Niall poured 2.5 liters of sports drink on
each of his two bandmates' heads after a
concert. How many centiliters did he
dump all together?

Answer:

48

Step-by-step explanation:

50 + 88= 132

in triangle abc,

132+L=180

L=48

Answer:

Step-by-step explanation:

The first step will always be to break it down into steps.

Nathan lifted 13 boxes, each weighing 12 lb more than Steven's boxes. Steven lifted 15.

The total weight of Nathan's boxes would be the weight of 1 box times 13, because he lifts a total of 13 boxes.

S is the weight of Steven's boxes.

Steven's box + 12 lb = the weight of one of Nathan's boxes.

Then, you would multiply that number by 13 to get your answer.

Therefore, the first option is correct.

13(s + 12)

number of boxes Nathan lifted(Steven's weight + the extra pounds)

Hope this helped!

Answer:

13(s + 12)

Answer:

X equals negative 11

Step-by-step explanation:

The angles in a triangle add up to be 180 degrees, and we already have 80 as one angle and 60 as the other. That equals 140 degrees. But now we have x+51. That would equal 191 degrees, so 191-180=11, so x= -11

Answer:

x=-11

What we know=

Angles A'=x+51

Angle B=60

Angle C=80

Angle B' and C'=?

Due to the vertically opposite angle rule, we know angle B' and C' are the same as angle B and C.

So, angle B' is 60 degrees. Angle C' is 80 degrees.

We can add them together to get 140 degrees.

So we have 140, x+51. We can make an equation.

[tex]180=140+51+x[/tex] We can combine like terms (140 and 51) to get 191

A triangle only adds up to 180 degrees. So now you can subtract 180-191=to get x.

Answer:

22.5 (B)

Step-by-step explanation:

Step-by-step explanation:

the sum of all angles in a triangle is always 180 degrees.

so,

x + 12 + 2x - 29 + x + 5 = 180

4x - 12 = 180

4x = 192

x = 48

Answer:

130 and 211

Step-by-step explanation:

15+17= 32

17+32=49

32+49=81

49+81=130

81+130=211

Answer:

130 and 211

Step-by-step explanation:

15,17,32,49,81 _ _

15+2=17+15=32+17=49+32=81

that mean 81+ 49=130

and 81+130= 211

Hence, the answer is 130 and 211.

Answer:

the desired element lies in the 3rd row and 1st column, and is 25.

Step-by-step explanation:

We are given a 3 by 3 matrix:  There are 3 rows and 3 columns.

The symbol a       represents the element of this matrix that lines in row m and column 1.  Thus, the desired element lies in the 3rd row and 1st column, and is 25.

Answer:

Step-by-step explanation:

Sum: 6 * 10^-4 + 1.5*10^-4 = 7.5 * 10^-4

Difference: 6 * 10^-4 - 1.5 * 10^-4 = 4.5 * 10^-4

Product: 6*10^-4 * 1.5 * 10^-4 = 9 * 10^-8

Quotient: 6*10^-4/1.5 * 10^-4 = 4

Notice the answers, because they give you the rules.

When adding exponents and rationales, if the powers are the same then the rationales merely add.

Same rule applies to subtraction. Retain the powers and subtract the rationales.

When multiplying the rationales multiply, but the rationales add. they don't stay the same.

When dividing, the rationales divide and the powers subtract -- numerator minus denominator

Answer:

Step-by-step explanation:

there are several ways. if u have angels use cos or sin therom. if u have a 90 degree angle use The Pythagorean Theorem. send it completely

Answer:

Before one can solve for the width of a rectangle(the value of the area or perimeter must be given and the length)

Using the area

Length = l

Width =w

Area = a

a = l × w ; a = lw

w = a/l

using perimeter(p)

p = 2(l+w)

p/2 = l+w

p/2 - l = w

w = p/2 -l

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

Mode is that number that appears most frequently in the given set of data.

We are given that  the ages in years of members of group 8, 11, 8,10 ,6, 7, 3x ,11, 11 if the mean age is 9 years

3x = 3(2 )= 6

Mean = (6,7,8,8,9,10,11,11,11)/9

= 81/9

= 9
