Step-by-step explanation:
you add all the numbers then subtract by the number of number
Answer: 86 minutes
Step-by-step explanation:
To find the mean of something, you always add up the values and then divide by the amount.
So, in total there are 430 minutes because (170+150+45+30+35=430)
There are five different towns.
430/5=86

Quotient is the answer to a division problem, so we need to find a problem that needs to divide x and y to find the answer. It isn't A or B, since they are asking for y, not the quotient. I have no idea what D is. C makes sense, so C might be the answer.
It tells us how much time he has(x), and how long it takes him to make 1 bag(y), and we need to find the answer, which is the quotient.
So C is the answer.

Determine the length of GH. Round to the nearest tenth.
3.9 cm
G
52
642
H
Answer:
|GH| = 5,7 cm
Step-by-step explanation:
To know |GH|, you first need to find the length of |GD|.
We can calculate |GD| by;
cosG = |GC| / |GD|
<=> |GD| = |GC| / cosG
=> |GD| = 3,9 cm/ 0,62 = 6,33 cm
We now can easily calculate |GH| with the sinus of angle D;
sinD = |GH| / |GD|
<=> |GH| = sinD.|GD|
=> |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

Step-by-step explanation:
In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted? (1 point)
Group of answer choices
Down 5, left pi over 2
Up 5, left pi over 2
Up 5, right pi over 2
Down 5, right pi over 2
Answer:
The first option:
Down 5, left pi/2.
Step-by-step explanation:
Let's define the translations in a general way.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
if N is positive, the shift is to the left.
if N is negative, the shift is to the right.
Vertical shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x) + N
If N is positive, the shift is upwards.
If N is negative, the shift is downwards.
In this case, we have the function:
f(x) = 6*Sin(2*x + π) - 5
Where the original function was something like:
h(x) = 6*sin(2*x)
Here we can already see the vertical shift is of minus 5 units, so the shift is 5 units down.
then we get:
f(x) = h(x) - 5 = 6*sin(2*x) - 5
Now we can apply a shift to the left of π/2 units, so we get:
f(x) = h( x + π/2) - 5 = 6*sin(2*(x +π/2) ) - 5
f(x) = 6*sin(2*x +π ) - 5
Then the correct option is:
Down 5, left pi over 2

Ms. Lang lives In St.Paul, Minnesota. Last year, she made 4 round trips to Maddison, Wisconsin, and 3 round trips to Bismarck, North Dakota. How many more miles did she travel in her trips to Bismarck than in her trips to Maddison?
Answer:
542 miles
Step-by-step explanation:
St. Paul to Madison, Wisconsin = 260 miles
St Paul to Bismarck, North Dakota = 437 miles
4 round trips to Madison = 4 * 2 * 260 = 2080 miles
3 round trips to Bismarck = 3 * 2 * 437 = 2622 miles
Difference in miles traveled :
2622 miles - 2080 miles = 542 miles
Answer:
542 miles
Step-by-step explanation:
St. Paul to Madison, Wisconsin = 260 miles
St Paul to Bismarck, North Dakota = 437 miles
4 round trips to Madison = 4 x 2 x 260 = 2080 miles
3 round trips to Bismarck = 3 x 2 x 437 = 2622 miles
Difference in miles traveled:
2622 miles - 2080 miles = 542 miles

Find the volume of a cuboid with sides that measure two centimetres, three centimetres and seven centimetres
Answer:
Volume of a cuboid = 42 cm³
Step-by-step explanation:
Volume of a cuboid = side A × side B × side C
Side A = 2 cm
Side B = 3 cm
Side C = 7 cm
Volume of a cuboid = side A × side B × side C
= 2 cm × 3 cm × 7 cm
= 42 cm³
Volume of a cuboid = 42 cm³

Answer:
m∠N = 72°
mNQ = 94°
Step-by-step explanation:
An inscribed angle is equal to half the measure of its intercepted arc
∠N is an inscribed angle and arc MP is it's intercepted arc
Thus, ∠N = 1/2 arc MP
if arc MP = 144
Then ∠N = 144/2
144/2 = 72
Hence, ∠N = 72°
For ∠P and arc NQ we are given the measure of the inscribed angle and need to find the measure of the intercepted arc.
If the measure of an inscribed angle equals half the measure of its intercepted arc, then the measure of the intercepted arc equals twice the measure of the inscribed angle.
Thus, arc mNQ = 2(∠P)
If ∠P = 47, then mNQ = 2(47)
2 * 47 = 94
Hence, mNQ = 94
