Answer:
37
Step-by-step explanation:
To find the side length in the middle is 12. This is because A(12) squared + B(5) squared = C(13) squared.
Now that we know the side length, we can find x. A(35) squared + B(12) squared = C(x) squared.
35*35=1225.
12*12=144.
1225+144=1369
The root of 1369 is 37, so the value of x is 37.

Step-by-step explanation:
steve has a photo and a rectangular piece of card. the photo is 16cm by 10cm. the card is 30cm by 15cm. steve cuts along the dotted line shown in the diagram below teve throws away the piece of card that is 15 cm by x cm. The piece of card he has left is mathematically similar to the photo. Work out the value of x.
Answer:
24cm
Step-by-step explanation:
The photo stays the same, the card changes. They must be proportional to each other.
15 by x cm means the 30 is going to be shortened, since it is being cut.
16 / 10 = 1.6
1.6 x 30 = 24
or
[tex]\frac{16}{10} = \frac{x}{15} \\\\Divide\\\\\frac{16}{10} *\frac{15}{x} = \frac{240}{10x} = 24[/tex]

On a coordinate plane, which BEST describes where the point (0, 11) lies?
A) in Quadrant I
B) on the x-axis
C) on the y-axis
D) in Quadrant II
Answer:
The y- axis
Step-by-step explanation:
If it was (0,0) then the x and y would not matter but in this cause the answer is the y axis because it has a point to it but not the x. It is not Quadrant 2 or 1 because it does not matter what box it is in all that matters is where the points are located

A cone is stacked on top of a cylinder. They both share a circular base. The total height of the composite figure is 25. The height of the cylinder is 13 and the radius is 5.
Which expression represents the volume, in cubic units, of the composite figure?
Pi(52)(13) – One-third pi (52)(12)
Pi(52)(13) – One-third pi (52)(25)
Pi(52)(13) + One-third pi (52)(12)
Pi(52)(13) + One-third pi (52)(25)
Answer:
C
Step-by-step explanation:
[tex]\pi (5^{2})(13)+\frac{1}{3} \pi (5^{2})(12)[/tex]
The expression that represents the volume of the composite figure is Pi(5^2)(13) + One-third pi (5^2)(12).
What is the volume of the composite figure?The volume of the composite figure is the sum of the volume of the cone and the volume of the cylinder.
A cone is stacked on top of a cylinder.
They both share a circular base.
The total height of the composite figure is 25.
The height of the cylinder is 13 and the radius is 5.
The expression represents the volume, in cubic units, of the composite figure;
The volume of a cylinder = πr²h
π = 22/7
r = radius = 5
h = height = 13
The volume of a cylinder = π(5²)(13)
The volume of a cone = 1/3(πr²h)
π = 22/7
r = radius
h = height = 25 - 13 = 12
The volume of a cone = (1/3)(π(5²)(12)
The expression represents the volume, in cubic units, of the composite figure is;
= Pi(5^2)(13) + One-third pi (5^2)(12).
Hence, the expression that represents the volume of the composite figure is Pi(5^2)(13) + One-third pi (5^2)(12).

Answer: "distance from zero on a number line"
Explanation: Absolute value means "distance from zero" on a number line.
Since distance can either be 0 or positive,
absolute value is either 0 or positive.
Absolute value is represented with vertical bars on either side of the number.
An example is shown below, we have the absolute value of -5.
The absolute value of a number is just
the positive version of that number.
So the positive version of -5 is 5.
Which function is equivalent to g(x) = x2 + 15x -54?
Answer: (x+18)(x-3)
Step-by-step explanation:
It matched (sorry for no explanation)
The equivalent form of the given expression of the function is [tex]g(x)=(x+18)(x-3)[/tex].
Given information:
The given expression of the function is [tex]g(x) = x^2 + 15x -54[/tex].
We have solve the expression of function to get a relevant expression.
The function is a quadratic polynomial function. So, here we can factorize it as,
[tex]g(x) = x^2 + 15x -54\\g(x)=x^2+18x-3x-54\\g(x)=x(x+18)-3(x+18)\\g(x)=(x+18)(x-3)[/tex]
Therefore, the equivalent form of the given expression of the function is [tex]g(x)=(x+18)(x-3)[/tex].

