Elizabeth bought lemons (l) and apples (a). Each apple costs 35¢ and each lemon costs 15¢. All together, she bought 17 lemons and apples for $3.95. Which system can be used to determine how many of each she bought?

Answers

Answer 1

Step-by-step explanation:

Given:

Lemons - l and apples - aa = 35¢, l = 15¢Number of apples and lemons = 17Cost of lemons and apples = $3.95 = 395¢

System as per question:

a + l = 1735a + 15l = 395

Or

a + l = 170.35a + 0.15l = 3.95
Answer 2

Step-by-step explanation:

Let the number of apples be a and lemons be l . Then ,

=> a + l = 17

Also ,

=> 35a + 15l = $ 3.95

The population of a place was 56000. Next 5 years it is expected to rise by 50%. What will be the population in next 5 years?

Answers

Answer:

84000 people

Step-by-step explanation:

So next 5 year wil be 56000 + 50%

56000 = 100%

50% = 56000 / 2

50% = 28000

56000 + 28000 = 84000

How to lnow the numberof turning points in a function.

The maximum number of turning points of a polynomial function is always one less than the degree of the function. A turning point is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising).

A line has a slope of 1.25 and passes through the point (0, -3). What is the equation of line?

Answers

Answer:

y = 1.25x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1.25 and (0, - 3 ) ⇒ c = - 3

y = 1.25x - 3 ← equation of line

Juan rolls a number cube 40 times, he rolls a 3 on the number cube 6 times. What is the experimental probability that he rolls a 3?

Answers

Answer: 6/40 = 3/20

Step-by-step explanation:

The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:

P= Time the event occurs/ Total number of trials

In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40

because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6

because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40

Answer:

By Both

Step-by-step explanation:

You have all 3 corresponding sides are proportional so you have SSS.  That is

24/8=15/5=18/6

You also have SAS because 15/5=18/6 and you have the angle between the sides that I'm referring to in that proportion.

To prove that the triangles are similar by the SAS similarity theorem the two sides and angles are proportional.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

From definition of similar triangles the 3 corresponding sides are proportional so you have SSS.  

Such that  24/8=15/5=18/6

We also have SAS because 15/5=18/6 and you have the angle between the sides.

Hence, to prove that the triangles are similar by the SAS similarity theorem the two sides and angles are proportional.

The number increased by 25%.

Step-by-step explanation:

If you divide 32 into 40 (40 / 32), it will get you 1.25.

Subtract 1 from 1.25 (1.25 - 1.00) and you'll get 0.25.

Alecia runs the air conditioner im her home when it id hot outside. She uses the equation C = 0.01m to determine the cost , C , in dollars , to run the air conditioner for m minutes . According to the question what is the cost per minute of running alecia’s air conditioner?

Answers

The cost per minute is an illustration of proportionality constant.

The cost per minute is of running Alecia's air conditioner is $0.01

The cost function is given as:

[tex]\mathbf{C(m) = 0.01m}[/tex]

Where C represents the cost, and m represents the number of minutes

A proportional relationship is represented as:

[tex]\mathbf{y =kx}[/tex]

Where k represents the constant of proportion.

So, by comparison:

[tex]\mathbf{k = 0.01}[/tex]

In this case, the proportionality constant is the same as the cost per minute.

Hence, the cost per minute is $0.01

Molly drew a map of her town. She graphed the point L(−1.75, −3) for the library. The ice cream shop is located at L′, a reflection of L across the x-axis. The fire station is located at L′′, a reflection of L′ across the y-axis. Identify the ordered pair that describes the location of the fire station. Express your answer using decimal notation.

(__,__)

Answers

Answer:

(1.75, 3)

Step-by-step explanation:

Let's find L' first: We are reflecting L over the x axis, it means it stays on the same vertical (x=-1.75) and it's y changes sign, going to (-1,75,3).

This new point gets reflected again, over the y-axis. The horizontal coordinate (y=3) remains the same, and  the x coordinate changes sign, going to it's final destination (1,75, 3)

ANSWER:
(1.75, 3)

First, we have to flip (-1.75,-3) over the x-axis, which’ll leave us with (-1.75,3). Then we flip that point over the y-axis, which gives us (1.75, 3).
Just incase you have trouble doing reflections here’s the rules:

reflections over the x axis: (x,y)—>(x,-y)
reflections over the y-axis: (x,y)—>(-x,y)
reflections across y=x: (x,y)—>(y,x)
reflections across y=-x: (x,y)—>(-y,-x)

Step-by-step explanation:

No, it appears to be incorrect if its based off the image you have provided.

I can help you make it correct though.

I'll take you through 2 steps to solve the problem, one being Equations and another being Graphing.

Equations

So, to find the slope, we need to get an equation. Most slope's are in the [tex]y=mx+b[/tex]  form which have a few components that we need to know to figure it out.

[tex]m[/tex] is the slope of the line.[tex]b[/tex] is the y intercept: (0,b)

Now that we know this, we can start breaking i down and soon begin graphing.

The y intercept is one point that we can use to start the line, as the question says to graph the line, we need to start by using the y intercept as one point on the line which would be (0,6) so that would be one point.

Graphing

To graph the line, we need to find the y intercept and another point. For example, we found the y intercept in the previous section, and it was (0,6). We can find another point by just looking at the slope. The slope of the line is 3 so we would go up 3 right 1 from our point to get our second point.

So, our points would be:

(0,6)(1,9)

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 95% pure antifreeze. The company wants to obtain 285 gallons of a mixture that contains 55% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?

Answers

Answer:

premium: 165 gallonswater: 120 gallons

Step-by-step explanation:

Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:

  0.95a +0(285 -a) = 0.55(285)

  a = 0.55/0.95(285) = 165 . . . gallons of 95%

  285 -a = 285 -165 = 120 . . . . gallons of water

There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.

Step-by-step explanation:

Answer:

x = 30

Step-by-step explanation:

The sum of the exterior angle and interior angle of a polygon = 180°

Then the 2 unknown interior angles are

180 - 2x and 180 - (3x - 20) = 180 - 3x + 20 = 200 - 3x

The sum of the 4 interior angles of a quadrilateral = 360°

sum the 4 interior angles and equate to 360

2x + 2x + 10 + 180 - 2x + 200 - 3x = 360 , that is

- x + 390 = 360 ( subtract 390 from both sides )

- x = - 30 ( multiply both sides by - 1 )

x = 30
