What is 7,491,001 rounded to the nearest hundrer thousand

Answers

Answer 1

Answer:

Answer:

7,491,001 --> 7,500,000

Step-by-step explanation:

This is because rounding happens like this:

The rounding rule is: 5 and above rounds up, and 4 and under rounds down.

Here is a little rhyme for the rule: 5 and above rounds up like a dove. 4 and below, get down low!

7,491,001

--> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.

I hope I helped!

I need help on this one question please someone help me pleases

Answers

so we simplify this and do
5(3a-1)-2(3a+2)=3(a+2)+v
15a-5-6a-4=3a+6+v
add like terms
9a-9=3a+6+v
subtract 6 from both sides and get
9a-15=3a+v
subtract 3a from both sides and get
6a-15=v or 3(2a-5)
so the answers are D,E

or if you want to avoid doing allot of math, you could just figure out which two answer choices are the same (D,E)

5(3a-1)-2(3a+2)=3(a+2)+v
15a-5-6a-4=3a+6+v
9a-9=3a+6+v
9a-15=3a+v
6a-15=v or 3(2a-5)
so the answers are D,E

Can a right triangle have a leg that is 10 meters long and a hypotenuse that is 10 meters long

Answers

lets see
a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other

no cannot

Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².

Given

α² = 10
c² = 10

Solve

α² + β² = c²
α² (10²) + β² = c² (10²)
100 + β² = 100
β² = 100 - 100 = 0

Simplify

A right triangle can not have a leg that is 10 meters long and a hypotenuse that is 10 meters long.
