Step-by-step explanation:

Answer:

Let x = cost of your friend's lunch.

x + x + 3 = 19

x= 8

Answer:

Your friend lunch bill is $8

Step-by-step explanation:

The bill for you and your friend lunch = $19

Meaning the sum of your lunch bill and your friend bill is $19.

To find how much your friend bill is,

Let represent your friend bill to be x and your bill to be y.

Therefore: x + y = $19

Given that your bill is $3 more than your friend.

Simple means; your bill = your friend bill + 3

Since x represent your friend bill and y represent your bill

So

y = x + 3

Therefore from: x + y = $19

Substitute the value of y = x+3

x + y = $19

x + x + $3= $19

2x = $19 - $3

2x = 16

x = 16/2

x = $8

Since x = your friend bill.

Therefore:.

Your friend lunch bill is $8

The equation of proportional situation is y = ax.

Therefore your answer is y = 14x

Hello.

Y= 2/7

Step 1: Simplify both sides of the equation.

5y+2−3(4y)=0

5y+2+−12y=0

(5y+−12y)+(2)=0(Combine Like Terms)

−7y+2=0

Step 2: Subtract 2 from both sides.

−7y+2−2=0−2

−7y=−2

Step 3: Divide both sides by -7.

−7y/−7=−2/−7

y=2/7

Have a nice day.

Answer:

V = 339.3 cm³; L = 203.9 cm²; A = 317.0 cm²  

Step-by-step explanation:

a) Volume

The formula for the volume (V) of a cone is

V = ⅓πr²h

V = ⅓π × 6² × 9

V = ⅓π × 36 × 9

V = 108π cm³

V ≈ 339.3 cm³

=====

Curved surface area  

The formula for the lateral surface area (L) of a cone is

L = πr√(r² + h²)

L = π×6√(36 + 81)

L = 6π√[9(4 + 9)]

L = 6π√(9 × 13)

L = 18π√13 cm²

L ≈ 203.9 cm²

===============

b) Base surface area

The base is a circle, so the formula for base surface area (B) is

B = πr²

B = π×6²

B = 36π cm²

B ≈ 113.1 cm²

=====

Total surface area

A = L + B

A = 18π√(13 +36π)

A = 18π(2 + √13) cm²

A ≈ 203.9 + 113.1

A ≈ 317.0 cm²

Problem 1)

This question is incomplete. It asks us to find something, but doesn't say what to find. It's literally blank after the word "find" which suggests your teacher made a typo. Please get back to me on this. Thanks.

===================================

Problem 2)

Angles GAR and GAT are supplementary because they are a linear pair. They form a straight angle. So we add up the expressions of x for each of these angles, solve for x, and use this to find angle GAR.

(angle GAR) + (angle GAT) = 180

(5x) + (3x+4) = 180

8x+4 = 180

8x+4-4 = 180-4

8x = 176

8x/8 = 176/8

x = 22

Note: now that I reached this point I realize that this might be the answer to problem 1; however, I'm not 100% sure because of the incomplete problem.

Use this x value to find angle GAR

angle GAR = 5*x

angle GAR = 5*22

angle GAR = 110

Unfortunately this answer isn't listed. I'm thinking your teacher made another typo.

===================================

Problem 3)

Answer: angle GAR and angle ABQ are corresponding angles.

Thankfully this answer is listed. Corresponding angles are angles that are on the same side of the transversal line and they are either both above or below the parallel lines they are next to. In this case, they are both above the parallel line counerparts.

===================================

Problem 4)

Corresponding angles are congruent as long as we have a set of parallel lines. So that means angle ABQ is equal to angle GAR. So angle ABQ is also 110 degrees

===================================

Problem 5)

angle BAT = angle GAR,  because they are vertical angles

angle BAT = 110

angle BAT = (angle BAD) + (angle DAT)

(angle BAD) + (angle DAT) = angle BAT

(100) + (angle DAT) = 110

angle DAT = 110-100

angle DAT = 10

angle ADB = angle DAT,  because they are alternate interior angles

angle ADB = 10

Final Answer: 10 degrees

Answer: $0.58

Step-by-step explanation:

Let x represent pencil and y represent eraser

10x + 7y = 4.23   →   1(10x + 7y = 4.23)   →   10x + 7y =  4.23

3x  + y  = 0.95   →  -3(3x  + y  = 0.95)   →   -21x - 7y = -6.65

                                                                    -11x         = -2.42

                                                                  ÷-11             ÷-11      

                                                                         x        = 0.22  

      3x + y = 0.95

3(0.22) + y = 0.95

   0.66 + y = 0.95

               y = 0.29

2y = 2(0.29)  = 0.58

Answer:3600

Step-by-step explanation:

Answer:

The number is 34.

Step-by-step explanation:

Let the number be x.

