if 4/3 x 3/4 = 5k, then k = ?
Answer:
k= 1 /15 x^3
Step-by-step explanation:
4/3 x 3/4 = 5k
5k= 1 /3 x^3
k= 1 /15 x^3
The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.
To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.
Multiplying the fractions on the left side:
(4/3) × (3/4) = 12/12 = 1
Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.
Dividing both sides of the equation by 5:
1/5 = k
Hence, the value of k in the given equation is 1/5.

The correct question is as follows:
If (4/3) × (3/4) = 5k, then find the value of k.

YO NEED SOME HELP ON THIS END OF GRADE SOON!!
Answer: b
Step-by-step explanation:
Cuz is a negative get in absolute value it always comes out positive
And it says below 0-9=-9
Answer:
BStep-by-step explanation:
__________________________________________________________
B is the answer because,
if the negative sign is not inside the "brackets," then the number will still be negative.
__________________________________________________________
But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.
__________________________________________________________
Here are the reasons why the rest are wrong.
__________________________________________________________
A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.
__________________________________________________________
C is not correct because it is plainly not correct in itself.
__________________________________________________________
D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

Hope this helps! <3

Given congruent triangles ΔABC ≅ΔDEF where AB = 11, BC = 5, and DE = 6x-7. Find the value of x.
Answer: Congruent angles are angles that have the same measure. ... y = 67 x = 180 – 67 = 113. 2. x = ______ y = ______. 3x – 5 = 127. +5 +5. 3x = 132 ... Find the measure of the angle and give the reason for knowing it. ... Solve for the unknown values: ... 2) AD. 3) AB. 4) BC. 24. In ΔABC, If CA ≅ CB and m∠A = 50, find the m∠B.
Answer:
x = 3
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are congruent, that is
DE = AB , substitute values
6x - 7 = 11 ( add 7 to both sides )
6x = 18 ( divide both sides by 6 )
x = 3
List the sides in order from shortest to longest. The diagram is not to scale.

Please help me answer this :) and explain how you got your answer ! ( will give brainslt )
Answer: y = - 0.4 x - 4.5
Step-by-step explanation:
Equation y=mx+b
m is the slope
x is *ANY* x coordinate
y is *ANY* y coordinate
b is y intercept or WHERE the point is on the Y AXIS
Lets look at the given:
Slope (m) is -2/5
Passes through point 15, -9/2
As you can see, the point goes through the Y axis at (-9/2)
Our equation is y = - 0.4 x - 4.5
Can someone help me please
There are two approaches to this question.
Approach 1:
We can compute the slope of a line by calculating its mean variation, the rise over run. Mathematicaly:
[tex]a=\frac{\Delta y}{\Delta x}[/tex]
The two points we have are [tex]P1 = (1,3)[/tex] and[tex]P2 = (4,3)[/tex]. Plugging the values into the expression we get
[tex]a=\frac{3-3}{4-1} \\a=0[/tex]
Therefore, the slope of the line is zero.
Approach 2:
The slope of the line is given by the angle [tex]\alpha[/tex] it makes with the X axis, in other words,
[tex]a = tan(\alpha)[/tex]
Note that the angle the line makes is exaclty zero. Therefore:
[tex]a= tan(0)\\a=0[/tex]
Again, we get that the slope of the line is zero.
In general, the slope of any horizontal line will always be zero.

Online photos: A poll surveyed internet users and found that of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.
1. State the appropriate null and alternate hypotheses.
2. Compute the P-value.
Complete question :
Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.
1. State the appropriate null and alternate hypotheses.
2. Compute the P-value.
Answer:
H0 : p = 0.5
H1 : p < 0.5
P value = 0.200454
Step-by-step explanation:
Given that :
Claim : Less than half internet users have posted photos or videos online.
Sample Proportion (p) = 865 / 1765 = 0.4900
The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.
The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;
P = 0.5
q = 1 - 0.5 = 0.5
The test statistic :
Z = p - p0 / sqrt(p0 * (q/n))
Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))
Z = - 0.01 / sqrt(0.5 *0.0002832)
Z = - 0.01 / sqrt(0.0001416)
Z = - 0.01 / 0.0119013
Z = - 0.8402443
The corresponding p value from the z statistic score at α = 0.01
= 0.200454

Solve the equation
1/3(9k+3)=-2(k-8)
Answer:
k=3
Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
step 1: simplify both sides of the equation
([tex]\frac{1}{3}[/tex]) (9k) + ([tex]\frac{1}{3}[/tex]) (3) = (-2) (k) + (-2) (-8) (distribute)
3k + 1 = -2k +16
step 2: add 2k to both sides
3k + 1 + 2k =-2k + 16 + 2k
5k + 1 = 16
step 3: subtract 1 from both sides
5k + 1 - 1 = 16 - 1
5k = 15
step 4: divide both sides by 5
[tex]\frac{5k}{5}[/tex] = [tex]\frac{15}{5}[/tex]
k = 3

At a large university, 434 freshmen, 883 sophomores, and 43 juniors are enrolled in an introductory algorithms course. How many sections of this course need to be scheduled to accommodate all these students if each section contains 34 students?
Answer: it will take 40 sections the course to accommodate all the students
Step-by-step explanation:
Given that;
434 freshmen, 883 sophomores and 43 juniors are enrolled
total number of students enrolled = (434 + 883 + 43) = 1360
number of student in one section = 34
now
number of sections of an introductory algorithms course needed to be scheduled to accommodate all these students will be;
Total number of section = total number of students enrolled / number of student in one section
so we substitute
Total number of section = 1360 / 34
Total number of section = 40
Therefore it will take 40 sections the course to accommodate all the students
