Find the value of x.<br> A. About 57.6<br> B. About 42.6<br> C. About 12.6<br> D. About 27.6
nordsb [41]

Answer:

about 27.6

Step-by-step explanation:

The sum of interior angles for this rectangle is 1080

119+140+124+6x+132+132+102 = 1080 add like terms

749 + 12x = 1080 subtract 749 from both sides

12x = 331 divide both sides by 12

x = 27.6 approximately

Ben strikes out 90 times in 340 at bat. What percent of the time does Ben strike out
nikklg [1K]

Answer:

percentage=26.47\%

Step-by-step explanation:

Ben\ strikes\ in\ 340\ efforts=90\\\\So\ fraction\ he\ can\ strike\ 1\ effort=\frac{number\ of\ times\ he\ strikes}{total\ efforts}\\\\So\ fraction\ he\ can\ strike\ in\ 1\ effort=\frac{90}{340}\\\\So\ fraction\ he\ can\ strike\ in\ 1\ effort=\frac{9}{34}\\\\He\ can\ strike\ in\ 100\ efforts=\frac{9}{34}\times 100\\\\percentage=26.47\%

The local softball field has a lemonade stand. The graph shows the amount of money in the cash register of the lemonade stand.
Alexxandr [17]

1.

<h3>The y-intercept</h3>

The y-intercept is $35.

The y-intercept of a straight line graph is the point at which the graph intercepts the y-axis.

So, from the graph, the y-intercept is $35.

2.

<h3>The meaning of y-coordinate</h3>

The y-coordinate of the y-intercept of the function represents the amount of money present at the beginning of the sale when no cups where sold.

Since the y-intercept represents the point at which the graph intercepts the y-axis and then the x- value is zero, the y-coordinate of the y-intercept of the function represents the amount of money present at the beginning of the sale when no cups where sold.

The y-coordinate of the y-intercept of the function represents the amount of money present at the beginning of the sale when no cups where sold.

3.

<h3>The slope</h3>

The slope is 2.5

Since we are given two points on the line, the slope m of a line given two points (x₁, y₁) and (x₂, y₂) is m = (y₂ - y₁)/(x₂ - x₁).

From the graph, (x₁, y₁) = (3, 42.5) and (x₂, y₂) = (9, 57.5)

So, substituting these values into the equation for m, we have

m = (y₂ - y₁)/(x₂ - x₁)

m = (57.5 - 42.5)/(9 - 3)

m = 15.0/6

m = 2.5

The slope is 2.5

4.

<h3>Meaning of the slope</h3>

The slope represents the rate at which the lemonade is sold

Since the y-axis represent the amount of money in the cash register and the x-axis represents the number of cups of lemonade sold, the slope represents the rate at which the lemonade is sold.

The slope represents the rate at which the lemonade is sold
