5) A rectangular box 25cm by 20cm by 15cm internally is made of wood
0.5cm thick. If the box has a lid, find the volume of the wood used in cm'.
Answer:
The volume of the wood used is [tex]1,116\ cm^3[/tex]
Step-by-step explanation:
The Volume of a Rectangular Cuboid
In a rectangular cuboid, all angles are right, and the opposite faces are equal.
The volume of a cuboid of dimensions a,b,c is:
V=a.b.c
The rectangular box is made of wood with externals dimensions of 25 cm by 20 cm by 15 cm.
The external volume of the box is:
[tex]V_e=(25)*(20)*(15)=7,500\ cm^3[/tex]
The walls of the box are 0.5 thick each, this means that the internal dimensions are 1 cm less than the external dimensions, including the lid.
Thus the internal volume is:
[tex]V_i=(24)*(19)*(14)=6,384\ cm^3[/tex]
The volume of the wood used is the difference between the external and the internal volumes:
[tex]V_w=7,500\ cm^3-6,384\ cm^3=1,116\ cm^3[/tex]
The volume of the wood used is [tex]\mathbf{1,116\ cm^3}[/tex]

prove that cotx + coty = sin(x+y)/sin x sin y
Answer:
change L.H.S in terms of sin and cos
Step-by-step explanation:
so we know cot x= cos x/sin x. so similarly we have cot y = cos y / sin y. since we have our cot in terms of cosine and sine, get a L.C.M and solve it further.

Answer:
6z - 6
Step-by-step explanation:
When you expand you are removing brackets. This means you multiply the outer number by the ones inside thus:
2(3z-3)
2 times 3z is 6z .
2 times 3 is 6.
So the answer is 6z - 6.

Solve the following inequality for g. Write your answer in simplest form.
-5-3(5g-4)≥2g+6-10
Answer:
[tex]g\leq \frac{11}{17}[/tex]
Step-by-step explanation:
[tex]-5-3(5g-4)\geq 2g+6-10\\-5+(-15g+12)\geq 2g-4\\-5+(-15g)+12\geq 2g-4\\7-15g\geq 2g-4\\7\geq 17g-4\\3\geq 17g\\\frac{11}{17} \geq g\\g\leq \frac{11}{17}[/tex]
The value of g in the given inequality -5-3(5g-4) ≥ 2g+6-10 is equal to or less than 11/17, g ≤ 11 / 17
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given is an inequality -5-3(5g-4) ≥ 2g+6-10
Solving for g,
-5-3(5g-4) ≥ 2g+6-10
-5-15g+12 ≥ 2g+6-10
-15g+7 ≥ 2g-4
7 ≥ 17g -4
11 ≥ 17g
11 / 17 ≥ g
g ≤ 11 / 17
Hence, the value of g is equal to or less than 11/17, g ≤ 11 / 17

Write in slope-intercept form an equation of the line that passes through the given points. (-1, -1) (1, 5)
Step 1: We need to find the slope (or m) FIRST using slope formula*.
[tex]m = \frac{5 - (-1)}{1 - (-1)}\\\\m = \frac{6}{2} = 3[/tex]
m = 3
Step 2: Now we find the y-intercept (or b) using the slope-intercept formula**, ONE of the 2 points given, and the slope we just found.
[tex]5 = 3(1) + b\\\\5 = 3 + b\\\\2 = b[/tex]
b = 2
Step 3: Now we put it all together we get our equation in slope-intercept form**.
[tex]y = 3x + 2[/tex]
**Slope-intercept form: [tex]y = mx + b[/tex]
*Slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Answer:
Angle 1- 130 degrees
Angle 3- 130 degrees
Angle 5- 50 degrees
Angle 6- 130 degrees
Step-by-step explanation:
Okay so. Angle 1 and 2 are on the same horizontal line. A line is 180 degrees. If two is 50 degrees then you subtract 50 from 180. Angles 2 and 4 are diagnol, which means that they are congruent, aka, the same, as are angles 1 and 3. 5678 and 1234 are the same. 1=8 2=5 3=6 and 4=7.
describe how to find the sums -4 + 2 and -4 + (-2) on a number line
Answer:
For -4, the arrow from zero goes 4 points to the left. Add two more.
Step-by-step explanation:
Answer:
-4 + 2 = -2 and -4 + (-2) = -6
Step-by-step explanation:
-4 + 2 = -2
On the number line,start at zero
Do 4 jumps to the left (you are at -4)
Then do 2 jumps to the right You are at -2
-4 + (-2) = -6
On the number line,start at zero
Do 4 jumps to the left (you are at -4)
Then do 2 more jumps to the left You are at -6

(sinA + cosA)/ (secA + cosecA) = sinA* cosA
Answer:
Proof below
Step-by-step explanation:
Trigonometric Identities
We'll prove that:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A[/tex]
Recall:
[tex]\displaystyle \sec A =\frac{1}{\cos A}[/tex]
[tex]\displaystyle \csc A =\frac{1}{\sin A}[/tex]
Applying those definitions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}[/tex]
Adding the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}[/tex]
Dividing the fractions:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}[/tex]
Simplifying:
[tex]\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A[/tex]
Hence proved

the sum is when you add two numbers together. so you would add t with 3 and out it in parentheses so you make sure that happens first. then you add it to 8 since 8 is being increased by the sum.
Mike had $8.25 in his account. He deposited $2.25 on Tuesday. He then withdrew $5.75 for lunch on Wednesday. How much money does Mike have left in his account.
Show your work on how you got your answer
Answer:
$4.75
Step-by-step explanation:
(had) 8.25 + (deposited) 2.25 = (total) 10.50
10.50 - (withdrew) 5.75 = (total left) 4.75
Answer:
$4.75
Step-by-step explanation:
(Deposit: Add, put in/Withdraw: subtract, take out)
Add $8.25 + $2.25 and you get $10.50. Now subtract that number with $5.75, so $10.50 - $5.75 is a total of $4.75. Mike has $4.75 left in his account.
