Answer:

The quantity of the first model is 150 and the second model is 100 that maximize the profit.

Step-by-step explanation:

Let the quantity of first model = x

Let the quantity of second model = y

The cost of the first model = $100

The cost of the second model = $150

Total number of models = 250 units

Total amount to spend on units = $30000

Now form the equations.

x  +  y  = 250

100x + 150y = 30000

Now solve for the x and y.

x = 250 – y

Now insert this value in the 100x + 150y = 30000.

100(250 –y) + 150y = 30000

25000 – 100y + 150y = 30000

50y = 30000 – 25000

50y = 5000

Y = 100

Now insert the Y in x + y = 250

x = 250 – y

x = 250 – 100

x = 150

Therefore, the first model is 150 units and the second model is 100 units that maximize the profit.

Answer:

Linear relationship.

Step-by-step explanation:

Given that:

Cleansing solution 1 uses 1 part of vinegar with 2 parts water.

Ratio of vinegar to water = 1:2

Cleansing solution 2 uses 2 part of vinegar with 3 parts water.

Ratio of vinegar to water = 2:3

As per a student, the relationship is proportional.

First of all, let us learn about a proportional relationship.

A proportional relationship is the relationship in which the ratios are equal.

OR

In other words, one variable is always a constant value times higher than the other variable.

Here, we have the ratios as 1:2 and 2:3.

One ratio is 0.5 and other ratio is 0.67 which are not equal.

So, it is not proportional relationship.

As we see there is difference of 1 in each ratio.

i.e. Difference in First solution = 2 - 1 = 1

Difference in Second solution = 3 - 2 = 1

So, there is only a constant value change([tex]y = x+c[/tex])  in the other variable when one variable changes by 1.

So, it can be called Linear relationship and this constant is 1.

The equation can be represented as.

[tex]y = x+1[/tex]

where [tex]y[/tex] represents the parts of water in the solution and

[tex]x[/tex] represents the parts of vinegar in the solution.

Answer:

0.6a - 0.5

Step-by-step explanation:

We can expand 0.2(3a - 1) and evaluate 0.3-0.6, getting 0.6a - 0.2 - 0.3.

We can then simplify this expression, getting 0.6a - 0.5.

Answer:

y = 2( x-3)^2 +5

Step-by-step explanation:

The vertex form of a parabolic functions is

y = a( x-h)^2 +k

where (h,k) is the vertex

y = a( x-3)^2 +5

Substituting the point into the equation

13 = a( 1-3)^2 +5

13 = a*( -2)^2 +5

13 = 4a +5

Subtract 5

8 = 4a

Divide by 4

8/4 =a

2=a

y = 2( x-3)^2 +5

Answer: a constant

Step-by-step explanation:

A constant is a numerical expression like 2, 0,78 etc .

A variable is a alphabetical expression that vary like a,b,c,d,x,y,z.

An expression can consists of both numerical and alphabets and also any arithmetic expression like x, 2abc, 6a+2c etc

A term consist of either numbers and variables multiplied together or only numbers or variable like 2xy, x, 2ab etc.

X is all (a term, a variable , an expression) except a constant because a constant is a numerical expression.

Answer: D, a constant

Step-by-step explanation: A constant is an expression without variables.

Answer:

[tex]y=\frac{5}{3}x-5[/tex]

Step-by-step explanation:

Slope-intercept:

[tex]y=mx+b[/tex]

m is the slope and b is the y-intercept. We know that the line passes through the y-axis at -5, so this is the y-intercept (where x is equal to 0). Insert this into the equation:

[tex]y=mx-5[/tex]

With the given information, we can form two points:

[tex](3,0)(0,-5)[/tex]

The first one is the x-intercept and the second the y-intercept. Use these to find the slope:

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}[/tex]

Rise over run is the change in the y-axis over the change in the x-axis, otherwise known as the slope. Insert the appropriate values:

[tex](3_{x1},0_{y1})\\(0_{x2},-5_{y2})\\\\\frac{-5-0}{0-3}[/tex]

Solve:

[tex]\frac{-5-0}{0-3}=\frac{-5}{-3}[/tex]

Note that both the numerator and denominator are negatives. Two negatives make a positive, so:

[tex]\frac{5}{3}[/tex]

The slope is [tex]\frac{5}{3}[/tex]

Insert into the equation:

[tex]y=\frac{5}{3}x-5[/tex]

D. 15x10^20

Step-by-step explanation:

The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.

