Answer:
27/5
Step-by-step explanation:
5 wholes=5/1
convert 5/1 into fifths, which is 25/5
add 25/5 to 2/5 to get your answer, 27/5
For any nonnegative real number.
Answer:
A
Step-by-step explanation:
We know that [tex]\sqrt{b}=b^{1/2}[/tex].
We also know that [tex](a^b)^c=a^{bc}[/tex].
We can combine these facts to get [tex](\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b[/tex].
So, the answer is [tex]\boxed{A}[/tex] and we're done!
Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.
The teacher-student ratio at Dunn Middle School is 1 to 23. If there are 966 students, how many
teachers are there?
Answer:
42 teachers
Explanation:
Teacher to student ratio is 1:23
If there are 966 students, then divide by 23 to get how many teachers their are.
966/23=42
A 145-inch board is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
i need to figure this out in the next 20 mins cause i have to turn this in to get a good grade please...
Answer:
4x + x = 145, x=29 (shorter piece)
5x=145
x=145/5 = 29
Step-by-step explanation:
Calculate the vertices of the figure given by A (1, 3), B (4, 7), and C(6, 6) after being
translated using the rule (x, y) > (x + 2, y + 3).
The new points are:
A’
B’
C’
Answer:
see explanation
Step-by-step explanation:
The rule (x, y ) → (x + 2, y + 3 )
Means add 2 to the original x- coordinate and add 3 to the original y- coordinate, that is
A (1, 3 ) → A' (1 + 2, 3 + 3 ) → A' (3, 6 )
B (4, 7 ) → B' (4 + 2, 7 + 3 ) → B' (6, 10 )
C (6, 6 ) → C' (6 + 2, 6 + 3 ) → C' (8, 9 )
I HOPE IT WILL HELP YOU.
Thank you.

solve 7 √ 3 + 2 √ 9 and explain whether the answer is rational or irrational
Answer:
Option D. is correct.
Step-by-step explanation:
Let us assume that x = seven square root three plus two square root nine
i.e. x = 7√3 + 2√9
⇒ x = 7√3 + 2 × 3 {Since 9 = 3²}
⇒ x = 7√3 + 6
Here, 7√3 is an irrational number and 6 is a rational number.
The answer is seven square root of three plus six is irrational because the sum of a rational number and an irrational number is an irrational number.
Therefore, option D. is correct.
The correct answer is 7√3 + 6 is irrational because the sum of a rational number and an irrational number is an irrational number.
What are rational numbers, and irrational numbers?Rational numbers are numbers which can be written in the form of [tex]\dfrac{a}{b}[/tex] where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.
Irrational numbers are those real numbers which are not rational numbers.
Assume that x be the seven square root three plus two square root nine ;
i.e. x = 7√3 + 2√9
Now
⇒ x = 7√3 + 2 × 3 {Since 9 = 3²}
x = 7√3 + 6
Here, we can see that 7√3 is an irrational number and 6 is a rational number.
The correct answer is seven square root of three plus six is irrational because the sum of a rational number and an irrational number is an irrational number.
Therefore, option D is correct.

What are the coordinates of the point on the directed line segment from (−8,5) to (4,−3) that partitions the segment into a ratio of 5 to 3?
Answer:
(-0.5, 0)Step-by-step explanation:
Directed line segment from (−8,5) to (4,−3).
Ratio is 5/3.
The required coordinates are:
x = -8 + 5/8*(4 - (-8)) = -8 + 5/8(12) = -8 + 7.5 = -0.5y = 5 + 5/8*(-3 - 5) = 5 + 5/8(-8) = 5 - 5 = 0please help me anyone !!!!
Answer:
If you rotate the triangles so that they look the same, one side of both of them are labeled. This gives you the fraction 9/12, or 3/4. The smaller triangle is 3/4th of the larger one. If the larger triangle has 4 on one side, then let's make the equation 3/4 = y/4. The length of y is 3. :)

A film ends at 1.05 a.m and lasts for 1 hour 45 min. At what time does the film start?
u will have to add the two
1hr 45mins + 1:05
remember add hrs to hrs and minutes to minutes
1+1 =2
45+5=50
which means the movie started at 2:50 am
and to verify ur answer subtract 2:50 from 1:05
= 1hrs 45 mins

If -13(q+4) is equal to 7q+16 what’s is q
Answer:
q = - 3.4
Step-by-step explanation:
- 13(q + 4) = 7q + 16 ← distribute parenthesis on left side
- 13q - 52 = 7q + 16 ( subtract 7q from both sides )
- 20q - 52 = 16 ( add 52 to both sides )
- 20q = 68 ( divide both sides by - 20 )
q = - 3.4

Select all that apply.
The y-interceptis (0.-2).
The x-interceptis (0,5).
The domain of the function is (-3.3)
The domain of the function is all real numbers.
Answer:
The domain of the function is all real numbers.
Step-by-step explanation:
The answer is not A because the y-axis is the vertical (straight up and down) axis, and it crosses of that at positive 5.
The answer is not B because the x-axis is the horizontal axis, and it crosses that at negative 2.
Don't let them confuse you by saying the intercepts of one is the other!
It is also not C because the answer is D, we know this because the arrows at each end of the arrow signify that the line keeps going infinitely in each direction.

38=1/8k+47
Find the value of k
Answer:
[tex]k=-72[/tex]
Step-by-step explanation:
[tex]38=\frac{1}{8} k+47[/tex]
Switching the sides of the equation isn't required, but it helps to reduce confusion.
[tex]\frac{1}{8}k+47=38[/tex]
Since there is a positive 7, we are going to do the opposite operation, which is addition.
[tex]\frac{1}{8}k+47-47=38\\\text\:\:\:\:\:\:-47\:\:\:\:\:\:\:\:\:-47[/tex]
Simplify
+47 - 47 will cancel each other out, so we are left with:
[tex]\frac{1}{8}k=-9[/tex]
Now, multiply 8 to both sides, since the equation gives us 1 divided 8, so the opposite operation of division is multiplication.
[tex]8\cdot \frac{1}{8}k=8\left(-9\right)[/tex]
On the right side, we have the same thing as [tex]\frac{8}{1} \cdot \frac{1}{8}[/tex], so 8 we can cancel the equation on the right side since they are both the same number.
On the left, we have [tex]8\left(-9\right)[/tex], which is -72.
Therefore, [tex]k=-72[/tex].
