Answer:

Angle ABC = 66 degrees

Step-by-step explanation:

Let's first focus on Triangle BHC

The formula to find the third angle of a triangle is that all 3 sides must add up to 180 degrees.

We can immediately see that Angle FAB and Angle BHG is equal since they are alternating interior angles.

We are then given that BCH is 18 degrees. Therefore the equation will be:

48 + 18 + ? = 180

The third side of Triangle BHC is 114 degrees.

Now, let's switch to what we actually need to find. (Angle ABC)

We can see that Angle HBC + Angle ABC = 180 degrees!

Substitute what we already know:

Angle HBC (114 degrees) + Angle ABC = 180 degrees.

Therefore, we end with:

Angle ABC = 66 degrees.

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:

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: 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.

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.

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:

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

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:

The door was opened by whom?

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.

< 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 ≤

Answer: 6hrs & 16mins

Step-by-step explanation:

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).
