PLEASE HELP, WILL MARK BRAINLIEST!! The diagram shows the dimensions of a deck. A student finds the area by adding 16 ft^2 + 48 ft^2. Is the student correct? Explain your reasoning.

Answer:

x = [tex]\frac{12}{17}[/tex] or 0.706

[tex]y = \frac{59}{34}[/tex] or 1.735

Step-by-step explanation:

5x + 2y=7    ----->(eq 1)

- 2x + 6y=9 ----->(eq 2)

Multiply (eq 1) with 3

3×(5x + 2y) = 3×7  

15x + 6y = 21  ----->(eq 3)

substract (eq 3) from (eq 2)

- 2x + 6y - (15x + 6y) = 9-21

- 2x + 6y - 15x - 6y = 9-21

- 2x - 15x + 6y - 6y = 9-21

-17x = -12

x = -12 ÷ -17

x = [tex]\frac{12}{17}[/tex]

put x = [tex]\frac{12}{17}[/tex] in (eq 1)

[tex]5*\frac{12}{17} + 2y = 7[/tex]

[tex]2y = 7- 5*\frac{12}{17}[/tex]

[tex]2y = \frac{7*17 - 60}{17}[/tex]

[tex]2y = \frac{119- 60}{17}[/tex]

[tex]2y = \frac{59}{17}[/tex]

[tex]y = \frac{59}{17*2}[/tex]

[tex]y = \frac{59}{34}[/tex]

Answer:

339.35

Step-by-step explanation:

The amount of money the credit card customer still owes to pay is $339.35.

We are given that,

The amount the credit card customer owes = $523.85.

The amount the credit card customer paid = $184.50.

We have to find the amount of money the credit card customer still owes to pay.

The amount of money the credit card customer still owes to pay :

= The amount the credit card customer owes - The amount the credit card customer paid

= $523.85 - $184.50

= $339.35

Thus, the amount of money the credit card customer still owes to pay after paying $184.50 is $339.35.

The 3 statements that are correct about the graph are:

1. "Plan A offers fewer movies than Plan B for monthly costs greater than 20$"

2. "The two plans cost the same for 10 movies per month"

3. "The two plans offer the same number of movies for 20$ a month."

In terms of  the above, the graph shows Plan A's line is consistently lower than Plan B's before the equilibrium point. Hence, statement 1 is true.

From the image, one can locate where Plan A and Plan B intersect on the graph at around 10 movies per month, as both plans cost the same. So when you follow the line to the cost axis,  Plan A and Plan B have the same monthly cost so statement 2 is true.

Answer:

(-4, -1)

Step-by-step explanation:

x = 4y

-4x - y = 17

Plug in 4y for x in the second equation:

-4(4y) - y = 17

Simplify. Remember to follow PEMDAS. Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.

First, multiply 4y with -4:

-4(4y) = -16y

-16y - y = 17

Simplify. Combine like terms:

-16y - y = 17

-17y = 17

Isolate the variable, y. Divide -17 from both sides:

(-17y)/-17 = (17)/-17

y = 17/-17

y = -1

Plug in -1 for y in the first equation:

x = 4y

x = 4(-1)

x = -4

x = -4, y = -1

Answer: (-4, -1)

Since both have the same interquartile range, the inference made would be: types of cars sold in the two months typically get about the same gas mileage.

The interquartile range is a measure of variability, which can be used in comparing two data distribution.

Interquartile range = Q3 - Q1.

Interquartile range for gas mileage of cars sold in June = 33 - 21 = 12.

Interquartile range for gas mileage of cars sold in December = 26 - 14 = 12.

The expression for the area of a rectangle with dimensions (3x-1) and (x+6) is obtained by multiplying these dimensions, resulting in the quadratic expression 3x² + 17x - 6.

The dimensions of the rectangle given here are (3x-1) and (x+6). The area of a rectangle can be calculated using the formula length x width. Thus, to obtain an expression for the area of the rectangle, multiply the length (3x-1) by the width (x+6). This results in the expression (3x² - x + 18x - 6). Simplifying this expression, we get 3x² + 17x - 6 as the area of the rectangle in polynomial form, which is a quadratic expression.

https://brainly.com/question/15218510

#SPJ12

Final answer:

The area of the rectangle with dimensions 3x-1 by x+6 is given by the polynomial 3x² + 17x - 6 in standard form.

