answer = not define

Step-by-step explanation:

slope = (y2- y1) / (x2- x1)

= 9-3 / 7-7

= 6/0

= not define

I think points are wrong

AB is congruent to DE because segment DE was constructed so that DE = AB. BC is congruent to EF because segment EF was construct

Alex Ar [27]

DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.

<h3>Congruent shape</h3>

Two shapes are said to be congruent if they have the same shape, all their corresponding angles and sides are congruent to one another.

Given that DE = AB and BC = EF.

In right triangle DEF, using Pythagoras:

DF² = DE² + EF²

Also, In right triangle ABC, using Pythagoras:

AC² = AB² + BC²

But DE = AB and EF = BC, hence:

AC² = DE² + EF²

AC² = DF²

Taking square root of both sides, hence:

AC = DF

Since DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.

Need help with this. Hope someone can help

To solve this problem, we must remember that the formula for volume is V = lwh, where l represents length, w represents width, and h represents height. Since we know the respective values for length, height, and volume, we can substitute those into the formula and then solve for the width, as modeled below:

30,000 cm³ = 30 cm * w * 500 mm

We must recognize first, though, that one of the values is given in millimeters, not centimeters. To continue solving this problem, we must convert this value to centimeters, using our knowledge that 1 cm = 10mm. This means that 500 mm = 50 cm, so we can substitute this into our equation below:

30,000 cm³ = 30 cm * w * 50 cm

To begin to solve this equation, we should first multiply all of the factors together on the right side of the equation, which gives us:

30,000 cm³ = 1,500w cm²

Next, we must divide both sides of the equation by 1,500 in order to get the variable w alone on the right side of the equation.

20 cm = w

Therefore, the width of the figure shown above is 20 cm.

Hope this helps!

Danny has a rectangular rose garden that measures 8m by 12.5m. One bag of fertilizer can cover 16m2 . How many bags will he need

mrs_skeptik [129]

Answer:

we will need 7 bags

Step-by-step explanation:

To solve this problem we first have to calculate the total area of the garden

a = area

b = base = 8m

h = height = 12.5m

a = b * h

we replace with the known values

a = 8m * 12.5m

a = 100m²

Now that we know the total area of the garden and the area occupied by a single bag, we divide the total area by what a bag covers.

100m² / 16m² = 6.25 bags

because we cannot buy a fraction of a bag we will need 7 bags
