Answer:

  yes

Step-by-step explanation:

If GH║FE, then ∆DEF ~ ∆DHG.

In similar triangles, corresponding sides have the same ratios.

The ratios of corresponding sides are ...

  DG/DF = DH/DE

  DG/(DG + GF) = 18/(18+36)

  (1/2GF)/((1/2GF +GF) = 1/3

  (1/2)/(3/2) = 1/3

  1/3 = 1/3

Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.

Please help me with this math problem. Find the equation for the line below.
lora16 [44]

Answer:

y+2=3/4(x+5)

Step-by-step explanation:

The first step is to find the slope of the line. Between the two points, the line rises from a y value of -2 to a y value of 4, or a total rise of 6 units. It also goes to the right from an x value of -5 to an x value of 3, which is a total of 8 units. 6 units of rise over 8 units of run is a total slope of 6/8=3/4. Now, you can use the point slope form for either one of the points (I'll use the leftmost one).

y+2=3/4(x+5)

Hope this helps!

Suppose the adult population of Micronesia is 100,000 people. Of these 100,000 people, 20,000 are not in the labor force. Of the
QveST [7]

Answer:

b. 6.25%

Step-by-step explanation:

In order to obtain the unemployment rate in Micronesia, you have to divide the amount unemployees that still in the labor force between the amount of people in the labor force.

The labor force is defined as the number of people employed plus the unemployed people who are seeking work.

The number of people employed is the people who work part time plus the people who are fully employed (the remainder of the 80,000 people). Therefore:

14,000 + (80,000 -16,000 - 4,000 - 14,000)

14,000+46,000=60,000

The number of unemployed people who are seeking work is:

4,000

The labor force is:

60,000 + 4,000 = 64,000

The unemployment rate is:

4,000/64,000 = 0.0625

Multiplying by 100 to obtain the percentage:

0.0625(100)=6.25%

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?
Hunter-Best [27]
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.

c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet
