Answer 1

Answer:

B. 160 inches

Step-by-step explanation:

The wrapping paper would be the surface area of the box.

The surface area of a box is 2(h * W) + 2(h * L) + 2(W * L)

h = height

W = width

L = length

length x width x height

length = 5 in

width = 2 in

height = 10 in

2(10 * 2) + 2(10 * 5) + 2(2 * 5)

2(20) + 2(50) + 2(10)

40 + 100 + 20

160 inches

x=16 y=21

x= 32 y= 26

Answers

Answer:

the last one

Step-by-step explanation:

32+26=58

32-26=6

Answer:

The first number is 32 and the second is 26

Step-by-step explanation:

Let the two numbers be represented by x and y

1) x + y = 58

2) x - y = 6

x = 6 + y, we'll use put this in the first equation.

x + y = 58

6 + y + y = 58

6 + 2y = 58

2y = 58 - 6

2y = 52

2. 2

y=26, now let's find x, again use the first equation

x + y = 58

x + 26 = 58

x = 58 - 26

x = 32

The expression showing the number of students in the drama club the next year is 15+d.

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

m∡BCA = 57°

Step-by-step explanation:

find 'x' by adding all expressions and setting them equal to 360°

9x+1 + tx+12 + 10x-37 = 360

24x = 384

x = 16

m∡BCA is supplemental with 123°, therefore it measures 57°

The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?

Answers

An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,

V ∝ h(r²)

Also, k is the constant of proportionality, therefore, the equation now can be written as,

V = k×h×r²

Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².
