  • As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in temperature.
  • While 95°F is the best temperature for yeast to multiply, that's not quite warm enough for proofing active dry yeast. It needs the extra warmth to dissolve and become active. At cooler temperatures, the yeast doesn't wake up as well, and it can release a substance that can interfere with gluten formation.
  • Factor 1: Temperature. Yeast is extremely sensitive to temperature.
  • Factor 2: Time. The longer the yeast is allowed to work, the more gas is created.
  • Factor 3: Quantity of Yeast.
  • Factor 4: Quantity of Water.
  • Factor 5: Salt.  Pour in about 1 tablespoon of yeast and gently shake the bottle up a little bit. Add a teaspoon of sugar and swirl the bottle around a little more. Slide the neck of the balloon over the opening of the bottle. Let the yeast work its magic for about 15-20 minutes.
  • As the yeast feeds on the sugar, it produces carbon dioxide gas. This process is known as fermentation. The trapped CO2 accumulates inside the balloon, slowly inflating it.

The area of a triangle is 22 yd with a base of 8 years. What is the height, in yards?
cluponka [151]
The area of a triangle can be found using the formula 1/2*b*h

We can substitute what we know in now, 22 = 1/2*8*h

22 = 4*h
22 = 4*5.5

The answer would be 5.5 yards

I hope this helps!

A spacecraft is traveling with a velocity of v0x = 5320 m/s along the +x direction. Two engines are turned on for a time of 739
OlgaM077 [116]

Answer:

The velocities after 739 s of firing of each engine would be 6642.81 m/s in the x direction and 5306.02 in the y direction

Step-by-step explanation:

  1. For a constant acceleration: v_{f}=v_{0}+at, where  v_{f} is the final velocity in a direction after the acceleration is applied, v_{0} is the initial velocity in that direction  before the acceleration is applied, a is the acceleration applied in such direction, and t is the amount of time during where that acceleration was applied.
  2. <em>Then for the x direction</em> it is known that the initial velocity is v_{0x} = 5320 m/s, the acceleration (the applied by the engine) in x direction is a_{x} 1.79 m/s2 and, the time during the acceleration was applied (the time during the engines were fired) of the  is 739 s. Then: v_{fx}=v_{0x}+a_{x}t=5320\frac{m}{s} +1.79\frac{m}{s^{2} }*739s=6642.81\frac{m}{s}
  3. In the same fashion, <em>for the y direction</em>, the initial velocity is  v_{0y} = 0 m/s, the acceleration in y direction is a_{y} 7.18 m/s2, and the time is the same that in the x direction, 739 s, then for the final velocity in the y direction: v_{fy}=v_{0y}+a_{y}t=0\frac{m}{s} +7.18\frac{m}{s^{2} }*739s=5306.02\frac{m}{s}

an electronics company is designing a watch with a face that is in the shape of a hexagon and two congruent trapezoids attached.
nalin [4]

The total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²

Since an electronics company is designing a watch with a face that is in the shape of a hexagon and two congruent trapezoids attached. The heights of the trapezoids and the apothem of the hexagon measure 2 centimeters each, and the length of the shorter base of each trapezoid is 1.5 centimeters, the radii of the hexagon, and the base of the trapezoid form a triangle of

  • height, h = apothem of the hexagon = 2 cm and
  • base, b = length of shorter base of trapezoid.
<h3>Area of the triangle</h3>

So, the area of this triangle is A = 1/2bh

= 1/2 × 1. 5 cm × 2 cm

= 1.5 cm × 1 cm

= 1.5 cm²

<h3>Area of the hexagon</h3>

Since there are 6 of such triangles in the hexagon, the area of the hexagon, A' = 6A

= 6 × 1.5 cm²

= 9.0 cm²

So, the total area of the face of the watch to the nearest tenth of a square centimemter is 9.0 cm²
