12 and 5 inches since squaring them would equal 144+25, which is 169, and ✓169=13. the two legs have to equal the hypotenuse when combined to be a right triangle.
Please give me the correct answer
Answer: 3.75
Step-by-step explanation:
[tex]b = 5\\c=6.25\\a^{2} + b^{2} = c^{2} \\a^{2} +5^{2} = 6.25^{2} \\a^{2} + 25 = 39.0625\\a^{2} = 14.0625\\\sqrt{a^{2}} =\sqrt{14.0625} \\a = 3.75[/tex]

(b)Newton has bought 12 dozen copies in Rs 4320. His expenditure to bring the copies
to his shop is Rs. 288. How much profit does he make in one copy after selling all
copies in Rs. 5760? Also how much profit in percent did he get in the business of
copy? Find it.
Plz answer
Answer:
He made a profit of 40-32 = Rs 8 per copy.
He got a 25% profit in the business of copies
Step-by-step explanation:
Newton buys and sells copies in his business. He bought 12 dozen = 12*12=144 copies in Rs 4320.
He also has Rs 288 in expenses to bring the copies to his shop, thus the total cost is 4320+288=4608.
Each copy finally cost 4608/144 = Rs 32.
He sold all copies for Rs 5760, at 5760/144= Rs 40 each.
Therefore, he made a profit of 40-32 = Rs 8 per copy.
The total profit in his business of copies was 5760 - 4608= 1152
This is a percentage of:
[tex]\frac{1152}{4608}*100 = 25\%[/tex]

Kathy needs money for a trip to Europe if she has US$300 in the bank but wants to withdraw half of it In British pounds and half of it into euros how many more euros and times with Havasu 1 pound equals 1.6 for US deep and one euro equals 1.3 to USD and round to the nearest whole
Answer: She has 21.63 more euros than pounds and has 1.23 times more euros than pounds.
Step-by-step explanation:
She has US$300, and she will withdraw half of it on pounds, and half of it in euros.
(half of US$300 is US$150)
We know that:
1 pound = US$1.6
(1 pound/US$1.6) = 1
Then US$150 = US$150*(1 pound/US$1.6) = (150/1.6) pounds = 93.75 pounds.
And we also know that:
1 euro = US$ 1.3
then:
(1 euro/US$ 1.3) = 1
This means that:
US$150 = US$150*(1 euro/US$ 1.3) = (150/1.3) euros = 115.38 euros.
This means that:
115.38 - 93.75 = 21.63
This means that she has 21.63 more euros than pounds.
and:
115.38/93.75 = 1.23
She has 1.23 times more euros than pounds.

Step-by-step explanation:
3(4−7)=27
How do I solve this
Answer:
x = 4
Step-by-step explanation:
3(4x - 7) = 27
distribute the 3
(3 * 4x) + (3 * -7) = 27
12x + (3 * -7) = 27
12x - 21 = 27
add 21 to both sides of the equations
12x - 21 + 21 = 27 + 21
12x = 27 + 21
12x = 48
divide both sides by 12
12x/12 = 48/12
x = 48/12
x = 4/1
x = 4

Find the missing angle. Find X
Answer:
I don’t know 160.
Step-by-step explanation:
20 plus 160 equals 180.
The correct answer is 20° since x and 20° are vertically opposite angles.
In other words, the value of x is equal to 20°.
Vertically opposite angles are formed by the intersection of two lines. They are opposite each other and have equal measures. When two lines intersect, the vertically opposite angles are formed on the opposite sides of the intersection point. These angles are also known as vertical angles or opposite angles. The property of vertical angles states that their measures are equal. This means that if one angle measures x degrees, the other vertical angle will also measure x degrees. Vertically opposite angles are important in geometry and are often used to prove theorems and solve geometric problems.
Therefore, the correct answer is 20° since x and 20° are vertically opposite angles.In other words, the value of x is equal to 20°.

Answer:
[tex]\frac{1}{2\sqrt{5} }[/tex]
Step-by-step explanation:
Let, [tex]\text{sin}^{-1}(\frac{x}{6})[/tex] = y
sin(y) = [tex]\frac{x}{6}[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\frac{d}{dx}(\frac{x}{6})[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\frac{1}{6}[/tex]
[tex]\frac{d}{dx}\text{sin(y)}=\text{cos}(y)\frac{dy}{dx}[/tex] ---------(1)
[tex]\frac{1}{6}=\text{cos}(y)\frac{dy}{dx}[/tex]
[tex]\frac{dy}{dx}=\frac{1}{6\text{cos(y)}}[/tex]
cos(y) = [tex]\sqrt{1-\text{sin}^{2}(y) }[/tex]
= [tex]\sqrt{1-(\frac{x}{6})^2}[/tex]

Therefore, from equation (1),

You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 1 parts cream and 3 part blue. How much blue paint will you need to mix with 4 litres of red?. Single line text.
Answer:
6 litres of blue color should be mixed.
Step-by-step explanation:
To get the paint color as per my wish, paint of different colors are mixed in the ratio = Red : Cream : Blue
= 2 : 1 : 3
In this mixture, ratio of red and blue color = 3 : 2
This ratio will be constant for any amount of mixture.
Therefore, [tex]\frac{\text{Amount of Blue color}}{\text{Amount of red color}}=\frac{3}{2}[/tex]
[tex]\frac{b}{4}=\frac{3}{2}[/tex]
b = [tex]\frac{3}{2}\times 4[/tex]
b = 6 litres
Therefore, 6 litres of blue color should be mixed with the 4 litres of red color.

Answer:
12.5 miles per hour
Step-by-step explanation:
Math
Answer:
12.5 MPH
Step-by-step explanation:
Miles per hour can also be written as miles/hour
therefore 3.75 miles in .3 hours can also be written as 3.75 miles/.3 hours
3.75 / .3 = 12.5
Therefore the cyclist was going 12.5 miles per hour
