Answer:

Scientific notation is a way of expressing, and handling, a mathematical expression used to represent a decimal number between 1 and 10 (multiplied by ten), so large numbers can be made with using less digits. An example would be writing 4 x 10³ for 4,000.

Step-by-step explanation:

Note: It is not given that, 1 cm represents 2m

The bench area on an actual basketball court is 9 meters long.

We need to find how long should the bench be on the scale drawing. Since 1 cm represents 2m. It means 1 m represents 0.5 cm

9 meters will represent,

[tex]\dfrac{9}{0.5}\ cm\\\\=18\ cm[/tex]

Hence, the bench is 18 cm long.

Answer:

  [tex]-\dfrac{5\sqrt{11}}{11}[/tex]

Step-by-step explanation:

Use the relationship between the various trig functions.

  [tex]\tan{\theta}=\dfrac{\sin{\theta}}{\cos{\theta}}=\dfrac{\left(-\dfrac{5}{6}\right)}{\left(\dfrac{\sqrt{11}}{6}\right)}=-\dfrac{5}{\sqrt{11}}\\\\=-\dfrac{5}{\sqrt{11}}\cdot\dfrac{\sqrt{11}}{\sqrt{11}}=\boxed{-\dfrac{5\sqrt{11}}{11}}[/tex]

Greetings from Brasil...

The coefficient a in a linear function (or even a modular function) implies the slope of the function line. The higher the value of a, the greater the slope of the line. the lower the value of a, the lower the slope of the line

Answer:

800

Step-by-step explanation:

Answer:

Horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).

Step-by-step explanation:

Since A is not 0 then C can not be 0 This is a logical deduction from the given formula Ay = C

The equation of any line is y = ax + b, where a is the incline and b is the intercept between the line and the y- axis.

Ay = C

Divide left and right of the = sign by A and you get:

y = C/A

This is the formula for a horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).

Because it is a horizontal line it has an incline of 0.

So a = 0

y = ax + b

a = 0 and b = C/A

y = 0*x + C/A

y = 0 + C/A

y = C/A

Answer:

10x

Step-by-step explanation:

Answer:

10x

Step-by-step explanation:

5x+5x is just like 5+5. So your answer is 10x.

2*3n  would be the equation.

Answer:

i wanna say its C,D,E,F but i get rational and irrational mixed u0

Answer:

Your answer would equal the same on the other side.

-26-4m=-4m-26

if you minus 26 from both sides youll have -4m on both sides also. So it would equal. So you have an Equaled equation if that makes sense.

Answer: do you mean simplified because if so that is the lowest it will go but in percentage form it is 15.79%

Step-by-step explanation:

Answer: c=7

Step-by-step explanation:

8c = 56  Divide both sides by 8

[tex]\frac{8}{8}c = \frac{56}{8}[/tex]  

c = 7

Answer:

if y is the normal number of sweets then the normal number plus 40 percentage equals 42

y+4y=42

1.4y=42

y=42/1.4=30

Answer: 3/8

Step-by-step explanation:

24 min to 64 min as a fraction is [tex]\frac{24}{64}[/tex]    

Now write the fraction is simplest form  by dividing it by their greatest factor.

The GCF of 24 and 64 is 8  

24/8 = 3

64 /8 = 8    

So the ratio will be 3/8

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{25 \: units}}}}}[/tex]

Step-by-step explanation:

Let M ( 9 , -5 ) be ( x₁ , y₁ ) and N ( - 11 , 10 ) be ( x₂ , y₂ )

Finding the distance between these points

[tex] \boxed{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}[/tex]

[tex] \longrightarrow{ \sf{ \sqrt{ {( - 11 - 9)}^{2} + {(10 - ( - 5))}^{2} } }}[/tex]

[tex] \longrightarrow{ \sf{ \sqrt{ {( - 20)}^{2} + {(10 + 5)}^{2} } }}[/tex]

[tex] \longrightarrow{ \sf{ \sqrt{ {( - 20)}^{2} + {(15)}^{2} } }}[/tex]

[tex] \longrightarrow{ \sf{ \sqrt{400 + 225}}} [/tex]

[tex] \longrightarrow{ \sf{ \sqrt{625}}} [/tex]

[tex] \longrightarrow{ \sf{ \sqrt{ {(25)}^{2} } }}[/tex]

[tex] \longrightarrow{ \sf{25 \: units}}[/tex]

Answer:

y=5x−z

Step-by-step explanation:

Step 1: Multiply both sides by y.

xy−5=yz

Step 2: Add -yz to both sides.

xy−5+−yz=yz+−yz

xy−yz−5=0

Step 3: Add 5 to both sides.

xy−yz−5+5=0+5

xy−yz=5

Step 4: Factor out variable y.

y(x−z)=5

Step 5: Divide both sides by x-z.

y(x−z)x−z=5x−z

y=5x−z

Answer:

15 kg, 22.5 kg, 52.5 kg

Step-by-step explanation:

Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x

According to the given information:

[tex]2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg[/tex]

Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg
