Help!!!!!!!!!!!!!!!!!!!!!!

Answer:

see below (I hope this helps!)

Step-by-step explanation:

Whole numbers are the integers that are greater or equal to 0. Basically, they are 0, 1, 2, 3....

Rational numbers can be written in the form a / b (where b ≠ 0 and a and b are integers (integers are ..., -1, 0, 1, ...))

Therefore, 4 rational numbers that are not whole numbers could be -5, -1, 0.5, and 3/4.

Answer:

one angle 100

another angle=80

Step-by-step explanation:

supplementary angles =180

4x+5x=180

9x=180

x=180/9=20

one angle=5x=5(20)=100

another angle=4x=4(20)=80

100+80=180

Answer:

Step-by-step explanation:

Let the ratios be 4x and 5x

[tex] \sf4x + 5x = 180[/tex] ( sum of supplementary angle )

Collect like terms

⇒[tex] \sf{9x = 180}[/tex]

Divide both sides of the equation by 9

⇒[tex] \sf\frac{9x}{9} = \frac{180}{9} [/tex]

Calculate

⇒[tex] \sf{x = 20}[/tex]

Value of x = 20

Now, let's replace the value,

⇒[tex] \sf4x = 4 \times 20 = 80[/tex]

⇒[tex] \sf5x = 5 \times 20 = 100[/tex]

Answer:

[tex]a \: 36.5[/tex]

Step-by-step explanation:

cos51° = AC/58

AC = cos51° x 58

AC = 36.5

Answer:

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find AC.

To find AC we use cosine

cos∅ = adjacent / hypotenuse

From the question

AC is the adjacent

AB is the hypotenuse

So we have

[tex] \cos(51) = \frac{AC}{AB} [/tex]

[tex]AC = 58 \cos(51) [/tex]

The required surface area of given triangular prism is 391.2 cm².

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
In the figure,

From the figure,
length = 14 cm
height = 6.9 cm

Answer:

$457.54 total

Step-by-step explanation:

Just add the numbers altogether:

274.96

 77.00

 89.20

 16.38

$457.54 total

The required total monthly cost of owning and maintaining a car, given the information shown, is $457.54.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
To find the total monthly cost of owning and maintaining a car, we need to add up the monthly car payment, the monthly insurance cost, the average cost of gasoline per month, and the average maintenance cost per month.

Adding these values, we get:

Total monthly cost = Monthly car payment + Monthly insurance cost + Average cost of gasoline per month + Average maintenance cost per month

= $274.96 + $77.00 + $89.20 + $16.38

= $457.54

Therefore, the total monthly cost of owning and maintaining a car, given the information shown, is $457.54.

Answer:

[tex]solution set={n/n > -13/5}[/tex]

Step-by-step explanation:

[tex]5n + 3 > -10\\subtracting 3 on both sides\\5n + 3-3 > -10-3\\5n > -13\\n > -13/5 is the answer[/tex]

hope it will help :)

Isolate n:

5n + 3 > -10

Subtract 3 from both sides:

5n > -13

Divide both sides by 5:

n > -13/5

n > -2.6

An integer is a whole number, so the smallest whole number that would make the statement true would be -2:

5(-2) + 3 = -10 +3 = -7

5(-3) + 3 = -15 + 3 = -10

Since -7 is greater than -10, the answer is -2

Answer:

BC = 9

Step-by-step explanation:

Given AC = 26

BC=7x + 2

AB = 9x + 8  

Since BC and AB are two parts of AC. Therefore we can write in the following form.

AC = AB +BC

Now insert the given values in the above formula.

26 = 9x + 8 + 7x + 2

26 = 16x + 10

26 – 10 = 16x

16 = 16x

x = 16 / 16  

x = 1

Now insert x = 1 in BC=7x + 2

BC = 7 (1) + 2

BC = 9

Sum of 20 numbers is 9

To find

Sum of these numbers after increasing each number by 0.03

Solution :-

→ We have to increase each number by 0.03. It means that we have to add 20 times 0.03.

