Answer:
8x<80
Step-by-step explanation:
The teams are teams of 8, so 8x is how many people on a team (8) times total number of teams (x). You want it to be less than 80, because, as it said, fewer than 80 people signed up.

Tell whether the given side lengths form a right triangle.
6, 11, 16
Given:
The lengths of the sides of a triangle are 6, 11, 16.
To find:
Whether the given triangles is a right angle triangle or not.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
A triangle is a right angle triangle if the sum of squares of two smaller sides is equal to the square of the largest sides.
In the given triangle the length of the largest side is 16.
Square of the largest sides is:
[tex]16^2=256[/tex]
Sum of the squares of the two smaller sides is:
[tex]6^2+11^2=36+121[/tex]
[tex]6^2+11^2=157[/tex]
Since [tex]6^2+11^2\neq 16^2[/tex], therefore the given triangle is not a right angle triangle.
how do I find the area of this shape. Please help I need to turn this in today
Answer:
A = 70 units²
Step-by-step explanation:
Since all 4 sides are congruent then figure is a rhombus
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then
A = [tex]\frac{1}{2}[/tex] × 14 × 10 = 7 × 10 = 70 units²
Am I correct? Please explain!

Step-by-step explanation:
Solve for x and show your work! For each equation choose if there are:
• zero solutions for x • exactly one solution for x • or an infinite number of solutions for x.
3x + 5 = 7 + 3x
2(3x + 9) = 18 + 6x
Bounty paper towels cost $8.49 for 8 rolls. Brawny paper towels cost $13.99 for 12 rolls. Which is the better buy?
Answer:
Bounty Paper Towels is the better deal
Step-by-step explanation:
8.49 divided by 8 = 1.06125 ($1.01)
13.99 divided by 12 = ~1.16583 ($1.16)
The Brawny is more expensive per roll, so Bounty would be a better deal

Step-by-step explanation:
Mr. Wedmore works at a car dealership and earns
a monthly salary of $2,000. He also earns 25%
commission on the gross profit of the car sales. If
Mr. Wedmore brought in $10,000 worth of profit
for the dealership, how much would he earn this
month?
Answer: $2,000. + 25% + $10,000= 12,500 Or $2,000. - 25% - $10,000=8500
Step-by-step explanation:
Answer: $4,500
Step-by-step explanation: First, the monthly salary is $2,000 so this is part of the total already. The 25% commission is on the profit they earn and the profit they earned was $10,000. To find 25% of $10,000, you do 10,000 times 0.25 which is $2,500.
Total Earned: $2,000 (Monthly Salary) + $2,500 (Commission Amount) = $4,500

Somebody please help me plsssss
Given:
The radius of the cylinder = 2 cm
Height of the cylinder = 5 cm
To find:
The volume of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2,h=5[/tex] in the above formula, we get
[tex]V=\pi (2)^2(5)[/tex]
[tex]V=\pi (4)(5)[/tex]
[tex]V=20\pi [/tex]
Therefore, the volume of the cylinder is [tex]20\pi [/tex] cubic cm and its approximate value is 62.832 cubic cm.
Calculate the circumference of a circle whose radius is 7.2 Cm (Idek I just woke up lol)
Which expression is a factor of 9x^2-4x+1 ( ps ^2 is an exponent)
Answer:
The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Step-by-step explanation:
9x² - 4x + 1 = 0 ax² + bx + c = 0
The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20
b2−4ac < 0, the equation has no real number solutions, it has complex solutions

10th term of 4, 7, 10, 13........ (Please enter number only)
Hint
Use a+(n-1)d
Answer:
31
Step-by-step explanation:
a + (n-1)d where a = first term; n = which number we want; d = common difference.
=> 4 + (10 - 1)3
=> 4 + (9)*3
=> 4 + 27
=> 31

I forgot how to do math
Answer: hope this helps
Step-by-step explanation:
5 (x + 8)
Root:
x = -8
Derivative:
d/dx(2 x + 46 + 3 x - 6) = 5
Indefinite integral:
integral(40 + 5 x) dx = (5 x^2)/2 + 40 x + constant
Answer:
5x-40=0
5x=40
x=40/5
x=8
help me please can someone please help i beg you. i have to say why this is wrong and solve this correctly. i beg you please
Answer:
The person solving the problem first subtracted 6 from 15. Since the cube root is next to the six, the problem should be read as [tex]15-6(\sqrt[3]{\frac{-1000}{27} } )[/tex] rather than [tex](15-6)(\sqrt[3]{\frac{-1000}{27} } )[/tex].
To solve it correctly, first find the cube root of -1000/27: -10/3Next, multiply by 6: -20Finally, subtract from 15: 35please lmk if anything is wrong with my answer, hope this helps :)
Grade 9 -10 help pleaseeee determine length of arc CAD
Answer: Divide the chord length by double the radius.
Find the inverse sine of the result.
Double the result of the inverse sine to get the central angle in radians.
Once you have the central angle in radians, multiply it by the radius to get the arc length.
Step-by-step explanation:
the square of a negative number increased by 6 times the number is 72. Find the number.
Answer:
y = 6
Step-by-step explanation:
(y + 6) × y = 72
y = negative number²
When negative numbers are squared they become positive.
y = 6
Check
(6 + 6) × 6 = 72
12 × 6 = 72
Ashleys Shoe Store buys shoes for $35 and then sells them for
$85.
What is the percent of increase on the price of the shoes?
Round to the nearest whole number
Step-by-step explanation:
% Increase = ((New value - Old Value) / Old Value) * 100
Given New value = $85
and Old Value = $35
% Increase =
[tex] (\frac{85 - 35}{35} ) \times 100 \\ = ( \frac{50}{35} ) \times 100 \\ = 143percent(nearest \: whole \: number)[/tex]

Answer:
cos 25° = X/11
and
sin 65° = X/11
is this good enough or do you need more workings?
Answer:
C = 90°
Step-by-step explanation:
The interior angles in every triangle are equal to 180 degrees. So, this means that
[tex] \alpha + \beta + \gamma \\ = 180 \: degrees[/tex]
Which means that A + B +C = 180 degrees
A=25°
B = 65°
C =?
C = 180° - (A + B)
C = 180° - (25° +65°)
C = 180° - 90°
C = 90°

Mr. Martin had 7 eggs. He used half (½) of these eggs plus one-half (½) another egg to make an omelet. He then used half (½) of what was left plus half (½) another egg to make a batch of cookies. Finally, he used half (½) of what was left plus one-half (½) an egg to make a meatloaf.
Answer:
Number of eggs used to make meat loaf = 1
Step-by-step explanation:
The total number of eggs used to make omelet =
[tex]\frac{7}{2} + \frac{1}{2}\\\frac{8}{2} \\4[/tex]
The total number of eggs used for making cookies
[tex]\frac{3}{2} + \frac{1}{2} \\\frac{4}{2}\\2[/tex]
He is now left with 7 -4-2 = 1 egg only
So he uses this one egg to make meat loaf
