Answer:

-1,512,390

Step-by-step explanation:

Given

a1 = 15

[tex]a_i = a_{i-1} -7[/tex]

Let us generate the first three terms of the sequence

[tex]a_2 = a_{2-1}-7\\a_2 = a_1 - 7\\a_2 = 15-7\\a_2 = 8[/tex]

For [tex]a_3[/tex]

[tex]a_3 = a_{3-1}-7\\a_3 = a_2 - 7\\a_3 = 8-7\\a_3 = 1[/tex]

Hence the first three terms ae 15, 8, 1...

This sequence forms an arithmetic progression with;

first term a = 15

common difference d = 8 - 15 = - -8 = -7

n is the number of terms = 660 (since we are looking for the sum of the first 660 terms)

Using the formula;

[tex]S_n = \frac{n}{2}[2a + (n-1)d]\\[/tex]

Substitute the given values;

[tex]S_{660} = \frac{660}{2}[2(15) + (660-1)(-7)]\\S_{660} = 330[30 + (659)(-7)]\\S_{660} = 330[30 -4613]\\S_{660} = 330[-4583]\\S_{660} = -1,512,390[/tex]

Hence the sum of the first 660 terms of the sequence is  -1,512,390

Answer:

BC = 36

Step-by-step explanation:

If <X ≅ <A, and <Y ≅ B, therefore ∆XYZ is similar to ∆ABC.

Since ∆XYZ is similar to ∆ABC, it follows that the ration of their corresponding side lengths would be equal.

That is:

[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]

AB = 15

XY = 5

YZ = 12

Thus:

[tex] \frac{AB}{XY} = \frac{BC}{YZ} [/tex]

Plug in the values

[tex] \frac{15}{5} = \frac{BC}{12} [/tex]

Multiply both sides by 12

[tex] \frac{15}{5}*12 = \frac{BC}{12}*12 [/tex]

[tex] \frac{15*12}{5} = BC [/tex]

[tex] 36 = BC [/tex]

The length of the segment BC is 36 and this can be determined by using similar triangle properties and the given data.

Given :

The following steps can be used in order to determine the length of the segment BC:

Step 1 - According to the given data, XY = 5 , YZ = 12 , and AB = 15. Also angle X congruent to angle A and angle Y congruent to angle B.

Step 2 - So, according to the given data, it can be concluded that both the triangles are similar.

Step 3 - From the above steps, it can be concluded that the corresponding sides ratios of the triangles are equal.

[tex]\rm \dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{AC}{XZ}[/tex]

Step 4 - Now, substitute the values of YZ, XY, and AB in the above expression.

[tex]\rm \dfrac{15}{5}=\dfrac{BC}{12}[/tex]

Step 5 - Simplify the above expression.

BC = 36

Answer:45°

Step-by-step explanation:

First we need to find x

(5x-5)+(3x+3)+(5x)=180

Simplify

13x-2=180

Add 2 to each side

13x=182

Divide each side by 13

x=14

Now apply our x to angle B

Answer:

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Step-by-step explanation:

you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain

Dough = 6 ounces

Suase = 4 ounces

Dough + sauce = 6 + 4 = 10

Let x = total number of guests

Dough ingredients + sauce ingredients = 130

10x = 130

Divide both sides by 10

x = 130/10

= 13

x = 13

Number of guests = 13

Total ounces of dough = 6 ounces × 13 guests

= 78 ounces of dough

Total ounces of sauce = 4 ounces × 13 guests

= 52 ounces of sauce

Therefore,

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Answer:

b = 40

Step-by-step explanation:

The first step you have to do is multiply 4 on each side to cancel out the 4 under -b, so you can get b by itself.

4 x -10 = -b  x 4        should get this       -40 = -b

              4

Now the final step is to divide -1 on each side to cancel out the negative by b, thus getting b by itself. Then once that is done you will see that your answer is b=40.  

-40 = -b         should get this     40=b or b=40

-1      -1

Answer:

Total amount taken in by the depeloper from the sale of apps = sum(5.99 * x * P(x))

= 5.99*0*0.05 + 5.99*20*0.25 + 5.99*40*0.18 + 5.99*60*0.12 + 5.99*80*0.3 + 5.99*100*0.1

= 319.87

Ans: $319.87

Step-by-step explanation:

The expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.

The continuous uniform distribution, sometimes known as the rectangle distribution, is a family of symmetric probability distributions in probability theory and statistics.

We have:

The number of apps a developer sells daily has the probability distribution represented in the table:

Number of Apps, x       0      20    40     60      80    100

P(x)                              0.05  0.25  0.18   0.12     0.3     0.1

Each app sells for $5.99

We can calculate the expected daily total dollar amount taken in by the developer from the sale of apps:

The total amount is taken in by the developer from the sale of apps:

= sum(5.99x[P(x)])

= 5.99×0×0.05 + 5.99×20×0.25 + 5.99×40×0.18 + 5.99×60×0.12 +

   5.99×80×0.3 + 5.99×100×0.1

= 0 + 29.95 + 43.128 + 43.128 + 143.76 + 59.9

= 319.866 ≈ $319.87

Thus, the expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.

Answer:

You will get there in 4 hours

Step-by-step explanation:

Use the distance formula D=r•t , to determine how much time, t, in hours it will take you to get there

Where D = Distance

r = rate = Average Speed

t = time in hours

From the question

D = 220 miles

t = ??

r = 55 miles/hour

Hence:

220miles = 55miles/hour × t

t = 220/55

t = 4 hours

You will get there in 4 hours

Step-by-step explanation:

Coordinate Plane

The image provided shows the four points given:

A=(2, 1), B=(5, 1), C=(7,2), D=(4,2).

It can be clearly seen the length of CD is just the difference of their x-coordinates:

CD = 7 - 4 = 3

We can also use the formula of the distance.

Given two points C(x,y) and D(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

[tex]d=\sqrt{(2-2)^2+(7-4)^2}[/tex]

[tex]d=\sqrt{0^2+3^2}[/tex]
