Step-by-step explanation:
A quadrilateral has two angles that measure 140° and 70°. The other two angles are in a ratio of 4:11. What are the measures of those two angles?
Answer:
40° and 110°
Step-by-step explanation:
the sum of the 4 angles in a quadrilateral = 360°
the ratio of 2 angles = 4 : 11 = 4x : 11x ( x is a multiplier )
sum the 4 angles, equate to 360 and solve for x
140 + 70 + 4x + 11x = 360
210 + 15x = 360 ( subtract 210 from both sides )
15x = 150 ( divide both sides by 15 )
x = 10
Then
4x = 4 × 10 = 40°
11x = 11 × 10 = 110°
the measure of the 2 angles is 40° and 110°

What is a ratio and proportion?A percentage is an expression that converts two ratios into an equal value. For instance, you may write the ratio as 1: 3 if there is 1 man and 3 women, meaning that 40% of the population is female and 14% is male. For any two numbers, the ratio formula is stated as a: b a/b. The percentage formula, on the other hand, is represented as a:b::c:da:b::c:da:b=cd. In mathematics, a ratio shows how many times one number is represented by another. For instance, if there are eight oranges and six lemons in a dish of fruit, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
The percentage of false positives=3%
The percentage of true positives=49%
Ratio=3/49
Therefore, the ratio of false positives to true positives is 3/49.
So, option B is correct.

the volume of a cube decreases at a rate of 10 m/sec. find the rate at which the side of the cube changes when the side of the cube is 2 m.
If the volume of a cube decreases at a rate of 10 m/sec, then the rate at which the side of the cube changes when the side of the cube is 2 m is -0.83 meter per second
The rate of volume of the the cube decreasing = 10 meter per second
Consider the side of the cube is x
The volume of the cube = x^3
The rate of change of volume with respect to time
dV / dt = 3x^2 dx/dt
dV / dt = -10 meter per second
The dx / dt = (dV / dt) / 3x^2
We haver to find the rate at which side of the cube changes when the side of the cube is 2 meter
Then x = 2
dx / dt = -10 / (3 × 2^2)
= -10 / 12
= -0.83 meter per second
Therefore, the rate at which side of the cube changes when the side of the cubes is 2 meter is -0.83 meter per second

all sides. If the area of the border of the image is 704 square
pixels, what is the area of the image?
The area of the image is, 7396 square pixels.
what is area?
The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.
Let x represent the length and the width of the image.
The area of the image and the border is represented by the expression
(x + 4)^2.
Total area - area of image = Area of border
(x + 4)^2 - x^2 = 704
⇒ x^2 + 8x + 16 - x^2 - 704 = 0
8x - 688 = 0
8x = 688
x = 86
The image will be 86 pixels by 86 pixels.
The area becomes 86*86 = 7396 square pixels.

Determine the coupon payments for the following three bonds: 5. 5% coupon corporate bond (paid annually), 6. 45% coupon treasury note, and a corporate zero-coupon bond maturing in 10 years. (assume $1,000 par value. ).
For the 5.5% coupon corporate bond, the coupon payment would be $55 per year. For the 6.45% coupon treasury note, the coupon payment would be $64.50 per year.
What is Percentage?Calculations using percentages show how much a given number contributes to the total. It is computed by dividing the number by the sum and multiplying by 100. It is denoted by the sign "%." For example, if a basket contains ten apples, three of which are red, the proportion of red apples in the basket is 30% (3/10 x 100). In a wide range of disciplines, including business, statistics, and education, percentage is often utilized. Calculating interest rates, taxes, and other financial activities in the finance industry annually frequently uses percentages. The frequency of events or the likelihood of a certain outcome are both measured using this method in statistics. Calculating grades and evaluating a student's overall performance are both done using this in education.
How to solve?
For the 5.5% coupon corporate bond, the coupon payment would be 5.5% of $1,000 = $55 per year.
For the 6.45% coupon treasury note, the coupon payment would be 6.45% of $1,000 = $64.50 per year.

Submit Answer
attempt 2 out of 2
Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons
What is volume of water?
The form of the container the water is contained in affects how much water is contained inside. You must know the length, breadth, and depth of a square or rectangular vessel in order to calculate its volume using the volume equation V=L*W*D, where L stands for length, W for width, and D for depth. The volume equation in this case reads: V= (r²)Dπ, where r stands for the radius, D for depth, and, or pi, is a constant value that is typically rounded to 3.14. To perform the same volume calculation for a circular vessel, you must know the vessel's depth and diameter or radius.
Given, the water park has water which is 8.6*10⁵ gallons.
We know that 10⁵ = 100000
Thus, 8.6*10⁵ = 860000
The new ride would use an additional 9.1*10⁴ gallons.
Again, 10⁴ = 10000
Thus, 9.1*10⁴ = 91000
Total water that would be required now is equal to the sum of the original water volume and the volume required by the new ride
= (860000+91000) gallons
= 951000 gallons
= 9.51*10⁵ gallons
Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The following expression represents a 2-scale factor vertical stretch, a transformation of 4 units left, and a transformation of 1 unit down:
g(x) = 2f(x + 4) - 1
How to write the given transformation?A vertical stretch of scale factor K is expressed as follows for the general function f(x):
g(x) = Kf(x).
Horizontal translation:
A horizontal translation of N units for a general function f(x) is written as:
g(x) = f(x + N).
The shift is to the left if N is positive and the shift is to the right if N is negative.
Vertical translation:
A vertical translation of N units for a generic function f(x) is expressed as follows:
g(x) = f(x) + N.
When N is positive, there is an upward movement and N shifts downward if it is negative.
So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:
g(x) = 2f(x)
Then we translate it into 4 units left:
g(x) = 2f(x + 4)
Then we translate 1 unit down:
g(x) = 2f(x + 4) - 1
This is the equation for the transformation.

Write a linear equation in the form y=mx+b that represents the table. x 0 1 2 3 4 y 15 13 11 9 7
Answer: A linear equation in the form y = mx + b can be determined by examining the values in the table. To find the value of m, we can use the formula for the slope of a line, which is (y2 - y1) / (x2 - x1). Using the first and last values in the table, we can compute the slope as (7 - 15) / (4 - 0) = -1/4.
Therefore, the equation that represents the table is:
y = (-1/4) * x + b
We can use any of the given points to find the value of b. For example, using the point (1, 13), we can solve the equation to find b:
13 = (-1/4) * 1 + b
b = 14 - 1/4 = 13 3/4
Therefore, the final equation that represents the table is:

What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.
According to our question-
A shampoo's unit price is its cost per ounce. It is a straightforward division problem that may be solved with a simple calculator or pen and paper.
The first size weighs 14.2 ounces and costs $3.98.
This shampoo's unit price is ($3.98/14.2 oz) = $0.28/oz ( rounded off to nearest cent)
The second size weighs 33.9 ounces and costs $9.98.
The second shampoo's unit price is ($9.98/33.9 oz) = $0.29/oz (also rounded off to nearest cent)
Hence, There is just a 0.01% difference between the two. Even though both sizes may be rounded to $0.3/oz, the first size is the preferable choice in terms of unit price.
