Amanda is going to make up some concrete by
lianna [129]

Answer:

Yes, Amanda has enough materials to make the concrete mix.

Step-by-step explanation:

Total units = 1+3+5

                 = 9

9 units = 630kg

1 unit = 630kg ÷ 9

        = 70kg (Less than 80kg of cement, more than enough)

3 units = 3 × 70kg

           = 210kg (Less than 215kg of sand, more than enough sand)

5 units = 5 × 70kg

           = 350kg (Less than 370kg of gravel, more than enough gravel)

Wht is 84 is 74% of what number
Elina [12.6K]
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.

Which is a zero of the quadratic function f(x) = 9x2 – 54x – 19?
liraira [26]

Answer: Third Choice. x= 6 1/3

Step-by-step explanation:

Given

f(x) = 9x² - 54x - 19

Completing the square

3x          -19

3x          1

Substitute back to the function

f(x) = (3x-19) (3x+1)

Simplify

x= 6 1/3 or -1/3

Hope this helps!! :)
