In this triangle, what is the value of x?

Enter your answer,

rounded to the nearest tenth, in the box.

Answer:

The answer is 3

Step-by-step explanation:

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0).

Typically, we would start with finding the slope of the line. However, notice how the two x-coordinates in the given points are both -3. This means that this is a vertical line, with an undefined slope.

Vertical lines have their equations organized differently: [tex]x=d[/tex] where d is the x-intercept, or the value of x when y is 0.

Because the x-coordinates in all the points a vertical lines passes through are the same, the x-intercept would therefore be -3. Plug this into the equation [tex]x=d[/tex]:

[tex]x=-3[/tex]

I hope this helps!

--Answer--

negative integer

--Explanation--

28 - 45 = -17; the number subtracting is greater than the original number.

Answer:

x = 3; y = 6

Step-by-step explanation:

Using elimination method:

2x + y = 12

+. (the y will cancel out)

3x - y = 3

5x = 15

therefore, x = 15

5

x = 3

substitute x in one of the equations

2(3) + y = 12

6 + y = 12

y = 12 - 6

y = 6

therefore y = 6

Answer: See explanation

Step-by-step explanation:

Let the price per pound of coffee be c

Let the price ce per pound of butter be b.

We can form an equation based on the information given and this will be:

2c + b = 11.25 ....... i

3c + 2b = 18.50 ....... ii

From equation i, b = 11.25 - 2c ..... iii

Put the value of b into equation ii.

3c + 2b = 18.50

3c + 2(11.25 - 2c) = 18.50

3c + 22.50 - 4c = 18.50

-c = 18.50 - 22.50

c = 4.00

A pound of coffee cost $4.00

Since b = 11.25 - 2c .

b = 11.25 - 2(4.00)

b = 11.25 - 8.00

b = 3.25

A pound of butter costs $3.25

Answer:

√d=4×5

√d=20

square both sides

√d²=20²

the square cancels the square root

d=400

Answer:

The other rational number in the operation given is:

Step-by-step explanation:

To obtain the number in the operation given, we're gonna represent the operation:

Where:

Now we are going to solve r to identify its value in numbers:

As you can see, when we operate, the result is 6/5, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:

In this form, we know the result is correct.

Answer:

The answer is "[tex]125 \ in^2[/tex]"

Step-by-step explanation:

There is a base of five on every triangular face and a height of ten in. The field of the formulation

[tex]A = (\frac{1}{2})bh \\\\A = (\frac{1}{2} \times 5\ in \times 10\ in)[/tex]

   [tex]= \frac{50 }{2} \ in^2\\\\=25 \ in^2\\\\[/tex]

The base of the square has a formula area

 [tex]A = s^2 = (5\ in)^2 = 25 \ in^2[/tex]

The total area consists of the sum of the four-face area and the base: [tex]total \ \ area = 4 \times \text{(area of 1 face) + (area of base)}[/tex]

                   [tex]= 4 \times (25\ in^2 ) + 25 \ in^2 \\\\= 125 \ in^2[/tex]

Answer:

Step-by-step explanation:

First, absolute value is always POSITIVE ⇒ the given inequality has No Solution!!

Just to show you how to solve this kind of problems:

1). If (3x + 5) ≥ 0, then 3x + 5 ≤ - 2

3x ≤ - 5 - 2

3x ≤ - 7

x ≤ - [tex]\frac{7}{3}[/tex]

2). If (3x + 5) < 0, then - (3x + 5) ≤ - 2

3x + 5 ≥ 2

3x ≥ - 3

x ≥ - 1

x ∈ ∅

3 (- 15 + 4) = -45 + 12

This is the answer

Step-by-step explanation:

Even numbers less than 50={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48}

Total=24

Multiples of 5={10,20,30,40}

Probability (multiple of 5)=4/24

=1/6

P(between 10 and 30)=12,14,16, 18, 20, 22, 24, 26, 28

Total=9

Probability=9/24

=3/8

Probability is number 12

=1/24

Probability it has square less than 40

=(4,36)

Two numbers

Probability=2/24

=1/12

I know A is one because positives and negitives are oppisite but i dont know if there are more

Step-by-step explanation:

write the one digit in the square of each of the following numbers

a.13

Answer: 46º

Step-by-step explanation:

The Triangle Sum Theorem states that all triangles’ angles add up to a total of 180º. Therefore, to find X, just set up an equation.

