math question pls help me
Answer:
A. 45°
Step-by-step explanation:
The sum of all the angles in a quadrilateral must be 360. This means that you need to subtract 135, 90, and 90 from 360 to get the unknown angle.
360 - 90 - 90 - 135 = 45°

Help please and give reasoning
Answer:
d. LK, LJ, JK
Step-by-step explanation:
first, let's compare the values of the angles
m∡J < m∡K<m∡L (because of algebra)
(33°<71°<76°)
side-angle inequality states that the side opposite to the largest angle is the longest side, the side opposite to the 2nd largest angle is the 2nd longest side, and the side opposite to the smallest angle is the shortest side
the side opposite from m∡J (LK) is the shortest, as m∡J has the smallest value (this is because of side-angle inequality)
the side opposite from m∡K (LJ) is the 2nd shortest, as m∡K has the 2nd-smallest value (this is because of side-angle inequality)
the side opposite from m∡L (JK) is the longest, as m∡L has the largest value (because of side angle-inequality)
written as an inequality, the sides from smallest to largest are:
LK<LJ<JK (because of substitution and side-angle inequality)
so listed from shortest to longest:
LK, LJ, JK
therefore the answer is d

A diver found a school of fish 85 feet below the surface of the ocean. He found coral 95 feet deeper than the fish. How many feet deep from the surface was the coral?
Answer:
180 feet
Step-by-step explanation:
85+95=180 because depth + depth.
The total deep 180 feet from the surface was the coral.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that diver found the school of fish 85 feet below the surface of the ocean. Which he found coral 95 feet deeper than the fish.
The total deep from the surface was the coral.
Therefore, it could be;
depth + depth.
85 + 95 = 180
Hence, the total deep 180 feet from the surface was the coral.

A $100 tablet is marked up by 10% and then the new price is marked down by 10%. What is the final price?
Answer:
$99
Step-by-step explanation:
So the initial price of the tablet was $100. It was marked up by 10% and then marked down by 10%. We are asked to find the final price.
To find the final price, lets first find the price after the tablet price was marked up by 10%. This means that the tablet price increased by 10%. To find the price, we can add 10% of the new original price (or 10% times $100) original price ($100):
$100 + ($100 × 0.1) = $100 + $10 = $110
We could have also multiplied $100 by 1.1 (or 1 + 10%) to find the new price.
So now we know that the new price after the tablet is marked up by 10% is $110. Now, to find the final price, we have to find the price after the new price is marked down by 10%. We can do this by taking the new price ($110) and subtracting 10% of the new price (or 10% times $110):
$110 - ($110 × 0.1) = $110 - $11 = $99
So the final price of the tablet would be $99.

I really need help
Answer:
1) v_i = 2.78 m/s
v_f = 16.67 m/s
t = 5 s
Acceleration = 2.78 m/s²
2) a = 1.5 m/s²
Step-by-step explanation:
1) The car was running at 10 km/hr.
In m/s this is 2.78 m/s
Thus;
Initial velocity; v_i = 2.78 m/s
It increased its speed to 60 km/hr in 5 seconds.
Thus, final velocity is 60 km/hr
Converting to m/s gives; 16.67 m/s
Final velocity; v_f = 16.67 m/s
Time to reach final velocity; t = 5 seconds
From Newton's first equation of motion, we can find the acceleration;
a = (v_f - v_i)/t
a = (16.67 - 2.78)/5
a = 2.78 m/s²
2) started from test, so initial velocity;
v_i = 0 m/s
Reached a speed of 9 m/s in 6 seconds.
Final velocity; v_f = 9 m/s
Time; t = 6 s
Acceleration is calculated as;
a = (v_f - v_i)/t
a = (9 - 0)/6
a = 1.5 m/s²

A man measures the angle of elevation between the ground and a building 800ft away to be 30
degrees. How tall is the building?
Answer:
461.88 feet
We are given the opposite and adjacent of 30.
Tan (30) = opposite / adjacent
Tan (30) = x / 800
X = 800 x Tan(30)
X = 461.88
- Use a calculator to calculate "Tan(30)".
- The exact answer is 461.880215
The height of the building will be equal to 461.88 feet.
What is trigonometry?
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

what is the sum of exterior angles of any polygon
Answer:
the sum of all exterior angles equal 360
Step-by-step explanation:
Summed, the exterior angles equal 360 degrees. A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.

Carol has 88cm of string and cuts it in the ratio 5 : 6. How much longer is the
longest piece compared to the shortest piece
Given:
Carol has 88cm of string and cuts it in the ratio 5 : 6.
To find:
How much longer is the longest piece compared to the shortest piece.
Solution:
Let the lengths of two pieces of string are 5x and 6x. Then,
[tex]5x+6x=88[/tex]
[tex]11x=88[/tex]
[tex]x=\dfrac{88}{11}[/tex]
[tex]x=8[/tex]
Now, the lengths of pieces are:
[tex]5x=5(8)[/tex]
[tex]5x=40[/tex]
And,
[tex]6x=6(8)[/tex]
[tex]6x=48[/tex]
The difference between the longer piece and shorter piece is:
[tex]48-40=8[/tex]
Therefore, the longer piece is 8 m longer than the shorter piece.

Answer: [tex]\dfrac{14}{55}, \dfrac{13}{55}[/tex]
Step-by-step explanation:
Given
There are 8 red and 4 blue beads
Three beads were taken from the box
(i)No of ways of choosing three red beads out of 12 beads is [tex]^8C_3[/tex]
Total no of ways [tex]^{12}C_3[/tex]
Probability is
[tex]P=\dfrac{^8C_3}{^{12}C_3}=\dfrac{8\times 7\times 6}{12\times 11\times 10}=\dfrac{2\times 7}{11\times 5}\\P=\dfrac{14}{55}[/tex]
(ii)atleast two beads refers to minimum two beads
There can be two possibilities (2B,1 R), (3B, 0R)
