Answer:
t is between 0 seconds and 4.878
Step-by-step explanation:
Given:
Inequality:
Required
Determine the value(s) of t
To answer this question, we simply solve the inequality
Subtract 10 from both sides
Multiply through by -1
Solve the value of t using quadratic formula
Where
<em>a = 4.9; b = -22 and c = -9.25</em>
So:
Split the expression
or
or
or
Since t cannot be negative; Then
<em>Hence; t is between 0 seconds and 4.878</em>
Answer:
B) - 53 + 4k = 7
Step-by-step explanation:
Substitute k=15 into each equation
A) 3k - 11 = -34
3(15) -11 = -34
45 -11=-34
34 = -34
not true
B) - 53 + 4k = 7
-53 +4(15) =7
-53 +60=7
7 =7
true
C) k/3 + 17 = 12
15/3 +17 =12
5+17 =12
22 =12
False
D) k/5 + 2.5 = 0.5
15/5+2.5 =.5
3 +2.5 =.5
5.5 =.5
False

A teaspoon of honey= 1 teaspoon of honey = 504 cal
a teaspoon of sugar = 1 teaspoon of sugar = 560+16 = 576 cal
y = 16x + 560 calories
y=64x+440 calories
Add them and that's how you check. :)
(If that doesn't make sense, Sugar has 16 Cal. and Honey has 64 Cal.)
Answer:
The correct answer is option C. 3
Step-by-step explanation:
It is given an expression in variable x
(x² + 3x²)/(x + 1) ÷ (x² - 9)/(3x + 3) * (x - 3)/x
<u>To find the simplified answer</u>
x² + 3x² = x(x + 3)
x² - 9 = (x + 3)(x - 3)
The given expression can be written as,
(x² + 3x²)/(x + 1) ÷ (x² - 9)/(3x + 3) * (x - 3)/x
= x(x + 3)/(x + 1) * 3(x + 1)/(x + 1)(x - 1) * (x -3)/x
=[ x(x +3) * 3(x +1) * (x -3)]/[(x + 1) * (x + 3)(x - 3) *x]
= 3
The correct answer is option C. 3
