does anyone know the answer??

Answer:

It must be proven to be a quadrilateral

Step-by-step explanation:

The question is straightforward, and it requires a direct answer.

A rhombus has four sides and as such it means it is a type of quadrilateral.

So, before a shape is proven to be a rhombus, it has to first be proven to be a quadrilateral.

Answer: Amount of Money Barak  earned last week =$125

Step-by-step explanation:

Amount of money Barak spent= $20

Amount of money spent = 16% of Money earned (X)can be represented as

16%  x  X =20

0.16 x X  =20

X = Money earned last week = 20/ 0.16= $125

Answer:

360 feet.

Step-by-step explanation:

If there are 2 end zones each measuring 10 yards long then that means that both together measure 20 yards long. We add this to the 100 yards of the field and we get a total length of 120 yards. Now we can simply turn this into feet, we know that ...

1 yard = 3 feet

120 yards = x feet

120 * 3 = x

360 feet = x

Finally, we can see that the length of the football field is 360 feet.

Answer:

20 months

Step-by-step explanation:

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months. The overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex].

(a)

As the overcharged amount [tex]w[/tex] varies directly with time [tex]t[/tex],

[tex]w=kt[/tex]

Here, [tex]k[/tex] is a constant.

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every [tex]2[/tex] months.

Put [tex]w=1\,,\,t=2[/tex]

[tex]1=2k\\k=\frac{1}{2}[/tex]

So,

[tex]w=\frac{t}{2}[/tex]

(b)

To find the number of months it will take for Ahmed to be overcharged for 10 liters of water leaked, put [tex]w=10[/tex] in [tex]w=\frac{t}{2}[/tex]

[tex]10=\frac{t}{2}\\\\t=10(2)\\[/tex]

[tex]t=20[/tex] months

Answer:

You may not recognize this...but the base forms a "Pythagorean"  right triangle  with legs  of  6 and 8  cm

The area of a right triangle is  (1/2)  ( product of leg lengths)

So...the area of the base   = (1/2) (6 * 8 ) = (1/2) 48  = 24 cm^2

And the volume of the prism is just the   base area  x  height =   24  x  7  =   192 cm^2

Answer:

23.09 ft

Step-by-step explanation:

tan = [tex]\frac{opposite}{hypotenuse}[/tex]

⇒ tan 13 = [tex]\frac{x}{100}[/tex]

tan of 13 is 0.23086

⇒ 0.23086 = [tex]\frac{x}{100}[/tex]

multiply each side by 100

⇒ 0.23086 x 100 = [tex]\frac{x}{100}[/tex] x 100

solve:

⇒ 23.0868

round to the nearest hundreth:

Answer:

x(x+3)(x-3)

Step-by-step explanation:

Factor out common term x

=x(x^2-9)

Factor x^2-9;

(x+3)(x-3)

=x(x+3)(x-3)

Answer:

x(x + 3)(x - 3)

Step-by-step explanation:

What we're given is a difference of squares multiplied by x.  If we start by factoring x out, we can simply expand the binomial:

x³ - 9x

= x(x² - 9)

= x(x + 3)(x - 3)

Any time you see an expression in the format a² - b², that is called a difference of squares, and can always be expanded out to (a + b)(a - b).  In this case, a is x, and b is 3.

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Given value:

[tex]\to X = 84\\\\\to \mu = 68\\\\\to \sigma= 10\\\\[/tex]

Using formula:

[tex]\bold{Z= \frac{X-\mu}{\sigma}}[/tex]

    [tex]= \frac{84-68}{10}\\\\ = \frac{16}{10}\\\\=1.6[/tex]

Calculating the percent of the sales which is less than or equal to 84 inches:

[tex]\to P(Z \leq 1.6)=0.9452[/tex]

                      [tex]= 0.9452 \times 100\\\\ =94.52\% \approx 95.5\%[/tex]

Calculating the remaining value [tex]100-94.5=5.5\%[/tex] were more than 84 inches.

Answer:1.5

1st box: 0.75

2nd box: 1.5

3rd box: 3

4th box: 28

Step-by-step explanation:

First I got the 4th box. I found out 3.5x2=7, and 7x2=14. So I know the pattern is multiply by 2.

Then I got the 3rd box. I used a proportion. (14x6)/28= 3

Then the 2nd box. I did (3x7)/14=1.5

Lastly, I did the 1st box. (1.5x3.5)/7= 0.75

Answer:

5

Step-by-step explanation:

ratio = 12:20

12/4 = 3

so we do

20/4 = 5

there are 5 boys

Another way, we can write it as a fraction

12/20 = 3/x

12x = 60

x = 5

Answer:

5 boys

Step-by-step explanation:

Write it like this:

3/X=12/20

Then, cross multiply.

3*20=60

X*12=12X

12X=60

Divide both sides by 12

60/12=5

X=5

The unknown number is 5

If there are 3 girls, then there are 5 boys.

Answer:36%=9/25    17/50=34%   0.18=18%     1/4=0.25        Hope that helped:)

Step-by-step explanation:

The solution to the equation is

a) 24 / 25 = 0.96

b) 3/5 = 60 %

c) 9 / 50 = 0.18

26 % = 13 / 50

0.35 = 7 / 20

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

a)

24 / 25

The value of the fraction A = 24/25 is

A = 0.96

Therefore , A = 24/25 = 0.96

b)

3/5

The value of the fraction A = 3/5

Multiply the numerator and denominator by 20 , we get

A = 3/5 x 20/20

A = 60 / 100

A = 60 %

Therefore , A = 3/5 = 60 %

c)

9/50

The value of the fraction A = 9/50

Multiply the numerator and denominator by 2 , we get

A = 3/5 x 2/2

A = 18 / 100

A = 0.18

Therefore , A = 9/50 = 0.18

d)

26 %

The value of the fraction A = 26 %

Convert the percentage A = 26 % into  fraction  , we get

A = 26/100

A = 13 / 50

A = 13/50

Therefore , A = 26 % = 13/50

e)

The value of the fraction A = 0.35

Convert the decimal A = 0.35 to fraction , we get

A = 35 / 100

Divide the numerator and denominator by 5 , we get

A = 7 / 20

Therefore , A = 0.35 = 7 / 20

Hence , the value of the equation A is

a) 24 / 25 = 0.96

b) 3/5 = 60 %

c) 9 / 50 = 0.18

26 % = 13 / 50

0.35 = 7 / 20
