Answer: 3.5 hours
Step-by-step explanation:
From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:
= 320 + 820
= 1140 calories
The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:
= 1140/326
= 3.5 hours

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.

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.

Step-by-step explanation:
Dan: Paul = 9:5
Dan £9x, Paul £5x
9x-26=5x+26
9x-5x=52
4x=52
x=13
9x=117
5x=65
paul had £5x=£65
STEPS
1)
1. Write the coordinates of the 1st and
2nd points.
2. Label the coordinates of the first point
as
(X1,Y1) and the 2nd point as (X2
Y2).
3. Use the formula
m=Y2-Y
X2 - X
1st Point 2nd Point
1st Point:
2nd Point:
m=Y-Y
X2 - X
m=Y-Y
X2 - X
Answer:
The first point is right in the origin, so it's (0,0)
Our second point is (2, 1)
Our first point (0,0) would look like if labeled
0(X1) , 0(Y1)
Our second point would look like if labeled
2(X2) , 1(Y2)

Answer:
Below.
I Hope it helps :)
Step-by-step explanation:
Slope intercept form :
y=mx+b
1.
[tex]2x + y = 1[/tex]
Slope intercept form :
[tex]y = - 2x + 1[/tex]
Equation :
[tex]x - 2y = 8[/tex]
Slope intercept form :
[tex] - 2y = - x + 8[/tex]
or
[tex] y = \frac{1}{2} x - 4[/tex]
2.
[tex]3x + 2y = 4[/tex]
Slope intercept form :
[tex]2y = - 3x + 4 \\ [/tex]
Divide through by 2
[tex]y = - \frac{3}{2} x + 2[/tex]
Equation :
[tex]x + 2y = - 4[/tex]
Slope intercept form :
[tex]2y = - x - 4[/tex]
Divide through by 2
[tex]y = - \frac{1}{2} x - 2[/tex]
3.
[tex]4x + y = 1[/tex]
Slope intercept form =
[tex]y = - 4x + 1[/tex]
Equation :
[tex]x + y = - 2[/tex]
Slope intercept form :

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
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

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.

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

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.

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
