ANSWER

The area of the triangle is 6.64 square feet.

EXPLANATION

The area of the given triangle is calculated using the formula

[tex]Area = \frac{1}{2} ab \sin(C)[/tex]

where C=62° is the included angle.

a=4.7 ft and b=3.2 ft.

We plug in the values into the formula to get:

[tex]Area = \frac{1}{2} \times 4.7 \times 3.2\sin(62 \degree)[/tex]

Area=6.64 ft² to the nearest hundredth.

Answer:

Step-by-step explanation:

when the two angles are added they are equal to 180 degree. (corresponding angles property)

x+8+3X+2=180

4X+10=180

4X=170

X=44.25 DEGREES

Question 1:

For this case we have that by definition, if a and b are two parallel lines, then the corresponding angles are congruent, that is, we can write 3x + 2 and x + 8 as supplementary angles:

[tex](3x + 2) + (x + 8) = 180\\3x + 2 + x + 8 = 180\\4x + 10 = 180\\4x = 180-10\\4x = 170\\x = \frac {170} {4}\\x = 42.5[/tex]

We look for the value of the angles:

[tex]3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

ANswer:

[tex]x = 42.5\\3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

Question 2:

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

Now, in the equation [tex]y = 2x + 3[/tex]

[tex]m = 2\\b = 3[/tex]

By definition, if two lines are parallel, their slopes are equal. Also, if two lines are perpendicular, then the product of their slopes is -1.

So:

The slope of a line parallel to the given line is:

[tex]m = 3[/tex]

The slope of a line perpendicular to the given line is:

[tex]3 * m = -1\\m = - \frac {1} {3}[/tex]

ANswer:

[tex]3\\- \frac {1} {3}[/tex]

ANSWER

[tex]x =1 +\frac{1}{2} \sqrt{ 10} \: or \: x =1 - \frac{1}{2}\: \sqrt{10}[/tex]

EXPLANATION

The given quadratic equation is

[tex]2 {x}^{2} - 4x - 3 = 0[/tex]

This function is of the form:

[tex] a{x}^{2} + bx + c = 0[/tex]

This implies that:

a=2, b=-4 and c=-3.

We can solve this equation using the quadratic formula:

[tex]x = \frac{ - b \pm \: \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]

We substitute the values into the quadratic formula to obtain;

[tex]x = \frac{ - - 4 \pm \: \sqrt{ {( - 4)}^{2} - 4(2)( - 3)} }{2(2)} [/tex]

[tex]x = \frac{4 \pm \: \sqrt{ 40} }{4} [/tex]

[tex]x = \frac{4 \pm \: 2\sqrt{ 10} }{4}[/tex]

[tex]x =1\pm \: \frac{1}{2} \sqrt{10}[/tex]

[tex]x =1 +\frac{1}{2} \sqrt{ 10} \: or \: x =1 - \: \frac{1}{2} \sqrt{10}[/tex]

Answer:

Your answer is correct

Step-by-step explanation:

Answer:

Step-by-step explanation:

The way it is written is a bit ambiguous. If you mean

(1/6)*x = 2 then your answer is correct. Multiply both left and right by 6

6*(1/6)*x = 6*2

x = 12

If however, the question meant

1/(6x) = 2 then that is a different question.

Multiply both sides by 6x

1/(6x) * 6x = 2 * 6x

1 = 12*x                      

Divide by 12

x = 1/12

Change to a decimal

x = 0.08333333

Everything depends on how it is written. Try both if you can.

Answer: Option A; 19

Step-by-step explanation:

The data is:

We have 40 students.

16 play football

9 play basketball

4 play bot sports.

We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)

N = 16 + 9 - 4 = 12 + 9 = 21

the number of students that do not play basket or football is equal to:

40 - N = 40 - 21 = 19

The correct option is A

Answer:

D. X=1.75

Step-by-step explanation:

To start, let’s divide both sides by 4.

So 3^x =27.48/4

Since we want to solve for x, we take the log_3 of both sides.

So [tex]log_{3}3^x[/tex]=[tex]log_{3}6.87[/tex]

Using the laws of logs, we get

[tex]x*log_{3}3[/tex]=[tex]log_{3}6.87[/tex]

since [tex]log_{3}3[/tex] is 1, we get

X=[tex]log_{3}6.87[/tex]

Using a calculator, we find that x is about 1.75

Question 4) 8.6

Step-by-step explanation:

Mean absolute deviation is the average distance between the data points from the set to the mean point of the data set. It shows the variability in data or how much the data points are spread.

method to calculate Mean absolute deviation:

a. calculate mean

b. calculate absolute deviation of each data point

c. add all the deviations

d. divide absolute deviation by number of points

mean absolute deviation = ∑l[tex]x_{i}[/tex]-xl / n

The given problem has four sub-parts

Solution 1:

Mean= (78+99+90+80+55+56+102+88+60+42)/10

            =  750/10

            =  75

Mean absolute deviation= ( I 78-75 I + I 99-75 I+I 90-75 I + I 80-75 I +

                                             I 55-75 I + I 56-75 I + I 102-75 I + I 88- 75 I +

                                             I 60-75 I + I 42-75 I) /10

         =  (174)/10

        =  17.4

Solution 2:

Mean = (10+13+7+12+9+8+12+10+11+13)/10

              =  (105)/10

              = 10.5

Mean absolute deviation = ( I 10-10.5 I + I 13-10.5 I + I 7-10.5 I + I 12-10.5 I +

                                              I 9-10.5 I + I 8-10.5 I + I 12-10.5 I + I 10-10.5 I +

                                               I 11-10.5 I + I 3-10.5 I) /10

       =   17/10

       = 1.7

Solution 3:

Mean= (1+7+10+5+3+3+6+12+9+4)/10

            =  60/10

            =  6

Mean absolute deviation  = ( I 1-6 I + I 7-6 I + I 10-6 I + I 5-6 I + I 3-6 I +

                                               I 3-6 I + I 6-6 I + I 12- 6 I + I 9-6 I + I 4-6 I) /10

         = (28)/10

        =  2.8

Solution 4:

Mean= (30+46+25+45+18+25+15+32+40+24)/10

            =  300/10

            =  30

Mean absolute deviation  = ( I 30-30 I + I 46-30 I + I 25-30 I + I 45-30 I +

                                               I 18-30 I + I 25-30 I + I 15-30 I + I 32-30 I +

                                               I 40-30 I + I 24-30 I) /10

         = (86)/10

        =  8.6

Step-by-step explanation:

First find the length of RS

x2 = 4

x1 = - 1

y2 = 2

y1 = 2

RS^2 = (2 - 2)^2 + (4 - -1 ) ^2

RS^2 = 0 + 5^2

RS = sqrt(5^2)

RS = 5

That is the length of the diameter. The radius is 1/2 that

r = d/2

d = 5

r = 5/2

r = 2.5

The answer would be 2.5

Answer:

25.5°, 25.5°, 129° and 51°, 64.5°, 64.5°

Step-by-step explanation:

if you read the problem carefully you will notice that there are actually 2 ways of solving this problem. the first is by looking at the arc as if it is across from angle A, while the second is so the arc is across from side BC and bisected by point A (because the triangle is isosceles).

first way:

102/2=51°=m∠A

180-51=129°=m∠B+m∠C

129/2=m∠B=m∠C=64.5°

answers: 64.5°, 64.5°, 51°

second way:

102/2=51

51/2=m∠B=m∠C=25.5°

180-51=129°=m∠A

answers: 25.5°, 25.5°, 129°

Hope this helps!:)

The central angle BOC is twice the measure of arc BC, so it is 204°. Since the circle is 360°, the sum of the other two angles is 156°. Being an isosceles triangle, angles ABC and ACB are equal, thus each is 78°.

To find the measure of the angles of an isosceles triangle ABC inscribed in a circle, with the measure of arc BC being 102°, we utilize the properties of a circle and the fact that an isosceles triangle has two equal angles. In a circle, the angle subtended by an arc at the center is twice the angle subtended on the circumference. Thus, if the measure of arc BC is 102°, the central angle BOC would be 204° (since it's twice the angle at the circumference).

This central angle separates the circle into two segments, one of which is the base of the isosceles triangle. The other two angles of the triangle, angles A and ABC or ACB (since it's an isosceles triangle, these angles are equal), will each occupy the remaining portion of the circle that amounts to 360° - 204° = 156°. Since the angles at B and C are equal in an isosceles triangle, we divide the remaining 156° by 2 to find each angle. Therefore, angle A = 204°, and each of the other two angles is 78°.

Step-by-step explanation:

Given sinP = [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 , hence

tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]

The value of the tanP when sin is equal to 5/13  is 5/12.

We have given that,

[tex]sinP = \frac{5}{13}[/tex]

[tex]sin(\theta)=\frac{Opposite}{hypogenous}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg of 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

taking square root on both sides

[tex]x=\sqrt{144} \\x=12[/tex]

Therefore we get the value of the tanP.

[tex]tanP = \frac{opposite }{adjucent} = \frac{5}{12}[/tex]

Therefore the value of the tanP is 5/12.

Step-by-step explanation:

The amount he is spending PER DAY is always a variable multiplied by its rate. That will be 8d.

Then you have a MAXIMUM amount of 3,000. That means the amount has to be less than or even equal to 3,000 but no more.

So 8d ≤ 3000 would be the answer

I believe the answer would be J. whenever the open part of the sign is towards a number or value, that means it is greater than the other number on the other side. For example 5 is less than 6 so 5 < 6. whenever the sign in between and has a line underneath it, it means it can also be equal to the number. therefore d is the amount per day and you pay that much for 8 days, so you get 8d. Now we know you can spend $3000, but no more. so you would use this sign < with a line drawn underneath it. now you would have 8d <(with a line underneath) 3000. this means that I'd must be equal to $3000 or less than $3000.

Answer:

$164.62

Step-by-step explanation:

Angles C and D are supplementary, meaning they add up to 180 degrees. So, if we add 8u-48 to 5u+46, we get 13u-2. We set that equal to 180, so 13u-2=180. Add the two, so 13u=182. Divide the 13, so u=14. To double check, plug in 14 to both expressions. 8(14)-48 and 5(14)+46. 8(14)-48 is 64. 5(14)+46 is 116. If you add 64+116, you get 180, which proves your answer right! So u= 14

it's 7

you add them all up and get 96, then divide and get 16

add them up again, finding the difference from 16 and divide by 6 and you get 7

the answer is 12 since the sum of the two angles has to equal 180.

first you do

5x+5+115=180

5x+120=180

subtract 120

Step-by-step explanation:

A line has been graphed in the figure attached.

It passes through two points ( 1,1) and (2,4)

Y-intercept of the given line is (-2)

Since equation of a line in the intercept form is

y = mx + c

where m = slope and c = y-intercept

and slope m =  [tex]\frac{y-y'}{x-x'}[/tex]

Therefore, slope m =  [tex]\frac{4-1}{2-1}[/tex]

                                =  [tex]\frac{3}{1}[/tex]
