Answer: 0.75 hours which is the same as 45 minutes
===========================================================
Explanation:
d = distancer = rate, which is another term for speedt = timeWe're told that the plane flies 375 miles and the speed is 500 miles per hour (mph).
This must mean that d = 375 and r = 500. Let's find t
d = r*t
d/r = t .... divide both sides by r
t = d/r
t = 375/500
t = 0.75
It takes 0.75 hours, which is the same as 45 minutes because
0.75*60 = 45
If the plane flew 500 miles and its speed was 500 mph, then it would take 1 hour, so it makes sense that the plane's time was under an hour if it only traveled 375 miles.

Answer:
1. 12 2. 12 3.1/8 4. 11 5. -15 6.-60 7.20 8.225
Step-by-step explanation:
Given that :
m=2 and n=16 , p = {1-6 =-5} then;
1. m+10 = 2+10 = 12
2. n-4 = 16-4 = 12
3. m / n = 2/16 = 1/8
4. 6m - 1 = 6*2 - 1 = 12 -1 = 11
5. 3p =3* -5 = -15
6.12 p = 12* -5 = -60
7. 12m-4 = 12*2 - 4 = 24 -4 =20
8. 9p² = 9*-5² = 9 * 25 = 225
Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.
Answer:
41.25 ft^2
Step-by-step explanation:
Literally all you need to do is Pythagorean Theroem.
a = ?
b = 11ft
c = 8ft
a^2 + b^2 = c^2
a^2 + 11^2 = 8^2
a^2 + 121 = 64
64 - 121 = a^2
a = 7.5
Then area of a triangle formula is (bh)/2
(11 x 7.5)/2 = 41.25

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?
Answer:
7
Step-by-step explanation:
6,300 divide by 900 would equal 7
Answer:
7 beams
Step-by-step explanation:
To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:
6,300 ÷ 900 = 7
So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

AB is parallel to CD
Find the value of X
Find the value of Y
Answer:
∠y° = ∠69°
∠x = ∠69°
Step-by-step explanation:
1) The question relates to parallel line theorem
The given parameters are;
AB is parallel to CD
∠111° and ∠y° are consecutive interior angles
∠69° and ∠x° are alternate interior angles
When two parallel lines are crossed by a common transversal, the consecutive interior angles are supplementary (sum up to 180°), and the alternate interior angles are equal
Therefore, we have;
∠111° + ∠y° = 180°
∠y° = 180° - ∠111° = ∠69°
∠y° = ∠69°
2) For the alternate interior angles, ∠69° and ∠x°, we have;
Alternate angles are equal, therefore ∠x = ∠69°

What is the apparent solution to the system of equations?
y = -2 +2
y=40 +7
Graph the system of equations using the Line tool. Plot a point at the apparent solution to the system using the point tool.
Answer:
y=−x+2y=4x+7 NO
y=−x+2 YES
y=4x+7
Multiply the first equation by 4, obtaining: 4y = -4x + 8
Add the 2nd equation to this result: y = 4x + 7
--------------------
5y = 15, and y = 3
Then, using the first equation, determine x:
y = 3 = -x + 2
1 = -x, so x = -1
The solution is (-1, 3)
Answer: (-1; 3)
Step-by-step explanation:
y = -x + 2
y = 4x + 7
4x + 7 = -x + 2
4x + 7 + x - 7 = - x + 2 + x - 7
5x = - 5
x = - 1
y = 4(-1) + 7
y = 3
Intersection point: (-1; 3)

Step-by-step explanation:
Answer:
15.51
Step-by-step explanation:
The calculator is $49.50.
The radio is $114.99.
First, we add them together.
49.50+114.99 = 164.49
that is the total cost of both the radio and calculator.
Next, we subrtact 180.00-164.49= 15.51.

