Finding the missing side of an triangle?
Answer:
10.1119 m or √102.25 m
Step-by-step explanation:
Using our lovely Pythagorean theorem, a² + b² = c², we can find the value of x in this triangle.
Let's say that a = 4.8 and b = 8.9, then set c as x.
(4.8)² + (8.9)² = x²
23.04 + 79.21 = x²
x² = 102.25
x = √102.25
= 10.111874208...
≈ 10.1119

You are an office manager, and you need to buy a new
printer. You are looking at two options for the printer
model you like. A local electronics store offers the
model for $499.99 plus a 5% sales tax. An online store
offers the same model for $549.99 plus $22.95 for
shipping and no sales tax. You plan to use a coupon
for the online store for 10% off the purchase price
before the shipping fee.
What will be the final price of the better deal?
$472.49
$515.65
$517.94
$524.99
$572.94
First let's calculate the final price at the electronic store.
499.99*(1+0.05)≈524.99
Now let's calculate the final price online
(549.99+22.95)*(1-0.1)≈515.65
If we compare the two we can see that the online price is cheaper at around 515.65 dollar therefore the second choice is correct.

A recent survey by the American Automobile Association showed that a
family of two adults and two children on vacation in the United States will
pay an average of $247 per day for food and lodging with a standard
deviation of $60 per day. Assuming the data are normally distributed, if
the family had a z-score of 1.5, what was their daily expense for food and
lodging?
The daily expense for food and lodging will be 337.
What is the z-score?The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day.
Assuming the data are normally distributed if the family had a z-score of 1.5.
Then the daily expense for food and lodging will be
z = (x - μ) / σ
1.5 = (x - 247) / 60
90 = x - 247
x = 247 + 90
x = 337
The daily expense for food and lodging will be 337.

Show me the working out
Answer:
[tex]\sf{x=\dfrac{7}{2}=3.5 }[/tex]
Step-by-step explanation:
It is necessary to isolate the term of x from both sides in order to solve this problem.
First, subtract by 5 from both sides.
2x+5=12
[tex]\sf{2x+5-5=12-5}[/tex]
Solve.
[tex]\sf{12-5=7}[/tex]
2x=7
Divide by 2 from both sides.
2x/2=7/2
Solve.
Dividing is another option.
7/2=3.5
So, the final answer is 7/2=3.5.

Please help
Answer:
y=-4x-8
Step-by-step explanation:
use the equation y-y1=m(x-x1) and solve for y
Answer:
y=-4x-3
Step-by-step explanation:
For this, you would use the point-slope formula, which is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from the ordered pairs, and m being the slope. You can plug the values from the problem into the formula:
(y-5)=-4(x+2)
y-5=-4x-8
y=-4x-3

What is the equation of the translated function? f(x) = (x – 1)2 – 5 f(x) = (x 1)2 5 f(x) = (x – 5)2 – 1 f(x) = (x 5)2 1
The equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5
What will be the equation?The vertex of the original function is (0, 0 )
The vertex of the translated function is (- 1, 5 )
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
The translated graph has been shifted 1 unit left, thus
f(x) = (x + 1)²
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
The translated graph has been shifted 5 units up,
Thus the equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

Write 3 1/2 hours : 36min as a ratio in its simplest form
Answer:
Step-by-step explanation:
you can re-write 3 1/2 hours into minutes.
1 hr = 60 minutes,
Therefore:
3 1/2 hours = 3.5 times 60 = 210 minutes
So now we have the ratio:
3 1/2 hours : 36 minutes
210 minutes : 36 minutes
Both numbers can be divided by 6
210/6 = 35 and 36/6 = 6
So now we can re-write the ratio as :
35 : 6
Two linear equations
Answer:
x=3y-2
x+3y=6
if x value is above
place the value of x
3y-2+3y=6
3y+3y_=6+2=8
6y=8
y=8/6=4/3
y=4/3.
