Answer:

1080

Step-by-step explanation:

480 + 480 + 1/4(480) = 1080

Answer:

1080 postcards

Step-by-step explanation:

WIth 2 full albums you take 480 and multiply it by 2 to get 960 and 1/4 of 480 is 120 because we divide 480 by 4 to get that and if we add 120 to 960 we get 1080.

Answer:

A. (y - 2) = 3/2 ( x + 1)

Explanation:

The point-slope formula is ( y - y1) = m ( x - x1). Just distribute the given where m is 3/2, x1 = - 1 and y1 = 2.

Answer:

Step-by-step explanation:

1. x is the hypotenuse of a right triangle with legs 4.4 and 8.3. The Pythagorean theorem can be used.

  x² = 4.4² +8.3² = 19.36 +68.89 = 88.25

  x = √88.25 ≈ 9.394

  x = 9.4 . . . . rounded to tenths

2. The product of segment lengths to the near and far circle intercept is the same for both secants.

  7(7+11) = 6(6+x)

  7(18)/6 = 6 +x . . . . . divide by 6

  21 -6 = x = 15 . . . . . subtract 6

Step-by-step explanation:

2) 22+140= 162

180-162= 18

x=18

(180 ‘cuz that’s the full angle of a triangle)

David spent 60% of his money which was in his wallet.

Answer:

well the highest number you could get in a dice is 6 and the lowest is a 1

6=100%

5=85%

4=65%

3=45%

2=25%

1=5%

so the % chance of you getting a 4 or 5 is around 70%

Applying Euler's method:

Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:

[tex]\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}[/tex]

[tex]\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}[/tex]

For step size h = 0.1, we can approximate y (1.2) with just 2 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8[/tex]

[tex]\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}[/tex]

For step size h = 0.05, we need 4 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4[/tex]

[tex]\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895[/tex]

[tex]\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075[/tex]

[tex]\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}[/tex]

(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)

Answer:

A. Area of ABCD = 240 [tex]cm^{2}[/tex]

B. 60 cm

C. 36 cm

D. 50 cm

Step-by-step explanation:

Given: AB = 24cm BC = 10cm and AE = 13cm.

A.  Since a rectangle is a 2 dimensional figure, it has no volume but area.

So that,

the area of the rectangle ABCD = length x width

                                                     = 24 x 10

                                                     = 240 [tex]cm^{2}[/tex]

B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.

[tex]BD^{2}[/tex] = [tex]BC^{2}[/tex] + [tex]DC^{2}[/tex]

       = [tex]10^{2}[/tex] + [tex]24^{2}[/tex]

       = 676

BD = [tex]\sqrt{676}[/tex]

     = 26

BD = 26 cm

so that,

the circumference of BCD = 10 + 24 + 26

                                         =   60 cm

C. To calculate the circumference of the BEC triangle,

AC = 26 cm, AE = 13 cm

CE = 26 - 13

     = 13 cm

CE = 13 cm

The circumference of the BEC triangle = 13 + 13 + 10

                                                                 = 36 cm

D. The circumference of the DEC triangle = 13 + 13 + 24

                                                                 = 50 cm

Answer:

Undefined.

Step-by-step explanation:

Slope is equal to the change in y over the change is x, or rise over run.

[tex]m=\frac{change in y }{ change in x}[/tex]

The change in x is equal to the difference in x-coordinates, and the chnage in y is equal to the difference in y-coordinates.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Substitute in the values of x and y into the equation to find the slope.

[tex]m= \frac{-2-(2)}{2-(2)}[/tex]

Simplify it. since -2-(2) and 2-(2) = nothing, the Slope is Undefined.

Hence, the slope is Undefined.

Answer:

Undefined

Answer:

volume for cube = length cubed I.e. 6x6×6 = 216

Answer:

You have an right angle which is like an L and is 90 degrees. A acute angle and it just like if you was to close a L just a little bit you would get an acute angle which is 30 degrees. Last you have the the obtuse angle it´s like is you pulled the top of L and pulled it back a little bit you would get that. I mean those are the basic angles.

Answer:

[tex]P(3) = 0.3397[/tex]

Step-by-step explanation:

The given details represent binomial distribution. So, we have:

[tex]n = 5[/tex]

[tex]p = 64\% = 0.64[/tex]

Required

Calculate P(3)

This is calculated using:

[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]

This gives:

[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]

[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]

[tex]P(3) = 0.3397[/tex]

Answer:

You have it correct, it is the 3rd one.

Step-by-step explanation:

The commutative property is the equation, flip-flopped. So, if you had 1+8 = 8+1, that would be right.

Answer:

3rd one.....

Step-by-step explanation:

Answer:

y=3x+12

y-12=3x

x=y/3 - 4

f(y)=y/3 - 4

or

f(x)=x/3 - 4

where f(x) is the inverse of y.
