Answer:
the answer is D
Step-by-step explanation:
sorry if I did it wrong
Answer:
D. Yes because the sum of two lengths of any two sides...etc.
This is your answer
Step-by-step explanation:
side1 m = 3
side2 m = 7
2 smaller sides = ( 3 + 7) = 10
10 is larger than 8
proof Pythagoras theorem
3^2 + 7^2 = c^2
sqrt 9 + sqrt 49 = c^2
c^2 = sqrt 58 = 7.6 = 8 rounded to 1 significant figure.
Proof 2
show ratios of each side 3 : 7 : 9
The circumradius of a cyclic polygon is a radius of the circle inside which the polygon can be inscribed. The height can sometimes be such radius but this should be proved from the equation height of a triangle equation
isosceles not using Pythagoras = hᵇ = √ (a² - (0.5
isosceles using Pythagoras= h = 2 * area / b
obtuse height formula =Area of an obtuse-angled triangle = 1/2 × base × height. Therefore, the height of the obtuse triangle can be calculated by: Height = (2 × Area)/base Substituting the values, we get:.
So as we know Given a=3 and c=8, shows a higher amount for 7 but stays 7 in all circumstances of 1significant figure just like 8 stayed rounded down when using round figure just 7. We get;
b = 7.4162
∠α = 22.024° = 22°1'28" = 0.3844 rad
∠β = 67.976° = 67°58'32" = 1.1864 rad
h = 2.78107
area = 11.1243
perimeter = 18.4162
inradius = 1.2081
circumradius = 4
When the circumradius is 4 and we need the ratio to the inradius
this means the ratio is R : r as;
3/4 :7/4 : 8/4 = 18/4 / 7/2 = 9/7 which shows us the cr radius to the in radius ratio.
R:r therefore = 9/7

Nina works in as an office receptionist for $15.00 per hour. If her pay is increased to $18.00, then what is her percent increase in pay?
*If you solve this for me can you also put how you got to the answer? just so I can see how you did it :]
Answers
Answer:
20%
Step-by-step explanation:
the number is increased by 3 so you put 3 on 15 and 3/15=1/5=2/10=20/100
The percentage increase in the pay of Nina is 20%.
How to calculate percentage increase?To calculate the percentage increase work out the difference (reduction) between the two figures you are comparing before calculating a percentage drop. Then, increase the result by 100 after dividing the decrease by the initial number.
% Increase = Increase / Original Number × 100
Nina got the initial pay as $15.00 per hour.
After the increment, her pay increased to $18.00.
The total increment = final pay - initial pay
= 18.00 - 15.00
= 3.00
Now, the percentage increase = (3/15)×100
= 20
Therefore, there is the 20% increment for the pay of Nina.

Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answers
Answer:
The slope of AB is undefined; the slope of CD is 0; The lines are perpendicular.
Step-by-step explanation:
Line AB would form a vertical line. Slope is Δy/Δx. To go from 3 to 7 (the y-coordinates) you need to go up 4 units. So we would then have Δy/Δx = 4/Δx. To go from -5 to -5 (the x-coordinates) we have to go left or right 0 units. So, Δy/Δx = 4/Δx = 4/0. Anything divided by 0 is undefined. Remember: vertical lines always have an undefined slope.
Line CD would form a horizontal line. To go from 9 to 9 (the y-coordinates) you need to go up or down 0 units. So, Δy/Δx = 0/Δx. To go from 1 to -10 (the x-coordinates) you need to go down 11 units. So Δy/Δx = 0/Δx = 0/1. 0 divided by anything is 0. Remember: horizontal lines always have a slope of 0.
If you picture a horizontal line and a vertical line intersecting, they would both form a right angle when they intersect. By definition, this would make both lines perpendicular.

The sum of four consecutive integers is 134. Find the integers. (please show your work)
Answers
Answer:
Integers: 32,33,34,35
Step-by-step explanation:
Consecutive means back-to-back, with a difference of 1
Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum
[tex]x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32[/tex]
Therefore since x = 32, all four integers are:
[tex]32,33,34,35[/tex]
If we check this, we can see that their sum equals to 134
[tex]32+33+34+35 = 134[/tex]

A new club sent out 288 coupons to boost sales for next year's memberships. They provided 5 times as many to potential members than to existing members. How many coupons did they send to existing members?
A.
6
B.
5
C.
53
D.
48
Answers
Answer:
D. 48
Step-by-step explanation:
We don't know the numbers of coupons sent to existing members and to potential members, but we know a relationship between the number.
They sent 5 times as many coupons to potential members as they did to existing members.
Let x = number of coupons sent to existing members.
Then 5x = number of coupons sent to potential members.
The total number of coupons sent was x + 5x = 6x
The total number of coupons sent was 288.
Therefore, 6x must equal 288 giving us an equation with a single variable.
6x = 288
x = 48

x² -6x+2=0
a=1 a>0 so it has minimum value/point
since it is quadratic equation, hence the extreme value is at minimum point which is (3,-7)
in order to get that differentiate x²-6x+2
2x-6=0
2x=6
x=3
subtitude x=3 into the original equation
(3)²-6(3)+2
9-18+2
-7
extreme point (3,-7)
in order to know whether it is the solution of the equation or try subtitude it into the equation
(-3+√7)² -6(-3+√7)+2≠0
36-12√7≠0
(-3-√7)² -6(-3-√7)+2≠0
36+12√7≠0
(3+√7)² -6(3+√7)+2=0
(3-√7)² -6(3-√7)+2=0

a^2 + b^2 = c^2
a = one of the sides, not hypotenuse
b = the other side, not hypotenuse
c = the hypotenuse (longest side)
9) We need to rearrange the equation, as x is looking for a side other than the hypotenuse. The rearranged formula would be:
a = √(c^2 - b^2)
One of the sides, b, is given as 22. The hypotenuse, c, is given as 37. Plug these numbers into the formula and solve.
a = √(37^2 - 22^2)
a = √(1368 - 484)
a = √884
a = 29.73
x = 29.73
10) Use the same rearranged formula, solving the same way
11) Use the original (not rearranged formula) and solve for the hypotenuse

Answer:
It's A. Edge 2022
Step-by-step explanation:
So basically, you just multiply 10, 20, 30, and 40 by 0.75
So now the numbers on your table are 7.5, 15, 22.5, and 30.
7.5 + 7.5 is 15, 15 + 7.5 is 22.5, and 22.5 + 7.5 is 30, so it's linear.
7=3 over 4x what is x?
Answers
Answer:
x=28/3
Step-by-step explanation:
combine multiplied terms into a single fraction
7 = 3x/4
multiply all terms by the same value to eliminate fraction denominators
4 · 7 = 4 · 3x/4
cancel multiplied terms that are in the denominator
4 · 7 = 3x
multiply the numbers
28 = 3x
divide both sides of the equation by the same term
28/3 = 3x/3
simplify
a. cancel that are in numerator and denominator
28/3 = x
b. move the variable to the left
x = 28/3
