1. 23-6 is 17 plus 9 is 26

2. You have to multiply first. 8x2 is 16
32-16/4
16/4 is 4 so you are left with 32-4 which is 28

hopefully that helps so that you can figure out the others without help <3

<h2><u>Direct answer</u> :</h2>

Width of the enlarged photograph = 14 cm

<h2><u>Steps to derive the correct answer</u> :</h2>

Length of a small photograph = 6 cm

Width of a small photograph = 4 cm

Length of the photograph when enlarged = 21 cm

Let the width of the photograph when enlarged be x.

Which means :

= \tt 4 : 6 : : x : 21

=\tt  \frac{4}{6}  =  \frac{x}{21}

=\tt 4 \times 21 = 6 \times x

=\tt 84 = 6x

=\tt x =  \frac{84}{6}

=\tt x = 14

Thus, the value of x = 14

Therefore, the width of the enlarged photograph = <u>14 cm</u>

CAN I GET ANY HELP FOR MY HOMEWORK PROBLEMS? :( Solve the system of equations by using the substitution method. <img src="https:
IRINA_888 [86]

Answer:

One solution. (x,y) = (-5,25)

Step-by-step explanation:

y = -5x

x + y = 20

x + (-5x) = 20

-4x = 20

x = -5

y = -5 (-5)

y = 25

Let tk(x)tk(x): be the taylor polynomial of degree k of the function f(x)=sin(x)f(x)=sin⁡(x) at a=0a=0.suppose you approximate f
Aloiza [94]
<span>Ans : Note that: sin(x) = sum(n=0 to infinity) [(-1)^n * x^(2n + 1)]/(2n + 1)!. Then, since the series is alternating, the error in the approximation found by taking the first n terms of the series is no bigger than the n+1'th term. In other words: E ≤ a_n+1 = x^(2n + 3)/(2n + 3)!. (Note that a_n does not include (-1)^n, the alternating part) We need that 1/6 ≤ x^(2n + 3)/(2n + 3)!. Given |x| < 1, n = 2 will be the least integer solution. Thus, we need 2 + 1 = 3 terms.</span>

URGENT, WILL GIVE BIG BRAIN OR WHATEVER ITS CALLED LOL
KATRIN_1 [288]

Answer: 10,500 hits

Step-by-step explanation:

I WANT BIG BRAIN! I WANT BIG BRAIN AHAHHHHHHH!!!!!!!

ok there are a number of ways to go about this

it is unclear whether or not the YT content creator will get one pound for 500 hits

i honestly dont know but i am going to assume it will

1000 times 20 (we are plugging in a test variable, 20, here)

so lets say we have 20,000 hits

lets divide that by 1000 and we get 20. 20 times 2 is 40 pounds so obviously thats too much

lets try 1000 times 10

so we have 10 times 2 and thats 20 pounds. we are closer

10,500 hits

(i put in 500 because half of 1000 is 500 and that will give you one pound instead of two)

On a certain hot​ summer's day, 189 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for
serious [3.7K]

Answer: x children and (481-x) adults.

1.25x +2.25(481-x) = 865.25

1.25x +1082.25 -2.25x =865.25

x= 217

so 217 children and 481-217 = 264 adults

hope this helped <333
