Step-by-step explanation:

35/8=4.something

that answer*20=87.5

Answer:

dfq

Step-by-step explanation:

1.

10x + 8 = 3(x – 2)

10x + 8 = 3x - 6

10x - 3x = -8 -6

7x = -14

x = -14/7

x = -2

2.

10x + 8 = 3x

10x - 3x = -8

7x = - 8

x = -8/7

The smaller the angle subtended by a side, the smaller the length of the

side.

The correct responses are;

Question 1: The list of sides from shortest to longest are;

From the given diagram, we have, the measure of the third angle, ∠O, is

found as follows;

∠O = 180° - 54° - 61° = 65°

Therefore, ∠O = The largest angle

We get;

The longest side is opposite the largest angle, which gives;

The shortest side is the side opposite ∠N (54°)= [tex]\overline{MO}[/tex]

The next shortest side is the side opposite ∠M(61°) = [tex]\overline{NO}[/tex]

The longest side is the side opposite ∠O(65°) = [tex]\overline{MN}[/tex]

a) The time spent training on Tuesday = 60 + 10 = 70 minutes

The time spent training on Thursday = 50 + 30 = 80 minutes

The time spent training on Friday = 45 + 40 = 85 minutes

Therefore, the day the athlete spent the longest total amount of time training is on Friday

b) The time spent training on Monday = 10 + 20 = 30 minutes

The time spent training on Wednesday = 20 + 15 = 35 minutes

Therefore, we get;

30, 35, 70, 80, and 85

The median total number of minutes the athlete spent training each day =

70 minutes

c) The time spent strength training = 20 + 10 + 15 + 30 + 45 = 120

The total number of minutes the athlete spent training = 70 + 80 + 85 + 30

+ 35 = 300

[tex]\mathrm{The \ percentage \ spent \ on \ strength \ training} = \dfrac{120}{300} \times 100 = \underline{40 \%}[/tex]

d) The mean number of minutes spent on strength training is found as follows;

[tex]Mean_{strength} = \dfrac{120}{5} = 24[/tex]

The mean number of minutes spent on aerobic training is found as follows;

[tex]Mean_{aerobic} = \dfrac{10 + 60 + 20 + 50 + 40}{5} = 36[/tex]

[tex]Mean_{strength} +Mean_{aerobic} = 24 + 36 = 60[/tex]

The mean total number of minutes spent training, [tex]Mean_{total}[/tex] = [tex]\dfrac{300}{5}[/tex] = 60

around 19 minutes ^^

(18.85 minutes)

Mary can allocate to each chore around 18.85 minutes.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that Mary has 2 1/5 hours before she needs to meet her friend. She needs to take care of 7 chores before then.

Hence, we get

2 and 1/5 hours = 132 minutes (120 + 12)

thus, Mary will have 132/7 = 18.85714285714286 minutes for each chore.

Or around 18.85 minutes for each chore

Therefore, she can allocate to each chore around 18.85 minutes.

Answer:

Step-by-step explanation:

To find this, lets make a equation.

We have the expression 8b - 27, lets set this equal to -11 and solve:

8b -27 = -11

Now lets solve.

Lets add 27 to both sides to get 8b alone:

8b = 16

Now lets divide by 8:

b = 2

So our answer is 2.

Answer:

1/9

Step-by-step explanation:

4 people use all three facilities, then

16 - 4 = 12 people use the gym and the track and do not use the pool;

9 - 4 = 5 people use the pool and the track and do not use the gym;

19 - 4 = 15 people use the gym and the pool and do not use the track.

At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is 4/36

Answer:

the desired equation is y = (-1/3)x + 6

Step-by-step explanation:

Let the given line be A:  y=3x+2

The slope of line A is m = 3.

The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A:  m = -(1/3).

The particular perpendicular line that passes through (3, 5) is then

5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.

Thus, the desired equation is y = (-1/3)x + 6

Step-by-step explanation:

Answer:

5 Motorcycles are used

30÷6= 5

5×5= 25

30-24=5

so the answer is 5

Answer:

5 out of the 30 motorcycles are used

Step-by-step explanation:

First, we should look at what we know. We know that there are 30 motorcycles in total. As a fraction, that'd be 30/30. We also know that of that 30, the equivalent of 5/6 are brand new.

Our next step is to figure out how much 5/6 is out of 30. Since we know that in total there 30/30 motorcycles, we need to convert 5/6 to have a denominator of 30. So what times 6 equals 30.

30 ÷ 6 = ?    opposite of 6 x ? = 30

5                   divide

So now we now that 6 times 5 equals 30. What we do to the denominator we must do to the numerator.

[tex]\frac{5}{6}[/tex] × [tex]\frac{5}{5}[/tex]    

[tex]\frac{25}{30}[/tex]

Now we know that 25 of the 30 motorcycles are new and all we need to do is subtract that 25 from the total 30 to get 5. This tells us that 5 of the total motorcycles are used.

The graph shown represents an absolute function.

The equation of the graph is [tex]\mathbf{y = -\frac 12|x|}[/tex]

Considering the straight on the right, we have the following points

[tex]\mathbf{(x,y) = (0,0) (4,-2)}[/tex]

Start by calculating the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{-2 - 0}{4-0}}[/tex]

[tex]\mathbf{m = \frac{-2 }{4}}[/tex]

Simplify

[tex]\mathbf{m = -\frac{1}{2}}[/tex]

So, the slope of the line is -1/2

The equation is then calculated as:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

This gives

[tex]\mathbf{y = -\frac 12(x -0) + 0}[/tex]

[tex]\mathbf{y = -\frac 12(x)}[/tex]

Represent x as an absolute value

[tex]\mathbf{y = -\frac 12|x|}[/tex]

Hence, the equation of the graph is [tex]\mathbf{y = -\frac 12|x|}[/tex]
