Answer:
c = 19
Step-by-step explanation:
Let's rephrase this equation:
4(c-18) = 4
Let's plug in 19
4(19-18) = 4
19-18 = 1
4 multiplied by 1 is 4 so therefore, c = 19
Factor the following expression: 16z+20
Answer:

Answer:
4(4z + 5)
Step-by-step explanation:
Given
16z + 20 ← factor out 4 from each term
= 4(4z + 5) ← in factored form

PLEASE HELP! a. How many 7-digit numbers have odd numbers in the odd positions (i.e. odd numbers in the first, third, fifth and seventh positions)?
(2)
b. How many of these have even numbers in the even positions?
Answer:
a) 625,000
b) 78,125 if 0 is counted as even or 40,000 if it is not.
Step-by-step explanation:
Represent the 7 digit number by abcdefg
Position Allowable digits Number of allowable digits
g 1,3,5,7,9 5
f 0,1,2,3,4,5,6,7,8,9 10
e 1,3,5,7,9 5
d 0,1,2,3,4,5,6,7,8,9 10
c 1,3,5,7,9 5
b 0,1,2,3,4,5,6,7,8,9 10
a 1,3,5,7,9 5
This implies that the number of 7 digit numbers with odd digits in the odd positions is
5x10x5x10x5x10x5=625000
For part b, count 0 as an even digit. Then rule out 1,3,5,7,9 in positions b, d, and f. This leaves 5 possible digits in all 7 locations. So the answer is
5^7=78,125
If 0 is not counted as an even digit, then the answer is
4^3+5^4=40000
Which is the only center point that lies on the edge of a triangle?
the incenter of a right triangle
the incenter of an obtuse triangle
the circumcenter of a right triangle
the circumcenter of an obtuse triangle
Answer:
Circumcenter
Circumcenter is the only center point on the edge of a triangle. this is true in the case of the right-angle triangle. It exactly lies on the midpoint of the hypotenuse. Circumcenter is the point of intersection of the perpendicular bisector of sides of triangles.
The circumcenter of a right triangle is the only center point that lies on the edge of a triangle.
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
To find the only center point that lies on the edge of a triangle.
Now, We know that;
The circumcenter of a right triangle is the only center point that lies on the edge of a triangle.
Thus, The correct statement is,

Express the shaded area as a fraction, a decimal, and a percent of the whole.
Answer:
1/2
0.5
50%
Step-by-step explanation:
The square is spilt into 2 equal pieces, one out of the 2 is shaded therefore 1/2 is shaded. The decimal to represent the shaded area would be 0.5, as 1 times 1/2 = 0.5. As a percent the shaded area represents 50% as 1/2 times 100 (per cent = per hundred) is equivalent to 50.

write the equation of the line in fully simplified slope intercept form
Answer:
[tex] y = \dfrac{5}{2}x - 4 [/tex]
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
where m = slope, and b = y-intercept.
From the graph, we see that the y-intercept, b, is -4, so now we have
y = mx - 4
Now we need to find the slope from the graph.
We see that the points (0, -4), the y-intercept, and (2, 1) are points of the line.
slope = rise/run
rise is a vertical distance. (Up is positive; down is negative.)
run is a horizontal distance. (Right is positive; left is negative.)
Start at (0, -4). Go up 5 units. That is a rise of +5 since you went up. Now go 2 units to the right. That is a run of +2 units since you went right. The rise is 5, and the run is 2.
m = slope = rise/run = 5/2
The equation is
[tex] y = \dfrac{5}{2}x - 4 [/tex]

Prompt: Describe the similarities and differences of the properties of squares, rectangles, rhombi, and parallelograms.
Answer:
Here are the properties of the rhombus, rectangle, and square. Note that because these three quadrilaterals are all parallelograms, their properties include the parallelogram properties.
The rhombus has the following properties:
All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary).
All sides are congruent by definition.
The diagonals bisect the angles.
The diagonals are perpendicular bisectors of each other.
The rectangle has the following properties:
All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other).
All angles are right angles by definition.
The diagonals are congruent.
The square has the following properties:
All the properties of a rhombus apply (the ones that matter here are parallel sides, diagonals are perpendicular bisectors of each other, and diagonals bisect the angles).
All the properties of a rectangle apply (the only one that matters here is diagonals are congruent).

The equation of the parabola that represents the given graph is y = 3x².
The correct option is B.
What is a parabola?A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.
If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:
y = a x²
where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).
Plugging in the coordinates of the passing point (1, 3), we get:
3 = a (1)²
3 = a
Therefore, the value of "a" is 5.
Hence, the equation of the parabola is:
y = 3x²

Use what you already know to find a, b, and c.
Input each value. Then click done. HELP ME PLEASE FAST!
Answer:
Use the "find vertically opposite angle" method.
a = 80°
To find the other angles:
Since the angles equal up to 360 which makes a full circle shape...
360 - 80 - 80 = 200 (B and C)
200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)
b = 100°
c = 100°
A company makes 110 bags.
46 of the bags have buttons but no zips.
20 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer:
51/110
Step-by-step explanation:
No: of bags with buttons but no zips = 46
No: of bags that have both buttons and zipz = 110-(46+20+39) = 5
No: of bags with buttons = 46+ 5 = 51
Total no: of bags = 110
Probabilty = 51/110
