what is the value of x?

Answer:

D. A is the smallest angle

Step-by-step explanation:

Angle A's lines are closest together

Answer:

D. A is the smallest angle

Step-by-step explanation:

To answer this question properly, we need to remember that the sum of the three angles, in a triangle, must result in 180º. Besides, each leg of this triangle is in the opposite direction to the angle of its vertex.

Finally, with the help of a compass we can demonstrate it even better, but in short,  the larger the leg the larger the angle. So, ∠A is the smallest angle since a measures 7 units, then comes ∠B for b measures 10 units and ∠C as the largest angle for c measures 12 units.

Answer:

15.839 rounded to the nearest tenth is 15.8. This is because when we round it to the nearest hundredth it becomes 15.84 and then to the tenth it becomes 15.8, since 4 is less than 5.

Answer:

15.839 redondeado a la décima más cercana es 15.8.

Step-by-step explanation:

Esto se debe a que cuando lo redondeamos a la centésima más cercana se convierte en 15.84 y luego a la décima se convierte en 15.8, ya que 4 es menor que 5.

The sale price of an item with a 33% discount is calculated by subtracting 33% of the list price from the list price itself. The equation for such a calculation is Sale Price = L - (33/100)*L.

The question is dealing with the calculation of a discount on an item's list price. When an item has a list price 'L' and the discount rate is 33%, you would calculate the sale price by subtracting 33% of the list price (L) from the list price itself. It is given by the equation Sale Price = L - (33/100)*L. This calculation will give you the final price that needs to be paid for the item after the application of the discount.

Answer:

x= 8 2/3

Step-by-step explanation:

subtract 1/3 from both sides. 9-1/3 is 8 and 2/3.

To find the population 8 years ago, we can set up an equation and solve for the original population. The population 8 years ago was approximately 37,000 people.

To find the population 8 years ago, we need to calculate the original population before the 35% increase. Let's assume the population 8 years ago was P.

Since the population has increased by 35% over the last 8 years, we can set up the equation: P + 0.35P = 50100

Simplifying the equation, we have: 1.35P = 50100

Divide both sides of the equation by 1.35 to solve for P: P ≈ 37000

Therefore, the population 8 years ago was approximately 37,000 people.

Answer:

(21, 17 )

Step-by-step explanation:

Using the midpoint formula and equating to the coordinates of the midpoint.

Let endpoint 2 have coordinates (x, y ), then

0.5(x - 3) = 9 ( multiply both sides by 2 )

x - 3 = 18 ( add 3 to both sides )

x = 21

and

0.5(y - 5) = 6 ( multiply both sides by 2 )

y - 5 = 12 ( add 5 to both sides )

y = 17

endpoint 2 = (21, 17 )

Answer:

Step-by-step explanation:

Givens

y2 = y/x

y1 = 1

x2 = 1/y

x1 = 1/x

Formula

m = (y2 - y1) / (x2 - x1)

Solution

m = (y/x - 1) / (1/y - 1/x)

m = ( (y - x)/x ) / ((x - y)/xy)

m = (-(x - y) / x) / ( (x - y) / xy)

Invert the denominator and multiply

m = ( - (x - y) / x ) * x*y / (x - y)      Notice x - y cancels.

m = ( - 1 / x ) * (x*y)                        Notice the xs will cancel.

m = ( - 1 / y)                                   There are no xs anywhere. The slope is - 1/y

Answer: Hello there!

If you have the set of points (x1, y1) and (x2, y2), the slope of the segment whit this endpoints is:

[tex]a = \frac{y2 - y1}{x2 - x1}[/tex]

Now, we have the endpoints (1/x, 1) and (1/y, y/x), the slope of this segment is:

[tex]a = \frac{y/x - 1}{1/y - 1/x}[/tex]

Let's simplify it:

[tex]\frac{y/x - 1}{1/y - 1/x} = \frac{(y-x)/x}{(x - y)/x*y} = \frac{\frac{y-x}{x} }{\frac{-(y-x)}{y*x} }= y*\frac{\frac{y-x}{x} }{\frac{-(y-x)}{x} }  = y*(-1) = -y[/tex]

Then the slope of the segment is a = -y, and it does not depend of x

Answer:

32.5 miles

Step-by-step explanation:

The average speed is 65 miles per hour.

You want to keep your commute within 30 minutes, which is HALF AN HOUR.

THus, if you can go 65 miles AN HOUR, in HALF AN HOUR, you can go max, HALF OF THAT!!

