Can soomeone help me on this one too
Answer:
70°
Step-by-step explanation:
An euclidean triangle (a triangle on a straight plane) has sum of three angles equal to 180°.
When we talk about a triangle, we usually talk about an euclidean one.
There are also a non-euclidean triangles which are a triangle on circular plane which has sum of angles above 180° and one that is a hyperbolic triangle version which has sum below 180°.
Back to the question, since we know that the triangle is an euclidean one and thus has the sum equal 180°.
x+20+40+2x-30 = 180
Combine like terms:
3x+30=180
Subtract both sides:
3x+30-30=180-30
3x=150
Divide both sides by 3.
3x/3 = 150/3
x = 50
Since we want to find angle B which has measure of 2x-30, substitute x = 50 in 2x-30.
2(50)-30 = 100-30 = 70
Therefore angle B is 70°

The seventeen students on the Math Team want to raise $500 to buy practice books. They have already raised $234.63. If each student raises the same amount, how much more money must each student raise?
Answer:
Roughly $29.50 dollars.
Step-by-step explanation:
To find the answer you would
500 ÷ number of students
to find how much every student should raise.
500 ÷ 17 = 29.41
If we round out to make it simpler, each student must raise $29.50.

Ann made $143 for 11 hours of work.
At the same rate, how many hours of work would she have to work to make $243
Answer:
22 hours
Step-by-step explanation:
So, 143 equals eleven hours. 143 plus 143 would equal 243. So, you have two 143s which means you should multiply the 11 hours by two. 11x2 equals 22.
is y=x2-1 a linear function
Answer:
No, it is a quadratic function
Step-by-step explanation:
If you mean y=x²-1, then it is a quadratic, since we have x to the 2nd power.
If we had an equation in the form of y=mx+b, where m is the slope and b is the y intercept, it is linear.
An example of a linear function would be, y=6x-5
Which offer results in the cheapest cake: 8 cakes for £3.20 or 5 cakes for £1.90. Explain your answer
Answer:
5 cakes for 1.90 (i dont have pounds symbol)
Step-by-step explanation:
To find the cheapest cake, divide both numbers (3.20, 1.90) by the number of cakes (8, 5)
3.20 ÷ 8 = 0.4 per cake
1.90 ÷ 5 = 0.38 per cake

Step-by-step explanation:
The x-intercepts and vertex of the quadratic relation y = –(x + 3)(x + 5) are:
a) x-intercepts are 3 and 5; vertex is (4, 0)
b) x-intercepts are –3 and –5; vertex is (–4, 9)
c) x-intercepts are 3 and 5; vertex is (4, –63)
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Answer:
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Step-by-step explanation:
parabola are the vertex findings -4
we find these using formula m +n / 2
m+ n = -3 -5 / 2 = -4
m+n / 2 = -8/2 = -4
xv = -4
plug in -4 to find yv
(x+5)
(-4 + 5)
yv = 1
A regular octagon is shown below. Suppose that the octagon is rotated clockwise about its center so that the vertex at Y is moved to 7. How many degrees
does the octagon rotate?
Answer:
I believe it says the vertex at Y is moved to T:
the angle of each side changes by 360 / 8 = 45 at each vertex
If 3 vertices separate Y and T the the total rotation would be
3 * 45 = 135 deg
The octagon rotated 135 degree.
What is an Octagon?An octagon is a polygon with eight sides.
The total angle at the center is 360 degree and for a regular octagon, the angle made by each side is equal to 360/8 = 45 degree.
The octagon STUVWXYZ is rotated clockwise such that, the vertex Y moves to T.
Movement of Y to T is moving 3 steps clockwise
= 45* 3
= 135 degree
