The combined cost for 1 pound of turkey and 1 pound of ham is $10.5

Step-by-step explanation:

Let,

Turkey = x

Ham = y

According to given statement;

4x+2y=30    Eqn 1

x = y-1.50     Eqn 2

Putting value of x from Eqn 2 in Eqn 1

[tex]4(y-1.50)+2y=30\\4y-6+2y=30\\6y=30+6\\6y=36[/tex]

Dividing both sides by 6

[tex]\frac{6y}{6}=\frac{36}{6}\\y=6[/tex]

Putting y=6 in Eqn 2

[tex]x=6-1.50\\x=4.5[/tex]

1 turkey costs $4.5 and 1 ham costs $6.

Combined cost of 1 pound of turkey and ham each = 4.5+6=$10.5

The combined cost for 1 pound of turkey and 1 pound of ham is $10.5

Answer:

The weekly savings of first person = $900

The weekly savings of second person = $700.

Step-by-step explanation:

Let us assume the income of first person = $ m

Now, as the difference in the income is $200.

⇒ And the income of first person  -  income of first person =  $200

⇒ Income of second person    =    m -  $200

So, according to the question:

Ratio of   Income of First person : Second Person's Income  =  9: 7

or, m : ( m - 200)   =  9: 7  

[tex]\implies  \frac{m}{m - 200 }  = \frac{9}{7}[/tex]

[tex]7 \times m = (m - 200) \times 9\\\implies 7 m = 9m - 1800\\\implies 7m - 9m = -1800\\\implies -2m = -1800\\m = \frac{1800}{2}   = 900[/tex]

or,m = $900

Hence, the weekly savings of first person = $900

and the weekly savings of second person = m - 200 = $900 - 200 = $700.

Final answer:

To find the weekly incomes of two persons with a ratio of 9:7 and a difference of $200, represent their incomes as 9x and 7x. Solving for x, we get $100, so their incomes are $900 and $700 respectively.

Explanation:

The question asks us to solve for the weekly incomes of two persons given that the ratio of their incomes is 9:7 and the difference between their incomes is $200.

Let's represent the incomes of the two persons as 9x and 7x respectively, where x is a common multiplier. According to the information provided,

9x - 7x = $200

Solving for x:

(9x - 7x) = 2x

2x = $200

x = $200 / 2

x = $100

Now calculating each person's income:

Person A: 9x = 9 * $100 = $900

Person B: 7x = 7 * $100 = $700

Therefore, the weekly incomes of the two persons are $900 and $700 respectively.

Final answer:

The two numbers that have a sum of 126 and a difference of 42 are 84 and 42.

Explanation:

To find the two numbers whose sum is 126 and whose difference is 42, we can set up a system of equations:

x + y = 126 (Sum of the numbers)

x - y = 42 (Difference of the numbers)

By adding these two equations, we can eliminate y and solve for x:

x + y + x - y = 126 + 42

2x = 168

x = 84

Now that we have the value of x, we can find y by substituting x back into either of the equations. For example:

84 + y = 126

y = 126 - 84

y = 42

Therefore, the two numbers are 84 and 42.

Answer:

Step-by-step explanation:

Since the 2 lines are parallel, then

d = 55° ( corresponding angles are congruent )

e = 55° (vertical to d and congruent )

e and f are same side interior angles and are supplementary, thus

e + f = 180°, that is

55° + f = 180° ( subtract 55° from both sides )

f = 125°

c = 125° ( alternate to f and congruent )

Hence

c = 125°, d = 55°, e = 55°, f = 125°

Carter had his songs played in 7 commercials and 5 movies to earn $1000 in royalties. This was determined by solving a system of linear equations.

Carter is dealing with a system of linear equations situation where he collects different amounts of royalties based on whether his music is played in commercials or movies. We can represent the number of commercials as c and the number of movies as m. Since he earns $50 per commercial, we can write the first equation as 50c, and since he earns $130 per movie, we can write the second equation as 130m. Carter earned a total of $1000 from 12 commercials and movies, which gives us two equations:

50c + 130m = 1000

c + m = 12

By solving this system of equations, we can determine the number of commercials and movies. Multiplying the second equation by 50 gives us 50c + 50m = 600, which we can subtract from the first equation to eliminate c and solve for m. Doing so, we get:

50c + 130m = 1000

-(50c + 50m = 600)

After subtracting, we are left with 80m = 400, from which we can solve for m to find that m = 5. Using the second original equation, we can now find out that c = 7.