As per the statement: if 5.5% of it is 17% of 11.

⇒ 5.5% of x is 17% of 11.

"5.5%of x" means [tex]\frac{5.5}{100} \times x[/tex]

"17% of 11" means [tex]\frac{17}{100} \times 11[/tex]

then;

[tex]\frac{5.5x}{100} = \frac{17 \times 11}{100}[/tex]

Multiply by 100 on both sides, we get;

[tex]\frac{5.5x}{100} \times 100 = \frac{17 \times 11}{100} \times 100[/tex]

Simplify:

[tex]5.5x = 187[/tex]

Divide both sides by 5.5 , we get;

[tex]\frac{5.5x}{5.5} = \frac{187}{5.5}[/tex]

Simplify:

x = 34

Therefore, the number is 34.

Answer:

Step-by-step explanation:

First we must find 17% of 11.

0.17 x 11 = 1.87

So we know 5.5% of "a number" or "x" is equal to 1.87

0.055x = 1.87

x = 1.87/0.055

x = 34

Answer:

Mary's age is 16.8 years

Jane's age is 11.2 years

Step-by-step explanation:

Let's assume Jane was x years old

Mary is twice as old as Jane a long time ago

so, Marry's age =2x

difference in age =2x-x=x years

It means that Marry is x year older than Jane

now, we have

Mary was as old as Jane is now

or we can say that

Jane is as old as Mary was

we know that

Mary =2x years

so, Jane age becomes

Jane=2x years

and we have got

As Mary is x years older than Jane

so, Mary's age =2x+x=3x years old now

now, we are given

The sum of their ages is 28

So,

Mary's age + Jane's age =28

[tex]3x+2x=28[/tex]

[tex]5x=28[/tex]

[tex]x=5.6[/tex]

Mary's age is

[tex]=3\times 5.6[/tex]

[tex]=16.8[/tex]

Jane's age is

[tex]=2\times 5.6[/tex]

[tex]=11.2[/tex]

[tex]y=35\cdot (1.6)^x.[/tex]

Step-by-step explanation:

Find the exponential function in a form [tex]y=a\cdot b^x.[/tex]

1. At x=0,

[tex]35=a\cdot b^0=a.[/tex]

2. At x=1,

[tex]56=35\cdot b^1\Rightarrow b=\dfrac{56}{35}=\dfrac{8}{5}=1.6.[/tex]

Therefore, the expression for the exponential function is

[tex]y=35\cdot (1.6)^x.[/tex]

Note that

[tex]y(-1)=35\cdot (1.6)^{-1}=\dfrac{35}{1.6}=21.875[/tex]

and

[tex]y(2)=35\cdot (1.6)^2=35\cdot 2.56=89.6.[/tex]

The exponential growth function represented by the provided set of ordered pairs is[tex]y = 35 \times 1.6^x,[/tex] where 'a' is the initial value and 'b' is the growth factor derived from the given points.

To begin determining the underline equation of this exponential growth function, we first need to recognize that the general form of an exponential function is[tex]y = ab^x[/tex] , where a is the initial value (the output when x=0) and b is the growth factor.

In the provided set of ordered pairs, when x = 0, y = 35.  Therefore, a = 35. Now, to calculate b, we could apply the function to the point (1,56). We know that[tex]56 = 35\times b^1,[/tex]which simplifies to 56 = 35b.  Solving for b gives us b ≈ 1.6 (approximation).

So, the exponential growth function that corresponds to these ordered pairs is[tex]y = 35\times 1.6^x.[/tex]

Step-by-step explanation:

Aiden's father will be 61 in 5 years:

61 - 5 = 56

Since Aiden is 1/7 of his father's age just divide his father's age by 7:

56 ÷ 7 = 8     Aiden is currently 8 years old.

Aiden                 his father                         is he 1/5 his fathers age

9                           57                                   9 x 5 = 45  NO

10                          58                                  10 x 5 = 50  NO

11                            59                                  11 x 5 = 55   NO

12                            60                                 12 x 5 = 60  YES

Aiden is 1/7 of his father's current age, and his father is currently 56. Given that we want Aiden's age to be 1/5 of his father's, the number of years that would need to pass is 14 years.

Firstly, let's determine Aiden's current age and his father’s current age. We know that Aiden's age is 1/7 of his father’s age, and that his father will be 61 in five years, meaning that his father is currently 56. Thus, Aiden, being 1/7 of his father’s age, is 8 years old.

Let's denote the number of years that we are looking for as 'x'. In 'x' years, Aiden will be 8+x years old, and his father will be 56+x. For Aiden’s age to be 1/5 of his father’s age, the following must be true: (8+x) = 1/5*(56+x). Solving this equation gives us x = 14. Therefore, in 14 years, Aiden's age will be 1/5 of his father's age.
