Answer:
300 g
Step-by-step explanation:
weight of a can of biscuits= (23- 0.5)/15= 1.5 kg
weight of 8 cans= 1.5 * 8= 12 kg
mass of the empty box Q= 12.3- 12= 0.3 kg= 300 g
Answer:
300 g or 0.3 kg
Step-by-step explanation:
23 kg - 500g = 22.5 kg
each can of biscuits weighs 22.5 ÷ 15 = 1.5 kg
if the box Q weighs 12.3kg when there's 8 box of biscuits then
8 × 1.5 = 12 kg is the weight of biscuits and the remaining 300 g is box Q's weight
If y(x) = 2x^2 +sqr/5(x-2), complete the following statement:
f(6) =
Answer:
Step-by-step explanation:
Just plug in 6 as x.
[tex]f(6)=2(6)^2+\sqrt{5} *(6-2) \\or\\f(6)=2(6)^2+\sqrt{5(6-2)}[/tex]
Depending on how the equation is written (I got confused so I gave both answers of what I thought both versions were) this is the answer.
[tex]72+4\sqrt{5} =2(6)^2+\sqrt{5} *(6-2) \\or\\72+2\sqrt{5} =2(6)^2+\sqrt{5(6-2)}[/tex]
Can someone please explain to me how to find y=Mx+b? We’ve learned this a long time ago and I kinda forgot .. can’t find a solution anywhere else :/
Answer:
y = mx + b equals y = the slope of the line(x) + the y-intercept
First find the slope of the line using rise/run, which is 12/-2 so the slope is -6
To find the y-intercept, you need to look for the point where x = 0 (or the point that lies on the y-axis), which is when y = -4 so the equation is:
y = -6x - 4
I can’t figure out the answer to this, does anybody know?
Answer:
Option (2).
Step-by-step explanation:
Let f(x) and g(x) are the two functions with domain A and B.
Then (fg)(x) will be the function with domain A∩B
(fg)(x) = f(x)g(x) Domain : A∩B
In this question two functions are,
c(x) = [tex]\frac{5}{(x-2)}[/tex] and d(x) = (x + 3)
Domain : (x - 2) > 0 ⇒ x > 2
and (x - 2) < 0 ⇒ x < 2
Or domain of (cd)(x) will be C = (-∞, 2)∪(2, ∞).
Similarly, d(x) = x + 3
Domain : All real numbers
: D = (-∞, ∞)
(cd)(x) = c(x)d(x)
= [tex]\frac{5}{(x-2)}\times (x+3)[/tex]
Domain of (cd)(x) will be,
Domain : C∩D = (-∞, 2)∪(2, ∞) ∩ (-∞, ∞)
: (-∞, 2) ∩ (2, ∞)
Therefore, domain of (cd)(x) will be all real values except 2.
Option (2) will be the answer.
It is worked out that if 3 ladles full of soup are given to each person,
150 people can be fed.
The customers have complained in the past that the portions are too small.
The cook decides to give 5 ladles full of soup to each person.
How many people can now be fed soup?
Answer:
it is worked out that if 5 ladles full soup are given to each person 300 at a time
Answer:
90 people
Step-by-step explanation:
Let's find the total number of ladels of soup.
1 person ----- 3 ladles
150 people ----- 3 ×150= 450 ladles
The amount of soup cooked does not change. Since now more soup is given to each person, the number of customers fed would decrease.
Number of people fed
= 450 ÷5
= 90

What are the solutions of x2 +6x-6= 10?
O x=-11 or x=1
O X=-11 or X=-1
O X=-8 or X=-2
O X=-8 or X= 2
Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x-6= 10
Subtract 10 from each side
x^2 +6x-6-10= 10-10
x^2 +6x-16 = 0
What 2 number multiply to -16 and add to 6
8 * -2 = -16
8 -2 = 6
(x+8) (x-2)=0
Using the zero product property
x+8=0 x-2=0
x= -8 x=2

Answer:
x = -5/3 and y = -1
Step-by-step explanation:
write it as a system and simplify
-4 for the first equation (in the photo but when putting it into a system of equations it would be 2nd)
So it's
-3x-2y=7
-3x+2y=3
then it's -6x=10
then divide oth sides by -6 to get x then plug that into whatever equation and solve for y.
i hope this is right and helps