→ So the increase in sum of number will be 20(0.03)

→ 20(0.03) = 0.6

→ Earlier sum was 9.

After increase oof 0.6 new sum is 9+0.6

Explanation:

We know the total amount of spaghetti sauce is 20.5 cups; additionally, each container can be filled with a maximum of 2.5 cups of this sauce. In this context, the process to know the number of containers Mr. Rush needs to store all the sauce is to divide the total amount by the amount each container can hold.

20.5 cups of sauce ÷ 2.5 cups per container = 8.2 containers

This means 8 containers can be completely filled and a ninth container is required to hold the small amount of the sauce missing (0.2)

0.375r-0.0625=0.25+r

Answer:

A. 15

Step-by-step explanation:

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

Hence,

(2x + 15)° = 1/2[(10x + 20)° - 80°]

2(2x + 15)° = (10x - 60)°

4x + 30 = 10x - 60

60 + 30 = 10x - 4x

90 = 6x

90/6 = x

15 = x

x = 15

2a=12

a=6 :)

Answer:

[tex]\Huge \boxed{a=6}[/tex]

Step-by-step explanation:

[tex]a-(7-a)=5[/tex]

We need to isolate the [tex]a[/tex] variable on one side of the equation to find the value.

Distribute the negative sign.

[tex]a-7+a=5[/tex]

Combine like terms.

Divide both sides of the equation by 2.

[tex]\bold{\text{Answer:}\quad f(x)=\bigg\{\begin{array}{ll} -x-2&;x<0\\ -\frac{1}{2}x&;x\geq0 \end{array}}[/tex]

Step-by-step explanation:

Find the equation of each line in Slope-Intercept form: y = mx + b

Line 1 passes through (-5, 3) and (0, -2)   -->   m = -1,  b = -2

                                                                   -->  y = -x - 2

Line 2 passes through (0, 0) and (4, -2)   -->   m = -1/2,  b = 0

                                                                   -->   y = -(1/2)x + 0

Now that you have the equations, evaluate which x-values are included.

Line 1: open dot at x = 0 and line goes to the left        -->  x < 0

Line 2: closed dot at x = 0 and line goes to the right   --> x ≥ 0

Now you have all the information you need to write the piecewise function:

                                [tex]\large\boxed{f(x)=\bigg\{\begin{array}{ll} -x-2&;x<0\\ -\frac{1}{2}x&;x\geq0 \end{array}}[/tex]

The piece wise function can be written as

[tex]f(x) = -x-2 \; for\; x < 0[/tex]

[tex]f(x) = \dfrac{-1}{2}x \; for\; x \geq 0[/tex]

The Equation of line passing through  [tex](x_1,y_1)\; and \; (x_2,y_2)[/tex] can be given  by equation (1)

[tex]y -y_1 = \dfrac{y_2 -y_1 }{x_2 - x_1} (x-x_1) ........(1)[/tex]

The equation of line passing through (0,-2) and (-5,3) =

[tex]y-(-2) = \dfrac{3-(-2)}{-5-0}\times (x-0)[/tex]

[tex]y +2 = -x\\y = -x -2 ......(2)[/tex]

Similarly the line passing through (0,0) and (4,-2) =

[tex]y- 0 = \dfrac{-2 -0}{4-0} (x-0)\\y = \frac{-1}{2} x......(3)\\2y =-x \\x +2y =0[/tex]

The first line has an open circle at (0,  -2) and continues up through (-5, 3) with an arrow instead of an endpoint.

The second line has a closed circle at (0, 0) and continues down with a negative slope through (4, -2) with an arrow instead of an endpoint. [tex]f(x) = \dfrac{-1}{2}x \; for\; x < 0[/tex]

Hence the piece wise function can be defined by equations (2) and (3)

[tex]f(x) = -x-2 \; for\; x < 0[/tex]

[tex]f(x) = \dfrac{-1}{2}x \; for\; x \geq 0[/tex]
