Answer:
[tex]x=54.6[/tex]
Step-by-step explanation:
Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that [tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]. We are given that [tex]AB=x[/tex], [tex]AC=21[/tex], [tex]SU=13[/tex], and [tex]ST=5[/tex]. After substituting the given values into the proportion and solving for [tex]x[/tex], we get:
[tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]
[tex]\frac{x}{21} =\frac{13}{5}[/tex] (Substitute given values into the proportion)
[tex]5*x=13*21[/tex] (Cross-Products Property)
[tex]5x=273[/tex] (Simplify)
[tex]\frac{5x}{5}=\frac{273}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=54.6[/tex] (Simplify)

Answer:
15/20 16/20 <
Step-by-step explanation:
First, make a common denominator for both, which is 20. So, 3/4 = 15/20. Then 4/5= 16/20. 15/20 < 16/20, so 3/4 < 4/5.
The lengths of two sides of a triangle are 3 feet and 5 feet. Which could be the length of the third side?
(a) 3 feet (b) 8 feet (c) 15 feet (d) 2 feet
Answer:
b) 8 feet
Step-by-step explanation:
5+3=8
So, the answer will be 8
The third length must be 3 feet.
What is a Triangle?a plane figure with three straight sides and three angles.
How to determine?If you are referring to a triangle with known side lengths of 3 and 5, then all we can say about the length of the third side is that it must be more than 3 and less than 5:
If you imagine the two sides (lengths 3 and 5) are the hands of a clock, if the time is 12:00 with both the hands on top of each other, then the distance between the two points of the hands is 5–3 or 2 units, that is the shortest distance between the two endpoints of our clock hands. So the third side of the triangle must be more than 2 units long.

7x + 2
AB =
Answer:
[tex]AB= \frac{97}{3}[/tex]
Step-by-step explanation:
Properties of Rhombus
All sides of the rhombus are equal. The opposite sides of a rhombus are parallel. Opposite angles of a rhombus are equal. In a rhombus, diagonals bisect each other at right angles. Diagonals bisect the angles of a rhombus.We are given two sides of the rhombus BC and CD. According to the first property:
4x + 15 = 7x + 2
Subtracting 4x:
15 = 3x + 2
Subtracting 2:
13 = 3x
Dividing by 3:
[tex]x=\frac{13}{3}[/tex]
It's required to find the side AB. Applying the first property again:
AB= BC = CD = 4x + 15
[tex]AB =4*\frac{13}{3}+15[/tex]
[tex]AB= \frac{52}{3}+15[/tex]
[tex]AB= \frac{97}{3}[/tex]

The solution of 1st and 2nd system of equations have solutions same as the main system of equations and 3rd is not same.
What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
The given equations are;
-2x-5y = -47........(i)
4x-2y = -2
We can simply it, and write;
2x-y = -1
y = 2x+1.....(ii)
Put equation (ii) in (i)
-2x-5(2x+1) = -47
-2x-10x-5 = -47
-12x = -42
x = 7/2
Put value of x in eq (ii)
y = 2(7/2)+1
y = 8
Therefore, the solution of main equation is (7/2, 8)
Solving the other three equations,
1) -14x+y = -41
or, y = -41+14x......(i)
2) 4x-2y = -2
or, 2x-y = -1
y = 2x+1....(ii)
Solving the equations,
2x+1 = -41+14x
12x = 42
x = 7/2
Put x = 7/2, in (ii)
y = 8
Therefore, the solution is (7/2, 8)
We get the solution of main equation is equal to this system of equation.
2) -2x-5y = -47......(i)
6x+3y = 45
or, 2x+y = 15.......(ii)
Solving the equation by elimination,
-4y = -32
y = 8
Put y = 8 in equation (ii)
2x+8 = 15
x = 7/2
Therefore, the solution is (7/2, 8)
Again, we get the solution of main equation is equal to this system of equation.
3) -2x-5y = -47.........(i)
8x-5y = -8.......(ii)
Solving the equations by elimination,
-10x = -39
x = 39/10
Since, value of x is not same as the value of x in main equation, that means, both the system of the equation do not have same solution.
Hence, we get that, the solution of 1st and 2nd system of equations have solutions same as the main system of equations and 3rd is not same.

Look at the following numbers:
-7, 0, 7, 14
Which pair of numbers has a sum of 0?
Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Your answer is B.) -7, 7

At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
What is the average change in temperature per hour?
5.33 F is the average change in temperature per hour.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
Since there is a Sum change in temperature in 3 hours
From the formula of average:
Average change = total change/ time taken
in our case
Total change = 69 - 53
Total change = 16 F
Total time taken = 11 - 8
Total time taken = 3
Thus Average = 16/3
Average = 5.3333
Therefore, the average change in temperature per hour is 5.33 F.

find the volume of a cone with diameter of 12m and a height of 7m
Answer:
A) [tex]84\pi[/tex] or approximately [tex]263.76[/tex] cubic meters
Step-by-step explanation:
The formula for finding the volume of a cone is [tex]V=\frac{1}{3}\pi r^{2} h[/tex] where [tex]V[/tex], [tex]r[/tex], and [tex]h[/tex] are the cone's volume, radius, and height, respectively. We are given that we need to solve for the cone's volume, and we are also given the cone's height, but we don't know its radius. Not to worry though because we are given its diameter, and since radius is simply half of the diameter, we know that the cone's radius is [tex]\frac{12}{2}=6[/tex] m. Now, we know that [tex]r=6[/tex] and [tex]h=7[/tex], so plugging these values into the equation, we get:
[tex]V=\frac{1}{3}\pi r^{2} h[/tex]
[tex]= \frac{1}{3} \pi *6^{2} *7[/tex] (Substitute given values into equation)
[tex]=\frac{1}{3}\pi *36*7\\=84\pi[/tex] (Simplify)
Since [tex]\pi[/tex] is approximately [tex]3.14[/tex], we know that [tex]84\pi =84*3.14=263.76[/tex]. Therefore, the volume of the cone is [tex]84\pi[/tex] or approximately [tex]263.76[/tex] cubic meters. Hope this helps!
Complete the equation to show how many thirds are equivalent to
8/12 = ?/3
Answer:
[tex]\frac{2}{3}[/tex]
Explanation:
What we need to do is to convert [tex]\frac{8}{12}[/tex] into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.
We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of [tex]\frac{8}{12}[/tex] - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.
So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is [tex]\frac{2}{3}[/tex].

w^2+13w+36=(w+4)(w+?)
Answer:
w1= -8, w2 = -4
Step-by-step explanation:
Answer: [tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]
Step-by-step explanation:
[tex]w^{2} + 13w + 36 = (w + 4)(w + ?)[/tex]
w (w + ?) +4 (w + ?)
w² + ?w + 4w + ?
4w + ?w = 13w
Subtract both sides by 4w
?w = 9w
? = 9
4 (?) = 36
Divide both sides by 4
? = 9
[tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]
