Step-by-step explanation:
It says for 15 minus a number (meaning a variable like x or y) divided by 2 equals eleven
so 15 - y/2 = 11
For question number 3 it says the insurance company wants 100 dollars in deduction fee and then it will pay 80 percent or 0.8 of the medical costs. so we get
0.8(960- 100)
The reason why we subtract 100 is because we paid the insurance company 100 dollars, so that is our own money going to the medical bills.
then we multiply 0.8 by 860

What are triangles?A triangle is a three-sided polygon because it has three edges and three vertices. The most important attribute of a triangle is the sum of its internal angles to 180 degrees
Given triangle ABC,
and D is a point on AB and E is a point on AC,
and forms a triangle ADE,
and DE is parallel to AC,
taking ΔABC and ΔBDE
∠B = ∠B (common angle)
because DE is parallel to AC, so corresponding angles are equal,
so ∠A = ∠D
and ∠C = ∠E
ΔABC ≈ ΔBDE (triangles are similar)
since both triangles are similar the ratio of their corresponding sides is equal,
AB/BD = AC/DE = BC/BE
given BD = 2, BE = 4, DE = 5 and EC = 6
BC = EC + BE = 4 + 6
BC = 10
AC/DE = BC/BE
AC = 5(10/4)
AC = 12.5
and AB/BD = BC/BE
AB = 2(10/4)
AB = 5
AD = AB - BD
AD = 5 - 2
AD = 3
Hence AC = 12.5 and AD = 3.

Whats the answer please help im stuck
Answers
Answer:
A. \( y = \frac{8}{5}x \).
B. 115.2 ft
Step-by-step explanation:
a. First, we need to find slope of the graph, m, and y-intercept, b.
Then substitute each value of m and b into the equation of the graph, in slope-intercept form, given as y = mx + b.
Using the points in the graph, (0, 0) and (5, 8), calculate the slope using the formula, \( m = \frac{y_2 - y_1}{x_2 - x_1} \).
Thus,
\( m = \frac{8 - 0}{5 - 0} = \frac{8}{5} \)
Slope (m) = ⁸/5 or 1.6
The y-intercept, b, is the point where the line intercepts the y-axis, therefore, b = 0.
Substitute m = ⁸/5 and b = 0 into y = mx + b.
\( y = \frac{8}{5}x + 0 \)
The equation that represents the graph in slope-intercept form is \( y = \frac{8}{5}x \).
b. To determine the distance (y), Kirk would have walked after 72 secs (x), substitute x = 72 into \( y = \frac{8}{5}x \).
\( y = \frac{8}{5}72 \).
\( y = \frac{8*72}{5} = 115.2 ft \).

Answers
In the given origami of the two dimensional figure , the value of angle 2 is 70° and the value of angle 1 is 110 °
Parallel lines are straight lines that do not intersect at any point in geometry.
Parallel planes are three-dimensional pathways that never intersect. Parallel curves do not touch or intersect and have a fixed minimum distance.
From the figure we can see that m∠1 = 4x-30 as they are vertically opposite angles.
Again m∠1 = 3x+5 as they are corresponding angles from the pair of parallel lines.
now let us solve the linear equation to calculate the value of x.
3x+5 = 4x-30
or, -x = -35
or, x = 35
Now
m∠1 = 3x+5 = 110
Therefore m∠2 = 180 -110 = 70 ( straight angle formed whose sum is 180)

A can of "fruit drink" contains 15% sugar and a can of "fruit juice" contains 5% sugar. Both of the beverages will be mixed together to get 10 liters of juice that has 8% sugar. How many liters of "fruit juice" are required?
Answers
By solving a system of equations, we will see that 7 liters of fruit juice are needed.
How many liters of fruit juice are required?Let's define the variables:
x = liters of fruit juice.
y = liters of fruit drink.
We know that the mixture has 10 liters, then:
x + y = 10
And the concentration of these 10 liters is 8%, then the concentration equation is:
x*0.05 + y*0.15 = 10*0.08
Then we have a system of equations:
x*0.05 + y*0.15 = 10*0.08
x + y = 10
Isolating y on the second equation, we get:
y = 10 - x
Replacing that in the first equation we get:
x*0.05 + (10 - x)*0.15 = 10*0.08
x*0.05 + 1.5 - x*0.15 = 0.8
-x*0.10 = 0.8 - 1.5
x*0.10 = 0.07
x = 0.7/0.10 = 7
So 7 liters are used.

