Answer:
Step-by-step explanation:
So we have the equation:
First, distribute the left side:
Add values on the left side:
Add 7 to both sides. The right side cancels:
Subtract 2x from both sides. The left side cancels:
Divide both sides by -6:
Therefore, x equals -3.
A prism with a volume of 270 m³ is dilated by a factor of 3. What is the volume of the dilated prism? Enter your answer in the box.
If we dilate each dimension by 3, then the volume of the figure will be dilated by .
=3*3*3 =27
So, the volume of the dilated prism is *volume of original prism
Volume of dilated prism=27*270
Volume of dilated prism=7290
Answer:
Percentage change in price = 13.80%
Step-by-step explanation:
Given that:
Original price = £57.99
Decreased price = £49.99
Difference = Original price - Decreased price
Difference = 57.99 - 49.99
Difference = £8.00
Percent change =
Percent change =
Percent change in price = 13.80%
Hence,
Percentage change = 13.80%
Answer:
if the starting temp was 34 and then it dropped 27 degrees that means the temperature went down to 7 degrees. it now says the temp tripled so you would multiply that 7 by three and be left with 21 degrees at 12pm
i believe the answer is 21 degrees
Answer:
x^2+y^2 = 3^2
Step-by-step explanation:
We need to eliminate the parameter t
Given:
x = 3 cos t
y = 3 sin t
Squaring the above both equations
(x)^2=(3 cos t)^2
(y)^2 =(3 sin t)^2
x^2 = 3^2 cos^2t
y^2=3^2 sin^2t
Now adding both equations
x^2+y^2=3^2 cos^2t+3^2 sin^2t
Taking 3^2 common
x^2+y^2=3^2 (cos^2t+sin^2t)
We know that cos^2t+sin^2t = 1
so, putting the value
x^2+y^2=3^2(1)
x^2+y^2 = 3^2
Hence the parameter t is eliminated.
