Answer 1

One is given the following information:

Triangle (ABC) is an isosceles triangle (meaning two of its sides are congruentSide (AB = AC)

One property of an isosceles triangle is the base angles theorem. This states that in an isosceles triangle, the two angles that are opposite the congruent sides are also congruent. Applying this theorem here, one can state the following:

[tex]AB = AC\\\\m<C = m<B[/tex]

The sum of angle measures in a triangle is (180) degrees. One can apply this here by stating the following:

[tex]m<A+m<B+m<C=180[/tex]

Substitute in the proved information: express angle (<C) in terms of angle (<B).

[tex]m<A+m<B+m<C=180[/tex]

[tex]m<A+m<B+m<B=180[/tex]

Simplify, combine like terms.

[tex]m<A+m<B+m<B=180[/tex]

[tex]m<A+2(m<B)=180[/tex]

Inverse operations: solve for angle (<B)

[tex]m<A+2(m<B)=180[/tex]

[tex]2(m<B)=180-(m<A)[/tex]

[tex]m<B=\frac{180-(m<A)}{2}[/tex]

Simplify,

[tex]m<B=\frac{180-(m<A)}{2}[/tex]

[tex]m<B=90-\frac{(m<A)}{2}[/tex]

Thus, one has proven that the statement ([tex]m<B=90-\frac{(m<A)}{2}[/tex]) is true.

Please note, this proof can be typed in a statement-reason format, where the bolded part of the written words above the statement is the reason.

Alexandra's family took a road trip to the Grand Canyon. Alexandra slept for the last 48 miles of the trip. If the total length of the trip was 800 miles, what percentage of the total trip had they travelled when Alexandra fell asleep

Answers

Answer:

She fell asleep for 6% of the trip.

Step-by-step explanation:

You take 48 and divide it by 800. That gives you 0.06.

0.06 equals 6%.

Answer:

6%

Step-by-step explanation:

Divide 48 and 800 together.

48/800 = 0.06

48 is the miles she's sleeping and 800 is the total miles.

So, she was asleep only 6% of the trip.

Find the value of x in the equation below.
48 = 6x

Answers

Answer:

x=8

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra, to find x you must isolate the variable. To do this, use the property of equality. This property states that an equation is still true if you do the same thing to both sides. For example, the equation would still be true if you added 1 to both sides.

To isolate x divide both sides by 6. This equals 48/6 = 6x/6. Which simplifies to 8=x.

rovers,United and City are football teams
rovers scored x goals
United scored 8 goals more than rovers
City scored 3 goals less than twice the number of goals scored by rovers
the three teams scored a total of 117 goals
solve to find the value of x​

Answers

Based on the information given, the value of x is 28 which means that Rovers scored 28 goals.

Number of goals scored by Rovers = x

United scored 8 goals more than rovers. This will be = x + 8

City scored 3 goals less than twice the number of goals scored by rovers. This will be: = 2[x} - 3 = 2x - 3

Since the three teams scored a total of 117 goals, this will be:

x + x + 8 + 2x - 3 = 117

Collect like terms

4x = 117 - 8 + 3

4x = 112

x = 112/4

x = 28

The value of x is 28

let S = (x, y) , then

[tex]\frac{x+0}{2}[/tex] = 1 ( multiply both sides by 2 )

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 5x + 3 = 23. To calculate the value of 12x -10 first calculate the value of x.

5x+3 = 23

5x = 23-3

x = 20/5

x = 4

Calculate the value of 12x - 10.

12x-10 = ?

12x-10 = 12 (4) -10

12x-10 = 48 -10

12x-10 = 38

Therefore, the value of the expression 12x - 10 will be 38.

Tom wins at chess 180 times in every 250.Daisy wins three quarters of the time.Jacob wins 328 times in every 400?Work out who has the best percentage score.

Answers

Daisy bc if you add up 250 plus three quarters is 325

Answer:

Jacob has the best percentage score of 82%

Step-by-step explanation:

Tom wins at chess 180 times in every 250

Daisy wins 3/4 of 180 times

Jacob wins 328 times in every 400

Tom's percentage score = [tex]\frac{180}{250} * 100[/tex] = 72%

Daisy wins [tex]\frac{3}{4} * 180 = 135[/tex] times

Daisy's percentage score = [tex]\frac{135}{250} * 100[/tex] = 54 %

Jacob's percentage score = [tex]\frac{328}{400} * 100[/tex] = 82%

Somebody help !!!!!!!!!!!!!!!!

Answers

Hey there! I'm happy to help!

The equation y=0.5x simply means that Joseph is hiking 0.5 miles every hour. This is because the x value is the independent variable or the thing you change, which in this case is the time you take hiking. The distance, the y-value, is dependent on that time.

Now, let's look at Kelly's graph. This graph isn't a grid, so we will have to eyeball some of the numbers on the graph. It appears that after 10 hours, Kelly has traveled eight miles. This is because if you go up from the 10 and meet the line and then go to the left. you will be about at the line right below the 10 on the y-axis, and if you count the lines, you will see that we are counting by 2, so it has to be eight.

So, we see that Kelly takes 10 hours to go eight miles. We know that Joseph's distance is half of his time (4 hours would be 2 miles, 6 hours would be 3 hours, etc.)

So, if we say that Joseph hikes for ten hours, he will have hiked five miles as that is half of ten. We see, though, that Kelly made it eight hours in that time, so Kelly is going faster here.

Have a wonderful day and keep on learning! :D

Kelly hikes at the rate of 1mile per hour.

Or, y = x.

If Joseph hikes at the rate of y = 1/2x, and kelly hikes at the rate of y = x,

Kelly hikes faster than Joseph

Answers

Answer: D

Step-by-step explanation:

100!=2*3*4*...*100

Counting which numbers are divisible by 2:

2,4,6,8,10,12,14,...,96,98,100 : 50 numbers (100/2=50)

Counting which numbers are divisible by 4=2²:

4,8,12,16,20,...96,100: 25 numbers (100/4=25)

Counting which numbers are divisible by 8=2³:

8,16,24,32,40,...,96: 12 numbers (100/8=12.5 ==> 12)

Counting which numbers are divisible by 16=2⁴:

16,32,48,...,96: 6 numbers (100/16=6.25 ==> 6)

Counting which numbers are divisible by 32=2⁵:

32,64,96 : 3 numbers(100/32=3.125 ==>3)

Counting which numbers are divisible by 64=2⁶:

64 : 1 number (100/64=1.5625 ==>1)

Sum of those numbers= 50+25+12+6+3+1=97

100! is divisible by 2⁹⁷.

Answer D

There are 50 even numbers - divisible by 2
There are 25 multiples of 4
There are 12 multiples of 8
There are 6 multiples of 16
There are 3 multiples of 32
There is one multiple of 64
Each of these is also counted in the line above

So the unique multiples are (1 x 64) x (2 x 32) x (3 x 16) x (6 x 8) x (13 x 4) x (25 x 2)
= (1 x 2^6) x (2 x 2^5) x (3 x 2^4) x (6 x 2^3) x (13 x 2^2) x (25 x 2^1)
So n = 6 + 10 + 12 + 18 + 26 + 25 = 97

The slow (but easier way) to see this is to write down all the even numbers in factors of 2 and count the number of 2S
Eg 2, 2x2, 2x3, 2x2x2, 2x5, 2x2x3, 2x7, 2x2x2x2, 2x9, 2x2x5, 2x11, 2x2x2x3, 2x13, 2x2x7, 2x15 etc
(This only got to 30 but you should get the idea - there are 26 twos up to there)
