Answer: 238

Step-by-step explanation:

The formula to calculate the nth term of an arithmetic progression = a + (n-1)d

Based on the question,

a = -140

90th term = a + 89d = 483

We need to get the value of the common difference

a + 89d = 483

-140 + 89d = 483

89d = 483 + 140

89d = 623

d = 623/89

d = 7

Therefore 55term will be:

= a + (n - 1)d

= a + (55 - 1)d

= a + 54d

= -140 + 54(7)

= -140 + 378

= 238

Answer:

Approximately 2 weeks

Step-by-step explanation:

Given data

Cost of bike=  £250

Assuming she works for 6 days

1.Babysitting

6*2.75=£16.5 per day

for 6 days

=16.5*6

=£99

2. Saturday Job

=£27.50

Total earnings for the week

=£27.50+£99

=£126.5 weekly

Hence it will take her

=250/126.5

=1.97 week

Approximately 2 weeks to save up the amount

From weakest to strongest values:

-0.78, -0.15, 0.35, 0., 67

Weakest to strongest data sets:

K, M, J, L

Answer:

A

Step-by-step explanation:

You need a value that keeps 79% of the previous value. 79% is 0.79 as a decimal.

You get that by taking 100% of the value and subtracting 21% of the value. Said easier (100% x - 21%x = 79% of x.

r = 0.79

Answer:

B

Step-by-step explanation:

To find the y- intercept let x = 0

From the table for f(x)

When x = 0 → f(x) = - 4

That is the y- intercept = - 4

Given

g(x) = 3 [tex](2)^{x}[/tex]

let x = 0 , then

g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]

       = 3 × 1

       = 3

That is the y- intercept = 3

Thus the y- intercept of g(x) is greater → B

445.4

Step-by-step explanation:

Well to find the volume of a rectangular prism, the formula is l x w x h (length x width x height). The length is 3.4, the width is 10, and the height is 13.1. If you multiply all three of those numbers, you get 445.4.

Answer:

1.25 hours

Step-by-step explanation:

Benjamin rode tghe train for 45 minutes. Then it took him another 30 minutes to walk to his friend's house. How many hours did he spend riding and walking to his friend's house?

The number of hours he spent riding and walking to his friends house is calculated as:

45 minutes + 30 minutes

= 75 minutes

Converting this to hours

60 minutes = 1 hour

75 minutes = x

Cross Multiply

60 × x = 75 × 1

x = 75/60

x = 1.25 hours

Answer:

2x + 7 > 25 ; 9

Step-by-step explanation:

Total worth of Jacob's cards = $25

Number of Bonita's card = x

Worth of Bonita's card = $2 each

Worth of Madison card = $7

Bonita and Madison cards are worth more than Jacob's card

The inequality

Bonita = 2x ; Madison = 7

2x + 7 > 25

Solving for x

2x > 25 - 7

2x > 18

x > 18 /2

x > 9

Answer:

Option 3

Step-by-step explanation:

The sentence provides the reasoning for a possible explanation.

Now, let's look at all the possible answers:

1. This doesn't show us that scientists cannot agree. A sentence like that could be that many scientists have analyzed the region, but they did not find anything.

2. This does not tell us that this region is interesting. A sentence like that would be saying that the cause of the lightning is unknown.

3. This is correct- it provides evidence for a main theory.

4. This does not explain why people name the lightning a certain way. A sentence like that could be a local fable.

Answer:

y = (x + 1)(x - 0.586) ( x - 3.414)

Step-by-step explanation:

I sure wouldn't recommend doing this by trial and error.

I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.

y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2

are the listed roots.

The square root is

y = (x + 1)(x - 0.586) ( x - 3.414)

Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2

you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Answer:

-23

Step-by-step explanation:

Given 4v-3

evaluate when v = -5

So basically we want to find the value of the expression when the variable (v) equals -5

so

* plug in -5 for v*

4(-5)-3

4*-5=-20

-20-3=-23

So we can conclude that when v = -5 the value of the expression is -23

Answer:

Explanation:

given the expression: 4v-3

if  v = -5

4v-3 (let's subsitute v)

4v-3 = 4×(-5)-3

4v-3 = -20 - 3

4v-3 = -23

Step-by-step explanation:

or,(x-2)(x-4)+(3x-11)(x-3)/(x-3)(x-4)=(4x+13)/(x+1)

or,x^2-4x-2x+8+3x^2-9x-11x+33/x^2-4x-3x+12=(4x+13)/(x+1)

or,4x^2-4x-2x-9x-11x+8+33/x^2-7x+12=(4x+13)/(x+1)

or,4x^2-26x+41/x^2-7x+12=(4x+13)/(x+1)

or, (x+1)(4x^2-26x+41)=(4x+13)(x^2-7x+12)

or,4x^3-26x^2+41x+4x^2-26x+41=4x^3-28x^2+48x+13x^2-91x+156

or,-26x^2+4x^2+28x^2-13x^2+41x-26x-48x+91x=156-41

Either, Or,
