Answer:

18 kilograms and 18000 grams

Step-by-step explanation:

the answer in kilograms is 18. the reason why is 6 puppies x 3 kilograms per = 18. Next we need to convert 18 kilograms to grams. 1 kilo = 1,000. multiply 18 x 1,000 = 18000 grams. Please let me know if this helped!!

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

10/75=13.333333334 so around 66 people

you can also just divide 500 by 75 then take it times 10 :)

Answer:

at X axis, Y=0 and at Y axis, X=0

accordingly substitute the value in the equation and find coordinates

Answer:

The intersection with the x-axis is the point with coordinates (4, 0)

The intersection with the y-axis is the point with coordinates (0, 9.6)

Step-by-step explanation:

The line intercepts (crosses) the x-axis when y = 0.

Therefore, substitute y = 0 into the equation and solve for x:

⇒ −2.4x + 9.6 = 0

⇒ −2.4x = -9.6

⇒ x = -9.6 ÷ −2.4

⇒ x = 4

So, the intersection with the x-axis is the point with coordinates (4, 0)

The line intercepts (crosses) the y-axis when x = 0.

Therefore, substitute x = 0 into the equation and solve for y:

⇒ y = −2.4(0) + 9.6

⇒ y = 9.6

So, the intersection with the y-axis is the point with coordinates (0, 9.6)

Convert from mixed numbers to improper fractions:

[tex]\sf area=90 \frac{3}{10}=\dfrac{90 \cdot 10+3}{10}=\dfrac{903}{10}[/tex]

[tex]\sf length=10\frac12=\dfrac{10 \cdot 2+1}{2}=\dfrac{21}{2}[/tex]

Area of a rectangle = length x width

⇒ width = area ÷ length

[tex]\sf \implies width=\dfrac{903}{10} \div \dfrac{21}{2}[/tex]

[tex]\sf \implies width=\dfrac{903}{10} \times \dfrac{2}{21}[/tex]

[tex]\sf \implies width=\dfrac{1806}{210}[/tex]

[tex]\sf \implies width=\dfrac{1806 \div 42}{210 \div 42}[/tex]

Answer:

10d or less

Step-by-step explanation:

Joanne would want $50 left, and she has $250. 20 - 50 is 200. 20 goes into 100 5 times.

20 goes into 200 10 times. You just add five. (20, 40, 60, 80, 100)

If she wants at least $50 left, she would have to limit how many Dvd's she buys to 10 or less.

Answer:

Answer:

x = 15

Step-by-step explanation:

You're trying to solve for x by doing two-step equations.

120- 4.5x = 45 + 0.5x

Add 4.5x to both sides and subtract 45 to both sides.

**Note I did 2 things at once to make it easier to look at.

120-45 = 4.5x + 0.5x

75 = 5x

Now divide 75 by 5

x = 15

The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.

In this question we must use the definition of inverse proportionality, in which the number of workers ([tex]n[/tex]), no unit, is inversely proportional to the building time ([tex]t[/tex]), in days.

According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:

[tex]x = 24\,days \times \frac{6}{9}[/tex]

[tex]x = 16\,days[/tex]

In this scenario, the wall can be built in 22 days. [tex]\blacksquare[/tex]

Answer:

1/2

Step-by-step explanation:

Let H = the possible outcomes that include flipping heads

Let T = the possible outcomes that include flipping tails

In order to have an outcome of two coins having tails, that means for each outcome, you must have at least two T's.

Therefore, the possible outcomes are:

(H, T, T)

(T, H, T)

(T, T, H)

(T, T, T)

This is 4 possible outcomes, and since we want to find the probability we find the total number of outcomes and make a fraction.

[tex]4/8 = 1/2[/tex]

There are 8 outcomes, and since 4 work for this scenario, the answer is 1/2.

The measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.

Right angle triangle are triangle that has one of its angles as 90 degrees. The angles formed can be found using trigonometric ratios.

Therefore,

tan x° = opposite / adjacent

tan x° = 5 / 12

tan x° = 0.41666666666

x = tan⁻¹ 0.41666666666

x = 22.6198649482

x = 22.62°

Therefore, the measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
