Answer:
Martin is the answer
Step-by-step explanation:
Incorrect - Martin is putting in $25 a week which means each week his bank is growing by exactly $25
Correct - Cali's pay is exponential since it is increasing each year by a percentage, so not a steady rate.
Incorrect - The athlete's weight is decreasing, so the opposite of growth.
Incorrect - And mei-lin can change how many hours she works so she will get a different amount for the time she works each day.
Hopefully, this helped, have a great day!

Answer:
60
Step-by-step explanation:
[tex]180 - 2(60) = 60[/tex]
Answer:
60°
Step-by-step explanation:
A triangle with two 60° angles has another 60° because 180-(60+60)=180-120=60°.
Also, this is an equilateral triangle.

Step-by-step explanation:
what does this mean 4x + 6y=9
12x + 18y=27
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x /4 = −6y+9 /4
(Divide both sides by 4)
x= −3 /2 y+ 9 /4
Substitute
−3 /2 y+ 9 /4
for x in 12x+18y=27:
12x+18y=27
12( −3 /2 y+ 9 /4 )+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)

Tanisha and Bess are sisters. Tanisha is half as old as Bess. Bess is 6 years older than Tanisha.
How old is each sister?
A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.
Answer: a
Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3
The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.
We need to find the age of Tanisha and Bess.
What is an equation?A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Let the age of Tanisha be x.
Bess is 6 years older than Tanisha.
Now, Bess=x+6
Tanisha is half as old as Bess.
Now, Tanisha=1/2×Bess
⇒x=1/2×(x+6)
⇒x=6
So, Tanisha's age=6 years and Bess's age=12 years.

Step-by-step explanation: Divide the number of campers by 30 then multiply by 4 because that’s the amount of counselors per 30 campers
Solve the two-step equation. 14=31.7-3x
Answer:
x=5.9
Step-by-step explanation:
First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

A ladder that is 13 feet long leans against a building .The bottom of the ladder is 5 feeet away from the base of the building .how far up the side of the building does the ladder reach?
Length of the ladder = 13 m
Foot of the ladder from the wall = 5 m.
The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.
In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.
In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.
In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.
So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.
Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m
wall ^ 2 + ground ^ 2 = 13^2 = 169
w^2 + g^2 = 169
w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12
Rate of change of ground distance = dg / dt = 2m/s (given).
In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.
2 w dw/dt + 2 g dg/dt = 0
2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0
dw/dt = -20 / 24 = -5 / 6
Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)
The minus sign denotes that the height of the ladder is falling.

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

The value of 'k' for the given system of equation that coincides is 4
k=4
Given :
System of equations

Answer:
a) 21 √m inches
b) 13√2/2 m
Step-by-step explanation:
a) we want to find the perimeter of an equilateral triangle
An equilateral triangle is one which sides has the same equal length
The perimeter of this triangle is the sum of the lengths of the three sides
Mathematically, we have this as:
7 √m + 7 √m + 7 √m
= 21 √m inches
b) we want to calculate the perimeter of the given rectangle
Mathematically, we can calculate the perimeter of a rectangle using the formula below;
P = 2(l + b)
where l represents the length of the rectangle and b represents the breadth of the rectangle
From the given shape;
l = √50 m, b = 1/2 √32
So, we have the perimeter follows;
2( √32/2 + √50)
= √32 + √50/2
√32 = 4√2
√50 = 5√2
Thus, we have;
4 √2 + 5 √2/2
= (8 √2 + 5 √2)/2 = 13√2/2
