Answer:

144 square centimeters

Step-by-step explanation:

So the first triangle, which is on the side. We do 3 x 4, which is 12. We would normally divide it by 2 since it is a triangle, but since there is 2 triangles that are the same, we keep it 12. Next, we have the bottom rectangle. We do 4 x 11, which is 44. Next we do the top rectangle, 5 x 11, which is 55. Next we do the side rectangle, 3 x 11, which is 33.

Next we add all of these answers together!

12 + 44 = 56

56 + 55 = 111

111 + 33 = 144

Dafna1 [17]

Answer:

y = 18x + 10

slope = 18

y-intercept = 10

Step-by-step explanation:

The situation given in the problem is linear and can be represented using slope-intercept form of a linear equation: y = mx + b, where 'm' is equal to the slope, 'b' is equal to the y-intercept, 'x' is the number of hours and 'y' is the total number of miles.

Given that Jasmine has already biked 10 miles, her initial value, or y-intercept would be 10. Since she is now biking at a rate of 18 miles per hour, her rate of change, or slope, would be 18.

Using these values for 'm' and 'b': y = 18x + 10

What is 3 1/3 -1 1/2 as a fraction?

eduard

Answer:

11/6

Step-by-step explanation:

Step 1: Convert to Improper fractions

3 1/3 = 3*3/3 + 1/3 = 9/3 + 1/3 = 10/3

1 1/2 = 1*2/2 + 1/2 = 2/2 + 1/2 = 3/2

Step 2: Make common denominators

10/3 * 2/2 = 20/6

3/2 * 3/3 = 9/6

Step 3: Subtract

20/6 - 9/6

11/6

Answer: 11/6
