Dad bought 2 hammers one cost 18$ and the other cost 28$ more. Whta is his total bill?

Answer:

b x h divided by 2
=4x6 divided by 2
=24 divided by 2
=12

Step-by-step explanation:

Answer is 12 if I follow the formula :)

[tex]\textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\cfrac{sin(B)}{\overline{AC}}=\cfrac{sin(C)}{\overline{AB}}\implies \cfrac{sin(38^o)}{9}=\cfrac{sin(C)}{11}\implies \cfrac{11\cdot sin(38^o)}{9}=sin(C) \\\\\\ sin^{-1}\left[ \cfrac{11\cdot sin(38^o)}{9} \right]=sin^{-1}\left[ sin(C) \right]\implies sin^{-1}\left[ \cfrac{11\cdot sin(38^o)}{9} \right]=\measuredangle C \\\\\\ 48.81^o\approx \measuredangle C~\hspace{10em} therefore\qquad 180-38 - 48.81 ~~\approx ~~\stackrel{\measuredangle A}{93.19^o}[/tex]

Answer:

8x + 2

Step-by-step explanation:

It's really quite simple!

Take not of the equation, 5x + 2 + 3x

As 5x and 3x have the same term, you can add them up together, giving you 8x.

Add the 2 on, and you have your answer!

Answer:

8x+2

Step-by-step explanation:

5x + 3x = 8x and 1+1=2

so the answer is 8x+2

1. make the percent into a decimal

2. subtract the decimal by 1

3. divide the number you just got and the decimal you got from the first step

Answer:

the answer is 42 m2

Step-by-step explanation:

7×6=42

Answer:

Step-by-step explanation:

77 points. 82*4=328 328-72-97-82=77 You can check this by adding 77,72,97, and 82, and divide it by 4

Answer:

[tex]66\frac{2}{3}%[/tex]

Step-by-step explanation:

He has 3 pairs of sneakers:

1 Black

1 Blue

1 White

2 out of 3 are not blue.

This can be written as 2/3

Percentage is a certain number over the denominator of a base ten numeral.

2/3 = [tex]66\frac{2}{3}[/tex]%

Hope this helps :)

Have a great day!

Step-by-step explanation:

[tex] \sin(x - y) + \sin(x + y) = 2 \sin(x) \cos(y) [/tex]

We use the sum and difference identities.

Remeber the sum difference identity is

[tex] \sin(x + y) = \sin(x) \cos(y) + \cos( x ) \sin(y) [/tex]

and

[tex] \sin(x - y) = \sin(x) \cos(y) - \sin(x) \cos(y) [/tex]

So we get

[tex] (\sin(x) \cos(y) - \sin(y) \cos(x) ) + \sin(x) \cos(y) + \sin(y) \cos(x) [/tex]

Combine like Terms.

[tex]2 \sin(x) \cos(y) = 2 \sin(x) \cos(y) [/tex]

We have provided it.

Answer:

if you are asking us then probably a... hmmm -_- 3 yes
3 out of 10

Step-by-step explanation:

Answer: we’ll first to find how “smart” you are, we have to verify the level of unsmartness and see if there is any given number. Since the is no given number we will use x as our unknown number. Then we will subtract 1 from 10, therefore giving us the number 9 that we will use in our equation to determine the level of “smart”.

Now we will put 9 and x together:

9x

Now we will find the next part of our equation which will find by looking at how we got the number 9, which is: 10-1

Now we group the parts of this equation which will be:

9x÷10-1

First we will solve one side of our equation

10-1=9

Then we will insert the solved side of the equation

9x÷9

Now we will divide

9/9x
we are left with 1

x=1

Now we insert our solved number back into our previous equation with 1 replacing x

9⋅1÷10-1

Now after we have solved the equation

The answer is: -0.1 will be your level of “smart”

I think it the first one is

Answer:

[tex](-\infty,-4)\cup(8,\infty)[/tex]

Step-by-step explanation:

All real numbers on its own in interval notation is [tex](-\infty,\infty)[/tex], but if we are to exclude -4 and 8, then we would need two separate intervals joined in union.

Thus, [tex](-\infty,-4)\cup(8,\infty)[/tex] would be the correct notation

Answer:

Common difference:6 3 terms: -15, -9. -3

Step-by-step explanation:

-39, -33, -27, and -21 all have a difference of 6.

4/3 ÷ 5/2

4/3 × 2/5 (by reciprocal)

8/15

Therefore, 8/15 is the correct answer

Answer:

Answer:

[tex]\frac{\sqrt[4]{10xy^3}}{2y}[/tex]

Step-by-step explanation:

I am assuming you want me to rationalize the denominator.

Answer:

X going up by 4s  Y going up by 16s

Step-by-step explanation:

X

-7+4=-3

-3+4=1

1+4=5

And so on...

Y

-28+16=-12

-12+16=4

4+16=20

And so on...

If this is meant for slope then you would use the formula m=y2-y1/x2-x1

You can use -12 to equal y2 and -21 to equal y1

You can use -3 to equal x2 and -7 to equal x1

Now your equation should be...

m=-12-(-21)/-3-(-7)

m=9/4

9 is the rise

4 is the run

the slope is 9/4

Y-intercept for would be...

m=9/4x

57.4 millilitres

We know that the chemist has 332 milliliters of the solution of acid and water, and 17.3% of that solution is acid.

We can then persume that the amount of acid in the solution is equal to 332ml × 17.3%

This is equal to 57.436ml.

Then the question states to round the answer to the nearest tenth.

Rounding 57.436ml to the nearest tenth (.1) will equal to 57.4ml.

Therefore, there are 57.4ml of acid in the solution rounded to the nearest tenth.
