Answer:
Perimeter of ΔABC = 16.46 units
Step-by-step explanation:
By applying cosine rule (CAH) in the given triangle ADB,
cos(∠BAC) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(55°) = [tex]\frac{3}{AB}[/tex]
AB = 5.23 units
Since, ΔABC is an isosceles triangle
AB = BC = 5.23 units
AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]
Therefore, AC = AD + DC = 6 units
Now perimeter of ΔABC = AB + BC + AC
= 5.23 + 5.23 + 6
= 16.46 units

In May 2019 the average price of a liter of milk in France was 1.09 euros. Given that a liter is equivalent to 0.264172 US gallons, and that the exchange rate at that time was $1 equals 0.89 euros, find the equivalent of US dollar price for a gallon of French milk.
9514 1404 393
Answer:
$4.64/gal
Step-by-step explanation:
€1.09/(1 L) × $1/(€0.89) × (1 L)/(0.264172 gal) ≈ $4.64/gal
__
To convert units, multiply by a fraction that has numerator and denominator equal, but with different units. The units you don't want should be placed in the fraction so they cancel the units in the measure you're converting.
Here, we want dollars per gallon. So, we start with the currency value and quantity we're given: euros per liter.
Since euros is in the numerator and we want dollars there, we multiply by a fraction that has dollars in the numerator and euros in the denominator: $1/€0.89.
We have liters in the denominator and we want gallons there. We can cancel the liters unit by putting it in the numerator of our conversion factor: (1 L)/(0.264172 gal).
Multiplying euros per liter by these two conversion factors give us the equivalent in dollars per gallon.

Answer:
f(x) = -½x + 16
Step-by-step explanation:
Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.
✔️Slope (m) = change in y/change in x
Using, (0, 16) and (4, 14),
Slope (m) = (14 - 16)/(4 - 0) = -2/4
m = -½
✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.
Thus,
When x = 0, y = 16
Therefore,
b = 16
✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b
Thus:
f(x) = -½x + 16

Trigonometry dilation
Answer:
Point E
Step-by-step explanation:
Notice that point E is the only point where you can draw a straight line from E to A' to A, E to B' to B, etc. That is, the line doesn't have to turn or bend to reach these three points. This doesn't work with any other point, so you know E is the point of dilation.
You can more firmly determine this by looking at the ratios of the distances. Notice how E is the only point where the ratio from of E to A and E to A' is equal to the ratio from of E to B and E to B', and so on for each vertex of the quadrilateral.

what is the amount of money whose 25percent is Rs 350
Answer:
Rs 1400
Step-by-step explanation:
Let us take the required number be x. According to question ,
=> 25% of x = Rs 350
=> 25/100 × x = Rs 350
=> x = Rs 350 × 100 / 25
=> x = Rs 1400
• Hence the required answer is Rs 1400.A countries population in 1994 was 184 million. In 1997 it was 190 million. Estimate the population in 2015 using the exponential growth formula. Round your answer to the nearest million.

Question 2 of 40
Elena is going to a farmer's market for fresh produce. She has two markets to
choose from and hopes to buy both cherries and asparagus. The table shows
the probability that each type of produce will be available at the markets.
North
market
South
market
Cherries
0.8
0.65
Asparagus
0.55
0.6
Assuming that the availability of cherries and the availability of asparagus are
independent of each other, which market should Elena choose to maximize
her chance of buying both?
To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes,
n(S) is the total number of events in the sample space.
What are independent events?"These are two events wherein the occurrence of one event does not affect the occurrence of another event"
Probability of independent events:If A, B are independent events then their combine probability is given by,
P(A ∩ B) = P(A) × P(B)
For given example,
Let P(A) represents the probability of cherries available at market and P(B) represents the probability of asparagus available at market.
The availability of cherries and the availability of asparagus are
independent of each other
So, the probability of buying cherries as well as asparagus from the North market would be,
⇒ P = P(A) × P(B)
⇒ P = 0.8 × 0.55
⇒ P = 0.44 ....................(1)
And the probability of buying cherries as well as asparagus from the South market would be,
⇒ P = P(A) × P(B)
⇒ P = 0.65 × 0.6
⇒ P = 0.39 .......................(2)
From (1) and (2),
To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.

A piece of string 85 cm is divided into three pieces in the ratio 2 : 3: 5. Calculate: i) shortest piece
Answer: 17 cm
Step-by-step explanation:
First step is to add up the numbers in the ratio:
= 2 + 3 + 5
= 10
The shortest piece according to the ratio is the 2 in the ratio. To find out the length this 2 corresponds with, use two as the numerator and 10 as the denominator:
= 2 / 10 * 85 cm
= 17 cm

[tex]\frac{3}{8}[/tex]
Step-by-step explanation:
After Saturday, there was [tex]\frac{5}{8}[/tex] of the journey left. [tex]\frac{3}{5}[/tex] of that would be:
[tex]\frac{5}{8}[/tex] * [tex]\frac{3}{5}[/tex] = [tex]\frac{15}{40}[/tex] = [tex]\frac{3}{8}[/tex] of the journey.
