A triangle has sides with lengths of 9 miles, 12 miles, and 15 miles. Is it a right triangle?
Answer:
The three sides 9 in, 12 in, and 15 in do represent a right triangle. Since the square of the hypotenuse is equal to the sum of the squares of the other two sides, this is a right triangle.
Step-by-step explanation:
15² = 9² + 12²
225 = 81 + 144
225 = 225
so it is an right angled triangle....
( using : if the sum of the squares of the smaller two sides is equal to the square of the largest side, then the traingle is a right triangle.)

For the curve y=x^4+1, find the gradient of the secant between the point (1, 2) and
the point where x=1.01.
Answer:
4.06.
Step-by-step explanation:
Where x = 1.01, y = (1.01)^4 + 1 = 1.0406 + 1
= 2.0406
So the gradient between (1, 2) and (1.01, 2.0406)
= (2.0406 - 1)/(1.01 - 1)
= 4.06.

The price of a loaf of a particular type of bread increased from $3.70 to $5.59 from 2011 to 2021. What was the percent increase in the price of the loaf of bread over those 10 years? Round your answer to the nearest tenth of a percent.
The price of the loaf of bread over the 10 years was_____%(round to the nearest tenth of a percent.)
Answer:
51.1% to the nearest tenth.
Step-by-step explanation:
Increase = 5.59 - 3.70 = $1.89.
% increase = (1.89/3.70) + 100
= 51.08%
find 60% of 40 gallons.
Hey there!
60% of 40
= 60% * 40
= 60/100 * 40
= 60 ÷ 20 / 100 ÷ 20 * 40
= 3/5 * 40
= 3/5 * 40/1
= 3(40) / 5(1)
= 120 / 5
= 120 ÷ 5 / 5 ÷ 5
= 24/1
= 24 ÷ 1
= 24
Therefore, your answer is: 24

A sample of iron has dimensions of 2 cm x 4 cm x 6 cm and a mass of 100g. What is the density of the sample?
What do we know:
the dimensions ⇒ can help us find the volume, area, surface areamassWhat do we want to find ⇒ Density
To solve that,
⇒ must find the relationship between density, mass, and volume
Definition of density: mass per unit volume⇒ Density = mass / volume
Now let's convert some units to make it into a standard answer:
mass = 100g ⇒ 0.1 kg (1000g = 1kg)volume = 2 * 4 * 6 = 48 cubic centimeters = 0.000048 cubic meter(1 cubic meter = 1000000 cubic centimeter)
⇒ Density = 0.1 / 0.000048 = 2,083.33 kilograms per cubic meter

Answer:
14,880: So yes, it will be greater than 12400.
Step-by-step explanation:
Because you can simplify the fraction from 1 1/5 to 6/5, and 6/5 is equal to 1.2, simply multiply 12400 by 1.2, which would get you 14800. In other words, if it was multiplying by a number less than 1.2, then it would be less than 12400.

Ursula is starting a new national network of science fiction book clubs. The establishment and expansion of the network is as follows. The original network began with eight people in each club and four clubs in each of two states. Every month, the number of people in each club increases by two and the number of clubs in each state grows by one. The number of states where the groups exist also increases by one every month. The total number of people in the network of book clubs is represented by the expression below, where x is the number of months since the clubs were established.
Using derivatives, it is found that the correct option is given by:
A. The expression 2x² + 20x + 32 represents the average rate of increase in the total number of clubs in the network across all states.
What is the meaning of the derivative of a function?It is the rate of change of the function over a period of time.
In this problem, the total number of people in the book club after x months is given by:
f(x) = 2x³ + 20x² + 64x + 64
The derivative is given by:
f'(x) = 4x² + 40x + 64 = 2(2x² + 20x² + 32).
It represents the average rate of change across all states, hence option A is correct.

Hi please help me out I’m really struggling with geometry rn and I can’t afford to buy the tutor thing
Alright let's solve this problem step by step:
Question 1: Find the perimeterDefinition of Perimeter: basically all the side lengths added upThe figure is made up triangles
⇒ however, we do not know the slanted line that goes from the tip to
the edge of the base.
⇒ we can use the Pythagorean Theorem to help us
[tex]2^2 + (5.7)^2 = slanted-line^2\\slanted-line = 6.04[/tex]
Perimeter = 6.04 + 6.04 + 6.04 + 6.04 + 6.04 + 4 + 4 + 4 + 4 + 4
= 50.2 inches
Question 2: Find the slant heightDefinition of Slant height: is the distance measured along a lateral face from the base to the tip along the "center" of the face.
*look at image attached to better understand this definition
⇒ Slant height = 5.7inches
Question 3: Find the Lateral AreaDefinition of Lateral Area: area of the non-base faces only
Lateral Area = 5 * (Area of Triangle Faces)
= [tex]5 *(\frac{1}{2} *5.7 * 4) = 5*2*5.7 = 5 * 11.4[/tex]

-5x < 15
Answer:
[tex]\boxed{{x} > -3}[/tex]
Step-by-step explanation:
Given inequality:
[tex]-5x < 15[/tex]To solve this inequality, we need to isolate the variable on one side and the constant on the other. To do this, we can divide both sides by -5.
[tex]\rightarrowtail -5x < 15[/tex]
[tex]\rightarrowtail \dfrac{-5x}{-5} < \dfrac{15}{-5}[/tex]
[tex]\rightarrowtail x < \dfrac{15}{-5}[/tex]
Note: If we are dividing both sides by a negative integer, the sign changes.
[tex]\rightarrowtail {x} > \dfrac{15}{-5}[/tex]
To simplify 15/-5, we can multiply -1 to the numerators and the denominators. As a result, the negative sign should transfer to the numerator, as when two negative integers multiply each other, the result is a positive integer.

A trapezoid has an area of 151.2 square centimeters. One base is 8.8 cm long. The height measures 10.5 cm. What is the length of the other base?
Answer:
x=20
Step-by-step explanation:
(1/2)*10.5*(8.8+x)=151.2
8.8+x=151.2*2/10.5
8.8+x=28.8
x=28.8-8.8
x=20
Answer: 20 cm
Step-by-step explanation:
area of trapeziod = ( (base + base) / 2) x height
151.2 = ( (8.8 + base) / 2 ) x 10.5
14.4 = ( (8.8 + base) / 2)
14.4 x 2 = 8.8 + base
28.8 - 8.8 = base
base = 20 cm
