Suman made a cardboard box in the form of a cube without lid if the total surface area of this box was 180 square cm what are the dimensions of the box
Answer:
6cm
The dimensions are 6cm x 6cm x 6cm
Step-by-step explanation:
Surface area of a cube = 6a²
where a = edge
but because this cube isn't covered, the sides would by 5 and not 6
5a² = 180cm²
divide both sides by 5
a² = 36cm²
Find the square root of each side
a = 6cm
The dimensions are 6cm x 6cm x 6cm

how do i describe what each variable and parameter means in an exponential equation
y=a(b)x
Answer:
A general exponential equation is written as:
y = a*(b)^x
Where:
y represents the amount of something as a function of the variable x, where x is an independent variable.
a is the initial amount, this is, the value of y when x = 0.
b is the rate of growth, this defines how much changes the value of y as x increases.

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.

If the ratio of boys to girls in the school band is 2 to 3, which of these show possible numbers
of the boys and girls in band.
A. 24 boys, 36 girls
B. 20 boys, 35 girls
C. 36 boys, 24 girls
D. 35 boys, 20 girls
Answer:
A
Step-by-step explanation:
Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3
A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)
36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)
Yes
Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys
B: 20 ÷ 2 = 10 (divisible)
35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)
No
C: 36 ÷ 2 = 18
24 ÷ 3 = 8
Yes, they are divisible
Now lets check if boys have a lower count than girls
36 boys > 24 girls
This is not the solution as it doesn't reflect the correct ratio of less boys than girls
D: 35 ÷ 2 = 17.5 (not divisible)
20 ÷ 3 = 6.66 (not divisible)
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.

C. 2
D. -4
The value of 'k' for the given system of equation that coincides is 4
k=4
Given :
System of equations

The given equation is in the form of ax+by=c
When the two lines coincides then
