Answer:

hopes it helps
Step-by-step explanation:
solve for x, using the secant lines. 53° 189°
The measure of the arc opposite to 189° is 136°.
What are secant lines?Secant lines are lines that intersect a curve at two distinct points. They are used to approximate the slope of the curve by measuring the change in the y-coordinate of the two points divided by the change in the x-coordinate of the two points.
The measure of the angle opposite to 189° is x.
To solve for x, we can use the property of alternate interior angles.
The sides of the two secant lines that intersect outside the circle form alternate interior angles whose measures are equal.
Therefore, the two angles formed by the secant lines inside the circle must have the same measure.
Therefore, 53° + x° = 189°.
Subtracting 53° from both sides, we get x° = 136°.

Answer:
Step-by-step explanation:
The equation of any line perpendicular to a line with an equation of x= (vertical line) will have the form y= (horizontal line). In this case, since this line passes through the y value of 3, that means that the equation is y=3.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Marcus buys a pair of shoes that cost $35.99 plus 5.5% tax.
Tia buys a pair of shoes that cost $39.99 plus 9% tax.
Tia uses a coupon for 15% off her purchase.
So, total cost of Marcus payment = 35.99+ 35.99 x 0.055 = $37.97
and, total cost of Tia payment = 39.99+ 3*.99 x 0.09 - 39.99 x 0.15= $37.05
Hence, the difference in the total costs = $37.97 - $37.05 = 0.92 cents

The average profit loss of a company was document it for 30 months. The 6th month showed a loss of $3000 however the 24th month showed a profit of $6000. assuming the profit loss is linear, write the equation of the line and slope intercept form, that represents a profit loss for each month X. use this result to predict the profit loss after 60 months. use the order pairs (6,-3),(24,6)
Slope intercept form:
y=mx+b
Where:
m= slope
b= y-intercept
Apply the slope formula:
\(m=\frac{y2-y1}{x2-x1}\)where:
(x1,y1) = (6,-3)
(x2,y2) = (24,6)
Replacing:
\(m=\frac{6-(-3)}{24-6}=\frac{6+3}{24-6}=\frac{9}{18}=\frac{1}{2}\)So far:
y= 1/2x + b
Replace (x,y) by a point (6,-3) and solve for b
-3 = 1/2 (6) + b
-3= 3 +b
-3 - 3 = b
-6= b
Final equation
y = 1/2x - 6
profit/loss after 60 months (x)
y = 1/2 (60) -6
Y= 30 - 6
y= 24
profit = $24,000

Hundred Metal Spheres with a radius of 4cm each are melted. The melted solution is filled into a cube with a base area of 16cm x 10cm. Find the height of the cube filled with solution.
Answer:
Height = 167.47 cm
Step-by-step explanation:
volume of one sphere = 4/3πr³ = 4/3(3.14)(4³) = 267.9467 cm³
267.9467 cm³ x 100 spheres = 26794.67 cm³
volume of cube = L x W x H
26794.67 = 16 x 10 x H
H = 167.47 cm
Answer the questions below to find the total surface area of the can.
Answer:
\(\begin{aligned}SA &= 7.125\pi \text{ in}^2\\& \approx 22.4 \text{ in}^2 \end{aligned}\)
Step-by-step explanation:
We can find the Surface Area of the can by adding the areas of each of its parts:
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
First, we can calculate the area of the circular base:
\(A_{\text{circle}} = \pi r^2\)
\(A_{\text{base}} = \pi (0.75 \text{ in})^2\)
\(A_{\text{base}} = 0.5625\pi \text{ in}^2\)
Next, we can calculate the area of the rectangular side:
\(A_\text{rect} = l \cdot w\)
\(A_\text{side} = (4\text{ in}) \cdot C_\text{base}\)
Since the width of the side is the circumference of the base, we need to calculate that first.
\(C_\text{circle} = 2 \pi r\)
\(C_\text{base} = 2 \pi (0.75 \text{ in})\)
\(C_\text{base} = 1.5 \pi \text{ in}\)
Now, we can plug that back into the equation for the area of the side:
\(A_\text{side} = (4\text{ in}) (1.5\pi \text{ in})\)
\(A_\text{side} = 6\pi \text{ in}^2\)
Finally, we can solve for the surface area of the can by adding the area of each of its parts.
\(SA = 2( A_{\text{base}}) + A_\text{side}\)
\(SA = 2(0.5625\pi \text{ in}^2) + 6\pi \text{ in}^2\)
\(\boxed{SA = 7.125\pi \text{ in}^2}\)
\(\boxed{SA \approx 22.4 \text{ in}^2}\)

27,813 students took the ACET this year. If only 2,836 students were admitted into the Ateneo among those students, what is the Ateneo’s acceptance rate? a. 7.5% b. 10.2% c. 13.4% d. 9.0%
If only 2,836 students were admitted into the Ateneo among 27,813 students, who took the ACET this year, the Ateneo’s acceptance rate is b. 10.2%.
How the rate is determined:The rate is the ratio of one value, expression, measurement, or quantity compared to another.
The rate represents the quotient of the numerator and the denominator.
The rate is expressed as a percentage by multiplication with 100.
The number of students who took the ACET this year = 27,813
The number of students who were admitted into the Ateneo = 2,836
The percentage or rate admitted = 10.19667% (2,836 ÷ 27,813 × 100)
= 10.2%
Thus, we can conclude that the acceptance rate or percentage is Option B.

A teacher knows that scores on one of her tests are heavily left skewed, with a mean score of 78 and a standard deviation of 18. She randomly selects 15 grades and records the mean score. What is the shape of the distribution of the sample mean for all possible random samples of size 15 from this population?
-skewed left
-skewed right
-approximately normal
-approximately uniform
The sample mean distribution is approximately normal with a mean of 78 and a standard deviation of 4.65 can use the normal distribution to calculate probabilities of sample means falling within certain ranges.
The shape of the distribution of the sample mean for all possible random samples of size 15 from this population is approximately normal.
The Central Limit states that if the sample size is large enough (typically n ≥ 30) and the population is not extremely skewed or has extreme outliers then the distribution of sample means will be approximately normal regardless of the shape of the population distribution.
The sample size is 15, which is relatively small but since the population is not extremely skewed the sample mean distribution will still be approximately normal.
The standard deviation of the sample mean can be calculated using the formula:
standard deviation of the sample mean = standard deviation of the population / square root of sample size
The standard deviation of the population is 18 and the sample size is 15 so the standard deviation of the sample mean is:
standard deviation of the sample mean = 18 / √(15)
≈ 4.65

From the question we are told that
A baker will supply 18 jumbo cinnamon rolls to a cafe at a price of $3.89 each.
If she is offered $3.51, then she will supply 2 fewer rolls to the cafe.
\(p = D(x) = -0.65x + 9.71.\)
Generally
The supply curve equation is
