Well simply put we know that Celia's collection of cards is bigger because it tells us that it is 4/3 times bigger than franks. If you convert 4/3 to a percent you would see that is is over a hundred percent, so you know hers is bigger than his.
Answer:
15 B
16 B
17 A
Step-by-step explanation:
A triangle is a figure with three sides.
Which can be re-written in the if-then form as If the figure is a triangle then it has three sides.
The elevator has a MAX capacity of 8 people. This means that only 8 or less people can be on the elevator at a time. If c = # of people then c must be less than or equal to 8 as the elevator has a max capacity of 8 people. Hence the mathematical statement would be c ≤ 8
When the inequality sign is facing the "y" the solutions to the set can be found above the line. This could also be checked by graphing.
1 L = 1000 mL
1 kg = 1000 g
You can use this to convert the equations.
200 mL of paint x 5 = 1000 mL (1 liter)
40 g x 5 = 200 grams of paint powder
200 g x 20 = 4000g of paint powder for 20 liters of paint
4000g/600g = 6 2/3
You’ll need 7 packets of paint powder.
Answer:
Step-by-step explanation:
Use equation
20000-16000=4000
20000:100=4000 :x
x20000=400000
x=400000/20000
x=20 %
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(3,8)(-7,11)
d = sqrt (-7 - 3)^2 + (11 - 8)^2
d = sqrt (-10^2) + (3^2)
d = sqrt (100 + 9)
d = sqrt 109
d = 10.44
===============
mid-point formula : ((x1 + x2) / 2 , (y1 + y2) / 2)
(-9,5)(21,-7)
midpoint = ((-9 + 21)/2 , (5 + (-7)/2)
= ((12/2) , (-2,2))
= (6, -1) <==
=======================
(-8,7)(-9,11)
midpoint = ((-8 + (-9) / 2, (7 + 11)/2 )
= (-17/2, 18/2)
= (-8.5, 9) <==
======================
(8,y)(-11,6).....midpoint = (-1.5/5)
midpoint = ((8 + (-11)/2, (y + 6)/2)
= (-3/2), (4 + 6)/2
= (-1.5,5)
y = 4 <==
======================
slope = (y2 - y1) / (x2 - x1)
(3,-6)(6,12)
slope = (12 - (-6) / (6 - 3) = (12 + 6) / 3 = 18/3 = 6 <==
======================
(x,10)(-4,8)...slope = 2/3
y = mx + b
slope(m) = 2/3
(-4,8)...x = -4 and y = 8
sub and find b
8 = 2/3(-4) + b
8 = -8/3 + b
8 + 8/3 = b
24/3 + 8/3 = b
32/3 = b
equation is : y = 2/3x + 32/3 or 3y = 2x + 32
when y = 10
3(10) = 2x + 32
30 - 32 = 2x
-2 = 2x
-2/2 = x
-1 = x <===
=================
(9,0)(3,y)...slope = 1/2
y = mx + b
slope(m) = 1/2
(9,0)...x = 9 and y = 0
sub and find b
0 = 1/2(9) + b
0 = 9/2 + b
-9/2 = b
equation is : y = 1/2x - 9/2 or 2y = x - 9
sub in 3 for x and solve for y
2y = 3 - 9
2y = -6
y = -6/2
y = -3 <==
=================
(8,7)(11,7)...notice how the y values are the same. This means it is a horizontal line. A horizontal line has a slope of 0.
====================
sorry...not too good with the picture graphs
