Round to the nearest cent. 5. $406.439

1 answer:

boyakko [2]3 years ago

7 0

Answer:

406.4

Step-by-step explanation:

When rounding you only look at the number you're rounding and the one before it. In this case it would be the 4 and 3 after the decimal since we're rounding to the nearest cent. If the numbers before the one you're rounding are 0-4 then you leave the number the same. If the numbers are between 5-9 then you add one to the number. Since the number before 4 is between 0-4 you leave it as 4. But if it was between 5-9 then you'd change the 4 to 5.

An artist used silver wire to make a square that has a perimeter of 40 inches. She then used copper wire to make the largest cir

Serhud [2]

Answer:

The artist used $8.6\ in$ more of silver wire

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

we know that

The Perimeter of the square is equal to

$P=4a$

where

a is the length side of the square

$P=40\ in$

so

$40=4a$

$a=10\ in$

so

Each side of the square has a length of 10 in

step 2

Find the circumference of the circle

The diameter of the circle is equal to the length of the side of the square

The circumference is equal to

$C=\pi D$

we have

$D=10\ in$

substitute

$C=(3.14)(10)=31.4\ in$

step 3

Find the difference

$40\ in-31.4\ in=8.6\ in$

Solve for x. <br> 3x+7 = -x-1

alekssr [168]

Answer: x = -2

Step-by-step explanation: 3x+7 = -x-1; add 1 to both sides: 3x+8=-x; subtract 3x from both sides: 8 = -4x; divide by -4 on both sides: -2 = x

Help for number 10 please

tamaranim1 [39]

Start with

$4(3^3-8) \div 2$

Exponents have the highest priority, so we evaluate 3 cubed first:

$4(27-8) \div 2$

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

$4 \times 19 \div 2$

Multiplications and divisions have the same priority, so we perform them as they appear: $4 \times 19 = 76$ , so the expression becomes

$76 \div 2 = 38$