So, Carter had his songs played in 7 commercials and 5 movies to earn a total of $1000 in royalties.

The lengths of the sides are 24cm, 27cm and 30cm.

Therefore,

The length of sides is 8x, 9x and 10x.

Perimeter is the sum of 3 sides, therefore,

The lengths of the sides of the triangle are 24 cm, 27 cm, and 30 cm.

To find the lengths of the sides of the triangle, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter. Let's assume the common ratio between the sides is 'x'. So, the lengths of the sides can be written as 8x, 9x, and 10x. According to the problem, the perimeter of the triangle is 81 cm.

Therefore, 8x + 9x + 10x = 81.

Combining like terms, we get 27x = 81.

Dividing both sides by 27, we find that x = 3.

Substituting this value back into the lengths of the sides, we find that the lengths are 8x = 8(3) = 24 cm, 9x = 9(3) = 27 cm, and 10x = 10(3) = 30 cm.

Here, [tex](4)^{2}  + (8)^{2}   = 16 + 64  = 80\\\implies H = \sqrt{80}  =  8.94[/tex]

So, third side of the triangle   8.94 ≠ 12

Hence,  {4, 8, 12} is NOT a triplet.

(b) {6, 8, 10}

Here, [tex](6)^{2}  + (8)^{2}   = 36 + 64  = 100\\\implies H = \sqrt{100}  =  10[/tex]

So, third side of the triangle  10

Hence,  {6, 8, 10} is  a triplet.

(c) {6, 8, 15}

Here, [tex](6)^{2}  + (8)^{2}   = 36 + 64  = 100\\\implies H = \sqrt{100}  =  10[/tex]

So, third side of the triangle  10  ≠ 15

Hence,  {6, 8, 15} is  NOT a triplet.

(d) {5, 7, 13}

Here, [tex](5)^{2}  + (7)^{2}   = 25 + 49  = 74\\\implies H = \sqrt{74}  =  8.60[/tex]

So, third side of the triangle  8.60  ≠ 13

Hence, {5, 7, 13} is  NOT a triplet.

Answer:

The population will be 240,116

Step-by-step explanation:

Exponential growth can be represented by the expression:

[tex]P(t) = P_i\,(1+r)^t[/tex]

where:

[tex]P(t)[/tex] is the population at time (t)

[tex]P_i[/tex] is the initial value of the population

"r" is the annual rate of growth (written in decimal form)

and "t" is the time in years.

Therefore in this situation, P(16) is what we want to find [the population after 16 years]

the initial population [tex]P_i[/tex] is 110,000

the rate of growth is 0.05 [decimal form of 5%]

and t is 16 years.

Replacing all these in the given functional form gives:

[tex]P(t) = P_i\,(1+r)^t\\P(16)=110000\,(1+0.05)^16\\P(16)=240116[/tex]

An exponential function to model a population of 110,000 that grows at 5% per year for 16 years is P(t) = 110,000 ∙ (1.05)^t. After 16 years, using this exponential function, the population would be approximately 242,884.

To model the population growth using an exponential function, we can use the formula P(t) = P0 ∙ (1 + r)t, where P(t) is the population after t years, P0 is the initial population, r is the growth rate, and t is the time in years. In this case, the initial population P0 is 110,000, the growth rate r is 5% (or 0.05), and the time t is 16 years.

The exponential growth function would be:

P(16) = 110,000 ∙ (1 + 0.05)16

To find the projected population after 16 years, we'll calculate:

P(16) = 110,000 ∙ (1.05)16
P(16) = 110,000 ∙ 2.20804
P(16) = 242,884.4

After rounding, the population would be approximately 242,884 after 16 years.

Answer:

90°, 60°, and 30°

60°.

Step-by-step explanation:

The triangle ABC has side lengths √6, √2, and 2√2 units.

It is clear that the triangle ABC is right triangle because (2√2)² = (√6)² + (√2)² that means the side lengths satisfy the Pythagoras Theorem.

Now, if the angle between hypotenuse (2√2 units) and base (√2 units) is [tex]\theta[/tex], then

[tex]\cos \theta = \frac{\sqrt{2} }{2\sqrt{2} }  = \frac{1}{2}[/tex]

Hence, [tex]\theta[/tex] = 60°

Therefore, the three angles of the triangle are 90°, 60°, and 30°.

Now, if the base of the triangle is 16 units, then other two side lengths will also change proportionally to remain the triangle a right triangle.

And in that case the base angle will remain 60°. (Answer)
