Ratio of Perimeters is 2/5 Ratio of areas is4/25
24/36 is the scale factor. Simplify to 2/3 Ratio of areas is 4/9
1600 contains 160 $10 dollar bills. Take $3 out of each. 160 x 3 = 480 So he took a total of $480 to divide among 4 employees, so each got $160
All you know the the length of the sides of the triangle so you need to use Heron’s Formula which is a method for calculating the area of a triangle when you know the lengths of all three sides but not the height. A = √p(p-a)(p-b)(p-c) where p is half the perimeter...
I assume you mean slope is -? and coordinate (-3,8) the equation is y =-2x/3 + b substitute 8 =6/3 +b 24 = 6 +3b 18=3b b=6 The y-intercept is 6 ...
The units used are feet. Pythagoras says x2 + x2 +6x+9 = 4x2 - 12x+9 so let's simplify that. 0=2x2 -18x factor and use the zero product property 0=2x(x-9) x=0 or x=9 eliminate x=0 because...
-20 is the slope of the function. It seems that for every hour of playing video games you lose 20 hours of "homework focus" whatever that is!
63 = 216 43 = 64 substitute 216x3 - 64 = (6x)3-(4)3 a3- b3 = (a-b)(a2+ ab + b2) (6x-4)(36X2 +24X +16) ...
Boyle's Law says in a closed system the pressure exerted by a given mass of gas is inversely proportional to the volume if the temperature stays the same. PV=k or PV=P1V1 The variables are pressure and volume.
Either (2x+1) is negative Or (2x+1) is positive 2x+1<0 2x+1>0 2x<-1...
You can distribute or use FOIL (First, Outer, Inner Last) x + 2 x + 2 2x + 4 x2+2x x2 +4x +4 answer (x...
Slope is change in y over change in x. Look at the two points; P1 has a y-value of -4 P2 has a y-value of +4 The change in y is 8 units! Think: what's the difference between -4 and +4? Or, thing what's the distance on the number...
Intercept is like intersection; the point where streets cross, or where lines cross. The axes are lines also. The x- intercept is the value of x in the point (x,0) The y- intercept is the value of y in that point (0,y) Think about what...
Isosceles right triangle has area 5400 sq ft Sides are in the ratio 1:1:√2 Let x be the length of a side. The altitude is x√3 5400 = ½ (x)(x√3) 2700/(√3
Circular Pizza had 14 in diameter or 7 in radius Area = π (7)2 = 153.93 sq in 30.8 sq/in is how much each of the 5 people get
Use a Venn diagram One circle is labeled cars with automatic transmissions, the other circle is labeled cars with bucket seats. the region common to both circles is called the intersection. Let x be the number of cars in the intersection 34-x=12 x=22 So...
Let l be the longer leg, then the shortest leg will be l-1 Use the Pythagorean Theorem: the hypotenuse of a right triangle equals the sum of the sides squared l2 + (l-1)2 = (l +1)2 l2 + l2 - 2l +1...
Let w be the width Then the length is 3w -13 A +(3w-13)W 56=3w2 -13w 0=3w2 -13w -56 0= (3w +8 )(w-7) w-7 =0 0r 3w +8=0 w=7 ...
Let c be the cost of a cheeseburger, and l be the cost of a cup of lemonade in dollars. 3c+2l = 14 Multiply each term by 2 6c+4l = 28 2c +4l = 12 Multiply each term by (-3) ...
