Answer:
x = 64 m
Step-by-step explanation:
The scale is proportional to the actual:
(6 m)/(3/4 cm) = x/(8 cm)
Multiplying by 8 cm, we get ...
x = (8 cm)·(6 m)/(3/4 cm)
x = 64 m . . . . the width of the actual wall
Answer:
-2³/₈
Step-by-step explanation:
(-13/8)+(-3/4)
the l.c.m is 8
(-13+(-6))/8
(-13-6)/8
-19/8 = -2³/₈
Hello from MrBillDoesMath!
Answer:
11 sqrt(2)
Discussion:
See attachment in which it is shown that c = sqrt(242) = sqrt(121*2) = 11 sqrt(2) as sqrt(121) = 11.
Thank you,
MrB
Answer: w lesser than or equal to 4
Step-by-step explanation:
Dwight and Walt are building model cars.
Let d = the number of models built by Dwight.
Let w = the number of models built by Walt.
Dwight builds 7 fewer models than 4 times the number Walt builds. This can be expressed as
d = 4w - 7 - - - - - - - - - 1
Dwight builds at most 9 models. This is expressed as
d lesser than or equal to 9
From equation 1
d = 4w - 7
4w = d + 7
w = (d+7)/4
Assuming Dwight built 9 models
w = (9+7)/4 = 4
Therefore,
Walt builds at most 4 models. It is expressed as
w lesser than or equal to 4
