Answer:

x = -1.8

Step-by-step explanation:

Given equation:

[tex]-\dfrac{2}{9} x = \dfrac{2}{5}[/tex]

Part I: Cancel the numerators in the equation (a/d = a/f ⇔ 1/d = 1/f)

[tex]\implies -\dfrac{2}{9} x = \dfrac{2}{5}[/tex]

[tex]\implies -\dfrac{1}{9} x = \dfrac{1}{5}[/tex]

Part II: Use cross multiplication (a/b = c/d ⇔ a × d = b × c) and simplify:

[tex]\implies -\dfrac{1}{9} x = \dfrac{1}{5}[/tex]

[tex]\implies -({x \times 5) = {1 \times 9}[/tex]

[tex]\implies -5x = 9[/tex]

Part III: Divide -5 to both sides of the equation:

[tex]\implies\dfrac{-5x }{-5} = \dfrac{9}{-5}[/tex]

[tex]\implies \boxed{x= \dfrac{9}{-5} = \dfrac{-9}{5} = -1.8}[/tex]

Therefore, the solution is [tex]x = -1.8[/tex].

Answer:

[tex] x = -\dfrac{9}{5} [/tex]

Step-by-step explanation:

[tex] -\dfrac{2}{9}x = \dfrac{2}{5} [/tex]

Multiply both sides by the reciprocal of -2/9 which is -9/2.

[tex] -\dfrac{9}{2} \times (-\dfrac{2}{9})x = -\dfrac{9}{2} \times \dfrac{2}{5} [/tex]

[tex] x = -\dfrac{18}{10} [/tex]

[tex] x = -\dfrac{9}{5} [/tex]

Answer: [tex]75mm^2[/tex]

Step-by-step explanation:

The formula for the area of a paralellogram is:

bh=a

Where

b is the base (15 for this)

h is the height (5 for this)

and a is the area

Let's sub our values into the formula

[tex]bh=a\\(15)(5)=a[/tex]

Now solve

[tex](15)(5)=a\\75=a[/tex]

164

the unknown angle x.

angle at a point= 360°

x= 360 - ( 164 + 90) (because that's a right angle)

x= 360 - 254

x= 106°

Answer:

nancy: $800, beverly: $1200, todd: $1600

Step-by-step explanation:

finding the portion of one part of the ratio:

3600 ÷ 9 = 400 (9 came from 2 + 3 + 4 in the ratio)

Nancy: 2 x 400 = $800

Beverly: 3 x 400 = $1200

Todd: 4 x 400 = $1600

checking the answer:

1600 + 1200 + 800 = 3600

Step-by-step explanation:

[tex]distance = 41km[/tex]

[tex]time = 35min = \frac{35}{60} hr[/tex]

[tex]speed = \frac{distance}{time} [/tex]

[tex]speed = \frac{41}{ \frac{35}{60} } [/tex]

[tex]speed = \frac{41 \times 60}{35} [/tex]

Answer:

24 [tex]m^{3}[/tex]

Step-by-step explanation:

Volume=l*b*h

as tank is half full so height of water will be 4m

and Voulme will be,

V=3*2*4=24 [tex]m^{3}[/tex]

while capacity of tank is,

V=3*2*8=48  [tex]m^{3}[/tex]

The volume of water in the tank, when it is half full, is 24 cubic meters.

Volume in mathematics and physics refers to how much three-dimensional space is occupied by a substance or an object. It is a measurement of the overall volume of space contained inside a three-dimensional object's limits.

The volume of the rectangular tank is given by the formula:

V = l x b x h

where l is the length, b is the breadth, and h is the height of the tank.

Substituting the given values, we get:

V = 3m x 2m x 8m = 48 cubic meters

If the tank is half full, then the volume of water in the tank is:

Vw = (1/2) * V = (1/2) x 48 = 24 cubic meters

Therefore, the volume of water in the tank when it is half full is 24 cubic meters.

Answer:

[B] 12°

Step-by-step explanation:

Given:

Triangle ABC is a right triangle, and m∠ C is 78°.

Solution:

Knowing that Triangle = 180 degree

Square in a right angle = 90° angle.

Thus,

78+90 =168

180-168 is 12

Hence, the answer is [B] 12 degree

The sequence that maps ΔABC to ΔDEF are represented by three transformations: a horizontal and vertical translation and a counterclockwise rotation.

According to Euclidean geometry, a transformation is rigid if and only if Euclidean distances are conserved for every point of the figure. It is to be noticed that there is more than one manner to obtain the resulting figure.

After a careful inspection both on the statement and on the figure, we conclude that the following sequence of transformations:

Scale factor of 3

Answer:

The answer would be four dresses.

Step-by-step explanation:

Step 1. Do 16 divided by 3.67
Step 2. Get the answer of 4.53...
Step 3. Round down because it's the number of whole dresses
Step 4. Get the answer of 4.
Hope this helps! Btw, I don't need Brainliest if the other person wants it.

Answer:

They can make 4 dresses

Step-by-step explanation:

Since it is 3.6667 yards per dress, and the amount they have is 16 yards, divide the amount they have by number of yards per dress to get slightly over 4. Since you can't make a percent of a dress, the answer would be 4.

By finding the scale factor as a quotient of the two given widths, we will see that the new height is 7.7 in

We assume that the height and the width are reduced by the same scale factor.

Such that the scale factor is given by the quotient between the new width and the original width, so we have:

k = 5.4in/32.7in = 0.1651

Then the new height will be the original height times the above number, which gives:

H =  0.1651*46.5 in = 7.7 in

We conclude that the new height of the painting is 7.7 inches.

Answer:

The number is 8.

Step-by-step explanation:

Rewrite the word problem as an equation.

The sum of (we will be adding.), half of a number (we can use x, this will be written as x/2.) and double the number (this will be written as 2x) is 20.

To find the number, solve the equation.

x/2 + 2x = 20

Multiply both sides by 2.

x + 4x = 40

Combine terms.

5x = 40

Divide both sides.

x = 8.
