george buys a bowl of soup and bread for $8.00 and leaves a 6% tip what is the total cost of the meal

Answer:

The price of a drink = $4

The price of a bag of popcorn = $5.5

Step-by-step explanation:

Let p represent popcorn and d represent drink

Harper bought 10 bags of popcorn and 6 drinks and paid $79 ➡ 10p + 6d = $79

Damian bought 3 bags of popcorn and 5 drinks and paid $36.50 ➡ 3p + 5d = $36.50

Now multiply first equation by -3 and second equation by 10

-3 × (10p + 6d) = $79 ➡ -30p - 18d = -$237

10 × (3p + 5d) = $36.50 ➡ 30p + 50d = $365

Now add the new equationd

30p + 50d -30p - 18d = $365 - $237 (-30p will eliminate 30p)

32d = $128 divide both sides of the equation by 32

32 ÷ 32d = 32 ÷ $128 ➡ d = 4

If d = 4 that means a drink costs $4 we can use this information to find the price of a bag of popcorn

3p + 5d = $36.50 (replace d with 4)

3p + 4×5 = $36.50

3p + 20 = $36.50

3p = $36.50 - 20

3p = 16.50 divide both sides by 3

p = $5.5

The question asked to set up a system of equations to determine the price of each bag of popcorn and each drink. Using the variables x and y to represent the price of popcorn and drinks respectively, the system of equations based on the information given is 10x + 6y = $79 and 3x + 5y = $36.50.

To solve this problem, we need to setup a series of equations based on the information given. Let's say:

According to the first scenario with Harper, we get:

10x + 6y = $79

From Damian's shopping, we have:

3x + 5y = $36.50

This gives us the system of equations which can be used to find individual prices of a bag of popcorn and a drink.

Answer: 2^2x+6 = 2^6

Explanation:

looking at the right of the equal since we can see:

64 is the same as 4^3

but since that answer isn't shown in the multiple choice but we can notice that  64 is the same as 2^6

Now that we know the left side is 2^6 we can see there is similar an answer in the multiple choice. But let's double check that the right side is the same.

Its pretty simple, just make 4 into 2^2 then distribute the exponent of 2 (times the 2 in the exponent to the rest to x+3)

Answer:

y or f(x), depends on the context.

Step-by-step explanation:

When graphing a function, we input a value, x, and output a value, y. This is why we have a coordinate plane.

For example, if we have y = 2x and x=2, our input, then y = 4, our output.

However, if written in function notation, f(x) = 2x, our output will still be 4, except that our output is f(x)

Boden's conjecture is correct

Step-by-step explanation:

we know that

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa.

A right triangle, has two acute angles.

The two acute angles are complementary

so

In any right triangle, the sine of one acute angle is equal to the cosine of the other acute angle

therefore

Boden's conjecture is correct

Answer:

Yes, because the leg opposite one of the acute angles is adjacent to the other acute angle

Step-by-step explanation:

The solutions to quadratic equation are x = 1 and x = -8

Solution:

Given quadratic equation is:

[tex]x^2+7x = 8\\\\x^2 + 7x-8 = 0[/tex]

We have to find the solutions of equation

[tex]\mathrm{Quadratic\:Equation\:Formula:}\\\\\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\text{Compare the given } x^2 + 7x - 8 = 0 \text{ with } ax^2 + bx + c = 0\\\\We\ get\\\\a = 1\\\\b = 7\\\\c = -8[/tex]

[tex]x=\frac{-7\pm \sqrt{7^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}\\\\x =\frac{-7 \pm \sqrt{7^2+4\cdot \:1\cdot \:8}}{2\cdot \:1}\\\\x = \frac{-7 \pm \sqrt{49 + 32}}{2}\\\\Simplify\ the\ equation\\\\x = \frac{-7 \pm \sqrt{81}}{2}\\\\x = \frac{-7 \pm 9}{2}[/tex]

Thus we get two solutions:

[tex]x = \frac{-7+9}{2} \text{ and } x = \frac{-7-9}{2}\\\\x = 1 \text{ and } x = -8[/tex]

Thus the solutions to quadratic equation are x = 1 and x = -8

Answer:

7  

4

Step-by-step explanation:

7+4=11

7-4=3

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations. The two numbers are 7 and 4.

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations.

Let's call the two numbers x and y. We can set up the following equations:

x + y = 11

x - y = 3

Now we can solve this system of equations by adding the two equations together:

(x + y) + (x - y) = 11 + 3

Simplifying, we get:2x = 14

Dividing both sides by 2, we get:x = 7

Now we can substitute this value of x back into one of the original equations to solve for y:7 + y = 11

Subtracting 7 from both sides, we get:y = 4

So, the two numbers are 7 and 4.

Final answer:

Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.

