A cafeteria has a special: one hamburger and one order of fries is $5.49, and one hamburger and two orders of fries is $6.99. Determine the price of the hamburger.

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Answer:

A: 80 and B: 5.5

Step-by-step explanation:

For A, just multiply 20 and 4 and which you would get 80 miles. And for B, if 1 inch is equal to 20 miles, you can divide 110 and 20 but the answer will be 5.5 rather than 5.

I think this is right but if you can, try and see if it’s correct later.

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

m = 37.5 (1d.p.)

Given :

• In ∆ JKL , all the three interior angles have equal measures.

• Measure of \( \angle \) 1 ( Exterior angle )

Here, we can solve this question in two ways.

______________________________

Let us calculate the measure of interior angles first.

→ Let the measure of each interior angle be x.

As all the interior angles of the triangle are equal,

\( \sf { \dashrightarrow {180}^{\circ} = {x}^{\circ} +{x}^{\circ}+{x}^{\circ} } \)

[ By angle sum property of ∆ ]

\( \sf { \dashrightarrow {180}^{\circ} = {3x}^{\circ} } \)

\( \sf { \dashrightarrow \dfrac{{180}^{\circ}}{3} = {x}^{\circ} } \)

\( \sf\red { \dashrightarrow {60}^{\circ} = {x}^{\circ} } \)

Therefore, measure of each interior angle of the triangle is 60°.

As we know that,

\( \sf { \dashrightarrow \angle 1 = \angle K + \angle L} \)

\( \sf { \dashrightarrow \angle 1 = {60}^{\circ} + {60}^{\circ} } \)

\( \sf \green { \dashrightarrow \angle 1 = {120}^{\circ} } \)

⇒ Hence, measure of angle 1 is 120°.

→ \(\angle \) 1 + \(\angle \) J = 180°

→ \(\angle \) 1 + 60° = 180°

→ \(\angle \) 1 = 180° - 60°

→\(\angle \) 1 = 120°

⇒ Hence, measure of angle 1 is 120°.

Answer:

I. Length: 43 inches

II. Width: 15 inches

III. Height: 5.5 inches

Step-by-step explanation:

To determine the dimensions of the new box, we need to calculate the space required for a dozen donuts lying flat, including the additional space of one inch.

Since the diameter of each donut is 3.5 inches, the width of the box must be greater than or equal to 3.5 x 4 = 14 inches to accommodate four donuts placed side by side.

Similarly, since the height of each donut is 1.5 inches, the height of the box must be greater than or equal to 1.5 x 3 = 4.5 inches to accommodate three donuts stacked on top of each other.

Finally, since the length of each donut is 3.5 inches, the length of the box must be greater than or equal to 3.5 x 12 = 42 inches to accommodate a dozen donuts lying flat.

Adding one inch to each dimension gives us a final box size of:

Length = 42 + 1 = 43 inches

Width = 14 + 1 = 15 inches

Height = 4.5 + 1 = 5.5 inches

Therefore, the dimensions of the new box should be:

I. Length: 43 inches

II. Width: 15 inches

III. Height: 5.5 inches

Answer:

\(-\frac{4}{15}\)

Step-by-step explanation:

\(\frac{-3}{5} +\frac{1}{3}\)

\(\frac{-9}{15} +\frac{5}{15}\)

\(\frac{-9+5}{15}\)

\(\frac{-4}{15}\)

Answer:

\( \displaystyle{ - \frac{3}{5} + \frac{1}{3} }\)

So,

\( \displaystyle \: \frac{-3 \times 3 + 1 \times 5}{15} \)

\(\displaystyle \frac{-9 + 3}{15} \)

\( \displaystyle \frac{-4}{15} \)

The length of segment NB is 0.833

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area  = 1/2 * 10 * (x + 20 + x - 5)

Area  = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have

x = 0.833

Step-by-step explanation:

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
