Is there a triangle whose sides have lengths 12.2 cm, 6.8 cm and 6.5 cm. If not . Why?

Answer:

Yes

Step-by-step explanation:

Answer:

Option A. x = 8

Step-by-step explanation:

Please see attached photo.

From the attached photo,

we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:

(√80)² = 8² + y²

80 = 64 + y²

Collect like terms

80 – 64 = y²

16 = y²

Take the square root of both side

y = √16

y = 4

Finally, we shall determine the value of x. This can be obtained as follow:

From the attached photo,

x = 2y

but:

y = 4

Therefore,

x = 2y

x = 2 × 4

x = 8

Answer:

y = 36

Step-by-step explanation:

[tex]\frac{y}{3}+2 = 14\\\\\frac{y}{3}=14-2\\\\\frac{y}{3}=12\\\\y = 12*3\\\\y = 36[/tex]

Answer:

86

Step-by-step explanation:

Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.

<L is opposite to side JK, <J is opposite to side KL.

m<J is given as 47°. Therefore,

m<L = m<J = 47°

m<L = 47°

m<J + m<L + m<K = 180° (sum of triangle)

47° + 47° + m<K = 180° (substitution)

94° + m<K = 180°

m<K = 180° - 94°

m<K = 86°

Answer:

It is between A and D, all the problem is about predictions and how this predictions are tricked.

Step-by-step explanation: Just make some draws of the number and colors of the marbles, and add the white marbles to the red ones, there is 6 of them, they take out of the bag two, so there are still being four, a hundred is all a number (?) so divided 100 % in 4/ there is 25, is D just take D. Sorry man im tired.

hi..

let total amount of money Darius's parents sent to the book fair is m then according to the question

m= 4 × $11.50

m= $46

So Darius parents sent $46 to the book fair to be split among 4 children in his family..

hope it helps:)

Byehave fun k bye

Answer:

29.4%

Step-by-step explanation:

the whole cirlce is 360 degrees which means 100%

to find the percentage of the shaded area, multiply the degrees by 100

⇒ 10.6 x 100 = 10600

then take the product and divide by 360

⇒ 1060 ÷ 360

⇒ 29.44

round to the nearet tenth of a percent

⇒ 29.4

The partial sum of the geometric series is;

⇒ 125 + 25 + 5 + 1

Option A is true.

What is Geometric series?

Geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.

Given that;

The geometric series.

∑ 125 (1/5)ⁿ⁻¹ ; where, n = 1 to 4.

Now, Calculate the partial sum of the geometric series as;

The geometric series = ∑ 125 (1/5)ⁿ⁻¹

Substitute n = 1, 2, 3, 4, we get;

= 125 (1/5)¹⁻¹ + 125 (1/5)²⁻¹ + 125 (1/5)³⁻¹ + 125 (1/5)⁴⁻¹

= 125 (1/5)⁰ + 125 (1/5)¹ + 125 (1/5)² + 125 (1/5)³

= 125 + 25 + 125/25 + 125/125

= 125 + 25 + 5 + 1

Thus, The partial sum of the geometric series is;

⇒ 125 + 25 + 5 + 1

Option A is true.

Answer:

$159.75

Step-by-step explanation:

137.45/252.60 + x = 1/3

252.60 + x = 412.35

x = 412.35 - 252.60

x = 159.75

5x = 15

/5     /5

x = 3

Answer:

x=3

Step-by-step explanation:

5x+1/4=61/4

5x=61/4-1/4(61/4-1/4, they have the same denominator so can subtract them with each other)

5x=60/4   (60/4=15)

5x=15

x=15/5

x=3

Tip :to check your answer simply plug in the  value and then solve the equation. If both the sides are equal to each other, the answer is most likely correct.

Answer:

(3, 1.7)

Step-by-step explanation:

The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.

Two lines are perpendicular if the product of their slopes is -1.

The slope of the line joining D(0,0), F(3,7) is:

[tex]m_1=\frac{7-0}{3-0}=\frac{7}{3}[/tex]

The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)[/tex]

The slope of the line joining E(7,0), and F(3,7). is:

[tex]m_1=\frac{7-0}{3-7}=-\frac{7}{4}[/tex]

The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:

[tex]y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)[/tex]

The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:

x = 3, y = 1.7

Answer:

choice 2) angle DOC = 145 degrees

Step-by-step explanation:

angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.

angle AOB = 180 - 20 - 15 = 145 degrees

angle DOC  = angle AOB because it is a vertical angle to 145 degrees.

Answer:

Answer:

30.

Step-by-step explanation:

first term = a

3r term = ar^2

So here ar^2/ a  = r^2

r^2 = 5/180 = 1/36

r = 1/6

So missing term = 180 * 1/6 = 30.
