The parent volunteers made 120 snow cones in 5 hours. The student council made 100 snow cones in 4 hours. Who made more snow con
marysya [2.9K]
The parent volunteers:
120 snow cones ... 5 hours
x snow cones = ? ... 1 hour

120 * 1 = 5 * x
120 = 5 * x   /5
x = 120 / 5 = 24 snow cones

The student council:
100 snow cones ... 4 hours
y snow cones = ? ... 1 hour

100 * 1 = 4 * y
100 = 4 * y   /4
y = 100 / 4 = 25 snow cones

Result: The student council made more snow cones per hour (25 > 24).

Which equation can be solved by using this expression?
Marat540 [252]

<u>Answer:</u>

The correct answer option is B. 2 = 3x + 10x^2

<u>Step-by-step explanation:</u>

We are to determine whether which of the given equations in the answer options can be solved using the following expression:

x=\frac{-3 \pm\sqrt{(3)^2+4(10)(2)} }{2(10)}

Here, a = 10, b = 3 and c=-2.

These requirements are fulfilled by the equation 4 which is:

12=3x+10x^2

Rearranging it to get:

10x^2+3x-2=0

Substituting these values of a,b,c in the quadratic formula:

x= \frac{-b \pm \sqrt{b^2-4ac} }{2a}

x= \frac{-3 \pm\sqrt{(3)^2-4(10)(-2)} }{y}

Least to greatest 0.94,9.40,0.094,94.0,94.0
sertanlavr [38]
Here's an example number:
123.456
The place values are, from greatest to least:
The 1 is in the <em /><em>hundreds</em> place
The 2 is in the <em /><em>tens</em> place
The 3 is in the <em>ones</em> place
The 4 is in the <em>tenths</em> place
The 5 is in the <em>hundredths </em>place

If you have some number like 9.40 with no decimal point, shifting it will change the value. Moving the decimal one place to the right multiplies the value by ten. (94)
Moving it one place to the rigt divides it by ten. (0.94)

Here's our list from least to greatest:
94.0
9.40
0.94
0.094
