Mary, Hans, and Alan have a total of $54 in their wallets. Mary has $10 more than Hans. Alan has 2 times what Mary has. How much do they have in their
wallets
Answers
Answer: $95
Step-by-step explanation:
Let's say Maria is M, Hans is H and Alan is A. Maria has M amount of money. If Hans has 10 more than Maria, he has M+10. If Alan has 3 times what Hans has and Hans has (M+10), then Alan has 3(M+10) which is 3M+30. Altogether they have 95 dollars. So we will add up what they have and set it equal to 95. M+10+M+30+3M=95. That simplifies to 5M+40=95 and 5M=55. Therefore, Maria has 11 dollars. Hans has 10+11=21, and Alan has 3(21)=63. 11+21+63=95
He used the following steps:12/1 x 3/4=36/4

Answers
First step is to find the gradient.
m = (y2-y1)/(x2-x1)
= ( 5- -8)/(8-4) = 13/4
We have y = (13/4)x + c
Now we replace one of the coordinates to find c. Let’s replace (4,-8)
We have: -8 = (13/4)*4 + c
-8=13+c
c=-8-13= -21
Therefore, equation of line is:
y = (13/4)x - 21

Step-by-step explanation:
Bascially when your solving for x intercept, substitute 0 for y, then for this equation u get 0=5x-2, which is equal to 5x=2, so the x intercept is 2/5. You do the same thing for y intercept, so substitute 0 for x this time, then you'd get y=-2.

A circle with a radius of 15 yards contains a sector with an area of 609 yde. Find the measure of
the central angle of the sector in both radians and degrees.
(HELP PLEASE)(WILL GIVE BRAINLIEST)
Answers
Answer: 310.3° or 5.41 radians.
Step-by-step explanation:
The area of a circle of radius R is calculated as:
A = pi*R^2
Now, if we have a sector of an angle θ degrees, the area of that sector is:
A = (θ/360°)*pi*R^2
In this case, we know that:
R = 15yd
And the area of the sector is 609 yd^2
Then we can replace these two values in the equation to get:
609yd^2 =(θ/360°)*3.14*(15yd)^2
(609yd^2)*360°/(3.14*(15yd)^2) = θ = 310.3°
And we want the angle also in radians.
We know that:
3.14 rad = 180°
(3.14 rad/180°) = 1
Then:
310.3° = 310.3°*(3.14 rad/180°) = (310.3°/180°)*3.14 rad = 5.41 radians.
The measure of the central angle in degrees and radians are 310.32° and 5.42 rad respectively
Sector of a circle:Area = ∅/360 × πr²where
r = radius
∅ = central angles
Therefore,
609 = ∅ / 360 × 3.14 × 15²
609 = 706.5∅ / 360
219240 = 706.5∅
∅ = 219240 / 706.5
∅ = 310.318471338
∅ = 310.32°
1° = 0.0174533 rad
310.32° = ?
Angle in radian = 310.32° × 0.0174533 = 5.41610573 ≈ 5.42 rad

Answers
Answer:
Area of the triangle covered by the cars = 910.45 square km
Step-by-step explanation:
Since, all the sides of triangle ABC are given,
And formula for the area of a triangle with all sides given is,
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Here, s = [tex]\frac{a+b+c}{2}[/tex]
And a, b, c are the measures of the sides of the triangle.
If a = 39 km, b = 87 km and c = 58 km
s = [tex]\frac{39+87+58}{2}[/tex]
s = 92
Therefore, (s - a) = 92 - 39
= 53
(s - b) = 92 - 87
= 5
(s - c) = 92 - 58
= 34
Now area of the triangle ABC = [tex]\sqrt{92(53)(5)(34)}[/tex]
= [tex]\sqrt{828920}[/tex]
= 910.45 km²
Area of the triangle covered by the cars = 910.45 square km

Answer:
Since f(n + 1) = f(n) - 3, we can also say that f(n - 1) = f(n) + 3.
By which we can say f(n - 3) = f(n) + 9
Since f(4) is 22, then f(1) must be 22 + 9, or 31.
