Answer:

x=229.8

Step-by-step explanation:

We can use a trigonometric ratio to solve for x.

If we use 72 as our reference angle, we can solve for x using cosine: [tex]cos (72)=\frac{71}{x} \\\\x*cos(72)=71\\\\x=\frac{71}{cos(72)}\\ \\x=229.7608=229.8[/tex]

Answer:

[tex]\frac{4}{3}[/tex] or [tex]1\frac{1}{3}[/tex] (don't worry, they are the same thing)

Step-by-step explanation:

[tex]3-1\frac{4}{6}[/tex]

[tex]3-\frac{10}{6}[/tex]

[tex]\frac{18}{6} -\frac{10}{6}[/tex] (18/6 is equivalent to 3, and 10/6 is equivalent to 1 4/6)

[tex]\frac{8}{6}=\frac{4}{3}[/tex] (8/6 is equivalent to 4/3)

Hope this helps!

Answer:19.05

Step-by-step explanation:127 min * (9000m/60min)=19050m=19.05km

Answer:

adult  $10   Children $15

Step-by-step explanation:

4A + 6C = 130

10A + 12C = 280

Multiply the first by -2 to eliminate C

-8A -12C = - 260

10A +12C = 280

   ADD BOTH

2A = 20

A=10    ($10 per adult)

   40+6C = 130

6C = 90

C=15 (15 per child)

Answer:

In explanation

Step-by-step explanation

Ok for me to tell you I'm going to give an example.

Data set=

40,50,60,30,105,19,40

For this data set our mode would be 40 because mode is the number that appears most in a data set and as you can see 40 appears twice while every other number only appears once.

For median=would also be 40.

Because median is the number that is in the middle when you sort them least to greatest so 40 is in the middle when you put them in least to greatest.

The maximum is 105

Because the maximum is the highest number in the data set so 105 is the biggest number.

Range is 86.

For range is the highest number subtracting the lowest number and highest number is 105 and lowest number is 19 so 105 - 19=86

Hope this helps have a great day:)

Answer:

56 units squared

Step-by-step explanation:

First, we want to find the area of the triangle taken out of the top. We can tell that the rectangle area that it's in is 28 units because it's 7 across and 10-6=4.  To find the area of a triangle you just divide that 28 by 2 to get 14. 70-14 is 56. Ik I'm not the best at explaining things so if you have any questions feel free to ask bc I explained this weirdly.

Answer:

25

Step-by-step explanation:

" • " means multiply.

The value of √25 = 5

-5•-√25

= -5 x -5

= 25

Shaqquille's expected value is 0.56 points.

Step-by-step explanation:

Situations:

1) he makes 1st shot + he makes 2nd shot

P(A) = 0.4 · 0.4 = 0.16  ( 16 % )

2) he makes 1 st shot + he misses 2nd shot

P(B) = 0.4 · 0.6 = 0.24   ( 24 % )

3) he misses 1st shot and he has no more attempts

P (C) = 0.6 ( 60 %)

0.16 · 2 + 0.24 · 1 + 0.6 · 0 = 0.32 + 0.34 = 0.56

The expected value is 0.56 points.

Answer:

[tex]\boxed{\underline{\tt B.\:x=-1}}[/tex]

Step-by-step explanation:

[tex]\tt 8=2^{(x+4)}[/tex]

(First, convert both sides to the same base):-

[tex]\tt 2^3=2^{x+4}[/tex]

(Now, cancel the base of 2 on both sides):-

[tex]\tt 3=x+4[/tex]

(Subtract 4 from both sides):-

[tex]x+4-4=3-4[/tex]

[tex]\tt x=-1[/tex]

~

Solution:

Step-1: Find the missing side length using Pythagoras theorem:

Step-2: Find the area of the rectangle:

Apply Pythagorean theorem

Answer:

300 calories is lost in 30 minutes

Step-by-step explanation:

if we divide the x axis in 10s and the y axis in 100s,

then when we check the 30 min mark on x axis and the graph line, it corresponds goes on to correspond to the 300 mark on y axis.

Step-by-step explanation:

Answer:

There are 10 spelling questions and 5 vocab questions

Step-by-step explanation:

5 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:x+y=15

5x + 10y= 100

So: x+y=15

x = 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10

Answer:

Distance the comet travelled: x

1 day = 24 hours

24 * 8 = 192 hours

x = 264,000 * 192 = 50,688,000 (because speed = distance/time, so distance = speed * time)

Answer:

1.8 (the yearly fee)

Step-by-step explanation:

The slope of an equation is how the line will move on the graph. Since we already have the fixed price of 39 dollars, that will be the y-intercept of the graph, or where we start with our line. Since each year the fee is 1.8, the line changes by 1.8 in y for every x.
