Volume of the bottom rectangle:
12 x 4.5 x 5.5 = 297 cubic cm
Volume of triangle:
1/2 x 12 x 5 = 30 x 4.5 = 135 cubic cm
Total volume = 297 + 135 = 432 cubic cm
Answer:
y=1/3x+10/3
Step-by-step explanation:
y-y1=m(x-x1)
y-5=1/3(x-5)
y=1/3x-5/3+5
y=1/3x-5/3+15/3
y=1/3x+10/3
-12 + 9 - (-3) - 11
Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract
1st step: PEM
-(-3) is actually -1 * -3 = + 3
-12 + 9 + 3 - 11
2nd step: D is not possible, so we do A.
9 + 3 = 12
3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.
In step 1, the commutative property of addition is used since x + 5 is just equal to 5 + x
In step 2, the associative property of addition is used since x is grouped to the last term.
In step 3, the distributive property of multiplication is used since 3 is multiplied to the terms inside the parenthesis.
In step 4, multiplication is done.
Answer:
c< 7
Step-by-step explanation:
the product of c and 7 is less than 49
Product means multiply
7c< 49
Divide each side by 7
7c/7 < 49/7
c< 7
