Answer:

2,375,000

Step-by-step explanation:

From the question,

A map has a scale of 1: 1250000.

We are told that:

On a map, The cave of truth is 1.9cm away from the waterfall of dreams.

How far away are they in real life?

This is calculated as:

1 = 1250000

1.9 = x

Cross Multiply

x = 1.9 × 1250000

x = 2,375,000

Therefore, there distance in real life = 2,375,000

Answer:

log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Step-by-step explanation:

for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477

and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219

Step-by-step explanation:   Using Properties of Logs

logb(x/y) = logbx - logby.

Furthermore

log5 (4/7)= log5 (4)- log5 (7)

Solve log 5 (4) and log 5 (7)  with the base change of the logarithm

log 5 4 = log 4 / log 5

Use the calculator (DESMOS):  log 5 4 =0.8613531161

log 5 7 = log 7 / log 5

log 5 7 =1.2090619551

Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Answer:

The value of x is 120°

Step-by-step explanation:

We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure

In the given figure

∵ The dashed line is parallel to the given line up

∴ The angle of the measure 70° and the angle x1 are alternate angles

∵ The alternate angles are equal in measures

∴ x1 = 70°

∵ The dashed line is parallel to the given line down

∴ The angle of the measure 50° and the angle x2 are alternate angles

∵ The alternate angles are equal in measures

∴ x2 = 50°

∵ x = x1 + x2

∴ x = 70 + 50

∴ x = 120°

∴ The value of x is 120°

Answer:

x= 120

Step-by-step explanation:

Alternated angles  are 50 and 70

Angles of a triangle sum 180

Answer:

3 1/3 feets

Step-by-step explanation:

Given that:

Height of aquarium = 1 3/4 feets

Area of aquarium = 5 5/6 ft²

The length of aquarium = x

Aquarium is shaped in the form of a rectangle :

Area of a rectangle = Length * width

5 5/6 = x * 1 3/4

35/6 = 7x/4

Cross multiply :

7x * 6 = 35 * 4

42x = 140

x = 140 / 42

x = 3 14/42

x = 3 1/3 feets

Hence, Length of the back of aquarium is 3 1/3 feets

Answer:

150

Step-by-step explanation:

z=5

x=9

y=3

plug the numbers into a calculator

(9-3)=6

5^2=25

25*6=150

Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.

Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.

To avoid the confusion of having too many sets of parenthses,

let's change the parenthses in the original problem to brackets.

Now let's substitute using parenthses.

So we have (5)² · [(9) - (3)].

Since the parenthses were in the original problem were replaced

by brackets and parenthses come first in your order of operations,

in our problem the brackets are going to come first.

So first simplify 9 - 3 which is 6.

So we have (5)² [(6)].

Exponents come next so we square the 5 to get 25

and that gives us (25) [(6)] which is 150.

Answer: $65

Step-by-step explanation:

The store is having a 20% off sale.

Mai buys an item and saves $13.

This means that $13 is 20% of the price of the item that Mai bought.

Assume the original price is x. Expression is:

x * 20% = 13

x = 13/20%

x = $65

Answer:

Step-by-step explanation:

Answer:

2x + 19.

Step-by-step explanation:

The reasoning behind this is that one must find the disparity between the first and second expressions - 9x+14 and 7x-5.  To do this, one subtracts 7x-5 from 9x+14.  Set this up as though it were a normal subtraction problem - 9x+14 over 7x-5 with the little subtraction symbol to the left.  When subtracting the negative five from fourteen, one adds the five to the fourteen due to the fact that the five was already negative and as such the negatives cancel out.  The 7x is simply subtracted from the 9x, resulting in 2x.  This leads to 2x + 19.

Given:

The graph of a line.

To find:

The y-intercept of the line.

Solution:

y-intercept of a line is the point at which the line intersect the y-axis.

We have, graph of the line.

From the given graph it is clear that the line intersect the y-axis at (0,4).

So, y-intercept is at point (0,4).

y-intercept = 4

Therefore, the y-intercept is 4.

Answer:

The answer is "descriptive statistics".

Step-by-step explanation:

Descriptive statistics are short descriptive factors that add up a production set, that can be either a reflection of a whole or a sample population. It is broken down into cumulative frequency measurements and variance measurements. The study uses descriptive statistics to explain the profile of the respondents. People give simple summaries about the sample as well as the actions.

The area of triangle WXY with altitude YZ is: 8 square units.

Area = 1/2(base × height)

Altitude = height.

Given:

Base = WX = distance between W(2, −1) and X(6, 3):

Using distance formula, [tex]WX = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]:

[tex]WX = \sqrt{(3 - (-1))^2 + (6 - 2)^2}\\\\\mathbf{WX = 5.7 $ units}[/tex]

Altitude/height = YZ = distance between Y(7, 0), and Z(5, 2):

[tex]YZ = \sqrt{(0 - 2)^2 + (7 - 5)^2}\\\\\mathbf{YZ = 2.8 $ units}[/tex]

Area of triangle WXY = 1/2(WX × YZ)

Area of triangle WXY = 1/2(5.7 × 2.8) = 7.98

Area = 8 square units.

Answer:8

Answer:

2/11

Step-by-step explanation:

Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"

4 2/5 + k = -3 2/11

I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.

4 2/5 + k = -3 -2/11

k = - 3 - 4 - 2/5 - 2/11

k= - 7 -2/5 -2/11

Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.

k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)

k = - 385/55 - 22/55 -10/55

k = - (385 +22+10)/55

k = - 417/55

Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.

btw correct me if i am wrong

Answer:

[tex] k = - 1 \frac{12}{55} [/tex]

Step-by-step explanation:

[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]
