Suppose S is between R and T. Use the Segment Addition Postulate to solve for the variable. Round to three decimal places. RS = 9y − 2 ST = y + 7 RT = 26
Answer:
The variable y = 2.100
Step-by-step explanation:
Here, we are told to solve for the variable y.
We are asked to use the segment addition postulate. In summary, the postulate is of the opinion that given 3 points X,Y and Z, we can only say that these 3 points are collinear(lie on the same line) if they obey the formula below;
XZ = XY + YZ
Now, we have that S is between R and T.
Mathematically that means;
RT = RS + ST
from the question, we are told that RT = 26, RS = 9y-2 and ST = y + 7
Now, insert these values into the alphabetical equation;
26 = (9y-2) + (y + 7)
26 = 9y-2 + y + 7
26 = 9y+y -2 + 7
26 = 10y + 5
26-5 = 10y
10y = 21
y = 21/10
y = 2.1
Which is y = 2.100 to three decimal places

The formula c = 2.54n can be used to convert a measurement of c centimeters to an equivalent measure of n inches. Henry is 170 cm tall. What is his height, in inches? Round your answer to the nearest tenth of an inch. 66.7 in. 66.8 in. 66.9 in. 67.0 in.
Answer:
66.9
Step-by-step explanation:
Answer:
[tex]\boxed {\tt 66.9 \ inches}[/tex]
Step-by-step explanation:
We are given the formula:
[tex]c=2.54n[/tex]
where [tex]c[/tex] is centimeters and [tex]n[/tex] is inches.
We know that Henry is 170 centimeters tall. Therefore, we can substitute 170 in for [tex]c[/tex]
[tex]170=2.54n[/tex]
We want to find out how tall Henry is, in inches. We must isolate the variable for inches, [tex]n[/tex], on one side of the equation.
[tex]n[/tex] is being multiplied by 2.54. The inverse of multiplication is division. Divide both sides of the equation by 2.54
[tex]\frac{170}{2.54} =\frac{2.54n}{2.54}[/tex]
[tex]\frac{170}{2.54}=n[/tex]
[tex]66.9291339=n[/tex]
Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 9 in the tenth place.
[tex]66.9 \approx n[/tex]
[tex]n \approx 66.9 \ inches[/tex]
Henry is about 66.9 inches tall.
185=-5(10r+3) please help me with this question
Steps to solve:
185 = -5(10r + 3)
~Distribute right side
185 = -50r - 15
~Add 15 to both sides
200 = -50r
~Divide -50 to both sides
-4 = r
Best of Luck!
Answer:
r=-4
Step-by-step explanation:
185= - 5 10 r + 3
37= 10 r + 3
10r = - 3 - 37
10 r = - 40
The profit that a company makes selling an item (in thousands of dollars) depends on the price of the item (in dollars). If p is the price of the item, then three equivalent forms for the profit are
Standard form: - 2 p^2 + 24p - 54
Factored form: -2(p - 3)(y-9)
Vertex form: -2(p-6)^2 + 18.
Which form is most useful for finding a. The prices that give a profit of zero dollars?
b. The profit when the price is zero?
c. The price that gives the maximum profit?
Answer:
Step-by-step explanation:
If the profit of a company made by the company is in the form a quadratic expressions but in the different forms as given in the question.
a). The prices that give a profit of zero dollars.
Expression that is most useful,
Factored form: -2(p - 3)(p - 9) = 0
p = 3, 9
b). The profit when the price is zero .
Standard form:
Profit = -2p² + 24p - 54 = 0
-p² + 12p - 27 = 0
-p² + 3p + 9p - 27 = 0
-p(p - 3) + 9(p -3) = 0
(-p + 9)(p - 3) = 0
p = 3, 9
c). The price that gives the maximum profit.
Vertex form: -2(p - 6)² + 18
Vertex of the given expression → (6, 18)
Maximum profit will be at p = 6.
Therefore, profit = -2(6 - 6)² + 18 = 18

What is the midpoint of points (1,1) and (-6,-8)
Answer:
(-2.5, -3.5)
Step-by-step explanation:
In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.
1 + (-6) = -5
-5/2 = -2.5
1 + (-8) = -7
-7/2 = -3.5
The angle measurements in the diagram are represented by the following expressions.
A= 5x - 15°
B = 2x + 21°
Solve for x and then find the measure of
Answer:
45°
Step-by-step explanation:
A and B are Alternate exterior angles and congruent, thus
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Thus
∠ A = 5x - 15 = 5(12) - 15 = 60 - 15 = 45°
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°

I'm working with varibles on both sides. This is math, also algebra 1. The expression is... 8-4a=16-8a I'm so confused on which side to subtract from. I tried doing +8 on both sides. Please help.
Answer:
a=2
Step-by-step explanation:
You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2
On a map, 2 cm represents 30 mi. The actual distance between two towns
is 75 mi. What is the distance between the towns on the map? USE
NUMBERS ONLY*
Answer:
5 cmStep-by-step explanation:
step one:
Given that the scale of the map is
2cm to represent 30 miles
That is every 1 cm is 15 miles in reality
step one:
what we are solving for is the distance in cm on the map so,
1cm rep 15miles
xcm rep 75miles
cross multiply
Xcm= 75/15
X= 5 cm
hence on the map 75miles distance between the two towns is seen as 5 cm

Why can you not combine the 8a2 and 8a?
Answer:
you can't add or subtract numbers that don't have the same variable or the same exponent
Answer:
You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).

The number of calories consumed from an apple is directly proportional to the number of apples eaten. If 4 apples contain 380 total calories, how many apples would you have to eat to reach a total of 1,045 calories?
Answer:
Step-by-step explanation:
The direct proportion equation is y = kx which reads, "y is directly proportional to x". k is the constant of proportionality. In our case, we read this is as, "the number of calories is directly proportional to the number of apples eaten." Our equation would look like c = ka. We first are given that a = 4 and = 380. We will use that to solve for k:
380 = k4 so
k = 95. Now that know the value of k, we will use that along with the number of calories (1045) to find the number of apples, a:
1045 = 95a so
a = 11
This means that it will be 11 apples that contain 1045 calories.
