Answer:

Mode...

7

Step-by-step explanation:

To find the mode, order the numbers lowest to highest and see which number appears the most often.

and in the list...

8,6,7,9,7,0,2,3,5,7,8,9,69

7 is being repeated.

so mode is 7

Step-by-step explanation:

Pythagoras (for right-angled triangles) :

c² = a² + b²

c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.

c = diagonal = 10 ft

therefore, the width of the rectangle is 10/2 = 5 ft

10² = 5² + b²

100 = 25 + b²

b² = 75

b = length = sqrt(75) = 8.660254038... ft

Let's factorise it :

[tex]\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) }[/tex]

[tex]\: {\qquad \dashrightarrow \sf {x}^{3} (x + 3) + [-5(x + 3)] }[/tex]

Using Distributive property we get :

[tex]\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} + ( - 5x - 15) }[/tex]

[tex]\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} - 5x - 15 }[/tex]

[tex]\: {\qquad \dashrightarrow \sf 4{x}^{3} - 5x - 15 }[/tex]

⠀

Therefore,

14/29

Step-by-step explanation:

Answer:

total numbers of class = 15+14 =29

and number of girls in the class is 14girls

while probability = number of possible outcome

number of required outcome

therefore 14/29 is the probability of selecting

14x98 divide that by 2 and multiply ur chairs and width of the desk

Answer:

B

Step-by-step explanation:

One table = 8 chairs = 2 on each side

2 tables = 12 chairs = 4 on 2 of 4 sides and 2 on the other 2 sides

3 tables = 16 chairs = 6 on 2 of 4 sides and 2 on the other 2 sides

Step-by-step explanation:

Let b be base and h be height

b = 11+h

Then the area would be hx b = h(11+h) = 11h + h^2

Perimeter = 2h + 2b

= 2h + 2(11+h)

= 2h + 22 + 2h

In order to multiply radicals, the following are needed:

It should be noted that the radical symbol represents the square root of a number and this can be found in algebra.

To multiply radicals, they have to have the same index. In this case, the index is the small number written on the uppermost line in the radical symbol.

Next, simply multiply the numbers under the radical signs and keep them there.

Lastly, if you've multiplied the radicals, they can be simplified to perfect squares.

71 adult tickets, 135 child tickets

Step-by-step explanation:

[tex]\textcolor{steelblue}{\text{\textcircled{1} Define the variables}}[/tex]

Let the number of adult and child tickets sold be a and c respectively.

[tex]\textcolor{steelblue}{\text{\textcircled{2} Form and label 2 equations}}[/tex]

Adult tickets +child tickets= total number of tickets sold

a +c= 206 -----(1)

Revenue from child tickets +revenue from adult tickets= total revenue

Revenue from child tickets

= number of child tickets sold ×cost of each ticket

= 2.65c

Revenue from adult tickets

= number of adult tickets sold ×cost of each adult ticket

= 5.70a

2.65c +5.70a= 762.45 -----(2)

[tex]\textcolor{steelblue}{\text{\textcircled{3} Solve by substitution}}[/tex]

From (1):

a= 206 -c -----(3)

Substitute (3) into (2):

2.65c +5.70(206 -c)= 762.45

Expand:

2.65c +1174.2 -5.70c= 762.45

Simplify:

-3.05c +1174.2= 762.45

-3.05c= 762.45 -1174.2

-3.05c= -411.75

c= -411.74 ÷(-3.05)

c= 135

Substitute c= 135 into (3):

a= 206 -135

a= 71

[tex]\textcolor{steelblue}{\text{\textcircled{4} Concluding statement}}[/tex]

Thus, 71 adult tickets and 135 child tickets were sold.

Answer:

Step-by-step explanation:

1)  the equation would be:

(2x+4)x(5x+1) because if the amount of ballpens are (2x+4) and the ballpens are $(5x+1) each, you would multiply them.

this is the expanded version of (2x+4)(5x+1)
{10x^2 + 2x + 20x + 4

10x^2 + 22x + 4}

2) (x^2 +1)(x+2) are multiplied to find the volume of the box

So when expanded it looks like this:

{x^3 + 2x^2 + x + 2}

3) (15a^2b^3) would be multiplied with (2a). This is because to find the total you would times the numbers.
so when expanded:

(15a^2b^3)(2a)

{(15a^3)(2ab^3)}

4) 5X(x+8)=33

5x+40=33

5x=33-40

5x=-7

X= -7/5

5) x-8=8x

8x-x = -8

7x=-8

X=-8/7

Hope this helps :)

Step-by-step explanation:

We can represent the time it took him to do the first assignment by X.

The second assignment took twice as long and can be written as 2x.

The third took him 8 more minutes than the second. This can be written as 2x + 8.

It took him 58 minutes in total.

So, we can write the following equation.

Step-by-step explanation:

The fractions are added in the usual way, and the result simplified. That involves finding a common denominator, and expressing each fraction in terms of it.

Here the denominators have no factors in common, so the common denominator is their product. That common denominator is the difference of squares, a "special product."
