Steve was trying to make it back to base. However he did not want to
travel through the Dark Oak Forrest. He moved 86 blocks vertically,
then he moved 44 blocks horizontally to arrive at the base. If Steve was
braver, he could have walked diagonally through the forrest. At what
angle, C, with the horizontal does the diagonal path make? Show all
work; only worked typed into the space below will be graded. (9
points)
Answer:
Angle C = 62.90°
Step-by-step explanation:
As given,
The perpendicular = 86
Base = 44
As, we know that
tan(C) = [tex]\frac{Perpendicular}{Base} = \frac{86}{44} = 1.9545[/tex]
⇒C = [tex]tan^{-1}[/tex](1.9545) = 62.90°
∴ we get
Angle C = 62.90°
The graph is as follows :
5.(x+3) = 2x-3 Help pls
Answer:
x= -6
Step-by-step explanation:
5.(x+3) = 2x-3
5x+15=2x-3
5x-2x+15=-3
5x-2x=-3-15
3x=-3-15
3x=-18
x=-6
Step-by-step explanation:
5(X+3) =2X_3
Expand the brackets
5X + 15 = 2X _ 3
CLT(Collect like terms)
5X_2X= _3 _ 15
3X = _ 18
DBS( Divide both sides) by 3
3X/ 3 = _18 / 3
X = _9
A typical tip in a restaurant is 15% of the total bill. If the bill is $60, what would the
typical tip be?
The typical tip would be $
Answer:
$9
Step-by-step explanation:
15% is equal to 15/100
the word "of" means multiplication
15% of $60 is like saying:
15/100 * $60 = $9
What is the value of the expression 10 + (fraction 1 over 2)4 ⋅ 48?
12
13
16
18
Answer:
i think you wrote the equation wrong because the answer is 106
Step-by-step explanation:
10+(1/2)4x48 solve using system of equations
multiplying is first (1/2)x4=2
10+2x48
multiply again 2x48=96
10+96=106

How do you solve 2.5x + 10 = 50?
Answer:
I think the answered is x = 16 hope I right
Answer:
X = 16
Step-by-step explanation:
2.5x+10 = 50
distribute the ten to the other side by substracting
2.5x = 50-10
2.5x = 40
Now divide 2.5 on both sides
2.5x/2.5 = 40/2.5
x = 16

I hope it helpss!!!!!!! :)
Help me pls pls pls
Answer / Step-by-step explanation:
4 * (2 + 3) - 12
To get our final answer, we need to follow PEMDAS, which is :
Parenthesis
Exponent
Multiply
Divide
Addition
Subtraction
These mean that this is the order you will solve by what is in the question, let us start with the parenthesis.
(2 + 3) fits this description, therefore we add them together :
4 * 5 - 12
There are no more parenthesis and also no more exponents, so move onto multiplying.
4 * 5 - 12
20 - 12
Now subtract :
8
Please help ASAP math
Answer:
(1,-4)
Step-by-step explanation:
First manipulate the second equation so that y is by itself
x-y=5
-y=-x+5
y=x-5
then substitute that y in for the y in the above equation and solve for y
y=-2x-2
x-5=-2x-2
3x-5=-2
3x=3
x=1
Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations
y=-2x-2
y=-2(1)-2
y=-2-2
y=-4
I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.
whats the value of (-6)(2)+(-8÷4)
Answer:
-14
Step-by-step explanation:
(-6)(2) = -12
(-8÷4) = -2
-12 + -2 = -14
Therefore, (-6)(2)+(-8÷4) = -14

Find the perimeter of the triangle with vertices D(5, 6), E (10, 9), and F(7, 11). Do not
round before calculating the perimeter. After calculating the perimeter, round your
answer to the nearest tenth.
The perimeter is
units.
Answer:
Perimeter of triangle = 14.82 approx.
Step-by-step explanation:
Given:
D(5, 6)
E (10, 9)
F(7, 11)
Find:
Perimeter of triangle
Computation:
Distance = √(x1-x2)² + (y1-y2)²
Perimeter of triangle = DE + EF + FD
Perimeter of triangle = √(5-10)² + (6-9)² + √(10-7)² + (9-11)² + √(7-5)² + (11-6)²
Perimeter of triangle = √25 + 9 + √9 + 4 + √4 + 25
Perimeter of triangle = √34 + √13 + √29
Perimeter of triangle = 5.83 + 3.6 + 5.3851
Perimeter of triangle = 14.8151
Perimeter of triangle = 14.82 approx.

