Answer:

  • 8.4 miles

Step-by-step explanation:

Let the speed in the morning be s, then in the evening it is s - 4

<u>The distance is equal both directions:</u>

  • 45 min *s = 1 hr 10 min *(s - 4)

<u>Time in hours:</u>

  • 45*1/60*s = (1 + 10*1/60)(s - 4)
  • 3/4s = 7/6s - 7/6*4

<u>Multiply all terms by 12 to clear fraction:</u>

  • 9s = 14s - 56
  • 5s = 56
  • s = 56/5
  • s= 11.2 mph

<u>The distance is:</u>

  • 3/4*11.2 = 0.75*11.2 = 8.4 miles

The quadrilateral shown is a parallelogram. If m∠ADC = 125° and m∠1 = 30°, what is m∠2? A) 15° B) 25° C) 35° D) 55°
Ganezh [65]

Answer:

B) 25°

Step-by-step explanation:

Assuming the quadrilateral is the one shown in the picture attached, then a triangle ADC is form, where m∠ADC = 125° and m∠1 = 30°. The addition of the three angles of a triangle is equal to 180°, so:

m∠ADC + m∠1 + m∠2 = 180°

Replacing with the known values and isolating m∠2 we get:

125° + 30° + m∠2 = 180°

m∠2 = 180° - 125° - 30°

m∠2 = 25°

CAN SOMEONE HELP ME ASAP? The density of a certain material is such that it weighs 7 ounces for every 2.5 gallons of volume. Exp
lesya [120]

Answer: Density = 0.23 tons per cubic meter.

Step-by-step explanation:

Formula : Density=\dfrac{Mass(in \ ton)}{Volume (in\ m^3)}

1 ton = 32000 ounces

⇒ 1 ounce = 0.00003125 ton

⇒  7 ounces = 7(0.00003125)=  0.00021875 ton

1 gallon = 0.00378541 cubic meter

2.5 gallons = 0.009475 cubic meter

Density= \dfrac{0.00021875}{0.009475}\text{ tons per cubic meter}

\dfrac{21875}{94750}\text{ tons per cubic meter}\approx0.23\text{ tons per cubic meter}

Hence, Density = 0.23 tons per cubic meter.
