Step-by-step explanation:
take 60 degree as reference angle
using cos rule
cos 60=adjacent/hypotenuse
1/2=80/x(do cross multiplication)
80*2=x
160=x
Answer:
x = 160
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{CD}{CE}[/tex] = [tex]\frac{80}{x}[/tex] ( multiply both sides by x )
x × cos60° = 80 ( divide both sides by cos60° )
x = [tex]\frac{80}{cos60}[/tex] = 160

Determine the x-and y-intercepts.
-5x + 2y = 10
Answers
Answer:
The x intercept is -2
The y intercept is 5
Step-by-step explanation:
-5x + 2y = 10
To find the x intercept set y =0 and solve for x
-5x + 0 = 10
-5x = 10
x = 10/-5 = -2
The x intercept is -2
To find the y intercept set x =0 and solve for y
0 + 2y = 10
2y = 10
y = 10/2 = 5
The y intercept is 5
Y=10
-5x2=-10
2x10=20

2 intersecting lines are shown. A line with points T, R, W intersects a line with points S, R, V at point R. Angle T R V is 95 degrees. mAngle SRW = °
Answers
Answer:
m<SRW = 95degrees
Step-by-step explanation:
If a line with points T, R, W intersects a line with points S, R, V at point R with the point of intersection at R, this means that;
m<TRV = m<SRW (vertically opposite angles)
Since m<TRV = 95 degrees, hence <SRW = 95degrees
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?
Answers
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
Find the coordinates of the vertices of the figure after the given transformation: T<0,7>
Answers
Answer:
Option A.
Step-by-step explanation:
The general transformation works as follows:
T<a,b>(x, y) = (x + a, y + b)
Then for our transformation, we will have:
T<0,7>(x, y) = (x, y + 7)
So now that we know how the transformation works, we need to apply it to the vertices.
Looking at the graph we can see that the vertices are:
X = (-4, -5)
W = (-3, -3)
L = (-5, -2)
Then the new points will be:
X' = (-4, - 5 + 7) = (-4, 2)
W' = (-3, -3 + 7) = (-3, 4)
L' = (-5, -2 + 7) = (-5, 5)
Then the correct option is A.

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
Answers
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

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.
Answers
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.
