Answer:

Speed_still  = 12.25 mi/h

Speed_current = 1.75 mi/h

Step-by-step explanation:

In the first trip, the motorboat goes upstream

Speed_boat = Speed_still - Speed_stream

The speed is defined as

Speed = Distance / time

This means

Speed_boat  = 21 miles/ 2 h = 10.5 mi/h

Then

Speed_still - Speed_stream = 10.5 mi/h

In the second trip:

Speed_boat = Speed_still + Speed_stream

Speed_boat  = 21 miles/ 1.5 h = 14 mi/h

Speed_still + Speed_stream = 14 mi/h

Then, the ystem of equations result

Speed_still + Speed_stream = 14 mi/h

Speed_still - Speed_stream = 10.5 mi/h

If we add them together

2*Speed_still  = 24.5 mi/h

Speed_still  = 12.25 mi/h

Speed_stream  = 14 mi/h - 12.25 mi/ h = 1.75 mi/h

ANSWER

[tex]log_{s}(56)[/tex]

EXPLANATION

The given logarithmic expression is:

[tex] log_{s}(4 \times 7) + log_{s}(2) [/tex]

Recall and use the product rule of logarithm

[tex] log_{a}(b) + log_{a}(c) = log_{s}(bc) [/tex]

We apply this rule to obtain,

[tex]log_{s}(4 \times 7) + log_{s}(2) = log_{s}(4 \times 7 \times 2) [/tex]

We multiply out the argument to get;

[tex]log_{s}(4 \times 7) + log_{s}(2) = log_{s}(56) [/tex]

The correct answer is

[tex]log_{s}(56)[/tex]

When the expression Log₅ (4•7) + Log₅ 2 is express as a single logarithm, the result obtained is Log₅ 56

Log₅ (4•7) + Log₅ 2

Log₅ (4 × 7) + Log₅ 2

Log₅ 28 + Log₅ 2

Recall

Log M + Log N = Log MN

Thus,

Log₅ 28 + Log₅ 2 = Log₅ (28 × 2)

Log₅ 28 + Log₅ 2 = Log₅ 56

Thus,

Log₅ (4•7) + Log₅ 2 = Log₅ 56

From the above illustration,

We can conclude that when Log₅ (4•7) + Log₅ 2 is written as a single log, the result is Log₅ 56

Answer:

The value of x is -3

Step-by-step explanation:

We need to solve the given equation and find value of x

5(x-4)+3x-9x=6-(2x+5)+8x

First solving the brackets

5x-20+3x-9x = 6-2x-5+8x

Now combining the like terms,

5x+3x-9x-20 = -2x+8x+6-5

8x-9x-20 = 6x +1

-x-20=6x+1

Now moving x terms on one side and constants on other

6x+x=-20-1

7x = -21

Dividing both sides by 7

7x/7 = -21/7

x = -3

So, the value of x is -3

Answer:

the ordered pair negative 6 over 8, 2 over 8

Step-by-step explanation:

Point P is plotted at the sixth grid line to the left of the y-axis

Going to the left of the y axis means negative, to the right is positive

We go left 6 units, each unit is 1/8

-6 * 1/6 = -6/8

That is the x coordinate

Second grid line above the x-axis.

Going up is positive and down would be negative

We go up 2 units, each unit is 1/8

+2 * 1/8= 2/8

That is the y coordinate

(-6/8, 2/8)

Answer:

Second grid line above the x-axis.

Going up is positive and down would be negative

We go up 2 units, each unit is 1/8

Answer:

Middle Answer.

Step-by-step explanation:

Given that Micah intends to spend less than $150 on paint and brushes

Hence

Cost of brushes+ cost of paint ≤ 150

150 ≥ Cost of brushes+ cost of paint

150 ≥ Cost of brushes+ (price of paint per gal) · (number of gallons)

Given that he buys x gal of paint,

For middle answer:

150 ≥ 42.21 + 21.64x (which matches the inequality in the question, so this is the right answer)

The 42.21 would represent the money spent on paintbrushes. This because the amount of money spent on paintbrushes doesn't change (it's a set amount). You can tell this by the fact that 42.21 is not being multiplied by anything (the 42.21 cannot change at all)

The 21.64x  is the cost of paint per gallon.

Cost of paint per gallon means that the cost changes depending on many gallons you are getting.

The 21.64 represents the cost of 1 gallon of paint, and the 'x' represents the number of gallons.

------------------------------------------------------

So the Answer is option 2:

$42.21 on paintbrushes

Paint costs $21.64 per gallon

Answer:

The arithmetic sequence given above has a first term (a1) equal to 3 and the common difference (d) equal to 6. The sum of the first n terms of the sequence is calculated through  the equation,

                               Sn = (n/ 2) x (2a1 + (n - 1) x d)

Substituting,

                               S22 = (22 / 2) x (2x3 + (22 - 1) x 6) = 1452

Therefore, the answer is the first choice, 1452. 

