The sum of the first 1 million primes is N. Without knowing N's value, one can determine that the ones'digit of N cannot be

1 answer:

3 0

All primes are odd, except two. Therefore the sum of the first million primes is one even number plus 999999 odd numbers. Since odd*odd = odd, the first million primes must be even + odd = odd.

An odd number obviously has an odd final digit, so the only option that can be firmly rules out is b (which is even).

A graph represents the perimeter ,y, in units for an equilateral triangle with the side lengths x units. The slope of the line i

kicyunya [14]

Answer:

see the explanation

The graph in the attached figure

Step-by-step explanation:

The correct question is

Explain what the slope and intercept mean in each situation.

A graph represents the perimeter,y, in units, for an equilateral triangle with side length x units. The slope of the line is 3 and the y-intercept is 0

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem

y is the perimeter in units

x is the side length of a equilateral triangle

we have

$m=3\\b=0$

substitute

The linear equation is

$y=3x$ ---> Is a proportional relationship because the line passes through the origin

see the attached figure to better understand the problem

Explanation

The slope is ---> $m=\frac{3}{1}\frac{units}{unit}$

That means

The ratio of perimeter of triangle to side length of triangle is 3:1

The y-intercept is 0

Remember that

The y-intercept is the value of y when the value of x is equal to zero

In this context

The y-intercept is the value of the perimeter when the value of the side length is equal to zero

The value of the perimeter is 0 when the value of side length is 0

A builder was building a fence. In the morning, he worked for 2/5 of an hour. In the afternoon, he worked for 9/10 of an hour. H

Bas_tet [7]

Hey there! I'm happy to help!

We want to see how many times bigger 2/5 is than 9/10. Let's call how much bigger 2/5 is b and solve below.

9/10b=2/5 (2/5 is b times larger than 9/10)

We divide both sides by 9/10, so your division would be 2/5÷9/10.

b=4/9

Therefore, the builder worked 4/9 times as long in the morning as he did in the afternoon.

Have a wonderful day! :D

You want to paint a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. There

Nataly_w [17]

Answer:
3 hours

Explanation:
1) Set an expression for each of the studios we can set out variable as h for hours because that is the unknown value.

Studio A: 10+8h
Studio B: 16+6h

To find out how many hours would pass for their costs to equal each other, we have to make them literally equal each other.

10+8h=16+6h

Now that we have an equation, we can start solving.

10+8h=16+6h
Combine like terms
10-16=6h-8h
-6=-2h
2h=6
Divide both sides by 2 to isolate h
2h/2=6/2
h=3

I hope this helped! If it did, a brainliest would be much appreciated :)
