The figure above shows a cement block of
36 cm x 20 cm x 9 cm with two 10 cm x 8 cm
openings. What is the weight of the cement block
to the nearest gram? (The density of cement is
1.7 gram/cm
cm)
A) 5,040
B) 6,048
C) 7,560
D) 8,568
Answer:
D) 8,568Step-by-step explanation:
weight = (volume of block - volume of slots) x density of block
= (30 * 20 * 9) - (2 x (10 * 8 * 9)) x 1.7
= (5400 - 1440) x 1.7
= 8,568
Volume is a three-dimensional scalar quantity. The correct option is D, 8568 grams.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the complete block is,
Volume = 36 cm x 20 cm x 9 cm = 6480 cm³
The volume of the opening is,
Volume of the opening = 2 × 10 cm x 8 cm × 9cm = 1440 cm³
Therefore, the weight of the cement block to the nearest gram is,
Weight = (6480 -1440)cm³ × 1.7 gram/cm³
= 8568 grams

im failing Geometry if anyone is good at Geometry and want to help me i attached 5 problems i greatly appreciate anyone that helps
Answer:
x = 12
Step-by-step explanation:
Here we go!
What we know:
So 7x and 8x are part of a same side interior angle. meaning, they add up to 180°!
[tex]8x + 7x = 180[/tex]
Combine like terms
[tex]15x = 180[/tex]
Divide 15 from both sides
[tex]x = 12[/tex]
Let's check our work:
plug in x
7(12) + 8(12) = 180
multiply
84 + 96 = 180
add
180 = 180

© Stephen was thinking of a number. Stephen doubles it, then adds 11 to get an
answer of 47.7. What was the original number?
Answer:
18.35
Step-by-step explanation:
This is a question which requires you to work backwards.
Divide means multiply and vice versa
Addition means subtract and vice versa
First, we find the number before 47.7.
47.7-11=36.7
Secondly, we find the number before 36.7, aka the original number.
36.7/2=18.35 (/ sign means divide)

plz show work
Answer:
X = 7
Step-by-step explanation:
-11x - 6 + 20x = 57 (Collect like terms)
9x - 6 = 57 (Add 6 on both sides)
9x = 63 (Divide by 9 on both sides)
x = 7

-11(7) -6 + 20(7) = 57
-77 - 6 + 140 = 57
