Answer:
13/2 or 6 1/2
Step-by-step explanation:
We can write the question in the form of an equation:
13/16 = n×1/8
Multiplying by 8 gives ...
8×13/16 = n
13/2 = n = 6.5
The number of 1/8 in 13/16 is 6 1/2 or 13/2.
For all values of x,
f(x) = x^2 + 3x and g(x) = x - 4
Show that fg(x) = x^2 - 5x + 4
Answer:
f(g(x)) = x² - 5x +4
Step-by-step explanation:
Explanation
Given that the functions
f(x) = x² + 3 x and g(x) = x-4
f(g(x)) = f(x -4) (∵ g(x) = x-4)
= (x-4)² + 3(x-4)
= x² - 2(4)x + 4² + 3x -12
= x² - 8 x + 16 + 3x -12
= x² - 5x +4
∴ f(g(x)) = x² - 5x +4
Rewrite in simplest terms: 4(- 5u + 3) - 4(8u - 1)
Answer:
Step-by-step explanation:
-20u+12-32u+4
-52u + 16
Answer:
-52u + 16
Step-by-step explanation:
4(- 5u + 3) - 4(8u - 1)
= -20u + 12 - 32u + 4
= -52u + 16
Drag the tiles to the boxes to form correct pairs.
Match each pair of lines to the correct description
parallel lines
EF and CD
perpendicular lines
GH and EF
neither parallel nor
perpendicular lines
AB and CD
When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1
i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅
To find the slope of a line, we divide the vertical distance by the horizontal distance.
We'll use the trial and error method to find the right pairing
Let's start with A(3, 3) and B(12, 6)
Vertical distance =
Horizontal distance =
The slope AB = ³/₉ = ¹/₃
We want BC to have a slope -1 ÷ ¹/₃ = -3
Try C(16, -6); check the slope with B(12, 6)
Vertical distance =
Horizontal distance =
Slope of BC = -12 ÷ 4 = -3
The slope BC = -3 is the value we want so, tile 1 pair with tile 4
-------------------------------------------------------------------------------------------------------------
Let's do A(-10, 5) and B(12, 16)
Vertical distance = 16 - 5 = 11
Horizontal distance = 12 - -10 = 22
Slope AB = ¹¹/₂₂ = ¹/₂
The perpendicular slope would be -1 ÷ ¹/₂ = -2
Try C(18, 4) with B(12, 16)
Vertical distance = 16 - 4 = 12
Horizontal distance = 12 - 18 = -6
Slope BC = ¹²/₋₆ = -2
Slope BC and slope AB perpendicular, so tile 3 matches with tile 6
--------------------------------------------------------------------------------------------------------------
Let's try A(12, -14) and B(-16, 21)
Vertical distance = 21 - -14 = 35
Horizontal distance = -16 - 12 = -28
The slope AB = ³⁵/-₂₈ = ⁵/₋₄
We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅
Try C(-11, 25)
Vertical distance with B = 25 - 21 = 4
Horizontal distance with B = -11 - -16 = 5
The slope = ⁴/₅
Tile 7 matches tile 8
--------------------------------------------------------------------------------------------------------------
Take A(-12, -19) and B(20, 45)
Vertical distance = 45 - -19 = 64
Horizontal distance = 20 - -12 = 32
Slope AB = ⁶⁴/₃₂ = 2
We need the perpendicular slope to be -1 ÷ 2 = -¹/₂
We have C(6, 52) and checking the slope with B(20, 45)
Vertical distance = 45 - 52 = -7
Horizontal distance = 20 - 6 = 14
The slope is ⁻⁷/₁₄ = -¹/₂
Tile 9 pairs with tile 2
-----------------------------------------------------------------------------------------------------------
Conclusion
Tile 1 ⇒ Tile 4
Tile 3 ⇒ Tile 6
Tile 7 ⇒ Tile 8
Tile 9 ⇒ Tile 2
Tile 5 and Tile 10 do not have pairs
Answer:
Parallel lines = AB and CD
Neither parallel nor perpendicular lines = GH and EF
Perpendicular lines = EF and CD

Step-by-step explanation:
Calculate the clothing insulation (CLO) rating required to keep an average-sized man (surface area = 19.565 ft2) warm, while performing callisthenic exercises outside for 1 hour at a metabolic rate of 4.0 MET, where the ambient temperature is 41 degrees F, and the wind speed is negligible? The standard amount of insulation required to keep a resting person warm in a windless room at 70°F is equal to one CLO. The desired mean maintained normal temperature of skin is about 91°F, and 1 CLO = {[0.88 × Δ∘F × ft2 × hr.] / BTU}
Answer: the clothing insulation (CLO) rating required is 202.95
Step-by-step explanation:
Given the data in the question;
1 MET for an average sized man of surface area 19.565 ft²
1met = 18.48[ BTU/hr.ft²]
According to Ques;
1 CLO = 0.88[ Δ°F.hr.ft² / BTU ]
so
1 CLO = 0.88[ Δ°F×18.48 / 1MET ]
our Δ°F = temperature of the skin - ambient temperature = 91°F - 41°F = 50°F
MET = 4.0
therefore required CLO will be
CLO = 0.88[ 50 × 18.48 / 4.0 ]
CLO = 0.88 × 230.625
CLO = 202.95
Therefore, the clothing insulation (CLO) rating required is 202.95

One angle of a right triangle measures 78°. What is the measure of the other acute angle?
Answer:
12°
Step-by-step explanation:
a right triangle implies there is an angle that is 90°
another angle is 78°
the third angle is 180 - (90 + 78) = 180 - 168 = 12°

Step-by-step explanation:
3/2
Answer:
3/2
Step-by-step explanation:
The clearest points we can use from this graph are (60, 0) and (80, 30). Substitute those values into the slope formula to find the slope.
m = y₁ - y₂/x₁ - x₂
m = 0 - 30/60 - 80
m = -30/-20
m = 3/2
∴ The slope is 3/2.

Evaluate f(x)= -6+12 when x= -3,x=0, and x=1.
When x= -3, f(x)= , when x=0,f(x)= , and when x=1,f(x)= .
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.

Which expression is equivalent to
1.5(x + 3) + 3.8(7x –2)? Be sure to show all
steps of simplifying after picking an answer choice.
4.5x – 8.8
12.3x + 1
28.1x – 3.1
28.1x + 1
explain why also!
Answer:
28.1x – 3.1
Step-by-step explanation:
1.5(x + 3) + 3.8(7x –2)
Open the parenthesis
= 1.5x + 4.5 + 26.6x - 7.6
Simplify
= 28.1x - 3.1
Therefore, the equivalent expression to 1.5(x + 3) + 3.8(7x –2 is 28.1x - 3.1

An ice hockey puck is in the shape of a cylinder with a radius of 3.8 cm, and a thickness of 2.5 cm.
It is made out of rubber with a density of 1.5 grams per cm ³
Work out the mass of the ice hockey puck.
Give your answer correct to 3 significant figures.
The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
The volume of the puck = π * radius² * thickness = π * 3.8² * 2.5 = 113.4115 cm³
Density = mass / volume
1.5 = mass / 113.4115
mass = 170 g
The mass of the ice hockey puck with the below dimensions and density of 1.5 g/cm² is 170 grams.
