Answer:
150120.83 ; 40 ; 1800
Step-by-step explanation:
Amount of share per person = x
Number of persons = y
x = k/y
k = constant of proportionality
k = xy
257,350 * 7 = 1801450
k = 1801450
If there are 12 persons ; y = 12
x = k/y
x = 1801450 / 12
x = 150120.83
2.) weight on Mars = m
Weight in earth = e
m α e
m = ke
48 = 120k
k = 48 / 120
k = 0.4
m = 0.4 * 100
m = 40
3.)
I α pt
I = kpt
600 = k * 10000 * 2
600 = 20000k
k = 600/20000
k = 0.03
I = 0.03 * 15000 * 4
I = 1800

slope is 2/3 y- intercept is -2
Answer:
y = (2/3)x - 2
Step-by-step explanation:
The equation of this line is y = (2/3)x - 2, where m is the given slope and -2 is the given y-intercept. We need only plug in the given values for m and b.
Answer:
[tex]y = \frac{2}{3} x -2[/tex]
Step-by-step explanation:
This is the slope-intercept form. The slope-intercept form is written as y = mx + b where m is the slope and b is the y-intercept. The y and x stay as they are.

HOW DO YOU FIND ANGLE 1
Answer:
If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.
Step-by-step explanation:
a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.
Dexter has worked out 3/5 x 8 here is his working. explain the mistake he has made.
Answer:
He multiplyed 3x8 and 5x8 when it should be 3x8 and 5x1 because you but 1 under the 8 to make it into a fraction.
Step-by-step explanation:
I’ve been stuck on this for a few minutes. I’m not really sure what to do..
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

Two angles are supplementary. The measure of one angle is 5 greater than 40% of the other. Find the measures of both angles.
Answer:
Step-by-step explanation:
0.40beta%2Bbeta=180-5
1.40beta=175
beta=175%2F1.40
highlight%28beta=125%29�
then alpha%2B125=180 =>alpha=180-125 =>highlight%28alpha=55%29
The required values of angles are 125 and 55.
What is angle ?When two straight lines come together at a point, they produce an angle, which is represented by the symbol.
Given that,
Two angles are supplementary to each other.
Let angles are α and β.
According to given condition,
α + β = 180 (1)
Also, the measure of one angle α is 5 greater than 40% of the other.
α = 0.4 β + 5 (2)
Substitute the value of α in equation (1),
0.4 β + 5 + β = 180
1.4 β = 175
β = 175 / 1.4 = 125
The value of α =0.4 x 125 + 5 = 50 + 5 = 55
The value of angle α and β are 125 and 55.

To find:
The measure of angle A to the nearest degree.
Solution:
We have,
[tex]\cos \angle A=\dfrac{342}{1000}[/tex]
It can be written as
[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]
[tex]\angle A=70.00123^\circ[/tex]
[tex]\angle A=70^\circ[/tex]
