Answer:
1st Q- B
2nd Q- A
Step-by-step explanation:
1st Q:
n²<220<(n+1)²
n²<220<(n²+2n+1)
we can plug in the values in the answers and see which one satisfies the inequality:
when n=13 --> 13²<220<(13²+2*13+1) => 169<220<196 (this one does not work)
when n=14 --> 14²<220<(14²+2*14+1) => 196<220<225 (this one works)
when n=15 --> 15²<220<(15²+2*15+1) => 225<220<256 (this one does not work)
when n=16 --> 16²<220<(16²+2*16+1) => 256<220<289 (this one does not work)
so the answer is B
2nd Q:
A

What is the product of the solutions to the given equation? Give your answer step-by-step, please.
Answer:
The factors that multiply to equal
x^2 - 13x + 42 = 0
is
(x-6)(x-7) = 0
So,
(x-6) = 0
x = 6
(x-7) = 0
x = 7
6, and 7, are the solutions. They are asking for PRODUCT of the solutions, which means to multiply.
So, 6 times 7 = 42.
The answer is 42

Line GH passes through points (-6,-30) and (4,-5) . What is the linear equation for line GH?
Answer:
y=1/4x+2
Step-by-step explanation:
The point-slope form of the equation of the line that passes through (-4, -3) and (12, 1) is y - 1 =1/4 (x - 12). The slope-intercept form of the equation for this line.
Answer:
y=1/4x+2
The point-slope form of the equation of the line that passes through (-4, -3) and (12, 1) is y - 1=1/4 (x - 12). The slope intercept form of the equation for this line.

2. What is the area of this polygon? Show your work.
Answer:
40 cm^2
Step-by-step explanation:
The area of the polygon is comprised of two triangles, each of which can be broken down into two right triangles for a total of four right triangles when split vertically.
The formula for the area of a triangle is: A = 1/2 * base * height.
The base for both triangles is 8 cm, and the height for both triangles is given on the right (6 cm for the top triangle and 4 cm for the bottom triangle).
The area of the top triangle will be:
A = 1/2 * 8 * 6
A = 4 * 6
A = 24
The area of the bottom triangle will be:
A = 1/2 * 8 * 4
A = 4 * 4
A = 16
Adding the values of the two areas, we get a total area of 40 cm^2.

2 bottles of grape juice fill 8 glasses. How many glasses can be filled from
8 bottles of grape juice?
Answer:
32 glasses
Step-by-step explanation:
To solve this we will first find out how many glasses one bottle of grape juice can fill.
Equation:
8/2 = 4
This means one bottle of grape juice can fill four glasses. Now all we have to do is multiply 4 glasses of grape juice by the number of bottles.
Equation:
8 * 4 = 32

175 = x
) A day’s sale at a book shop is represented in a pie chart with the following data. If the total sale at the end of the day is ₹ 1440, then how much was the contribution of Non Fiction books towards the sale? *
Rs 360
Rs. 230
Rs. 320
Non fiction has 80 degrees
Answer:
Rs. 320
Step-by-step explanation:
Contribution of Non Fiction books towards the sale = (degree of non fiction books / total degrees in a circle ) x 100
degree of non fiction books = 80
total degrees in a circle = 360
(80 / 360) x 1440 = Rs. 320

What is the initial value of the function represented by this graph?
A coordinate grid is shown with x- and y-axes labeled from 0 to 7 at increments of 1. A straight line joins the ordered pair 0, 7 with the ordered pair 4, 0.
A. 0
B. 3
C. 4
D. 7
Answer:
D
Step-by-step explanation:
The initial value is the beginning output value, or the y-value when x = 0. Therefore, since y is at 7 when x is at 0, the answer is 7.
In a city, polio drops were given to 2,12,583 children on Sunday in March 2008 and to 2,16,813 children in the next month .Find the difference of the number of children getting polio drops in the two months
Answer:
4,28,766 childrens
Step-by-step explanation:
The computation of the difference in the number of children getting polio drops in the two months is shown below:
The number of children got polio drops in 1st month is 2,12,583
And, the number of children got polio drops in 2nd month is 2,16,813
So, the total children got polio drops is
= 2,12,583 + 2,16,813
= 4,28,766 childrens

A rectangle has sides with lengths (x+5) and (x+6) . Find the perimeter
Answer:
P = 4x + 22
Step-by-step explanation:
Formula
Perimeter = 2*L + 2*W
Givens
L = x + 6
W = x + 5
Solution
Perimeter = 2*(x + 6) + 2*(x + 5) Remove the brackets on both terms
Perimeter = 2x + 12 + 2x + 10 Collect like terms
Perimeter = 4x + 22 Answer
If p=1 and q=4, evaluate the following expression:4q−p/p+q
Answer:
19
Step-by-step explanation:
This was done the normal way of multiplying and dividing first:
If p=1 and q=4, evaluate the following expression:
4q − p/p + q = ?
4(4) - 1/1 + 4 = 16 - 1 + 4 = 19
If you wanted to do the addition and subtraction first, the equation would have been:
(4q - p)/(p + q) = ?
(4(4) - 1)/(1 + 4) = 15/5 = 3
With the parentheses, the order of operations is done in the parentheses first.
