The measure of [tex]\angleWYX = 150^{\circ}[/tex]
Step-by-step explanation:
[tex]\triangle WXY[/tex] is isosceles and [tex]\angle YWX[/tex] and [tex]\angle YXW[/tex] are base angles.
Isosceles Triangle:
A triangle with two equal sides, and two congruent base angles that means the angles are equal
By the definition, the base angles are equal i.e, [tex]m\angle YWX=m\angle YXW[/tex]
Since, YZ bisects [tex]m\angle WYX[/tex]
Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles
then, [tex]\angle WYX =2\angle XYZ[/tex] or
Substitute the value of [tex]\angle XYZ=(15x)^{\circ}[/tex] ;
[tex]\angle WYX =2(15x)^{\circ} = (30x)^{\circ}[/tex]
The sum of measures of these three angles of triangle WXY is equal to the 180 degree.
In triangle WXY we have;
[tex]\angle YXW+\angle WYX+\angle YWX=180^{\circ}[/tex]
Substitute the value of [tex]m\angle YWX=m\angle YXW=(2x+5)^{\circ}[/tex] and [tex]\angle WYX=(30x)^{\circ}[/tex] in above formula:
[tex]2\angle YXW+30x=180^{\circ}[/tex] or
[tex]2\cdot(2x+5)+30x=180^{\circ}[/tex]
Simplify:
[tex]4x+10+30x=180^{\circ}[/tex]
Combine like terms ;
[tex]34x+10^{\circ}=180^{\circ}[/tex] or
[tex]34x=170^{\circ}[/tex]
Simplify;
[tex]x= \frac{170}{34} =5^{\circ}[/tex]
Substitute the value of x in [tex]\angle WYX [/tex];
[tex]\angleWYX = (30x)^{\circ} = 30 \cdot 5 = 150^{\circ}[/tex]
Therefore, the measure of [tex]\angleWYX = 150^{\circ}[/tex]

A) 3x−4y=10
B)4x−3y=10
C)4x−3y=−10
D)3x−4y=−10
2.What is the slope-intercept form of the linear equation x + 4y = 12? Enter your answer in the box.
3.Graph the equation on the coordinate plane. y=1/2x
Answer: 1. A) 3x−4y=10
2. [tex]y=-\frac{x}{4}+3[/tex]
3. In the attachment.
Explanation:
1. Given equation=[tex]y=\frac{3}{4}x-\frac{5}{2}[/tex]
To reduce it into standard form , multiply both sides by 4,we get
[tex]4y=4(\frac{3}{4}x-\frac{5}{2})\\\Rightarrow4y=3x-10......[distributive\ property]\\\Rightarrow3x-4y=10[/tex] which is option A.
2. Given linear equation : x+4y=12
The standard slope intercept form is given by y=mx+c where m is the slope and c is the constant.
To reduce given linear equation subtract x from both sides, we get
4y=12-x
Divide 4 on both sides.
[tex]\Rightarrow\ y=\frac{12-x}{4}=3-\frac{x}{4}\\\Rightarrow\ y=-\frac{x}{4}+3[/tex] is the slope-intercept form of the linear equation x + 4y = 12.
3. To graph equation [tex]y=\frac{1}{2}x[/tex] on the coordinate plane.

The length of a rectangle is 2 cm longer than its width. if the perimeter of the rectangle is 36 cm , find its area.
The area of the rectangle is 80 square cm.
Explanation:To find the area of a rectangle, we need to know the length and width. Let's denote the width of the rectangle as 'w'. As given, the length of the rectangle is 2 cm longer than its width, so the length can be represented as 'w + 2'.
The perimeter of a rectangle is the sum of all four sides. In this case, it is given as 36 cm. Using the formula for the perimeter of a rectangle, we can set up the equation:
2(w + w + 2) = 36
Simplifying the equation:
4w + 4 = 36
4w = 32
w = 8
Substituting the value of 'w' back into the expression for length:
Length = 8 + 2 = 10
The area of a rectangle is given by the formula: area = length × width. So, the area of this rectangle is:
Area = 10 × 8 = 80 square cm

A rectangle has a perimeter of 60 inches and length of 22 what is the width of the rectangle
perimeter = 2l +2w
length = 22
perimeter = 60
60 = 2(22) +2w
60 = 44 +2w
subtract 44 from both sides
16 = 2w
w = 16/2
w = 8
width is 8 inches

It takes an older pump twice as long to drain a certain pool as it does a newer pump. working together, it takes the two pumps 3 hours to drain the pool. how long will it take the newer pump to drain the pool working alone
It would take the newer pump 4.5 hours to drain the pool working alone.
Given that,
It takes an older pump twice as long to drain a certain pool as it does a newer pump.
Let us assume that,
The time it takes for the newer pump to drain the pool alone is x hours.
Hence, According to the information given, the older pump takes twice as long, so it would take 2x hour to drain the pool alone.
Now, When both pumps work together, their combined rate of draining the pool is additive.
Therefore, the equation is,
[tex]\dfrac{1}{x} + \dfrac{1}{2x} = \dfrac{1}{3}[/tex]
Simplify the equation for x,
[tex]\dfrac{(2 + 1)}{2x} = \dfrac{1}{3}[/tex]
[tex]\dfrac{(3)}{2x} = \dfrac{1}{3}[/tex]
Cross multiplication,
[tex]3 \times 3 = 2x[/tex]
[tex]2x = 9[/tex]
Dividing both sides by 2:
[tex]x = 4.5[/tex]
Therefore, it would take the newer pump 4.5 hours to drain the pool working alone.

