Answer:
13.9
Step-by-step explanation:
Speed=distance/time
S=75,000/5,400
S=13.8 repeating OR (rounded) 13.9 m/s
Question 26 (1 point)
Find the distance between points P(7.1) and Q(5,7) to the nearest tenth.
PQ =
Answer:
The answer is 6.3 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
P(7,,1) and Q(5,7)
We have
[tex] |PQ| = \sqrt{ ({7 - 5})^{2} + ({1 - 7})^{2} } \\ = \sqrt{ {2}^{2} + ({ - 6})^{2} } \\ = \sqrt{4 + 36 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{40} \: \: \\ = 2 \sqrt{10} \\ = 6.32455532...[/tex]
We have the final answer as
6.3 units to the nearest tenthHope this helps you

Step-by-step explanation:
I believe the number of sides, and the number of lines of symmetry are the same.
Because, A "regular polygon" has all the same 5 sides all around, which would mean there's the same amount of lines of symmetry.
Given that m=r-s/2nr
Make r the subject .
PLEASE I NEED IT NOW.
THANK YOU . WHOEVER ANSWERS FIRST I WILL GIVE A FOLLOW AND BRAINLIEST
Step-by-step explanation:
[tex]m = \frac{r - s}{2nr} [/tex]
m(2nr) = r-s
2×n×r×m = r-s
move the r on the right side to the left side
2nrm - r = -s
r ( 2nm - 1 ) = -s
[tex]r \: = \frac{ - s}{(2nm - 1)} [/tex]

If the question is how many variable terms are in 3x^3y + 5x7 - 4y + x-z+9 the answer would be 7 because each of the variables are separated by the + and - signs and if you count them like that right now you would get 5 and if you add the 3 from the beginning you would get 7 saying that the variable terms are represented by the letters am I correct.
Given:
The expression is
[tex]3x^3y+5x^7-4y+x-z+9[/tex]
To find:
The number of variable terms.
Solution:
Constant values, variables, product of constants and variables are known as terms if they are separated by "+" sign.
The terms which contain atleast one variable is called variable terms.
We have,
[tex]3x^3y+5x^7-4y+x-z+9[/tex]
Here, the terms are [tex]3x^3y,5x^7,-4y,x,-z[/tex] and 9.
All terms contain variables except 9 which is a constant.
Therefore, the number of variable terms is 5.
Hence, your answer was not correct.

There are 1275 ants in 5 anthills how many are in 1 anthill?
Answer:
There are 255 ants in 1 anthill.
Step-by-step explanation:
Do the cross multiplication method. First set the equation as 1275/5 = x/1. Then cross multiply to get 5x = 1275. Divide both sides by 5 to get 255.

What is the slope of the line whose equation is y-4=(x-2)?
6
S
3 2
1
-5-5-32
+
23
5 x
2719 2
Answer:
1
Step-by-step explanation:
y-4=(x-2)
This equation is in point slope form
y-y1 = m(x-x1)
where m is the slope
The slope is 1
y - 4 = x - 2
y = x + 2
Slope-intercept form is y = mx + b, where m is the slope and b is a constant.
Here, m = 1 and b = 2. Therefore, the slope is 1.

ratio 4:12 simplified.
Answer:
1/3
Step-by-step explanation:
4/12
2 goes in to 4 and 12, so 4 divide by 2 is 2 and 12 divide by 2 is 6 then you have to simplify it again since 2 can still go into 2 and 6 so 2 divide by 2 is 1 and 6 divide by 2 is 3.

Which situation represents causation rather than correlation?
A. as the number of injured players on the sports team increases the number of fans attending the teams game increases
B. as more swimsuits are sold by department stores more sailboats are rented at the marina
C. as more people carry their umbrellas to work more people dress and heavier clothing
D. as a total number of family member increases the amount of money that the family spends on food increases
Answer: D. as a total number of family member increases the amount of money that the family spends on food increases
Step-by-step explanation:
Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'i.e. independent variable acts like a cause to effect the dependent variable.
This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.
Hence, there is direct effect of number of people on food's cost.
Rest of options represents correlation but not causation .
Hence, the correction option is D.