Explanation:

To find the expression for the area of the rectangle given the dimensions 3x-1 and x+6, we need to multiply the length by the width. The area A is given by the formula A = length × width, thus:
A = (3x - 1)(x + 6)

Distribute the terms to obtain the polynomial:
A = 3x(x) + 3x(6) - (x) - (6)

Simplify and combine like terms to express in standard form:
A = 3x² + 18x - x - 6

A = 3x² + 17x - 6

Therefore, the expression for the area of the rectangle, written as a polynomial in standard form, is 3x² + 17x - 6.

Answer:

the answer is  about 4.243

Step-by-step explanation:

Squares mean all sides would have the same length. So you just need to find the square root of the area (18)  which is about 4.243 and just to check multiply 4.243 by itself and you would get 18.

Final answer:

The length of one side of the table top with an area of 18 square feet is approximately 4.24 feet, as calculated by taking the square root of the area.

Explanation:

To find the length of one side of a table top with an area of 18 square feet, we should understand that a square has all sides of equal length. Therefore, to find the side length of a square, we take the square root of the area. In this case, we have an area of 18 square feet, so the calculation would be √18, which is approximately 4.24 feet. Thus, the length of one side of the table top is approximately 4.24 feet.

C. For an equal number of servings, the bananas will have three times as much sugar.

Step-by-step explanation:

This is because the amount of sugar will change proportionally with the number of servings, so the ratio of sugar in bananas and in carrots will stay the same as long as the serving size is equal. For example, three servings of bananas would have 45 grams of sugar and 3 servings of carrots would have 15 grams of sugar. If you divide these you will still get a ratio of 1/3, which makes this statement true. Hope this helps! :)

Answer: No .

Step-by-step explanation:

If we make two triangles with lengths of 4 centimeters and 2 centimeters and  an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.

According to the definition of congruence , if two shapes are congruent then they have equal size and shape.

i.e. they look exactly same.

It means only one triangle is possible with the given measurement .

No, only one triangle can be drawn with side lengths of 4 centimetres, 2 centimetres, and an included angle of 50°.

To determine if more than one triangle can be drawn with given side lengths and an included angle, we can use the Side-Angle-Side (SAS) congruence postulate.

According to this postulate, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Given:

One side length is 4 cm (side a).

Another side length is 2 cm (side b).

The included angle between these two sides is 50° (angle C).

Using the Law of Cosines, we can find the length of the third side (side c) of the triangle. The Law of Cosines states that for any triangle with sides a, b, and c, and the angle opposite side c being the following equation holds: [tex]\[ c^2 = a^2 + b^2 - 2ab \cos(\gamma) \][/tex]

Substituting the given values:

[tex]\[ c^2 = 4^2 + 2^2 - 2 \cdot 4 \cdot 2 \cdot \cos(50^\circ) \][/tex]

[tex]\[ c^2 = 16 + 4 - 16 \cdot \cos(50^\circ) \][/tex]

[tex]\[ c^2 \approx 20 - 16 \cdot 0.6428 \][/tex]

[tex]\[ c^2 \approx 20 - 10.2848 \][/tex]

[tex]\[ c^2 \approx 9.7152 \][/tex]

[tex]\[ c \approx \sqrt{9.7152} \][/tex]

[tex]\[ c \approx 3.118 \text{ cm} \][/tex]

Hence, the answer is no; only one triangle can be drawn with side lengths of 4 centimetres, 2 centimeters, and an included angle of 50°.

Answer:

B. 98

Step-by-step explanation:

Have a nice day!

Based on the inscribed angle theorem, the measure of arc ECF in circle (G) is equal to: B. 98 degrees.

The inscribed angle theorem states that the measure of an inscribed angle whose vertex lies on a circle is half of the intercepted arc subtended at a point on the circle.

Given the following data:

By using the inscribed angle theorem, we would find the intercepted arc as follows:

∠DEF = ∡DF/2

79 = ∡DF/2

∡DF = 2 × 79

∡DF = 158 degrees.

Now, we can determine measure of arc ECF:

∡ECF + ∡DF + ∡DE = 360

∡ECF + 158 + 104 = 360

∡ECF + 262 = 360

∡ECF = 360 - 262

∡ECF = 98 degrees.
