the length of a rectangular box is 8cm. If its diagonal is 10cm. Find its width
Answer:
Step-by-step explanation:
The diagonal of this rectangular box serves as the hypotenuse of the 2 right triangles that exist within this rectangle. The length is one leg, the hypotenuse is...well, the hypotenuse, so we need to use Pythagorean's Theorem to find the missing leg.
[tex]10^2=8^2+x^2[/tex] and

Find an equation of the line through the given points right the answer and slope intercept form
Answer:
equation is y = 2-x
Step-by-step explanation:
x1 = -3
y1 = 5
x2 = 4
y2 = -2
now
m(slope) = rise/run =(y2-y1)/(x2-x1) =(-2-5)/(4+3) = -7/7 = -1
so m = -1
now
y =mx + b
-2 = -1×4 + b
or, -2 = -4 +b
so, b = 2
now
y = mx+b
y = -1x + 2
or, y = 2-x

Tameeka tells Marcus, "When you add 16 to my mystery number then subtract 20, you get the same result as when you add my mystery number to itself, then add 20 and subtract 16.” What is Tameeka’s mystery number?
Write and solve an equation to represent this situation.
Answer:
-8.
Step-by-step explanation:
x + 16 - 20 = 2x + 20 - 16
x - 4 = 2x + 4
x - 2x = 4 + 4
-x = 8
x = -8.
The mystery number 'm' that satisfies the stated conditions is - 8.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Let, The mystery number be 'm'.
So, When you add 16 to my mystery number then subtract 20,
m + 16 - 20,
you get the same result as when you add my mystery number to itself, then add 20 and subtract 16,
m + m + 20 - 16.
Therefore,
m + 16 - 20 = m + m + 20 - 16
m - 4 = 2m + 4.
- m = 8.
m = - 8.

Answer:
slope = [tex]\frac{6}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is

The number line that represents the solutions to Ix - 5| = 1 is the number line in the second option.
To solve absolute value equations like |x-5| = 1
We will write that
x - 5 = 1 and x -5 = -1
For the first equation
x - 5 = 1
Add 5 to both sides
x - 5 +5 = 1+5
∴ x = 6
For the second equation
x -5 = -1
Add 5 to both sides as well
x -5 +5 = -1 +5
∴ x = 4
Hence, x = 6 and x = 4
From the image, the second option is dotted (blue) at 4 and 6 on the number line.
Hence, the number line that represents the solutions to Ix - 5| = 1 is the number line in the second option

The can of tomato soup has the same volume, but a radius of 2.5 inches. What is the height of the can of tomato soup?
Use ≈3.14 and round your answer to the nearest tenth.
Questions
Answer:
The height of the tomato soup can is 2.6 in.
Step-by-step explanation:
"The can of chicken noodle soup has a height of 4 inches and a radius of 2 inches."
We can find the volume of this can.
V = pi r² h
V = 3.14 * (2 in.)² * (4 in.)
V = 50.24 in.³
"The can of tomato soup has the same volume, but a radius of 2.5 inches."
Now we know the volume of the can, so we can find the height, h.
V = pi r² h
50.24 in.³ = 3.14 * (2.5 in.)² * h
50.24 in.³ = 19.625 in.² * h
h = (50.24 in.³)/(19.625 in.²)
h = 2.56 in.
Answer: The height of the tomato soup can is 2.6 in.
Answer:
:Volume of can of chicken noodle soup=50.24inch^3
:Height of can of tomato soup=2.56inches
Step-by-step explanation:
CHICKEN NOODLE SOUP :height=4inches
:radius=2inches
[ V=πr2h]
V=(3.14×2×2×4)=50.14
Now, Volume is same of both the can.
Volume of can of tomato soup=50.24;radius=2.5inches;
Height of can of tomato soup,
50.24=(3.14×2.5×2.5×h)
50.24=19.625h
h=50.24/19.625
=2.56inches

Algebra!! In the triangle to the below, the measure of ∠A equals the measure of ∠B. Find the value of x.
Answer:
x=21
Step-by-step explanation:
45=2x+3
Subtract 3 from both sides of the equation.
42=2x
Divide 2 from both sides of the equation.
21=x
Hope this helps!
Answer:
x=21°
Step-by-step explanation:
Angle A = Angle B
Angle A = 45°
2x+3 =45°
To work out what x is, you would have to do inverse operations.
45-3=42°
2x=42°
42÷2=21° (We divide by 2 because, in algebra, whenever a number is next to a letter, it means times, so then we have to do the opposite and divide).
So, x=21°

The output of a relation is the difference of three times the input and five. Select the correct answer from each drop-down menu. The equation that represents this relation is . The relation a function. If the domain of the relation is x > 2, the range of the relation is y > .
Answer:
The equation that represents this relation is [tex]y = 3x - 5[/tex].
The relation is a function.
If the domain of the relation is x > 2, the range of the relation is [tex]y >1[/tex]
Step-by-step explanation:
Given
Output = 3 * Input - 5
Required
Complete the gap
Solving (a):The equation for the relation.
Let
[tex]x \to[/tex] input
[tex]y \to[/tex] output
The relation is:
[tex]y = 3 * x - 5[/tex]
[tex]y = 3x - 5[/tex]
Solving (b): Is the relation, a function?
Yes; Because every value of x has a distinct value in 7
Solving (c): The range:
Domain: [tex]x > 2[/tex]
Substitute 2 for x in [tex]y = 3x - 5[/tex]
[tex]y =3 * 2 - 5[/tex]
[tex]y =6 - 5[/tex]
[tex]y =1[/tex]
The range is:
[tex]y >1[/tex]
Answer:
The equation that represents this relation is [ y= 3x - 5 ]
The relation [ is ] a function.
If the domain of the relation is x > 2, the range of the relation is y > [ 1 ].
Step-by-step explanation:
The output, y, of a relation, is the difference of three times the input, or 3x, and 5. So, y = 3x − 5.
Substituting any x-value from the domain into the equation will result in exactly one value of y, so the relation is a function.
To find the range of the relation, given the domain, substitute the boundary point of the domain into the function equation:
When x = 2, y = 3(2) − 5 = 6 − 5 = 1.
Because substituting values of x that are greater than 2 will result in values of y that are greater than 1, the range of the relation is y > 1.
Hope this helps !!

Triangles ABC and XYZ are similar. Find side x.
Answer:
x=6
Step-by-step explanation:
side AB is proportional to side XY
side AC is proportional to side XZ
Since we know side AB and side XY are proportional to each other, if we divide side AB by side XY, we can find the size difference...
12 / 4 = 3
The smaller triangle is 3 times smaller than the bigger triangle so we can find side XZ by dividing side AC by 3...
18 / 3 = 6
x = 6
The measure of the length of x is 9 units.
What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "≈".
Given triangles ABC ≈ XYZ
for similar triangles, corresponding sides are proportionately equal and corresponding angles are congruent,
so AB/XY = AC/XZ = BC/YZ
substitute the values
12/4 = 18/x = 9/YZ
12/4 = 18/x
x= 9 units
Hence the value of x is 9 units.
