how many numbers lie between square of 36 and 37
Answer:
73 numbers
Step-by-step explanation:
36²
=36 × 36
=1,296
37²
=37 × 37
=1,369
The total number that lies between 36² and 37² = 37² - 36²
=1,369 - 1,296
= 73 numbers
This is to say that, there are 73 numbers between 36² (1,296 ) and 37² ( 1,369)
If the measure of arc HG = 93°, calculate angle HDG.
Answer:
∠HDG = 87°
Step-by-step explanation:
The angle made by two tangents is the supplement of the intercepted arc.
∠HDG = 180° -HG = 180° -93°
∠HDG = 87°

Which value of p makes the equation 18+ 2 (3p – 8) = –37 true?
O p = -7.83
O p = -6.5
O p = -5
O p = 2.05
Answer:
p = -6.5
Step-by-step explanation:
Given:
18+ 2 (3p – 8) = –37Solving for p:
18+ 2 (3p – 8) = –3718 + 6p - 16 = -376p + 2 = -376p = -37 - 26p = -39p = -39/6p = -6.5Option 2 is correct in the list

Ariel completes the square for the function y=x^2-16x+17. What is the function of the parabola?
Answer:
y = (x - 8)² - 47
Step-by-step explanation:
x² - 16x + 17 = 0
x² - 16x = -17
(-16) / 2 = -8
-8² = 64
x² - 16x + 64 = -17 + 64
(x - 8)² = 47
y = (x - 8)² - 47
If the data in a scatter plot form a nearly perfect circle, the Pearson correlation would be approximately ____.
Answer:
zero
Step-by-step explanation:
Pearson correlation coefficient represented by r is calculated by dividing the covariance by the standard deviation of one variable(x) multiply by the standard deviation of the other variable(y).
A scatter plot diagram is a graphical display of data that in which these two variables are observed simultaneously.
A positive correlation is said to have a positive slope which means that the two variable x and y increases in x as there is increase in y.
On the other hand , when there is an increase in x and a decrease in y, the correlation between x and y is said to be negative and the corresponding regression line has a negative slope.
Occasionally, there may be no apparent association between x and y. In that wise, the data in the scatter plot diagram usually form a nearly perfect circle and are said to have a zero correlation.

A cell phone plan costs $20 a month and includes 200 free minutes. Each additional minute costs 5 cents. Assume that you use your cell phone for at least 200 minutes a month. If x is the total number of minutes a month, then your total cost C is given by:
Answer:
The total cost C = $10 + $0.05·x
Step-by-step explanation:
The given parameters are
The cost of the cell phone plan per month = $20
The number of minutes of free calls that one can make in a month = 200 minutes
The cost of additional minutes of cell phone call = 5 cent
5 cents to a dollar = $0.05
The total number of minutes of calls made in a month = x
The time duration of a person's usage of the cell phone in a month > 200 minutes
The total cost C of a person's usage per month is given by;
C = $20 + $0.05 × (x - 200) = $20 + 0.05·x - $10
C = $10 + $0.05·x
Where x > 200.
Answer:
The total cost C = $10 + $0.05·x

Factor ^2 - 4x + 4.
x^2 - 4x +4=
This is the same as [tex](x-2)^2[/tex]
============================================
Explanation:
The middle coefficient is -4 and the last term is 4.
We need to find factors of the last term that add to the middle coefficient.
Here is a list of all ways to multiply two integers to get 4, and the sum of each pair of factors.
-1 + (-4) = -5-2 + (-2) = -42 + 2 = 41 + 4 = 5The second row of that list above is what we're after. So
-2 + (-2) = -4
-2 * (-2) = 4
Meaning the factorization is (x-2)(x-2). Note the "-2" values in each factor
We can use the FOIL rule or distribution to go from (x-2)(x-2) back to x^2-4x+4 to confirm the answer.
An amount of #550,000.00 was realised when a principal,x was saved 2% simple interest for 5 years. Find the value of x
Answer:
x = 250,000
Step-by-step explanation:
A = P(1 + rt)
550,000 = x (1 +2% x 60)
550,000/(1 +2% x 60) = 250,000
x = 250,000

two angle in a triangle message 2x+30 degree and 5x+30 degree respectively if these angle are congruent, what is the value in degree of X
Answer:
x = 0
Step-by-step explanation:
two congruent angles 2x + 30 and 5x + 30
2x + 30 = 5x + 30
2x = 5x
2x + (-5x) = 5x + (-5x)
-3x = 0
x = 0 / -3
x = 0
The value of x will be;

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Two angle in a triangle 2x+30 degree and 5x+30 degree are congruent.
Now,
Since, Two angle in a triangle 2x+30 degree and 5x+30 degree are congruent.
Hence, We get;
⇒ 2x + 30 = 5x + 30
Solve for x as;
⇒ 30 - 30 = 5x - 2x
⇒ 0 = 3x
⇒ x = 0

From the figure we observe :
Length of laundry room (G) = C - H
G = (4x - 2) - (x + 6) = 3x - 8
Breadth of laundry room (F) = K - E
F = (2x - 5) - (x - 13) = x + 8
(A) Perimeter = 2(L + B)

Triangle QRS is a right triangle with the right angle at vertex R. The sum of m∠Q and m∠S must be equal to 45°. greater than 45° and less than 90°. equal to 90°. greater than 90° and less than 180°.
Answer:
The sum of m∠Q and m∠S must be equal 90°Step-by-step explanation:
The measure of right angle is 90°
The sum of measures of angles in any triangle is 180°
so:
m∠Q + m∠S + ∠R = 180°
m∠Q + m∠S + 90° = 180°
m∠Q + m∠S = 180° - 90°
m∠Q + m∠S = 90°
In right triangle QRS with ∠R = 90° , the sum of m ∠Q and m ∠S must be equal to 90°.
What is right triangle?"Right triangle is defined as the two dimensional figure with three sides and three vertices and angles enclosed in it, with one of the interior angle is of 90°."
Condition used
In ΔQRS
∠Q + ∠R + ∠S = 180°
According to the question,
Given,
In right triangle ΔQRS,
∠R = 90°
Substitute the value in the above condition of triangle we get,
∠Q + 90° + ∠S =180°
⇒ ∠Q + ∠S =180°- 90°
⇒∠Q + ∠S = 90°
Hence, in right triangle QRS with ∠R = 90° , the sum of m ∠Q and m ∠S must be equal to 90°.

how to do this question plz answer me step by step plzz plz plz
Answer:
no
Step-by-step explanation:
The circumference of a table is ...
C = πd = π(180 cm) ≈ 565.5 cm
At 70 cm/guest, a table will accommodate ...
565.5 cm/(70 cm/guest) = 8.08 guests
At 8 guests per table, the available 18 tables will accommodate ...
(18 tables)(8 guests/table) = 144 guests
There is not enough space at 18 tables for 145 guests.
Answer:
No, it's not.
Step-by-step explanation:
First, find the circumference of the table:
C = 2πr
= 2 × 22/7 × 180/2
NOTE: Diameter/2 is equal to the radius because half of Diameter is a radius.
= 44/7 × 90
= 3,969/7
= 565.71 approximately 566cm²
Next, find how many guests can occupy a table:
566/70 = 8.08 approximately 8 guests.
Now, how many guests will be in 18 tables?
18 × 8 = 144 guests, but we need 145 guests, so it is not enough.
