What is the area of a square?The area of a square can be calculated as the square of the sides of a given figure.
The area of a square = side x side
Given that square has an area of 196.
The region contains two overlapping squares that is the larger of these squares has an area 4 times that of the smaller and the area of their overlap is 1.
We can come up with equations as;
Since the area of their overlap is 1 then the side length is 1 unit.
Let the length of the smaller square is x.
The length of the larger square is 2x.
Therefore,
x + 2x - 1 = 3x - 1
Thus, 3x - 1 = 14
x = 5

through: (-4, 1) and (1, -3) how do u write the point slope form of the equation of the line through the given points ?
Answer:
through: (-4, 1) and (1, -3) how do u write the point slope form of the equation of the line through the given points ?
Step-by-step explanation:
to find slope you do delta y over delta x meaning 3 - 1 over 1 - (-4) you get 2/5 that is slope then you do to find b you take one of the points and you plug in for y = mx + b doesn't matter which one so -3 = 2/5 (1) + b
-3 = 2/5 + b
subtract 2/5 from both sides you get
-17/5 = b
so the equation is
y = 2/5x - 17/5

In triangle ABC, which side is the longest if these are the measures of the angles?
mzA= 60°, mzB = (3x - 2)°, mzC = (2x + 7)°
Applying the triangle sum theorem and the angle-side relationship, the longest side of triangle ABC is: side AC.
What is the Triangle Sum Theorem?The triangle sum theorem states that if we add all three interior angles of a triangle, the sum we get would be equal to 180 degrees.
What is the Angle-Side Relationship of a Triangle?The angle-side relationship of a triangle explains that the longest side of a triangle is always opposite to its largest angle, the medium side is opposite to the medium angle, and the shortest side is to the smallest angle of the triangle.
Given that triangle ABC has the following angle measures:
m∠A = 60°
m∠B = (3x - 2)°
m∠C = (2x + 7)°
Therefore:
m∠A + m∠B + m∠C = 180
Substitute:
60° + (3x - 2)° + (2x + 7)° = 180
60 + 3x - 2 + 2x + 7 = 180
Combine like terms:
65 + 5x = 180
5x = 180 - 65
5x = 115
x = 23
Find the measure of each of the angles by plugging in the value of x:
m∠B = (3x - 2)° = 3(23) - 2 = 67°
m∠C = (2x + 7)° = 2(23) + 7 = 53°
The largest angle is m∠B = 67°.
AC is opposite to angle B, therefore, AC is the longest side of the triangle.

In a concrete mixture, the ratio of cement to sand is 1 to 4. At this ratio, how many shovelfuls of cement would be needed to be mixed with 80 shovelfuls of sand?
Answer: 20 shovelfuls of cement would be needed to be mixed with 80 shovelfuls of sand.
Step-by-step explanation:
First, we'd find out 4 divided by 1. This would equal 4.
Because we knew the amount of sand we had, we'd divide instead.
80 divided by 4
(If we had known the amount of cement we had, we would multiply)
This equals 20. This is how we get our answer, 20 to 80
The equation 5x + (–2y) = 8 relates the amount spent, y, to the number of picture frames purchased, x, after a discount for buying two or more frames is applied to the total cost of the frames. How much is the discount?
The equation for straight line can be used to plot it on the graph. The amount of discount is 4.
What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
The given equation is as follows,
5x + (–2y) = 8
Here, x is the number of picture frames purchased after discount.
And, y is the total amount spent.
In order to find the discount, write the equation in terms of y as,
5x + (–2y) = 8
=> 2y = 5x - 8
=> y = 5 / 2 x - 4
The above equation can be plotted as a graph which is shown below,
It is found from the graph that slope is 5 / 2 which is the rate of per picture.
Since the frames are being purchased after the discount, from the above graph discount can be obtained as 4.
Hence, the discount on the picture frames is given by 4.

2. You roll a blue number cube and a green number cube. Find P a number less than 2 on the blue cube and an odd number on the green cube.
The probability P (a number less than 2 on the blue cube and odd number on the green cube) is 1/12.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
For the probability,
The sample space of a die is, S = {1,2,3,4,5,6}
The probability of getting a number less than 2 is P(x < 2) = 1/6
The probability of getting an odd number is P(Odd) = 3/6
The required probability is calculated as:
P = 1/6 * 3/6
P = 1/12
Hence, the value of P (a number less than 2 on the blue cube and odd number on the green cube) is 1/12.

Mario is setting up a new tent during a camping trip the tech game was 7 feet of rope the instructions are to use 34.5. Inches of rope to tie a tarp on top of the tack then the remaining rope should be cut into 8 1/4 in section 2 times the 10th two steaks in the ground Mario will use all the rope as instructed right and solve an equation to determine the number of 8 1/4 inch sections of Mario can come from the rope
If Mario will use all the rope as instructed right the number of 8 1/4 inch sections of Mario that can come from the rope is: 6.
How to find the inches?First step is to convert the 7 feet rope to inches
7 feet robes = 84 inches
Second step is to find the inches of rope left
Inches of rope left =84 inches - 34.5 inches
Inches of rope left = 49.5 inches
Now let find the number of 8 1/4 inch sections
Number of 8 1/4 inch sections =49.5 / 8.25

substract 7 from both sides
x/3 = 8 - 7
x/3 = 1

x = 3
4 + 5x = 18
Subtract 4 from both sides
5x = 18 - 4
5x = 14
divide both sides by 5
x = 14/5
x = 2.8
81/x - 3 = 6
Add 3 to both sides
81/x = 6 + 3
81/x = 9
cross product
81 = 9x
divide both sides by 9
x = 81/9
x = 9
24 - 2x = 13
Subtract 24 from both sides
-2x = 13 - 24
-2x = -11
divide both sides by -2
x = -11/-2
x = 5.6
2x - 3 = 15
Add 3 to both sides
2x = 15 + 3
2x = 18
divide both sides by 2
x = 18/2
x = 9
