Answer:
the answer is 11 because in a question like this you multiply first before anything, so 2x4 is 8 and then you have to add 8 by 3, which that equals to 11.
what is the percent decrease of 2,400 to 2,100?
#You times it with ×100 to get the percentage
#Part of the number/total number
2400 - 2100 = 300
300/2400 × 100 = 12.5%
So the percentage decreased is 12.5%
What is the sum of the interior
angles of a polygon that has 19
sides?
[?] degrees
Please helpppp!!!!!
Answer:
[tex]\boxed {\boxed {\sf 3060 \textdegree}}[/tex]
Step-by-step explanation:
The sum of a polygon's interior angles is found using this formula:
[tex]180 \textdegree (n-2)[/tex]
where n is the number of sides. This polygon has 19 sides.
[tex]n=19[/tex]
[tex]180 \textdegree*(19-2)[/tex]
[tex]180 \textdegree*(17)[/tex]
[tex]3060 \textdegree[/tex]
The sum of the interior angles is 3,060 degrees.

A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?
Let's assume the no. of chocolate pastry bought = x
and the no: of fruit pastry bought = y
➣ Cost of 1 chocolate pastry = Rs 26
➣ Cost of x chocolate pastry = Rs 26x
➣ Similarly, cost of fruit pastry = Rs 18 y
➣ It is given that the total cost = Rs 500
Therefore, Rs 26x + Rs 18 y = Rs 500
If we assume x = 4 and y = 22 , then
26 x 4 + 18 X 22 = Rs 500
104 + 396 = 500
⇝ No. of chocolate pastries bought = 4 ✔
⇝ No. of fruit pastries bought = 22 ✔

Find the mZNPI
Exterior angles of triangle
Given:
The figure of a triangle.
To find:
The exterior angle of the triangle m∠NPI.
Solution:
According to the exterior angle theorem, value of exterior angle of a triangle is equal to the sum of the opposite interior angles.
Using the exterior angle theorem, we get
[tex]m\angle NPI=65^\circ+78^\circ[/tex]
[tex]m\angle NPI=143^\circ[/tex]
Therefore, the measure of angle NPI is 143 degrees.

The missing dimension of the prism is A
because the volume of the rectangular prism equals the product of the sides, we have:
V = (x - 1)(x - 3)A
but V = x³ - 8x² + 19x - 12
=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A
⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A
⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A
⇒ A = x - 4

Answer:
C
Step-by-step explanation:
First we need to find W. You can do that by dividing 47.25 by 5.25.
47.25 / 5.25 = 9
So W = 9.
Now we do both equations to see which one is correct.
Equation A: 3/4 × 9 = 6 3/4, which is true.
Equation B: 9 - 10.24 = -1.24, which is also true.
Therefore, both equations give you the same solution, C.

Step-by-step explanation:
Ryan buys some jumpers to sell on a stall. He spends £130 buying 80 jumpers. He sells 75% of the jumpers for £9 each. He then puts the rest of the jumpers on a Buy one get one half price offer. He manages to sell half the remaining jumpers using this offer. How much profit does Ryan make?
Answer:
£477.5
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Total jumper bought = 80
Total spends = £130
Now, first sell 75% of jumper for £9 each, then
75% × 80 = 60
So, 60 × £9 = £540
Remaining jumper = 80 - 60 = 20
Selling half of remaining, 20÷ 2 = 10
Selling 10 jumper = (5 × £9) + (5 × £4.5 ) ( buy one get one half price)
Income of 10 = £45 + £22.5 = £67.5
So, total income by selling 70 jumpers = £540 + £67.5 = £607.5
Hence, Profit = £607.5 - £130
= £477.5

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Tell whether the conditional and its converse form a biconditional:
Any fraction is in the simplest form if the only common factor of the numerator and denominator is 1 or -1.
is f (x) = 6x + 2 a linear function or not? WHAT IS THE M AND B
A linear function has an equation of y = mx+b where m = slope and b = y-intercept. The function also has a line graph. By a line graph, the graph must have slope. That means the slope must not equal to 0 or undefined to be a linear function.
Further Explanation
A linear function has both domain and range as set of all real numbers because you are able to solve for x-term when inputting any y-value or solve for y-term when inputting any x-value. We can also find the x-intercept by substituting the value of y to 0 and basically solve for x-term. If we want to know the y-intercept, we can substitute x-term to 0 and solve for y. But most people would only look at b-term from y = mx+b because b-term is the y-intercept of function.
AnswerFrom your question, the function is indeed a linear function. The m-term and b-term both are from y = mx+b where m = slope and b = y-intercept.
Therefore, from y=6x+2. The m-value would be 6 and b-value would be 2
Aniya went bowling and spent $5 to rent bowling shoes and paid $6.75 per game bowled. If Aniya spent $25.25 total, answer the following questions
A Write an equation
B Solve the equation
C Find the cost for 10 games
Answer:
Aniya only needs to pay for her shoes once so $5 is your B or y-intercept. $6.75 is your slope. So your equation in y-intercept form will be y = $6.75x + $5. Now plug in the numbers to find how many games she played if she spent $25.25.
Equation: y = $6.75x + $5
Answer for B:
($25.25 - $5) / $6.75
The answer: She played three games.
Answer for C:
y = $6.75 * 10 + $5
The answer: She paid $72.5 if she bought 10 games and rented a pair of shoes.

Answer:
Complementary Angles: The angle with 32˚ and 48˚
Supplementary Angles: The angle that is together with the angles of 107˚ and 73˚
Neither: The angle with 101˚ and 77˚ since
Step-by-step explanation:
Complementary angles are angles that sum up to 90˚ so 32 plus 48 is 90 which makes it a complementary angle.
Supplementary angles are angles that sum up to 180˚ so 107+73 is 180 which makes it a supplementary angle.
To find the angle with "neither" Complementary nor Supplementary you use the process of elimination
