Answer:
m<v= 60 degrees
m<x= 100 degrees
Step-by-step explanation:
1) First let's find the measure of angle v. Most of the time if none of the angles are known then it is impossible to find others. However, this specific triangle is an equilateral, which has special rules. We know this is an equilateral because all the sides have the same length. Equilaterals will always have angles with measures of 60 degrees. This is due to the fact that sides and angles are proportionate. Therefore, if all the sides are the same, then the angles must be as well and 180 divided by 3 is 60.
2) Then, we can find the next measurement. This triangle is isosceles. Isosceles triangles have 2 equal sides and angles. The triangle represented above has 2 congruent sides; therefore, the base triangles must also be congruent. So we know that angles Y and W are 40. To find angle X make the expression 180-(40+40). This means that angle x must be 100 degrees.
Write the decimal in expanded form using fractions
0.801 = ???
Answer: 8/10 + 1/1000
Step-by-step explanation: in decimal form we have 0.800 + 0.001
to convert this into a fraction you'd do 8/10 + 1/1000
(8 is in the tenths place therefore 8/10 and 1 is in the thousandths place therefore 1/1000)

Answer:
(y²)³ = y⁶
Step-by-step explanation:
The power of a power rule is generally shows expressions where a power is being raised by another power. In such expressions, the exponents are multiplied together and the base is kept the same, like:
[tex] \qquad \qquad\boxed{ \sf{ { {(x}^{m}) }^{n} = {x}^{mn} }}[/tex]
In order to write the expression (y²)³ in the form of yⁿ, you may use this rule (power of a power rule) to obtain the answer.
[tex]\qquad \quad \sf{ { {(y}^{2}) }^{3} = {y}^{2(3)} = \pmb {\red{ {y}^{6}}}}[/tex]
How many petals p would there be in a group of 11 flowers ? Write an equation to find the unknown. Then find the unknown.
Answer:
11
Step-by-step explanation:
The required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.
Given that,
To determine how many petals p would there be in a group of 11 flowers.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number of petals in the single flower is n,
The total number of petals among the 11 flowers is p,
p = n11
Thus, the required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.

A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.
Answer: y = 4x-23
Step-by-step explanation: I'm assuming the question asks: "A line passes through the point (4, - 7) and has a slope of 4." I had difficulty understanding the format of the question. Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We can start with y = 4x + b, since we are given the slope. We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.
y = 4x + b
-7 = 4(4) + b
-7 = 16 + b
b = - 23
The equation is y = 4x-23

Graph the line that represents the equation
y+2=1/2 (x+2)
Answer: your answer is correct because if you put that equation into y=mx+b form you get y=1/2x-1
so you start at -1 and go over 2 and up 1 and you woulld land on 2
so you would graph at (2,-1) i think
