1/9 times blank equals 4/27
Answers
The correct value in the blank of the statement "1/9 times blank equals 4/27" is; 4/3
How to divide fractions?We are given the expression that 1/9 times blank equals 4/27.
Let the missing term be identified as y. Thus, we have;
1/9 * y = 4/27
In Mathematics, the reciprocal of any quantity is, one divided by that quantity. For any number 'b', the reciprocal will be 1/b. If the given number is multiplied by its reciprocal, we get the value 1.
To get the missing value y, we will use multiplication property of equality to multiply both sides by 9 to get;
1/9 * y * 9 = 4/27 * 9

The exact area of the shaded region is: (2 - √6)/8 cm².
What is the Area of a Triangle?The area of a triangle = 1/2(base)(height).
The area of the shaded region = area of triangle ABD - area of triangle ACD.
Area of triangle ABD:
Base of triangle ABD = AD = √2/2
Height of triangle ABD = BD = √2/2
Area of triangle ABD = 1/2(√2/2)(√2/2)
Area of triangle ABD = 2/8 = 1/4 cm²
Area of triangle ACD:
Base of triangle ACD = AD = √2/2
Height of triangle ACD = CD = √3/2
Area of triangle ACD = 1/2(√2/2)(√3/2)
Area of triangle ACD = √6/8 cm²
Area of the shaded region = 1/4 - √6/8

When camera has an angle of depression of 50° to a point on the floor and the other camera has an angle of depression of 60° to the same point calculate the height of the gym, the height of gym is 7.05 m
What is angle of depression?When the observer is above the object they are looking at, an angle of depression is created. An angle below the horizontal line drawn with the level of the observer's eye and the line connecting the object with the observer's eye is created when an observer looks at an object that is placed at a distance lower than the observer.
Lets name the points on the triangles as A, B ,C
m∠ABC = 180° - 60° + 50°
= 70°
Now, the sine theorem defines
[tex]\frac{AB}{sin50\textdegree}[/tex] = [tex]\frac{AC}{sin70\textdegree}[/tex] = [tex]\frac{10}{sin70\textdegree}[/tex]
AB = 8.15 meters
Now using the area of triangle formula
area∠ABC = 1/2 × AB × AC × sin∠BAC = 1/2 × h × AC
⇒ 1/2 × 8.15 × 10 × √3/2 = 1/2 × h × 10

