The ratio is b:s:g=20:22:18  and if we only care about berries and grapes the ratio is:

b:g=42:18 now we can set up a relationship to solve...

3g(42b/18g)=7b

So using 3 cups of grapes requires 7 cups of berries in total.

A park has a length to width ratio of 7:4 and the perimeter of the park is 880 meters. What are the length and width of the park
Schach [20]

Step-by-step explanation:

Ratio of length to width = 7 : 4

length = 7x

width = 4x

7x + 4x = 11x

length = 880

880 + 4x = 11x

880 = 11x - 4x

880 = 7x

\frac{880}{7}  = x

125.71 = x

width = 4x

= 4(125.71)

= 502.85

Uptown Country Club only admits members with annual incomes in the top 2.5% of the United States. If the annual individual incom
Verdich [7]

Answer:

$74,600

Step-by-step explanation:

-Given the probability is 2.5%, mean=$55,000 and standard deviation= $10,000

-We find the z value of 2.5%

p=P(z>\frac{X-\mu}{\sigma})\\\\1.96=P(z

Hence, the minimum amount of income to be in the top 2.5% is $74,600

Select all the correct graphs.<br> Choose the graphs that indicate equations with no solution.
Natali [406]

Answer:

The first and last graph.

General Formulas and Concepts:

<u>Algebra I</u>

  • Solving systems of equations graphically

Step-by-step explanation:

In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.

Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.

1.) What is slope and how is it determined from an graph?
Daniel [21]

1) Slope tell about the steepness of the line.

To find slope we look at the rise and run between 2 points.


attached the graph of line with slope


slope = \frac{change in y values ( rise)}{change in x value (run)}

= \frac{2}{1}

So slope = 2

2) we have x and y intercepts


x intercept is the point where the line crosses x axis


x intercept at x= 3


y intercept is the point where the line crosses y axis


y intercept at y= 6

3) Linear equation is y= 3x+2

function is f(x) = 3x+2

We can graph it using slope and y intercept


In f(x)= 3x + 2 , slope =3 and y intercept = 2


slope = 3, rise = 3 and run =1


The graph of f(x)= 3x+2 is attached below.
