Answer:
1. 30 student
2. 120 student's didn't vote
3. 7 quarters
Step-by-step explanation:
1. first, see how many games can be played:
45÷3 = 15
then, multiply the number of games by two because 2 students can play per game
15 • 2 = 30
2. first, figure out what percent of students did not vote:
100 - 60 = 40%
then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:
300 • .40 = 120 student's didn't vote
3. first, find how much 9 dimes is:
1 dime = $0.10
9 dimes = 9 • $0.10 = $0.90
then, find how much money kerry had:
$2.65 - $0.90 = $1.75
finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:
1 quarter = $0.25
$1.75 ÷ $0.25 = 7 quarters
what type of communication coordinates actions within cells?
Answer:
Step-by-step explanation: Chemical signal is the type of communication which coordinates actions between neighboring cells . This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma membrane and changes are brought about within the cell in response to this message.

Jason bought 3 shirts that each cost the same. He had a coupon for $10 dollars off and he spent $65 altogether. Which equation can be used to find the cost of each shirt?
Answer: $18.33
Step-by-step explanation:
c = cost
c = (65-10) / 3
c = 18.3333333333
c = $18.33

Step-by-step explanation:
Write the equation of a line that passes through (4,5) with a slope of 3
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = 12 + c ⇒ c = 5 - 12 = - 7
y = 3x - 7 ← equation of line
VW = WX = YW = ZX = VX = view image attached thank youuu!
Answer:
assuming this is a rectangle:
VW=31
WX=19
YW=36.36
ZX=18.18
VX=36.36
Step-by-step explanation:
VW=VX
VW=31
WX=VX
WX=19
YW^2=19^2+31^2
YW^2=361+961
YW^2=1322
YW=36.36
ZX=1/2VX
ZX=18.18
VX=YW
VX=36.36
The measures of the rectangle are
a) The measure of VW = 31
b) The measure of WX = 19
c) The measure of YW = 36.36
d) The measure of ZX = 18.18
e) The measure of VZ = 18.18
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let the rectangle be represented as VWXY
Now , the diagonals of the rectangle are VX and WY
Substituting the values in the equation , we get
The measure of VY = 19
The measure of XY = 31
Now , for a rectangle the opposite sides are congruent
So , the measure of VY = measure of WX
And , the measure of XY = measure of VW
On simplifying the equation , we get
The measure of WX = 19
The measure of VW = 31
And , the diagonal of the rectangle = √ ( Length )² + ( Width )²
Substituting the values in the equation , we get
The diagonal of the rectangle YW = √ ( 31 )² + ( 19 )²
The diagonal of the rectangle YW = √ ( 961 + 361 )
The diagonal of the rectangle YW = 36.359 ≈ 36.36
And , the measure of VX = measure of YW = 36.36
Now , the measure of ZX = measure of VZ = measure of VX / 2
So , the measure of ZX and VZ = 36.36 / 2 = 18.18
Hence , the diagonal of the rectangles is 36.36

If rectangle LMNO were rotated 180° clockwise about the origin to create rectangle L'M'N'O', what would the measure of angle O' be?
9514 1404 393
Answer:
90°
Step-by-step explanation:
Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.
_____
Additional comment
No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.
