Mikel has $20 to spend at the aquarium.

The aquarium charges a $10 admission fee.
The aquarium also has special exhibits that cost $4.00 each to view
Which equation can be used to determine the amount of money, y, that Mikel has left if he views x exhibits?
A y=4x−10
B y=10x−4
C y=10−4x
D y=4−10x

Answer:

640cm³

Step-by-step explanation:

Length SF = ×2

Volume SF = ×2³ = ×8

Volume of B = 8 × 80 = 640cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Volume is a measurement of three-dimensional space that is utilized. It is frequently mathematically quantified using SI-derived units or different imperial or US traditional units. The concept of length is linked to the notion of capacity.

The diagram shows two similar solids, A and B. Solid A has a volume of 80 cm³.

The scale factor is given as,

Scale factor = 8 / 4

Scale factor = 2

The scale factor of the volume is given as,

⇒ 2³

⇒ 8

Then the volume of the solid B will be given as,

Volume of B = 8 x 80

Volume of B = 640 cm³

The volume of the scale factor is 8. Then the volume of the solid B will be 640 cm³.

Answer:

3.3 units²

Step-by-step explanation:

Hi there!

[tex]\frac{Angle(sector)}{360} = \frac{Area (sector)}{Area (circle)}[/tex]

Angle of the sector: 15 degrees

Area of the sector: solving for

Area of the circle: ?

1) Determine the area of the circle

[tex]A=\pi r^2[/tex] where r is the radius

Plug in the radius (5)

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

Therefore, the area of the circle is 25π units².

2) Plug all information into sector formula

[tex]\frac{Angle(sector)}{360} = \frac{Area (sector)}{Area (circle)}\\\frac{15}{360} = \frac{Area (sector)}{25\pi }[/tex]

Multiply both sides by 25π

[tex]\frac{15}{360} *25\pi = Area(sector)\\\frac{15}{360} *25\pi = Area(sector)\\3.3=Area(sector)[/tex]

Therefore, the area of the sector is approximately 3.3 units².

Answer:

  a) (x < -3) ∪ (-1 < x)

  b) all real numbers

  c) x ≤ 1

  d) no solution

Step-by-step explanation:

An absolute value inequality of the form |f(x)| ? a resolves to two inequalities:

  ±f(x) ? a

where ? is some comparison symbol.

__

a) |x +2| > 1

resolves to the inequalities ...

  x + 2 > 1   ⇒   x > -1

and the other inequality this resolves to is ...

  -(x +2) > 1

  -x -2 > 1

  -x > 3

  x < -3

Then the solution is the union of the disjoint solution spaces:

  (x < -3) ∪ (-1 < x)

__

b) |2(x -1)| ≥ 0

  2(x -1) ≥ 0   ⇒   x ≥ 1

and the other inequality this resolves to is ...

  -2(x -1) ≥ 0

  x -1 ≤ 0 . . . . . divide by -2

  x ≤ 1

The union of these solutions is ...

  x ∈ all real numbers

__

c) 9x -4 ≤ 6 -x

  10x ≤ 10 . . . . . . add x+4 to both sides

  x ≤ 1 . . . . . . . . . divide by 10

__

d) No solution. (An absolute value cannot be negative.)

__

The attachment shows the solutions plotted against a number line.

Additional comment

When the inequality is of the form ...

  |f(x)| < a

it can be written as the compound inequality ...

  -a < f(x) < a

If the comparison is > instead of <, using the same "expansion" results in an inconsistency:

  -a > f(x) > a . . . . . . never true for a > 0

If you ignore that technicality (which your teacher may not understand), you can do the solution in the same way you would for the other inequality symbol(s). Just remember the result should be the union of the two disjoint solution spaces.

Using (a) as an example:

  -1 > x+2 > 1 . . . . . to solve this, we subtract 2 everywhere

 -3 > x > -1   ⇒   the solution is (-3>x) ∪ (x>-1)

Answer:

Around 720.

Step-by-step explanation:

Answer:

DR = 10 units

AR = 8.66 units

Step-by-step explanation:

By applying sine rule in the given right triangle,

sin(∠R) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(30°) = [tex]\frac{AD}{DR}[/tex]

[tex]\frac{1}{2}=\frac{5}{DR}[/tex]

DR = 10 units

By applying tangent rule in the given triangle,

tan(∠R) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]tan(30^0)=\frac{AD}{AR}[/tex]

[tex]\frac{1}{\sqrt{3}}=\frac{5}{AR}[/tex]

AR = 5√3

AR = 8.66 units

Answer:

Your right the answer is B a=60 , b=120

A ratio of 1:2 just means one value is twice that of the other.

Answer:

B (a=60, b=120)

Step-by-step explanation:

1. m∠AOB = 180°

2. Since the ratio of a to b is 1:2, set the measure of a as x, and the measure of b as 2x.

3. a+b = 180, so x+2x = 180, 3x = 180, x = 60

4. x = a, so if x=60, then a = 60

5. if b=2x, then b = 2a, which is 2*60 = 120

1) A  B  C  D  E  F  G  H -> The probability of spinning a vowel is 2/8.

2) 1 2  3  4  5  6 -> The probability of rolling an even number on a standard dice is 3/6.

3. To find the probability of spinning a vowel and rolling an even number on a standard dice, we just have to multiply both of the probabilities:

2/8 * 3/6 = 6/48.

4. Simplify 6/48 and you get -> 1/8.

Hope that helps!

For question 13 I found the answer by doing 6 ÷ 2 and 6 ÷ 2 = 3 so I know that 4 will be enlarged by 3 so 4 × 3 = 12 so 12 is the answer for 13

For question 14 I found the answer by using 1 of the sides so I did 24 ÷ 16 and 24 ÷ 16 = 1.5 and 1.5 × 12 = 18 so the answer is 18

For question 15 I did the same thing!

25 ÷ 20 = 1.25 and 1.25 × 12 = 15 so 15 is the answer Hope that helps!

Answer:

The probability that the second number is odd is 50%.

Step-by-step explanation:

Given that Malik randomly picked two different numbers from 1 to 9, and the first one was odd, to determine what is the probability that Malik picked a second odd number given that the first number was odd, the following calculation must be performed:

Odd numbers = 1 - 3 - 5 - 7 - 9 = 5 odd numbers

Even numbers = 2 - 4 - 6 - 8 = 4 even numbers

4/8 = 0.5 x 100 = 50%

Therefore, if from 1 to 9 an odd number was obtained, 8 numbers remain, of which 4 are odd. Therefore, the probability that the second number is odd is 50%.

Answer:

The answer for plato is 2/9

Step-by-step explanation:

2/4+1/6=6/12+2/12=8/12

8/12 simplified=2/3

2/3 of the sugar is needed

3/4-2/3=9/12-8/12=1/12

1/12 of the sugar was left
