A) No solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is negative. 

B) One solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is equal to 0.

Gerrie collects honey from a few
neonofarm [45]

The number of the cups of honey has she collected will be 52 and 2/3 cups.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Gerrie collects honey from a few beehives.

She scoops out the honey with a small jar that holds 1/3 of a cup.

Over the last two weeks, Gerrie has filled this jar 158 times.

1 small jar = 1/3 cup

But we have done this for 158 times. Then we have

158 small jar = 158 x 1/3 cups

158 small jar = 52 and 2/3 cups

More about the ratio and the proportion link is given below.

Which formula represents calculating the slope?
k0ka [10]

C. All of the above. Both formulas represents in calculating the slope.

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

The slope(m) can be identified by the formula rise over run.

i.e. m=\frac{rise}{run}.

Rise is how much the line gone vertically ( y-axis) from the origin.

Run is how much the line gone horizontally (x-axis) from its origin.

∴ Rise = y_{2} - y_{1}

And Run = x_{2} - x_{1}.

⇒ m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}.

Thus both equations can be used to find the slope of the line intercept.

If the points are given you can chose them yourself from the graph. Just consider any two points on the line.

tammy typed 40 pages of a report on Monday and 3/8 of the report on Tuesday. She completed the remaining 1/3 of the report on We
sergeinik [125]

Answer:

Step-by-step explanation:

R = report length

R = 40 + (3/8)R + (1/3)R

3/8 = 3*3/8*3 = 9/24

1/3 = 8*1 / 3*8 = 8/34

R = 40 + (9/24)R + (8/24)R

R = 40 + (17/24)R                         Subtract 17/24 from the left

R-17/24 R = 40

7/24 R = 40                                  Multiply both sides by 24

7R = 40 * 24

7R = 960                                       Divide by 7

R  = 960/7

R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138
