Answer:

l =10 units, 9.7 units, 5.5 units

Step-by-step explanation:

Area = length x breadth

Area of a square = l^2

100= l^2

√100 =√l^2

l=10 units

95=l^2

√95 = √l^2

l= 9.7 units

30=l^2

√30=√l^2

l= 5.5 units

Answer:

The answer would be B.

Step-by-step explanation:

It couldn't be A because it  just doesn't make sense because if the dot means a student then what are the numbers on the bottom mean.

It also couldn't be D because nowhere does it say anything about teachers.

Hope this Helps! :)

Answer:

(n +54)/9 = 21; 135= n

Step-by-step explanation:

(n+54)/9 = 21

n+54/9 *9= 21*9

n+54-54 = 189-54

n= 135

the first part is simply recognizing the order its written and the words used.

So to start off with, they use the turn "a number" so we know there's going to be some form of a variable. From there it says "increased by" rather than "multiplied" or "doubled" or something of that nature, so we know its adding 54 rather than multiplying. Then, the next part says that "the sum" which is another key term for addition, "is then divided by 9". So we can assume so far that a variable plus 54 is added together to get a number, which is then going to be taken and divided by 9. The last part says "the result is 21", which simply means that we need to end up with 21.

So once we gather all this information, we can put it together as so: (n +54)/ 9 = 21.

I put parentheses around the n + 54 to make sure that the equation is following the system of equations (PEMDAS).

Answer:

46.6028 Miles

Step-by-step explanation:

If you're looking for the amount of miles they'd traveled, this is the exact amount. If you're looking for your answer in Kilometers, they'd travel 70 km total.

35 km/hr x 2 = 75 km total

Hope this helped! If it didn't let me know what you need help solving.

Answer: 88 degrees; acute triangle

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).

Answer:

Noah did not make any errors

Step-by-step explanation:

The median is a list of strictly increasing numbers is simply the middle number. if there's an even number of numbers in the list,  then the median is the average of the middle terms.

here, the numbers are 115, 109, 117, 136, 127, 131. when ordered from least to greatest we get 109, 115, 117, 127, 131, 136 which is what Noah got.

since there are 6 numbers (6 is even), the median will be the average of the middle two numbers which are 117 and 127: (117+127)/2=244/2=122

so Noah is was correct.

Hey there!

2/3 = a/30

First: you have to CROSS MULTIPLY the given numbers

2(30) = 3(a)

2(30) = 60

3(a) = 3a

New EQUATION: 3a = 60

Second: DIVIDE 3 to BOTH SIDES

3a/3 = 60/3

CANCEL out: 3/3 because that gives you 1

KEEP: 60/3 because that helps you solve for your a-value

60/3 = a

60/3 = 20

Therefore, your answer is: a = 20

Good luck on your assignment and enjoy your day!

Answer:

d = t(.7)

Step-by-step explanation:

We can start by dividing the values on the right by the values on the left.

Starting with the first one, 7/10=.7

It gives us .7

To double check this we can use the second values, 10.5/15=.7

It gives us .7

and even if we still aren't sure we see the last value also gives us the same answer, 14/20=.7

This means that if we multiplied the time by .7 for any of the time values, we would get our distance values.

Answer:

No, it is a quadratic function.

Step-by-step explanation:

An exponential function has the variable as the exponent. 3^x would have been an example of an exponential function. In this function, the exponent is not variable, it is 2. Therefore this is a quadratic function, not an exponential one.

Answer:

Step-by-step explanation:

1). By applying Pythagoras theorem in the triangle formed by two sides and the diagonal,

Length of the diagonal = [tex]\sqrt{(\text{side})^2+(\text{side})^2}[/tex]

                                      = [tex](\text{side})\sqrt{2}[/tex]

                                      = 25√2

                                AC ≈ 35.56 units

2). Since, diagonal of a square is the angle bisector of interior angles of the square,

m∠CAB = 45°

By applying sine rule in ΔABC,

sin(45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{AB}{AC}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{25}{AC}[/tex]

AC = 25√2

AC ≈ 35.56 units

Answer:

P(pink or even) is [tex]\frac{9}{10}[/tex].

Step-by-step explanation:

Since the cards that meet the requirement can be pink or even, that means there are 9 cards that meet the requirement. Since there are a total of 10 cards, that means P(pink or even) is [tex]\frac{9}{10}[/tex].

Based on the cards shown, P(pink or even) is equal to 9/ 10.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The cards that meet the requirement can be pink or even, which means there are 9 cards that meet the requirement.

Since there are a total of 10 cards, that means P(pink or even) is 9/ 10.

-4÷2 = -2

8÷(-4) = -2

-16÷8 = -2

So this is a geometric sequence with the first term of 2 and a common ratio of -2

Answer:

1,900 votes were in favor.

Step-by-step explanation:

Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:

2000*95%=1900

According to this, the answer is that 1,900 votes were in favor.

Answer:

$5x + $4y ≤ $120

let x = 10

y = 5

$70  ≤ 120

Step-by-step explanation:

Note that

> means greater than

< means less than

≥  means greater or equal to

≤ means less than or equal to

the total amount Shanley has is $120. She can spend less than this amount or the amount exactly. So, the inequality sign to be used is ≤

$5x + $4y ≤ $120

let x = 10

y = 5

(50) + 20  ≤ 120

$70 ≤  120
