need help please and thank you?!

Answer: 23.96

first you gotta put in the parenthese in. (6.4/1.6)x 5+( 1.3x3.1)-0.07.

second: do the Equation in the parentheses.

6.4/1.6=4

1.3x3.1=4.03

4x5=20

20+4.03=24.03

24.03-0.07=23.96 final answer

Hope this helps!!

Given:

In a circle, two chords AK and LJ intersect each other inside the circle at M.

Measure of arc AJ = 65 degrees.

Measure of arc KL = 85 degrees.

To find:

The measure of angle KML.

Solution:

Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.

Using Intersecting chords theorem, we get

[tex]m\angle KML =\dfrac{1}{2}(arcKL+arcAJ)[/tex]

[tex]m\angle KML =\dfrac{1}{2}(85^\circ +65^\circ )[/tex]

[tex]m\angle KML =\dfrac{1}{2}(150^\circ )[/tex]

[tex]m\angle KML =75^\circ[/tex]

Therefore, the measure of angle KML is 75 degrees.

Answer:

37 degrees

Step-by-step explanation:

The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees

Answer:

y = 7

NO = 5

Step-by-step explanation:

Let the side of the parallelogram LM and NO given be 2y - 9 and y - 2

Since LMNO is a parallelogram, hence;

LM = NO

2y - 9 = y - 2

2y - y = -2 + 9

y = 7

Since NO = y - 2

NO = 7 - 2

NO = 5

Answer:

y=-17x-25

Step-by-step explanation:

9-9=0

-2-15=-17

(y-9)÷(x+2)= -17

y-9=-17x-34

y= -17x-25

Answer:

124858

Step-by-step explanation:

The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.

6 + 2 + 8

6 * 2 = 12

6 * 8 = 48

Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2

12 + 48 = 60

60 - 2 = 58

Put them together

Answer: 12

Step-by-step explanation: c = √a2 + b2

The length of the slide has a height of 6 feet and the base of 10 feet would be equal to the nearest whole number 12 feet.

The ratio of the height of the slide and the distance from the base of the ladder to the front of the slide is 3 : 5.

The height of the slide is 6 feet.

The base of the ladder is 10 feet.

The Pythagoras is the sum of the square of two sides which is equal to the square of the longest side.

From the Pythagoras Theorem,

[tex]\rm a^{2} =b^{2} +c^{2} \\\rm a^{2} =10^{2} +6^{2} \\\rm a^{2} =100+36\\\rm a = \sqrt{136} \\\rm a = 11.6619\\\rm a=12[/tex]

By round off up to nearest whole number. The length of the slide would be 12 feet.

Given:

Radius of half sphere and cone = 6 cm

Height of cone = 12 cm

To find:

The volume of composite figure that is made up of a cone and a half sphere.

Solution:

Volume of half sphere is:

[tex]V_1=\dfrac{2}{3}\pi r^3[/tex]

Where r is the radius of the half sphere.

Putting [tex]\pi =3.14, r=6[/tex], we get

[tex]V_1=\dfrac{2}{3}(3.14)(6)^3[/tex]

[tex]V_1=\dfrac{6.28}{3}(216)[/tex]

[tex]V_1=452.16[/tex]

Volume of a cone is:

[tex]V_2=\pi r^2h[/tex]

Where r is the radius and h is the height of the cone.

Putting [tex]\pi =3.14, r=6, h=12[/tex], we get

[tex]V_2=(3.14)(6)^2(12)[/tex]

[tex]V_2=(3.14)(36)(12)[/tex]

[tex]V_2=1356.48[/tex]

Volume of the composite figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=452.16+1356.48[/tex]

[tex]V=1808.64[/tex]

Therefore, the volume of a composite figure is 1808.64 cubic centimetres.

A scatter diagram created with MS Excel shows the data as on the dot plot in a similar question obtained online

The number of students in the group = 92

Part A

The number of students that spend more than 10 hours watching television = 39

Therefore, given that less than half of the student spend more than 10 hours watching television, the statement is false

Part B

The number of students that watch 3 hours of television is the highest than any other time range with 16 students, therefore, the statement is true

Part C

The maximum hours watched by a student in the dot plot is 20 hours, therefore, the statement is true

Part D

The number of hours for which the student watched and which has the highest frequency is 3 hours, therefore, the statement is true as more students have 3 hours as the number of hours watched (16 students) than any other number of hours

Answer:

-4

Step-by-step explanation:

Given the function :

c = – 4n + 60

Where, c = cost of participation ;

n = number of persons

The cost equation can be related to the slope intercept, equation ;

y = mx + b

Where, m = Slope or rate of change

b = intercept

Comparing the slope intercept equation to the cost equation ;

m = - 4 ; Hence, the rate of change of cost is - 4

Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16

[tex]x \approx 8.479[/tex]

Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18

[tex]x \approx 17.382[/tex]

Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12

[tex]x \approx 15.900[/tex]

Step-by-step explanation:

Each triangle is solved by means of trigonometric relations:

Triangle 1 - [tex]m\angle A = 58^{\circ}[/tex], hypotenuse = 16

[tex]\cos 58^{\circ} = \frac{x}{16}[/tex]

[tex]x = 16\cdot \cos 58^{\circ}[/tex]

[tex]x \approx 8.479[/tex]

Triangle 2 - [tex]m \angle A = 44^{\circ}[/tex], adjacent leg = 18

[tex]\tan 44^{\circ} = \frac{x}{18}[/tex]

[tex]x = 18\cdot \tan 44^{\circ}[/tex]

[tex]x \approx 17.382[/tex]

Triangle 3 - [tex]m\angle A = 49^{\circ}[/tex], opposite leg = 12

[tex]\sin 49^{\circ} = \frac{12}{x}[/tex]

[tex]x = \frac{12}{\sin 49^{\circ}}[/tex]

[tex]x \approx 15.900[/tex]

Answer: A. alternate interior angles

Step-by-step explanation:

Line 2 (l₂) and Line 3 (l₃) will be the focus of this question. Since both angle 3 and angle 5 are inside of the lines, they are interior angles. Since they are on alternate sides of the central line (t₁), they are alternate angles. Since they are both alternate and interior angles, they are alternate interior angles.

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Answer:

18.) x = 6

20.) x = 11

Step-by-step explanation:

18.)

We know that line segments FC and ED are parallel to each other so they are congruent to each other:

-1 + 2x = 5 + x

-1 + x = 5

x = 6

20.)

We know that line segments DE and CF are parallel to each other so they are congruent to each other:

18 = -4 + 2x

22 = 2x

22/2 = x

11 = x

Hope this helps!

Answer:

X = 44

Step-by-step explanation:

That square means that the angle is 90°, therefore you can subtract 46 from 90 to find x

90 - 46 = 44

Answer:

44

Step-by-step explanation:

That is a right angle so we just need to subtract 46 from 90, and 90-46 is 44. So 44 is the missing angle