Explanation:

Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.

Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.

Mick therefore ate 4 bananas.

Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.

Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.

Mikey ate 5 bananas.

Mikey the monkey ate more bananas than Mick because 5 is greater than 4.

P= A+B+C

Step-by-step explanation:

A= 52

P= 27.5

================================================

Explanation:

Focus only on the diamond cards. There are 13 of them total. Out of the 13 diamond cards, there is one king of diamonds. So the probability of getting a king, if we know 100% the card is a diamond, is 1/13.

---------------

You can use a slightly longer method through a conditional probability

A = card is a king

B = card is a diamond

P(A and B) = probability of king and diamonds = 1/52

P(A \ B) = probability of event A happens given we know B happens

P(A \ B) = P(A and B)/P(B)

P(A \ B) = (1/52)/(13/52)

P(A \ B) = (1/52) ÷ (13/52)

P(A \ B) = (1/52) * (52/13)

P(A \ B) = 1/13

The probability that the card is a King is 1/13

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

Given that a card is drawn at random from a pack of 52 playing cards, the total outcome is 52

If the card is a king, the expected outcome is 4

Pr(selecting a king) = 4/52 = 1/13

Hence the probability that the card is a King is 1/13

The actual rate of the mortgage is 5.27%.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Since, we're taking two mortgages for a total of $100,000 for 30 years,

Now, we can find the actual rate of the mortgage by finding the weighted average of the two rates.

Hence, The weights in this case will be the proportion of loan taken at each rate;

We have

Rates       Weights      Rates  × Weights

4.15           0.80           4.15 x 0.80 = 3.32

9.75           0.20          9.75 x 0.20 = 1.95

Hence, The actual rate of the mortgage is,

⇒ 3.32 + 1.95

⇒ 5.27%.

Answer:

A sphere.

Step-by-step explanation:

The sun is a sphere.

The best geometric shape to describe the Sun is a sphere, as it appears as a circular disc in the sky and fits with observational data and theoretical models of its structure and the Earth's orbit around it.

When considering the geometric shape that best describes the Sun, we assess its physical appearance and symmetry. The Sun is often depicted in diagrams as having a perfectly round, spherical shape, which aligns with our observations, as it appears as a circular disk in the sky. A sphere is a three-dimensional object where every point on the surface is the same distance from the center, which closely matches the Sun's observed shape. Unlike a triangular prism, cube or cylinder, a sphere has no edges, vertices, or faces, which makes it the best match for the Sun's shape.

Moreover, observations about the Sun, like those represented in figures discussing its structure as well as the Earth's orbit around the Sun, support the description of the Sun as being spherical. The orbit of the Earth itself is very close to a circle, which assumes central body - the Sun - of spherical form to exert a uniform gravitational pull. Additionally, the celestial sphere concept, although now known to be an incorrect model for the universe, also envisions stars, including our Sun, as points on a vast imaginary sphere, once more alluding to the spherical structure of these celestial bodies.

Step-by-step explanation:

It is false because where the 2 is, has to be 3, other wise it won't make sense. Because it will not equal the same thing.

Final answer:

The expression 3a + 3b is not equivalent to 3(a + 2b). The first results in 3a + 3b, while applying the distributive property to the second expression gives 3a + 6b, clearly showing the expressions are different.

Explanation:

The statement 3a + 3b is equivalent to 3(a + 2b) is false. To show this, we can apply the distributive property of multiplication over addition, which states that for any real numbers a, b, and c, a · (b + c) = a·b + a·c. Using this property, we can expand 3(a + 2b) to get 3·a + 3·2b, which simplifies to 3a + 6b. This is not the same as 3a + 3b since 3b is not equal to 6b. Therefore, the expressions are not equivalent.

Answer: he is right the answer is -2

Step-by-step explanation:

The common difference (d) is -2.

In an arithmetic sequence, the common difference (d) is the constant value by which each term differs from the previous term.

To find the common difference in the sequence 100, 98, 96, 94, 92..., we can observe the difference between consecutive terms:

98 - 100 = -2

96 - 98 = -2

94 - 96 = -2

92 - 94 = -2

We see that each term is decreasing by 2. Therefore, the common difference (d) is -2.

Answer:

First term: A(1) = 5

Fourth term: A(4) = 5 1/2

Tenth term: A (10) = 6 1/2

Step-by-step explanation:

Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:

A(n) = 5 + (n-1) (1/6)

First term:

A(1) = 5 + (1-1) (1/6)

A(1) = 5 + (0) (1/6)

A(1) = 5

Fourth term:

A(4) = 5 + (4-1) (1/6)

A(4) = 5 + (3) (1/6)

A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)

Tenth term

A(10) = 5 + (10-1) (1/6)

A(10) = 5 + (9) (1/6)

A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)
