Step-by-step explanation:
(1)
given
4x² = 81 ( divide both sides by 4 )
x² = ( take the square root of both sides )
x = ± = ±
---------------------------------------------------------------------
(2)
subtract 7 from both sides
(4x - 3)² = 32 ( take the square root of both sides )
4x - 3 = ± = ± 4
Add 3 to both sides
4x = 3 ± 4 ( divide both sides by 4 )
x = ±
Answer:
If there is 5 peices of a report and Gavin has written 2 out of 5 of those pieces, then there is only 3 pieces left. Meaning Oliver and Michael will either split 1.5 a nd 1.5 of the 3 pieces or one will take 2 and the other will take one.
Answer:
21.9 feet
Step-by-step explanation:
The question is incomplete. Here is the complete question.
<em>Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
</em>
<em>Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
</em>
<em>
</em>
Given parameters
Altimeter of vivian at its lowest point = -9.6 feet
Altimeter of vivian at the top of the wheel = 12.3feet
Note that the sea level is at 0 feet.
change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:
= (12.3-0)+(0-(-9.6))
= 12.3+(0+9.6)
= 12.3+9.6
= 21.9 feet
From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.
The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.
Answer:
The new width is 3 in.
Step-by-step explanation:
We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.
<u>12 </u>= <u>x</u>
16 4
Then solve for x:
x = 4 (12/16)
x = 3
To check:
12/16 = 3/4
3/4 = 3/4
