The town Atlanta needs $14,000 for a new playground Lanzetta Elementary school raise $5358 Lantana middle school race $2834 Atla
Elza [17]
Lanzetta Elem. raised 5358....round to 5,000
Lantana Mid. Sch raised 2834....round to 3,000
Atlanta High Sch. raised 4132...round to 4,000

they need 14,000...they have (5,000 + 3,000 + 4,000) = 12,000....so they will need (14,000 - 12,000) = 2,000 more....keep in mind, these are estimates...not exact answers

For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?
Verdich [7]

Answer:

72 kg

Step-by-step explanation:

For concreatting a tower cement, sand, stones are in the ratio 1:2:4 For 144kg sand.. What amount of cement is required?

We are given the ratio

cement: sand:stones

= 1:2:4

The sum of proportion =

1 + 2 + 4 = 7

We are given the kg of sand = 144kg

Step 1

We find the total kg of cement, sand and stones = x

Using the proportion of sand,

2/7 of x = 144kg

2/7 × x = 144kg

2x/7 = 144kg

Cross Multiply

2x = 7 × 144kg

x = 7 × 144kg/2

x = 504kg

Therefore the total kg of cement, sand and stone = 504kg

Step 2

The amount of cement required is calculated as:

1/7 × 504 kg = 72 kg

Therefore, 72kg of cement is required.

Today only, a desk is being sold at a 33% discount. The sale price is $268. What was the price yesterday?
Serga [27]

Discount percent = 33%

Sale price = $268

Let the original price be $x.

So,

x - (33\% \: of \: x) = 268 \\  =  > x - ( \frac{33}{100}  \times x) = 268 \\  =  > x - ( \frac{33x}{100}) = 268 \\  =  >  \frac{100x}{100}  -  \frac{33x}{100}  = 268 \\  =  >  \frac{(100x - 33x)}{100}  = 268 \\  =  >  \frac{67x}{100}  = 268 \\  =  > 67x = 268 \times 100 \\  =  > 67x = 26800 \\  =  > x =  \frac{26800}{67}  \\  =  > x = 400

So, yesterday the price was $400.
