Using the elimination method, the price of one t-shirt is $30 and one key-chain is $11.

In the given question, Elizabeth's family went to NYC for their vacation.

At the gift shop on Liberty Island, Valerie bought three t-shirts and four key chains for $134, and Jennifer bought four t-shirts and five key chains for $175.

We have to find the price of each item.

Let the price of one t-shirt = $x

Let the price of one Key chain = $y

According to question

Price of three t-shirts and four key chains = $134

So the equation is

3x + 4y = $134……………….(1)

Also,

Price of four-shirts and five Key chains = $175

So the equation is

4x+5y = $175……………………..(2)

Now solving the equation using the elimination method.

Multiply Equation (1) by 5 and Equation (2) by 4, we get

15x+20y = 670....................(3)

16x+20y = 700......................(4)

Subtract equation 4 and 3, we get

x = 30

Now put the value of x in equation 1,

3*30 + 4y = $134

90+4y=$134

Subtract 90 on both side, we get;

4y = 44

Divide by 4 on both side, we get;

y = 11

Hence, the price of one t-shirt is $30 and one key-chain is $11.

Answer:50 degree

Step-by-step explanation:

It is an isosceles triangle so two sides and angles are equal. The first line is facing the first angle so the second angle ( m<DEF) = 65 degrees because both angles are equal.

This implies that m<FED =

65 + 65+ <FED= 180( sum of angle in a triangle)

130 + <FED=180

<FED= 180- 130

<FED= 50 degree

The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

Since csc^2 x is the reciprocal of sin^2 x, we can rewrite the equation as P = I^2_0 R (csc^2 2 pi ft). This expression represents the power delivered to the resistance in terms of csc^2 2 pi ft.

Therefore, the correct expression for the power delivered to the resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

Answer:

There are 25 inches in the larger dimension.

Step-by-step explanation:

∵ 1 foot = 12 inches

∵ The small dimension after enlargement is 1 foot and 3 inches

→ Change it to inches only

∴ The small dimension = 1(12) + 3 = 12 + 3

∴ The small dimension = 15 inches after enlarged

∵ The small dimension of the photo before enlarged = 3 inches

→ Divide its length after enlarged by its length before enlarged to

   find the scale of the enlargement

∵ 15 ÷ 3 = 5

∴ The scale of enlarged is 5

→ To find the larger dimension after enlarged multiply its length

   before enlarged by 5

∵ The larger dimension before enlarged = 5 inches

∴ The larger dimension after enlarged = 5 × 5

∴ The larger dimension after enlarged = 25 inches

∴ There are 25 inches in the larger dimension.

Answer: The solution for w, expressed as a natural logarithm, is:

w = ln(88/3) / 5

Step-by-step explanation: Starting with the given equation:

-3e^(5w) = -88

Dividing both sides by -3:

e^(5w) = 88/3

Taking the natural logarithm of both sides:

ln(e^(5w)) = ln(88/3)

Using the property that ln(e^x) = x:

5w = ln(88/3)

Finally, solving for w by dividing both sides by 5:

w = (1/5)ln(88/3)

So the solution for w, expressed as a natural logarithm, is:

w = ln(88/3) / 5

The value that make the function continuous everywhere are:

To find the values of a, b, and c that make the given functions continuous everywhere, ensure that the function values from the left and right sides of the points of discontinuity match.

For f(x) = kx², x ≤ 3; 4x - 11, x > 3:

Two parts of the function to agree at x = 3,

Solving for k:

k(3)² = 4(3) - 11

9k = 12 - 11

9k = 1

k = 1/9

Therefore, the value of k that makes the function continuous everywhere is k = 1/9.

For g(x) = cx², x < 1; 4, x = 1; -x³ + kx, x > 1:

Two parts of the function to agree at x = 1.

Solving for c:

c(1)² = -1³ + k(1)

c = -1 + k

Therefore, the value of c that makes the function continuous everywhere is c = -1 + k.

For h(x) = π, x < 0; x² + ax + b, 0 ≤ x ≤ 1; 6x + 5, x > 1:

Three parts of the function to agree at their boundaries.

