Answer:

4.5cm^2

Step-by-step explanation:

To find area of a triangle the formula is --> 1/2 base times height

so 3cm x 3cm = 9cm and divide by 2 --> 4.5 cm^2

write the slope intercept equation. the graph of f passes through (-6,4) and is perpendicular to the line that has an x-intercep
Nimfa-mama [501]

Answer:

y = -\frac{1}{3} x + 2

Step-by-step explanation:

The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:

Slope(s) = Change in y ÷ change in x

s = \frac{0 - -6}{2 - 0} = 3

The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = -\frac{1}{3}

Reason: The product of slopes of lines perpendicular to each other have to be -1

So the slope of the perpendicular line that passes through (-6,4) is -\frac{1}{3}

As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x

Taking another point (x,y) on the line,

-\frac{1}{3} = \frac{y - 4}{x - -6}

-\frac{1}{3} = \frac{y - 4}{x + 6}

y - 4 = -\frac{1}{3}x - 2

y = -\frac{1}{3}x + 2

34kurt

Answer:

250 bags

Step-by-step explanation:

Spring 3:7

       150:x

3x = 1050

x = 350 bags in spring

Total order = 150 + 350 = 500

Holiday Season 5:5

(5+5)x = 10x = 500

x = 50

5 * 50 = 250 bags

Please help me!! This is math 7th grade
Musya8 [376]

Answer:

14) false

15) false

Step-by-step explanation:

14) 120% of a positive whole number is always greater than the number. If the number is 1, 120% of it would give us 1.2 which is greater than 1. However if the number is a negative whole number, 120% of it would give us a smaller number. Let's try -1. 120% of -1 would give us -1.2, which is smaller than -1. Hence the statement is false.

15) 0.5% of a number is 0.5/100 of the number so we should multiply the number by 5/1000. 5/100 is only 5% of the number. Hence the statement is also false.
