47°, 116°, 17°Step-by-step explanation:
Given angle measure of a triangle:
m∠V = (3x - 4)°m∠W = (7x - 3)°m∠X = x°Interior angles in a triangle sum to 180°, use the equation and solve for x:
3x - 4 + 7x - 3 + x = 18011x - 7 = 18011x = 187x = 187/11x = 17Find the values of angles:
m∠V = (3x - 4)° = (3*17 - 4)° = 47°m∠W = (7x - 3)° = (7*17 - 3)° = 116°m∠X = x° = 17°Related Questions
a wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. find the speed of the boat as she paddles the lake if the river current is 2 km/h
Answers
Answer:
6 km/hr or 5 km/hr
Step-by-step explanation:
In the lake, she goes 15 km at x km/hr (named)
In the river, she goes 6 km at x-2 km/hr (current=2 km/hr)
So, the time in the lake - the time in the river = 1 hour (given)
15/x - 6/x-2 = 1 --> x=6;x=5
The speed of the boat as the photographer paddles the lake if the river current is 2 km/h is 6 km/hr and this can be determined by forming the quadratic equation.
Given :
A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km.Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake.She paddles across the lake for one hour longer than she paddled up the river.According to the given data, if the river current velocity is 2 km/hr then let the speed in the lake be x km/hr. So, the speed of the photographer in the river is (x - 2) km/hr
Therefore, the speed of the boat as she paddles the lake if the river current is 2 km/h is given by:
[tex]\dfrac{15}{x} - \dfrac{6}{x-2}=1[/tex]
Now, simplify the above expression.
[tex]15(x-2)-6(x)=x(x-2)[/tex]
[tex]15x-30-6x=x^2-2x[/tex]
[tex]x^2-11x+30=0[/tex]
Factorize the above equation.
[tex]x^2-6x-5x+30=0[/tex]
x(x - 6) - 5(x - 6) = 0
(x - 6)(x - 5) = 0
x = 6 or 5

Tiffany has a job at the Best Bite Restaurant making $8 per hour. She earned $25 for the training shift. Find the rate of change and initial value. Write an equation.
Answers
Answer:
Initial value: $25; Rate of change: 48; Equation: y= 8x + 25
Step-by-step explanation:
The initial value would be the $25 due to the fact that that's how much money she made during training. After that, her money will go up by $8 for every hour she works for, which is why that's the rate of change.
The equation just restates all that, the rate of change is always represented by the mx in the equation (8 replaces the m), and 25 replaces the b, the start of the line, or on a graph, where the initial dot would be on the y-axis.

Answers
Given:
The two ways table.
To find:
The number of girls in year 9.
Solution:
Using the two ways table, we get
Boys in year 10 = Total student in year 10 - Girls in year 10
= 256 - 123
= 133
Boys in year 9 = Total boys - Boys in year 10 - Boys in year 11
= 407 - 133 - 125
= 149
Girls in year 9 = Total students in year 9 - Boys in year 9
= 303 - 149
= 154
Therefore, the number of girls in year 9 is 154 and the correct option is C.

What is the equation of the line that passes through the point (-3, 2) and
has a slope of -3?
Answers
Answer:
y= -3x -7
Step-by-step explanation:
You can either use y= mx+b or y-y1=m(x-x1)
I will use y= mx+b
y=mx+b
(-3,2) = (x,y) = -3 is x and 2 is y
-3 =m= slope
y=mx+b
2=-3(-3)+b
2= -3 x-3 +b
2= 9+b
you then subtract 9 on both sides because now 9 is positive so you subtract it.
2=9+b
-9 on both sides
-7= b and the final answer is above

Answer:
B
Step-by-step explanation:
Remark
I have to represent f(x) as plus +f(x)
I like to show this situation as +f(g(x)) which I think is much clearer.
+f(x) = 5x - 4
Solution
+f(g(x)) = 5(g(x)) - 4 What has happened is that wherever you see an x on the right you put in g(x).
Now on the right, you put whatever g(x) is equal to.
+f(g(x)) = 5(x^2 - 1) - 4
Remove the brackets.
+f(g(x)) = 5x^2 - 5 - 4
And make x = 0
+f(g(0)) = 5*0 - 5 - 4
+f(g(0)) = - 9

mrs.gretta is teaching a 5th grade class. She is standing 12 meters in front of ethan. isabella is sitting to ethans right. if isabella and mrs.gretta are 15 meter apart how far apart are ethan and isabella?
Answers
Answer:
Ethan and Isabella are 9 meters apart.
Step-by-step explanation:
1. We can solve this using the Pythagorean Theorem, a²+b²=c².
2. Mrs. Gretta is standing 12 meters in front of Ethan, so a=12.
3. Isabella is sitting to Ethan's right, but we don't know how far away, so b=x.
4. Mrs. Gretta is 15 meters from Isabella, so c=15.
5. Plugging these variables into the equation, we get 12²+x²=15² which equals 144+x²=225.
6. We can move 144 to the other side to get x²=81, then square the 81 to get x=9.
7. Therefore, the answer is 9. Ethan and Isabella are 9 meters apart.
How does the volume of a sphere with a radius 2 cm compare to the volume of a sphere with a radius 1 cm?
Answers
Explanation: The volume of a sphere is 4/3πr^3.
To compare the two volumes, we can simply subtract the smaller volume from the larger one.
(4/3*π*2^3)-(4/3*π*1^3)=29.32153=29.3.