Step-by-step explanation:
use the chain rule to calculate y = (2u² + 3)⅓ and u = √(2x +1)
full method
Answer:
Given the reference to the chain rule, I assuming by "calculate", you mean "take the derivative of", in which case we have:
For the first function:
[tex]y = (2u^2 + 3)^{\frac{1}{3}}\\\\\frac{dy}{du} = \frac{1}{3}(2u^2 + 3)^\frac{-2}{3}(4u)\\\\\frac{dy}{du} = \frac{4u}{3}(2u^2 + 3)^\frac{-2}{3}\\\\\frac{dy}{du} = \frac{4u}{3(2u^2 + 3)^\frac{2}{3}}[/tex]
and for the second one:
[tex]u = \sqrt{2x + 1}\\\\u = (2x + 1)^{0.5}\\\\\frac{du}{dx} = 0.5(2x + 1)^{-0.5}(2)\\\\\frac{du}{dx} = \frac{1}{\sqrt{2x + 1}}[/tex]

Answer:
48
Step-by-step explanation:
4x=148+44
4x=192
x=48
Answer:
Step-by-step explanation:
there are 360 degrees inside any 4-sided polygon
so add all four angle measures and set equal to 360:
3x + x + 44 + 148 = 360
4x + 192 = 360
4x = 168
x = 42
check:
3(42) + 42 + 44 + 148 should equal 360
126 + 42 + 192 = 360
168 + 192 = 360
360 = 360
A builder needed to buy one hundred fifty-four boards for his latest project. If the board he needs comes in packs of three, how many packets will he need to buy
Answer:
51.3 packets or 51 1/3 packers
Step-by-step explanation:
From the above question:
The board he needs comes in packs of three. This means
1 pack = 3 boards
Hence:
3 boards = 1 packet
154 boards = x
Cross Multiply
3x = 154
x = 154/3
x = 51.333333333 packets
Approximately = 51.3 packets or 51 1/3 packers
The builder will need to buy 51.3 packets or 51 1/3 packers

90-59= 31
31+90+59 = 180
Answer:
[tex]x=31^{\circ},\\y=5[/tex]
Step-by-step explanation:
Since DB bisects [tex]\angle ABC[/tex], [tex]DC=DA[/tex]. Therefore, [tex]\fbox{$y=5$}[/tex].
From the isosceles base theorem, the measure of the angles adjacent to the congruent sides of an isosceles triangle are equal. Therefore, we can write the following equation:
[tex]2x+59+59=180,\\2x+118=180,\\2x=62,\\x=\fbox{$31^{\circ}$}[/tex].

Tres maquinas (A,B,C) producen el 40 % , 35% y 25 % respectivamente , del total de las piezas manufacturadas en una fabrica .Los porcentajes de produccion defectuosa de estas maquinas son del 3% 4 % y 5 % respectivamente
Answer:
La probabilidad de que la pieza elegida sea defectuosa, P(D), 0.0385
La máquina con mayor probabilidad de haber producido la pieza defectuosa es A
Step-by-step explanation:
Sea D= "la pieza es defectuosa" y N= "la pieza no es defectuosa". La información del problema puede expresarse en el diagrama de árbol adjunto.
Para calcular la probabilidad de que la pieza elegida sea defectuosa, P(D), por la propiedad de la probabilidad total,
P(D) = P(A) · P(D/A) + P(B) · P(D/B) + P(C) · P(D/C) =
= 0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05 = 0.0385
Debemos calcular P(B/D). Por el teorema de Bayes,
P(B/D)= P(B) x P(D/B) / P(A) x P(D/A) + P(B) x P(D/B) +P(C) x P(D/C)
= 0.35 · 0.04 / 0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05
Calculamos P(A/D) y P(C/D), comparándolas con el valor de P(B/D) ya calculado. Aplicando el teorema de Bayes, obtenemos:
0.012
0.0385
P(A/D)= 0.311
0.014
0.0385
P(B(D)=0.363
0.0125
0.0385
P(C/D)=0.324
La máquina con mayor probabilidad de haber producido la pieza defectuosa es A
