Answer:

1 1/2

Step-by-step explanation:

10/14 + 11/14

Since we have a common denominator, we can add the numerators

21/14

Changing from an improper fraction to a mixed number

14/14 + 7/14

1 + 1/2

The required measure of the indicated angle b is 101°.

Use the concept of a triangle is defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

In the given figure,

Interior angle = 79°

And the corresponding exterior angle = b

If we combine both angles,

Then it becomes a complete angle of the line.

Since we know that,

The complete angle of a line = 180 degrees.

Therefore,

79° + b =  180°

Subtract 79° on both sides,

b = 101°

Hence,

The measure of angle b is 101°.

x = the first integer

x + 1 = the second integer

x + 2 = the third integer.

Let's set each of our variables equal to -69

x + x + 1 + x + 2 = -69

Combine like terms

3x + 3 = -69

Subtract 3 from both sides.

3x = -72

Divide both sides by 3

x = -24

The first integer = x = -24

The second integer = x + 1 = -24 + 1 = -23

The third Integer = x + 2 = -24 + 2 = -22

f ( x )  = [tex]x^{3}[/tex] −  2 [tex]x^{2}[/tex]  +  x  +  C

Answer:

  19 m

Step-by-step explanation:

The width is 2 less than the length, so the perimeter is ...

  P = 2(L +W)

  72 = 2(L +(L -2))

  76 = 4L . . . . . . . . add 4

  19 = L

The length of the rectangle is 19 meters.

Answer:

-3,-6

Step-by-step explanation:

Answer:

Ok, we know that the price, per pond of grapes, is $1.99.

Now the function that models the cost of grapes is:

C(x) = $1.99*x

Where x is the number of pounds that you buy.

Here we can assume two things:

1) The grapes are already in bags, so x can be only whole numbers, as x can take only whole numbers, the cost c(x) will be discrete because there are a lot of possible costs that are not accessible.

Then the domain is:

D: {0, 1, 2, 3, 4.....}

And the range is :

R: {0*$1.99. 1*$1.99, 2*$1.99, ...}

2)You can choose any amount of grapes that you want, and then the grapes are weighted when yo pay.  (This has not really sense, but it is fun to analyze the problem in different ways)

Here the weight can take almost any value, because with individual grapes you can have almost any number of pounds.

But the unit that defines the total weight is the weight of a single grape.

Then if you have N grapes (and all of them weight almost the same, let's say M)

The total weight will e N*M

If you add one more grape, the weight is: (N + 1)*M

Then it is still discrete!

As we do not know the mean weight of a grape, we can not find the domain  nor the range in this situation, so the one above is the one that we should consider the correct one.

Answer:

So there are infinite solutions along the line y = 2x-1

Step-by-step explanation:

10x=5y+5

y=2x-1

Substitute y into the first equation

10x = 5(2x-1) +5

10x = 10x-5+5

10x = 10x

This is always true

So there are infinite solutions along the line y = 2x-1

Answer:

-2x + 6

Step-by-step explanation:

Step 1: Write expression

Step 2: Distribute

3x + 6 - 5x

Step 3: Combine like terms

-2x + 6

Answer:

-2x+6

Step-by-step explanation:

first multiply the 3(x+2)

that equals 3x+6-5x

Add like terms

Step-by-step explanation:

Joey gets 17 per week

[tex]17x[/tex] with x the number of weeks

he wants to buy a basketball cap that 43.67

[tex]equation\geq 43.67[/tex]

he has already saved 22.22

[tex]+22.22[/tex]

has to pay 13.45 each week

[tex]-13.45x[/tex]

[tex]17x+22.22-13.45x\geq 43.67\\\\(17x-13.45x)+22.22\geq 43.67\\\\3.55x+22.22\geq 43.67\\\\3.55x\geq 43.67-22.22\\\\3.55x\geq 21.45\\\\x\geq \frac{21.45}{3.55} \\\\x\geq 6.04...[/tex]

but we don't wake a 0.4 of a week so we need the next whole number 7

so it will take 7

Step-by-step explanation:

6x  + 5x+2 + 134 = 180               All triangles have 3 angles = 180. Combine

11x + 136 = 180                            Subtract 136

11x = 180 - 136

11x = 44                                       Divide by 11

x = 44/11          

x = 4

Angles are

5x + 2 = 22

6x   =     24

Step-by-step explanation:

Answer:

Let 0.12 be x.

Here, x is recurring in two decimal places so we'll multiply it by 10-

Now, by subtracting them-

[tex] \\ \implies \sf \: 10x - x = 1.22 - 0.12 \\ \\ \\ \implies \sf \: 9x = 1.1 \\ [/tex]

Now, we'll divide both sides by 9 to get x as a fraction -

[tex] \\ \implies \sf \: x = \frac{1.1}{9} \\ \\ \\ \star \: \large{ \boxed{ \sf{x = \frac{11}{90} }}} \\ [/tex]

Answer:

The meet at first time at starting point after 336 seconds,

Vanu have completed 7 laps while Tanuj has completed 6 laps.

Step-by-step explanation:

Given that Venu and Tanuj take 48 seconds and 56 seconds to

complete a lap respectively.

To meet them again at the startiong point, the  time taken must be multiple of 56 and 48.

So, the minimum time required to meet them again at the startiong point is time taken for first time meet.

Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.

Number of laps by Venu

[tex]=\frac{336}{48}=7[/tex]

Number of laps by Tanuj

[tex]=\frac{336}{56}=6[/tex]
