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

Audrey already has 2 plants in her backyard, and she can also grow 1 plant with
every seed packet she uses. Write an equation that shows the relationship
between the number of seed packets x and the total number of plants y.
21:28 = :24
plz help....
Answer:
x=18
Step-by-step explanation:
21:28=x:24
1. rewrite: 21/28 = x/24
2. simplify: 3/4=x/24
3. multiply 24 to both sides: x=18
The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y – 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Oy=1x+2
Oy={x-4
O y = x + 3/2
Oy=2x-
2.
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
The slope-intercept form of the equation for this line is y = 1/2 x + 5/2
First, we need to get the slope of the equation passing through the coordinate (-9, -2) and (1, 3)
m = 3+2/1+9
m = 5/10
m = 1/2
The equation in point slope form is given as y - 3 = 1/2(x - 1)
2(y - 3) = x - 1
Write in slope intercept form
2(y - 3) = x - 1
2y - 6 = x - 1
2y = x + 5
y = 1/2 x + 5/2
Hence the slope-intercept form of the equation for this line is y = 1/2 x + 5/2

Plug in the value of x: [tex]y = (-10 - 1)^{2}[/tex] Solve what's in parentheses: -10 - 1 = -11Plug -11 in: [tex]y = -11^{2}[/tex] [tex]-11^{2} = 121[/tex] So, y = 121I hope this helps!
What is the account balance if the principle is $350 the annual rate is 4% and the time is 3 years.
Answer:
393.70
Step-by-step explanation:
350x.04= 14 for 1st year
350+14= 364 for 1st year
364×.04= 14.56 for 2nd year
364+14.56= 368.56 for 2nd year
368.56×.04= 15.14 for 3yr
368.56+15.14= 393.70 yr 3 yrs

© 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)

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
Solve the compound inequality 2x − 3 < 7 and 5 − x ≤ 8. A. x ≥ 3 and x < 2 B. x ≥ 3 and x < 5 C. x ≥ −3 and x < 2 D. x ≥ −3 and x < 5
Given:
The compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].
To find:
The solution for the given compound inequality
Solution:
We have, compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].
For [tex]2x-3 < 7[/tex],
Add 3 on both sides.
[tex]2x < 7+3[/tex]
[tex]2x < 10[/tex]
Divide 2 on both sides.
[tex]x< 5[/tex] ...(i)
For [tex]5-x \leq 8[/tex],
Subtract 5 from both sides.
[tex]-x \leq 8-5[/tex]
[tex]-x \leq 3[/tex]
Divide both sides by -1. So, the sign of inequality is changed.
[tex]x \geq -3[/tex] ...(ii)
Using (i) and (ii), we get the solution of given compound inequality as
[tex]x \geq -3[/tex] and [tex]x< 5[/tex]
Therefore, the correct option is D.
