Answer:

error in step one

Step-by-step explanation:

Sunny earns $22.75 per week delivering. delivery boy for 3 weeks.

That means $22.75 x 3 not $22.75 + 3

He can correct his mistake by doing this:

<em>Step 1: [($22.75 * 3) + $32.75 - $14.25] * 1/ 5 </em>

<em> </em>

<em>Step 2: [$86.75] *1/5 </em>

<em> </em>

<em>Step 3: $17.35</em>

<em />

<em> </em>

Simplify the expression: show all ur steps/ wrk PLEASE,1+2x3-18/3+(5(2+2)]
Maurinko [17]
Ok let's do this*pops knuckles*



let's add the first side

1 + 2 \times 3 - 18
order of operations demands that we do multiplication first(P.E.M.D.A.S)

so
2 \times 3 = 6
now we can add the 1 from
1 + (6) - 18
into our six


6 + 1 = 7
now we substract

(7) - 18 =  - 11
now we have
- 11  \div 3 + (5(2 + 2))
now we focus on the
other side
3 + (5(2 + 2))
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
(5(2 + 2)) = (((5 \times 2) + (5 \times 2) = 20
now we have
3  + 20 = 23

(the three is from the original equation)

now we plug in our final numbers

- 11 \div 23
or
\frac{ - 11}{23}
I hope this helps

I need help finding both volume and surface area
Svetradugi [14.3K]

Answer:

<u>Volume</u>

For the rectangle, h = 3cm, l = 8cm, w = 6cm
V = length x width x height
V = 8cm x 6cm x 3cm
V = 144cm^3

For the semi circle, we need to find the radius. The radius is width/2, so 6cm/2 = 3cm. r = 3cm, \pi = 3.14
V = radius^2 x height x \pi
V = 3cm^2 x 3cm x 3.14
V = 84.8 cm^3/2 (because the cylinder needs to be divided to form a semi-circle)
V= 42.4cm^3 (there are two cylinders though so we will multiply this by 2 in the total volume)

Total volume:
V = 144cm^3 + 42.4cm^3(2)
V = 186.4cm^3

<u>Surface Area</u>

Rectangular prism:
A = 2[w(l) + h(l) + h(w)]
A = 2[6cm(8cm) + 3cm(8cm) + 3cm(6cm)]
A = 180cm^2
But there are two sides that are covered by the semi-circular prisms, so we will have to calculate those sides and remove them.
A = l x w
A = 6cm x 3cm
A = 18cm^2(2) (2 being the two faces)
A = 36cm^2

A = 180cm^2 - 36cm^2
A = 144cm^2 (the area of the rectangle)

Semi-circular prism:
A = 2\pirh + 2\pir^2
Earlier, we found out that the radius of the circle is 3cm, so we will plug that in.
A = 2(3.14)(3cm)(3cm) + 2(3.14)(3cm)^2
A = 113.09cm^2

Total surface area:
A = 144cm^2 + 133.09cm^2
A = 277.09cm^2

Therefore the total volume of the prism is 186.4cm^3 and the total surface area is 277.09cm^2.

Answer:

see in the picture, the perimeter of this rectangle is

2( x + 3x) = 8x but the perimeter is 65.6

=> 8x = 65.6

<=> x = 65.6/8

=> x = 8.2
