Answer:10%= 310
5%= 155
15%=465
Step-by-step explanation: Solution for what is 15% of 3100
3100/x=100/15
(3100/x)*x=(100/15)*x - we multiply both sides of the equation by x
3100=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x
3100/6.66666666667=x
465=x
x=465
Answer:
C
Step-by-step explanation:
The quotient of 17 divided by 10 is the fraction 17/10 or simplified 1 7/10, 1.7 or 1 R 7. It is NOT 10 / 17. C is the correct answer since it does not represent the quotient described.
The vertex form is y=(x-4)^2-1
From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"
y^2 + b^2 = a^2
y^2 + c^2 = x^2
y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2
a^2 - b^2 + c^2 = x^2
Now put in the values given for a,b,c to solve for x
(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x
Answer:
1) x > -12
Step-by-step explanation:
first, subtract 7 from each side of the inequality to get:
-2/3x < 8
multiply each side by the reciprocal of -2/3 which is -3/2 to get:
x > -24/2
notice the symbol has been reversed because that is the rule whenever you multiply or divide an equality be a negative value
simplified, answer is x > -12
