Four consecutive multiples of 5 add up to 4130 what is the largest number?

To find multiples of a number we multiply that number with natural numbers, 1, 2, 3, 4, ... . Since those natural numbers are also called the consecutive positive integers, let's denote with x the first of the four consecutive positive integers whose product with 5 add up to 4,130. So we are adding these multiples of 5: 5x + 5(x + 1) + 5(x + 2) + 5 (x + 3) = 4,130 5x + 5x + 5 + 5x + 10 + 5x + 15 = 4,130 20x + 30 = 4,130 20x = 4,100 x = 205 Since we are interested for the largest multiple, then we have: x + 3 = 205 + 3 = 208 5 x 208 = 1,040. Thus, the largest number is 1,040.


The smallest angle in a triangle is one-half the size of the largest The middle angle measures 25degrees less than the largest Find the measures of the three angles?

Sum of all the angles in the triangle has to be 180 degrees. Let's mark the largest angle as x. Then, smallest angle will be 0.5x and the middle one x-25. x + 0.5x +x - 25 = 180, which is after simplyfying: 2.5x = 205 x = 82 degrees -> the largest angle, x-25 = 57 degrees -> middle one, 0.5x = 41 degrees -> the smallest angle.

What is the area of a circle with a circumference of 410 meters?

Circumference = 2pi*r 410 = 2pi*r r = 205/pi A = pi*r^2 A = pi*(205/pi)^2 A = 205^2/pi metres A = 42 025/pi metres


What is the circumference of a car tire?

Check the sidewall markings. For example, it might say: "205/55 R16 91H" For circumference, you need the first three numbers. (The last number is the weight rating, the last letter is the speed rating. The "R" means radial, which all modern tires are.)205 is the width in mm55 is the ratio of the sidewall height in percentage of the width. (IOW: 55% of 205 mm)16 is the wheel diameter in inchesFirst convert the tire width to inches:205 / 25.4 = 8.07 inThen get the sidewall height:8.07 * 55% = 4.44 inThe diameter of the tire is the wheel diameter plus two sidewall heights:16 + 4.44 + 4.44 = 24.88 inFinally, circumference is 2 * Pi * radius, or pi * diameter:3.14 * 24.88 = 78.1 inIn one formula, the above would be:( (205/25.4 * 55/100 * 2) + 16) * PI()Also, there are many online calculators that will calculate all this for you.

What is the difference between 195 65 R15 tires and 205 60 R15 tires?

They are pretty close in overall diameter as the 205 will be .3" smaller. Your speedometer will be .7 mph fast with the 205. Your engine will turn an additional 10.1 RPMs every mile driven with the 205. The 205 is a good swap if you want a wider tire.

Can you use 205 55r 16 tires in place of 205 50r 16 tires?

You can but your speedometer will be off. The 205/50-16 has a diameter of 24.1 " and the 205/55-16 has a diameter of 24.9". That is a difference of .8". I suggest you stick with the OEM size. Click the link to see what effect different sizes will have.

What is the difference between p225 70 r16 and p235 75 r16?

Lots of difference. The 235/75 is 1.57" larger in overall diameter. Radius, section width, and circumference is larger. If you wish to go to a 75 series tire then either a 215 or 205 will work well.
