Step-by-step explanation:
The measure of angle y is 62°.
I solve this by
We know: Measures of interior angles in a triangle add up to 180°.
Therefore we have the equation:
60° + 58° + y = 180°
118° + y = 180° subtract 118° from both sides
118° - 118° + y = 180° - 118°
y = 62°
The measure of angle x is 122°.
I solve this by
Angles 58° and x are supplementary angles.
Supplementary angles add up to 180°.
Therefore we have the equation:
x + 58° = 180° subtract 58° from both sides
x + 58° - 58° = 180° - 58°
x = 122°
In segment AC, the midpoint is B. If segments AC = 5x-9 and AB = 2x, what is the measure of segment AC.
Answer:
The measure of segment AC is 36 units
Step-by-step explanation:
- The mid-point divides the segment into two equal parts in length
- B is the mid point of segment AC
- That means B divides segment AC into two equal parts in length
∴ AB = BC
∵ AC = 5x - 9
∵ AB = 2x
- The two parts AB and BC are equal in length
∴ BC = 2x
∵ AC = AB + BC
- Substitute the values of AB and BC in the expression of AC
∴ AC = 2x + 2x
∴ AC = 4x
∵ AC = 5x - 9
- Equate the two values of AC
∴ 5x - 9 = 4x
- Add 9 to both sides
∴ 5x = 4x + 9
- Subtract 4x from both sides
∴ x = 9
- Substitute the value of x in any expression of AC
∵ AC = 4x
∵ x = 9
∴ AC = 4(9) = 36
* The measure of segment AC is 36 units
Karina has determined that the weight of a newborn elephant increases at a rate of 6% per week for the first 14 weeks. She
needs to determine how much weight a baby elephant will gain on the 14th week if it weighs 92 lbs. at birth. Write the explicit
formula of the geometric sequence that could be used to model this scenario.
This is an exponential growth problem.
The formula is y = a(1+r)^x
Y would be the final answer
a is the starting value
r is the percent of growth
x is the amount of time ( number of weeks)
The equation is:
y(x) = 92(1.06)^x
For 14 weeks replace x with 14:
y(14) = 92(1.06)^14 = 208 pounds.
Answer: W(n) = 92lb*1.06^n
and W(14) = 92lb*1.06^14 = 208lb
Step-by-step explanation:
We know that at the beginning the baby elephant weighs 92Lbs, and for each week it augments by a 6% (or 0.06 in decimals)
Then, at the end of the first week, the weight is:
92lb*1.06 = 97.52lb
at the end of the second week:
(92lb*1.06)*1.06 = 103.37lb
and so on, so you can see that the pattern is:
W(n) = 92lb*1.06^n
where n is the number of weeks after the birth
W(0) = 92lb
W(1) = 97.52lb
...
And we want to know the weight at the end of the 14th week, so we must find:
W(14) = 92lb*1.06^14 = 208lb
Factorise fully 5x-15
To factorise fully the expression 5x-15, we must search for the greatest common factor (GCF) that can be taken out of both terms. The expression 5x - 15 can be factorised fully by finding the greatest common factor, which is 5. So the expression factorised fully is 5(x - 3).
Explanation:To factorise fully the expression 5x-15, we must search for the greatest common factor (GCF) that can be taken out of both terms.
The GCF of 5x and 15 is 5. Thus, we can pull 5 outside of the equation and divide each term by 5.
The equation becomes: 5(x - 3).
So, the expression 5x - 15 factorised fully is 5(x - 3).

ILL MARK BRAINLIEST ASAP IF CORRECT Write the equation of the quadratic function with roots -9 and and -3 and a vertex at (-6, -1).
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h. k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 6, - 1), thus
y = a(x + 6)² - 1
To find a substitute one of the roots into the equation
Using (- 3, 0), then
0 = a(- 3 +6)² - 1
0 = 9a - 1 ( add 1 to both sides )
1 = 9a ( divide both sides by 9 )
a = [tex]\frac{1}{9}[/tex], thus
y = [tex]\frac{1}{9}[/tex](x + 6)² - 1 ← in vertex form

-5x+8y=-27
-8x+7y=-20
Answer:
x = -1 , y = -4
Step-by-step explanation by elimination:
Solve the following system:
{8 y - 5 x = -27 | (equation 1)
7 y - 8 x = -20 | (equation 2)
Swap equation 1 with equation 2:
{-(8 x) + 7 y = -20 | (equation 1)
-(5 x) + 8 y = -27 | (equation 2)
Subtract 5/8 × (equation 1) from equation 2:
{-(8 x) + 7 y = -20 | (equation 1)
0 x+(29 y)/8 = (-29)/2 | (equation 2)
Multiply equation 2 by 8/29:

