Answer:
11:29.
Step-by-step explanation:
10:47 - 11:00 is 13 minutes, which leaves 29 minutes. So then you add that to 11:00, 11:29.
Answer:11:29
Step-by-step explanation:
If Doug starts at 10:47 and sweeps for 42 minutes
First you add 42 minutes to the 47.
Remember there are 60 minutes in an hour.
So do 47+42=89
Next do 89-60 (because there are 60 minutes in an hour)
You get 29 minutes.
Add one to the 10
That makes 11:29

A tornado drops a piece of wood from a
height of 4,624 ft. If the equation for
height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the piece of
wood to hit the ground?
Answer:
Step-by-step explanation:
H(t) = -16[tex]t^{2}[/tex]+4.624 ( in feet)
0 = -16[tex]t^{2}[/tex] + 4,624
-4,624 = -16[tex]t^{2}[/tex]
-4,624 / -16 = [tex]t^{2}[/tex]
289 = [tex]t^{2}[/tex]
17 = t
so.. 17 seconds to hit the ground.. :)
The piece of wood 17 seconds takes to hit the ground.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
A tornado drops a piece of wood from a height of 4,624 ft.
Given that the equation for the height as a function of time is
h(t) = -16t² + initial height
Substitute height = 4,624 ft. in the equation,
h(t) = -16t² +4.624
At ground level, the value of h(t) is zero,
0 = -16t² + 4,624
16t² = 4,624
t² = 4,624/16
t² =289
t = 17
So, 17 seconds to hit the ground
Hence, the piece of wood 17 seconds takes to hit the ground.

In a right triangle the measure of one acute angle is 4 times the difference of the measure of the other acute angle and 5. Find the measure of each acute angle
Answer:
The measures are 22 and 68 degrees
Step-by-step explanation:
for a right triangle, the total angle measure gives 90
Let one of the acute angle be x and the other be y
The measure of one of the acute angle is 4 times the the difference of the measure of the other angle and 5
x = 4(y-5)
Also x + y = 90
Put i into ii
4(y-5) + y = 90
4y-20 + y = 90
5y-20 = 90
5y = 90 + 20
5y = 110
y = 110/5
y = 22
But;
x = 4(y-5)
x = 4(22-5)
x = 4(17)
x = 68
The sum of the acute angles in a right-angled triangle is 90.
The acute angles are 22 and 68 degrees
Let the acute angles be x and y, such that:
[tex]\mathbf{y = 4(x - 5)}[/tex]
So, we have:
[tex]\mathbf{x + y = 90}[/tex]
Substitute 4(x - 5) for y
[tex]\mathbf{x + 4(x - 5) = 90}[/tex]
Open brackets
[tex]\mathbf{x + 4x - 20 = 90}[/tex]
Add x and 4x
[tex]\mathbf{5x - 20 = 90}[/tex]
Add 20 to both sides
[tex]\mathbf{5x = 110}[/tex]
Divide both sides by 5
[tex]\mathbf{x = 22}[/tex]
Recall that:
[tex]\mathbf{y = 4(x - 5)}[/tex]
So, we have:
[tex]\mathbf{y = 4(22 - 5)}[/tex]
[tex]\mathbf{y = 68}[/tex]
Hence, the acute angles are 22 and 68 degrees

The chef at LaBerge started the week with 50 pounds of cheese and used 15 4/5 pounds. How much cheese
remains in inventory?
Answer: 34.2 pounds
Step-by-step explanation:
First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer.

