Answer:

180 inches

Step-by-step explanation:

36x5= 180

Answer:

if she already has 36 inches and we are tying to find how much she need we need to take that 5 and multiple it to the 36 because the word TIMES means to multiple so 36x5= 180. so your answer will be she will need 180 in (since that is the measurement we are using)

-3(-3) = 9

Product of two negatives is positive

Answer:

yes, -3 is a solution of -3x = 9

Step-by-step explanation:

substitute -3 for x in the equation

-3x = 9

-3*-3 = 9

9 = 9

since 9 does in fact equal 9, the answer is yes!

C. tan(30°)

Step-by-step explanation:

edge yuh yuhhhhh

The equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].

The given expression is tan 40°-tan 10°/1+tan 40°.tan 10°.

When simplifying trigonometric expressions, one approach is to change everything into sine or cosine.

Now, [tex]\frac{\frac{sin40\textdegree}{cos40\textdegree} -\frac{sin10\textdegree}{cos10\textdegree}}{1+\frac{sin40\textdegree}{cos40\textdegree} .\frac{sin10\textdegree}{cos10\textdegree} }[/tex]

=[tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex]

Therefore, the equivalent fraction is [tex]\frac{sin 40\textdegree. {cos10\textdegree} - {sin 10\textdegree}{cos40\textdegree}}{{cos 40\textdegree. {cos10\textdegree} + {sin 10\textdegree}{sin40\textdegree}}}[/tex].

Answer:

17 miles

Step-by-step explanation:

Answer: 63 children and 88 adults swam at the public pool that​ day.

Step-by-step explanation:

Let x = Number of children

y= Number of adults

As per given , we have

x+y=151            (i)

1.50x+2y=270.50          (ii)

Multiply 2 on both sides of (i)

2x+2y = 302          (iii)

Eliminate (ii) from (iii)

0.5x=31.5

⇒ x = 63   [Divide both sides by 0.5]

Put value of x in (i) , we get

63+y= 151

⇒ y= 151-63 =88

Hence, 63 children and 88 adults swam at the public pool that​ day.

Answer:

11n

Step-by-step explanation:

We don't know the value of N, so we leave that the same.

3 to the second power, (3x3)= 9.

We have to add 2 to 9, so 9+2=11

Add your n to the end, and your answer is 11n.

Complete Question

The area A (in square feet) of the rectangular shed is given by 6x³+7x²+11x+21.And one side of the rectangular is 2x+3. Use polynomial long division to find an expression for the length (in feet) of the shed.

Answer:

3x² - x +7

Step-by-step explanation:

Using the long division method:

We have :

Divisor : 6x³+7x²+11x+21

Dividend : 2x+3

Quotient : the length (in feet) of the shed = ???

Hence, we solve below

6x³+7x²+11x+21 ÷ 2x + 3

3x² -x + 7

______________________

2x+3 l 6x³+7x²+11x+21

Answer:

The constant of proportionality is 490

The jet will take 12 hours to travel 5,880 miles

Step-by-step explanation: The miles multiply by 490 each time.

490 x 12 is 5,880

The constant of proportionality is k = 490 and the equation is y = 490x where x is the number of hours and y is the total number of miles

The time required is 12 hours

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the distance of the aircraft be = x

Let the total time taken by the aircraft be = y

Let the constant of proportionality be k

when x = 1 ,

y = 490

So , the equation will be y = kx

Substituting the values in the equation , we get

y = 490x

when x = 2

y = 490 ( 2 )

y = 980

Now , the time taken by aircraft to travel 5,880 miles is

Substitute the value of y as 5880 in the equation , we get

5880 = 490x

Divide by 490 on both sides of the equation , we get

x = 5880 / 490

x = 12

Therefore , the time taken is 12 hours

Hence , the constant of proportionality is 490
