A and B are similar cuboids.
surface area of A: surface area of B = 25 : 36
Work out volume of A: volume of B
A 5:6
B 125 : 216
C 25 : 36
D 625 : 1296​

Answers

Answer:

B. 125 : 216

Step-by-step explanation:

Surface area of cuboid A with side a is:

6a²

Same for cuboid B with side b:

6b²

Ratio of surface areas:

6a² : 6b² = 25 : 36 ⇒a² : b² = 25 : 36 ⇒a : b = 5 : 6

Volumes of A and B are:

a³ and b³

And their ratio is:

a³ : b³ = 5³ : 6³  ⇒a³ : b³ = 125 : 216

Correct option is B

Answer:

B. 125 : 216

Determine three ways to have 4 more dimes than nickels:

Who can solve this for me?

Answers

Answer:

x=2 and y=6

Step-by-step explanation:

thee isn't any other way im sorry but there isn't here is a list:

1 nickel = $0.05 and 5 dimes =$0.50 = $0.55

2 nickels = $0.10 and 6 dimes = $0.60 = $0.70

3 nickels = $0.15 and 7 dimes = $0.75 = $0.85

4 nickels = $0.20 and 8 dimes = $0.80 = $1.00

5 nickels equal $0.25 and 9 dimes equals $0.90 = $1.15

so as you can see the more you add the higher the number gets and if its any lower it won't be enough sorry if you really needed that last part

slope intercept form  =>   Y = mx + b  

find m... the slope by using any two points on the line

p1 = (0,5)  by inspection

p2=(4,6)  by inspection

find m  = y2-y1 / x2-x1

      m   = 6 - 5 / 4 - 0  

      m    =1 / 4

then use the slope intercept formula

y = 1/4x + 5      for your answer.  we know b = 5 b/c thats where the line crosses the y axis.

y = [tex]\frac{1}{4}[/tex]x + 5    is the answer

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d
from the source of the sound.
A person 14 feet from a jetski, it is 85 decibels loud.
How loud is the jetski when the person is 41 feet away? (Round to 3 decimal places.)
dB

Answers

Answer:

L = 9.91 decibels.

Step-by-step explanation:

The loudness, L is inversely proportional to the square of the distance, d, from the source of the sound.

i.e L [tex]\alpha[/tex] [tex]\frac{1}{d^{2} }[/tex]

L = [tex]\frac{k}{d^{2} }[/tex]

Where k is the constant of proportionality.

When d = 14 feet and L = 85 dB, then;

k = L x [tex]d^{2}[/tex]

  = 85 x [tex](14)^{2}[/tex]

 = 16660

k = 16660

L = [tex]\frac{16660}{d^{2} }[/tex]

Thus, when d = 41 feet, then;

L = [tex]\frac{16660}{(41)^{2} }[/tex]

  = [tex]\frac{16660}{1681}[/tex]

  = 9.91077

L = 9.91 dB

The loudness is 9.91 decibels.

Answers

Step-by-step explanation:

5 = x + 3. The product of 2 times a number is 10. 2x = 10. One half a number is 10 x/2 = 10. Five times the sum of x and 2 5(x + 2). Seven is greater than x.

Answer:

35

Step-by-step explanation:

This is how you can solve for the missing number that is doubled: ( x )

7 = 3 + 2x

7 ( -3 ) = 3 ( -3 ) + 2x

4 = 2x

4 ( /2 ) = 2x ( /2 )

2 = x

This is how you solve for the number the question is asking for: ( y )

y = 5 ( 3 + 2x )

y = 5 ( 3 + 2 ( *2 ))

y = 5 ( 3 + 4 )

y = 5 ( 7 )

y = 5 * 7

y = 35

Mario compared the slope of the function graphed below to the slope of the linear function that has an x-intercept of 1 and a y-intercept of -2.


Find the slope of both lines. In the answer box give the slope of the steeper line.

