whats the angle of J
Answer:
<J = 59
Step-by-step explanation:
Since this is an isosceles triangle, <J and <H are the same
The sum of the angles in a triangle are 180
62+ <J + <H =180
62+ <J + <J = 180
62 + 2 <J =180
Subtract 62 from each side
2 < J = 180-62
2 < J = 118
Divide by 2
<J =118/2
<J = 59
Answer:
∠J = 59 °
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
so, ∠J and ∠H are same.
We know that sum of angles of triangle is 180°.∠J = ∠H .. ( in isosceles triangle two side are equal).
so, ∠J = ∠J
62° + ∠J + ∠ J = 180°
combine like terms
62° + ∠2J = 180°
Subtract 62 from each side
62° - 62° + ∠2J = 180° - 62°
∠2J = 118°
Divide each side by 2
∠2J/2 = 118° / 2
∠J = 59 °
Verification :-
∠J + ∠H + 62° = 180°
59° + 59° + 62° = 180°. .( ∠J =∠H - proved above)
118° + 62° = 180°
180° = 180°
LHS = RHS

syd is on a cliff 43 feet above sea level ingrid dove into the sea and took photos of fish at 17 feet below sea level how far apart are syd and ingrid?
Answer:
60 ft
Step-by-step explanation:
Position of Syd = +43
Position of Ingrid = - 17
To find the distance between them, add the absolute value
I +43 I + I-17I = 43 + 17 = 60
Answer:
let's take the postion of sea level 0
such that
syds on a cliff 43 ft above sea level
his position = 43 ft
Ingrid is 17 feet below sea level so his position = 17 ft in the opposite direction as that of Syd.
since syd is 43 feet away from sea level, that is 0, and sea level is 17 feet away from Ingrid.
distance between syd and Ingrid = 43 + 17
= 60 ft
You start driving west for 9 miles, turn right, and drive north for another 6 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
Answer:
10.8 mi
Step-by-step explanation:
Picture a right triangle with legs 9 mi and 6 mi. Applying the Pythagorean Theorem (d² = a² + b²), we get:
(9 mi)² + (6 mi)² = 117 mi²
This is the square of the hypotenuse (the desired distance).
Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d
The desired straight line distance traveled is 10.8 mi

What is the slope of the line that contains the points (14,-2) and (3,-2)
Answer:
0
Step-by-step explanation:
We can use the slope formula since we have two points
m = ( y2-y1)/(x2-x1)
= ( -2- -2)/(3-14)
= ( -2+2)/(3-14)
= 0/-11
= 0
Answer:
0 is the slope of the line that contains the points (14,-2) and (3,-2)
Step-by-step explanation:
We have two points which are ( 14 , -2) and ( 3, -2).To find , the slope is the slope of the line that contains the points (14 , -2)and (3, -2)
we using slope formula which is
m = ( y ² - y ¹ ) / ( x ² - x ¹)Where,
m , is the slope
( y ² - y ¹ ) = ( 14 , - 2)
( x ² - x ¹) = (3, -2 )
Substitute the values into the formula
m = (( -2 )- ( -2 ) ) / (3 - 14 )
m= ( -2 + 2 ) / ( 11)
m = 0 / 11
m = 0
Therefore , 0 is the slope of the line that contains the points (14,-2) and (3,-2)

The amount that two groups of students spent on snacks in one day is shown in the dot plots below.
Group A
A dot plot titled Group A. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.
Group B
A dot plot titled Group B. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 3 above 1, 2 above 2, 4 above 3, 0 above 4, and 1 above 5.
Which statements about the measures of center are true? Select three choices.
O The mean for Group A is less than the mean for Group B.
O The median for Group A is less than the median for Group B.
O The mode for Group A is less than the mode for Group B.
O The median for Group A is 2.
O The median for Group B is 3.
Answer:
A, B, and C
not D or E
Step-by-step explanation:
A: the mean is 1.6 for group A compared to 2.5 of group B
B: the median is 1.5 for group A compared to 2.5 of group B
C: the mode is 3 for A and the mode is 5 for B
therefor, abc :)
The three statements that are true about the measures of the centre are:
The median for Group A is 2.
The median for Group B is 3.
The mode for Group A is less than the mode for Group B.
What are the mode, median, and mean?We must tally up every dollar spent and divide it by the number of pupils in each group to determine the mean for each group.
The dot plots show that Group A is expected to have a mean that is lower than Group B because Group A has more values that are less than $2, which will lower the average.
Yet, based just on the dot plots, we cannot be certain of the precise values of the means. The claim "The mean for Group A is less than the mean for Group B" is therefore not always accurate.
When the data are organized in order, the median is the middle value. The dot plots show that Group A's median is 2 and Group B's median is 3, respectively. It follows that the claim "The median for Group A is less than the median for Group B" is untrue.
The value that appears the most frequently is the mode. The dot plots demonstrate that Group A has a mode of 1, while Group B has a mode of 3. The adage "The mode for Group A is less than the mode for Group B" is therefore accurate.

If the federal reserve decreases the reserve rate from 10% to 80% how does this affect the amount of money that would result because a fractional reserve banking from an initial deposit into a bank of $40,000
Answer:
100,000
Step-by-step explanation:
Given :
Initial deposit = 40000
Amount of money = Initial deposit / Reserve rate
When reserve rate = 10% = 0.1
Amount of money = 40000 / 0.1 = 400,000
When reserve rate = 8% = 0.08
Amount of money = 40000 / 0.08 = 500,000
Difference = 500,000 - 400,000 = 100,000
Amount of money will increase by 100,000

The first track is 95°. What is the angle between the road and the second track? Why?
[Hint: Draw a pair of parallel lines and a transversal]
=======================================================
Explanation:
I recommend drawing it out to see what's going on. See the drawing below.
In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees.
Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.
