order does not matter:so its a combination ways to choose 3 out of 5 letter= 5C3=5!/(5-3)!3!=10 ways ways to choose 2 letter p's: 2C2=1 for h=1 for a=1 for y=1 ans.= 1/10
let x-first no. x+(x+1)+(x+2)+(x+3)+(x+4)=225 5x+10=225 x=43 largest no.= (x+4)=43+4= 47 Ans: 47
TODAY
4/5X$15=12$ she spent less than $15.
3/8 X 6 miles= 9/4 or 2.25 miles he ran less than 6 miles.
more than 3 cups. 2 1/3 to improper fraction is = 7/3 7/3 X 3 times= 7 cups..
let n-1st no. m-2nd no. n+m=(nXm)+1-----eqtn. 1 n-m=(nXm)-5-----eqtn. 2 solve by elimination n+m=(nXm)+1-----eqtn. 1 - n-m=(nXm)-5-----eqtn. 2 ________________________________ 2m=6 m=3 subst. to eqtn 1 or 2 n+m=(nXm)+1-----eqtn. 1 n+3=3n+1 -2n=-2 n=1
5^x=(5^2(2x-1))(5^3(4-2x)) 5^x=(5^(4x-2))(5^(12-6x)) 5^x=5^(4x-2+12-6x) 5^x=5^(-2x+10) x=-2x+10 3x=10 x=10/3 or 3.3333 or 3.33 with bar on top
difference of points= 7.1m-2.1m= 5 m horizontal distance= 6 meters. it forms a right triangle. Use phythagorean theorem: c^2=a^2+b^2 in this case: a=5m and b=6m or either way. c^2=5^2+6^2 c^2=25+36 c^2=61 by square root: (both sides) c=sqrt61 c=7.81 m
Let: M=Mary's age now C=Cora's present age M-7=6(C-7) M+1=2(C+1) M=2C+1 (2C+1)-7=6C-42 2C-6=6C-42 -4C=-36 C=9 therefore Cora's age now is 9 yrs. old M=2C+1 M=2(9)+C M=19 therefore Mary's age now is 19 yrs. old.
let: J=jades age now T=Timmy's age now interpretation: J=T+5-----eqtn.1 T-6=J/2----eqtn.2 substitute eqtn 1 to 2 T-6=(T+5)/2 2(T-6)=T+5 2T-12=T+5 T=17 Timmy's age now is 17 yrs. old Subs. to eqtn. 2 J=T+5 J=17+5 J=22 Jade's age now is 22 yrs. old. check:
let: n=the number m=the other number n=8+m-----eqtn 1 nXm=20-----eqtn.2 substitute eqtn1 to eqtn2 (8+m)(m)=20 8m+m^2=20 arrange m^2+8m-20=0 it forms into quadratic eqtn. factor by grouping (m-2)(m+10)=0 by zero property of equality we have: m=2 and m=-10
R=rate d=distance t=time c=current d=(R+C)(t) 625=(R+50)(t) 425+(R-50)(t) 625/(R+50)=t 425/(R-50)=t equate these two. 625/(R+50)=425/(R-50) cross multiply 625R-31250=425R+21250 625R-425R=21250+31250 200R=52500 R=262.5 R=263 mi/hr. check: 625=(263+50)t
just figure out the connection between the 2 pair of words like: Salesperson: persuasive salesperson do good in salestalk to persuade customers to purchase the product.. in this case, it is a characteristic of a salesperson to be persuasive. Secretary:
rate: 1deg/30min = 0.0333deg/min temp=rate X time 20deg= (0.333 deg/min) X t (20deg/0.333deg/min)=t t= 600 min t=(600 min)X 1hr/60min t=10 hrs reference time=6:00 pm t= 4:00 pm. each 1 deg increment will reach up to 20deg at 4:00 pm