Answer:
(-5,4)
Step-by-step explanation:
A: (5,4)
Reflect it across the y axis would mean you negate the x value
So if you reflect it across the y axis, 5 would become -5
Answer:
B
(-5,4)
Step-by-step explanation:
square 1 (+,+) square 2 (-,+) square 3 (-,-) square 4 (+,-) Find the coordinates is (5,4) but reflect the y-axis so it goes to square 2 where the x-axis turns in to a negative

According to a survey done at your school, about 42% of all the female students participate in 2 sport seasons. You randomly ask 5 female students at your school how many sport seasons they participate in. What is the probability that at least 3 of the 5 female students surveyed participate in 2 sport seasons? Show your work.
Answer: 0.353
Step-by-step explanation:
We know that 42% of all the female students participate in 2 sports this season. (58% is the percent that did not)
This means that if we select a random student, there is a 0.42 probability that the student did participate in 2 sports this season.
Other thing that i will use is that, if we have a group of N objects, and we want to create a group of K objects out of the N, the number of combinations is:
[tex]c = \frac{N!}{(N - K)!*K!}[/tex]
Now, out of 5, we want to find the proability that, at least 3 of them, did participate in at least 2 sports this season.
The probability that all 5 of them participated, is equal to the product of the individual probabilities. (so N = 5, and K = 5)
P = (0.42^5)*1 = 0.013
Now, if only 4 of them did participate (N = 5, k = 4), the probability is equal to:
P = (0.42^4)*(0.58)*5!/4! = (0.42^4)*(0.58)*5 = 0.09
The probability for only 3 is: (N = 5 and K = 3)
P = (0.42^3)*(0.58^2)*5!/(3!*2!) = (0.42^3)*(0.58^2)*(5*4/2) = 0.25
Then the total probability is:
P = 0.013 + 0.09 + 0.25 = 0.353
PLzz HeLP Moi x(y-xy), where x= -5 and y= -2
2) Rearrange the Pythagorean Theorem to solve first for c and then y.
Answer:
[tex]x=z-\sqrt{-y} , or, x^2=z^2-y^2\\y=z-\sqrt{-x}, or, y^2=z^2-x^2[/tex]
Step-by-step explanation:
I can't do much except put the Pythagorean theorem in terms of y or x.
All I did was isolate x or y by subtracting the, x or y variable from each side.
[tex]-(y^2)+x^2 +y^2=z^2-(x^2)\\-(y^2)+x^2 +y^2=z^2-(y^2)[/tex]
Which tuns it into:
[tex]x^2=z^2-y^2\\y^2=z^2-x^2[/tex]
And I isolated further by squaring each side, but squaring negative number is difficult and causes imaginary numbers so I just think it should stay as all of them to the power of two.
What is the range of the set of data used to create this box plot ?

What is the nth rule of the quadratic sequence 4,15,30,49,72,99,130
Answer:
2(n²)+5n-3
Step-by-step explanation:
4,15,30,49,72,99,130
1st you find the difference between the numbers: (e.g. difference between 4 and 15 is 11) 11,15,19,23,27,31 Then you find the second difference between them. 4,4,4,4,4,4
If you divide the second difference by 2, you will get the value of a. 4 ÷ 2 = 2
So the first term of the nth term is 2n²
Then you have to do what do you do to get from 2n² to 4,15,30,49,72,99,130
Imagine that you are given two linear equations in slope-intercept form. You
notice that the slopes are the same, but the yintercepts are different. How
many solutions would you expect for this system of equations?
A.0
B.cannot be determined
C.1
D.infinitely many
Answer:
A. 0
Step-by-step explanation:
y= mx+b
with same slope, m= same for both
if b is different, then the lines are parallel
so no solution, option A. 0

Please answer the 16th qs
Answer:
p = 13
Step-by-step explanation:
When a polynomial f(x) is divided by (x + h) then the remainder is f(- h)
Here both polynomials are divided by (x + 1)
Evaluate them both for x = - 1
3(- 1)³ - 5(- 1)² - 4(- 1) + p, that is
- 3 - 5 + 4 + p
= p - 4 → A
6(- 1)³ + p(- 1)² + 9(- 1) + 5, that is
- 6 + p - 9 + 5
= p - 10 → B
Given that A = 3B, then
p - 4 = 3(p - 10)
p - 4 = 3p - 30 ( subtract 3p from both sides )
- 2p - 4 = - 30 ( add 4 to both sides )
- 2p = - 26 ( divide both sides by - 2 )
p = 13
