Answer:

46.07

Step-by-step explanation:

CAH (cosine=adjacent/hypotenuse)

cos (71)=15 (adjacent)/x (hypotenuse)

x=15/cos(71)

x=46.07

Answer

so what you do is

Step-by-step explanation:

do Cos71= 15/x

becomes x times cos71 = 15

becomes x =  15/cos71

then if u put in calculater and type 15 divided by the cos of 71 and make sure oyur calculater is on degrees an you will get answer

Answer:

His percentage profit is 12%

Step-by-step explanation:

Here, we want to calculate the percentage profit made by the business man.

Per kg of what he is selling, he has 3 parts high quality sugar and 5 parts low quality sugar.

Now let’s see how much these costs

For the high quality sugar, it’s total kg mixed per kg will be 3/(3+5) = 3/8

Since high quality sugar costs 10 shillings per kg, 3/8 of a kg will cost 3/8 * 10 = 30/8 = 3.75 shillings

For the low quality, its part will be 5/(3 + 5) = 5/8

since low quality costs 8 shillings per kg, 5/8 of a kg will cost 5/8 * 8 = 5 shillings

Total cost price = 3.75 + 5 = 8.75 shillings

% profit = (selling price - cost price)/cost price * 100%

selling price here is 9.8 shillings per kg

while cost price is 8.75 shillings per kg

% profit = (9.8-8.75)/8.75 * 100%

= 1.05/8.75 * 100% = 0.12 * 100% = 12%

Answer:

119 g.

Step-by-step explanation:

11 cm has a mass of 187 g

So 1 cm has a mass of 187/11 g

7 cm ...............................  (187/11) * 7

= 17 * 7

=  119 g.

Answer: 2.4%

Step-by-step explanation:

SI = prt / 100

96 = ( 800 x r x 5) / 100

96 = 40r

r = 96 / 40 = 2.4%

Answer:

p=10 when q=15

Step-by-step explanation:

p and q are inversely proportional

It means

p=k/q

p=25 when q=6

p=k/q

25=k/6

k=25÷1/6

k=25×6/1

=150

k=150

Find p when q=15

p=k/q

p=150/15

=10

p=10

[tex]\fbox{\begin{minipage}{3em}x = 6\end{minipage}}[/tex]

Step-by-step explanation:

Given:

Equation: [tex]3x - 3 = 27 - 2x[/tex]

Solve for:

[tex]x[/tex]

Solution:

Step 1: Select relevant approach:

Let's move all the components containing x to the left side and other components to the right side (notice the change of sign of each one from + to - or - to +), then calculate [tex]x[/tex]

Step 2: Perform the calculation:

      [tex]3x -3 = 27 - 2x[/tex]

Moving components:

<=> [tex]3x + 2x = 27 + 3[/tex]

Adding up components:

<=> [tex]5x = 30[/tex]

Dividing both sides by 5 (coefficient of component containing [tex]x[/tex]:

<=> [tex]\frac{5}{5} x = \frac{30}{5}[/tex]

Simplifying to work out [tex]x[/tex]:

<=>[tex]x = 6[/tex]

Hope this helps!

:)

Answer:

x = 6

Step-by-step explanation:

3x - 3= 27 - 2x

First we put all the x terms to on side, making it 3x + 2x - 3= 27.

Remeber that when we move a term to the other side of the equals sign (=), we change its sign to be the opposite of what it currently is.

Then, we move all the numberics to the other side, so we derieve 3x + 2x = 27 +3. Again, the sign changes when we move it across.

What is left to do is add up the quantities. So 3x + 2x = 5x and 27 +3 = 30.

We are left with 5x = 30. If 5 x's is 30, how much is one? Sinply divide it to get the answer of 30 / 5 which is six!

To make sure the answer is correct substituite 6 in the equation as x and see if its accurate: 3(6) -3 = 7 - 2 (6). And it is!

So x is equal to six.

Answer:

I don't understand the question

Answer & Step-by-step explanation:

The figure shown in the diagram is a square. Squares have equal lengths on all sides. So, in order to find out the side length, we will have to factor the area.

x² - 12x + 36

First, you will break down x² which will just be x and x. Since 12x is negative and 36 is positive, then we will use a minus sign.

(x - )(x - )

Now, we break down 36 which will be 6 and 6. After we do that, we will have our answer.

(x - 6)(x - 6)

So, the side length of the square is (x - 6) meters.

how to find the correct one?

just see on the x² constant number. it's -5 so

from ABCD the only option give -5 is C

Answer:

12

Step-by-step explanation:

Took the test on edg I got 100%.

Answer:

12

Step-by-step explanation:

Adding a to both sides of the second equation we get b = a+1

Substituting this in we get

10a + 10 - 9a=6

a +10 =6

a=-4

Putting this back in to the second one we get b+4=1

B=-3

-4*-3=12

The value of ab = 36.

We have the following equations -

10b - 9a = 6

b - a = 1

We have to determine the value of ab.

We have -  [tex]a^{2} -b^{2} = \pi[/tex]

(a + b) (a - b) = [tex]\pi[/tex]

a - b =  [tex]$\frac{\pi }{4\pi }[/tex]  = 1/4

According to question, we have -

10b - 9a = 6

b - a = 1

Now -

b - a = 1

a = b

Therefore -

10b - 9a = 6

10b - 9b = 6

b = 6 = a

ab = 6 x 6 = 36

Hence, the value of ab = 36.
