Which is the best estimate of the product of the fractions
please help! i'll give brainiest :)
Answer:
1. 109
2. 29
3. 71
Step-by-step explanation:
1. since a triangle's interior angles always add up to 180, you can add 35 and 36 to get 71, then subtract that from 180 to find the third angle
2. the unnamed angle in triangle RUV is supplementary to <1.Supplementary angles are angle the add up to 180. So you can subtract 109 from 180 to find the unnamed angle. It is 71. Now you can repeat the steps in question one to find <2 in triangle RUV. You get that <2 is 29
3. Angle 3 and the unnamed angle are vertical angles. This means that they are opposite to each other and are congruent. This means that they have the same measure. Knowing that the unnamed angle is 71, we can say that angle 3 is also 71.

What is the sum of the first 100 odd numbers? Start with adding the first 2, 3, 4 odd numbers.
Answer:
The sum of the first 100 odd numbers is 10,000
Step-by-step explanation:
Here, we want to find the sum of the first 100 odd numbers
Mathematically, we can use the formula for the sum of term in a sequence which is;
Sn = n/2(a + L)
where n is the number of terms
L is he last term
a is the first term
The difference between two consecutive odd numbers is 2
So:
T100 = 1 + (100-1)2
T100 = 1 + 198
T100 = 199
So;
sn = 100/2(1 + 199)
Sn = 50(200)
Sn = 10,000
Step-by-step explanation:
the sum of the first 100 odd numbers 10000

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What are the restrictions on the domain of (u circle v) (x)?
u(x) Not-equals 0 and v(x) Not-equals 2
x Not-equals 0 and x cannot be any value for which u(x) Equals 2
x Not-equals 2 and x cannot be any value for which v(x) Equals 0
u(x) Not-equals 2 and v(x) Not-equals 0
Answer:
The domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].
Hence, the restrictions would be:
[tex]x\:\ne \:2[/tex]and
[tex]v\left(x\right)\:\ne \:0[/tex]Step-by-step explanation:
Given
The domain of u(x) is the set of all real values except 0.
so
domain = (-∞, 0) U (0, ∞)
The domain of v(x) is the set of all real values except 2.
so
domain = (-∞, 2) U (2, ∞)
For the function composed function (u circle v) (x), we need to apply first the function [tex]v(x)[/tex] whose argument is (x), and then the function [tex]u (v(x) )[/tex] whose argument is [tex]v(x)[/tex].
Please note that the domain of the composed function (u circle v) (x) must have to take into account the values for which both functions u(x) and v(x) are defined.
Therefore, the domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].
Hence, the restrictions would be:

what are the zeros of f(x)=(x-1)(x+6)
Answer:
x = - 6, x = 1
Step-by-step explanation:
To find the zeros, let f(x) = 0, that is
(x - 1)(x + 6) = 0
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 1 = 0 ⇒ x = 1

The graph represents the number of cups of flour for the number of cups of sugar in a cake recipe. Using the graph, which of the following is a correct amount of flour and sugar?
A) 2 cups of flour: 1 1/2 cups of sugar
B) 1 1/2 cups of flour: 1 cup of sugar
C) 5 cups of flour: 3 cups of sugar
D) 1 1/2 cups of flour: 2 1/4 cups of sugar
Answer: B) 1 1/2 cups of flour: 1 cup of sugar
Step-by-step explanation:
When you look carefully at the graphed line, it intersects the grid at 1 1/2 on the vertical scale for Flour and at the same point, it intersects the 1 on the horizontal scale for Sugar. That is answer B.
Answer A is a close miss! When you follow the grid line across from 2 on the vertical scale, you see that the graphed line crosses it at just a little less than 1 1/2.

Pattern: Each x value is multiplied by 65
to get each y value.
Answer:
Equation: y = 65x
Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.
Step-by-step explanation:
Pick any two points to find slope, let's got with (3, 195) and (4, 260):
slope m = (y₂- y₁) / (x₂ - x₁)
= (260 - 195) / (4 - 3)
= 65 / 1
m = 65
Find y-intercept by using m from above and another point from your table, let's go with (5, 325):
y = mx + b
325 = 65(5) + b
325 = 325 + b
b = 0
Use m and b to form equation of line:
y = mx + b
y = 65x + 0
y = 65x
Check:
point (3, 195): 195 = 65(3) ====> 195 = 195
point (4, 260): 260 = 65(4) ====> 260 = 260
point (5, 325): 325 = 65(5) ====> 325 = 325
point (6, 390): 390 = 65(6) ====> 390 = 390
Example of a point that doesn't belong on table:
point (8, 500): 500 = 65(8) ====> 500 ≠ 520
The equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The table shows a representation of the number of miles a car drives over time. Hours, x
The equation of the line:
y - 195 = (260-195)/(4-3)[x - 3]
y - 195 = 65(x - 3)
y = 65x - 195 + 195
y = 65x
Plug x = 8
y = 195(8) = 1560
Thus, the equation of the line is y = 95x option (D) and the point (8, 445) is not on the line option (B) is correct.
The missing options are:
What is the equation for this situation?
y = 195x +3y = 195xy = 65x +3y = 65xWhich could NOT be a point on this table?
