Answer:

Angle addition postulate and 2x=56

Step-by-step explanation:

The value of x is 28 degree.

Linear pair of angles are formed when two lines intersect each other at a single point.

Given:

m∠ELG = 124

as, m∠ELG and m∠ELD are in linear pair.

So, 124 + 2x =180

2x =56

x -28

Hence, the value of x is 28 degree

Answer:

The measure of angle LMW is [tex]m\angle LMW=67\°[/tex]

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc MW

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m\angle MLK=\frac{1}{2}[arc\ MW+arc\ WK][/tex]

substitute the given values

[tex]65\°=\frac{1}{2}[arc\ MW+68\°][/tex]

[tex]130\°=[arc\ MW+68\°][/tex]

[tex]arc\ MW=130\°-68\°=62\°[/tex]

step 2

Find the measure of arc LK

we know that

[tex]arc\ LM+arc\ MW+arc\ WK+arc\ LK=360\°[/tex] -----> by complete circle

substitute the given values

[tex]164\°+62\°+68\°+arc\ LK=360\°[/tex]

[tex]294\°+arc\ LK=360\°[/tex]

[tex]arc\ LK=360\°-294\°=66\°[/tex]

step 3

Find the measure of angle LMW

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m\angle LMW=\frac{1}{2}[arc\ LK+arc\ WK][/tex]

substitute the given values

[tex]m\angle LMW=\frac{1}{2}[66\°+68\°]=67\°[/tex]

Applying the inscribed angle theorem, the measure of angle LMW is found as: 67°.

According to the inscribed angle theorem, the measure of an inscribed angle is half the measure of the arc that is intercepted.

Given:

Find m(MK):

m(MK) = 2(m∠MLK) (inscribed angle theorem)

Substitute

m(MK) = 2(65°)

m(MK) = 130°

Find m(LK):

m(LK) = 360° - m(LM) - m(MK) (full circle)

Substitute

m(LK) = 360° - 164° - 130°

m(LK) = 66°

Therefore:

m∠LMW = 1/2[m(LK) + m(WK) (inscribed angle theorem)

Substitute

m∠LMW = 1/2[66° + 68°]

m∠LMW = 1/2[134°]

m∠LMW = 67°

EXPLANATION

The area of a kite is half the product of the diagonals.

The first diagonal is

9m+6m=15m

Note that the vertical diagonal is the axis of symmetry of the kite.

This diagonal bisect the kite

Therefore the second diagonal is

2(9m)=18m

The area of the kite

[tex] = \frac{1}{2} \times 18 \times 15[/tex]

[tex] = 9 \times 15[/tex]

[tex] = 135 {m}^{2} [/tex]

Answer:

Step-by-step explanation:

Hello

To solve this problem we can divide the kite into simpler geometric figures to find its area, we have four triangles

the area of a triangle =(b*h)/2

b is the base and his the heigth

Answer:

[tex]x+y>0[/tex]

[tex]x-y\leq 0[/tex]

Step-by-step explanation:

Given that the sum of x and y is greater than 0.

So we can write inequality [tex]x+y>0[/tex].

When y is subtracted from x, the difference is less than or equal to 0.

So the next inequality is [tex]x-y\leq 0[/tex].

Hence required system of inequalities that can be used to  solve for x and y is :

b) 904.78in³

Step-by-step explanation:

a) The formula to find the volume of a cylinder is:

[tex]V = \pi r^2h[/tex]

We are given that r = 5 and h = 3, so we can just plug in and solve:

We are given that the diameter is 12in, which means that the radius (r) must be 6in (half the diameter). Now, we can plug in and solve:

[tex]V = \frac{4}{3}\pi (6)^3 = 904.78in^3[/tex]

Answer:

Step-by-step explanation:

Each term is 6 less than the past term. Hopw this helps!

There is no "standard" way to solve an exercise like this: you just have to eyeball the sequence and try to find/guess the pattern.

The most common (and easy!) examples are arithmetic or geometric sequence, where the difference or ratio between two consecutive terms is constant.

This is one of those cases: this is an arithmetic sequence, because you obtain every next term by subtracting 6 from the previous one:

[tex]a_1 = 7\\a_2 = a_1-6 = 7-6 = 1\\a_3 = a_2-6 = 1-6 = -5\\a_4 = a_3-6 = -5-6 = -11\\a_5 = a_4-6 = -11-6 = -17[/tex]

So, we can deduce

[tex]a_6 = a_5-6 = -17-6 = -23[/tex]

Answer:

Degree: 5

Y-intercept: 12

Step-by-step explanation:

The given expression is

[tex]f(x)=-(x+1)^2(2x-3)(x+2)^2[/tex]

Since the factors are multiplying, we can analyse the degree of each factor and add them to find the degree of the polynomial.

The degree of the factor [tex]-(x+1)^2[/tex] is 2.

The degree of [tex](2x-3)[/tex] is 1

The degree of [tex](x+2)^2[/tex] is 2

Therefore the degree of the polynomial is 2+1+2=5

To find the y-intercept, we put x=0.

[tex]f(0)=-(0+1)^2(2(0)-3)(0+2)^2[/tex]

[tex]f(0)=-(-3)(4)=12[/tex]

The y-intercept is 12

Answer: X = 8 And Y = 5 "First Choice Letter A"

Step-by-step explanation: x + y = 13......x = 13 - y

2x - 3y = 1

2(13 - y) - 3y = 1

Answer: -30

I really hope this helped you

To solve 3 3/5 x (-8 1/3), we convert the mixed numbers into improper fractions, multiply them, and simplify to get the answer -30.

The student is asking to perform multiplication between a mixed number and a mixed number with a negative sign. To compute 3 3/5 x (-8 1/3), we first convert the mixed numbers into improper fractions. The number 3 3/5 can be converted to 18/5 (since 3*5 + 3 = 18) and -8 1/3 can be converted to -25/3 (since -8*3 + 1 = -25). Multiplying these two improper fractions gives us (18/5) * (-25/3). To multiply fractions, we multiply the numerators together and the denominators together, giving us -450/15. Simplifying this fraction, we get the final answer, which is -30.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) The cost of a pound of green grapes is,

Y = 1.5X = 1.5×3 = 4.5

Hence, the first statement is false.

B.) The cost of a pound of green grapes is $1.5, while the cost of a pound of black grapes is $2. Thus, the second statement is false.

C.) The cost of a pound of green grapes is $1.5, while the cost of a pound of black grapes is $2. Thus, the third statement is true.

D.) As per the graph, the cost of 2 pounds of grapes is $4. Thus, the fourth statement is wrong.

Answer:

1/26

Step-by-step explanation:

There's only 1 four of spades and only 1 six of diamonds.  So the probability is:

P = P(4 of spades) + P(six of diamonds)

P = 1/52 + 1/52

P = 1/26

The probability of selecting the four of spades or the six of diamonds from a standard 52-card deck is 1/26. This is determined by adding the probabilities of each individual card being drawn since they are mutually exclusive events.

The question asks about the probability of selecting a specific card from a standard 52-card deck. To find the probability of selecting either the four of spades or the six of diamonds, we recognize that these are two distinct events. Since there is one four of spades and one six of diamonds in a deck, and there are 52 cards in total, the probability of drawing the four of spades is 1/52 and similarly the probability of drawing the six of diamonds is also 1/52. These events are mutually exclusive, meaning they cannot happen at the same time, so we can simply add the two probabilities together to find the total probability:

Probability(four of spades or six of diamonds) = Probability(four of spades) + Probability(six of diamonds) = 1/52 + 1/52 = 2/52.

Therefore, the probability is 2/52, which can be simplified to 1/26.
