Solve for the value of s

Answer:

x = 4°

Step-by-step explanation:

All angles in a triangle add up to 180°

16x - 4 + 30 + 90 = 180

Rearrange

16x = 180 - 90 - 30 + 4

16x = 64

x = 4°

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question we have

[tex]m = \frac{5 - 2}{4 - 3} = \frac{3}{1} = 3 \\ [/tex]

We have the final answer as

11/111

Step-by-step explanation:

Let x=0.099099099...

1000x=99.099099..

subtract

999 x=99

x=99/999=11/111

Answer:

1st one) y = x - .8

Step-by-step explanation:

1st one) you start by finding the slope of the line which can be found with y1 - y2/x1 - x2 (in this case: 3.6-2.4/2-1 which = 1/1, or the slope is one). now that we know the slope we need to find the x intercept or the point that the line intercepts the x axis, or when y = 0. We know that that for every one we subtract from x, we subtract one from y (hence the slope 1/1). so when we subtract 1.2 from the y we subtract 1.2 from the x. so the x intercept is -.8. If we put this in y = mx+b we get y = x - .8

2nd one) you do the same thing for the 2nd one then

Answer:

x    -3   -2   -1     0    1   2   3

y    10    4    0   -2   -2

Step-by-step explanation:

The given equation is y=x²-x-2.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

We need to find the y values of the give x values.

Given that, x = -3  -2  -1  0  1  2  3

When x = -3, y = (-3)²-(-3)-2

= 9+3-2 = 10

When x = -2, y = (-2)²-(-2)-2

= 4+2-2

= 4

When x = -1, y = (-1)²-(-1)-2

= 1+1-2

= 0

When x = 0, y = 0²-0-2

= -2

When x = 1, y = 1²-1-2

= -2

When x = 2, y = 2²-2-2

= 0

When x = 3, y = 3²-3-2

= 4

So, the complete table is

х  -3  -2  -1   0   1   2   3

y  10  4   0  -2  -2  0   4

There, the y values of the given x values in the given equation is y = 10, 4, 0, -2, -2, 0, 4.

Answer:

[tex]\boxed {x = -2}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]9 - 4x = 17[/tex]

-Subtract both sides by [tex]9[/tex]:

[tex]9 - 9 - 4x = 17 - 9[/tex]

[tex]-4x = 8[/tex]

-Divide both sides by [tex]4[/tex]:

[tex]\frac{-4x}{-4} = \frac{8}{-4}[/tex]

[tex]\boxed {x = -2}[/tex]

Therefore, value of [tex]x[/tex] is [tex]-2[/tex].

Answer:

trouts = 10 and bears = 14

Step-by-step explanation:

Let number of trouts and bears be x and y respectively.

This means that since he caught 24 trout and bass, we have;

x + y = 24 - - - (eq 1)

Now, average weight of trout is 2.5 pounds and average weight of bass is 8 pounds.

Thus;

2.5x + 8y = 137 - - - (eq 2)

From eq(1), let's make x the subject.

Thus;

x = 24 - y

Put 24 - y for x in eq(2)

2.5(24 - y) + 8y = 137

60 - 2.5y + 8y = 137

5.5y + 60 = 137

5.5y = 137 - 60

y = 77/5.5

y = 14

x = 24 - 14

x = 10

Thus, trouts = 10 and bears = 14

Given:

Jody earns $10 per hour babysitting and $15 per hour doing yardwork.

This week she worked 34 hours and earned $410.

To find:

The system of equations models this situation.

Solution:

Let x represents the number hours she babysat and y represents the number of hours she did yardwork.

Total number of hours is 34.

[tex]x+y=34[/tex]

Total income is $410.

[tex]10x+15y=410[/tex]

Therefore, the required system of equations has equations [tex]x+y=34[/tex] and [tex]10x+15y=410[/tex].

Answer:

4.53%

Step-by-step explanation:

We are told that:

From the question, we have a 6.5 % coupon

Hence = 6.5 × $10

= $65

Price of the bond one year later = $1,037.19

$1,054.47 - $1,037.19

= $17.28

Rate of Return

= ($65.00 - $17.28)/$1,054.47

47.72 ÷ 1054.47 = 0.045254962

0.045254962 × 100 =

4.5254962 %

Approximately = 4.53%

Answer:

(i) we will be finding the acceleration here, in the first 20 seconds the velocity was 10

a = velocity/time

a = 10/20

a = 0.5 ms -2

(ii) difference in distance of the bus and bicycle will be given by formula of velocity

velocity of bicycle

10 * 80 = distance

800 metres

velocity of bus

for first 20 seconds( distance= velocity* time)

200 metres

from 20 seconds to 60 seconds, it will be for 40 seconds

then distance will be,

400 metres

final 20 seconds

200 metres

adding the distances of bus it will be 800 metres.

the difference in distance will be 0 metres.

Answer:

$207

Step-by-step explanation:

Given the following :

Data:

X : Distance From Times Square (city blocks)

Y: Cost of a Room (dollars) (y)

The linear regression model generated for the data :

y = -7.8x + 246.3

y = predicted variable ; - 7. 8 = slope of model ; x = predictor variable ; 246.3 = intercept

Using the model:

The cost of a Room 5 block away :

x = 5

y = -7.8(5) + 246.3

y = - 39 + 246.3

y = $207.3

Answer: kindly check explanation

Step-by-step explanation:

Given the following :

Total area of parknand path way = 74,464 m2.

Dimension of park = 350m by 200m

Using the area of rectangle formula:

Area = Length * width

Area of park = 350m * 200m

Area of park = 70,000

Area of path = (74,464 - 70,000) = 4,464m2

Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m

2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path

Answer:

Step-by-step explanation:

The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.
