Answer:
GCF of the numbers is 3 and it can be written as 3(1+5)
Step-by-step explanation:
Given the expression 3+15
First we need to find their factors
3 = 3×1
15 = 3×5
Since 3 is common to both factors, hence the GCF is 3
Factorize
3+15
= (3×1)+(3×5)
Factoring 3 out
= 3(1+5)
Hence the GCF of the numbers is 3 and it can be written as 3(1+5)
if in a triangle ac= 15 and angle abc=60 degrees what is ab?
Answer:
∠A=30° and AC and BC is 13 and 7.5 units respectively
Step-by-step explanation:
Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units
we have to find the remaining angles.
By angle sum property, sum of angles in right angle is 180°
∠A+∠B+∠C=180°
∠A+ 60°+90°=180
∠A=180°-150°=30°
∠A=30°
As AB= 15
Now by trigonometric ratios we find the other sides of triangle ABC
Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

Can someone please help me on this homework ASAP!!
Answer:
Step-by-step explanation:
Multiply each term of (x² + 2x - 1) by x and multiply each term of (x² + 2x - 1) by 3
Area of parallelogram = bh
= (x² + 2x - 1)(x + 3)
= (x² + 2x - 1)*x + (x² + 2x - 1)*3
=x²*x + 2x*x - 1*x + x²*3 +2x*3 - 1*3
= x³ + 2x² - x + 3x² + 6x - 3
= x³ + 2x² + 3x² -x + 6x - 3
= x³ + 5x² + 5x - 3

Answer:
y = -2/3x + 8
Step-by-step explanation:
Format: y = mx + b
m = slope (rise over run) - 2/3 The graph is negative so the slope is also negative.
b = y - intercept (8)
Without properly working spark plugs, a vehicle will not run. For a specific vehicle, the spark plugs are supposed to have a gap between 3.9mm and 4.3mm. Any spark plugs with gaps larger or smaller than this will fail inspection and be discarded. At the factory, the machine that sets the gap follows a normal distribution with a mean of 4.1mm and standard deviation of 0.075mm. What is the probability that a randomly selected spark plug passes inspection
Answer:
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922
Step-by-step explanation:
Step(i):-
Given that the mean of the Normal distribution = 4.1mm
Given that the standard deviation of the Normal distribution = 0.0075mm
Let 'X' be the random variable in a normal distribution
Given that X₁ = 3.9mm
[tex]Z_{1} = \frac{X_{1} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{3.9 -4.1}{0.075} = -2.666[/tex]
Given that X₂ = 4.3mm
[tex]Z_{2} = \frac{X_{2} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{4.3 -4.1}{0.075} = 2.666[/tex]
Step(ii):-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = P(-2.666≤Z≤2.666)
= P(Z≤2.666)-P(Z≤-2.666)
= 0.5 +A(2.666) - (0.5-A(2.666)
= 2 × A(2.666)
= 2×0.4961
= 0.9922
Final answer:-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922

A person is standing 215 feet above the ocean
watching a ship come in. Initially the angle of elevation
from the boat to the person is 31 degrees. After
traveling towards the person for a few minutes, then
angle is 48 degrees. How far did the boat travel
between the two points? Round to the nearest foot.
Answer:
Step-by-step explanation: I don’t know I just want my extra points
Answer: 164 ft
Step-by-step explanation:
tan 48=215/x
-> x.tan48=215
->x =215/tan 48
->x = 193.6
tan 31=215/y
-> y.tan31 = 215
-> y= 215/ tan 31
-> y= 357.82
BC= y-x
= 357.82-193.6
= 164.22 = 164 ft

Which two quadrilaterals are reflections of each other across the y-axis?
Answer:
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Step-by-step explanation:
Can we make a triangle out of one angle that measure 20 degrees and another that measures 45 degrees
Answer:
Yes. If the third angle is equal to 115 degrees.
Step-by-step explanation:
The sum of all the angles in a triangle must equal 180 degrees.
If the two angles are 20 degrees and 45 degrees the third angle must be
180-45-20= 115 degrees
A triangle having three different angles is called a scalene triangle.
A scalene triangle also has three different sides.
But if the third angle is less or greater than 115 degrees the triangle cannot be formed.
This is the called the sum property of triangle.
There is another property which must also be satisfied i.e the sum of any 2 sides must be greater than the third side.
