Find the distance between (-1,2) and (4,0)
Answer: The distance between (-1,2) and (4,0) is about 5.4 units
Step-by-step explanation: You can use the Pythagorean Theorem to calculate the distance.
The difference in x-values is one side of the triangle 4- (-1) = 5 Side a
The difference in y-values is the other side 0- 2 = -2 Side b
The distance you are looking for is the hypotenuse, side c
Pythagorean Theorem : substitute the numbers we found for a and b
c² = a² + b²
c² = 5² + -2²
c² = 25 + 4
c² = 29
29 is the "square on the hypotenuse." So take the square root (use a calculator)
√29 = 5.385
You can round that to 5.4 units

Solve the following for x
(5x+6)/(8x+5)
X=
Answer:
x = 13
Step-by-step explanation:
The sum of these two equations has to equal 180 since they are adjacent to each other. Combine the two equations with an addition sign inbetween and set it equal to 180.
5x+6+8x+5 = 180
13x+11 = 180
13x = 169
x = 169 / 13
x = 13
To check your answer plug in 13 for x in each equation, you should get 71 degrees for 5x+6 and 109 degrees for 8x+5. Adding 71 and 109 gives you 180, so the answer is correct.
∠(5x + 6)° and ∠(8x + 5)° are a linear pair, which means their sum will add upto 180° .
Which means :-[tex] = 5x + 6 + 8x + 5 = 180[/tex]
[tex] = 13x + 6 + 5 = 180[/tex]
[tex] = 13x + 11 = 180[/tex]
[tex] = 13x = 180 - 11[/tex]
[tex] = 13x = 169[/tex]
[tex] = x = \frac{169}{13} [/tex]
[tex]\implies\color{olive} {\: x =\color{hotpink} 13}[/tex]
Then :-∠(5x + 6)° :-
[tex] = 5 \times 13 + 6[/tex]
[tex] = 65 + 6[/tex]
[tex]\color{olive}∠(5x + 6)°\color{hotpink} = 71° [/tex]
∠(8x + 5)° :-
[tex] = 8 \times 13 + 5[/tex]
[tex] = 104 + 5[/tex]
[tex]\color{olive}∠(8x + 5)°\color{hotpink} = 109° [/tex]
As the measure of both angles are adding up to form 180° (71+109=180), we can conclude that we have found out the correct value of x .
Therefore , the value of :-
[tex]\boxed{\color{hotpink}x = \bold13}[/tex]

Answer:
BC=9
Step-by-step explanation:
AC=AB+BC
26=9x+8+7x+2
16x+10=26
16x=16
x=1
BC = 7*1+2=7+2=9
Answer:
BC = 9
Step-by-step explanation:
First, you need to find what x is and then plug it into the equation for BC.
You can do this by setting both equations equal to 26, which is the total length.
9x+8+7x+2=26
16x=16
x=1
Now that we know x is 1, plug it into BC:
BC = 7(1)+2
BC = 7+2
BC = 9
Ashley has 5 bags of flour. She has two smaller bags with .75 ounces in each and 3 bigger bags which has 1.14 ounces in each. How much flour does she have in total?
Answer:
4.92 ounces
Step-by-step explanation:
Ashley has 5 bags of flour
She has two smaller bags with .75 ounces in each
= 2 × 0.75 ounces
= 1.5 ounces
3 bigger bags which has 1.14 ounces in each.
= 3 × 1.14 ounces
= 3.42 ounces
How much flour does she have in total?
This is calculated as
1.5 ounces + 3.42 ounces
= 4.92 ounces
Therefore she has 4.92 ounces of flour in total.

Mr. Thompson rents the kayak for 2 hours
and he rents the paddleboard for 3 hours.
What is the total cost of the rental?
Answer: 92
Step-by-step explanation: 18k + 22p - 10 = 18(2) + 22(3) - 10 = 36 + 66 - 10 = 92
The expression for the total cost is 18k + 22p - 10. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given:
Paddle board= $22/h
Kayak = $18 / h
and coupon of $10
Thompson travel for 'k' hours in the kayak and 'p' hours on the paddleboard then the expression will be formed as:-
18k + 22p - 10
Here (-10) represents a discount from the coupon of $10.
Therefore, the expression for the total cost is 18k + 22p - 10. The correct option is C.

The first term of a certain sequence is 6 and the
second term is 12. The third term and each
term thereafter is found by taking the average
of the two terms preceding it. What is the value
of the first term in the sequence that is not an
integer?
Answer:
[tex]\frac{21}{2}[/tex]
Step-by-step explanation:
Given
a₁ = 6
a₂ = 12 , then
a₃ = [tex]\frac{6+12}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 ← an integer
a₄ = [tex]\frac{12+9}{2}[/tex] = [tex]\frac{21}{2}[/tex] ← not an integer
Thus the fourth term is not an integer

Kevin moved from a city to a small town. The population of the city is 8*10^4 is about 20 times as great as the small town. What is the approximate population of the small town?
Given:
Population of city = [tex]8\times 10^4[/tex]
It is about 20 times as great as the small town.
To find:
The approximate population of the small town.
Solution:
Population of city is about 20 times as great as the small town. It means,
[tex]\text{Population of city}=20\times \text{Population of small town}[/tex]
[tex]\dfrac{\text{Population of city}}{20}=\text{Population of small town}[/tex]
On substituting Population of city = [tex]8\times 10^4[/tex], we get
[tex]\text{Population of small town}=\dfrac{8\times 10^4}{20}[/tex]
[tex]\text{Population of small town}=\dfrac{8\times 10\times 10^3}{20}[/tex]
[tex]\text{Population of small town}=4\times 10^3[/tex]
Therefore, the population of the small town is [tex]4\times 10^3[/tex].
A survey of 136 American adults measured each participants weight in pounds. If their individual weights were placed in order from smallest to largest give the position (location) of the median. If the median is located between two values give the location of the two middle values
Answer:
the location of the two middle values are ; (68th and 69th) terms
Median = (68th + 69th) / 2
Step-by-step explanation:
Median can be simply referred to as the middle value if the sample number size (n) is an odd number or average of the two middle values in a given data set if the sample number size (n) is an even number
the given data set has to be arranged from the smallest number to the biggest number before taking the middle number as median or taking the average of the two middle number as median if the sample number size (n) is an even number.
Here our n = 136 which is an even number
So,
Median = Average of the two middle numbers
= [ (n / 2)th term + ((n/2) + 1)th term ] /2
= [ (136/2)th term + ((136/2) + 1 )th term ] /2
Median = (68th + 69th) / 2
therefore the location of the two middle values are ; (68th and 69th) terms

A rocket's path is modeled by y=-16t2 + 80t.
When will the rocket hit the ground?
Answer:
t=5
Step-by-step explanation:
y represents height above the ground.
so when it touches the ground height above the ground =0
y=-16t²+80 t
it will hit the ground when y=0
-16t²+80t=0
-16t(t-5)=0
either t=0 or t-5=0
or t=5
t=0 gives initial value.(rejected)
t=5

Instructions: Write an expression to represent the given scenario.
Nick wants to save up enough money to go to Carowinds for the day with a group of his friends. He already has $50 saved up and plans to save $10 each week. Write an expression that represents the total amount Nick will have depending on the number of weeks (w) he saves for.
Answer:
y = 50 + 10w
Step-by-step explanation:
Since he already has 50 dollars you can add that to the amount PER week. Which is 10w
So that means 50 + 10w would be part of the equation and you can place y to represent the total amount.
y = 50 + 10w