What is fractional equivalent?
Equivalent fractions are fractions with distinct numerators and denominators but the same value.
1. The number represented by n has two repeating digits, 15.
2. To convert the repeating decimal to a fraction, we need to identify the place value of the repeating digits. In this case, the repeating digits start immediately after the decimal point, so we need to multiply by a power of 10 that is equal to the number of repeating digits, which is 2.
3. Power of 10 times n = 10^2 x 0.1515... = 15.15...
\(0.1515... x 10^2 = 15.15...\\\\\)
4.
\(10^2n = 15.15...\\\\n = 0.1515...\\\\99n = 15\)
To obtain the equation, we multiplied the original bby 100 to eliminate the decimal, which gives 100n = 15.1515... We then subtracted the original equation from the multiplied equation to eliminate the repeating digits, which gives 99n = 15.
5. 99n = 15
n = 15/99
To obtain the fraction, we divided both sides of the equation by 99.
Therefore, the fractional equivalent of the repeating decimal n = 0.1515... is 15/99, which can be simplified to 5/33 in simplest form.

C. 86.35 feet
D. 2,323.1 feet
Answers
The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.
How to evaluate for the circumference of a circleTo calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).
We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:
Radius of the circular feild = 27.5
circumference of the circular feild = 2 × 27.5 feet × 3.14
circumference of the circular feild = 55 feet × 3.14
circumference of the circular feild = 172.7 feet.
Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Convert the equation f(t) = 227e b= -0.09€ to the form f(t) = ab* Give answers accurate to three decimal places
Answers
= 173.903t
Step-by-step Explanation:
The given equation is: f(t) = 227e^(b*t)
To convert it to the form f(t) = ab, we need to write it in the form of f(t) = a * e^(k*t), where a and k are constants.
Let's start by taking the natural logarithm (ln) of both sides:
ln(f(t)) = ln(227e^(b*t))
Using the properties of logarithms, we can simplify this to:
ln(f(t)) = ln(227) + ln(e^(b*t))
ln(f(t)) = ln(227) + b*t
Now, let's define a new constant, k = b, and rewrite the equation in terms of a and k:
ln(f(t)) = ln(a) + k*t
where a = 227 and k = -0.09
Taking the exponential of both sides, we get:
f(t) = e^(ln(a) + k*t)
f(t) = e^(ln(a)) * e^(k*t)
f(t) = a * e^(k*t)
Substituting the values of a and k, we get:
f(t) = 227 * e^(-0.09*t)
Therefore, the equation f(t) = ab is:
f(t) = 227e^(-0.09t) ≈ 173.903t (rounded to three decimal places)

The equation of line that passes through (4,3) and is parallel to x + y = 6 is y = -x + 7.
What is the equation of line that passes through the given point and is parallel to x + y = 6?The slope-intercept form is expressed as;
y = mx + b
Where m is slope and b is the y-intercept.
Given the equation of the original line
x + y = 6
y = -x + 6
Using the slope intercept, slope m is -1
The equation of a parallel line to y = -x + 6 must have a slope similar to the original slope.
Slope of parallel line = -1
Plug the slope m = -1 and point (4,3) into point-slope formula and simplify.
( y - y₁ ) = m( x - x₁ )
( y - 3 ) = -1( x - 4 )
y - 3 = -x + 4
y = -x + 4 + 3
y = -x + 7
