Answer:

Nick get = $10

Pam get = $28.25

Step-by-step explanation:

Given:

Total amount paid = $38.25

Nick work = 1 hour 5 minutes = 1.0833 hr

Pam work = 3 hour

Find:

Amount they get

Computation:

Assume each get x in 1 hour

So,

3x + 1.0833x = 38.25

4.0833x = 38.25

x = 9.3674

Nick get = 1.0833(9.3674) = 10.14 = $10

Pam get = $38.25 - $10 = $28.25

The equation for break even is 8P = 48

An equation is an expression that states the equality of two things expressed in different form.

In the given question

Conard spent $48 for art supplies

Canvas costs $2

He plans to sell his painting for $10

∴ Without the canvas his paintings costs $(10 - 2)

= $8

So, no. of paintings (P) to break even he needs to sell

8P = 48

P = 6

∴ Conard needs to sell 6 paintings to break even.

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks [tex]=2\times 3=6[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-6[/tex]

                                     [tex]=44[/tex]

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks [tex]=2\times x=2x[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-2x[/tex]

So, Mia's test score is (50-2x) if she got x questions wrong.

Answer:

x = 7.5

Step-by-step explanation:

Step 1: Subtract x from both sides.

1.5x−0.5−x=x+3.25−x

0.5x−0.5=3.25

Step 2: Add 0.5 to both sides.

0.5x−0.5+0.5=3.25+0.5

0.5x=3.75

Step 3: Divide both sides by 0.5

0.5x ÷ 0.5 = 3.75 ÷ 0.5

Answer:

x=3

Step-by-step explanation:

2/3x -4 = -2

2/3x = 2

(3/2)*(2/3x) = (2*3/2)

x=3

Answer:

x=3 I hate asking for things but may  i have brainliest I need to rank up

Step-by-step explanation:

Step 1: Add 4 to both sides.

2/3x−4+4=−2+4

2/3x=2

Step 2: Multiply both sides by 3/2.

(3/2)*(2/3x)=(3/2)*(2)

then you get x=3

Answer:

3.

Step-by-step explanation:

1/x = (x+3)/(2x^2), where x ≠ 0.

Cross-multiply to give 2x^2 = x(x+3).

2x^2 - x^2 - 3x = 0

x^2 - 3x = 0

x(x - 3) = 0

x = 3 or x = 0 (rejected because equation will be undefined)

Step-by-step explanation:

Answer:

y(t) = 494 (1.03)^t

y(10) = 663,89

Step-by-step explanation:

An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year

This increase in population continues for t years

Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is

y(t) = 494 (1.03)^t

Where,

y = population

t = number of years

Find y when t = 10

y(t) = 494 (1.03)^t

y(10) = 494 (1.03)^10

= 494 ( 1.3439)

= 663.8866

Approximately y(10) = 663.89

This means that after 10 years from when the population was 494,000, it increased to 663,89.

5.3× 10⁴= ?

Step-by-step explanation:

10⁴ can also be written as 10×10×10×10= 10000

so, 5.3 × 10000= 53000

Scientific notations are the way through which a very small or a very large number can be written in shorthand. The value of 5.3×10⁴ in standard form is equal to 53,000.

Scientific notations is the way through which a very small or a very large number can be written in shorthand.  In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

Given the numerical value 5.3×10⁴ which is needed to be written in the standard form, therefore, we can write,

5.3 × 10⁴

= 5.3 × 10,000

= 53,000

Hence, the value of 5.3×10⁴ in standard form is equal to 53,000.

[tex]\mathtt{\Delta K.E = 10500 \ J}[/tex]

Step-by-step explanation:

Given that:

the expression for the change in kinetic energy = [tex]\dfrac{1}{2} \times 350 \times ( 122 -62)[/tex]

Recall that

Kinetic energy K.E = [tex]\dfrac{1}{2}mv^2[/tex]

where,

m = mass of the horse

v = velocity of the horse

The change in kinetic energy between  two instant times can be expressed by the relation

[tex]\Delta K.E = K.E_2 - K.E_1[/tex]

[tex]\Delta K.E =\dfrac{1}{2}mv^2_2- \dfrac{1}{2}mv^2_1[/tex]

[tex]\Delta K.E =\dfrac{1}{2}m(v^2_2-v^2_1)[/tex]

where;

m = 350

[tex]v_2[/tex] = 122

[tex]v_1[/tex]= 62

[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (122-62)[/tex]

[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (60)[/tex]

[tex]\Delta K.E = 350 \times 30[/tex]
