which is true about the functional relationship shown in the graph

Answer: Hence, his evening sales were $630.

Step-by-step explanation:

Let the sales in the morning be 'x'

Let the sales in afternoon be x+50

Let the sales in the evening be 3(x+50).

Total sales for the day = $1000

According to question, it becomes

[tex]x+x+50+3(x+50)=1000\\\\2x+50+3x+150=1000\\\\5x+200=1000\\\\5x=1000-200=800\\\\x=\dfrac{800}{5}\\\\x=160[/tex]

So, his evening sales would be

[tex]3(x+50)\\\\=3(160+50)\\\\=3\times 210\\\\=630[/tex]

Hence, his evening sales were $630.

Answer:

∠DAB

Step-by-step explanation:

A supplement to an angle is one that will sum to 180° with the given angle.  ∠ABC is 110°; this means its supplement will be 180-110 = 70°.

The angle in the quadrilateral that is 70° is ∠DAB.

The width of the rectangle can be any number less than or equal to 15 inches. If the width also must be at least 10 inches and a whole number, then it can be any of the whole numbers between 10 and 15, inclusive.

You're correct, the initial inequality does solve for w, the width of the rectangle. The inequality 80 - 2w ≥ 50 simplifies to 2w ≤ 30 and further simplified to w ≤ 15. This means that the width of the rectangle can be any number less than or equal to 15 inches.

For the second part of the question, if we also know that the width must be at least 10 inches and it must be a whole number, we can adjust the solution to be an integer number between 10 and 15, inclusive. So the possible values for width would be 10, 11, 12, 13, 14, or 15 inches in this case.

https://brainly.com/question/30013680

#SPJ12

To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. If the width must be at least 10 inches and a whole number, then the solution changes.

To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. We can do this by adding 2w to both sides of the inequality:

80 - 2w + 2w ≥ 50 + 2w
80 ≥ 50 + 2w
30 ≥ 2w
15 ≥ w

So, the width of the rectangle must be less than or equal to 15 inches.

If the width must be at least 10 inches and a whole number, then the solution changes. In this case, w can only take on whole number values from 10 to 15, inclusive. So, the width of the rectangle can be 10, 11, 12, 13, 14, or 15 inches.

Answer:

Step-by-step explanation:

Alright, lets get started.

Since we know,

[tex]3.28084 feet = 1 meter[/tex]

So,

[tex]1 feet = \frac{1}{3.28084} meter[/tex]

[tex]1 cubic feet= \frac{1}{3.28084} *\frac{1}{3.28084}* \frac{1}{3.28084}cubic meters[/tex]

Hence

[tex]1 cubic feet = 0.0283168 cubic meters[/tex]

So, 30000 cubic feet = [tex]30000*0.0283168 = 849.5[/tex] cubic meters

Final answer:

The measure of ∠CAE is found by adding ∠CAB to half of ∠ABC. Since ∠ABC is 30° (calculated from the triangle angle sum), ∠ADE is 15°. Therefore, ∠CAE is 97°.

Explanation:

To find the measure of m∠CAE, let's use the information provided. Since DE is the perpendicular bisector of AB, we know that ∠ADE is a right angle (90°).

In ΔABC, the sum of the angles is 180°. We have m∠CAB = 82° and m∠C = 68°. To find m∠ABC, we subtract these from 180°:

180° - 82° - 68° = 30°

Since DE is the perpendicular bisector, ∠ADE is half of ∠ABC, thus:

∠ADE = 30° / 2 = 15°

Finally, we find m∠CAE by adding ∠CAB to ∠ADE:

m∠CAE = 82° + 15° = 97°

Final answer:

To find angle CAE, we use the properties of perpendicular bisectors and the given angles to determine that m∠CAE = 41°.

Explanation:

In triangle ABC, the perpendicular bisector of side AB intersects side AB at point D and side BC at point E. To find angle CAE, we need to use the properties of perpendicular bisectors and the given angles.

The perpendicular bisector of AB passes through the midpoint of AB, which is also equidistant from A and B. This means that CD is an angle bisector of angle CAB. Since the perpendicular bisector of AB is also perpendicular to AB, we have m∠CAD = m∠CAB/2 = 41°.

Since AC is a common side, triangles ACD and ACE share two congruent angles (m∠CAD and m∠CAE), making them similar. We can use the property of corresponding angles in similar triangles to find m∠CAE = m∠CAD = 41°.

Step-by-step explanation:

Given : Function  [tex]y=2x^3-x^2-4x+5[/tex]

To find : Over which interval is the function decreasing?

Solution :

First we plot the graph using graphing calculator.

Refer the attached figure below.

Now, Examining the graph

From [tex]-\infty[/tex] to (-0.667,6.63) the graph is increasing as the curve is increasing.

From (-0.667,6.63) to (1,2) the graph decreasing as the curve is decreasing.

From  (1,2) to [tex]\infty[/tex] the graph is increasing as the curve is increasing.

So, The interval in which the function is decreasing is given by (-0.667,1)

Round to nearest tenth,  (-0.7,1)

Therefore, Option 3 is correct.

To solve problems with integers and rational numbers, one should apply operations' properties such as commutativity, associativity, and distributivity, which streamline calculations and assist in combining numbers in an order that simplifies the process.

Integers and rational numbers are essential elements of algebra that allow for diverse mathematical operations. Integers are the set of whole numbers including zero, and their negative counterparts (e.g., -1, 0, 1), while rational numbers are ratios of integers (e.g., 2/1, 3/4) that can represent fractions and decimals that terminate or repeat. When solving problems, it is crucial to remember the properties of operations, which include commutativity associativity , distributivity, the additive inverse and the multiplicative inverse.

For example, when adding fractions with different denominators, you find a common denominator and use commutativity and associativity to combine these fractions. A problem involving multiplication of a negative integer and a fraction may require both the distributive property and understanding of the multiplicative inverse. Mastering these properties provides a foundation for solving algebraic expressions and equations, ensuring accuracy whether the numbers are complex, real, rational, or integers.

The average rate of change in the cost of the pizza from an 8-inch to a 16-inch pizza is 0.9425.

Given that:

There are five sizes of pizza.

Personal of size 8 inches, small size of 10 inches, medium size of 12 inches, large size of 14 inches, and extra large size of 16 inches.

The cost of the pizza is a function of the diameter.

Also, a table is given that shows the diameter of the pizza and the cost of the pizza based on the diameter.

From the table:

Cost of 8-inch pizza = 2.51
