Answer:
10x -17
Step-by-step explanation:
The perimeter is the sum of the side lengths:
P = (5x -7) +(3x -4) +(2x -6)
Grouping like terms can make simplification easier:
P = 5x +3x +2x -7 -4 -6
P = 10x -17

The measure of the angles are 60 degrees each
How to determine the measure of the anglesFrom the question, we have the following parameters that can be used in our computation:
AOB = 138 degrees
Also, we have:
The line OX bisects the angle AOB
Using the above as a guide, we have the following:
AOX = AOB/2 = 138/2 = 69
Also, we have
XOB = AOB/2 = 138/2 = 69
Hence, the angles are 69 degrees each

if there are 200 high school students in the district, how many would you expect to be in chemistry?
If there are 200 high school students in the district, the number of high school students expected to be in Chemistry is 60 because the percentage who offer Chemistry in the district is 30%.
How the number is determined:The number of high school students who offer Chemistry in the district can be determined by multiplying the total number of high school students and the percentage of students who offer Chemistry.
The result of a multiplication operation (multiplicand and multiplier), which is one of the basic mathematical operations, is known as the product.
The total number of high school students in the district = 200
The percentage of students who offer Chemistry in the district = 30%
The number of students likely to be offering Chemistry in the district = 60 (200 x 30%).
Thus, we can conclude that 60 high school students are in Chemistry based on the Chemistry percentage.

Circle E has a radius of 5.3 meters. FG is a chord and HE is a perpendicular bisector of FG. If FG = 6.5 meters, calculate the distance of EH.
The distance of EH is 4.1866 meters.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
From the question, we have,
Radius of the circle = 5.3 meters
EF = EI = 5.3 meters
FG = 6.5 meters
Also, we have, HE is a perpendicular bisector of FG.
FH = HG = 6.5 / 2 = 3.25
We have to calculate EH.
We have, FH is the projection of EF in the vertical axis.
FH = EF sin (θ), where θ is the angle FEH.
3.25 = 5.3 sin (θ)
sin (θ) = 0.6132
θ = sin⁻¹ (0.6132)
θ = 37.82°
We have, EH is the projection of EF into the horizontal axis.
EH = EF cos (θ)
= 5.3 cos (37.82°)
= 5.3 × 0.7899
= 4.1866 meters
Hence the length of EH is 4.1866 meters.

In one particular suburb, there are 28 families that own a pug. If these owners make up 80% of all dog owners in this suburb, then how many dog owners are there in this neighborhood?
Answer:
60%
Explanation:
To get percentages, take the part of a population that is being specified and divided that by the whole population and multiply that value by
100%
So there are 30 people that own boxers, this is the specific population that is being compared to the whole dog-owning population, which is comprised of 50 total families. So 30 50 can be reduced to 3 5 and that gives us 0.6
When that value is multiplied by
100%, it gives us our percentage of 0.6 ⋅ 100% = 60
log3 (x-4) =2
log(x+3) 8 =1
Option three log3 + log(x+4) is the equivalent to the logarithm expression log3(x+4).
It is given that logarithm expression is log3(x+4).
It is required to simplify the above equation.
It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
aᵇ = c
logₐc = b
We have logarithm expression:
log3(x+4)
We know the log property that we can split a logarithm into two logarithms if it contains the product of two numbers ie.
log xy = logx + logy
By using this property we get:
log3(x+4)
= log3 + log(x+4)
Because 3 and (x+4) are two different numbers, not (x+4).
Thus, option three log3 + log(x+4) is the equivalent to the logarithm expression log3(x+4).

Let (-3,-2) be a point on the terminal side of theta. Find the csc(theta)
The csc(theta) = 1/sin(theta) = 1/(-2/√13) = -√13/2. So, the cosecant of theta is -√13/2.
To find the cosecant (csc) of theta when a point (-3, -2) lies on its terminal side, we need to determine the hypotenuse (r) of the right triangle formed by this point.
Using the Pythagorean theorem, r^2 = (-3)^2 + (-2)^2. So, r^2 = 9 + 4 = 13, and r = √13.
The csc(theta) is the reciprocal of sin(theta). Sin(theta) is calculated as the ratio of the opposite side (y-coordinate) to the hypotenuse, or sin(theta) = -2/√13.

