Step-by-step explanation:
The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.
What is Expression?An expression is combination of variables, numbers and operators.
1. The given equation is x /45 = 3
Now value of x is 45×3
x=135
3. The expression is −5.8 + (−2.5)
−5.8 −2.5
The value of expression is -8.3
4.To find the sale price after a 20% discount, we need to subtract 20% of the original price from the original price:
20% of $399 = (20/100) x $399 = $79.80
Sale price = $399 - $79.80 = $319.20
Therefore, the sale price is $319.20.
5. The side length of cube is 5 cm
Volume = 5³
=125 cubic centimeter
6. y = 8/ x equation represents a proportional relationship
7. 5 ft² is area of the wall will the game board cover
9. The given expression is 5 /8 x 4 /5
20/40
1/2
Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

The diagram shows a 3 cm x 5 cm x 4 cm cuboid
Answer:
a) The length of segment AC is approximately 5.83 centimeters.
b) The angle ACD is approximately 34.5º.
Step-by-step explanation:
a) Since [tex]AB \perp BC[/tex], the length of segment [tex]AC[/tex] is determined by Pythagorean Theorem, that is:
[tex]AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}[/tex]
[tex]AC \approx 5.831\,cm[/tex]
The length of segment AC is approximately 5.831 centimeters.
b) Since [tex]AB \perp BC \perp AD[/tex], the length of segment [tex]AD[/tex] is determined by this Pythagorean identity:
[tex]AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}[/tex]
[tex]AD \approx 7.071\,cm[/tex]
The angle ACD is determined by the following trigonometric expression:
[tex]\cos C = \frac{AC}{CD}[/tex]
[tex]\cos C = \frac{5.831\,cm}{7.071\,cm}[/tex]
[tex]\cos C = 0.825[/tex]
[tex]C = \cos^{-1} 0.825[/tex]
[tex]C \approx 34.448^{\circ}[/tex]
The angle ACD is approximately 34.448º.

What is the volume of a cone with a diameter of 8 in and a height of 5 in?
Answer:
V=80π/3 or V=83.78
Step-by-step explanation:
The volume is
V=πr^2h/3
r=4 (because the radius is half the diameter)
h=5
V=π16*5/3
V=80π/3
Answer:
83.73
Step-by-step explanation:
volume = (1/3) · π · r2 · h
volume = (1/3) x 3.14 x 4^2 x 5
volume = (1/3) x 3.14 x 16 x 5
3.14 x 16 x 5 = 251.2
1/3 x 251.2
83.73

15 lb ≈ ? kg
Answer:
6.82 kg
Step-by-step explanation:
set up a proportion based on 2.2 lbs in 1 kg
2.2/1 = 15/x
cross-multiply:
2.2x = 15
x = 6.82
The value of 15 lb in kg is 6.81 kg.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We know that;
⇒ 1 lb = 0.454 kg
Hence, We get;
⇒ 1 lb = 0.454 kg
⇒ 15 lb = 15 × 0.454 kg
= 6.81 kg
Thus, We get;
⇒ 15 lb = 6.81 kg

Answer:
5 groups
2 extra children
Step-by-step explanation:
The computation of a number of groups and number of extra children is shown below:
Given that
There is 27 children
And, this group would be divided into group 5
So,
As we know that 25 is easily divided by 5
So there are 5 groups

Write an equation describing the relationship of the given variables. y varies inversely as the cube root of x and when x=125, y=8.
Answer:
y = 40 / x^1/3
Step-by-step explanation:
Given that :
y α x^1/3
y = k * 1 / x^1/3
y = k / x^1/3
When x = 125 ; y = 8
8 = k / 125^1/3
Cube root of 125 = 5
8 = k / 5
8 * 5 = k ; k = 40
Hence, expression becomes :
y = 40 / x^1/3
y α k/∛x is the relationship of the variables x and y whose values are 125 and 8.
What is Equation?Two or more expressions connected with an equal sign is called Equation.
The relationship of the given variables. y varies inversely as the cube root of x.
By given data we can write as
y α k/∛x
The cube root of 125 is 5.
y α k/∛125
y α k/5
8=k/5
k=40
Hence y α 40/∛x is the relationship of the variables x and y whose values are 125 and 8.

What is the length of line segment HJ?
Answer:
b = 5√3 (units)
Step-by-step explanation:
To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.
In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.
a^2+b^2 = c^2 (pythagorean therorm)
5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)
25+b^2 = 100 (square the numbers)
b^2 = 75 (subtract 25 from both sides)
b = √75
b = √25 * √3 (factor out√75)
b = 5 * √3 (find square root of√25)
b = 5√3

y= -3x + 1 and y= x - 3
Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2