Jaxson and his children went into a movie theater and he bought $42.50 worth of drinks and candies. Each drink costs $6 and each candy costs $3.25. He bought a total of 8 drinks and candies altogether. Write a system of equations that could be used to determine the number of drinks and the number of candies that Jaxson bought. Define the variables that you use to write the system.
Answer:
6d+3.25c=42.50
d+c=8
Step-by-step explanation:
let's say d is for drinks and c is for candy.
each drink is $6
each candy is $3.25
the porblem told us our total $42.50
so if we mulitpy the cost of each drink and candy together
6d+3.25c=42.50
and
Since he bought a total of 8 drinks and candies, we know that d+c=8
Answer:
Let d = the number of drinks
Let c = the number of candies
6d+3.25c=42.50
d+c=8

simplify a⁵ × (a³)²
Answer:
[tex]a^{11}[/tex]
Step-by-step explanation:
In solving for a⁵ × (a³)², we need to follow the rules of PEMDAS
Therefore, your equation would look like this:
a⁵ × (a³)² = a⁵ × [tex]a^{6\\[/tex]
When two variables are the same, we add their exponents when multiplying and we would subtract them if we divided.
With that information, your final answer would be
[tex]a^{11}[/tex] as 5+6 = 11
Hope this Helps!
In mathematics, the expression a⁵ × (a³)² simplifies to a¹¹ by following rules of exponents. Simplify within parentheses first to get a⁶, then combine to get a¹¹.
Explanation:The term a⁵ × (a³)² represents the product of a number 'a' raised to the power of 5 and 'a' raised to the power of 3, squared. To simplify an expression like this, use the rule of exponents that states: aⁿ * aᵐ = aⁿ+ᵐ and for (a^n)^m, this equates as a^(n*m).
Start by simplifying the exponent in the parentheses first: (a³)² = a^(3*2) = a⁶. Then you're left with a⁵ × a⁶. Using the rules of exponents again, you add the powers together: a^(5+6) which simplifies to a¹¹.

What is the approximate length of arc QR? Round to the nearest tenth of a centimeter
a. 7.2 cm
b. 25.8 cm
c. 94.2 cm
d. 14.4 cm
PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Given:
The diameter of the circle P is 30 cm.
The radius of the circle P is 15 cm.
The measure of ∠RPS is 125°
We need to determine the arc length of QR.
Measure of ∠QPR:
The angles QPR and RPS are linear pairs.
Thus, we have;
[tex]\angle QPR + \angle RPS=180^{\circ}[/tex]
Substituting the values, we have;
[tex]\angle QPR + 125^{\circ}=180^{\circ}[/tex]
[tex]\angle QPR =55^{\circ}[/tex]
Thus, the measure of ∠QPR is 55°
Arc length of QR:
The arc length of QR can be determined using the formula,
[tex]Arc \ length =(\frac{\theta}{360})2 \pi r[/tex]
Substituting [tex]\theta=55[/tex] and r =15, we get;
[tex]Arc \ length =(\frac{55}{360})2 (3.14)(15)[/tex]
[tex]Arc\ length = \frac{5181}{360}[/tex]
[tex]Arc \ length =14.4 \ cm[/tex]
Thus, the arc length of QR is 14.4 cm.
Hence, Option d is the correct answer.
A circle has a circumference of 5. An arc in the circle has a central angle of 162°. What is the length of the arc?
Answer:
The length of the arc is 2.25 units.
Step-by-step explanation:
The circumference of a circle is [tex]2\pi r[/tex], where r is radius of the circle.
Total angle of a circle in degree is 360°.
Length of central angle formula
[tex]\textrm{Arc length}=\frac{2\pi r}{360^\circ}\times \textrm{central angle degree}[/tex]
[tex]\Rightarrow \textrm{Arc length}=\frac{\textrm{circumference}}{360^\circ}\times \textrm{central angle degree}[/tex]
Given that,
A circle has a circumference of 5 units.An arc in the circle has a central angle of 162°.
Then,
[tex]\textrm{Arc length}=\frac{\textrm{circumference}}{360^\circ}\times \textrm{central angle degree}[/tex]
[tex]\textrm{Arc length}=\frac{5}{360^\circ}\times162^\circ[/tex]
[tex]=\frac{810}{360}[/tex]
[tex]=\frac{9}{4}[/tex]
=2.25 units.
The length of the arc is 2.25 units.
Answer:
14.14 units

Answer:
b.[tex]9\sqrt{3}in[/tex]
Step-by-step explanation:
We are given that
Length of equilateral triangle=a=18 in
Base of oblique pyramid is an equilateral triangle.
We have to find the height of the triangular base of the pyramid
Height of the triangular base of the pyramid,h=[tex]acos\theta[/tex]
We know that each angle of equilateral triangle =60 degree
[tex]\theta=\frac{60}{2}=30^{\circ}[/tex]
Substitute the values
Height of triangular base of the pyramid,h=[tex]18cos30=18\times \frac{\sqrt 3}{2}[/tex]in
Using the value of
[tex]cos30^{\circ}=\frac{\sqrt 3}{2}[/tex]