Hey there!

e15 times 10^20 isn't written in scientific notation. For a number to be in scientific notation, the leading number must be between 1 and 10.

Answer:

Cups of water she needs to make the punch is 12.

Step-by-step explanation:

Amount of water Carson need to make fruit punch = 3 quarts

2 cups is 1 pint

2  pints is 1 quart

1 pint = 1/2 quarts

2 cups is 1 pint which is 1/2 quarts

So, 1 cup:

1 cup is 1/2 times 2 quarts

1 quart is 1 times 2 times 2 cups equals 4 cups

So, 3 quarts equals 3 times 4 cups which equals 12 cups.

So it is 12 cups.

Cups of water she needs to make the punch is 12.

A unit conversion expresses the same property as a different unit of measurement.

Given that, Carson needs 3 quarts of water to make fruit punch, but has only an l-cup measuring cup.

She knows there are 2 cups in 1 pint, and 2 pints in 1 quart.

Amount of water Carson need to make fruit punch = 3 quarts

2 cups is 1 pint

2  pints is 1 quart

1 pint = 1/2 quarts

2 cups is 1 pint which is 1/2 quarts

So, 1 cup:

1 cup is 1/2 times 2 quarts

1 quart is 1 times 2 times 2 cups equals 4 cups

So, 3 quarts equals 3 times 4 cups, which equals 12 cups.

Hence, she need 12 cups.

Answer:

The government paid an interest of $41.9, which is 4.19%

Step-by-step explanation:

Given the 189-day, $1,000 U.S Treasury bill is purchased at a discount of 4.19%, this means that:

It was purchased at a discount of:

4.19% of $1000

= (4.19/100) × 1000

= $41.9

Purchase price = $1000 - $41.9 = $958.1

Because the treasure is sold for $1000 on maturity day, that means the government paid an interest of $41.9, which is 4.19%

B) integer

C) Rational

=========================

The original expression simplifies to -4 which is part of the set of integers {..., -3, -2, -1, 0, 1, 2, 3, ...}

We can write -4 as a fraction of two integers -4 = -4/1, so it is also a rational number.

Because it's rational, it cannot be irrational.

The set of whole numbers is {0, 1, 2, 3, ...} which doesn't involve negative values. If you want to include negative values, then use the set of integers.

Answer:

The correct option is;

69 cm

Step-by-step explanation:

The z-score, or standard score is a measure of how far a data is from the mean

The z-score, is given by the relation;

[tex]z = \dfrac{x- \mu}{\sigma}[/tex]

Z = Standard score

x = Value observed

μ = The mean height of the plants = 52.5 cm

σ = Standard deviation = 7.2 cm

Given that the z-score = 2.25, we have;

[tex]2.25 = \dfrac{x- 52.5}{7.2}[/tex]

Therefore, x = 7.2 × 2.25 + 52.5 = 68.7 cm ≈ 69 cm

Therefore, the minimum required height for this type of plant to be displayed in the main lobby is 69 cm.

Correct Question: If m∠JKM = 43, m∠MKL = (8x - 20), and m∠JKL = (10x - 11), find each measure.

1. x = ?

2. m∠MKL = ?

3. m∠JKL = ?

Answer/Step-by-step explanation:

Given:

m<JKM = 43,

m<MKL = (8x - 20),

m<JKL = (10x - 11).

Required:

1. Value of x

2. m<MKL

3. m<JKL

Solution:

1. Value of x:

m<JKL = m<MKL + m<JKM (angle addition postulate)

Therefore:

[tex] (10x - 11) = (8x - 20) + 43 [/tex]

Solve for x

[tex] 10x - 11 = 8x - 20 + 43 [/tex]

[tex] 10x - 11 = 8x + 23 [/tex]

Subtract 8x from both sides

[tex] 10x - 11 - 8x = 8x + 23 - 8x [/tex]

[tex] 2x - 11 = 23 [/tex]

Add 11 to both sides

[tex] 2x - 11 + 11 = 23 + 11 [/tex]

[tex] 2x = 34 [/tex]

Divide both sides by 2

[tex] \frac{2x}{2} = \frac{34}{2} [/tex]

[tex] x = 17 [/tex]

2. m<MKL = 8x - 20

Plug in the value of x

m<MKL = 8(17) - 20 = 136 - 20 = 116°

3. m<JKL = 10x - 11

m<JKL = 10(17) - 11 = 170 - 11 = 159°
