It’s d because the slope is negative and it is 2/1 which can also be written as just 2. in the formula y=mx+b, m is the slope and b is the y-intercept. the y-intercept is where the line touches the y axis(in this case -1) so it would be written as y=2x+(-1)
Answer:
Step-by-step explanation:
length of rectangle = circumference of circle = πd = 6π cm
area of rectangle = 2×6π = 12π cm
area of one circle = πr² = 9π cm²
surface area = 12π + 2(9π) = 30π ≅ 90 cm²
Answer:
112 ounces
Step-by-step explanation:
Malia bought 14 cans of cat food
Each of the can weighs 8 ounces
Therefore the total ounces of cat food bought can be calculated as follows
= 14×8
= 112 ounces
Answer:
-2.8 x 10^5 or -280,000
Step-by-step explanation:
We first have to look at:
<em>P </em>: Parenthesis
<em>E </em>: Exponents
<em>M </em>: Multiply
<em>D </em>: Divide
<em>A </em>: Add
<em>S </em>: Subtract
We have to solve the question in that order:
The first thing we do is figure out the value of the exponents from left to right since there are exponents inside the parenthesis.
10^4 is just 10x10x10x10 = 10,000
10^5 same thing 10x10x10x10x10 = 100,000
Now that we know the value of the exponents we can solve the equations inside the parenthesis:
12 x 10,000 = 120,000
(120,000) - ( 4 x 100,000)
4 x 100,000 = 400,000
So the final expression is:
<u>(120,000) - (400,000) = -280,000</u>
