Which ratio is the simplest form of ? A 2:1 B 21:14 C 3:2 D 2:3

Answer:y=7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

For the first ratio we can simplifiy it by divide the two numbers by 4

8:4 = 2

20: 4 = 5

2 sneakers to 5 sandals

For the second ratio we can simplify it by dividing the two numbers by 2

4 : 2 = 2

10 : 2 = 5

2 sneakers to 5 sandals

we have found that the two ration are equivalent

Answer: 2,480 grams of sand

Step-by-step explanation:

There are 31 days in July.

Minh sweeps up 80 grams every day in July so at the end of July, Minh should have:

= Number of days * Sand per day

= 31 * 80

= 2,480 grams of sand

Answer:

y = -2/6 x + 2

Step-by-step explanation:

the equation will be an the y=mx+b form. therefore we know the b will be a postive 2 because thatd where it lands on the y axis and the m is the slope which is rise over run which is a negative 2/6. therefore the equation is y = -2/6x + 2

Answer:

[tex] \tan( \alpha ) = \frac{ \sqrt{1 - { \cos( \alpha ) }^{2} } }{ \cos( \alpha ) } = \: \frac{ \sqrt{0.36} }{0.8} = \frac{0.6}{0.8} [/tex]

Answer:

The appropriate answer is "-5.8". A further solution is explained below.

Step-by-step explanation:

The given integers series is:

[tex]-12,-4,-11,-6,4[/tex]

As we know,

⇒  [tex]Mean=\frac{Sum \ of \ All \ Data \ Points}{Number \ of \ Data \ points}[/tex]

On substituting the values, we get

⇒             [tex]=\frac{(-12)+(-4)+(-11)+(-6)+4}{5}[/tex]

⇒             [tex]=\frac{-29}{5}[/tex]

⇒             [tex]=-5.8[/tex]

Answer:

x=40

Step-by-step explanation:

100+2x=180

80=2x

x=40

Answer:

40°, because 180 minus 100 is 80, then divided 80 by 2 (because there is two 2's) and you get 40

Answer: I have no idea What u just said..

Step-by-step explanation:

Answer:

$1600

Step-by-step explanation:

just multiply$8 by 200 and I think $1600 is the answer

The maximum amount, in dollars, of profit Michelle, can earn from the sale of her necklaces is $1,450.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The rent that Michelle pays for the booth at the craft fair is $150. Also, it is mentioned that the selling price of a single necklace is $8, while the number of necklaces that Michelle sells is 200.

The total revenue that Michelle will be able to make from 200 necklaces will be,

The total revenue = $8 × 200 = $1,600

Since profit is the difference between the total revenue and the expenses, therefore, the total profit of the organization can be written as,

Total Profit = $1,600 - $150 = $1,450

Hence, the maximum amount, in dollars, of profit Michelle can earn from the sale of her necklaces is $1,450.

I have attached the complete question.

Answer:

Mean; μ = 1.648

Standard deviation;σ = 0.8610

Step-by-step explanation:

From the image attached, we can see that the probabilities given under the p(x) column are;

0.091

0.334

0.408

0.166

Let's find out if these values give a probability distribution.

ΣP(x) = 0.091 + 0.334 + 0.408 + 0.166

ΣP(x) ≈ 1

Their sum is approximately 1 and they are all between 0 and 1. Thus, it is a probability distribution.

Mean is found by;

μ = ΣxP(x)

From the table attached, x = 0, 1, 2, 3

Thus;

μ = (0 × 0.091) + (1 × 0.334) + (2 × 0.408) + (3 × 0.166)

μ = 1.648

Standard deviation is given by;

σ = √[Σ(x - μ)²•P(x)]

σ = √[((0 - 1.648)² × 0.091) + ((1 - 1.648)² × 0.334) + (2 - 1.648)² × 0.408) + ((3 - 1.648)² × 0.166)]

σ = 0.8610

Answer:

-Area of square = 144 yd²

-Area of semi circle = 56.5 yd² (rounded to nearest 10th)

Step-by-step explanation:

Area of square = 12 × 12

= 144 yd²

r of semi circle= 12÷2= 6yd

Area of semi circle

[tex] = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {6}^{2} \\ = \frac{1}{2} \times \pi \times 36 \\ = 18\pi [/tex]

= 56.54866.....
