Answer:

There is 39 mg of vitamins are there in the drink.

Step-by-step explanation:

Given:

A new healthy Drink has 130% of the recommended daily allowance(RDA).

Also RDA for Vitamin = 30 mg

We need to find how many milligrams of the vitamin are in the drink

Let x be number of milligrams of vitamin in the drink.

we can find number of milligrams of vitamin in the drink by multiplying Total percent of RDA with RDA for the vitamin and then divide by 100

x= \frac{130}{100}\times30= 39 \ mg

Hence there is 39 milligrams of vitamin in the drink.

<h3>1.</h3>

The picture shows 5 groups of 3 bars. Each bar represents 1/10. We take the picture to mean that ...

... (15/10) / 5 = 3/10

In decimal:

... 1.5 / 5 = 0.3

<h3>2.</h3>

The picture shows 3 groups of 2 bars. Each bar represents 1/10. We take the picture to mean that ...

... (6/10) / 3 = 2/10

In decimal:

... 0.6 / 3 = 0.2

<h3>3.</h3>

The picture shows 4 groups, each consisting of 1 large square, 1 bar, and 4 small squares. We take the picture to mean that ...

... (4 + 4/10 + 16/100) / 4 = 1 + 1/10 + 4/100

In decimal:

... 4.56 / 4 = 1.14

Please note that 16/100 is equivalent to 1/10 + 6/100. In order to do the division, one of the 1/10 bars needed to be changed into 10 small squares, 10/100.

<h3>4.</h3>

The picture shows 3 groups, each consisting of 1 large square, 3 bars, and 2 small squares. We take the picture to mean that ...

... (3 + 9/10 +6/100) / 3 = 1 +3/10 + 2/100

In decimal:

... 3.96 / 3 = 1.32

Someone help :(( thank youuuu so much if u do
VMariaS [17]

Answer:

-10

Step-by-step explanation:

The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.

in a random sample of 45 endangered species, 12 are categorized as vulnerable, 11 are categorized as endangered, and 22 are cate
horrorfan [7]

The probability that the randomly selected sample is vulnerable or critically endangered is equal to 0.76

The probability can be determined using the following formula;

probability = number of desired events or outcomes ÷ total number of events or outcomes

The total is known to be 45, the favorable or desired outcomes can be calculated as follows;

number of desired outcomes = number of vulnerable species + number of critically endangered species

number of desired outcomes = 12 + 22

number of desired outcomes = 34

Now we calculate the probability by using the above formula;

probability = 34 ÷ 45

probability = 0.76

Therefore, 0.76 is the probability that the randomly selected species is vulnerable or critically endangered.