Step-by-step explanation:
Ricky ate 2 soft tacos, and 4 of his friends ate s soft tacos. If there were 18 2 points
soft tacos in all, how many soft tacos did his friends eat if each friend ate
the same amount? Ricky wrote the following equation to find the number
of soft tacos each friendate, 6s = 18. He then found out, from dividing that
each friend ate 3 tacos each. Do you agree/disagree with Ricky's thinking?
Explain.
Your answer
Your
Use the following table to answer questions #3, #4, and #5.
Answer:
Each friend ate 4 tacos.
Step-by-step explanation:
"4 of his friends ate s tacos" is unclear. I assume it should be
"4 of his friends ate s tacos each."
total tacos = 2 + 4s = 18
4s = 16
s = 4
His four friends ate a total of 16 tacos, each friend eating 4 tacos.
Ricky's reason, i.e., that 6s = 18, is incorrect.
6s = 4s+2s, where 4s is what his friends ate in total.
That implies that Ricky ate 2s tacos, instead of 2 tacos. If 2s = 2 then s = 1, but then 6s ≠ 18.
The volume of a cone is 108 pi cubic inches. Its height is 4 inches. What is the radius of the cone? Round the answer to the nearest tenth if necessary.
5.2 in.
9 in.
34.7 in.
81 in.
Answer:
Step-by-step explanation:
V = 108π in³
h = 4 in
r = √(3V/(πh)) = 9 in
Answer:
B
Step-by-step explanation:
If you have 108 pi and then you divided it to find the radius and all that stuffy stuff you will end up getting 9 and if you dont want to do it that way just substitute each one of the answer chooses as the radius until the volume gets you 108 pi cubic inches.

(x + 5)(x – 5)
Multiply
Answer:
[tex] {x}^{2} - 25[/tex]
Step-by-step explanation:
[tex](x + 5)(x – 5) \\ \\ = {(x)}^{2} - {(5)}^{2} \\ \\ = {x}^{2} - 25[/tex]
Answer:
x²-25
Step-by-step explanation:
To do a sum like this, break up the first bracket and multiply by the second (terms from the first bracket is in bold in first few steps for clarity):
(x + 5)(x – 5)
x(x-5)+5(x-5)
x²-5x+5x-25
x²-25
A line goes through the point (-8,9), and has a slope of 3/4
Write in form of a Ax + B and C for this line
Answer:
[tex]y=\dfrac{3}{4}x+15[/tex]
Step-by-step explanation:
Given that,
A line goes through the point (-8,9), and has a slope of 3/4.
We need to express in the form of Ax+B for this line.
We have, m = 3/4
So,
[tex]y=\dfrac{3}{4}x+B[/tex]
Put y = 9 and x = -8 in the above equation.
[tex]9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15[/tex]
So,
[tex]y=\dfrac{3}{4}x+15[/tex]
It is the required equation of the line.
Temperature Change In the United States, temperature is measured on the Fahrenheit temperature scale. On this scale, water boils at 212 degrees and freezes at 32 degrees. To denote a temperature of 32 degrees on the Fahrenheit scale, we write:
32 degrees F, which is read "32 degrees Fahrenheit"

A. Write the temperature as a negative number Ans: ———-
degrees Fahrenheit.
B. B.) An hour later it has warmed up by 8 degrees. What is the temperature at 11:00 that morning? Ans: _____degrees Fahrenheit.
Answer: B
Step-by-step explanation:
Find the value of x. If your answer is not an integer, express it in simplest radical form.
Step-by-step explanation:
[tex]4 \\ {x}^{2} = {16}^{2} + {14}^{2} \\ {x}^{2} = 256 + 196 \\ {x}^{2} = 452 = 2 \sqrt{113} = 21.26[/tex]
[tex]5 \\ {x}^{2} = {8}^{2} + {15}^{2} \\ {x}^{2} = 64 + 225 \\ {x}^{2} = 289 \\ x = 17[/tex]
