Answer:

y = 167°

Step-by-step explanation:

The vertex of the triangle = 154° ( alternate angle to 154° )

The triangle has 2 equal legs so is isosceles with 2 base angles congruent

base angle = [tex]\frac{180-154}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13°

base angle and y are adjacent angles, lie on straight line AB and sum to 180°

y + 13° = 180° ( subtract 13° from both sides )

y = 167°

Answer:

The x intercept is -8

Step-by-step explanation:

To find the x intercept, set y = 0 and solve for x

5x - 10y + 40 = 0

5x - 10(0) +40 =0

5x +40 = 0

Subtract 40 from each side

5x = -40

Divide by 5

5x/5 = -40/5

x = -8

The x intercept is -8

Answer:

B

Step-by-step explanation:

y = k/(x + 3)

Let x = 2

Let y = 8

k = ?

8 = k/(2 + 3)      Combine the terms on the right

8 = k/(5)            Multiply both sides by 5

8*5 = k

k = 40

Let x = 7

y = 40/(7 + 3)

y = 40/10

y = 4

Answer: [tex]10.72\ cm[/tex]

Step-by-step explanation:

Given

Radius of circle [tex]r=14\ cm[/tex]

Length of chord is [tex]l=18\ cm[/tex]

Suppose the distance between the chord and center is x

From figure, we can write

[tex]\Rightarrow r^2=x^2+9^2\\\Rightarrow 14^2=x^2+9^2\\\Rightarrow x^2=196-81\\\Rightarrow x^2=115\\\Rightarrow x=\sqrt{115}\\\Rightarrow x=10.72\ cm[/tex]

Answer:

Temperature after 10 minute = 27.9 degree Celsius

Step-by-step explanation:

Current temperature, P = 100 degree Celsius

% rate in temperature loses = 12% per minute = 0.12

Time,  t = 10 minutes

Temperature after t minutes ,

                                           [tex]= P ( 1 - r )^t\\\\=100( 1 - 0.12)^10\\\\=100(0.278500976)\\\\=27.85[/tex]

                                           = 27.9 degree Celsius

Answer: 43

Step-by-step explanation:

Lets start with the result. First add the number you subtracted with 73

= 73+13=86

Now they had doubled it, now we instead divide it as it was multiplied. Division is the opposite of Multiplication.

86/2= 43

Hence the Answer or the First Number was 43

Answer:

Step-by-step explanation:

For the data collected by Martin from students about whether they played a musical instrument, the relative frequency of a boy playing an instrument is 0.348.

Relative frequency of an event is the measure of something happens relative to the total outcomes of that event.

The relative frequency can be given as,

[tex]f_r=\dfrac{f}{n}[/tex]

Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.

The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.

Martin collected data from students about whether they played a musical instrument.

The table shows his results.

Here, the total number of boys are 92 and the total number of boys who play instrument is 32. Thus, the relative frequency is,

[tex]f_r=\dfrac{32}{92}\\f_r=0.348[/tex]

Thus, for the data collected by Martin from students about whether they played a musical instrument, the relative frequency of a boy playing an instrument is 0.348.

Answer:

  40°

Step-by-step explanation:

The side adjacent to the angle of interest and the hypotenuse are given, so the cosine relation is relevant.

  Cos = Adjacent/Hypotenuse

  cos(?) = 46/60

  ? = arccos(46/60) ≈ 39.9445°

  ? ≈ 40°

Answer:

O = 29

P = 61

Step-by-step explanation:

90 = (x+3) + (2x+9)

90 = 3x + 12

90 - 12 = 3x

78 = 3x

x = 26

26 + 3 = O = 29

(26 * 2) + 9 = P = 61

61 + 29  = 90 = Complementary Angles

Answer:

p(r-s) = 2r

pr - ps = 2r

pr - 2r = ps

r(p-2) = ps

[tex] r = \frac{ps}{p - 2} [/tex]

Answer:

r = ps/(p-2)

Step-by-step explanation:

distribute the 'p' first to get:

pr-ps = 2r

add 'ps' to each side to get:

pr = 2r+ps

subtract '2r' from each side to get:

pr-2r = ps

factor out the 'r' to get:

r(p-2) = ps

divide each side by 'p-2' to get:

r = ps/(p-2)

Answer:

1/3

y = -3x +15

Step-by-step explanation:

you do this step by step.

just think what you need. and then you get all of that one after the other.

so, we need the middle point between D and O.

for this we need to know the length of DO.

and we need the slope of DO, so that we can then calculate the perpendicular slope. with that slope we then build the line going through the middle point as well but with the perpendicular slope.

so, length of DO.

Pythagoras for the triangle of the differences between the individual coordinates.

DO² = (9- -3)² + (8-4)² = (9+3)² + 4² = 144 + 16 = 160

DO = sqrt(16×10) = 4×sqrt(10)

the distance D-middle is half of DO = 2×sqrt(10)

DO/2 => DO²/4 = 144/4 + 16/4 = 36 + 4 = 6² + 2²

=> we have to add to the coordinates of D 6 in x and 2 in y direction to get the middle point :

(-3 + 6, 4 + 2) = (3, 6)

the slope of DO

the slope of a line is the ratio of y/x representing the change of y with the change of x. it is the factor of x in the line equation.

for DO we know that when x changes by 12 (difference of the x values of D and O), then y changes by 4.

so, the slope is 4/12 = 1/3.

perpendicular slope of 1/3

we flip x and y and also change the sign, as when the original line goes up, then the y line goes down. and vice versa.

so, the perpendicular slope is -3/1 = -3

the equation of the perpendicular line through the middle point is

y = -3x + c

for c we need to use the coordinates of the middle point (3, 6)

6 = -3×3 + c

6 = -9 + c

c = 15

so our line is

y = -3x + 15

Answer:

Step-by-step explanation:

shipping container is in the shape of a Right rectangular prism with the length of the 12 feet away the 8.5 feet and the height of 4 feet. The container is completely filled with contents that weigh on average 0.25 pounds per cubic foot what is the weight in pounds of the contents in the container

Right rectangular prism is a cuboid

Volume of Right rectangular prism = 12 * 8.5 * 4  = 408 cubic feet

Content Density = 0.25 pounds per cubic foot

Density = Mass / Volume

=>  0.25  = Weight of contents in container / Volume of container

=> 0.25 = Weight of contents in container / 408

=> Weight of contents in container  = 0.25 * 408

=> Weight of contents in container  = 102 pounds

Answer:

8 days

Step-by-step explanation:

Let us represent the number of days as x

For Tina

Tina currently has $60 and is earning $4 a day dog walking.

= $60 + $4 × x

= 60 + 4x

For Tony

Tony has $68 and is spending 3$ a day on candy!

= $68 + $3 × x

= 68 + 3x

To calculate the number of days that they will both have the same amount of candy we equate both equations to each other

60 + 4x = 68 + 3x

Collect like terms

4x - 3x = 68 - 60

x = 8 days

Therefore, they will both have the same amount of candy in 8 days
