The answer is -1/3. So easy
Answer:
July savings= $35
August savings= $ 105
Step-by-step explanation:
Let's represent her JULY savings as "x"
Let's represent her August savings with (3 * x), since she saved three times her July savings.
Her Total savings for the both months are the sum of JULY savings and AUGUST savings which is equal to $140.00
Therefore:
x + 3x = $140
4x = $140
Divide through by 4
x = $140 / 4
x = $ 35.
It means the JULY savings (x) = $35.
Let's solve for AUGUST SAVINGS:
= 3 * x
When x = $35
August Savings = 3 * $35
= $ 105
Answer:
t = 0.722 seconds
Step-by-step explanation:
Given in the question that an equation
h = -16t² + 6t + 4
here h is the height
t is the time
To solve this question we need to substitute height with zero because at ground level height is zero
<h3>h = 0</h3>
0 = -16t² + 6t + 4
<em>a = -16</em>
<em>b = 6</em>
<em>c = 4</em>
Formula to use
t = -b±√(b²-4ac) / 2a
Plug values in the formula
t = -6 ± √36-4(-16)(4) / 2(-16)
t = 6±2√73 / 32
t = 6+2√73 / 32 or t = 6-2√73 / 32
t = 0.722 or t = -0.347
since time can't be in negative so we reject t = -0.347