Joy buys a shirt using a coupon for 75% off one item. She pays only $15.00 for a shirt. How much
did the shirt cost originally?
Answers
Answer:
$60.00
Step-by-step explanation:
15 is 25% of a number. 25 times 4 equals 100. so 15 times four is 60, making 60 the 100%
Work Shown:
x = original price
75% of x = 0.75x = amount saved
x - 0.75x = 0.25x = final price after discount = 15
0.25x = 15
x = 15/0.25
x = 60
ignoring all other issues, how many pounds of grain supplement should farmer ben feed his cows if the price of milk is $0.20 per pound and the price of grain supplement is $0.70 per pound?
Answers
The most appropriate choice for profit and loss will be given by
Uncle Ben will feed his cows 2 pounds of grain supplement.
What is profit and loss?
If the selling price is more than the cost price, then the difference between the selling price and the cost price will give the profit.
If the selling price is less than the cost price, then the difference between the selling price and the cost price will give the loss.
Here,
For 1 pound
Cost price of grain supplement = [tex]0.70 \times 1[/tex]
= $[tex]$0.70[/tex]
Selling price of milk = [tex]0.20 \times 5[/tex]
= $[tex]1[/tex]
Profit = $([tex]1 - 0.70[/tex])
= $0.30
For 2 pounds
Cost price of grain supplement = [tex]0.70 \times 2[/tex]
= $[tex]$1.40[/tex]
Selling price of milk = [tex]0.20 \times 9[/tex]
= $[tex]1.80[/tex]
Profit = $([tex]1.80 - 1.40[/tex])
= $0.40
For 3 pounds
Cost price of grain supplement = [tex]0.70 \times 3[/tex]
= $[tex]$2.10[/tex]
Selling price of milk = [tex]0.20 \times 12.3[/tex]
= $2.46
Profit = $([tex]2.46 - 2.10[/tex])
= $0.36
For 4 pounds
Cost price of grain supplement = [tex]0.70 \times 4[/tex]
= $[tex]$2.80[/tex]
Selling price of milk = [tex]0.20 \times 15.5[/tex]
= $3.1
Profit = $([tex]3.1 - 2.80[/tex])
= $0.30
For 5 pounds
Cost price of grain supplement = [tex]0.70 \times 5[/tex]
= $[tex]$3.50[/tex]
Selling price of milk = [tex]0.20 \times 18[/tex]
= $3.60
Profit = $([tex]3.60 - 3.50[/tex])
= $0.10
For 6 pounds
Cost price of grain supplement = [tex]0.70 \times 6[/tex]
= $[tex]$4.20[/tex]
Selling price of milk = [tex]0.20 \times 20[/tex]
= $4
Loss = $([tex]4.20 - 4[/tex])
= $0.20
For 7 pounds
Cost price of grain supplement = [tex]0.70 \times 7[/tex]
= $[tex]4.90[/tex]
Selling price of milk = [tex]0.20 \times 21.5[/tex]
= $[tex]4.30[/tex]
Loss = $([tex]4.90 - 4.30[/tex])
= $0.60
For 8 pound
Cost price of grain supplement = [tex]0.70 \times 8[/tex]
= $[tex]$5.60[/tex]
Selling price of milk = [tex]0.20 \times 22.5[/tex]
= $[tex]4.50[/tex]
Loss = $([tex]5.60 - 4.50[/tex])
= $1.10
For 9 pounds
Cost price of grain supplement = [tex]0.70 * 9[/tex]
= $[tex]6.30[/tex]
Selling price of milk = [tex]0.20 * 23[/tex]
= $[tex]4.60[/tex]
Loss = $([tex]6.30 - 4.60[/tex])
= $1.70

In a large population, 56% of the people have been vaccinated. If 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
Answers
The likelihood that someone has received a vaccination equals one minus the likelihood that no one has. The likelihood that a randomly chosen individual in a large population IS NOT immunized = 1 - 0.54 = 0.46.
The likelihood that the three randomly chosen individuals are not all immunized is 0.463, hence the likelihood that at least one of them has been immunized is 1 - 0.463.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

solve g(x) = "-x^2" "-7" when x=-3
Answers
Solution of the given function g(x) = "-x^2" "-7" when x=-3 = 2.
A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
A function called g is defined by the notation y=g(x). This should be understood as "y is a function of x." The input value, or independent variable, is represented by the letter x. The output value, also known as the dependent variable, is denoted by the letter y, or g(x).
Given function
g(x) = -x² -7When x = -3
Whenever you're given a function, you simply plug in the x value you're given and then calculate the result.
g(-3) =(-3²) - 7
g(-3) =(9) - 7
g(-3) =9 - 7
g(-3) =2
Hence, When x=-3 = 2, the given function g(x) has a solution of "-x2" "-7."

Answers
The equation of the parallel line to y = 2x - 1, that passes through (-3, 1) is: y = 2x + 7.
How to Write the Equation of Parallel Lines?Two lines that are parallel to each other would always have the same slope (m). In the slope-intercept form of the equation that represents a line, y = mx + b, the slope of the line is represented as "m", while the y-intercept is represented as b.
Given:
A point (-3, 1)
Equation, y = 2x - 1. The slope (m) = 2. Since parallel lines have the same slope (m), therefore, the line that passes through (-3, 1) also have a slope (m) = 2.
Substitute (x, y) = (-3, 1) and m = 2 into y = mx + b:
1 = 2(-3) + b
1 = -6 + b
1 + 6 = b
b = 7