70+64+X=180

134+X=180

-134     -134

X=46

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{24}{4x} = 3[/tex]

24 = 3*4x

24 = 12x

24 / 12 = x

2 = x

Answer:

x= 108

Step-by-step explanation:

use the altitude theorem:

altitude ² = projection of side 1* projection of side 2

x² = 144* (225-144)

x² = 144*81

x= √144*81

x= 108

Answer:

The sum of Ade and Shola is 325. Shola is 25 years older than Ade. Find their present ages.

Step-by-step explanation:

Let x be the present age of Ade

Let y be present age of Shola

x + y = 325 means that the sum of their age is 325

y = x + 25 means that the Shola is 25 years older than Ade

Problem statement

The sum of Ade and Shola is 325. Shola is 25 years older than Ade. Find their present ages.

Answer:

[tex]Range=14[/tex]

[tex]\sigma^2 =32.4[/tex]

[tex]\sigma = 5 .7[/tex]

The standard deviation will remain unchanged.

Step-by-step explanation:

Given

[tex]Data: 136, 129, 141, 139, 138, 127[/tex]

Solving (a): The range

This is calculated as:

[tex]Range = Highest - Least[/tex]

Where:

[tex]Highest = 141; Least = 127[/tex]

So:

[tex]Range=141-127[/tex]

[tex]Range=14[/tex]

Solving (b): The variance

First, we calculate the mean

[tex]\bar x = \frac{1}{n} \sum x[/tex]

[tex]\bar x = \frac{1}{6} (136+ 129+ 141+ 139+ 138+ 127)[/tex]

[tex]\bar x = \frac{1}{6} *810[/tex]

[tex]\bar x = 135[/tex]

The variance is calculated as:

[tex]\sigma^2 =\frac{1}{n-1}\sum(x - \bar x)^2[/tex]

So, we have:

[tex]\sigma^2 =\frac{1}{6-1}*[(136 - 135)^2 +(129 - 135)^2 +(141 - 135)^2 +(139 - 135)^2 +(138 - 135)^2 +(127 - 135)^2][/tex]

[tex]\sigma^2 =\frac{1}{5}*[162][/tex]

[tex]\sigma^2 =32.4[/tex]

Solving (c): The standard deviation

This is calculated as:

[tex]\sigma = \sqrt {\sigma^2 }[/tex]

[tex]\sigma = \sqrt {32.4}[/tex]

[tex]\sigma = 5 .7[/tex] --- approximately

Solving (d): With the stated condition, the standard deviation will remain unchanged.

Answer:

160 [tex]cm^{3}[/tex]

Step-by-step explanation:

We know it is square based, so we know that the sides are the same.

Therefore the length is also 4.

4 * 4 * 10

=160

Answer: [tex]\sqrt{30}/5[/tex]

Step-by-step explanation:

You should get this answer because the simpliest form of a radical is that you shouldn't have any radical in the denominator. In order to get rid of the radical sign in the denominator, you have to multiply the numerator and the denominator with the [tex]\sqrt{5}[/tex].

Answer:

3:7 = 42.86% (hope this helps) ;)

Step-by-step explanation:

Ratios are often expressed in the form m:n or m/n. To convert a ratio into the form of a percentage, simply divide m by n and then multiply the result by 100.

Follow the following steps for converting a ratio to a percentage:

Step 1: (Rewrite as fraction)

3:7 = 37 = 0.4286

Step 2: (Multiply the fraction by 100)

0.4286 x 100% = 42.86%

Answer:

nx12=p

Step-by-step explanation:

So every pack has 12 pencils. You multiply the packs of pencils that José bought with how much pencils per pack. Since José bought "n" packs of pencils, the equation is nx12. But the answer is also unknown since we don't know how much packs José bought, so the answer is "p", or the total number of pencils José bought.

Answer:

[tex]V=83.73\ in^3[/tex]

Step-by-step explanation:

The capsule is in the shape of two hemispheres and cylinder.

The volume of the container = volume of two hemispheres + volume of cylinder

The radius of the container, r = 2 in

Height of the cylindrical part, h = 8 in - 4 in = 4 in

So,

[tex]V=2\times \dfrac{2}{3}\pi r^3+\pi r^2 h\\\\=\dfrac{4}{3}\pi r^3+\pi r^2 h\\\\V=\pi r^2 (\dfrac{4}{3}r+h)[/tex]

Put all the values,

[tex]V=3.14\times 2^2 (\dfrac{4}{3}\times 2+4)\\\\V=83.73\ in^3[/tex]

So, the volume of the container is equal to [tex]83.73\ in^3[/tex].
