Answer:
Number of bagels = 10
Number of donuts = 25
Step-by-step explanation:
Let Number of bagels = b
Number of donuts = d
As given,
Each donut cost $0.55 and each bagel cost $1.20
⇒ Cost of d donuts = $0.55d
Cost of b bagels = $1.20b
Also given,
Jamian bought a total of 35 bagels and donuts
⇒ b + d = 35 ........(1)
Also,
He paid a total of $25.75.
⇒ 1.20b + 0.55d = 25.75 .........(2)
Now,
Multiply equation (1) by 1.20 , we get
1.20( b + d = 35 )
⇒1.20b + 1.20d = 42 ..........(3)
Now,
Subtract equation (2) from equation (3), we get
1.20b + 1.20d - ( 1.20b + 0.55d ) = 42 - 25.75
⇒1.20b + 1.20d - 1.20b - 0.55d = 16.25
⇒0.65d = 16.25
⇒d = 
= 25
⇒d = 25
Put the value of d in equation (1) , we get
b + d = 35
⇒b + 25 = 35
⇒b = 35 - 25 = 10
⇒b = 10
∴ we get
Number of bagels = b = 10
Number of donuts = d = 25
Answer: FALSE
Step-by-step explanation:
An Irrational number is a decimal t hat is non repeating while a rational number is s repeating decimal.
Question 1:Use the Pythagorean theorem.
If
, then the angle is acute.
If
, then the angle is right.
If
, then the angle is obtuse.
Thus, the angle is acute.
Question 2:Take the square root of the area to get the side length.
That's the side length. Since we have a 45-45-90 right triangle if we divide the square across its diagonal, we just multiply the side length by the square root of 2 in order to get the diagonal length.
Your answer is 20 m. Hope this helps! :)
The answer is D because the median is 4, the mean is 4, and the range is 4
Answer: $3.50 per week
Total money needed: $32
Money saved already: $18
$32 - $18 = $14
Money left to save: $14
-
Money left to save: $14
Time left to save: 4 weeks
$14 / 4 = $3.50 per week
Have a nice day!
