Latifah drew this obtuse, scalene triangle.
A triangle has side lengths 8 and 10. The angle between the 2 sides has a measure of 116 degrees.
She will draw a congruent triangle and use it to form a 4-sided polygon. What type of quadrilateral could it be?
a quadrilateral that is a parallelogram
a rectangle that is not a rhombus
a rhombus
a square
Answer:
i'd say its a rhombus (C)
Step-by-step explanation:
i have this question on my exam on edg. and that is the answer i came up with after reviewing the image that was provided on the exam.
other people say that its a quadrillateral that is a parallelogram but i drew out the shape and the lines were intersecting. so its probably not A. :)

square root of 225/16 AS A FRACTION!!!
The solution is, square root of 225/16 is 15/4.
What is Square root?A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.
For example, 4 and −4 are square roots of 16, because 4² = ² = 16.
here, we have,
225/16
=15^2/4^2
so, square root of 225/16
=√15^2/4^2
=15/4
Hence, The solution is, square root of 225/16 is 15/4.

Fill in the missing number. 7 + __ = 88
Answer:
[81 is the missing number.]
Step-by-step explanation:
7+x=88
Let us substitute the mixing number as x.
To find a variable we must ISOLATE it.
To isolate in this situation, we must remove the 7.
We must subtract 7 from both sides, to isolate x. like this-
7-7+x=88-7
This results in,
x=81
So this missing number or (x) is equal to 81

Which scenario will produce light?
a) an electron moving into the nucleus
b) an electron is removed from the atom
c) an electron moving to a ground state
d) an electron moving to an excited state
Answer:
an electron moving into the nucleus
When an electron moved to an excited state, it will produce light. So, the correct option is (D).
What is Light?
Light are commonly referred as Electromagnetic Radiation which can be detected by the human eye. This spectrum is extremely broad which ranges from low energy radio waves with wavelengths that are to high energy gamma rays with wavelengths which are less than 1x [tex]10^-^1^1[/tex].
The largest electromagnetic waves having wavelengths from a few centimeters to over 100 meters called as radio waves while the smallest electromagnetic waves having wavelengths which is the size of an atomic nucleus are called gamma rays. In between these waves, microwaves, infrared light, visible light, ultraviolet light and X-rays. It refers to visible radiant energy.
Light is emitted when an electron jumps from a higher orbit to a lower orbit and absorbed when it jumps from a lower to higher orbit which causes to produce light.
Thus, when an electron moved to an excited state, it will produce light. So, the correct option is (D).

If angle a has the terminal ray that falls in the fourth quadrant and cosine a equals 5/9 then determine the value of sin a in simplest radical form
Answer: [tex]-\dfrac{2\sqrt{14}}{9}[/tex]
Step-by-step explanation:
Given
[tex]\cos a=\dfrac{5}{9}[/tex]
[tex]a[/tex] lies in the fourth quadrant
So, sine must be negative in the fourth quadrant
Using identity [tex]\sin ^2 x+\cos^2 x=1[/tex] to find sine value
[tex]\Rightarrow \sin^2 a=1-\dfrac{5^2}{9^2}[/tex]
[tex]\\\\\Rightarrow \sin^2 a=1-\dfrac{25}{81}\\\\\\\Rightarrow \sin^2 a=\dfrac{56}{81}\\\\\\\Rightarrow \sin a=-\sqrt{\dfrac{56}{81}}\\\\\\\Rightarrow \sin a=-\dfrac{2\sqrt{14}}{9}[/tex]

