student purchased 7 binders for a total of $8.61. Write an equation that can be used to find the cost of each binder, n, in dollars. What is the cost, in dollars,
Of each binder?

Answer:

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

Step-by-step explanation:

The shape of that function is exponencial.

All expoencial functtion passed though the point (0,1).

In that case we have the point (4,16) in other words: (4,2⁴)

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

Answer:

4 seconds

Step-by-step explanation:

[tex]\frac{30,000}{1} =\frac{2,000}x}[/tex]

The numerator is the distance and the denominator is the time.

I used cross multiplication, the numerator of one fraction times the denominator of the other.

[tex]30,000*x=2,000*1\\30,000x=2,000[/tex]

divide both sides by 30,000 and simplify

[tex]x=\frac{2,000}{30,000} \\x=\frac{2}{30}[/tex]

Then multiply the fractions by 2/2 (basically multiplying the numerator and the denominator each by 2)

[tex]x=\frac{4}{60}[/tex]

Since the denominator is 60, the number of seconds in a minute, the numerator is the answer

I hope this makes sense ;-;

Answer

12. x = 15, y = 21

13. x = 10, M = 37, N = 84, P =59

14. x = 19, R = 43, S = 20, T = 117

15. A = 21, B = 125, C = 34

16. J = 48, K = 57, L = 75

Explanation

12. 6x - 11 + x + 5 + 81 = 180

     7x + 75 = 180

     7x = 105

     x = 15

     4y - 18 + y + 14 + 6*15 - 11 = 180

     5y + 75 = 180

     5y = 105

     y = 21

13. 4x - 3 + 9x - 6 + 6x - 1 = 180

    19x - 10 = 180

    19x = 190

    x = 10

    M = 4*10 - 3 = 37

    N = 9*10 - 6 = 84

    P = 6*10 - 1 = 59

14. R = 2x + 5

    S = x + 1

    T = 7x - 16

    2x + 5 + x + 1 + 7x - 16 = 180

    10x - 10 = 180

    10x = 190

    x = 19

   R = 2*19 + 5 = 43

   S = 19 + 1 = 20

   T = 7*19 -16

15. A = C -13

    B = 4C - 11

    c - 13 + 4c - 11 + c = 180

    6c -24 = 180

    6c = 2-4

    C = 34

   A = 34 - 13 = 21

   B = 4*34 - 11 = 125

16. K = J + 9

     L = 2J -21

     j + 9 + 2j - 21 + j = 180

    4j -12 = 180

    4j = 192

    J = 48

    K = 48 + 9 = 57

    L = 2*48 -21 = 75

Answer:

£280.0

Step-by-step explanation:

Given the following

Rate R= 4%

Time T = 1year

Amount = £291.20

Simple Interest I = ?

I = PRT/100

A = P+I

Since P = A-I

I = (A-I)RT/100

I = (291.2-I)RT/100

100I = (291.2-I)4

100I = 1,164.8-4I

104I = 1,164.8

I = 1,164.8/104

I =  £11.2

Amount = P+I

Principal = A-I

P = 291.2-11.2

P = 280.0

Hence patrick invested £280.0

The volume of the cone will be 2120 cm³, i.e. option B.

Volume is the amount of space that something contains or fills.

volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]

We have,

Height = 9 cm,

Radius = 15 cm

So,

volume of the cone [tex]=\frac{1}{3} \pi r^{2} h[/tex]                

i.e.

volume of the cone [tex]=\frac{1}{3} * 3.14 * 15^{2} * 9[/tex]

On solving we get,

Volume of the cone = 2119.5 = 2120 cm³

Hence, we can say that the volume of the cone will be 2120 cm³, i.e. option B.

Step-by-step explanation:

[tex]24 = x^2 - 4x + 3\\\\ x^2 - 4x + 3-24=0\\\\\underbrace{x^2-2\cdot x\cdot2+2^2}-2^2-21=0\\\\{}\qquad(x-2)^2-25=0\\\\{}\qquad\bold{(x-2)^2=25}\\\\{}\qquad x-2=\pm\sqrt{25}\\\\{}\qquad \bold{x=2\pm5}[/tex]

the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5

The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.

part 1
Given equation,
x² - 4x + 3 = 24
x² - 4x + 4 - 4 + 3 = 24
(x - 2)² - 1 = 24
(x - 2)² = 24 + 1
(x - 2)² = 25

Part 2

Solution for the given equation that transformed in part 1 of the solution.
(x - 2)² = 25
(x - 2) = √25
(x - 2) = ±5
x = 2 ± 5

Thus , the required equation for 1 is (x - 2)² = 25 and solution for 2 is x = 2 ± 5

Answer:

5

Step-by-step explanation:

For these types of problems, we can use cross - multiplication.

4/32 = x/40

Notice that since 40 and 32 are both measured in minutes, we put them on the same line.

Now, like the name suggests, we cross multiply the equation, by doing 4 * 40 = 32 * x. Now, we are left with 160 = 32x. After solving this, we get the answer 5.

Answer:

b. Non-proportional

Step-by-step explanation:

A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.

The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:

y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4

Therefore, it is non-proportional.

Answer:

10 times.

Step-by-step explanation:

He rolls all the dice independently, so The expected number of 3's is 60 * (expected number of 3's in one throw).

The expected number of 3's in one throw is:

5/6 * 0 + 1/6 * 1 = 1/6

because 5/6 of the time we roll zero 3's and 1/6 of the time we roll one 3 :D

So he should expect (60 * 1/6 = 10) 3's in 60 throws.
