A percent can be viewed as a fraction over 100, so in this case, we form the fraction 80/100.
However, this is not in simplest form. The largest number that goes into both of these (greatest common factor) is 20, so we should divide the numerator and denominator by 20.
When we do this, we can see that the simplest fraction to represent 80% is 4/5.
Answer:
The second option, 6
Step-by-step explanation:
<em>opening the parentheses</em><em>,</em><em> </em><em>the</em><em> </em><em>equa</em><em>tion</em><em> </em><em>becomes</em><em>,</em>
4y - 24 = 0
4y = 24
y = 6
Answer: x < 30
Step-by-step explanation:
Let the cost of a jean be x
cost of a shirt = $25
cost of 3 jeans = 3x
since he wants to spend less than $115 , this means that
3x + 25 < 115
3x < 115 - 25
3x < 90
x < 30
1.B - - original function is y = sqrt(x). If we make sqrt(x+4), we will move the original function to the left 4. If we make sqrt(x+4)+3, additionally the original function will be moved up 3.
2.D - original function is y = sqrt(x). If we make sqrt(x-7), we will move the original function to the right 7. If we make 5*sqrt(x-7), additionally the original function will be expanded throw the y-axis.
3.E - original function is y = x^5. If we make -x^5 (multiply x^2 by -1), we will reflect the original function over the x-axis. If we make -x^5 - 4 , we additionally will move the original function down 4.
4.C - original function is y = x^2. If we make (x-3)^2, we will move the original function to the right 3. If we make x^2 - 5 , we will move the original function down 5.
5.A - original function is y = x^2. If we multiply x^2 by 1/3, function will be compressed about the y-axis.
