Can somebody help me with my geometry?
ahrayia [7]
The slope of AC is -0.4

Proof:
In triangles ABC and DBE,
∠DBE is common to both triangles.
AB = 2DB (D is the midpoint of the interval AB)
Also, BC = 2BE (E is the midpoint of the interval BC)

Thus triangles ABC and DBE are similar in the ratio 2:1

Since, they are similar, ∠BDE must equal ∠BAC (corresponding angles in similar triangles)

If ∠BDE = ∠BAC, DE must be parallel to AC (corresponding angles are equal along parallel lines)
Thus, the slope of AC = the slope of DE
Thus, the slope of AC is -0.4

A 25-kilogram (245-newton) bag of sugar is lifted 3 meters. Determine the work done.
solong [7]
The answer is  735 J

<span>A work (W) is a product of a force (F) and a distance (d):
W = F · d
</span>
W = ?
F = 245N 
d = 3m

W = 245N * 3m
W = 735 J

The temperature of a city changed by -20°C over a four week. If the temperature changed by the same amount each week write an ex
andre [41]

Answer:

A)  T=\frac{-20}{4}

B) T = -5 °C

Step-by-step explanation:

A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

T=\frac{-20}{4}

B) In order to simplify the expression, simply perform the division.

T=\frac{-20}{4}\\T=-5^oC

This means that the temperature has dropped by 5 degrees each week.

Geometry: Use this illustration to calculate these values, ASAP!!!

Applying the same-side interior angles theorem,

7. m∠4 = 50°; m∠5 = 130°

8. m∠2 = 15°; m∠8 = 15°.

<h3>What is the Same-Side Interior Angles Theorem?</h3>

The same-side interior angles theorem holds that, two interior angles on a side of a transversal are supplementary, that is they add up to 180 degrees.

<h3>What is the Alternate Exterior Angles Theorem?</h3>

According to the alternate exterior angles theorem, exterior angles that alternate each other along a transversal are congruent, that is they have equal measures.

7. m∠4 + m∠5 = 180 [same-side interior angles theorem]

Substitute

y + 2y + 30 = 180

3y + 30 = 180

3y = 180 - 30

3y = 150

y = 50

m∠4 = y = 50°

m∠5 = 2y + 30 = 2(50) + 30

m∠5 = 130°

8. m∠2 = m∠8 [alternate exterior angles theorem]

Substitute

x - 30 = 3x - 120

x - 3x = 30 - 120

-2x = -90

x = 45

m∠2 = x - 30 = 45 - 30 = 15°

m∠8 = 3x - 120 = 3(45) - 120 = 15°
