Answer:
a) Area of wall to be painted = 114 sq ft
b) Number of cans required = 2×5 = 10
c) Total cost of paint = $338.43
Step-by-step explanation:
Part a)We are asked to find the area of wall that needs to be painted.
we need to subtract the area of window from the area of wall.
We know that area of a rectangular shape is given by
Area = Width×Length
Area of whole wall = 8×15 = 120 sq ft
Area of window = 2×3 = 6 sq ft
Area of wall to be painted = 120 - 6 = 114 sq ft
Part b)1 can of paint will cover 25 sq ft of area.
So to cover the area of wall to be painted,
114/25 = 4.56
since number of cans cannot be in fraction so we would need 5 cans
Since two coats of paints are needed so
Number of cans required = 2×5 = 10
Part c)1 can of paint costs $29.95
We have total 10 cans
$29.95×10 = $299.5
There is also a 13% tax so the total cost is
$299.5×0.13 = $38.93
Total cost of paint = $299.5 + $38.93
Total cost of paint = $338.43

Step-by-step explanation:
In Triangle A B C, what is the value of x? Triangle A B C. Angle A is 112 degrees. Exterior angle to angle B is 2 x degrees and the exterior angle to angle C is (2 x + 12) degrees.
Answer:
70°
Step-by-step explanation:
∠A =112°,
Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)
Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x
∠A + ∠B + ∠C = 180 (sum o angles in a triangle)
112 + 180 - 2x + 168 - 2x = 180
460 - 4x = 180
4x = 460 - 180 = 280
x = 280/4 = 70
x = 70°
Answer:
70º

Ratio of three angles of a triangle is 1 : 2 : 3. Find the angles.
Answer:
30⁰ , 60⁰ , 90⁰
Step-by-step explanation:
Let the angles x , 2x , 3x
By angle sum property:
x + 2x + 3x = 180⁰
6x = 180⁰
x = 30⁰
Angles are : 30⁰ , 60⁰ , 90⁰
Answer:
30°, 60°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide to find the value of one part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio, thus
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Thus angles are 30°, 60° and 90°

In the triangle below, what is the length of the side opposite the 60° angle?
Answer:
C. 3√3
Step-by-step explanation:
Remember your 30-60-90 triangle rules.
They give you 3 as a side in the 30-60-90. That side length 3 will be your x. The side opposite of it is x√3. Simply plug in 3 as it is x and you should get 3√3 as your answer.
Answer:
C
Step-by-step explanation:
In all 30 60 90 triangles, the side opposite the 60 degree angle will be the short leg times [tex]\sqrt{3}[/tex]
So, the length of that side in this triangle will be 3[tex]\sqrt{3}[/tex]

In a true-false test containing 50 questions, a student is to be awarded 2 marks for every correct answer and -2 for every incorrect answer and 0 for not supplying any answer. If Yash scored 94 marks in a test, what are the possibilities of his marking correct or wrong answer
Answer:
1. 47 correct, 0 wrong and 3 unanswered
2. 48 correct, 1 wrong and 1 unanswered
Step-by-step explanation:
Given;
Total number of questions = 50
For correct answers = 2
For wrong answers = -2
Unanswered questions = 0
Yash scored 94 marks
Let c, w and u represent the number of correct, wrong and unanswered questions
2×c - 2 × w + 0×u = 94
2c -2w = 94 .....1
And;
c + w + u = 50 .....2
We have 2 equations and 3 unknowns
By observing the problem, we can see two possible solutions;
Case 1: Assuming he did not miss (get wrong) any answer;
He needs to score 47 answers right;
47 × 2 = 94
Then;
c = 47 w = 0 and u = 50 - (47+0) = 3
47 correct, 0 wrong and 3 unanswered
Case 2: Assuming he got one answer wrong;
He would need to score one more answer right compared to the first case;
(47+1) × 2 - 1 × 2 = 96 - 2 = 94
c = 47+1 = 48
w = 1
u = 50 - (48+1) = 1
So he need to score 48 correct answers, 1 wrong answer and 1 unanswered.
the weights, in pounds, of the upper class men offensive line players for a college are shown below:
322, 290, 321, 326, 330, 315, 311, 292, 290
What is the average, or mean, weight of the upper-class men offensive players? provide your answer with 3 sig figs.
1) 311 pounds
2) 315 pounds
3) 290 pounds
4) 318 pounds
Answer:
311 pounds
Step-by-step explanation:
Here, we are to calculate the average weight of the upper-class men offensive players
To calculate this, we need to sum up all the weights and divide by their count
Mathematically, that would be;
Average weight = (322+290+321+326+330+315+311+292+290)/9 = 2,797/9 = 310.77778
Now this written in 3 significant figures would be 311 pounds
Answer:
311
Step-by-step explanation:
You add all of the numbers first (2797)
Then you divide by how many numbers there were (9)
You get 310.7778
Then you round with 3 sig figs.
That is 311