For each given sequence: write down term to term rule and position to term rules 2,5,8,11,14
Answer:
Tn = 3n + 1
Step-by-step explanation:
The given sequence 2,5,8,11,14 is an arithmetic sequence
The nth term of an arithmetic sequence is expressed as;
Tn = a + (n-1)d
a is the first term
d is the common difference
n is the number of terms
Given
a = 2
d = 5-2 = 8-5 = 3
Substitute into the formula
Tn = 2 + (n-1) * 3
Tn = 2 + 3n - 3
Tn = 3n + 1
This gives the term rule for the sequence
Josefina lives near a duck pond. She wants to know how many ducks use the pond. She places leg bands on 12 ducks one day. A week later, she examines 20 ducks and finds that 3 of them have leg bands. About how many ducks use the pond? 80 29 160 50
Answer:
80
Step-by-step explanation:
This is calculated as:
(Number of ducks with bands × Number of examined ducks)/ Number of ducks found with leg band
= Number of ducks with bands = 12 ducks
Number of examined ducks = 20 ducks
Number of ducks found with leg band = 3 ducks
Hence:
12 × 20/3
= 240/3
= 80 ducks
Therefore, 80 ducks used the ponds
Line m is represented by the equation y + 2 = 3/2(x + 4). Select all equations that
represent lines perpendicular to line m.
A. y = -3/2x +4
B. y = -2/3x +4
C. y = 2/3x +4
D. y = 3/2x +4
E.y+1=-4/6(x+5)
F.y+ 1 = 3/2(x + 5)
The equations representing the lines that are perpendicular to line m are:
B. y = -2/3x +4
E. y+1=-4/6(x+5)
What is the Slope of Perpendicular Lines?Lines that are perpendicular to each other have slopes that are negative reciprocal of each other.
For example, if a line has a slope of 2, the slope of a line that is perpendicular to it would be, -1/2 (negative reciprocal of 2).
Determine the slope of the given line whose equation is, y + 2 = 3/2(x + 4). Rewrite the equation in slope-intercept form [y = mx + b]:
y + 2 = 3/2x + 6
y = 3/2x + 6 - 2
y = 3/2x + 4
The slope is therefore 3/2.
Negative reciprocal of 3/2 is -2/3.
Examine each of the equations given and see which equation has a slope of -2/3.
A. y = -3/2x +4, the slope is -3/2.
B. y = -2/3x + 4, the slope is -2/3. (perpendicular)
C. y = 2/3x +4, the slope is 2/3.
D. y = 3/2x +4, the slope is 3/2.
E. y+1=-4/6(x+5), rewrite in slope-intercept form
y+1=-4/6x + 20/6
y + 1 = -2/3x + 10/3
The slope is -2/3. (perpendicular)
F. y+ 1 = 3/2(x + 5), the slope is 3/2.
Therefore, the equations representing the lines that are perpendicular to line m are:
B. y = -2/3x +4
E. y+1=-4/6(x+5)

Step-by-step explanation:
Zina goes shopping. She buys in the same store two scarves and three T-shirts for
49 euros. A week later, it was the sales: reduction of 1.5 euros on scarves and 2 euros
on t-shirts. Zina took the opportunity and for 40 euros, she was able to buy four scarves and five T-shirts.
What was the price of a scarf and a T-shirt before the sales?
THX FOR HELPING!
Answer:
The price of T-shirts before the sale = 42 euros
The price of scarves before the sale = -77/2 euros
Step-by-step explanation:
The cost of the items Zina buys from the store initially are;
Two scarves and three T-shirts for 49 euros
The reduction in the price of scarves a week later during sales = 1.5 euros
The reduction in the price of T-shirts a week later during sales = 2 euros
The items Zina bought for 40 euros at the reduced price of the sales opportunity are;
Four scarves and five T-shirts for 40 euros
Let 'x' represent the initial price of a scarf and let 'y' represent the initial price of a T-shirt, we have;
2·x + 3·y = 49...(1)
4·(x - 1.5) + 5·(y - 2) = 40...(2)
Expanding equation (2) gives;
4·x - 6 + 5·y - 10 = 40
4·x + 5·y = 40 + 6 + 10 = 56
∴ 4·x + 5·y = 56...(3)
By multiplying equation (1) by 2 and subtracting the result from equation (3), we get;
4·x + 5·y - 2 × (2·x + 3·y) = 56 - 2 × 49 = -63
-y = -42
y = 42
The price of T-shirts before the sale = 42 euros
x = (49 - 3 × 42)/2 = -77/2
x = -77/2
The price of scarves before the sale = -77/2 euros
(However, if the had bought the 4 scarves and 5 T-shirts during sales at 70 euros, we get;
The price of T-shirts before the sale = 12 euros
The price of scarves before the sale = 6.5 euros.
The allowable total price for the reduced 4 scarves and 5 T-shirts is between 66 and about 82 for both initial prices to be +ve)
Find the value for x
Answer:
Value of x --> 15°
Step-by-step explanation:
(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.
---> (2x + 60°) + 6x = 180°
2x + 60° + 6x = 180°
8x + 60° = 180°
8x = 180°- 60°
8x = 120
x = [tex]\frac{120}{8}[/tex]
x equals 15°sketch 0=7pi/6 in standard position
