15 kilograms of the first type should be mixed with 25 kilograms of the other kind

If the blend costs  $5.50/kg, then:

on each kg at $5.00/kg, gain = $0.50  ($5.50 - $5.00)

on each kg at $5.80/kg, loss = $0.30  ($5.50 - $5.80)

Hence 3kg of the first kind must be mixed with 5kg of the second so that the gain on the first (3 x $0.50) is exactly the same as the loss on the second (5 x $0.30)

The required proportion is 3:5

In order to find how many kilograms of each type are needed to make 40kg, we will use the proportion obtained:

We have 3:5, total share = 3+5 = 8

First kind share = 3/8 x 40 kg = 15 kg

Second kind share = 5/8 x 40 kg = 25kg

Therefore, 15  kilograms of the first type is needed and 25 kilograms of the other kind is needed

The percent increase in the median monthly rent prices is 14.3%

From the information, the median monthly rent in 2005 was $694 and $810 in 2010.

The increase in the amount will be:

= $810 - $694.

= $116

The percent increase in the median monthly rent prices from 2005 to 2010 will be:

= Increase in amount / Old rent × 100

= 116/810 × 100

Answer:

NOT CONGRUENT

Step-by-step explanation:

There are several types of congruence:

ASA - Angle Side Angle

AAS - Angle Angle Side

HL - Hypotenuse Leg

This image shows two triangles which have 2 congruent sides and one congruent angle.

Is it ASA?

There is only one congruent angle, so this cannot be congruent by ASA

Is it AAS?

By the same reasoning, it cannot be congruent by AAS.

Is it HL?

Although there are 2 congruent sides, neither one is the hypotenuse. Is is not congruent by HL.

There is no such thing as SSA congruence, because it is actually possible to have 2 non-congruent triangles who have 2 congruent sides and 1 congruent angle. Therefore, these are NOT CONGRUENT

The expression that represents the quotient of the given model is x + 5. The correct option is C. x + 5

From the question, we are to determine the expression that represent the quotient of the given model

From the given model, we can write that

x | x² + x + x + x + x + x

Dividing by using the long division

  x + 1 + 1 + 1 + 1 + 1      

x | x² + x + x + x + x + x

Thus, the quotient of the expression is

x + 1 + 1 + 1 + 1 + 1

Further simplification,

NOTE: 1 + 1 + 1 + 1 + 1 = 5

Then,

The expression x + 1 + 1 + 1 + 1 + 1  becomes

x + 5

Hence, the expression is x + 5

Applying the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

There are 4 different pairs of lines given to us.

We have to find out the pair of lines that are perpendicular to each other.

We know that the general equation of a line in slope-intercept form is represented as -

y = mx + c --- (1)

where

(x, y) = coordinates of the lines

m = slope of the line

c = y-intercept

It is also known to us that for two lines to be perpendicular the product of their slope must be equal to -1.

A. y = -8 and y = 2

Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.

So, these two pair of lines are not perpendicular.

B. x = 4 and y = -1

Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.

So, these two pair of lines are not perpendicular.

C. x - y = 7 and y = x + 3

Now, x - y = 7

=> -y = 7 - x

=> y = x - 7

Comparing this to the equation (1), we have slope of the line, m = 1.

Also, y = x + 3

Comparing this to the equation (1), we have slope of the line, m = 1.

We see that the product of the slope of these pair of lines is not equal to -1.

So, these two pair of lines are not perpendicular.

D. y = -4x + 1 and 8x + 2y = -10

Now, y = -4x +1

Comparing this to the equation (1), we have slope of the line, m = -4.

Also, 8x + 2y = -10

=> 2y = -8x - 10

=> y = -4x - 10

Comparing this to the equation (1), we have slope of the line, m = -4.

We see that the product of the slope of these pair of lines is not equal to -1.

So, these two pair of lines are not perpendicular.

Thus, according to the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

Answer:

Below

Step-by-step explanation:

All of the angles labeled sum up to a right angle = 90 °

x+4     +      x+4        +  x+4      = 90

3x + 12 = 90

3x = 78

x = 26°

Answer:

x = 26

Step-by-step explanation:

from the diagram

∠ BFC + ∠ CFD + ∠ DFE = ∠ BFE , that is

x + 4 + x + 4 + x + 4 = 90

3x + 12 = 90 ( subtract 12 from both sides )

3x = 78 ( divide both sides by 3 )

x = 26

What is the unit rate?

A unit rate is a cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.

From the table,

For 0 hours, distance = 15 miles

For 1 hour, distance = 80 miles

Difference between distances= 80-15=65 miles

Since it is given that, it is at a constant rate,  for every hour there is an increase of 65 miles in distance.

Step-by-step explanation:

You want the coordinates of the points on the curve y = x³ +3 where the tangent lines are parallel to y = 12x -1.

The slope of the tangent line is the x-coefficient in its equation: 12.

The slope of the curve is given by its derivative:

  y' = 3x²

We want the x-values where the slope is 12. These are the solutions to ...

  12 = 3x²

The model’s distances isn't proportional to the actual dimensions of the solar system as B. No, because the ratios of model length to actual distance are different for the two planets.

Ratio demonstrates how many times one number can fit into another number. It is used to show the comparison between two or more things

In this case, in model, the distance from the sun to Earth is 7 inches and the distance from the sun to Neptune is 19 inches. This can be illustrated as:

= 7/19

= 0.368

If the actual distance from the sun to Earth is 91.549 million miles and the actual distance from the sun to Neptune is 2,780.5 million miles, the ratio is:

= 91.549 / 2780.5

Solution:

First of all to solve the Linear Inequality we need to plot the graph of the given equations.

To maximise the equation P = 30x + 40y

we need to find the corner values of x and y.

According to the graph, the corner values of (x,y) are

(5,0), (3,4) and (0,7)

putting the values in the equation P = 30x + 40y

Answer: y=-2x²-6x

Step-by-step explanation:

Its x-intercepts are 0 and -3, and the graph goes through the point (-1,4)

Hence we have three coordinates of the equation y=ax²+bx+c    (1):

                                    (0,0)   (-3,0)   (-1,4)

Let's substitute these coordinates into formula (1):

[tex]0=a(0)^2+b(0)+c\\0=a(-3)^2+b(-3)+c\\4=a(-1)^2+b(-1)+c\\\\0=0+0+c\\0=9a-3b+c\\4=a-b+c\\\\0=c\\0=9a-3b+0\\0=a-b+0\\\\c=0\\9a-3b=0\ \ (1)\\a-b=4\ \ \ \ \ (2)\\\\c=0\\\\[/tex]

Divide both parts of the equation (1) by 3 and multiply both parts of the equation (2) by -1: :

[tex]3a-b=0\\-a+b=-4\\\\[/tex]

Sum these equations:

[tex]2a=-4[/tex]

Divide both parts of the equation by 2:

[tex]a=-2[/tex]

We substitute the value of a=-2 into equation (2):

[tex]-2-b=4\\[/tex]

Divide both parts of the equation by -1:

[tex]2+b=-4\\\\2+b-2=-4-2\\\\b=-6[/tex]

[tex]Thus, \\\\y=-2x^2-6x+0\\\\y=-2x^2-6x[/tex]

Considering the sine function in this problem, we have that:
