Edward counted out 20 cards for a card game. Then he split those cards evenly among the 4 players.
The letter c stands for the number of cards for each player. Which equation can you use to find c?
option
20-4=C
20/4=C
Answer:
20/4=c
Step-by-step explanation:
You can tell that that is the right answer, because 20-4=c means that each person would get 16 cards, and if you multiply that by 4(the amount of people that are playing) It's way more than 20 cards, so you know that 20/4=c is the right answer. Hope that helped;)

Answer:
RECTANGLEA rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals.
Rosalinda has a circular serving platter in the middle of her circular table.
The radius of the platter is 15 inches less than the radius of the table
The diameter of the table is 4 feet. What is the difference between the
area of the table and the area of the platter? Use 3.14 for 17, and write your
answer in decimal form. 7.G.4
diameter=4ft=12(4)=48in
Radius of table=48/2=24inRadius of platter=24-15=9inSo
Area of table:-
π(24)^2576πin²Area of platter:-
9²π81π in²Difference:-
576π-81π495π1554.3in²Answer:
1554.3 in²
Step-by-step explanation:
Given information:
The radius of the platter is 15 inches less than the radius of the tableThe diameter of the table is 4 feetπ = 3.141 foot = 12 inches
⇒ 4 ft = 4 × 12 = 48 in
Radius = ¹/₂ diameter
⇒ Radius of table = ¹/₂ × 48 in = 24 in
⇒ Radius of platter = 24 in - 15 in = 9 in
Area of a circle = πr²
⇒ Area of table = 3.14 × 24² = 1808.64 in²
⇒ Area of platter = 3.14 × 9² = 254.34 in²
Difference = area of table - area of platter
= 1808.64 - 254.34
= 1554.3 in²
(a) The area of a rectangular parking lot is 3657 m².
If the width of the parking lot is 53 m, what is its length?
Answer:
69 m
Step-by-step explanation:
[tex]\textcolor{steelblue}{\text{Area of rectangle= length ×width}}[/tex]
Given that the area is 3657 m² and the width is 53 m,
3657= length ×53
Divide both sides by 53:
length= 3657 ÷53
length= 69 m
Define a rational number and show that no rational number x belongs to Q satisfies x² = 2
Answer:
A rational number is a number that can be expressed as a fraction of two integers.
if x²=2 then x=√2, but √2 is an irrational number (not rational), so there is no rational number x that satisfies x² = 2.

a. Sarah Smartshopper receives ten cents off per gallon on gas for every $100 she
spends at the grocery store during a given month. During the month of October,
he spent $45.23, $102.34, $13.67, $34.56, $48.72, and $52.12. What will Sarah's
gas discount be for October?
Using proportions, it is found that her discount is of $0.29664.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the total amount she spent on gas is given by:
T = $45.23 + $102.34 + $13.67 + $34.56 + $48.72 + $52.12 = $296.64.
Considering that she receives ten cents off per gallon on gas for every $100 she spends, we apply the proportion to find that her discount is given by:
[tex]D = 0.1 \times \frac{296.64}{100} = 0.29664[/tex]
Her discount is of $0.29664.

Can slope intercept form have y as the slope?
For example:
x = 7y
Answer:
yes
Step-by-step explanation:
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept.
Write the equation of the parabola in vertex form.
vertex (2,4), point (3,2)
Answer:
y=-3(x-2)^2+4
Step-by-step explanation:
The general equation for the data given is y = a(x-2)^2 + 4 based on the vertex information.
To find a, we use (3,1) to substitute. 1 = a(3-2)^2 + 4 or a = -3
So the full equation is y = -3(x-2)^2 + 4

Critical Thinking: I am a 7-digit number. All my digits are non-zero and distinct, My ones digit is four times the tens digit. • The sum of the ones and tens digits is equal to the sum of the lakhs and ten lakhs digits. • The sum of the ten thousands and thousands digits is equal to the double of the hundreds digit. • The ten lakhs digit is greater than the lakhs digit , and the ten thousands digit is greater than the thousands digit. Find which number I am.
Answer:
3286714
Step-by-step explanation:
Let the digits of the number be :
ABCDEFGOur given conditions :
G = 4F [ones digit is four times the tens digit]G + F = B + A [sum of the ones and tens digits is equal to the sum of the lakhs and ten lakhs digits]C + D = 2E [sum of the ten thousands and thousands digits is equal to the double of the hundreds digit]A > B and C > D [ten lakhs digit is greater than the lakhs digit , and the ten thousands digit is greater than the thousands digit]Solving :
Condition 1 : G is either 1 or 2 and F is either 4 or 8For now, let G be 1 and F be 4 Now G + F = A + BThen A + B = 5 [but not 1 + 4] ⇒ A can be 3 and B can be 2Now C + D = 2E and our remaining numbers are 5,6,7,8,9C and D can be 8 and 6, then their mean would be 7, which is ESolution :
So, the number is :

Let's solve ~
Circumference of a circle :
[tex]\qquad \tt \dashrightarrow \:2 \pi r[/tex]
And we have been given that Circumference = 24 cm
So, let's equate them and find radius (r) :
[tex]\qquad \tt \dashrightarrow \:2 \pi r = 24[/tex]
[tex]\qquad \tt \dashrightarrow \:r = \dfrac{ 24}{2 \pi}[/tex]

So, we got the radius here. now let's equate it with expression in terms of x to find value of x
[tex]\qquad \tt \dashrightarrow \: \sqrt{x + 2} = 3.82[/tex]
[tex]\qquad \tt \dashrightarrow \:{x + 2} = (3.82) {}^{2} [/tex]

What is law of sine?Law of sine says that ratio of sine of an angle and its opposite side is always same for every 3 angles of the triangle and their opposite sides.
In ΔABC,
sinA/a = sinB/b = sinC/c
in the given triangle ΔIJK
∠J=34°
∠I=72°
i=206
So, using law of sine,
sinI/i = sinJ/j
⇒sin72°/206=sin34°/j
⇒j=(sin34°/sin72°)*206
⇒j=121.1
Therefore, the value of j will be 121.1

The equation of the line that passes through (1,2) and is parallel to the line y=-5x+4, is y=-5x+7.
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
[tex]y=mx+c[/tex]
Here, (m) is the slope of the line and (c) is the y intercept.
This line is parallel to the line which has to be find out is,
[tex]y=-5x+4[/tex]
As the parallel lines have same slope. Thus, the line which is required to find has a slope of -5.
Compare with standard equation of line, we get the slope of the line,
[tex]m=-5[/tex]
Thus, the equation of line become,
[tex]y=-5x+c[/tex]
The line passes through (1,2). Put these values in the above equation as,
[tex]2=-5(1)+c\\2=-5+c\\c=2+5\\c=7[/tex]
Thus, the equation become,
