How many times greater is 8.4x10^4 than 2.1x10^2

Answer:

[tex] 158.256 \: {cm}^{3} [/tex]

Step-by-step explanation:

For cylindrical jar:

Diameter = 6 cm

Radius (r) = 6/2 = 3 cm

Height (h) = 8 cm

[tex]V_{cylindrical \: jar} = \pi {r}^{2} h \\ \\ = 3.14 \times {(3)}^{2} \times 8 \\ \\ = 3.14 \times 72 \\ \\ = 226.08 \: {cm}^{3} \\ \\ \because \: jar \: is \: filled \: upto \: 70 \% \\ \\ \therefore \: V_{jam} = 70 \% \: of \: V_{cylindrical \: jar} \\ \\ \therefore V_{jam} = 0.70 \times 226.08 \\ \\ \therefore V_{jam} = 158.256 \: {cm}^{3} [/tex]

Answer:

[tex]Range= \{1,-4,-19\}[/tex]

Step-by-step explanation:

Given

[tex]f(n) = -4n - 3[/tex]

[tex]n = \{-1,1/4,4\}[/tex] --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

[tex]n = -1[/tex]

[tex]f(-1) = -4 * -1 - 3 =4 - 3 = 1[/tex]

[tex]n = 1/4[/tex]

[tex]f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4[/tex]

[tex]n=4[/tex]

[tex]f(-1) = -4 * 4 - 3 =-16 - 3 = -19[/tex]

Hence, the range is:

[tex]Range= \{1,-4,-19\}[/tex]

Answer:

94.2 ft of fencing

Step-by-step explanation:

To answer this, find the circumference, C, of the garden, using the circumference formula C = 2(pi)r.

Here, with r = 15 ft, we get C = 2(3.14)(15 ft) = 94.2 ft of fencing will enclose this garden.

Answer:

  x = y = (√10)/2

Step-by-step explanation:

In an isosceles right triangle, the side lengths are equal, and they are equal to (√2)/2 times the hypotenuse length.

  x = y = (√5)(√2)/2

  x = y = (√10)/2

Answer:

x = y = [tex]\frac{1}{2}[/tex] [tex]\sqrt{10}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex]

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{\sqrt{5} }[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )

2x = [tex]\sqrt{10}[/tex] ( divide both sides by 2 )

x = [tex]\frac{1}{2}[/tex] [tex]\sqrt{10}[/tex]

Since the base angles are 45° then the triangle is isosceles with both legs congruent , thus

x = y = [tex]\frac{1}{2}[/tex] [tex]\sqrt{10}[/tex]

[tex] \frac{140x}{140} = \frac{8400}{140} [/tex]

[tex]x = 60[/tex]

Our answer is 60.

Good luck.

Answer:

140 x X =8400

X=8400/140

X= 60

140 x 60 =8400

Answer:

Option (3)

Step-by-step explanation:

Steven has created a box plot to record the number of students who attended the science club meeting.

In a box plot, initial dot represents the minimum number and extreme point represents the maximum number.

From the graph attached,

Maximum number of students who attended the meeting are 32.

Therefore, Option (3) will be the correct option.

.Answer:

The answer is .31

Step-by-step explanation:

When there is a “th” at the end of the number it signals that the number is to the right of the decimal.

Tenths are immediately to the right of the decimal, next is hundredths, then thousandths, and so on.

Answer: C

Step-by-step explanation:

Answer:

V = 125 in^3

Step-by-step explanation:

A cube has 6 sides, and the area of each is equal to the side length squared:

A = 6x^2

A is given as 150 cm^2, and so is equal to 6x^2.  Thus, x = the side length = 5 cm.

The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3

Answer:

a

Step-by-step explanation:

To prove congruence

1 ∠ A ≅ ∠ C → given

2 ∠ DEA ≅ ∠ BEC → vertically opposite angles

3. AE ≅ EC → given

We then have 2 angles and the included side ( side between the 2 angles )

congruent in both triangles, thus Δ AED ≅ Δ CEB ( ASA postulate )

Zoes' error was in assuming ∠ DEA ≅ ∠ BEC was given

Zoe used an invalid reason to justify the congruence of a pair of sides or angles.

Option a is correct.

From given diagram it is observed that,

Line segment AD and CB are parallel and AC is transversal line. So that alternate angles A and C are equal.

                            [tex]\angle A=\angle C[/tex]

When two lines intersect at any point then vertically opposite angles are equal.

So that,          [tex]\angle DEA=\angle BEC[/tex]

Given that ,   [tex]AE=EC[/tex]

The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

Hence, both triangles are congruent to each other.

Answer: SA≈27.1.

The formula is SA=2πrh+2πr2.

The radius is 0.75 since 1.5 divided by 2=0.75.

Plug it in.

Answer:

0.54 or 54%

Step-by-step explanation:

P( 1st but not second) = P(1st) - P(1st and Second) = 0.4 - 0.28 = 0.12 = 12%

P( 2nd but not first) = P(2nd) - P(1st and Second) = 0.7 - 0.28 = 0.42 = 42%

Probability of 1 of them (exactly one) = P( 1st but not second) + P( 2nd but not first) = 0.12 (12%) + 0.42 (42%) = 0.54 or also 54%.

Hope this helps!
