What is x if 2784 = 36x?
Answers
Answer:
77 1/3
Step-by-step explanation:
to get x you have to divide both sides by 36
2784=36x
x=77 1/3
you can also use an algebra calculator for it
Answer:
77.333
Step-by-step explanation:
So we are given the equation
2784 = 36x
But we need to find the value of just x. So if 36 x = 2784:
2784/36 = x
How did we do this? Well, we divided each side of the equation by 36, which gives us the amazing value of just x.
Solve the equation
77.333 = x
Now, lets check our work:
77.333 x 36 = 2783.88
This is the closest I believe we can get.

The image of the point (-5, 1) under a translation is (-6,3). Find the
coordinates of the image of the point (2, -3) under the same translation.
Answers
Answer:
The coordinates are (1,-1).
Step-by-step explanation:
The image of the point (-5, 1) under a translation is (-6,3).
Point x was -5 and now is -6, and y was 1 and now is 3. Thus, the transaction rule is:
(x,y) -> (x - 1, y + 2)
Find the coordinates of the image of the point (2, -3) under the same translation.
(2,-3) -> (2-1, -3 + 2) = (1,-1)
The coordinates are (1,-1).

Two trains, Train A and Train B, weigh a total of 351 tons. Train A is heavier than Train B. The difference of their weights is 181 tons. What is the weight of each train?
Answers
Answer:
Train A is 266 and Train B is 85
Step-by-step explanation:
If the difference is 181 tons, then subtract the difference to get double the weight of the lightest train.
351 - 181 = 170
170 ÷ 2 = 85
If B is the lightest, B is 85.
For A, either add the difference back or subtract 85 from 351.
85 + 181 = 351 - 85 = 266

Answers
Answer:
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8
Step-by-step explanation:
To find the equation of the line in the slope-intercept form, y = mx + b, we have to determine the value of:
Slope (m) = change in y/change in x
y-intercept (b) = the y-coordinate of the point where the y-axis is intercepted by the line
Using the two points indicated in the line, (-7, -3) and (-2, 4),
Slope (m) = (4 - (-3))/(-2 - (-7)) = 7/5
m = ⁷/5
To find b, substitute m = ⁷/5 and (x, y) = (-2, 4) into y = mx + b
4 = ⁷/5(-2) + b
4 = -14/5 + b
4 + 14/5 = b
(20 + 14)/5 = b
34/5 = b
b = 34/5
To write the equation, substitute m = ⁷/5 and b = 34/5 into y = mx + b
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8

∠GAF ≌ ∠TAE.
∠TAE and ∠FAH are complementary.
∠TAF is obtuse.
Answers
Answer:
Statement 3
Step-by-step explanation:
∠GAF ≅ ∠TAE
Since, there is no relation between these angles,
Therefore, statement is False.
∠TAE and ∠FAH are complementary.
If the sum of the two angles is 90°, pair of angles is said to be complimentary angles.
Therefore, this statement is False.
∠TAF is obtuse.
Measure of obtuse angle is more than 90°
From the given picture, measure of ∠TAF = m∠TAH + m∠HAF
= 90° + 50°
= 140°
Here, m∠TAF > 90°
Therefore, ∠TAF is an obtuse angle.
Statement (3) is the correct statement.

Answer:
A quick hack is often to partially express some function in terms of a Taylor approximation about x0, since higher order terms of x go to zero if we are considering limits for (x−x0)→0. To really answer your question we need to know what the original question was, that is, about which point do you want the expansion? Let us assume around 0. Then we have the Maclaurin series:
cos(x)=1−12x2+O(x4)
You can add more terms if you need to. Now we write:
ln(1+(−12x2))=…

To ease congestion in a downtown area, city planners are considering a plan to widen a major thoroughfare from
two driving lanes to three driving lanes. This plan would require closing a section of downtown streets as the work
begins. In order to assess public support for the plan, city planners provided a phone number to residents that could
be used to register opinion for or against the plan. In total, 267 calls were received, with only 24% supporting it.
Which statement describes the most likely type of bias in this setting?
This is nonresponse bias because many residents may choose to not participate.
This is question wording bias because the phrasing of the plan may have confused some residents.
This is voluntary response bias because residents could choose to call and register their opinion.

The volume
The volume (V) is calculated as:

Hello there I hope you are having a great day :) You Question A plumber can complete a job in 2 hours. If an apprentice helps, it takes only 1 1/3 hours. How long would it take the apprentice working alone?
(1 1/3) / 2 + (1 1/2) / a = 1
(4/3)a + (4/3)2 = 2a multiply both sides by 2a
(4/3)2 = (2/3)a subtract (4/3)a from both sides
8/3 = 2a/3 simplify
8 = 2a
4 = a
