What percent of the ninth graders scored above an 87?

Answer:

Question 5: The missing term her is r²

Question 6: The missing term here is 3.

Step-by-step explanation:

Question 5:

Let's write the equation and then solve it for the missing term. We will call this term x.

[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]

First, we simplify the letf term adding the similar terms.

[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]

Now, we substract 4r⁴ and 7r in both sides.

[tex]x=r^{2}[/tex]

Therefore, the missing term her is r²

Question 6:

Here, we will call the missing term y. Now, let's solve it for y.

[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]

Let's first distribute the minus sign into the parentehsis.

[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]

Now simplify the left side by adding similar terms.

[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]

Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.

[tex]y=10-7[/tex]

[tex]y=3[/tex]

Therefore, the missing term here is 3.

I hope it helps you!

There are 26 letters in the alphabet.

1st letter can be 1 of 26

2nd letter can be 1 of 25

3rd letter can be 1 of 24

4th letter can be 1 of 23

Total combinations = 26 x 25 x 24 x 23 = 358,800

Answer:

solution given:

total alphabet =26

The first letter can be any one of the 26 letters in the alphabet.

so

1st word =26letter

since no word is repeated

2nd word =25letter

3rd word=24letter

4th word=23letter

so

four-letter code =26×25×25×23=358800codes

so

358800codes of four-letter codes can be made if no letter can be used twice.

Answer: The answer is -22.

Answer:

-22

Step-by-step explanation:

PEMDAS

P - Parentheses/Brackets -> -6+[-2(6+2)] = -6+[-2(8)]

E - Exponents -> None

M - Multiplication left to right -> -6+[-2(8)] = -6+[-16]

D - Division left to right -> None

A - Addition left to right -> -6+[-16] = -6-16 = -22

S - Subtraction left to right -> See addition

Therefore, your answer is -22.

Answer:

WATER IS not wet

Step-by-step explanation:

Water is NOT wet by itself, however it makes other materials wet when it sticks to the surface of them.

Answer:

Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

Answer:

≈ 1468.59223 in squared

Step-by-step explanation:

1) A=2AB+(a+b+c)h

2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)

3) s=a+b+c / 2

4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4

5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223

≈ 1468.59223 in squared

Answer:

12,500 liters

Step-by-step explanation:

Given that

One cubic meter = 1000 liters

One cubic decimeter = 1 liter

We need to find out the number of liters fit in a 12.5 cubic meter

So

As it is mentioned that

One cubic meter = 1000 liters

So for 12.5 cubic meter

The number of liters would be

= 1000 × 12.5

= 12,500 liters

Answer:

3^3 - 4+6 = 17

Step-by-step explanation:

First you would do the exponents. 3 to the power of 3 (3^3) is 27.

Then you would add 4 and 6 (4+6) which will give you 10.

Finally, you would need to subract 10 from 27 (27-10) and you would get 17.

Hope this helps! :)

Answer:

29

Step-by-step explanation:

The expression is

a^3 - b + c

You just have to plug in the numbers, then evaluate,,

(3)³ - (4) + (6)

Let's start off with the exponent, so (3)³ = 3×3×3

3×3=9

9×3=27

Now, we have 27 - (4) + (6)

We have to get rid of the parenthesis so multiply the symbol next to it, - × 4 = -4, and + × 6 = +6. Now rewrite the equation.

27 - 4 + 6

27 - 4 = 23

23 + 6 = 29

Therefore, the answer its 29.

Answer:

2.5

Step-by-step explanation:

The radius is any line from the middle of the circle to the end of the circle. The diameter is a chord which is a line going from any end of the circle to the other end but the diameter crosses though the point which is in the middle.

So, you split the diameter in half. 5/2 = 2.5

Answer:

-5, +3.4, -3.35, and- 9 1 3

Step-by-step explanation:

To find the opposite of any number we multiply it with -1 or divide it with -1

The opposite of 5 is given by  5 (-1)= -5

The opposite of -3.4 is given by  -3.4 (-1)= 3.4

The opposite of 3.35 is given by  3.35 (-1)= -3.35

The opposite of 913 is given by  913 (-1)= -913

This property is called the additive inverse. The additive inverse is that property which on addition of the numbers gives the answer = zero.

5-5= 0

-3.4+3.4= 0

3.35-3.35=0

913-913=0

Answer:

68 games

Step-by-step explanation:

Given data

out of 100%

they lost 15%

Let the total game played be x

so

15/100*x= 12

0.15x= 12

x= 12/0.15

x= 80 games

the total games played is 80

Hence the games won

=total games-games lost

=80-12

=68 games

Answer:
