Answer:
3(5q+9)+5q is equal to 4(5q+6)
Step-by-step explanation:
3(5q+9)+5q is equal to 4(5q+6). To show this, first expand the expressions:
3(5q+9)+5q = 15q+27+5q = 20q+27
4(5q+6) = 20q+24

15/7 + h = 37/7
h = 22/7.
choose the correct reasoning for why h=22/7
A. h=22/7 Because 37/7 is 22/7 more than 15/7
B. h=22/7 Because 37/7 is 22/7 less than 15/7
Answer:
Given [tex]\frac{15}{7} + h = \frac{37}{7}[/tex]
When h = [tex]\frac{22}{7}[/tex]
[tex]\frac{15}{7} + \frac{22}{7} = \frac{37}{7}[/tex]
We add 15 and 22 on the left side, because the denominators are equivalent.
15 + 22 = 37, [tex]\frac{37}{7}[/tex] = [tex]\frac{37}{7}[/tex]
So this statement is true.
That means the correct option is A.
Have a wonderful day! :-)
May someboy help my brain. Its just sales tax. Btw the second answer is wrong.
Answer:
$4.94
Step-by-step explanation:
We can first solve this by turning this sales tax percentage into a decimal
[tex]8.6\% = 0.086\%[/tex]
Now that we got that and your first answer of $57.40, we can multiply the two numbers.
[tex]0.086 \times 57.40 = 4.9364[/tex]
That rounds to 4.94

20% of what number is 12
Answer: 12 is 20 % of the number 60
Step-by-step explanation:
Answer:
2.4
Step-by-step explanation:
Re-write 20%
[tex]\frac{20}{100}[/tex]
Since, finding a fraction of a number is also the same as multiplying the fraction with the number, we have:
[tex]\frac{20}{100}[/tex] of 12 = [tex]\frac{20}{100}[/tex] x 12
The answer is:
2.4

Step-by-step explanation:
2(5 x 10) top and bottom rectangles
1(10 x 6) the middle rectangle
2 ((1/2(6 x 4)) the two triangles
Sum of all the areas = 2(5 x 10) + (10 x 6) + 2((1/2(6 x 4))
This matches answer B
Answer:
B
Step-by-step explanation:
The rectangle measurements are 10 in by 5 in, and there are 2 rectangles with that measurement, so the first part is 2(5 × 10). Using the process of elimination, none of the other answer choices have that particular answer, so it's B. Hope this helps! Have a great day! :)
You have 2 different savings accounts. For Account A, the simple interest earned after 9 months is $6.75. For Account B, the simple interest earned after 21 months is $19.25. If the interest rate is 3.6% for Account A and 2.2% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
PLS HELP ME WITH THIS, I DON'T UNDERSTAND THIS!
Answer:
Step-by-step explanation:
Answer: Foremost sum could Be a = $250.09 Principal sum is B = $400. Account B earned you the foremost intrigued the first month The equation for straightforward intrigued is communicated as I = PRT/100 Where P = the central or starting sum of cash invested. R = intrigued rate T = time
On account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years.
On account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
To decide the account that earned more intrigued within the to begin with month we separate the intrigued by the number of months.
$6.94/9 = $0.7711
$13.80/18 = $0.7667
Account B earned you the foremost intrigued the first month since $0.7667 is higher than $0.7711.

Susie made a large pot for her family. The pot Susie used has a capacity of 5 liters. Why could the capacity of the same pot be 5,000 milliliters?
Answer:
Because:
[tex]1 \: liter = 1000 \: milliliters[/tex]
Therefore to change from litres milliliters we multiply with 1000
[tex]5 \times 1000 = 5000[/tex]

There are two triangles satisfying angle BCA = 60 degree, AB = 9 and AC = 10 shown below:
The possible values of BC are a_1 and a_2$, as shown in the picture, with a_1
Answer:
Step-by-step explanation:
So...let's figure a2 first
a2 / sin (45.8) = 9 /sin C
a2 / sin (45.8) = 9 / [ sqrt (3) / 2 ]
a2 =sin (45.8) * 18 / sqrt 3 ≈ 7.45
And in the second case
C = 180 -60 - 105.8 ≈ 14.2°
So....by the Law of Sines again we can find a1 as
a1 / sin (14.2) = 18/sqrt 3
a1= sin (14.2) * 18 /sqrt 3 ≈ 2.55
{a1 , a2} = {2.55 , 7.45}

