The equation would be 12(3)+9(1)-50=?
Because if she makes 12 skirt that take 3 yards each, you multiply that to know how many yards the skirts take. Then you multiply 9 by 1 to find the yards that the hats use. Then you subtract the those from the total to get what is left over.

12(3)+9(1)-50=?
36+9-50=?
45-50=?
The answer is 5 yards left over

A pear costs x cents. An orange costs y cents less
VARVARA [1.3K]

Step-by-step explanation:

Pear cost=x

Orange cost=x-y

4 pears= 4x

6 oranges=6x-6y or x-y x6

Use ratio.

Pears: x cents

4 Pears: 6x cents

You x4 on each side. Same with oranges.

Orange: x-y

6 oranges: x-y x6

You x6 on each side.

What is greater 8 yd or 288 in
natali 33 [55]
To solve this problem we need to know the equivalence between yards and inches, that is:
1 yd = 36 inches

Therefore in 8 yd we have:
8(36) = 288
so in 8 yd we have 288 inches
So 8 yd is equal to 288 in

A county has a goal to build 12,000 bus stop shelters in 48 months . If the county builds 215 bus shelters each month , will it
Leokris [45]

Answer:

No, it will not reach its goal.

Step-by-step explanation:

The main reason why it will not meet its goal is because if you do the math, 215 x 48 does not equal 12000, it equals 10320 which is just 1680 shelters low. Therefore, they will not meet their goal.

Calculate the sum of the multiples of 4 from 0 to 1000
allochka39001 [22]

Answer:

sum is 125,500

sum in summation notation is \sum\limits_{n=0}^n a+nd= (2a+(n-1)d)n/2

Step-by-step explanation:

This problem can be solved using concept of arithmetic progression.

The sum of n term terms in arithmetic progression is given by

sum = (2a+(n-1)d)n/2

where

a is the first term

d is the common difference of arithmetic progression

_____________________________________________________

in the problem

series is multiple of 4 starting from 4 ending at 1000

so series will look like

series: 0,4,8,12,16..................1000

a is first term so

here a is 0

lets find d the common difference

common difference is given by nth term - (n-1)th term

lets take nth term as 8

so (n-1)th term = 4

Thus,

d = 8-4 = 4

d  can also be seen 4 intuitively as series is multiple of four.

_____________________________________________

let calculate value of n

we have last term as 1000

Nth term can be described

Nth term = 0+(n-1)d

1000 =   (n-1)4

=> 1000 = 4n -4

=> 1000 + 4= 4n

=> n = 1004/4 = 251

_____________________________________

now we have

n = 1000

a = 0

d = 4

so we can calculate sum of the series by using formula given above

sum = (2a+(n-1)d)n/2

       = (2*0 + (251-1)4)251/2

       = (250*4)251/2

     = 1000*251/2 = 500*251 = 125,500

Thus, sum is 125,500

sum in summation notation is \sum\limits_{n=0}^n a+nd= (2a+(n-1)d)n/2