The cost of the labor per hour
The cost of the labor per hour is $105. the equation can be used to determine x. The cost of labor per hour is $105. the total amount paid by Casho was $627 - $102 (the cost of the parts) = $525. The technician charged her $105 per hour for his labor.
Given, The technician at the store worked on the computer for 5 hours and charged her 102$ for parts a total 627.
Since Casho needed to get her computer fixed, she took it to the repair store. Therefore, the cost of labor per hour can be calculated.
To find the cost of labor per hour, we can use the following formula; Total Cost = Cost of Parts + Labor Cost * Hours Worked Given, Total Cost = 627Cost of Parts = $102 Labor Cost = x (unknown)Hours Worked = 5Thus, the equation can be written as;

A florist must make 5 identical
bridesmaid bouquets for a wedding. The budget is
$160, and each bouquet must have 12 flowers. Roses
cost $2.50 each, lilies cost $4 each, and irises cost
$2 each. The florist wants twice as many roses as the
other two types of flowers combined.
Answer:
A. 40x + 10y + 10z = $160
B. 8 Roses, 2 lilies and 2 irises
C.
1. 20x + 5y + 5z = $80
2. 4x + y + z = $16
3. 8x + 2y + 2z = $32
Step-by-step explanation:
Cost for each flower = $160/5 = $32
So we have $32 for each bouquet consisting of 12 flowers each.
Roses = x = $2.50 each
lilies = y = $4 each
irises = z = $2 each
8x + 2y + 2z = $32
8($2.50) + 2($4) + 2($2) = $32
$20 + $8 + $4 = $32
$32 = $32
a. Maximum budget is $160
40x + 10y + 10z = $160
40($2.50) + 10($4) + 10($2) = $160
$100 + $40 + $20 = $160
$160 = $160
b. From above
8x + 2y + 2z = $32
8 Roses, 2 lilies and 2 irises
c. No. There are other solutions If total cost is not limited
1. 20x + 5y + 5z
20($2.50) + 5($4) + 5($2)
$50 + $20 + $10
= $80
2. 4x + y + z
4($2.50) + $4 + $2
$10 + $4 + $2

3. 8x + 2y + 2z

If two fractions are between 0 and 1, can their product be more than 1? please explain. Thank You.
Answer:
B) always less than either of the original fractions
Step-by-step explanation:
We can easily Answer this by taking some values.
The question states that the two fractions, each have values between 0 and 1.
Let us say one of the fraction is 1/2 and the other fraction is 1/3 .
The product of the two fractions is 1/2 x 1/3 = 1/6 .
is lesser than both 1/2 and 1/3 .
So, the correct answer is that the product is always less than either of the original fractions.
The two fractions are between 0 and 1 their product will always less than either of the original fractions.
What is fraction?A fraction is number expressed "as quotient, in which the numerator is divided by denominator".
According to the question,
If two fractions are between 0 and 1. In order to check their product be more than 1.
Let us assume one fraction is 1/2 and the other fraction is 1/3. The product of the two fractions:
1/2 x 1/3 = 1/6.
Since the value of fraction 1/2 is 0.5, the value of fraction 1/3 is 0.3333 and the value of fraction 1/6 is 0.166667.
It clearly shows 0.5 > 0.16667 and 0.3333 > 0.16667.
Hence, the two fractions are between 0 and 1 their product will always less than either of the original fractions.

We can factor this by grouping - that is factoring the first 2 terms and the last 2:

Answer:
C) 2.421 x 10^-5
Step-by-step explanation:
A negative exponent on a power of ten will make the decimal point go back that amount of times to the left, making it a lesser number. A positive exponent will cause it to move to the right, making the number greater. We aren’t going to need to make any of the numbers being multiplied greater, so we can eliminate the first two. Then we need to solve the others. We can do this by moving the decimal the amount of times that we see the exponent equals. Since C is -5, we move it to the left 5 times, and get the weight of the seed; 0.0002421.
