Which answer shows 0.05 written in scientific notation?​

Answer:

5:3

Step-by-step explanation:

40% = 2/5

If the numbers are x and y, then

2/5 x = 2/3 y

Divide both sides by 2/5

x  = (2/3 * 5/2)y

x = 10/6 y

x = 5/3  y

So the required ratio is 5 : 3.

Checking this result:

10% of 5 = 2

2/3 of 3 = 2 also.

Answer:

-8

Step-by-step explanation:

you know, all you have to do in such a case is simply taking the given -2 and put it, where there is "x" in the function expression and then calculate this. if necessary with a calculator.

2×2×x with x=-2 is

2×2×-2 = -8

Answer:

- 8

Step-by-step explanation:

f ( x ) = 2 . 2 x

f ( - 2 )

= 2 . 2 ( - 2 )

= 2 x 2 x ( - 2 )

= - 8

Answer:

[tex]x=55[/tex]

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of [tex]2x+6[/tex] corresponds with the angle marked as [tex]x+9[/tex]. Therefore, its measure must also be [tex]x+9[/tex].

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

[tex]2x+6+x+9=180[/tex]

Combine like terms:

[tex]3x+15=180[/tex]

Subtract 15 from both sides:

[tex]3x=165[/tex]

Divide both sides by 3:

[tex]x=\frac{165}{3}=\boxed{55}[/tex]

Answer:

? ≈ 24°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{17}[/tex] , then

? - [tex]sin^{-1}[/tex] ([tex]\frac{7}{17}[/tex] ) ≈ 24° ( to the nearest degree )

Answer:

[tex]\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}[/tex]

[tex]\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{b}{7a^2c}[/tex]

Express the denominator as [tex]35a^3c^3[/tex]

To do this, we divide[tex]35a^3c^3[/tex] by the denominator

[tex]\frac{35a^3c^3}{7a^2c} = 5ac^2[/tex]

So, the required fraction is:

[tex]\frac{b}{7a^2c} * \frac{5ac^2}{5ac^2}[/tex]

[tex]\frac{5abc^2}{35a^3c^3}[/tex]

Hence:

[tex]\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}[/tex]

Given

[tex]\frac{a}{a - 4}[/tex]

Express the denominator as [tex]16 - a^2[/tex]

Multiply the fraction a+4/a+4

So, we have:

[tex]\frac{a}{a - 4} * \frac{(a + 4)}{(a + 4)}[/tex]

Apply difference of two squares to the denominator

[tex]\frac{a^2 + 4a}{a^2 - 16}[/tex]

Take the additive inverse of the numerator and denominator

[tex]\frac{-(a^2 + 4a)}{-(a^2 - 16)}[/tex]

[tex]\frac{-a^2 - 4a}{16 -a^2}[/tex]

Hence:

[tex]\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}[/tex]

980 miles

Step-by-step explanation:

5 hours =490miles

1 hour =490/5=98miles

10hours = 98×10=980miles

Answer:

First part: 0.35 miles per minute

Second part: 3.5 miles in 10 minutes

Step-by-step explanation:

Think about this as a fraction. Fractions can't be added nor subtracted unless they share the same denominator. So for this case, we have to turn hours into minutes. So 21 mph becomes 21 miles per 60 minutes. Then, we divide 60 from each side to find the speed per minute. 21/60 = 0.35, so the answer to the first part is 0.35 miles per minute.

Using what we got, we can answer the second part of the distance covered in 10 minutes. So, we just multiply 0.35 by 10 which is 3.5 miles covered in 10 minutes.

Answer:

x=5

Step-by-step explanation:

since this is an isosceles triangle, this means that the two base angles are equal. therefore, 8y-7=73°, meaning that y = 10° (although we don't really need to know that since you're just supposed to find x).

the angles of a triangle add up to 180°, so we can add all the angles and set them equal to 180° to find x.

6x+4+73+73=180

6x+150=180

6x=30

x=5

Answer:

40 minutes

Step-by-step explanation:

360/60 = 6 degrees per minute

240/6 = 40 minutes

Answer:

40 minutes / 2400 seconds

Step-by-step explanation:

One full rotation of a circle is 360°

One hour (full rotation of minute hand) is 60 minutes

360° = 60min

Divide both sides by 60

6° = 1min

So every 6° is 1 minute.

240° / 6° = (x minutes) / 1 minute

x = 40 minutes

Alternatively:

1 hour = 60 minutes

1 minute = 60 seconds

So, 1 hour = 60×60 = 3600 seconds

3600 seconds / 360° = 10 sec/°

==> This means that every 1° is 10 seconds on the minute hand

240° × 10 sec/° = 2400 sec

(Divide by 60 for 40 minutes)

Answer:

x = (5/3)

Answer: x = 120

Step-by-step explanation:

Okay so you have three similar right triangles. To find x, you can set up an proportion [tex]\frac{shorter leg}{long leg} = \frac{64}{x} = \frac{x}{225}[/tex]  since similar figures are in proportion. By cross multiplying and finding the square root of x^2, you result in x equaling 120.

Answer:

s=9

d=6

Step-by-step explanation:

s+d=15

3.s+5.d=57

⇒s=9 và  d=6

The sum of A, B, C, and E is 23. Let's set up a system of equations based on the given information: s: number of single-scoop cones

d: number of double-scoop cones

1. The coach bought 15 cones in total:

s + d = 15

2. The cost of a single-scoop cone was $3 and the cost of a double-scoop cone was $5, and the total payment was $57:

3s + 5d = 57

Now, let's find the values of s and d by solving the system of equations.

First, we can use the first equation to solve for s in terms of d:

s = 15 - d

Now, substitute this value of s into the second equation:

3(15 - d) + 5d = 57

Now, solve for d:

45 - 3d + 5d = 57

2d = 57 - 45

2d = 12

d = 6

Now that we have the value of d, we can find the value of s using the first equation:

s = 15 - d

s = 15 - 6

s = 9

So, the number of single-scoop cones (s) is 9, and the number of double-scoop cones (d) is 6.

Now, let's find the sum of A, B, C, and E:

A: The number of single-scoop cones (s) is 9.

B: The number of double-scoop cones (d) is 6.

C: The cost of a single-scoop cone is $3.

E: The cost of a double-scoop cone is $5.

A + B + C + E = 9 + 6 + 3 + 5 = 23

So, the sum of A, B, C, and E is 23.
