Explanation:

If we multiply 10x8 we would get 80. If 78 people show up, we would subtract 78 from 80 and our answer would be two.

Answer:

[tex]a_7=40960x^{33}[/tex]

Step-by-step explanation:

Geometric sequence has explicit form:

[tex]a_n=a \cdot r^{n-1}[/tex] where [tex]a[/tex] is first term and [tex]r[/tex] is the common ratio.

First term here is [tex]a=10x^3[/tex] and [tex]r[/tex] could be found by doing second term divided by first term, [tex]\frac{40x^8}{10x^3}=4x^5[/tex].

Therefore the [tex]n[/tex]th term is given by

[tex]a_n=10x^3 \cdot (4x^5)^{n-1}[/tex].

So the [tex]7[/tex]th term is given by

[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex].

Let's simplify:

[tex]a_7=10x^3 \cdot (4x^5)^{7-1}[/tex]

[tex]a_7=10x^3 \cdot (4x^5)^{6}[/tex]

[tex]a_7=10x^3 \cdot (4^6(x^5)^6)[/tex]

[tex]a_7=10x^3 \cdot (4096x^30)[/tex]

[tex]a_7=40960x^{33}[/tex]

Answer:

BOC = 42

Step-by-step explanation:

90 = 6z - 6 + 5z + 8

Combine common factors

90 = 11x + 2

Subtract 2 from both sides

88 = 11x

Divide both sides by 11

8 = x

Plug in 8 for x

6(8)- 6

48 - 6

42

Answer:

7000

Step-by-step explanation:

This is because when you round to the significant figure, you basically look at any digits at the start of the number, which isn't zero. In this case, it would be in the thousands place 7284. So you round 7284 to the nearest thousands, which, would be 7000

Step-by-step explanation:

let the price of fruits be X per kg

cp of 50kg of friuts =50x

he sells 30kg of fruits on its cp of 35 kg

cp of 30kg fruits=30x

sp of 30kg fruits=35x

remaing fruits is 20kg

he sells 20kg of fruits on cp of 16kg

cp of 20kg fruits=20x

sp of 20kg fruits =16x

total cp is =50x

total sp is =(35+16) =51x

sp>cp(it means profit)

profit =sp-cp

=51-50

= 1

profit%=gain/cp × 100

= 1/50×100

=2%

Answer:

19, 25, 32

Step-by-step explanation:

Find the difference within each number:

5 -> 7: + 2

7 -> 10: + 3

10 -> 14: + 4

With each difference, + 1 is added so we can infer the next difference will be + 5.

14 + 5 = 19

Next is + 6.

19 + 6 = 25

Now + 7.

25 + 7 = 32

f: M ⇒ N is a function from M to N.

Given,

f: M ⇒ N

We need to describe this mathematical statement in our own words.

A function is defined as a way where there is an input that it takes and produces an output.

The set from where the inputs come is called the Domain.

The set of outputs is called the Range.

We have,

f: M ⇒ N

Here

f is a function that takes input from the set M and its output belongs to set N( Natural number).

Here,

M is called the domain.

N is called the codomain.

Thus f: M ⇒ N is a function from M to N.

Step-by-step explanation:

number of shirts = x

price of shirts made = 9x+20

amount u earn by selling the shirts = 15x

profit = 15x - (9x+20)

profit of at least 150,

Answer:

  432 ft²

Step-by-step explanation:

The radius is half the diameter.

  r = (24 ft)/2 = 12 ft

Put the given numbers into the formula and do the arithmetic.

  A = πr²

  A = (3)(12 ft)² = 432 ft²

Answer: London and Moscow.

Step-by-step explanation: This problem is simple. First, we use process-of-elimination. None of the positive values have a difference of 25 degrees, so one of the two values must be -12 degrees aka Moscow. From there, we add 25 to -12 to get 13. This means that the other city is London since it is 13 degrees.

Answer:

(4^3)5 = 4^15

Step-by-step explanation:

The expression [tex](x^2 + 1)(y^2 + 4)[/tex] can be rewritten using Two Squares as [tex](xy-2)^2+(x+2y)^2[/tex]. The correct option is D.

The Two Squares identity is a special case of the identity: [tex](a^2 + b^2) = (a + b)^2 - 2ab[/tex].

This identity can be used to factorize certain expressions involving squares of variables.

By using the Two Squares identity, we can rewrite expressions in the form of a sum of two squares as a difference of squares, or vice versa. This can be useful in simplifying and solving equations in algebra.

We can use the Two Squares identity, which states that:

[tex](a^2 + b^2)(c^2 + d^2) = (ac - bd)^2 + (ad + bc)^2[/tex]

Comparing with the given expression, we can see that a = x, b = 1, c = y, and d = 2. Substituting these values into the Two Squares identity, we get:

[tex](x^2 + 1)(y^2 + 4) = (xy - 2)^2 + (x + 2y)^2[/tex]

Therefore, the answer is (D) [tex](xy-2)^2 + (x+2y)^2.[/tex]

Answer: Um

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let x = the hourly rate of the first mechanic and

     y = the hourly rate of the second mechanic.

As far as the equation goes for the total amount charged:

10x + 5y = 950

As far as the equation goes for the sum of the 2 mechanics' rates:

x + y = 125

Solve the first equation for either x or y. I solved for y:

y = 125 - x

Now plug that into the first equation for y to get:

10x + 5(125 - x) = 950 and

10x + 625 - 5x = 950 and

5x = 325 so

x = 65

The first mechanic charges $65 per hour and the second mechanic charges

y = 125 - 65 so

the second mechanic charges $60 per hour.

Answer:

5^5

Step-by-step explanation:

5^3 * 25

Note that 25 = 5^2 (which is 5 * 5)

so we can rewrite the first expression as

5^3 * 5^2

We can add the exponents because we are multiplying and there is the same base (5):

5^(3+2) = 5^5
