Answer: 18cm
Step-by-step explanation:
Let original drawing's base be b.
We are using scale factor of 0.4, so
0.4 of b = 7.2cm
0.4 × b = 7.2cm
b = (7.2/0.4)cm
b = 18cm
Answer:
x = 8
Step-by-step explanation:
Angle J = Angle P, and Angle L = Angle L so the triangles have the same angle measures all the way around. Triangle JKL is the same as Triangle LMP, but smaller. it has been reduced by a ratio of 4:6. You then divide 4 by 6 to get the ratio in decimal form, and then multiply that by 12 to get the equivalent length for JK to PM
Answer:
No. They are not equivalent.
Step-by-step explanation:
=>
Therefore, 3/5 and 1/2 are not equivalent.
Hoped this helped.
Answer:
Step-by-step explanation:
we know that
In this problem
The value of x represent the radius of the circle
so
Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O
see the attached figure to better understand the problem
square root both sides
Answer:
The volume of a rectangular prism is
V = l · w · h
V= 252 cm3
h= 3 cm
l=5+W
W=x then l=5+x
V=(5+x)*x*3=252
3x^2+15x=252 cm3
the equation that models the volume of the tray in terms of its width, x, in centimeters.
3x^2 +15x=252 cm3
for width=7.5 cm
3x^2 +15x=3*(7.5) ^2+15*7.5= 281.25 cm3
281.25>252
it is not possible that the width is 7.5 cms
