Question 1
Use right triangle XYZ to complete the following parts.
Part A
12
XY =
30°
? Question
What is the length of XY in AXYZ?
Type the correct answer in the box. Use numerals instead of words.
units
Answer:
XY = 6
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{XZ}[/tex] = [tex]\frac{XY}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2 XY = 12 ( divide both sides by 2 )
XY = 6
The length of the side XY in ΔXYZ is 6 units.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
In reference to the angle of 30° opposite side is XY and the hypotenuse is 12 units.
We know, sin = opposite/hypotenuse.
Therefore, sin30° = XY/12.
1/2 = XY/12.
XY = 12/2.
XY = 6 units.

Find the measure of each missing angle.
Answer:
Step-by-step explanation:
Angle sum property of triangle: Sum of all the angles of a triangle is 180
Alternate interior angles: When two parallel lines are intersected by a transversal, the pair of angles on the inner side of each of these lines but on the opposite side of the transversal are called alternate interior angles
In ΔABC,
∠1 + 90 + 38 = 180 {angle sum property of triangle}
∠1 + 128 = 180
∠1 = 180 - 128

Answer:
3
Step-by-step explanation:
bc im vary smert
Answer:
15
Step-by-step explanation:
Start by factoring each number into primes.
30 = 2 · 3 · 5
60 = 2 · 2 · 3 · 5
75 = 3 · 5 · 5
Look for prime numbers used in all three factorizations and include these common primes in the greatest common factor (GCF).
Since 3 is used at least one time in all three factorizations, the GCF will contain one 3.
Since 5 is used at least one time in all three factorizations, the GCF will contain one 5.
Therefore, the GCF Fireside Flowers can use to divide the flowers into equal groups is 3 · 5 = 15.

Initially, a box contains three white and five red balls. Balls
are drawn at random from the box. Whenever a red ball is drawn, it is placed
back into the box together with one extra red ball. Whenever a white ball is
drawn, it is placed back into the box together with two extra white balls. What
is the probability that the first three balls are drawn out of the box alternated
in colour?
Using it's concept, it is found that the probability that the first three balls are drawn out of the box alternated in colour is of 0.1541 = 15.41%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Considering the situation described, the ways that alternate colored balls can be taken, and their probabilities, are given as follows:
R(5/8) - W(3/9) - R(5/11).W(3/8) - R(5/10) - W(5/11).Hence the probability is given by:

A pack of sugar costs £1.25 for 500g. How much for 1kg?
Answer:
2.50 £Step-by-step explanation:
A pack of sugar costs £1.25 for 500g. How much for 1kg?
500g = 1/2Kg or 0.5 Kg
so 1.25£ is 0.5Kg (1/2)
1.25 * 2 = 2.50£ is your answer
Answer:
2.5
Step-by-step explanation:
Change 500g into kg
500g=500/1000kg
=0.5kg
If 0.5kg cost 1.25
what about 1kg
= (1*1.25)/0.5
= 1.25/0.5

Write the equation of the line that is parallel to the line y = -x - 2 through the
point (4,-2)
Answer:
y = -x +2
Step-by-step explanation:
Equation of a line in slope-intercept form :
y = mx + b where m = slope and 'b' is the y-axis intercept
y = -x-2 is in this form..... slope m = -1 b = -2
the parallel line will have the same slope = -1 and will look like
y = -x + b
to calculate the value of 'b' for this line, substitute in the point given:
-2 = - (4) + b shows b = 2
so your line becomes y = -x + 2
Answer:
y =-x + 2
Step-by-step explanation:
Equation of line:Parallel lines have same slope.
y = -x - 2
Compare with the equation of the line in slope y-intercept form: y =mx + b
Slope = m = -1
So, equation of line: y = -x + b
Point(4 ,-2) is going through this line. so, substitute x = 4 & y = -2 in the above equation.
-2 = -4 + b
-2 + 4 = b

Cooper was out at a restaurant for dinner when the bill came. His dinner came to $28. After adding in a tip, before tax, he paid $33.32. Find the percent tip.
Cooper left his dinner server a 19% tip.
To find the percent tip, we need to first subtract the cost of the meal from the total amount paid, which will give us the tip amount:
Tip amount = Total amount paid - Cost of the meal
Tip amount = $33.32 - $28
Tip amount = $5.32
Now we can calculate the percentage of the tip by dividing the tip amount by the cost of the meal and multiplying by 100:
Percent tip = (Tip amount / Cost of the meal) x 100
Percent tip = ($5.32 / $28) x 100
Percent tip = 0.19 x 100
Percent tip = 19%
Therefore, Cooper gave a 19% tip on his dinner.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? Write and solve an equation to match the situation.
Answer:
see below
Step-by-step explanation:
Acid in = acid out acid out = 10 liters of 20% = .2 * 10 = 2
x = 5% amount
10-x = 40% amount
.05x + .40 ( 10-x) = .20 (10)
.05x + 4 - .4x = 2
-.35x = -2
x = 5.7 liters of 5 % 10 - 5.7 = 4.3 liters of 40%

Answer: [tex]\textsf{y = 5/7x + 51/7}[/tex]

Given: [tex]\textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}[/tex]
Find: [tex]\textsf{Write an equation that follows that criteria}[/tex]
Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7. We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.
Plug in the values

[tex]\textsf{y - 8 = (5/7 * x) + (5/7 * (-1))}[/tex][tex]\textsf{y - 8 = 5/7x - 5/7}[/tex]Add 8 to both sides
[tex]\textsf{y - 8 + 8 = 5/7x - 5/7 + 8}[/tex][tex]\textsf{y = 5/7x - 5/7 + 8}[/tex][tex]\textsf{y = 5/7x + 51/7}[/tex]Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.