Solving for a and b:

0² + a(0) + b = π

b = π

1² + a(1) + b = 6(1) + 5

1 + a + π = 6 + 5

a = 10 - π

Therefore, the values of a and b that make the function continuous everywhere are a = 10 - π and b = π.

For f(x) = x², x < 1; sin(bx), x ≥ 1:

Two parts of the function to agree at x = 1.

Setting them equal and solving for b:

1² = sin(b(1))

1 = sin(b)

The system of equations [x - 3y = -1 and -6x + 19y = 6] can be solved, resulting in x = -1 and y = 0.

To solve the system of equations [x - 3y = -1 and -6x + 19y = 6], we can use the method of substitution or elimination.

Let's solve it using the method of elimination.

First, we can multiply the first equation by 6 and the second equation by -1 to eliminate the x terms.

This gives us [6x - 18y = -6 and 6x - 19y = -6].

Now, subtracting the first equation from the second eliminates the x terms, leaving us with -y = 0. Solving for y, we find y = 0.

Substituting this value back into the first equation, we get x - 3(0) = -1, which simplifies to x = -1.

Therefore, the solution to the system of equations is x = -1 and y = 0.

If the lengths of all the sides of a polygon are tripled, but the angles remain the same, the area of the polygon will increase by a factor of 9. This is because the area of a polygon is directly proportional to the square of its side length. Therefore, tripling the side lengths will increase the area by a factor of 3^2, which is 9.

When the lengths of all the sides of a polygon are tripled while the angles remain the same, the new polygon will be similar to the original one but with larger sides. To determine what happens to the area of the polygon in this case, let's consider the following steps:

1. All the sides of the polygon are tripled. This means that each side's length is now 3 times its original length.

2. The angles of the polygon remain the same, so the overall shape is preserved.

3. To find the area of the new polygon, we can use the formula for the area of a similar polygon: (New area) = (scale factor)^2 * (Original area), where the scale factor is the ratio of the new side length to the original side length.

4. In this case, the scale factor is 3 (since the lengths of the sides are tripled). So, we have (New area) = (3)^2 * (Original area).

5. Therefore, the new area is 9 times the original area.

In conclusion, when the lengths of all the sides of a polygon are tripled and the angles remain the same, the area of the polygon increases by a factor of 9.

What is the slope intercept form of a line ?

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

The equation of a line which is passing through point (1 , -17) with slope m = 4 can be found by using the slope intercept form which is given by :

y = mx + c

Here ; m is the slope and c is the y - intercept of the line.

So ;

The point given is (x , y) = (1, -17) and slope m = 4. Let's use these values to find out the equation of the line. But before that let's find out the value of y-intercept (c).

-17 = (4 × 1) + c

c = - 17 - 4

c = -21

The error bound will be 0.877 with the sample mean being 13.30 with a sample standard deviation of 1.55.

To find the error bound, we need to calculate the margin of error, which is the maximum likely difference between the true population mean and the sample mean. We can find this using the formula:

Margin of error = z* (standard deviation / sqrt(sample size))

Where z* is the critical value of the standard normal distribution that corresponds to the desired confidence level.

Since the confidence level is 95%, we can use the z* value of 1.96, which represents the number of standard deviations from the mean that includes 95% of the population.

Plugging in the values we have:

Margin of error = 1.96 * (1.55 / sqrt(12))

Simplifying this, we get:

Margin of error = 1.96 * 0.448 = 0.877

Therefore, the error bound is 0.877. This means we can be 95% confident that the true population means for the amount of soda served in the 16 oz. serving size falls within the range of 13.30 ± 0.877, or between 12.423 and 14.177.

If two figures are similar, then the ratios of its corresponding sides is equal

Find the lake frontage (to the nearest tenth) of each lot shown

we have that

174/(48+55+61) = A/48 = B/55 = C/61

174/164 = A/48 = B/55 = C/61

step 1

leak frontage of lot A

174/164 = A/48

A = 174 × 48/164 = 50.9 yd

Step 2

leak frontage of lot B

174/164 = B/55

A = 174 × 55/164 = 58.4 yd
