Mrac [35]2 years ago
6 0

Answer:

They are not equal.

\frac{83}{100}< \frac{5}{6}

Step-by-step explanation:

0.83 =

\frac{83}{100}

\frac{83}{100}   >,

LCM of 100 and 6

300

\frac{83}{100}=\frac{249}{300}

\frac{5}{6} =\frac{250}{300}

\frac{249}{300}

The area of a quarter’s face is 4.64 cm2. The amount of space that it occupies is 0.60 cm3. Approximately how thick is a quarter
Greeley [361]
A quarter resembles a 3D figure of a cylinder. The face is the area of the base of the cylinder and the space it occupies is the volume of the cylinder. We need to find out the height of the cylinder.

Volume = Area of base•height
Volume/Area of base=height
0.60/4.64=0.12931
Round to the nearest hundred
height=0.13 cm

The initial temperature of a cup of tea is 200ºF. The surrounding temperature is 70ºF, and the value of the constant k is 0.6. A
Mazyrski [523]
Newton's cooling model is ΔT = ΔTo * e ^ (-k t)

ΔTo = 200°F - 70°F = 130°F

k = 0.6

t = 2 hours

=> ΔT = 130 * e ^ (-0.6 t) = 130 * e^ (-0.6 * 2) = 130 * e ^ (-1.2)

ΔT = 39.15°F

ΔT = T - Tenvironment => T = ΔT + Tenvironment = 39.15°F + 70°F = 109.15°F ≈ 109 °F.

Answer: T = 109 °F

The cloth top of the gazebo in Mr. Chang’s backyard has ripped from weathering. He needs to know the area of the cloth so he can
antoniya [11.8K]

Answer:

<u>The correct answer is A. 60 square feet.</u>

Step-by-step explanation:

1. Let's review the data provided to us for solving the question:

The gazebo in Mr. Chang's backyard, according to the figure, is a square pyramid because its base is a square of 6 feet as length of its sides.

Length of the sides of the base = 6 feet

Slant length = 5 feet

Height = 4 feet

2. How much cloth, in square feet, will Mr. Chang need, assuming he does not need to replace the cloth at the bottom of the figure?

Area of a square pyramid = Base area + 1/2 Perimeter * Slant length

Replacing with the real values, we have:

Area of a square pyramid = 6 * 6 + 1/2 (6 + 6 + 6 + 6) * 5

Area of a square pyramid = 36 + 1/2 (24) * 5

Area of a square pyramid = 36 + 12 * 5

Area of a square pyramid = 36 + 60

Area of a square pyramid = 96 feet ²

3. But remember than Mr. Chang doesn't need to replace the cloth at the bottom of the gazebo.

So we need to subtract the area of the base to the area of the square pyramid:

Area of the square pyramid - area of the base

Area of the base = 6 * 6 = 36 feet ²

96 feet ² - 36 feet ² = 60 feet ²

<u>The correct answer is A. 60 square feet.</u>

If u(x)=-2x^2+3 and v(x)=1/x what is the range of (u*v)(x) **the picture should help
nasty-shy [4]
We have that
u(x)=-2 x^{2} +3 \\ \\ v(x)= \frac{1}{x}
u(v(x))=u( \frac{1}{x})=-2( \frac{1}{x} )^{2}  +3 \\ u( \frac{1}{x})= \frac{(3 x^{2} -2)}{ x^{2} }

using a graph tool
see the attached figure

The horizontal asymptote of this function is at <span>y=3</span><span>.
So,
the range of this function is from </span><span>(−∞,3<span>)</span></span>
