Answer:
Marina's design uses more cardboard.
in Kristen's design, it uses:
3*4/2*2+10*5+3*10+4*10=132 sq inches.
in Marina's design, it uses:
6*3*2+3*7*2+7*6*2=162 sq inches.
132<162
Therefore Marina's design uses more cardboard.
The difference between 2 designs are:
162-132
=30 sq inches
Answer:
4.2 pints
Step-by-step explanation:
3.5 × 1.2 = 4.2
Answer: 4.2 pints
#1. 5(t+3)=-10
5t+15=-10
5t=-25
t=-5
#2. -(c-10)=0
-c+10=0
c=10
#3. -10(s+3)=-15
-10s-30=-15
-10s=15
s=-3/2
#4. 5(f-5)=-60
5f-25=-60
5f=-35
f=-7
#5. -5(2t+2)=-70
-10t-10=-70
-10t=-60
t=6
#6. 4(3w+2)/3=-6
12w+8=-18
12w=-26
w=-13/6
#7.Substitute the °C with -8
Equation:
5/9(F-32)=-8
divide both sides by 5/9
F-32= -14.4
add 32 to both sides
F=17.6
Answer: -8°C in °F is approximately 18°F.
BTW, to get the degree sign, it's option+shift+8.
Answer:
23
Step-by-step explanation:
Ā means the average
So it means the average of 64 gave their speech which should be 64/2 = 32
So 32 gave their speeches yesterday,
7 gave today
Total number that has given is
32 + 7 = 39
Therefore the number remaining are
62 - 39 = 23
898.55 = 4.55 × 26 + t
t = tips
4.55 × 26 = 118.3
898.55 = 118.3 + t
898.55 - 118.3 = 780.25
780.25 = t
Your answer is D
