Step-by-step explanation:
5) = 0 (-17 + 20 = 3,... 3 + -3 = 0)
6) = -34 (-34 + 25 = -9,... -9 + -25 = -34)
9) = -4 (7 + -11 = -4)
Chow,...!
Answer:
for question 5 the answer is 0.
for question 6 the answer is -34.
for question 9 the answer is -4.
Step-by-step explanation:
question 5: -17+20 can also be written as 20-17 which is equal to 3. Next, we have to add 3 with -3. 3+(-3) is the same as 3-3 which equals 0.
question 6: 25-25 = 0, and the remainder is -34.
question 9: 7-11 can also be written as -11+7, which is equal to -4.

Which is better to buy? 3-yard roll of wrapping paper for $7.02. 8-foot roll of wrapping paper for $7.36
Answers
Answer:
3 yard roll of wrapping paper for $7.02 is better to buy.
Step-by-step explanation:
1 yard = 3 foot
3 yard = 9 foot
$7.02 / 9 foot = $0.78/foot
$7.36 / 8 foot = $0.92/foot
0.78 < 0.92
Therefore, 3 yard roll of wrapping paper for $7.02 is better to buy.
The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase to 1.4m. the length of the extra plank of wood that was added is Select one a. 2. 4 b. 1 C. 1.25 d. 1.75V
Answers
Answer: Hello There!................
Mean = Sum of observation / total number of observation
Mean = 1.35m
1.35 = Sum of length of 7 wood planks/ 7
1.35*7 = Sum of the length of 7 wood planks
9.45 = Sum of the length of 7 wood planks
Let the length of extra added wood plank = x
So,
(Sum of the length of 7 wood planks + x) / 8 = 1.4m
(9.45 + x) / 8 = 1.4
9.45 + x = 1.4 * 8
9.45 + x = 11.2
x = 11.2- 9.45
= 1.75
So,
The length of extra added wood plank = 1.75m

[tex]$\csc t-\frac{2}{\sqrt{3} }[/tex]
[tex]\sec t=2[/tex]
[tex]\cot t=\frac{1}{\sqrt{3} }[/tex]
Step-by-step explanation:
Given:
[tex]\sec(t)=2[/tex]
The terminal point of [tex]t[/tex] is in Quadrant [tex]IV[/tex]
Step 1:
To find the values of trigonometric functions of t
[tex]\sec(t)=\frac{H}{A}[/tex]
[tex]=\frac{2}{1}[/tex]
Analyze the figure and find the value of O
[tex]t[/tex] ∈ [tex]IV[/tex]
[tex]O=\sqrt{2^{2}-1^{2} }[/tex]
[tex]=\sqrt{4-1}[/tex]
[tex]=\sqrt{3}[/tex]
Step 2:
[tex]$\sin t=-\frac{O}{H}[/tex]
[tex]=-\frac{\sqrt{3} }{2}[/tex]
[tex]\cos t=\frac{A}{H}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\tan t=-\frac{O}{A}[/tex]
[tex]=-\sqrt{3}[/tex]
[tex]$\csc t=-\frac{H}{O}[/tex]
[tex]=-\frac{2}{\sqrt{3} }[/tex]
[tex]\sec t=\frac{H}{A}[/tex]
[tex]=\frac{2}{1}[/tex]
[tex]\cot t=-\frac{A}{O}[/tex]
[tex]=\frac{1}{\sqrt{3} }[/tex]

E is the midpoint of DF, DE = 3x + 4 and EF = 5x - 2. Find DE, EF, and DF.
Answers
Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.
DE = 3x + 4
EF = 5x - 2
DE = EF
DE + EF = DF
Now, let's plug our values for DE and EF into our first expression.
3x + 4 = 5x -2
Add 2 to both sides and subtract 3x from both sides.
6 = 2x
Divide both sides by 2
3 = x
Let's plug 3 in for x into DE.
DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13
DE = EF = 13
We can plug 13 in for DE and EF to get DF
DF = DE + EF = 13 + 13 = 26

0.10x + 0.25(24 - x) = 4.50
Answers
Answer:
10
Step-by-step explanation:
So you start with
0.10x+0.25(24-x)=4.50
First you do the parenthesis
.25x24 is 6.
So
.10x+6-.25x=4.5
Combine like terms
-.15x+6=4.5
Now isolate the x so you can find what x is
4.5-6
-.15x=-1.5
Then divide
-1.5/-.15
The two negatives make it positive
So 1.5/0.15
Comes to 10.
x=10
The 10 comes like this .15 is 15/100
Simplify that to 3/20
1.5 is 15/10
Simplify that to 3/2
Then divide those
3/2 ÷ 3/20
You cant divide fractions so flip the other side and multiply
3/2 × 20/3
60/6
10

Answer:
x = 10
Step-by-step explanation:
