Step-by-step explanation:
Given triangle PRS is congruent to triangle CFH, find the values of x, y, and z.
Answer:
x = 23
y = 7
z = 11
Step-by-step explanation:
Since ∆PRS ≅ ∆CFH, therefore,
m<R = m<F
13y - 1 = 90° (substitution)
Add 1 to both sides
13y - 1 + 1 = 90 + 1
13y = 91
Divide both sides by 13
13y/13 = 91/13
y = 7
Since ∆PRS ≅ ∆CFH, therefore,
PS = CH
2x - 7 = 39 (substitution)
Add 7 to both sides
2x - 7 + 7 = 39 + 7
2x = 46
Divide both sides by 2
2x/2 = 46/2
x = 23
Since ∆PRS ≅ ∆CFH, therefore,
m<S = m<H
Find m<S
m<S = 180 - (m<P + m<R) (sum of ∆)
m<S = 180 - (28 + (13y - 1)) (substitution)
Plug in the value of y
m<S = 180 - (28 + (13)(7) - 1))
m<S = 180 - (28 + 91 - 1)
m<S = 180 - 118
m<S = 62°
Therefore, since m<S = m<H,
62° = 6z - 4 (substitution)
Add 4 to both sides
62 + 4 = 6z - 4 + 4
66 = 6z
Divide both sides by 6
66/6 = 6z/6
11 = z
The values of x, y, and z are;
x = 23
x = 23y = 7
x = 23y = 7z = 11
We are told that triangle PRS is congruent to triangle CFH.
Since both triangles are congruent, by inspection we can see that;
m<R = m<F
m<F is a right angle = 90°. Thus;
13y - 1 = 90
13y = 90 + 1
13y = 91
y = 91/13
y = 7
Also by inspection;
PS = CH
2x - 7 = 39
2x = 39 + 7
2x = 46
x = 46/2
x = 23
Since m<R is 90°, then;
m<S = 180 - (90 + 28)
m<S = 62°
By inspection;
m<S = m<H
Thus;
6z - 4 = 62
6z = 66
z = 66/6
z = 11

George is 3 years older than the quotient of Joseph's age and 2. Letj represent joseph's age. Write an expression in the box
that would show George's age
Answer:
j/2+3
Step-by-step explanation:
Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.
Then it says that George is 3 years older, so that would be addition.
Therefore, it would be:
x/2+3
If a rectangular prism has a base area of 14 square centimeters and a height of eight centimeters, what is the volume?
Answer:
The volume is 112 cm³
Step-by-step explanation:
I think it's 112 because to find the volume of a rectangular prism you must multiply the length* width* height and 14 the base( base =legth*width) multiplied by 8 equals 112 cm³

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour? Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.? Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
Answer:
She rode 17.4 miles in 1 hour
Step-by-step explanation:
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?
The quotient is the average speed and this is calculated as:
Speed = Distance(miles)/Time(hours)
Where speed = quotient
Distance = Dividend
Time = Divisor
Speed = 60.9 miles/3.5 hours
= 17.4 miles/hour
Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
If :
3.5 hours = 60.9 miles
1 hour = x miles
Cross Multiply =
3.5x = 60.9 miles
x = 60.9/3.5
x = 17.4 miles
Hence, she rode 17.4 miles in 1 hour

the bearing of a plane from the airport is 65.
Calculate the bearing of the airport from the plane
Answer:
The bearing of the airport from the plane is 245°
Step-by-step explanation:
The bearing of a point from a location is given by the angle in degrees of rotation from the Northern direction of the location to the direction of the location of the point
The given bearing of the plane from the airport = 65°
Therefore, the direction of the plane from the Northern direction of the airport = 65°
From the Northern direction of the plane, the bearing of the airport = 245°

Answer:
4
Step-by-step explanation:
We can see from the two marked points the coordinates are: (2, 8) and (4, 16)
That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.
Therefore slope = rise/run = 8/2 = 4.

What type of association is shown by the data in the scatter plot?
Answer Choices:
A. positive association
B. negative association
C. no association
D. trend association
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.does anyone know what -23= 13w+2w+22 is plz help!
Answer:
w = -3
Step-by-step explanation:
-23 = 13w + 2w + 22
Combine like terms (add 13w and 2w and subtract 22 from both sides)
-45 = 15w
Divide both sides by 15
w = -3