A florist can make a grand arrangement in 18 minutes or a simple arrangement in 10 minutes. The florist makes at least twice as many of the simple arrangements as the grand arrangements. The florist can work only 40 hours per week .The profit on the simple arrangements is $10 and. the profit on the grand arrangements is $25. hind the number and type of arrangements that the florist should produce to maximize profit.
Answer:
See explanation
Step-by-step explanation:
Let x be the number of simple arrangements and y be the number of grand arrangements.
1. The florist makes at least twice as many of the simple arrangements as the grand arrangements, so
[tex]x\ge 2y[/tex]
2. A florist can make a grand arrangement in 18 minutes [tex]=\dfrac{3}{10}[/tex] hour, then he can make y arrangements in [tex]\dfrac{3}{10}y[/tex] hours.
A florist can make a simple arrangement in 10 minutes [tex]=\dfrac{1}{6}[/tex] hour, so he can make x arrangements in [tex]\dfrac{1}{6}x[/tex] hours.
The florist can work only 40 hours per week, then
[tex]\dfrac{3}{10}y+\dfrac{1}{6}x\le 40[/tex]
3. The profit on the simple arrangement is $10, then the profit on x simple arrangements is $10x.
The profit on the grand arrangement is $25, then the profit on y grand arrangements is $25y.
Total profit: $(10x+25y)
Plot first two inequalities and find the point where the profit is maximum. This point is point of intersection of lines [tex]x=2y[/tex] and [tex]\dfrac{3}{10}y+\dfrac{1}{6}x=40[/tex]
But this point has not integer coordinates. The nearest point with two integer coordinates is (126,63), then the maximum profit is
[tex]\$(10\cdot 126+25\cdot 63)=\$2,835[/tex]
To maximize profit, the florist should produce 1 grand arrangement and 2 simple arrangements. The maximum profit is $45.
Explanation:To maximize profit, the florist should produce a combination of grand and simple arrangements. Let's assume the florist makes x grand arrangements and at least twice as many simple arrangements, which would be 2x or more. Given that the florist can work only a total of 40 hours per week, we can set up the following equation:
18x + 10(2x) ≤ 40
Now, we solve for x to find the number of grand arrangements.
Simplifying the equation, we have 18x + 20x ≤ 40
Combining like terms, we get 38x ≤ 40
Dividing both sides by 38, we find that x ≤ 1.05
Since we can't have a fraction of an arrangement, the florist should produce 1 grand arrangement. From the given information, we know that the florist must produce at least twice as many simple arrangements as grand arrangements. Therefore, the florist should produce at least 2 * 1 = 2 simple arrangements.
The florist's maximum profit can be calculated by multiplying the profit per arrangement by the number of corresponding arrangements.
The profit for the grand arrangement is $25, so the total grand arrangement profit is 1 * $25 = $25. The profit for the simple arrangement is $10, so the total simple arrangement profit is 2 * $10 = $20. Therefore, the maximum profit is $25 + $20 = $45.

clothes takes from 22 to 28 minutes. Diying
takes an additional 20 to 30 minutes. What
are the woun and maximum total times
to complete a load of laundry?
Final answer:
The time to complete a load of laundry ranges from a minimum of 42 minutes to a maximum of 58 minutes, combining the shortest and longest durations for both washing and drying cycles respectively.
Explanation:
The question asks about calculating the minimum and maximum total times for completing a load of laundry, including washing and drying cycles. The minimum time for washing is 22 minutes, and the minimum time for drying is 20 minutes. Therefore, the minimum total time to complete a load of laundry is 22 + 20 = 42 minutes.
On the other end, the maximum time for washing is 28 minutes, and the maximum time for drying is 30 minutes. The maximum total time to complete a load of laundry is 28 + 30 = 58 minutes.
In conclusion, the entire process of doing laundry, including both washing and drying, takes between 42 and 58 minutes in total.
The length of a rectangle is 6 inches longer than it is wide. If the area is 40 square inches, what are the dimensions of the rectangle?
Answer:
The length is 10 inches, and the width is 4 inches.
By creating a quadratic equation using the known facts and algebra, we can determine that the dimensions of the rectangle with an area of 40 square inches are length= 10 inches and width= 4 inches.
Explanation:This problem is a classic example of using algebra to solve for unknown dimensions. Given that the area (A) of a rectangle equals its length (L) times its width (W), written as A = L x W, you can substitute the given values into this formula. You're told the length is 6 inches longer than the width, which you can denote in algebra as L = W + 6. Secondly, you're given that the area is 40 square inches. Substituting these values gives us the following equation: 40 = W(W + 6).
Solving this equation will give us the width, and substituting the width into the formula L = W + 6, gives us the length.
Solving the Equation:
First, distribute the width on the right side of the equation to get 40 = W^2 + 6W. Re-arranging terms gives W^2 + 6W - 40 = 0. Factoring this quadratic equation yields (W - 4)(W + 10) = 0. Setting each factor equal to zero and solving for W gives W = 4 and W = -10. Because a width cannot be negative, the width of the rectangle is 4 inches. Substituting W = 4 into the length equation results in L = 4 + 6 = 10 inches. Hence, the dimensions of the rectangle are Length = 10 inches and Width = 4 inches.
