anyone got an answer for this (don't mind the 160 i put. That answer is wrong)
Answer:
140°
Step-by-step explanation:
Angles in a triangle add up to 180
we can see it's an isosceles triangle so the base angles are the same
The missing angle inside the triangle would be...
180 - (70 + 70) = 40°
Angles on a straight line add up to 180
so 180 - 40 = 140°

0.98
D
D>
(b) 9.07 [ 9.3
?.
(c) 0,90 [ 0.9
Answer:
0.32, 0.45, 0.76.
Step-by-step explanation:
so first you would use your < >,= signs and compare all of them until you have eliminated ALL but one (so 0.91<0.98 this is because 0.98 is close to 1 whole than 0.91) and you would continue this explanation for so on

In the most simplest of terms, we can explain irrational numbers as numbers which cannot be expressed as a ratio of two integers usually because they cannot give an exact value when evaluated.
Using the values given :
6.7234724... - - >This is an irrational number because the '...' depicts that the values are unending and as such an exact expression in the form of a ratio (p/q) cannot be determined.

Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram.
Write the formula for the cost (y), in dollars, of g grams of saffron.*
a) y = 7.35g
b)g=7.35 y
c) y = 7.35+g
Answer:
A
Step-by-step explanation:
B is wrong because it's saying to multiply the cost by $7.35.
C is wrong because it's telling you to add the amount of grams to $7.35.
A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.
Saffron is one the most expensive spices in the world. Ms. Patel pays $123.51 for 2.3 grams of saffron. What is the price per gram?

13. Suppose a real estate agent receives 5%
commission on the fi rst $200 000 of a
house’s selling price, and 6% on the
remaining amount.
a) What does commission mean?
b) If a house sells for $345 000, how
much commission does the real estate
agent make on the sale of the house?
Answer:
Commision may be defined as a percentage cut which an employee, broker, vendor, retailer or other persons within a sale chain receive from an employer or production firm for selling a good or offering a successful service based on agreed terms by both parties. ;
$18700
Step-by-step explanation:
Given :
Commision pattern :
5% on first $200,000
6% on remaining amount
Amount of commission on $345000
0.05 * 200000 = 10,000
0.06 * (345000 - 200000) = 8700
Total commission :
10,000 + 8700 = 18,700

Answer:
A. d = 0 -- one (1) solution
B. x = {1, 3.5}
Step-by-step explanation:
A. The discriminant for ax²+bx+c = 0 is ...
d = b² -4ac
For the given equation, this is ...
d = (-36)² -4(9)(36) = 0
The discriminant is zero (0).
The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.
__
B. The equation can be factored as ...
2x² -9x +7 = (2x -7)(x -1) = 0
The solutions are the values of x that make the factors be zero:
2x -7 = 0 ⇒ x = 7/2
x -1 = 0 ⇒ x = 1
The solutions are x = 7/2 or x = 1.

what percent is 52.8 of 55? also how did u get itttt
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55
The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C.
Given:
The equation is
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
To find:
The length of the line segment AC.
Solution:
We have,
[tex]\tan(55^\circ)=\dfrac{15}{b}[/tex]
[tex]1.428148=\dfrac{15}{b}[/tex]
Multiply both sides by b.
[tex]1.428148b=15[/tex]
Divide both sides by 1.428148.
[tex]b=\dfrac{15}{1.428148}[/tex]
[tex]b=10.50311[/tex]
[tex]b\approx 10.503[/tex]
In a triangle ABC, the line of line segment AC is b. So,
[tex]AC\approx 10.503[/tex]
Therefore, the length of the line segment AC is 10.503 units.

6(x-4)-x=6x+4 one solution, no solution or infinite solution
Answer:
no solution
Step-by-step explanation:
Given
6(x - 4) = 6x + 4 ← distribute left side
6x - 24 = 6x + 4 ( add 24 to both sides )
6x = 6x + 28 ( subtract 6x from both sides )
0 = 28 ← not possible
This indicates the equation has no solution

Step-by-step explanation:
Given data
Company A
charges a fixed amount of $10 plus $8 per hour
let the number of hours be x
and the total be y
y= 10+8x----------------1
Company B
charges a fixed amount of $6 plus $10 per hour for a one-person kayak.

and the total be y
y= 6+10x----------------2
Equate 1 and 2 above
10+8x= 6+10x
collcet like terms
10-6= 10x-8x
4= 2x

From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

The statement that best explains the relationship between lines FG and HJ is "They are not perpendicular because their slopes are not negative reciprocals."
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the slope of a line passing through two given points, we use the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
For line FG, the two points are F(-4, 1) and G(0, -2):
slope of FG = (-2 - 1) / (0 - (-4)) = (-2 - 1) / 4 = -3/4
For line HJ, the two points are H(-4, -2) and J(0, 4):
slope of HJ = (4 - (-2)) / (0 - (-4)) = 6/4 = 3/2
The slopes of lines FG and HJ are not equal. However, we can see that they are not negative reciprocals of each other:
slope of FG = -3/4
slope of HJ = 3/2
Therefore, lines FG and HJ are not perpendicular because their slopes are not negative reciprocals of each other.

In the school chorus, 3 9 of the students are fourth graders. In simplest form, what fraction of the students in the school chorus are fourth graders?
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3
= (3/3) / (9/3)
