Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
x = 121°
Step-by-step explanation:
The formula to find the sum of interior angles of a polygon is:
180 ( n - 2 )
Here,
n ⇒ number of sides ⇒ 7
First, let us find the sum of the interior angles of the polygon.
180 ( n - 2 )
180 × ( 7 - 2 )
180 × 5
900°.
Accordingly, let us make an expression to find the value of x.
145 + 133 + 140 + 125 + 119 + 117 + x = 900
Let us solve for x now.
779 + x = 900
Subtract 779 from both sides.
x = 900 - 779
x = 121

Drag number to the blanks to write a quadratic function, f(x), that has zeros at x = 2 and x = 6. f (x) = x2 + ___ x + ___
Answers
Answer:
f(x) = x² - 8x + 12
Step-by-step explanation:
Given the zeros are x = 2 and x = 6 then the corresponding factors are
(x - 2) and (x - 6)
The function is then the product of its factors
f(x) = (x - 2)(x - 6) ← expand using FOIL
f(x) = x² - 8x + 12

Answer:
x = 7
Step-by-step explanation:
The Triangle Sum Theorem tells us that the sum of the measures of a triangle's interior angles is 180. Using this information, we can make an equation to solve for x.
82 + 9x - 6 + 6x - 1 = 180
75 + 15x = 180 (Combine like terms)
15x = 105 (Subtract 75 from both sides)
x = 7 (Divide both sides by 15)
We can plug the value of x back into the equation to make sure of this answer.

Alice earns £450 in wages per month.
She pays £200 rent per month.
Next month.
her wages will increase by 2%
her rent will increase by 5%
She says
"The increase in my wages will pay for the increase in my rent."
Is she correct?
You must show your working.
Answers
Answer:
false
Step-by-step explanation:
Since in the question it is mentioned that the wages would be increased by 2% and rent would increase by 5%
So, the increased value of both is
= $450 × 1.02
= $459
And,
= $200 × 1.05
= $210
As the wages are increased to $9 and the rent is increased to $10 since the amount is not equivalent to each other so the given statement is false

A store has a 20% off sale on pants. The price of the pants before the discount was $48.
What was the sale price of the pants?
Answers
Answer:
$38.40
Step-by-step explanation:
20% of $48 is 9.60
48- 9.60= 38.40
Answer:
$38.40
Step-by-step explanation:
1. convert the percentage into a decimal by dividing x/100.
20/100 = 0.2
2. multiply by the original price.
0.2 * 48 = 9.6
3. subtract the discount.
$48 - $9.60 = $38.40

Step-by-step explanation:
The total cost of renovation depends on labor and materials. You decide to budget $25,000 towards labor. The amount, A, that each worker earns varies inversely to the number of workers on the job, n.
1) complete the table to indicate the amount earned for the given number of workers.
2) what do you notice about the product, A*n?
Answers
Answer:
see attachedA*n is the constant 25000Step-by-step explanation:
1)The amount A is said to vary inversely with n, so the equation relating the two is ...
A = k/n
The value of k can be found by multiplying this equation by n:
k = nA
Using values from the first line of the table, we find ...
k = (1)(25000) = 25000
So the relation we need to use to fill the table is ...
A = 25000/n
The filled table is attached.
__
2)As we saw in part 1, the product A*n is the constant of proportionality. It is a constant.
Find a and b given f(x) = ax + b, f(1) = 7, and f(3) = -5.
Answers
Answer:
a = - 6, b = 13
Step-by-step explanation:
Given f(1) = 7 , that is f(x) = 7 when x = 1
f(3) = - 5 , that is f(x) = - 5 when x = 3
Substitute these values into f(x) = ax + b
a + b = 7 → (1)
3a + b = - 5 → (2)
Subtract (1) from (2) term by term to eliminate b
(3a - a) + (b - b) = - 5 - 7
2a = - 12 ( divide both sides by 2 )
a = - 6
Substitute a = - 6 into either of the 2 equations and solve for b
Substituting into (1)
- 6 + b = 7 ( add 6 to both sides )
b = 13

Answers
Answer/Step-by-step explanation:
Given:
m<4 = 131°
a. m<8 = 180 - m<4 (linear pair)
m<8 = 180 - 131 (substitution)
m<8 = 49°
b. m<5 = m<4 (alternate exterior angle are congruent)
m<5 = 131° (substitution)
c. m<2 = m<5 (vertical angles are congruent)
m<2 = 131° (substitution)
d. m<1 = m<8 (vertical angles are congruent)
m<1 = 49° (substitution)
e. m<6 = m<1 (vertical angles are congruent)
m<6 = 49° (substitution)
f. m<7 = m<4 (vertical angles are congruent)
m<7 = 131° (substitution)