Step-by-step explanation:

Please mark brainliest and have a great day!

Answer:

1452.

Step-by-step explanation:

Sum of n terms = n/2  [2a1 + d(n - 1) ] where a1 = the first term and d = the common difference.

Here a1 = 3 and d = 9-3 = 6.

So S22 = 11 [2*3 + 6(22-1)]

=  11 * 132

Answer:

1 solution

Step-by-step explanation:

The number of solutions will be one.

( i.e. the system of equation has a unique solution )

We are given a system of equations such that:

One of the equation has a negative reciprocal slope as compared to the other.

This means that the two lines are perpendicular.

Hence, the two lines will definitely meet or intersect at just one point and at right angles.

Also we know that the solutions  of a system of linear equations are the points where the two lines intersect.

Hence, we will have just one solution.

( since here the two lines will intersect at just one point )

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

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

We have the points C(3, -5) and D(6, 0).

Substitute:

[tex]m=\dfrac{0-(-5)}{6-3}=\dfrac{5}{3}[/tex]

use (6, 0):

[tex]y-0=\dfrac{5}{3}(x-6)[/tex]

Convert to the standard form [tex]Ax+By=C[/tex]:

[tex]y=\dfrac{5}{3}(x-6)[/tex]       multiply both sides by 3

[tex]3y=5(x-6)[/tex]            use the distributive property

The mean and standard deviation of both change ages in the room.

The mean of a dataset exists as the sum of all values divided by the total number of values. It's the most generally utilized measure of central tendency and exists often referred to as the “average.”

The median exists as the middle value in a list ordered from smallest to largest. The mode exists as the most frequently occurring value on the list.

The standard deviation exists as a statistic that measures the dispersion of a dataset relative to its mean and is computed as the square root of the variance. The standard deviation exists estimated as the square root of variance by determining each data point's deviation relative to the mean.

Standard deviation describes how spread out the data is. It is a measure of how far each observed value exists from the mean.

Table N 4

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

Verify the table 4

For x=1, y=2

so

y/x=2/1=2

For x=2, y=4

so

y/x=4/2=2

For x=3, y=6

so

y/x=6/3=2

therefore

The constant of proportionality k is equal to 2 and the equation is equal to

y=2x

The table 4 represent a direct variation, therefore is a possible ratio table for ingredients X and Y

Answer:

The correct option is 4.

Step-by-step explanation:

It given that recipe ingredients remain in a constant ratio no matter how many servings are prepared.

It means the relation between x and y is

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

where k is constant of proportionality.

We need to find a possible ratio table for ingredients X and Y for the given number of servings.

In table 1,

[tex]\frac{y_1}{x_1}=\frac{2}{1}[/tex]

[tex]\frac{y_2}{x_2}=\frac{3}{2}[/tex]

[tex]\frac{y_3}{x_3}=\frac{8}{3}[/tex]

[tex]\frac{y_1}{x_1}\neq \frac{y_3}{x_3}[/tex]

Option 2 is incorrect.

In table 3,

[tex]\frac{y_1}{x_1}=\frac{2}{1}[/tex]

[tex]\frac{y_2}{x_2}=\frac{3}{2}[/tex]

[tex]\frac{y_1}{x_1}\neq \frac{y_2}{x_2}[/tex]

Option 3 is incorrect.

In table 4,

[tex]\frac{y_2}{x_2}=\frac{4}{2}=2[/tex]

[tex]\frac{y_3}{x_3}=\frac{6}{3}=2[/tex]

[tex]\frac{y_}{x_1}=\frac{y_2}{x_2}=\frac{y_3}{x_3}[/tex]

Option 4 shows a possible  ratio table for ingredients X and Y for the given number of servings.

Therefore the correct option is 4.

Answer:

To be determined (picture???)

Step-by-step explanation:

SSS means: side - side - side

This means that when you look at the two triangles, in this case ABC and ADC their sides MUST be corresponding to be congruent (equal). This is easily identifiable by the tics or little dash marks you see on the triangles. If the dashes correspond to the same sides (hence side-side-side rule) then the theorem is proven correct and the triangles of congruent. Take a look at the attached image for an example :D

Step-by-step answer:

Given:

In a triangle ABC, AD is the bisector of angle A ....If AB=5.6cm ,AC=4cm and DC=3cm, find BD and DC

This problem can be solved by direct application of the angle bisector theorem, which states that the division of the side opposite to the bisected angles is proportional to the respective sides.

Here we have:

Bisector: AD

Side divided: DC = 3 cm

Length of AB = 5.6

Length of AC = 4.0

Then BD = AB/AC * DC = 5.6/4.0 * 3 = 4.2

BC = BD+DC = 4.2+3 = 7.2
