Answer:

Step-by-step explanation:

The shape of the container isn’t changing here, so the height of the water will be proportional to the volume. 75 cm^3 is ¾ of 100 cm^3, so the water will rise ¾ as high.

¾ of 8 cm is 6 cm.

Find the equation of the line passing<br> through the points (2, 4) and (3, 2).<br> y = [? ]x + [ ]
PtichkaEL [24]

Answer:

first find slope m

m=(4-2)/(2-3)

m= -2

so equation line is

y-y1=m(x-x1)

y-4=-2(x-2)

y-4=-2x+4

y=-2x+4+4

y=-2x+8

?=-2

What is the area of this figure? Please help.
Ad libitum [116K]

The area of the composite figure can be found by summing the whole area that made up the figure. Therefore, the area of the figure is 213.5m²

<h3>Area of a composite figure</h3>

The area of the composite figure is the sum of the area of the whole figure.

Therefore, the composite figure can be divided into 2 triangles and two rectangles.

Hence,

area of triangle1 = 1 / 2 × 10 × 13 = 65 m²

area of the triangle2 = 1 / 2 × 15 × 7 = 52.5 m²

area of the rectangle1 = 8 × 3 = 24 m²

area of rectangle2 = 7 × 6 = 42 m²

area of rectangle3 = 5 × 6 = 30 m²

Therefore,

area of the composite figure = 65 + 52.5 + 24 + 42 + 30 = 213.5 meters squared

I need help lol I’m taking this test
Vera_Pavlovna [14]

Answer:

A) T = -1.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10t+4−2t=2−2(t+4)

10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)

10t+4+−2t=2+−2t+−8

(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)

8t+4=−2t+−6

8t+4=−2t−6

Step 2: Add 2t to both sides.

8t+4+2t=−2t−6+2t

10t+4=−6

Step 3: Subtract 4 from both sides.

10t+4−4=−6−4

10t=−10

Step 4: Divide both sides by 10.

Hope this helps!

The population of Portland Oregon has recently grown to more than 500,000. What is the order of magnitude for the number of peop
miss Akunina [59]

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

P=500,000

It contains 6 zeroes. It means,

P=5\times 10^6

So, the order of magnitude for the number of people in Portland is 6.
