Answer:

The First One

Step-by-step explanation:

Try to substitute x by zero for example

(the minus will gone by zero)

I hope that it's a clear solution and explanation.

Joseph has a job walking dogs and gets paid per dog. He needs to walk 45 dogs to earn enough money to pay for his soccer team fe

rusak2 [61]

Using proportions, it is found that it will take him 22.5 hours to walk the 45 dogs.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

He walks 3 dogs in 1 hour and 30 minutes, we means that the time in hours it takes for him to walk a dog is:

t = 1.5/3 = 0.5 hours.

Hence the time it will take him to walk 45 dogs is given by:

45 x 0.5 = 22.5 hours.

$124.56 because if you have 63% you change it to a decimal so it is not .63 and you multiply it by 146.16 and then add the 35 you get 124.56

$\huge\text{Hey there!}$

$\mathsf{\dfrac{9}{10}+\dfrac{7}{15}}$

$\large\textsf{FIRST: FIND the LCD (Lowest Common Denominator) then solve}\\\large\textsf{from there!}$

$\large\textsf{If you have calculated it correctly, you should have came up with \underline{\bf 30}}\\\large\textsf{as your LCD (Lowest Common Denominator).}$

$\mathsf{= \dfrac{9\times3}{10\times3}+ \dfrac{7\times2}{15\times2}}$

$\mathsf{9\times3=\bf 27}\\\mathsf{10\times3=\bf 30}\\\\\mathsf{7\times2=\bf 14}\\\mathsf{15\times2=\bf 30}$

$\mathsf{= \dfrac{27}{30}+\dfrac{14}{30}}$

HELP PLEASE WILL MARL BRANIEST IF right

Kaylis [27]

Answer:

A bit of a doosy, but bare with me: f*g*h(x) = $x^2+54x-12x\sqrt{x} -108\sqrt{x} +90$

Step-by-step explanation:

So explaining this is a bit awkward as well, but I can try...So

Starting from g(x) working that backwards into f(x), so...

g(x) = $x-3$

f(x) = $(x^4+9)$

Take your g(x) and plug it into your f(x) into every x you see

f(g(x)) = $(x-3)^4+9$ ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...

Now you still have one more step which you still need to include h(x), so

Remember h(x) = $\sqrt{x}$

Now plug in your h(x) into every x you see from f(g(x)) and it should look like...

$(\sqrt{x} -3)^4 + 9$

Nataliya [291]

With the help of the ratio method, we conclude that 72 grams of sugar should be added.

<h3>What is Ratio Method?</h3>

In the ratio method, we compare two quantities by equating their two ratios; this equation is also referred to as a proportion.
The cross-multiplication method will be used to solve it.

So, 'n=5' will be the number of rings.

'w = 18 grams' will be the weight of each ring.
Total weight: w₀ = n × w = 5 × 18 = 90 grams

Let 's' be silver. Then,

New weight: wₙ = s + 90
Old % of gold: p₀ = 90% = 0.9
New % of gold: pₙ = 50% = 0.5

Now, use the ratio method as follows:

$\frac{w_o}{w_n}=\frac{p_n}{p_o}$
$\frac{90}{s+90}=\frac{0.5}{0.9}$
90 × 0.9 = 0.5 × (s + 90)
81 = 0.5s + 0.5 × 90
81 = 0.5s + 45
81 - 45 = 0.5s
36 = 0.5s
36/0.5 = s
72 = s
So, s = 72

Therefore, with the help of the ratio method, we conclude that 72 grams of sugar should be added.

The correct question is given below:
A jeweler has five rings, each weighing 18 grams, made of alloys of 10% silver and 90% gold. He decides to melt down the rings and add enough silver to reduce the gold content to 50%. How much silver should he add?
