Answer:
1.085 metres
Step-by-step explanation:
1 cm = 0.01 m
8.5 cm = 0.085 m
1m+0.085m=1.085 metres
Answer:
1.085 metres
Step-by-step explanation:
100 centimetres = 1m
what about 8.5 cm?
Divide the centimetres by 100
8.5/100 = 0.085m
Then add the metre(s) you already have which is 1
thus 0.085 + 1
1.085m

In a class of 60 children 3/10 we're absent. The rest were present. How many pupils are present.
Answer: 42
Step-by-step explanation:
Answer:
A class of 60 children
3/10 were absent
So we’re trying to find how many pupils are here (kids).
So lets use percentage.
Percentage means out of a hundred so 3/10 is 30/100.
Multiply 10 on each numerator/denominator and you’ll get 30/100.
Now 30/100 is 30 percent.
We are to find 30 percent of 60.
18 pupils are absent.
We’re trying to find who’s here so
60 - 18 = 42
42 pupils are present

In a group of 25 students at lunch, 10 prefer ketchup on their hamburger, 10 prefer mustard on
their hamburger, and 5 like both ketchup and mustard on their hamburger. The rest of the
students in the group prefer neither. What is the probability that a student selected from this
group will prefer ketchup or mustard on their hamburger?
Answer:
15/25 or 3/5 or 60%
Step-by-step explanation:
P(K or M) = P(K) + P(M) - P(K and M)
= [tex]\frac{10}{25}[/tex] + [tex]\frac{10}{25}[/tex] - [tex]\frac{5}{25}[/tex]

12. P (7,r) = 5040. Find r
A. 5
B. 6
C. 7
D. 8
Answer:
B
Step-by-step explanation:
P(7,r) = 5040
[tex]P(n,r)=\dfrac{n!}{(n - r)!}\\\\\\n = 7 \\\\\dfrac{7!}{(7 - r)!}=5040\\\\\\7! = (7-r)!*5040\\\\(7-r)!=\dfrac{5040}{7*6*5*4*3*2*1}\\\\\\(7-r)!=\dfrac{5040}{5040}\\\\\\(7-r)!=1\\\\[/tex]
(7 - r)! = 1!
7 -r = 1
7 = 1 + r
7 - 1 = r
r = 6
Answer:
12. B or C
13. C
14. A
15. A
Step-by-step explanation:
These problems involve various counting techniques. For combinations and permutations, there are formulas to aid in the counting. For other situations, you may need to list possibilities.
__
12.P(7, r) = 5040 . . . . . given
P(7, r) = 7!/(7 -r)! = 5040
5040/(7 -r)! = 5040 . . . . . evaluate 7!
(7 -r)! = 1 . . . . . . . . . . . multiply by (7-r)!/5040
We know that both 0! and 1! = 1, so this has two solutions:
7 -r = 0 ⇒ r = 7
7 -r = 1 ⇒ r = 6
Both choices B and C are correct.
The attached calculator output confirms this result.
__
13.The formula of choice C is correct:
C(n, r) = n!/((n-r)!r!)
__
14.The number of permutations of the 9 letters is reduced by the numbers of permutations of letters that are indistinguishable. That is, the 9 letters can be rearranged 9! ways, but the 4 Es are indistinguishable, so a factor of 4! must be removed from that result. Similarly, the two Ns and two Ss are indistinguishable, so additional factors of 2! must be removed. The number of arrangements is ...
9!/(4!2!2!) . . . . matches choice A
__
15.The 5 students can be arranged in 5 consecutive chairs in P(5, 5) = 5! = 120 ways. Those 5 consecutive chairs can start in chairs 1 through 6, so there are 6×120 = 720 ways the 5 students can sit together in 10 chairs.

do the lengths 30.1, 0.8, 31 make a triangle & why
Step-by-step explanation:
If this were to make a triangle, then 30.1 and 0.8 would be the shorter sides and 31 would be the longest side.
The sum of the lengths of the shorter sides is 30.1+0
8=30.9.
Since this is less than the length of the segment that would be the longest side, by the triangle inequality theorem, these side lengths would not make a triangle.
Given the equation 2x = 4y - 3 write another linear equation that would create a system that has the number of solutions listed
A . 0 Solutions
B . 1 Solution
C . Infinitely many solutions
Answer:
A. [tex]2x-4y=\pi[/tex]
B. [tex]x=1[/tex]
C. [tex]2x-4y=3[/tex]
Step-by-step explanation:
A. [tex]2x-4y=\pi[/tex]. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND [tex]\pi[/tex], or any number you like. But yesterday was 3/14 so let's pick a fun number!
B. [tex]x=1[/tex] Or [tex]y=1[/tex]. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind
C. [tex]2x-4y=3[/tex]. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.
The sum of two numbers is 64. The difference between the numbers is 14. Write a system
to find both numbers. Remember to show all work.
Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.

Answer:
5 37/45
Step-by-step explanation:
9 3/5 - 3 7/9
Find like terms
9 27/45 - 3 35/45
Subtract whole numbers
9 - 3 = 6
Subtract fractions
27/45 - 35/45 = -8/45
Subtract both of the numbers
6 - 8/45 = 5 37/45

c.

d.
-8°C, -5°F, 40°F, 10°C
ANSWER IS A
Answer:
a. -5°F, -8°C, 40°F, 10°C
Step-by-step explanation:
-17°C is when F = 0, so -8°C is way higher than -5°F. -8°C comes right after, and 40°F is a bit lower than 10°C. You can convert F to C is °F = (C * 9/5) + 32 and you can convert C to F with (F -32) x 5/9

start by diving 5 from each side so you are lrft with x on the left side, 40/5=8. now our equation is x=8 and that's the answer!
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
Given the following question:
[tex]5x=40[/tex]
When solving one-step equations, you need to remember we are trying to isolate the variable. In this case to isolate the variable we need to divide both sides by 5.
[tex]5x=40[/tex]
[tex]5x\div5=x[/tex]
[tex]40\div5=8[/tex]
[tex]x=8[/tex]
Which means the value of x will be "8."

Answer:
what are you looking for? are you looking for mean,median,and mode,
Step-by-step explanation:
If so here they are.
Mean=13.1
The mean is the average of the numbers in the data set.
Median=13
The median is the middle number from it being sorted least to greatest.
mode=10,18
The mode is the number that appears most in a data set or sometimes numbers like right now it's numbers,both 10 and 18 appear twice.
Range=15
The range is the highest number subtracted by the lowest number. so what is 19 - 4?it is 15.
minimum=4
The minimum in a data set is the lowest number.
Maximum=19
The maximum is the highest number in a data set.
IQR is 8 because the IQR is based on the lower quartile subtracted by the higher quartile so 18 - 10=8
