Divide 750 into the ratio 2:3
Answer:
300 : 450
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 = 5 parts
Divide 750 by 5 to find the value of one part of the ratio
750 ÷ 5 = 150 ← value of 1 part of the ratio , then
2 parts = 2 × 150 = 300
3 parts = 3 × 150 = 450
Then 750 in the ratio 2 : 3 = 300 : 450
The required answer is 750 in the ratio 2 : 3 = 300 : 450.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have to divide 750 into the ratio 2:3
The ratio is given in the question
⇒ 2:3
We can see that the sum of the parts of the given ratio as
⇒ 2 + 3 = 5 parts
Divide 750 by 5 to determine the value of one part of the ratio
So the value of 1st part of the ratio
⇒ 750 ÷ 5 = 150
Now, 2nd parts = 2 × 150 = 300
And, 3rd parts = 3 × 150 = 450
So, 750 in the ratio 2 : 3 = 300 : 450
Therefore, the required answer is 750 in the ratio 2 : 3 = 300 : 450.

Answers:
x = angle MLN = 35 degrees
angle FLJ = 55 degrees
=================================================
Explanation:
This problem is fairly tricky if you're not sure what to look for. A slight clue is that they've marked a red point that strangely doesn't have a label on it. It's a fairly small point but it's definitely there if you look closely. While this point's location isn't exactly what we want, we're fairly close. Start at point L and draw a ray through the center point P. Ray LP will intersect the circle at point A, as shown in the diagram below.
From here, draw segments FA and MA. Now notice that inscribed angle LMF = 55 and inscribed angle FAL both subtend the same arc. The term "subtend" basically means "cut off". This arc that the inscribed angles subtend is minor arc FL. A minor arc is where you travel the shorter path around the circle, which indicates its measure is less than 180 degrees.
Since inscribed angles LMF and FAL subtend the same minor arc, this makes the inscribed angles to be congruent.
In short: angle FAL is 55 degrees
----------------------
Segment LA goes through the center P. Through Thales theorem, we know that inscribed angle LFA is 90 degrees. Consequently, we can determine that inscribed angle FLA is 90-55 = 35 degrees.
Segment JL is tangent to the circle, meaning that angle ALJ is 90 degrees. So angle FLJ is 90-35 = 55 degrees.
It's not a coincidence that angle FLJ, angle FAL, and angle LMF are the same measure.
----------------------
We found that angle FAL was 55 degrees. Applying Thales theorem again shows that angle MAF is 90 degrees. Therefore, angle LAM is 90-55 = 35 degrees.
Focus now on triangle LMA. This is also a right triangle (Thales Theorem). The upper acute angle we found was angle LAM = 35, so the lower acute angle is ALM = 55.
Then we can find angle MLN = (angle ALN) - (angle ALM) = 90 - 55 = 35
In short, angle MLN = 35 degrees
Similar to the previous section, it is not a coincidence that angles LFM, LAM and MLN are the same measure.
------------------------
As an alternative, since we know angle FLJ = 55, and angle FLM is 90 degrees, this means...
(angle FLJ)+(angle FLM) + (angle MLN) = 180
55 + 90 + angle MLN = 180
145 + angle MLN = 180
angle MLN = 180 - 145
angle MLN = 35 degrees

Answer:
[tex]\angle NPM[/tex]
Step-by-step explanation:
Given
Circle of center P
Polygon JKLMN
Required
The central angle of JKLMN
From the question, we have that: the polygon and the circle have the same center (P).
This means that any central angle must pass through P
By this, PMN and NJK are incorrect
QPK divides the polygon and point Q is not on the vertex of the polygon.
By this, QPK is also incorrect
The final option NPM is correct, because P is at the center and points N and M are at the vertices of the polygon

What is m
A: 19°
B: 68°
C: 112°
Answer:
m<N=68
Step-by-step explanation:
opposite angles of the parallelogram are equal(or congruent):
4x+36=6x-2
6x-4x=36+2
2x=38
x=38/2=19
the sum of the angles of the parallelogram =360
4x+36=4(19)+36=112 angle P
6x-2=6(19)-2=112 angle M
let Q= N=x
2x+112+112=360
2x=360-224
2x=136
x=136/2=68

Suppose that a new employee starts working at $7.72 per hour and receives a 5% raise each year. After time t, in years, his hourly wage is given by the equation y=$7.72(1.05)t. Find the amount of time after which he will be earning $10.00 per hour.
After what amount of time will the employee be earning $10.00 per hour?
Answer:
substitute 10 for y (y=10) and solve for t
2.17
Step-by-step explanation:
I think the equation is written wrong because assuming that his wage increases at the end of each year, the beginning of the first year wages should be 7.72, not 0.
recommended correction
y=7.72 + (1.05)t

What is the perimeter of a quadrilateral with vertices at (5,2),
(10,2), (5,5), and (10,5)? PLZZ SHOW WORK AND RIGHT!
Answer:
16
Step-by-step explanation:
Draw a picture!
Length1 goes from (5, 2) to (10, 2)
since the y coordinate is the same
L1 = (10 - 5) = 5
Length2 goes from (5, 5) to (10, 5)
since the y coordinate is the same
L2 = (10 - 5) = 5
Width1 goes from (5, 2) to (5, 5)
since the x coordinate is the same
W1 = (5 - 2) = 3
Width2 goes from (10, 2) to (10, 5)
since the x coordinate is the same
W2 = (5 - 2) = 3
-----------------------
Perimeter
p = 5 + 5 + 3 + 3
p = 16
The perimeter of quadrilateral is 16 units.
What is quadrilateral?A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilateral interior angle sums are always equal to 360 degrees.
Given coordinates,
(5,2), (10,2), (5,5), and (10,5)
let A, B, C, and D be the points of coordinates (5,2), (10,2), (5,5), and (10,5) respectively.
Length1 goes from (5, 2) to (10, 2)
since the y coordinate is the same
AB = (10 - 5) = 5
Length2 goes from (5, 5) to (10, 5)
since the y coordinate is the same
BC = (10 - 5) = 5
Width1 goes from (5, 2) to (5, 5)
since the x coordinate is the same
CD = (5 - 2) = 3
Width2 goes from (10, 2) to (10, 5)
since the x coordinate is the same
DA = (5 - 2) = 3
perimeter = sum of all sides
p = 5 + 5 + 3 + 3 = 16 units
Hence the perimeter is 16 units.
