Find the nearest place value. Use #13 to do #14
kondaur [170]
When rounding here are the rules
If the next number to the right is 1-4, you will round down or keep the # the same.
If the next number to the right is 5-9, you will round up to the next number.

So with your # 281,421,906
a. hundred million.  This is the first 2...the number to the right of it is 8, so we will round the 2 up.  And the answer is 300,000,000
b. ten million.  This is the 8...the number to the right of it is 1, so we will round it down and 8 will remain an 8.  And the answer is 280,000,000
c. million.  This is the first 1 (281)...the number to the right is 4, so we will round down and 1 will remain a 1.  And the answer is 281,000,000
d. hundred thousand.  This is the 4...the number to the right of it is 2, so we will round down and the 4 will remain a 4.  And the answer is 281,400,000
e. thousand.  This is the second 1 (281,421)...the number to the right is the 9, so we will round up and the 1 will become a 2.  And the answer is 281,422,000

Now for #14, think about the rules.
  1. If you round it to the nearest one, you get 7.  
  2. If you round it to the nearest tenth, you get 7.0.
  3.  If you round it o the nearest hundredth, you get 7.00
  4.  It is the least number that fits the clues.

Ok basically it is saying, it rounds up to 7.  So what would be the number that would round UP to 7?  That would be 6.  I'm rounding UP because it says it is the LEAST number that fits the clues.

What is the surface area of the rectangular pyramid
posledela

Answer:

<h2>41.74 m²</h2>

Step-by-step explanation:

We have:

rectangle 4.8 m × 3.8 m

two triangles with base b = 4.8 m and height h = 2.6 m

two triangle with base b = 3.8 m and height h = 2.9 m.

The formula of an area of a rectangle l × w:

A = lw

Substitute:

A_1 = (4.8)(3.8) = 18.24\ m^2

The formula of an area of a triangle:

A=\dfrac{bh}{2}

Substitute:

A_2=\dfrac{(4.8)(2.6)}{2}=6.24\ m^2\\\\A_3=\dfrac{(3.8)(2.9)}{2}=5.51\ m^2

The Surface Area:

S.A.=A_1+2A_2+2A_3\\\\S.A.=18.24+2(6.24)+2(5.51)=41.74\ m^2

Simple the expression <br> ( 3k + 4 1/5) + 8 3/5
lesantik [10]

Answer:

3k+12\frac{4}{5}

Step-by-step explanation:

(3k+12\frac{4}{5})

Convert mixed numbers to improper fractions:

a\frac{b}{c}=\frac{a*c+b}{c}

4\frac{1}{5}=\frac{4*5+1}{5}

=\frac{21}{5}

=(3k+\frac{21}{5} )+\frac{43}{5}

Add the fractions

\frac{21}{5}+\frac{43}{5}

\frac{21}{5} \frac{43}{5} =\frac{64}{5}

=3k+\frac{64}{5}

Divide 64 by 5

\frac{64}{5}12.8 or 12\frac{4}{5}

=3k+12\frac{4}{5}
