Answer:

-9

Step-by-step explanation:

Given :-

And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.

Sequence :-

[tex]:\implies[/tex] -5 , -14 , -23

Common difference :-

[tex]:\implies[/tex] CD = -14 -(-5) = -14+5=-9

[tex]:\implies[/tex] CD = -23-(-14) = -23+14=-9

Hence the common difference is (-9) .

For given question,

Charlotte the turtle was born with 4 squares on her shell, as in the first picture below.

When she was 1 year old, 12 new squares appeared around the old squares, as in the second picture below.

Each year, a new group of squares appeared around the old squares.

We find the same pattern to find the new squares appeared when she is 2 and 3 years old.

When she is 2 years old then the new squares appeared around the old squares, as shown below.

There are 20 new squares appeared around the old squares.

When she is 3 years old then the new squares appeared around the old squares, as shown below.

There are 28 new squares appeared around the old squares.

Therefore, when age is 2 then the new squares appeared = 20

when age is 3 then the new squares appeared = 28

Answer:

12.0 meters

Step-by-step explanation:

Given data

The first is 8.75 meters long

Let us find 37.5% of  8.75

=37.5/100*8.75

=0.375*8.75

=3.28125

Hence the Second seawall is

=3.28125+8.75

Answer:

B. 2s + 100 when s=80 the latest balance of Ahmed’s savings is $260

Step-by-step explanation:

We are given that the savings = $s and current amount  $c.

Now, Ahmed has doubled his savings. This means that the new savings = $2s

Also, he had deposited $100.

So, the current amount of Ahmed is given by c = 2s + 100.

Moreover, if the savings is $80 i.e. s = 80, the current amount is,

c = 2 × 80 + 100

i.e. c = 160 + 100

i.e. c = 260

So, the current amount if savings is $80 is $260.

Hence, the expression for current amount is 2s + 100 and if s = 80, the current amount is $260.

The mean is 8 and the lower quartile is 6.

We will see that the percentage of the 60 children who choose orange is 25%.

In this case, the 60 children are the 100%.

We want to find which percentage 15 (number of kids that like orange) represents.

Then we can write:

15 = x

60 = 100%

x = (15/60)*100% = 25%

So we conclude that 25% of the children choose orange.

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.

The volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

The volume of the cuboid is the space occupied by the 3D object cuboid. It is the product of the length, width, and depth of the cuboid.

As it is given that we need to make a rectangular foundation, therefore, the shape of the foundation will be a cuboid with sides 5 feet wide, 17 feet long, and depth of 6 inches.

Now, as we know large amounts of concrete can be purchased by the cubic yard only, therefore, we will convert each of the sides of the rectangular foundation into yards.

[tex]\rm Wide, w = 5\ feet = 5 \times \dfrac{1}{3} = \dfrac{5}{3}\ yards\\\\Length, L = 17 feet = 17 \times \dfrac{1}{3} = \dfrac{17}{3}\ yards\\\\Depth, D = 6\ inches = 0.5\ feet = 0.5 \times \dfrac{1}{3} = \dfrac{0.5}{3}\ yards\\\\[/tex]

Now, we know that the volume of the cuboid is given as the product of its length, width, and depth. therefore,

[tex]\text{Volume of Cuboid} = Length\times Width\times Depth[/tex]

                             [tex]= \dfrac{5}{3} \times \dfrac{17}{3} \times \dfrac{0.5}{3}\\\\= \dfrac{42.5}{27}\\\\=1.574\rm\ yards^3[/tex]

Hence, the volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

Answer:

6.16 hours

Step-by-step explanation:

Let the number of hours that washed the car together = T

Number of hours Matthew washed = m = 14 hours

Number of hours Arianna washed = a = 11 hours

The formula to calculate how many they wash the cars together is given as

1/a + 1/m = 1/T

1/14 + 1/11 = 1/T

Lowest Common Denominator = 154

Hence:

(11 + 14)/154 = 1/T

25/154 = 1/T

Cross Multiply

154 × 1 = 25 × T

T = 154/25

T = 6.16 hours

Therefore, it will take Matthew and Arianna 6.16 hours to wash the cars together

Answer:

below

Step-by-step explanation:

A)1 can be interpreted as the job, the project, the whole thing or all of the cars

B)rate* time = amount of work (a bit like rate*time = distance for figuring how far you go at a certain speed)

C)multiply both sides by 14 hours/1 job and simplify to get t=14hours

D) ok, now we do the 2nd fraction 1/11 we want its bottom to be 154, like: 1/14 - 11/11

E)t=154/25=t= 6.16 hours

Select the correct answer from each drop-down menu.

We solve using z score formula

z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.

a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.

z = 45 - 70/25

b) The probability of a randomly selected student completing the test in 95 minutes is %.

To divide by (x+1) in synthetic division, you divide by -1.

-1    1   -7   4   12

         -1    8   -12

—————————-

     1   -8   12   0

This gives us x^2 -8x +12x  which factors to (x-2) (x-6).  We still have the factor of (x+1)  so the zeros will be 2, 6, and -1.

Answer:

2 AND -10

Step-by-step explanation:

Answer:

domain: all real numbers except 2 and -10; x-intercept: 4; y-intercept:  1/5

Step-by-step explanation:

The domain consists of the set of all possible values x can be. In a fraction, the denominator cannot be equal to 0. We can solve for the values x cannot be equal to by factoring and exclude them out of the domain once we’ve found them:

To factor x^2 + 8x - 20, we are looking for two numbers that have a product of -20 and a sum of 8. These two numbers are 10 and -2. So, it can be factored to:

(x + 10)(x -2) not equal 0

So x ≠ 2 and x ≠ -10.

To find the x-intercept, the value of y would be zero. We can substitute y as 0 to get:

0 = (x - 4) / x^2 + 8x - 20

The only way for this fraction to equal 0, is for the numerator to be 0. We get the equation:

x - 4 = 0,

And x = 4

To find the y-intercept, the value of x would be 0. We can substitute x with 0 to get:

y = -4 / -20 = 1/5

These answers align with the second option.
