(Show work)

Answers

Answer:

v= whl

1200= h X 80

1200/ 80 = h

so the height is 15 unit

Step-by-step explanation:

ANSWER : 15 units

v = h * l * w OR v = h * a

a = l * w

1,200 = h * 80

1200/80 = 15 units

Mr. Jamison will stain the deck in his backyard, the deck has an area of 752.4 sqaure feet. If the deck is 33 feet long how wide is it? Justify your procedure.

Answers

answer:The width of the deck is 22.8 feet.

Step-by-step explanation:

Since we have given that

Area of the deck = 752.4 square feet

Length of deck = 33 feet

Let width of deck be 'x'.

Since Deck is in the shape of rectangle.

As we know the formula for "Area of rectangle ":

\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}

Area=Length×width

752.4=33×x

752.4

22.8=x

Hence, the width of the deck is 22.8 feet.

Evaluate.

A school allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £25 each and are on offer for 1/5 off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip?

Answers

Answer:

40 students

Step-by-step explanation:

If the tickets are 1/5 that means they cost 4/5

25 * 4/5 = 20

The tickets cost 20 and the train costs 15 so the total per person is 35

Teachers: 2 at 35 = 70

1500 -70 = 1430

Take 1430 / 35 =40.85714286

We can send 40 students

Answer:

Step-by-step explanation:

since the school allots £1500 to spend on a trip to the theatre. Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off

therefore 4/5*35 = 28 for the tickets

A train ticket for the day will cost £15 each.

therefore total cost for each: 28 + 15 = 43 pounds each

If 2 teachers and the maximum number of students attend, how much money will the school have left over?

let s = no. of students

43(s+2) =< 1500

43s + 86 =< 1500

43s =< 1500 - 86

43s =< 1414

s =< 1414/43

s =< 32.88, 32 students max

find how much left over. plus 2 teachers = 34 people

1500 - 43(34) =

1500 - 1462 = 38 pounds left over

(11)(n)+(11)(−3)=−4(Distribute)

11n+−33=−4

11n−33=−4

Step 2: Add 33 to both sides.

11n−33+33=−4+33

11n=29

Step 3: Divide both sides by 11.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle

Amy multiplied 2.20 by 75 to find my answer.”

220/100×75=2.2

His answer is correct

Barden

Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%

Braden is correct.

Colton created table for 100%, 10% and 10% percent and added these.

But this addition would result in 100+10+10 =120% not 220%

Hence Colton is wrong.

Danielle divided 75 by 5 to find 20%.

Then he added 75 twice to find his answer.

Danielle is correct.

Hence Colton got the wrong answer
