The reason that is used to prove ΔFGH ≅ ΔJHK is SAS property
If the three angles and the three sides of a triangle are equal to the corresponding angles and the corresponding sides of another triangle, then both the triangles are said to be congruent.
The two triangles need to be of the same size and shape to be congruent. Both the triangles under consideration should superimpose on each other.
According to the question,
Given : (1) ∠FGH and ∠JHK are right angles
(2) H is midpoint of GK
(3) GH ≅ JK
In ΔFGH and ΔJHK
∠FGH = ∠JHK ( right angles )GH ≅ JK (given) GH = KH ( H is midpoint of GK )Therefore , ΔFGH ≅ ΔJHK using SAS property

Ahab spent the day at the mall. First, he bought three tires for $50 each. Later, he returned one tire. After that, he found a five dollar bill. Also,he bought two jackets for $40 each. Write the total change to Ahab's funds as an integer.
The total change to Ahab's funds is -$175, which means he spent more money than he received and is now $175 poorer
To solve this problem, we need to calculate the total amount of money Ahab spent and the total amount of money he received. We can then subtract the total amount spent from the total amount received to get the total change to Ahab's funds.
The total amount spent on tires is 3 x $50 = $150.
When he returned one tire, he received a refund of $50.
He found a five dollar bill, which adds $5 to his funds.
The total amount spent on jackets is 2 x $40 = $80.
Therefore, the total amount spent is $150 + $80 = $230, and the total amount received is $50 + $5 = $55.
To find the total change to Ahab's funds, we subtract the total amount spent from the total amount received:
$55 - $230 = -$175
Therefore, the total change to Ahab's funds is -$175, which means he spent more money than he received and is now $175 poorer.

Matthew cleaned the garage in 2.5 hours he was paid x dollars per hour he then spent $3 and had $12 remaining how much was he paid per hour?
The amount that Matthew was paid per hour is given as follows:
$6.
How to obtain the amount that Matthew was paid per hour?The amount that Matthew was paid per hour is obtained applying the proportions with the amounts given in this problem. A proportion is a fraction of a total amount, using to obtain amounts in the context of a problem.
He then spent $3 and had $12 remaining, hence the total amount earned is calculated as follows:
x - 3 = 12
x = 12 + 3
x = $15.
(total amount - spent amount = remaining amount).
He earned $15 in 2.5 hours, hence the amount that Matthew was paid per hour is found applying the division of 15 by 2.5, as follows:
15/2.5 = $6.
(amount per hour = total amount divided by the number of hours).

What is proportion?Proportion is a mathematical comparison between two numbers. According to proportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other.
Given is an equation, 1/2 + 1/2x = x²-7x+10 / 4x
We need to determine the proportion equivalent to this,
So, taking the LHS,
1/2 + 1/2x

Find the unknown coordinate so the line through the
points has the given slope
Answer:
#1 (0,-4)
#2 (5,0)
#3 (3,1)
Step-by-step explanation:
#1. (-3, 2) (0, y) slope = -2
slope = rise/run therefore slope = -2/1 or down 2 and over 1
so from -3 to 0 you are going over 3 units (or 3 times) Therefore to find y at x=0, you have to move three steps, or 3 times -2 = -6 so 2-6 = -4
so y intercept (b) = -4 0r (0,-4)
#2 (-7,-4) (x,0) slope (m) = 1/3 -7+12=5 x=5
#3 (4,-3) (x, 1) slope (m) = -4 (4/-1) Moving one unit in slope means
-3=4=1 for Y and 4-1=3 for X therefore the point is (3, 1)
Jessica is in an art lesson. She decides to pick a coloured pencil from her pencil case at random for her next drawing.
She has 10 coloured pencils in her pencil case, and 8 of them are yellow. What is the probability, as a percentage (%), that she picks a yellow pencil?
The probability that Jessica picks a yellow pencil is 80%.
What exactly is probability?
Probability is a measure of an event's possibility or chance of occurring. It is stated as a number ranging from 0 to 1, or as a percentage ranging from 0% to 100%, where 0 indicates an impossible occurrence and 1 (or 100%) represents a certain event.
Now,
The probability of picking a yellow pencil = the number of yellow pencils / total number of pencils:
Probability of picking a yellow pencil = Number of yellow pencils / Total number of pencils
In this case, there are 8 yellow pencils out of a total of 10 pencils:
Probability of picking a yellow pencil = 8 / 10
Simplifying the fraction by dividing both the numerator and denominator by 2, we get:
Probability of picking a yellow pencil = 4 / 5
Probability of picking a yellow pencil = 4 / 5 x 100%
Probability of picking a yellow pencil = 80%
Therefore, the probability that Jessica picks a yellow pencil is 80%.

Option • 12 is the answer .The number of treatments in the experiment is 12.
The understudy is directing a trial to comprehend the connection between microwave power and time on the quantity of unpopped bits in a pack of popcorn. There are three degrees of microwave power: low, medium, and high. Each sack of popcorn can be popped for either 3 minutes or 4 minutes, which provides us with a sum of double cross variables. To cover every one of the potential mixes of time and power, the understudy runs 12 distinct medicines (3 degrees of force x 2 degrees of time). Every treatment addresses one sack of popcorn that is popped for a particular time frame and with a particular power setting. The quantity of unpopped parts is recorded for every treatment, and the outcomes are utilized to make determinations about the impacts of microwave power and time on the quantity of unpopped pieces.

hello
to solve this problem, we will first of all find 6.5% in $9.00
this would be the cost or rate of the tax
\(\begin{gathered} 6.5\text{ \% of 9.0} \\ \frac{6.5}{100}=\frac{x}{9.0} \\ x=\frac{9.0\times6.5}{100} \\ x=0.585 \end{gathered}\)the cost of the tax is $0.585
the total cost of the purchase is the sum of the cost of the chew toy plus the tax
\(9.0+0.585=9.585\)Kane spent $9.585 in the store

URGENT: Given the following information about an ellipse, write its equation: Foci: (3, 1), (3, 5) Endpoints of minor axis: (7, −2), (–1, −2)
The equation of the ellipse is \((x - 3)^2 / 16 + (y - 3)^2 / 64 = 1.\)
To determine the equation of the ellipse, we need to find its major and minor axes, as well as the distance from each focus to the center.
Given that the foci of the ellipse are located at (3, 1) and (3, 5), we can determine that the center of the ellipse is at the midpoint between these two foci, which is (3, 3).
The endpoints of the minor axis are (7, -2) and (-1, -2), which tells us that the length of the minor axis is 7 - (-1) = 8 units.
Now, let's calculate the distance from the center to one of the foci. Using the distance formula, we have:
sqrt((3 - 3)^2 + (3 - 1)^2) = sqrt(0 + 4) = 2.
Since the foci are vertically aligned, the major axis is vertical. Therefore, the length of the major axis is twice the distance from the center to one of the foci, which gives us 2 \(\times\) 2 = 4 units.
Using the standard form of the equation for an ellipse centered at (h, k), with a horizontal major axis of length 2a and a vertical minor axis of length 2b, the equation is:
\((x - 3)^2 / 4^2 + (y - 3)^2 / 8^2 = 1.\)