A jar of coins contains dimes, pennies, and quarters. There are 220 pennies in the jar. There are 3 quarters for every 4 pennies, and there is 1 dime for every 3 quarters. How many dimes and quarters are in the jar?
A.55 dimes and 165 quarters
B.98 dimes and 293 quarters
C.73 dimes and 98 quarters
D.165 dimes and 55 quarters
Answer:
A. 55 dimes and 165 quarters
Step-by-step explanation:
Given,
The number of pennies in the Jar = 220,
∵ There are 3 quarters for every 4 pennies,
i.e. 4 pennies = 3 quarters,
⇒ 1 penny = [tex]\frac{3}{4}[/tex] quarter
⇒ 220 pennies = [tex]220\times \frac{3}{4}[/tex]
[tex]=\frac{660}{4}[/tex]
= 165 quarter.
Therefore, there are 165 quarters.
Now, there is 1 dime for every 3 quarters,
i.e. 3 quarters = 1 dime
⇒ 1 quarter = [tex]\frac{1}{3}[/tex] dime,
⇒ 165 quarters = [tex]\frac{165}{3}[/tex] = 55 dimes.
Therefore, there are 55 dimes.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We knowt that there are 365 days per year, 24 hours per day, 12 months per year, and 60 minutes per hour.
1 day = 24 hour
1 hour = 60 minutes.
1 minutes = 60 seconds
Therefore, 24 hours = 24 x 60 = 1440 minutes
There are 1440 minutes in one day.
Then 30 days = 30 x 1440 = 43,800
Hence, It is found that there are 43,800 minutes in a month.

ray bought 5 lemons and 3 limes for $7.20. Lia bought 4 lemons and 6 limes for the same price. How much would it cost to buy 1 lemon and 1 lime?
Answer: The cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.
Step-by-step explanation:
Let x be the cost of 1 lemon and y be the cost of 1 lime.
Then for Ray, the equation representing total price will be :-
[tex]5x+3y=7.20[/tex]................................(1)
For Lia, the equation representing total price will be :-
[tex]4x+6y=7.20[/tex]..................................(2)
Dividing 2 on the both sides of equation (2), we get
[tex]2x+3y=3.60[/tex]...............................(3)
Subtracting (3) from (1), we get
[tex]3x=3.6\\\\\Rightarrow x=1.2[/tex]
Substitute value of x in (3), we get
[tex]2(1.2)+3y=3.6\\\\\Rightarrow2.4+3y=3.6\\\\\Rightarrow3y=1.2\\\\\Rightarrow y=0.4[/tex]
Thus, the cost of 1 lemon is $1.2 and the cost of 1 lime is $0.4.

The fuel for a chain saw is a mix of oil and gasoline. The ratio of ounces of oil to gallons of gasoline is 5:18. There are 36 gallons of gasoline. How many ounces of oil are there?
16 ounces
10 ounces
129.6 ounces
2.5 ounces
The amount of oil, in ounces, in the fuel mix can be found using a proportion with the given ratio and the amount of gasoline.
Explanation:To find the number of ounces of oil, we need to use the given ratio and the amount of gasoline. The ratio of oil to gasoline is 5:18, meaning that for every 5 ounces of oil, there are 18 gallons of gasoline. Since we know that there are 36 gallons of gasoline, we can set up a proportion to find the number of ounces of oil:
5 ounces / 18 gallons = x ounces / 36 gallons
Cross multiplying, we get:
18x = 5 * 36
Simplifying further:
18x = 180
Dividing both sides by 18, we get:
x = 10 ounces

What are the coordinates of point S"?
Answer:
S''(-3/2, 9/2)
Step-by-step explanation:
In a dilation, the coordinates of every ordered pair in the pre-image are multiplied by the scale factor to create the ordered pairs of the image.
The first dilation has a scale factor of 1/2. This maps:
R(-6, 10)→R'(-6/2, 10/2) = R'(-3, 5)
S(-2, 6)→S'(-2/2, 6/2) = S'(-1, 3)
T(-10, 0)→T'(-10/2, 0/2) = T'(-5, 0)
The second dilation has a scale factor of 3/2:
R'(-3, 5)→R''(-9/2, 15/2)
S'(-1, 3)→S''(-3/2, 9/2)
T'(-5, 0)→T''(-15/2, 0)
This makes S'' have coordinates (-3/2, 9/2).

if tan(145) = -1/1.43 , what is tan(-125) A. -1.43, B. 1.43, C. 1/1.43, D. -1/1.43
Answer:
B. 1.43
Step-by-step explanation:
Because tan (180-θ)=-tan θ
[tex]tan (145) = tan (180 -35)= -tan 35 = -\frac{1}{1.43}\\tan 35 =\frac{1}{1.43}[/tex]
Because tan (90+θ) = -cot θ
tan (-125) can be written as:
[tex] tan(-125)=-tan (125) = - tan (90+35) = cot 35[/tex]
tan θ x cot θ =1
⇒tan 35 x cot 35 = 1
⇒[tex]\frac{1}{1.43} \times cot 35 =1 \\ cot 35 = 1.43[/tex]
⇒[tex] tan(-125)= cot 35 = 1.43[/tex]