The sum of deviation of a certain number of items measured from 2.5 is 50 and from 5.5 is - 250.Find the arthmetic mean
Answer = 3100
Answer:
3
Step-by-step explanation:
Given that :
A1 = 2.5 ; Σdx1 = 50
A2 = 5.5 ; Σdx2 = -250
Mean (m) = A + Σdx/N = 50
m = A + Σdx/N
m - A = Σdx/N
Nm - NA = Σdx
From the parameters given :
Nm - 2.5N = 50 - - - (1)
Nm - 5.5N = - 250 - - - (2)
Subtract (1) from (2)
3N = 300
N = 300/3
N = 100
Put N = 100 in either (1) or (2)
From (2):
100(m) - 5.5(100) = - 250
100m - 550 = - 250
100m = - 250 + 550
100m = 300
m = 300/100
m = 3
Hence, Arithmetic mean = 3

Answer: k = 3
because p - 1 is a factor of the equation
=> at p = 1, p^4 + p² + p - k =0
with p =1, we have: 1 + 1 + 1 - k = 0
⇔ k = 3
Step-by-step explanation:
Answer:
Solution,
since the factor of f(p) = p-1
we know, f(p)= 0
p=1 (from remainder theorem)
now,
f(p) =p^4+p^2+p-k
0= 1^4+1^2+1-k
0= 1+1+1-k
0= 3-k
k=3
Missing Angles in Triangles Worksheet
I need help with everything on this sheet (A-U) please and thank you.
Answer:
Step-by-step explanation:
This question is based on the angles of the triangle.Therefore, the angles of the triangle is 180 degree.
We need to determined the all the angles of triangle in the figure.
In the triangle ABC,
All sides are equal, therefore it is equivalent triangle. Hence, all angles are also equal.
Therefore, angle A = 60 degree, angle B = 60 degree, angle C = 60 degree.
Now, find the angle N.
In triangle PAN, one of the angle is 69 degree, and the other is 90 degree.
We know that,
Sum of angles of the triangle is 180 degree.
Thus, angle N = 180-69-90
Angle N = 21 degree
From the figure, it is observe that,
Angle P = 90 -69 = 21 degreeAngle O = 90 - angle N = 90 - 21 = 69 degree.Angle R = 90 degree - 15 = 75 degreeAngle Q = 90- 15 = 75 degreeAngle S = 90 - 48 = 42 degreeAngle T = 180- 48-90 = 42 degreeAngle J = 180 - 75 - 90 = 15 degreeAngle L = 180 - 15 - 90 = 75 degreeAngle H = 180 - 75- 60 = 45 degreeAngle I = 90 - 45 = 45 degreeAngle M = 180 - 60 = 120 degreeAngle K = 180 - 120 - 45 = 15 degreeAngle E = 90 - 55 =35 degreeAngle G= 180 - 35 - 90 =55 degreeAngle F = 90 - 55 = 35 degreeAngle U = 69 degree ( from the figure)Angle D = 180 - 69 - 69 = 42 degreeTherefore, these are the all the angles of the given figure.

Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei, iar 3 kg de nectarine şi 9 kg de piersici costă 54 de lei, află cât costă un kilogram de nectarine şi cât costă un kilogram de piersici.
Answer:
Costul unui kilogram de nectarine = x = 6 lei
Costul kilogram de piersicilor = y = 4 lei
Step-by-step explanation:
Lăsa
Costul nectarinelor = x
Costul piersicilor = y
Prin urmare:
Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei
4x + 6y = 48 .... Ecuația 1
3 kg de nectarine și 9 kg de piersici costă 54 de lei
3x + 9y = 54 .... Ecuația 2
Combinând ambele ecuații
4x + 6y = 48 .... Ecuația 1
3x + 9y = 54 .... Ecuația 2
Rezolvăm folosind metoda Eliminare
Înmulțiți ecuația 1 cu 3 și ecuația 2 cu 4 pentru a elimina x
12x + 18y = 144 .... Ecuația 3
12x + 36y = 216 ... Ecuația 4
Scădeți ecuația 4 din 3
-18y = -72
y = -72 / -18
y = 4 lei
Pentru a rezolva pentru x: y = 4
4x + 6y = 48 .... Ecuația 1
4x + 6 × 4 = 48.
4x + 24 = 48
4x = 48 - 24.
4x = 24
x = 24/4
x = 6 lei
Prin urmare:
Costul unui kilogram de nectarine = x = 6 lei
Costul kilogram de piersicilor = y = 4 lei
