Answer:
Think about it this way:
triangle KDI is supplementary to EHK. SO if we find the angles of KDI we can do the same for EHK. Additionally, the m<H in the triangle HKF is 90 degrees and since it is supplementary to EHK then the measure of h in EHK is also 90 degrees. So m<h is 90. All three angles will equal to 180 since the interior angles of any triangle equal 180°
Now, lets find the measures of KDI so we can solve for the measure of K in the triangle EHK
D in KDI is 19 degrees and the square on I in KDI indicates its a 90 degree angle. Those add up to 109 degreess meaning measure of k must equal 71 degrees (180=109=71) since the interior angles of any triangle equal 180. Therefor in the triangle EHK, h is 90, and k is 71 degrees by vertical angles theorem. 90 and 71 add up to 161 degrees meaning angle E is going to be equal to 19 (180-161=19). this, therefore means 17x-7=19
solve:
17x-7=19
17x=26
x=26/17
x=1 9/17
You can write it as a decimal, improper fraction or mixed number.

The total U.S. apple production increased during the 1973-1988 period from 6.2 to 9.l billion pounds. To the nearest tenth of a percent, what was the percent of increase in apple production in the United States from 1973-1988? plzzzzz help
Answers
Subtract to find the difference in the amounts:
9.1 - 6.2 = 2.9
Divide the change by the starting amount:
2.9/6.2 = 0.46774
Multiply by 100 to get the percentage and round to the nearest tenth:
0.46774 x 100 = 46.8 %

What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus, we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto XYZ,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x, y, z will perfectly match with transformed ABC
Hence, The correct answer is vertex B to vertex Y

Suppose A gas station monitors how many bags of ice they sell along with the maximum daily temperature for 100 days. A gas station data analysis plots the data in a scatterplot with temperature, in degrees Fahrenheit, on the horizontal axis and the number of bags of ice sword on the vertical axis. She calculates a linear correlation coefficient of r= 0.9972. The mean Temperature is 83.8959 degrees Fahrenheit with a standard deviation of 11.2921 Degrees Fahrenheit. The mean number of ice bags sold is 70.3873 with a standard deviation of 27.8 913.
Answers
Answer:
hello your question is incomplete attached below is the complete question
answer :
a ≈ - 136
b = 2.46
Step-by-step explanation:
A) we apply the formula for slope in regression
b = r * [tex]\frac{Sy}{Sx}[/tex] --------- ( 1 )
where:
standard deviation (Sy) = 27.8913
standard deviation ( Sx ) = 11.2921
Linear correlation coefficient ( r ) = 0.9972
substitute given values into equation 1
b = 2.46
for intercept A
a = Y - b * X --------- ( 2 )
Mean number of ice bags sold ( Y )= 70.2873
b = 2.46
Mean temperature ( X )= 83.8959
substitute given values into equation 2
a = 70.2873 - ( 2.46 * 83.8959 )
= - 135.997
The equation y = 1.2x represents the rate, in beats per second, that Lee's heart beats. The graph represents the rate that Nancy's hear beats. Determine whose heart is beating at a faster rate.
Answers
Answer:
Nancy's heart rate is higher than Lee's heart rate.
Step-by-step explanation:
Equation for the heart beats of Lee is,
y = 1.2x
And the heart beats of Nancy is represented by the graph.
Higher the slope of the line = Faster the hear rate.
Slope of line represented by y = 1.2x,
m = 1.2
Similarly, slope of the line given in the graph = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{5}{4}[/tex]
= 1.25
Since, slope of the line representing Nancy's heart rate is greater than slope of the line representing Lee's heart rate.
Therefore, Nancy's heart rate is faster than Lee's heart rate.

Tom has a fair spinner with six sides. They are labelled red, red, blue, green, red, blue. Choose the word that best describes the likelihood that the spinner will land on a colour not green.
Answers
Answer:
It is MOST LIKELY NOT going to land on green.
Step-by-step explanation:
Since the spinner has 6 sides, the total possible outcome is 6. There are 3 reds, 2 blues and 1 green.
The probability that the spinner will land on a green is [tex]\frac{1}{6}[/tex]. But since we are looking for the probability that it won't land on green, we have [tex]1 $-$ \frac{1}{6} = \frac{5}{6}[/tex]
From here we can best describe the likelihood that the spinner will land on a colour not green as: it is MOST LIKELY NOT going to land on green

Part 3: y=8140.394, or 8,140 since it's rounding to the nearest mile
Answer:
See answers in explanation below
Step-by-step explanation:
1. 4298 + 426t = 6129 + 223t
2. Basically get into the graphing page and find "function" section then select "f(x) = mx + b", then graph f(x) = 426x + 4298 and f(x) = 223x + 6129
and find the answer at where these two lines intersect with each other, x=9.0197 (months)
3. sub x=9.0197 into any of the two equation and f(x) = 8140 (miles)
Simon wants to build a cube-shaped storage container that holds 125 cubic feet of water for some frogs he recently purchased.Using the formula, V=s3, where represents the volume of the container and represents its side length, find the length of one side of the container.
Answers
Answer:
Length of one side of the container = 5 feet
Step-by-step explanation:
Given:
V = s³
Where,
V = volume of the container
s = side length of the container
V = 125 cubic feet
Find s?
V = s³
125 = s³
Find the cube root of both sides
3√125 = 3√s³
5 = s
s = 5 feet
Length of one side of the container = 5 feet
Jayvie has a VIP membership to a movie theater, so she pays $27 a year and $6.00 for each movie she sees. Claire doesn't have a membership, so she pays $8.25 each movie she sees. Which equation shows when they will pay the same amount of money?
Answers
Answer:
27 + 6x = 8.25x
Number of movies (x) = 12
Step-by-step explanation:
Given that:
VIP membership :
Membership fee = $27 per year
Amount per movie = $6
Hence ;
Membership fee + (amount per movie * number of movies)
27 + 6x - - - (1)
Non member :
Amount paid per movie = $8.25
amount per movie * number of movies)
8.25x - - (2)
Let Numbe of movies = x
In other to pay the same amount of money :
Equate (1) and (2)
Equation :
27 + 6x = 8.25x
8.25x - 6x = 27
