Answer:
5 oranges in 12 minutes
Step-by-step explanation:
[tex]125 \div 5 = 25[/tex]
[tex]25 \div 60 = 0.41[/tex]
[tex]0.41 \times 12 = 5[/tex]
what i did here was I took the original amount (125), divided it by 5 which is 25 oranges per hour
1 hr = 60 mins
then I divided 25 oranges by 60 mins, then times it by 12 to get 5 around 5 oranges in 12 minutes.
Answer:
[tex]\boxed {\tt 5 \ oranges}[/tex]
Step-by-step explanation:
Let's set up a proportion.
[tex]\frac{oranges}{minutes} =\frac{oranges}{minutes}[/tex]
He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}[/tex]
We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}[/tex]
[tex]\frac{125 \ }{300 \ }=\frac{x \ }{12 }[/tex]
Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.
[tex]12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12[/tex]
[tex]12*\frac{125 \ }{300 \ }=x[/tex]
[tex]12*0.416666667=x[/tex]
[tex]5=x[/tex]
Rob can peel 5 oranges in 12 minutes.
Three students were given the expression shown and were asked to take a
common factor out of two of the terms.
Use the drop-down menus to complete the statements about whether each
student's answer is an equivalent expression. Then choose an expression
that is equivalent
4 - 9x + 21
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
Let us analyze each of the students expression and determine the correct one if there are any.
Chang expression after factoring: 4-3(3x+7)
In order to know whether chang's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4-3(3x+7)
Open the parenthesis
= 4 - 3(3x)-3(7)
= 4 - 9x - 21
This shows that Chand expression is wrong.
Hence Chang expression is not an equivalent expression because when -3 is factored out from the bracket, it supposed to leave a negative sign instead of positive.
Benjamin expression after factoring: 4+3(3x+7)
In order to know whether Benjamin's factorization is similar to the expression, we will expand and compare with the given expression as shown;
= 4+3(3x+7)
Open the parenthesis
= 4 + 3(3x)+3(7)
= 4 +9x + 21
This shows that Benjamin expression is wrong.
Hence Benjamin expression is not an equivalent expression because the positive values within the expression is supposed to be negative sign instead
Habib expression after factoring: 4+12x
The equation is obviously wrong and not an equivalent expression because the constant value 21 does not have a variable x and cannot be added to -9x according to what Habib did.
Given the expression
4 - 9x + 21
The correct simplification of the expression is as shown;
4 - 3(3x - 7)
Note that when -3 is factored out, the sign inside the parenthesis also changes
I need help with the first question
Answer:
Subtract 2k from both sides.
4k−3−2k=2k+5−2k
2k−3=5
Add 3 to both sides.
2k−3+3=5+3
2k=8
Divide both sides by 2.
2k /2 =8/2
k=4

Describe the end behavior of the graph f(x) using limits.
Answer:
um
Step-by-step explanation:
The end behavior of the graph f(x) using limits are
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
Option B is the correct answer.
We have,
From the graph,
As the x-value increases, the function y-values goes to -∞.
As the x-value decreases, the function y-values goes to -∞.
Now,
f(x) is the y-value.
The end behavior of the graph f(x) using limits can be represented as,
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]
Thus,
The end behavior of the graph f(x) using limits are
[tex]\lim_{x \to -\infty} f(x) = -\infty[/tex]
and
[tex]\lim_{x \to \infty} f(x) = -\infty[/tex]

Gary applied the distributive property using the greatest common factor to determine the expression that is equivalent to 66 + 36. His work is shown below. Factors of 66: 1, 2, 3, 6, 11, 22, 33, 66 Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36 66 + 36 = 3 (22 + 12)
Step-by-step explanation:
Factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
GCF (greatest common factor) = 6
Gary applied the distributive property using the greatest common factor to determine the expression that is equivalent to 66 + 36. He wrote it as :
66 + 36 = 3 (22 + 12)
But he is wrong. He multiplied (22+12) by 3 which is wrong. The correct step should be :
66 + 36 = 6 (11+ 6)
= 6(17)
= 102
Hence, this is the required solution.

4(2q – 3) = 8q-12
Pls solve and show steps
Answer:
LHS = RHS = -12
Step-by-step explanation:
=> 4(2q - 3 ) = 8q - 12.
=> 8q - 12 = 8q - 12 .
=> 8q - 8q - 12 = -12 .
=> -12 = -12 .
Hence LHS = RHS .
[tex]4(2q - 3) = 8q - 12[/tex]
[tex]8q - 12 = 8q - 12[/tex]
[tex]8q + - 12 = 8q + - 12[/tex]
[tex] - 12 - 8q = - 12 - 8q[/tex]
[tex] - 12 = - 12[/tex]
[tex] - 12 + 12 = - 12 + 12[/tex]
[tex]0 = 0[/tex]
By the above equation , we can conclude that any real number can be placed in the place of q to make the left hand side of the equation become equal to the right hand side of the equation .
Therefore , any real number ( integer , fraction and rational number ) can be placed in the place of q .
Last year, 320 students were members of Pine Hill Middle School clubs. This year, there was a 20% increase in memberships. How many students are members this year?
Answer:
384
Step-by-step explanation:
No. of students in the club last year = 320
No. of students in the club this year increased by 20%
To find the actual increase, 20% is multiplied by the number of students in the club last year which is 320 and to find the number of students in the club this year add the answer to 320 (the number of students in the club last year)
That is,
= 20% * 320
= 20/100 * 320
= 64
Finding the number of students in the club this year
320 + 64 = 384 students
NOTE : Increase means addition that is why the number of students in the club last year is added to the actual increase
Find the value of d so the line that passes through (a,b) and (c,d) has a slope of 12.
Answer:
d = 12c-12a+b
Step-by-step explanation:
The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2)is expressed as:
m = y2-y1/x2-x1
Given the coordinates (a,b) and (c,d) and slope m = 12
Substitute into the formula as shown:
m = d-b/c-a
12 = d-b/c-a
Make d the subject of the formula:
12 = d-b/c-a
cross multiply
12(c-a) = d-b
12c-12a = d-b
add b to both sides
12c-12a + b = d-b+b
12c-12a + b = d
Hence d = 12c-12a+b

If two angles are adjacent, then they have a common ray
Answer:
There are some special relationships between "pairs" of angles. Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) ... A Linear Pair is two adjacent angles whose non-common sides form opposite rays.
