Sam had $25 more than Mary, and together they had enough money to buy a video game for $57 and to pay $16 for two movie tickets. How much money did Mary have?
Answer:
Mary had $24
Step-by-step explanation:
So to solve this question, we first have to create an equation.
Mary's money=x
Since Sam had $25 more than Mary, $Sam+$Mary is (25+x)+x.
With this money, they can buy something worth $57 and something worth $16, so that means (25+x)+x=57+16
Now we solve the equation-->
(25+x)+x=57+16
Combine x and x to get 2x.
25+2x=57+16
Add 57 and 16 to get 73.
25+2x=73
Subtract 25 from both sides.
2x=73−25
Subtract 25 from 73 to get 48.
2x=48
Divide both sides by 2.
x= 2/48
Divide 48 by 2 to get 24.
x=24

Given g(x)=-2x-1g(x)=−2x−1, find g(-4)g(−4)
Answer:
7
Step-by-step explanation:
The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function f is defined by g(x)=−2x−1
We need to find the function defined as g(-4).
Then substitute;
g(x)=−2x−1
g(-4 ) =−2 (-4) − 1
g(-4 ) = 8 -1
g(-4 ) = 7
Therefore, The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.

The scale factor as fraction in simplest form is 3/2.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given square on the right is a scaled copy of the square on the left.
So 11 is being multiplied by something to get to 33/2
So 11x = 33/2
Solve for x:
11x = 33/2
x = 33/ 2(11)
x = 3/2
The scale factor as fraction in simplest form is 3/2.

Find the area of the shaded portion.
Answer:
Step-by-step explanation:
There's a fact hidden in the diagram that if you do not know it, the problem will be very difficult to solve. The fact is this. If a 60 degree angle is enclosed by the hypotenuse and the other of side of the 60 degree angle. the hypotenuse is 2 times the length of the side.
In this case the hypotenuse is 12. The given side is 6. The third side of the right triangle is 12^1 - 6^2 = 144 - 36 = 108
The length of the third side is sqrt(108) = 6*sqrt(3)= 10.39
The area of one of the triangles is 1/2 * 6 * 10.39 = 31.18
The area of two of the triangles is 2 * 31.18. = 62.36
Now you you have to do is find the area of the unshaded sector
Area = given angle / 360 * pi * r^2
Area = 120/360 * 3.14 * 6^2
Area = 37,68
The area of the shaded part = the area of the 2 triangles - the unshaded sector
The area of the shaded part = 62.36 - 37.68 = 24.68

Answer:
[tex]x=\pm \sqrt{21}/7[/tex]
Step-by-step explanation:
We can add 9 to both sides of the equation to get [tex]21x^2=9[/tex].
We can divide both sides of the equation by 21 to get [tex]x^2=9/21[/tex].
We take the square root of both sides of the equation to get [tex]x=\pm \sqrt{9/21}[/tex].
However, that isn't in the form we need.
We know that [tex]\sqrt{9/21}=\sqrt{9}/\sqrt{21}=3/\sqrt{21}=3\sqrt{21}/(\sqrt{21}*\sqrt{21})=3\sqrt{21}/21=\sqrt{21}/7[/tex]

In a circle of radius 1, what is the length of an arc cut off by a central angle of 2 radians?
Answer:
What is the length of an arc cut off?
If θ (in radians) is a central angle in a circle with radius r, then the length of the arc cut off by θ is given by s = r θ (θ is in radians).
Step-by-step explanation:
Length of an Arc = θ × r, where θ is in radian.
Length of an Arc = θ × (π/180) × r, where θ is in degree.

Answer: Yes they would have enough notepads
Step-by-step explanation:
24 * 5 = 120
15 * 6 = 90
120 + 90 = 210
The organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.
Given that, a store sells notepads in packages of 24 and packages of 6.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, the number of note pads with five packages of 24
24 × 5 = 120
The number of note pads with fifteen packages of 6
15 × 6 = 90
Total number of note pads
= 120 + 90 = 210
Therefore, the organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.
