We know radius is half of d, so r=0.5*2.75=1.375 inr=0.5∗2.75=1.375in
The height is given as 4 in.
Pluggin all of these in the original formula gives us:

Answer:
b1= 2A/h - b2
Step-by-step explanation:
You have to multiply each side by 2, then divide each side by h. after that you subtract b1 from both sides and then you will get your answer.
Answer:
b1 = 2A / h - b2
Step-by-step explanation:
A = h(b1 + b2) / 2
[cross multiply]
h(b1 + b2) = A × 2
b1h + b2h = 2A
[divide both sides of the equation by h]
b1h / h + b2h / h = 2A / h
b1 + b2 = 2A / h
[make b1 the subject of the formula]
b1 = 2A / h - b2

A rectangle's base is 8 in shorter than three times its height. The rectangle's area is 16 in?. Find this rectangle's dimensions.
The rectangle's height is..
The rectangle's base is..
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
Let the height of rectangle be = x,
height = x base = 3x - 8Area of rectangle = base × height
[tex](3x - 8) \times (x) = 16[/tex][tex]3 {x}^{2} - 8x = 16[/tex][tex]3 {x}^{2} - 8x - 16 = 0[/tex][tex]3 {x}^{2} - 12x + 4x - 16 = 0[/tex][tex]3x(x - 4) + 4(x - 4) = 0[/tex][tex](3x + 4)(x - 4) = 0[/tex]so, there are two cases now,
Case - 1 :
[tex]3x + 4= 0[/tex][tex]3x = - 4[/tex][tex]x = \dfrac{ - 4}{3} [/tex]here, value of x (length) is negative, measure of length can't be negative, so length is not equal to -4/3
Case - 2 :
[tex]x - 4 = 0[/tex][tex]x = 4[/tex]here, value of x = 4, and satisfys the condition so
length = x = 4 in base = 3x - 8 = (3 × 4) - 8 = 12 - 8 = 4 inThe rectangle's height is 4 inches and the rectangle's base is also 4 inches.
Let's assume the height of the rectangle is 'h' inches.
According to the given information, the base of the rectangle is 8 inches shorter than three times its height. This can be expressed as:
Base = 3h - 8
The area of a rectangle is given by the formula:
Area = Length * Width
In this case, the area is given as 16 square inches. We can set up the following equation:
16 = h * (3h - 8)
Expanding the equation:
[tex]16 = 3h^2 - 8h[/tex]
Setting the equation equal to zero:
[tex]3h^2 - 8h - 16 = 0[/tex]
To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's solve it using the quadratic formula:
[tex]h = (-b \± \sqrt{b^2 - 4ac}) / (2a)[/tex]
For this equation, a = 3, b = -8, and c = -16. Plugging in the values:
[tex]h = (-(-8) \± \sqrt{(-8)^2 - 4 * 3 * (-16)}) / (2 * 3)\\\\h = (8 \± \sqrt{64 + 192}) / 6\\\\h = (8 \± \sqrt{256}) / 6\\\\h = (8 \± 16) / 6[/tex]
We have two possible values for h:
h₁ = (8 + 16) / 6 = 4
h₂ = (8 - 16) / 6 = -1
Since the height of a rectangle cannot be negative, we can discard the value h₂ = -1.
Therefore, the rectangle's height is 4 inches.
Now, we can find the base of the rectangle:
Base = 3h - 8
Base = 3 * 4 - 8
Base = 12 - 8
Base = 4
Therefore, the rectangle's base is also 4 inches.

15. One of two complementary angles is 18 less than the other.
Find the measure of each angle.
Answer: 36° and 54°
Step-by-step explanation:
Let the larger angle be 'R' and the smaller angle 'q'
⇒ R + q = 90 [since complementary angles have a sum of 90°]
Then R - q = 18 [since 1 of 2 complementary angles is 18 less than other]
We can combine the equation
(18 + q) + q = 90
18 + 2q = 90
2q = 72
q = 36
We can solve for R
R - 36 = 18
q = 36 + 18
q = 54

Which statement best describes how ultrasound can produce an image?
A. Sound waves emitted by the machine bounce off tissues and
return to the machine.
B. Sound waves that form outside the body reflect off the body and

where they are detected.
D. Sound waves emitted by the machine pass through the body and
are measured on the other side.
Answer:
A
Step-by-step explanation:
just did it :)
The statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.
What is Ultrasound?Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.
We have some statements that describes how ultrasound can produce an image.
The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body to provide the information necessary to produce an image.
Therefore, the statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

Pls Hurry: Ruben bought 2 candy bars and 4 bags of chips for $24. Lucia bought 2 candy bars and 2 bags of chips for $14. What was the cost of the individual candy bar and a bag of chips?
Answer:
A candy bar costs $0.80
A bag of chips costs $6.20
Step-by-step explanation:
Let's call candy bars x, and bags of chips y.
Ruben ought 2x and 4y for $24
Lucis bought 2x and 2y for $14
This means that 2x+4y = 24 and 2x+2y = 14
Now we have a system of equations that we can solve.
2x + 2y = 14
2(x + y) = 14
x + y = 7
y = 7 - x
Plug this into the next equation to get:
2x + 4y = 24
2x + 4(7 - x) = 24
2x + 28 - 7x = 24
28 - 5x = 24
-5x = -4
x = -4/-5
x = 4/5 = 0.8
plug that x value into y = 7 - x to find y
y = 7 - x
y = 7 - (4/5)
y = 245/35 - 28/35
y = 217/35 = 6.2
now we can check our work:
2(x + y) = 14
2(6.2 + 0.8) = 14
2(7) = 14
14 = 14
^ this means our values are correct

The equation y= 1/3x represents a proportional relationship. What is the constant of proportionality? A. x B. 0 c. 1/3 D. 3
Answer:
C ) 1/3
Step-by-step explanation:
In the given equation, y = 1/3x, where it represents a proportional relationship:
1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.
The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.
Therefore, the correct answer is C) 1/3.
A man uses 2/5of his piece of land to keep poultry,1/4 for bulls, 1/7 of the remainder for goats and test for sheep.If he uses 12 acres for goats, determine the total acreage he uses for sheep. (3marks)
Answer:
72
Step-by-step explanation:
We will first have to find the fraction of the whole land goats use. If we add 2/5 and 1/4, we will get 13/20. Simplifying the expression 1-13/20 gets 7/20, which is the total fraction of land the goat and sheep has. The goat will then get 7/20*1/7 of the whole land, which is 1/20. The sheep will then get 7/20*6/7 of the entire land, which is 3/10. Because 1/20 of the whole land is 12 acres, the farmer has 240 acres. SImplifying the expression 240*3/10 gets 72 acres
Challenge A movie theater sends out a coupon for 15% off the price of a ticket. Write an equation
for the situation, where y is the price of the ticket with the coupon, and x is the original price of the
ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be
in the first quadrant
Answer:
The equation is y= 0,65 x
If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately pays (y) is the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.
The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).
Step-by-step explanation:
The price without discount (or without the coupon) is x.
The price with discount (or with coupon) is y.
y and x are both related: y is a percentage of x, specifically, y is 35% smaller than x. This means that y =0.65 x.
Answer:
0.85x

Step-by-step explanation:
The sum of an infinite geometric series is expressed according to the formula;
a 1 r where;
a is the first term of the series
r is the common ratio
If the sum of an infinite geometric series is three times the first term, this is expressed as
S∞ = 3a
Substitute S = 3a into the formula above to get the common ratio r;
a
3a 1-r
cross multiply
3a(1-r) = a
3(1-r) = 1
open the parenthesis
3- 3r 1
subtract 3 from both sides
