6 workers can build a wall in 30 days. If after 6 days 3 more workers join, find the number of days to build the same wall?
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
How to use inverse proportionality to determine building time of a wallIn 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]

To solve this equation for x, we must get x by itself. How would we do this?
X + 4 = 7
A. Add 4 to both sides.
B.Subtract 4 from both sides.
Answer:
B
Step-by-step explanation:
If you were to add 4 to both sides, you would have X + 8 = 11
But when you subract, you get X = 7-4, X = 3.

Because of the pitch of the attic's roof, a bookcase that is 5 feet high must be place
as shown. What is the measure of the angle formed by the roof and the floor of the attic
The measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
Right angle triangle
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°

The tree diagram below shows all of the possible outcomes for flipping three coins.
A tree diagram has outcomes (H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T).
What is the probability that at least two of the coins will be tails?
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.

8. Higher Order Thinking Colby's dog gave birth to 6 puppies. Each puppy in the litter now has a mass of about 3 kilograms. About how much is the mass of the litter of puppies in kilograms? In grams? Remember: 1,000 grams = 1 kilogram.
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:
13 and three-fourths inches
Step-by-step explanation:
The map distance can be found using a proportion with the map scale.
__
map distance / (1100 mi) = (1 in) / (80 mi)
map distance = (1100×1)/80 in = 13 3/4 in . . . multiply by 1100 mi; cancel mi
The trip will be about 13 3/4 inches on the map.

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]

120 - 4.5x = 45 + 0.5x
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

Without drawing the graph, find the coordinates of its intersection with the
x - and y -axes.
y = −2.4x +9.6
The intersection with the x − axis is the point with coordinates ( _,_ ).
The intersection with the y − axis is the point with coordinates(_,_)
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)
