Answer:
its value is 120° ................
Answer:
Step-by-step explanation
Step 1: multiply the coefficient a and the constant c. Given that the general expression of a parabolic equation is ax^2+bx+c
3*5=15
Step 2: examine the coefficient b and try to find 2 numbers which you can multiply to get 15, add or subtract and get - 8
In this Case: - 3*-5=15 and - 3+(-5)= - 8
Step3:
You separate the equation in terms of the two factors you have found
3x^2-3x-5x+5=0
Step 4:Factorise
3x(x-1)-5(x-1)=0
(3x-5)(x-1)=0

Monday
1.) <em>1250 gallons of water for 1 ounce of Granular chlorine.</em>
<em></em>
2.) <em>w = 1250c</em>
Tuesday
9.5% of 50
0.095 × 50 = 4.75
<em>The fee costs $4.75</em>
Since the fee will be deducted from the selling price..
50 - 4.75 = 45.25
<em>Once he pays for the fee, he'll make $45.25.</em>

Wednesday
To get 1 cup of sugar, you multiply 4 to 1/4 meaning to find the proportional amount of flour used, you have to multiply 2/3 by 4
2/3 × 4 = 8/3
<em>She should use 2 ²/₃ cups of flour</em>
Since in the new recipe, we're multiplying everything by 4..
16 × 4 = 64
With this new recipe, she can make 64 cookies.
Thursday
4800 ÷ 6400 = 0.75
0.75 × 100 = 75
4800 is 75% of 6400
100 - 75 = 25
<em>So, the cost of health insurance for the family increased by 25%</em>
