Answer:
1st option is the answer
Step-by-step explanation:
blue line: slope is 1 and y-intercept is 1; therefore equation is y= x + 1
red line: slope is -1 and y-intercept is -3; therefore equation is y= -x - 3
Answer:
9 hr * 60 min/hr = 540 min. 540 min * 60 sec/min = 32,400 sec. Use the method described by panic mode: round the number down until there is only one non-zero digit left. Here, 32,400 rounds down to 30,000. Now count the number of zeroes; the result is the order of magnitude: 4. (You see this in scientific notation also: 30,000 = 3 × 10^4.)
Answer:
D
Step-by-step explanation:
plug in (3,2) to see if it's a solution:
A) does -3(3) + 2 equal -7? yes
B) since 'A' is a solution then 'B' cannot be the answer
C) since (3,2) is a solution then 'C' cannot be the answer
plug in (2,-1) to see if it's a solution:
plug in (2,-1) to see if it's a solution:
-3(2) - (-1) equal -7? no, it equals -5
only (3,2) is a solution so the answer is D
The answer is
date
1 2 3 4 5 31
r1 r2 r3 r4 r5 . . . r31
1gm 2gms 3<span>gms 4gms 5gms . . . 31gms
r1+r2+ .... +r31= 31(31+1) /2=496gms (31 rings)
he only made 5 rings
31 rings----------> 496 gms
5 rings ------------> ? = 5 x496 / 31=80 gms
</span><span> the weights of those 5 rings was 80 gms</span>
Answer:
2037.89
Step-by-step explanation:
The area of a circle is πr²
This means that the area of the pizza is π*17.5^2
This means that the area =962.11275016187
We then need to find the area of a rectangle which is shown throuhg lenght*width
50*60=3000
We then need to find out the area of the box excluding the pizza so we subtract the area of a pizza
so we have
3000-962.11275016187=2,037.88724983813
Round and get 2037.89
