I'm thinking c because 1500 would cover the 1436 pounds of hay that you need and you would multiple by 2 and not divide

Please answer correctly !!!!!!! Will mark brainliest

Sauron [17]

Answer:

option 1

Step-by-step explanation:

y = 3x + 3 ie 3x -y +3 =0 a1= 3 , b1=-1 , c1=3

y = -2x + 3 ie -2x -y+3 = 0 a2=-2 , b2=-1 , c2=3

on comparing the ratios ,

a1/a2 = 3/2

b1/b2 = -1/-1= 1/1 =1/1= 1

a1/a2 ≠ b1/b2

therefore the pair of linear equations will have exactly one solution

Answer:

560

Step-by-step explanation:

Givens

Small mugs = 1/4 * 132 = 33

Large mugs = 132 - 33 = 99

Solution

Profit Small = 33 * £2.45 = £80.85

Profit Large = <u>99 * £4.90 = £485.10</u> Add

Total Profite = £565.95

Approximate the sum of the convergent infinite series the least usingnumber of terms so that the error is less than .0001. What

____ [38]

Solution :

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ $a_n= \frac{(-1)^n}{n ! 2^n} \ \ \ \ \ a_{n+1}= \frac{(-1)^{n+1}}{(n+1) ! 2^{n+1}}$

Error = $|a_{n+1}|$

Error ≤ 0.0001

$|\frac{(-1)^{n+1}}{(n+1)!2^{n+1}}| \leq 0.0001$

$|\frac{1}{(n+1)!2^{n+1}}| \leq 10^{-4}$

$(n+1)! 2^{n+1} \geq 10000$

Now try, n ≥ 5

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = $\sum_{n=1 }^{5 } \frac{(-1)^n}{n ! 2^n}$ (with error 0.0001)

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = $\frac{-1}{1!2}+\frac{1}{2!2^2}-\frac{1}{3! 2^3}+\frac{1}{4! 2^4}-\frac{1}{5! 2^5}$

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = 0.6065104

. In April, it rained 1/4 of an inch on 15 different days. How many inches of rain fell

notka56 [123]

Answer:

3.75, or $\frac{15}{4}$ inches of rain during the 15 days of April.

Step-by-step explanation:

All you have to do is add $\frac{1}{4}$ 15 times to get that number.

$\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ + $\frac{1}{4}$ = 3.75

You can also do 15 times $\frac{1}{4}$ , which will result in the same thing.
