I'll help with a few because no-one wants to just do your homework

there is the formula way or the intuitive way

(-19, -2) (-17, -10)

now slope is (difference in y)/ (difference in x)

(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x

formula way:

(-19, -2) (-17, -10)

(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula

(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2

intuitive way

(-19, -2) (-17, -10)

(difference in y)/ (difference in x)

lets looks at the ys

-2 and -10; how many steps from -2 to -10? -8 the diff in y

lets looks at the xs

-19 to -17; how many steps from -19 to -17? + 2 the diff in x

so its -8/2

You have to make 1000 buttons.the diameter of the button is 9cm but you have to find it’s area.its $15/m squared and you have to

Semmy [17]

Answer:

$95.38

Step-by-step explanation:

step 1

Find the area of one button

The area is equal to

$A=\pi r^{2}$

we have

$r=9/2=4.5\ cm$ ---> the radius is half the diameter

Convert to meters

$r=4.5\ cm=4.5/100=0.045\ m$

assume

$\pi =3.14$

substitute

$A=(3.14)(0.045)^{2}\\A=0.0063585\ m^2$

step 2

Find the area of 1,00 buttons

Multiply by 1,000

$A=0.0063585(1,000)=6.3585\ m^2$

step 3

Find the cost

Multiply $15 per square meter by the total area of 1,000 buttons

$(15)6.3585=\$95.38$

Beaker A contains 1 liter which is 15 percent oil and the rest is vinegar, thoroughly mixed up. Beaker B contains 2 liters which

Tanzania [10]

Answer:

Add 1.25 litres of oil.

Step-by-step explanation:

Contents in beaker A implies;

15% of oil in 1 litre = 0.15 litres of oil

So that, there are 0.15 litres of oil and 0.85 litres of vinegar in beaker A.

Contents in beaker B implies:

55% of oil in 2 litres = 1.1 litres of oil

So that, thee are 1.1 litres of oil and 0.9 litres of vinegar in beaker B.

Half of contents of B poured into A implies that beaker A now contains:

0.15 litres + 0.55 litres = 0.7 litres of oil

0.85 litres + 0.45 litres = 1.3 litres of vinegar

The percentage of oil in A now = $\frac{0.7}{2}$ x 100%

= 35%

To increase the percentage of oil to 60%, then:

0.7 litres + 1.25 litres = 1.95 litres of oil

But the new total litres of the content in beaker A = 3.25 litres

So that;

$\frac{1.95}{3.25}$ x 100% = 60%

Therefore, to produce a mixture which is 60% oil, add 1.25 litres of oil.

100 POINTS!!! Please solve this question step by step and explain each step for 100 points.

djverab [1.8K]

$2\dfrac 29 = -\dfrac 45 m \\\\\implies 2+ \dfrac 29 =- \dfrac 45 m \\\\\implies \dfrac{20}9 = -\dfrac 45 m \\\\\implies 5(20) = (-4m)9\\\\\implies 100 = -36m\\\\\implies m = -\dfrac{100}{36} \\\\\implies m = -\dfrac{25}9\\\\\implies m=-2\dfrac 79$
