Solve the equation for h and r. x= r-h/y
[tex]r \times x = \frac{r - h}{y} \\ [/tex]
Multiply sides by y
[tex]r \times x \times y = r - h[/tex]
Subtract sides minus r
[tex]r \times x \times y - r = - h[/tex]
Multiply sides by -1

In Mrs. Kee’s class there are 20 boys and 16 girls. 25% of her students wore a jacket to class. How many students wore a jacket to class?
Answer: 9
Step-by-step explanation: there are 36 students in total. Since 25% of students wore a jacket, you would multiply 36 by 1/4 which gets you 9, so 9 students wore jackets

Answer:
M=-1/4
Step-by-step explanation:
Use the slope intercept form y=mx+b to find the slope m.
Answer:
The slope of the equation: y=-1/4x+7 is -1/4
The slope of the equation: y=-3x+5 is -3
Step-by-step explanation:
It is easier to think of the slope at the number behind the x variable. But algebraically, y=mx+b is the formula and the number that is in the value of m is the slope of the linear function.

If two variables x and y are directly proportional, then as x rises, y will rise accordingly, and as x falls, y will fall accordingly. So, y=k x can be written.
The equation for k=y/x is k=b/p.

1. If the same 1.0 kg book is lifted 0.5 m above the table, but the table top is 1.0 m
above the floor, what would be the potential energy of the book if the reference level we
the floor?
Answer:
Potential Energy = 10J
Step-by-step explanation:
mass of the book = 1.0kg
height = (0.5 + 1)m
acceleration due to gravity = 10m/s²
Potential Energy = mass × acceleration × height
Potential Energy = 1kg × 10m/s² × 1m
Potential Energy = 10J
Samuel needs 332 feet of wood to build a fence. The wood comes in lengths of 15 feet.
How many total pieces of wood will Samuel need? Theresa needs twice as many feet of wood as Samuel. How many pieces of wood does Theresa need?
Answer:
23 and 45
Step-by-step explanation:
This is really just a simple division question. All we have to do to solve the first half is divide 332 by 15:
[tex]332 / 15 = 22.133333333[/tex]
We'll want to round that up to 23, because it seems they're asking for integers here.
For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:
[tex]22.13333333 *2 = 44.2666667[/tex]
Which rounded gives us 45.
Hope this helps!
Answer:
Samuel will need 23 pieces of wood.
Theresa will need 46 pieces of wood.
Step-by-step explanation:
To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:
[tex]332[/tex] ÷ [tex]15=22.1333[/tex]
Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.
Samuel will need 23 pieces of wood to build his fence.
_
If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):
[tex]23[/tex] × [tex]15=345[/tex]
Multiply [tex]345[/tex] by 2:
[tex]345[/tex] × [tex]2=690[/tex]
Now, divide [tex]690[/tex] by [tex]15[/tex]:
[tex]690[/tex] ÷ [tex]15[/tex]
[tex]=46[/tex]
Theresa will need 46 pieces of wood.

A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
C. All rotations take one half of the triangle to the other half of the triangle
D, it is a right triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
Answer:
c e f
Step-by-step explanation:
C. All rotations take one half of the triangle to the other half of the triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:
A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.
This means that:
All sides of the triangle must be the sameAll angles of the triangle must be the sameThe complete length of each side are rotated (not half).The above points imply that: options (a) and (b) are true

Now move points E and F around to change the orientation of the transversal. Be sure that point F does not cross and that point E does not cross . Do the relationships among the angles that you studied in questions 2 through 4 change when you change the transversal? If so, how?
Answer:
NO
Step-by-step explanation:
Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.
Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.
What are the interior angles about?When a transversal intersects two parallel lines, the same-side interior angles formed on the same side of the transversal are supplementary (their measures add up to 180 degrees). If the transversal or lines are altered and are not parallel, the supplementary relationship between same-side interior angles is no longer maintained.
In summary, these angle relationships only hold true specifically for parallel lines intersected by a transversal. If the transversal or the lines change, these angle relationships may no longer remain valid.