So, [tex]\frac{1}{2}*65=32.5[/tex]

Thus, you can go 32.5 miles, max

Answer:

The farthest distance would be 32.5 miles

Step-by-step explanation:

Given,

Speed = 65 miles per hour,

If t represents the time ( in hours ) taken in travelling,

Since, time has to commute down less than 30 minutes,

Also, 1 hour = 60 minutes,

[tex]\implies 1\text{ minute}=\frac{1}{60}\text{ hour}[/tex]

[tex]\implies 30\text{ minutes}=\frac{30}{60}=\frac{1}{2}\text{ hour}[/tex]

Thus,

[tex]t\leq \frac{1}{2}[/tex]

i.e. the highest time taken = 1/2 hours,

We know that,

Distance = speed × time,

∵ Distance ∝ time,

⇒ Distance will farthest for largest time taken,

Hence, the farthest distance = [tex]65\times \frac{1}{2}[/tex] = 32.5 km.

Answer:

the length of CD is 4

the length of DE is 2

the ratio of CD to DE is 2:1

Step-by-step explanation:

The length of segment CD is 4 units and segment DE is 2 units. The ratio of CD to DE is 2:1.

To solve this problem, remember that points on a number line correspond to numbers and the lengths between the points correspond to the differences between these numbers.

The segment CD stretches from 0 to 4, hence the length of CD is 4 units.

The segment DE stretches from 2 to 0, hence the length of DE is 2 units.

However, since length cannot be negative, we take the absolute value of -2, which gives DE = 2 units.

Now, to find the ratio of CD to DE, we simply divide the length of CD by the length of DE.

The ratio of CD to DE can be found by dividing the length of CD by the length of DE. So, the ratio is 4/2 = 2.

Answer:

The distance between R and R' is 3 units ⇒ 1st answer

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same

shape as the original, but in a different size.

If the image is larger than the original figure then dilation is called an

enlargement.

If the image is smaller than the original figure then the dilation

is called a reduction.

The image of a line by dilation parallel to the original line if the original

line not passes through the center of dilation.

Line segment QR is dilated to create line segment Q'R'

∴ QR is parallel to Q'R'

The factor of dilation is 1.5

∴ The length of Q'R' is 1.5 the length of QR

In Δs TRQ and TR'Q'

∵ QR // Q'R'

∴ m∠TRQ = m∠TR'Q'

∴ m∠TQR = m∠TQ'R'

∵ ∠T is common in the two triangles

∴ ΔTRQ is similar to ΔTR'Q'

∴ [tex]\frac{TR'}{TR}=\frac{R'Q'}{RQ}[/tex]

∵ [tex]\frac{Q'R'}{QR}=1.5[/tex]

∵ TR' = TR + y

∵ Tr = 6 units

∴ TR' = 6 + y units

∵ [tex]\frac{TR'}{TR}=\frac{6+y}{6}[/tex]

∴ [tex]1.5=\frac{6+y}{6}[/tex]

Multiply both sides by 6

∴ 9 = 6 + y

Subtract 6 from both sides

∴ 3 = y

* The distance between R and R' is 3 units

Let the inexperienced crew do the apartment in x hours.

Therefore it takes the experienced crew x/2 = 0.5x hours to do the same place.

x + 0.5x = 4 hours

1.5x = 4 hours

x  =  4/1.5

x = 2.67 hours.

So the inexperienced crew does the job in 2.67 hours.

The experienced crew can do it 1/2 the time which is 1.335

Total time = 4 hours.

17-2*3-8=3

Step-by-step explanation:

We have given:

17_2_3_8=3 insert + - × or ÷ symbols to make each statement true​?

Solution:

We will insert multiplication sign between 2 and 3 and then subtract all the terms

17-2*3-8=3

We will solve it according to the DMAS rule:

DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction. Without DMAS rule all mathematical equations will come up with different answers.

Lets solve the expression and check whether the L.H.S = R.H.S

17-2*3-8=3

17-6-8=3

11-8=3

3 =3

Be sure to multiply first and then subtract

⇒You can also insert addition sign in place of multiplication. It will give the same answer

Answer:

17 - 2 × 3 - 8 = 3 ⇒ (- , × , -)

Step-by-step explanation:

Lets revise the order of operation

# Multiplication and Division which comes first from left to right

# Addition and Subtraction which comes first from left to right

Lets explain how to solve the problem

17 __ 2 __ 3 __ 8 = 3

We want to use + , - , × or ÷ symbols to make the statement true

Lets try to find the correct operations

∵ The answer is smaller than all the numbers in the statement

∴ There is subtraction

∵ 17 - 2 = 15

∵ 15 - 3 = 12

∵ 12 - 8 = 4 which is not the answer

Then lets multiply 17 , 2 and multiply 3 , 8 and subtract their results

∵ 17 × 2 = 34

∵ 3 × 8 = 24

∵ 34 - 24 = 10 which is not the answer

Then lets multiply 2 , 3 and then subtract the result from 17 and then

subtract 8 from the last result

∵ 2 × 3 = 6

∵ 17 - 6 = 11

∵ 11 - 8 = 3 which is the answer

∴ 17 - 2 × 3 - 8 = 3

∴ The symbols are -  , × ,  -