There's one triangle satisfying angle BCA = 60 degrees, AB = 12 and AC = 10 shown below:
The only possible value of BC is a, as shown above. What is a?
Please don't round your answer. Keep it as a square root.
Answer:
see attached
Step-by-step explanation:
you need to create 2 right angle triangles
one on the left has 60° which makes it a special right angle triangle with the property of the following:
the side that's opposing the 30° angle will be 1/2 of the long side,
the side that's adjacent to the 30° angle will be √3/2 of the long side
once you know these, the rest is easy
Answer:
a = 5 + √69
Step-by-step explanation:
I am just providing another way of solving this. The answer provided by user elzny is absolutely correct and probably easier to understand. He has done a great job.
We can solve for a using the law of cosines which states that given, two sides of a triangle(say a and b) and an included angle (say C), the third side, c can be determined by the relation:
c² = a² + b² -2ab(cosC)
or
a² + b² -2ab(cosC) = c²
If we look at the triangle we see that angle C measures 60° and the two sides that include this angle are of lengths 10 and a. The third side is 12
Plugging in these values into the equation,
10² + a² - 2(10)(a)(cos 60) = 12²
100 + a² -20a(cos 60) = 144
cos 60 = 1/2
So
100 + a² - 20a (1/2) = 144
(100 - 144) + a² - 10a = 0
a² -10a -44 = 0
This is a quadratic equation which can be solved to get two values for a
The solution to this quadratic equation is done using the quadratic formula
[tex]x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }[/tex]
where
a = coefficient of x² = 1 in this problemb = coefficient of x = -10 in this problemc = constant = -44Plugging in these values,
[tex]x = \dfrac{ -(-10) \pm \sqrt{(-10)^2 - 4(1)(-44)}}{ 2(1) }\\\\x = \dfrac{ 10 \pm \sqrt{100 - (-176)}}{ 2 }\\\\x = \dfrac{10}{2} \pm \dfrac{\sqrt{276}}{2}}[/tex]
Factor 276 to get 276 = 4 x 69
[tex]\sqrt{276} = \sqrt{4 \cdot 69} = \sqrt{4} \cdot \sqrt{69} = 2 \sqrt{69}[/tex]
This results in
[tex]x = \dfrac{ 10 }{ 2 } \pm \dfrac{2\sqrt{69}\, }{ 2 }\\\\x = 5 \pm \sqrt{69}\\\\[/tex]
[tex]\sqrt{69}[/tex] is greater than 5 so we take only the positive component which is
[tex]5 + \sqrt{69}[/tex]
Which is the same answer as what elzny provided.
The pro of this methodology:
Direct implementation without splitting the triangle
The con:
You have to solve a quadratic equation which is not fun. But most scientific calculators can do this for you
Thanks!
Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because 60 ➗ 5 = 12. Does Noah’s method always work? Explain why or why not.
Answer:
No, Noah's method does not always work.
Step-by-step explanation:
Let's say we're trying to find 40% of 80 instead of 20% of 60.
If we divide 80 by 5, like Noah says, we get 16, which is not 40% of 80.
The proper solution would be to multiply the number by the percentage converted to a decimal.
In this case, it would be 80 × 0.4, which is 32.
When you try to solve 20% of 60, you can say 60 × 0.2, which also gets 16.
Answer:
No it doesn't
Step-by-step explanation:
His method never works because multiplying by does not give the same result as dividing by 5. AI Recommended Answer: To find 20% of a number, divide the number by 5. For example, 20% of 60 is 12.

To paint a house, a painting company charges a flat rate of $500 for supplies, plus $50 for each of labor.
Answer:
A=$1,500, $3,000
B=Y=50x+500 (explained below)
Step-by-step explanation:
you start with the funtion “y=mx+b”. m is the slope, and b is the y intercept. x is how far right or left the point is and y is how far up or down the point is. Then you plug in the information you know. If they charge $50 for each hour, you plug that into the slope, and plug the $500 into the y intercept because that is the initial price, no matter how long it takes them. After you plug those in, it will look like “y=50x+500”. Then you look at what A is asking, for 20 or 50 hours of labor. On the graph it show you that hours is on the x-axis, so you plug the numbers into the equation. The first one, 20, would look like “50(20)+500”. Then the simple part, you solve it. 50 times 20 is 1,000 and 1,000 plus 500 is 1,500. So if they were to work for 20 hours, it would cost $1,500. You do the same for the second one, looking like “50(50)+500” ending up to 3,000. Those are your answers for A. For B, you need to plot the line. You take the easy one, with x being 0. You plot a dot on the y-axis, at (0,500), then you need to plug a number in for the second one, lets take the first number shown on the x-axis, 10. You plug it into the formula, looking like “y=50(10)+500” ending up at “y=1,000” so you plot another dot at (10,1,000). You then take a straight edge, line up the two dots, and draw your line.