Write this equation in slope-intercept form. 5x - 6y = -6 *
Answer:
y = 5/6x +1
Step-by-step explanation:
5x - 6y = -6
We want the equation in the form
y = mx+b where m is the slope and b is the y intercept
Subtract 5x from each side
5x -5x - 6y =-5x -6
-6y = -5x -6
Divide each side -6
-6y/-6 = -5x/-6 -6/-6
y = 5/6x +1
A circle is centered at Q(1,-5) and has a radius of 5. Where does the point Y(4,-1) lie?
Answer:
Point Y (4, -1) lies on the circle.
Step-by-step explanation:
Distance = √[(x2-x1)² + (y2 - y1)²] = √[(4-1)² + (-1-(-5))²] = √[3² + 4²]= √25 = 5
Point Y (4, -1) lies on the circle, because the distance from the center to this point equals radius of the circle.
Answer:
On the circle

What is the sum of this arithmetic series?
Answer:
The sum of the arithmetic series
[tex]S_{n} = \frac{n}{2} (2 a + (n-1) d)[/tex]
Step-by-step explanation:
Explanation
Let a , a+d , a+2 d , ..........a+(n-1)d +....... is an arithmetic sequence
The sum of the sequence is called arithmetic series
The [tex]n^{th}[/tex] term of the sequence
[tex]t_{n} = a + (n-1) d[/tex]
The sum of the arithmetic series
[tex]S_{n} = \frac{n}{2} (2 a + (n-1) d)[/tex]
Here 'a' is the first term of the sequence
and 'd' be the difference between two values
sum of first term
put n=1 ⇒ [tex]S_{1} = a[/tex]
Put n =2 ⇒ [tex]S_{2} = \frac{2}{2} (2 a + (2-1)d)[/tex]
[tex]S_{2} = 2 a + d[/tex]
......and so on
The sum of the arithmetic series
[tex]S_{n} = \frac{n}{2} (2 a + (n-1) d)[/tex]

The measure of angle BOC is 42 degrees.
Answer:
BOC = 42º
Step-by-step explanation:
Angle BOC is equal to 42 degrees, due to these steps -
1. Create the equation which will result to be -
6x - 6 + 5x + 8 = 90
2. Simplify by adding variables and numbers together -
11x + 2 = 90
3. Subtract 2 from both sides to get -
11x = 88
4. Divide by 11 on both sides to get-
x = 8
5. Substitute x in angle BOC as 8 to get this equation -
6(8) - 6
6. Solve
48 - 6 =
42º
Your final answer for angle BOC is 42º!

Please answer this math question !! Thank u !! 20 POINTS AND BRAINLIEST!!
Answer:
infinite solutions
Step-by-step explanation:
Given the 2 equations
y = 6x - 3 → (1)
12x - 2y - 6 = 0 → (2)
Substitute y = 6x - 3 into (2)
12x - 2(6x - 3) - 6 = 0 ← distribute and simplify left side
12x - 12x + 6 - 6 = 0
0 = 0
This solution 0 = 0 indicates that any value of x is a solution
Thus there are an infinite number of solutions to the system

Mapiya writes a series of novels. She earned \$75{,}000$75,000dollar sign, 75, comma, 000 for the first book, and her cumulative earnings double with each sequel that she writes.
Answer:
[tex]E(n)=75000 \times 2^n[/tex]
Complete question:
write a function that gives mapiyas cumulative earnings E(n), in dollars when she has written n sequel's
Step-by-step explanation:
According to the question, she earned $75000 for the first book.
Also,We are given that her cumulative earnings double with each sequel that she writes.
Assuming she has written n sequel's
Now since we are given that her cumulative earnings double with each sequel
So, her initial earning will be [tex]2^n[/tex] times
So, her earning will be : [tex]75000 \times 2^n[/tex]
Now we are given that cumulative earnings is denoted by E(n)
So, the function becomes :[tex]E(n)=75000 \times 2^n[/tex]
Hence a function that gives Mapiya's cumulative earnings E(n), in dollars when she has written n sequel's is [tex]E(n)=75000 \times 2^n[/tex]