Answers

Answer:

The linear equation in the slope-intercept form will be:

[tex]y\:=\:\frac{2}{3}x+64[/tex]

Step-by-step explanation:

From the line graph, taking two points

(21, 78)(27, 82)

Finding the slope between (21, 78) and (27, 82)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(21,\:78\right),\:\left(x_2,\:y_2\right)=\left(27,\:82\right)[/tex]

[tex]m=\frac{82-78}{27-21}[/tex]

[tex]m=\frac{2}{3}[/tex]

We know that the slope-intercept of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

substituting (21, 78) and m = 2/3 in the slope-intercept of the line

[tex]y = mx+b[/tex]

[tex]78=\frac{2}{3}\left(21\right)+b[/tex]

switch sides

[tex]\frac{2}{3}\left(21\right)+b=78[/tex]

[tex]14+b=78[/tex]

[tex]b=64[/tex]

substituting b = 64 and m = 2/3 in the slope-intercept of the line

[tex]y = mx+b[/tex]

[tex]y\:=\:\frac{2}{3}x+64[/tex]

Therefore, the linear equation in the slope-intercept form will be:

[tex]y\:=\:\frac{2}{3}x+64[/tex]

Step-by-step explanation:

Let x represent the amount to be added, in quarts. Then the amount of anti-freeze in the resulting solution is ...

  0.20(8) + 1.00(x) = 0.30(8 +x)

  0.70x = 0.10(8) . . . . . . subtract 0.20(8)+0.30(x)

Answer the following question please

Answers

Answer:

∠MON = 98°

Step-by-step explanation:

It is given that ∠LON is a straight line.

∠MON = 3x+89

and

∠LOM = 8x+58

If LON is a straight line. It means,

∠MON + ∠LOM = 180 (Linear pair)

Putting values,

3x+89 + 8x+58 = 180

11x + 147 = 180

11x = 180-147

11x = 33

x = 3

So, ∠MON = 3(3)+89

= 9+89

= 98

Hence, the value of ∠MON is equal to 98°.

(1 point) Find the size of the sample needed to estimate the difference between the proportions of boys and girls under 10 years old who are afraid of spiders. Assume that we want 9595% confidence that the error is smaller than 0.03.

Answers

Answer:

The size of the sample = 1088.90

Step-by-step explanation:

Given that:

The confidence interval level = 0.95

The margin of error = 0.03

Suppose the proportion of the boys and the girls are p₁ and p₂ respectively.

The Standard error S.E of difference is:

[tex]S.E (p_1-P_2) = \sqrt{ \dfrac{p_1(1-p_1) }{n} + \dfrac{p_2(1-p_2)}{n} }[/tex]

Assume p₁ = p₂ = 0.5

[tex]S.E (p_1-P_2) = \sqrt{ \dfrac{0.5(1-0.5) }{n} + \dfrac{0.5(1-0.5)}{n} }[/tex]

[tex]S.E (p_1-P_2) =\dfrac{0.70711}{\sqrt{n}}[/tex]

The z-critical value at 95% C.I = 1.96

Margin of error = Z_{critical} × S.E

[tex]0.03 = 1.96 \times \dfrac{0.70711}{\sqrt{n}}[/tex]

[tex]n =\dfrac{\left(1.96\ \cdot\ 0.70711^{2}\right)}{0.03^{2}}[/tex]

Make a table of values for f(x) after the given translation 3 units up

Answers

Answer:

In this case, we do not have the table, so i will answer in a general way:

First, let's describe the transformation.

Vertical shift.

If we have a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

This will move the graph of f(x) up or down a distance of N units.

if N is positive, then the shift is upwards

if N is negative, then the shift is downwards.

Then a shift of 3 units up, is written as:

g(x) = f(x) + 3

This would be translated to the table in the next way:

You need to add 3 to all the values of y (or f(x)) in the table:

So if for example, the original table was:

x            f(x)

0             5

1              7

2             10

3              15

The table of the transformation will be:

x              g(x)

0              5 + 3 = 8

1               7 + 3 = 10

2              10 + 3 = 13

3               15 + 3 = 18
