The difference in area between the top surfaces of the two cakes is 28.26 inches²

where

r = radius

Therefore,

area of top layer = πr²

d = 2r

r = d / 2

r = 8 / 2

r = 4 inches

area of top layer = 3.14 × 4²

area of top layer = 3.14 × 16

area of top layer = 50.24 inches²

area of the bottom layer = πr²

r = 10 / 2 = 5 inches

area of the bottom layer = 3.14 × 5²

area of the bottom layer = 3.14 ×25

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval estimate for the mean number of calories for servings of breakfast cereals is (195.3, 215.7).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

From the sample and the significance level of 0.05, we have that the parameters are given by:

[tex]\overline{x} = 205.5, s = 14.2, n = 10, t = 2.2622[/tex]

Hence:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 205.5 - 2.2622\frac{14.2}{\sqrt{10}} = 195.3[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 205.5 + 2.2622\frac{14.2}{\sqrt{10}} = 215.7[/tex]

The 95% confidence interval estimate for the mean number of calories for servings of breakfast cereals is (195.3, 215.7).

Answer:

4h + 2c = 186 legs

Step-by-step explanation:

h is the number horses and c is the number of chickens.

We know that 1 horse = 4 legs.

And 1 chicjen = 2 legs

We can write these as:

1H = 4 legs

1C = 2 legs

We are told that a farmer counts 186 legs.  That must be represented by the equations:

4h + 2c = 186 legs

i just did this and i am right

Answer:

Step-by-step explanation:

The equation has infinitely many solutions if LHS and RHS are same regardless the value of the variable.

Let's simplify the LHS and make sure it is same as RHS.

Let the missing numbers are a and b.

Find a and b:

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{-8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{(-6)}}}{\underset{run} {\underset{x_2}{-2}-\underset{x_1}{1}}}\implies \cfrac{-8+6}{-3}\implies \cfrac{-2}{-3}\cfrac{2}{3}[/tex]

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-6)}=\stackrel{m}{\cfrac{2}{3}}(x-\stackrel{x_1}{1})\implies y+6=\cfrac{2}{3}x-\cfrac{2}{3}[/tex]

hmmm now let's put that in standard form, that is

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

[tex]\stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y+6)~~ = ~~3\left( \cfrac{2}{3}x-\cfrac{2}{3} \right)}\implies 3y+18~~ = ~~2x-2 \\\\\\ 3y=2x-20\implies -2x+3y=-20\implies 2x-3y=20[/tex]

Answer:

50 and 80

Step-by-step explanation:

two numbers are in ratio 5;8 which  is 5x + 8x

sum = 130

5x  + 8x  = 130

13x = 130   ( divide both sides by 13)

x = 10

to find the two numbers we multiply by x

5x  = 5 x 10   = 50

8x  =  8  x 10  = 80

Answer:

11 cm

formulae:

volume of cube: a³  [ where a is side length ]

solve:

side³ = volume

a³ = 1331

a = ³√1331

a = 11

Answer:

11 cm

Step-by-step explanation:

the volume (V) of a cube is calculated as

V = s³ ( s is the side length )

given V = 1331 cm³ , then

s³ = 1331 ( take cube root of both sides )

s = [tex]\sqrt[3]{1331}[/tex] = 11

Answer:

True: B, C, D, F, G

False: A, E

Step-by-step explanation:

The false statements are false because we don't know anything about the measures of the sides of the red and blue triangles.

We do know that EF which is vector v is the hypotenuse of a 3-4-5 triangle, And that triangle ABC and triangle A'B'C' are exactly the same shape and size. And that one slid (translation) down at the exact angle and direction of vector v...so all the points, parts, sides, pieces of the triangle slid down in the same angle and direction.

Answer:

75% of x

Step-by-step explanation:

Answer:

75%x (or 0.75x)

Step-by-step explanation:

We can convert the percentages to decimal format and then multiply.

50%  = 0.50

150% = 1.50

"50% of 150% of x" can be written as:

(0.50)(1.50)x

= 0.75x

50% of 150% of x is 75%x
