = 19 - x
3x + x = 19 + 5
4x = 24
x = 24/4
x = 6
The perimeter of the isosceles triangle is:
= 3x - 5 + 19 - x + 2x
= 3(6) - 5 + 19 - 6 + 2(6)
= 18 + 8 + 12
= 38 cm

Answer:
allen= y=3/2+2 billy= y= 3/2+4
Step-by-step explanation:
ok both of the equation are (almost) the same except for the y intercepts.
y=mx+b... you are learning about that hopefully!
so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.
if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.
as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross because billy's line is higher then allens, billy's tree will always be higher
