Step-by-step explanation:
25) hypotenuse² = base² + altitude²
= 10² + 8²
= 100 + 64
= 164
hypotenuse = √164 = 12.8
Perimeter = 10 +8 + 8 + 12.8 + (12.8 -10)
= 10 + 8 + 8 + 12.8 + 2.8

find the surface area of 9yd 6yd
Answer:
198 square yards ( the surface area is 198 square yards )
Step-by-step explanation:
the length is 9yd, the width is 6yd the height is 3yd .
( 6x9+ 6x3+ 9x3 ) x2
= ( 54 + 18 + 27 ) x2
= 198
the surface area is 198 square yards.
Rectangular surface area = ( length x height + length x width + width x height ) x2
Smith Automotive needs to hire a new mechanic. They decide to place an
ad in the Springfield Herald. A classified ad in the Springfield Herald costs
$45 for the first five lines. There is a charge of $5 for each additional line.
Answer:
y = 45 + 5(x - 5)
where y is the total cost of the ad, and x is the total number of lines in the ad
Step-by-step explanation:
Let x = number of lines in the ad
Let y = total cost
If the cost of the ad is $45 for the first 5 lines and $5 for each additional line then the expression for the total cost of the ad is:
y = 45 + 5(x - 5)
Answer:
equation: y = 5(x-5) + 45
Explanation:
Here "y" represents the total money earned. "x" represents the earning from additional line. the constant variable is "45" and does not change.

Answer:
[tex]f(g(x))=x[/tex]
[tex]g(f^{-1}(x))=\dfrac{-1}{x-1}[/tex]
[tex]g^{-1}(x)=\dfrac{1}{1-x}[/tex]
Step-by-step explanation:
[tex]f(x)=\dfrac{1}{1-x} \ \ \textsf{and} \ \ g(x)=\dfrac{x-1}{x}[/tex]
[tex]f(g(x))=\dfrac{1}{1-(\frac{x-1}{x})}[/tex]
[tex]\implies f(g(x))=\dfrac{1}{\frac{x}{x}-\frac{(x-1)}{x}}[/tex]
[tex]\implies f(g(x))=\dfrac{1}{\frac{x-x+1}{x}}[/tex]
[tex]\implies f(g(x))=\dfrac{1}{\frac{1}{x}}[/tex]
[tex]\implies f(g(x))=x[/tex]
[tex]x=\dfrac{1}{1-y}[/tex]
[tex]\implies 1-y=\dfrac{1}{x}[/tex]
[tex]\implies y=1-\dfrac{1}{x}[/tex]
[tex]\implies f^{-1}(x)=1-\dfrac{1}{x}[/tex]
[tex]g(f^{-1}(x))=1-\dfrac{1}{1-\frac{1}{x}}[/tex]
[tex]\implies g(f^{-1}(x))=1-\dfrac{1}{\frac{x-1}{x}}[/tex]
[tex]\implies g(f^{-1}(x))=1-\dfrac{x}{x-1}[/tex]
[tex]\implies g(f^{-1}(x))=\dfrac{x-1-x}{x-1}[/tex]
[tex]\implies g(f^{-1}(x))=\dfrac{-1}{x-1}[/tex]
[tex]x=\dfrac{y-1}{y}[/tex]
[tex]\implies xy=y-1[/tex]
[tex]\implies 1=y-xy[/tex]
[tex]\implies 1=y(1-x)[/tex]
[tex]\implies y=\dfrac{1}{1-x}[/tex]
[tex]\implies g^{-1}(x)=\dfrac{1}{1-x}[/tex]

Angle p and q are complementary angles if m p=(3x+2)^0 and mq=(3x-8)^0 find the value of x m p and m q
Answer:
x = 16
Angle p = 50°
Angle q = 40°
Step-by-step explanation:
"complementary" means the angles add up to 90°.
So,
3x+2 + 3x-8 =90
combine like terms.
6x - 6 = 90
add 6
6x = 96
divide by 6
x = 16
If x = 16,
then Angle p=
3x + 2
= 3(16) + 2
= 48 + 2
= 50
Angle p = 50°
And,
Angle q
= 3x - 8
= 3(16) - 8
= 48 - 8
= 40
Angle q = 40°
Check:
40° + 50° = 90°

Answer:
A = 9πr = 4A = 1/4πr = 10Step-by-step explanation:
The given formula can be used to find the area when the radius is known.
r = 3, A = 3²π = 9π
r = 1/2, A = (1/2)²π = 1/4π
The formula can be solved to give the radius when the area is known:
r = √(A/π)
A = 16π, r = √(16π/π) = 4
A = 100π, r = √(100π/π) = 10

casey has the forgotten combination to a lock. the lock has three dials with numbers 1, 2, and 3 What is the probability that the combination starts with 2?
The probability that the combination starts with 2 is 1/3
ProbabilityProbability is the likelihood or chance that an event will occur.
Probability = expected/total outcome
The total outcome = 3! = 6
The expected outcome if the combination starts with 2 is given as 2! = 2
Pr(the combination starts with 2) = 2/6 = 1/3

If you launch the cannonball from the ground instead (hi=0), what does that change in the original equation?
Answer:
the value of hi changes from 58 to 0:
h(t) = -4.9t^2 +19.8t
Step-by-step explanation:
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.

Randy has 25% more money than Sandy, and 20% more money than Mandy, who has
$1800. How much money does Sandy have?
Based on the amount of money that Randy has more than Sandy and Mandy, the amount that Sandy has is $1,728.
First find out how much Randy has.
How much does Randy have?This can be found as:
= Amount that Mandy has x ( 1 + 20%)
= 1,800 x 1.2
= $2,160
How much does Sandy have?The amount that Sandy has is:
= Amount Randy has / ( 1 + 25%)
= 2,160 / 1.25
= $1,728

as a step by step problem?
Answer:
m=-2
Step-by-step explanation:
You want to isolate the variable on one side (m).
Divide each side by 7.
m+5=3
Subtract 5 from both sides
m=-2
Answer:
m = -2.
Step-by-step explanation:
First divide both sides by 7; m + 5 = 3.
Then subtract 5 from both sides; m = -2.
A shop sells 2 brands of sunflower seeds. Brand A's package is in the shape of a cone with radius 2.5 centimeters and height 10 centimeters. Brand B's package is in the shape of a square prism. The prism's height is 2.5 centimeters, and each side of the base measures 5 centimeters.
Which package contains more seeds? Explain it show your reasoning.
The square prism would contain more seed than the cone because it has a larger volume.
VolumeVolume is the amount of space occupied by a three dimensional shape or object.
The volume of cone = (1/3) * π * radius² * height = (1/3) * π * 2.5² * 10 = 65.45 cm³
The volume of square prism = base² * height = 5² * 2.5 = 62.5 cm³
The square prism would contain more seed than the cone because it has a larger volume.
