Step-by-step explanation:

Given that:

Eddie has gone to Luke Base Air Force Show.

Total money available with Eddie = $55

Admission cost = $5

Cost of each soda = $6.25

To find:

The greatest number of sodas that can be bought by Eddie ?

Solution:

Let the greatest number of sodas that can be bought by Eddie = [tex]x[/tex]

Now, the total money spent by Eddie will be equal to the admission fee and the cost for buying the [tex]x[/tex] number of sodas.

Cost for [tex]x[/tex] number of sodas = Cost of one soda multiplied by [tex]x[/tex] = $6.25 [tex]\times x[/tex]

Writing equation as per given statement:

Total money = $55

[tex]55 = 5 +6.25x\\\Rightarrow 6.25x = 55-5\\\Rightarrow 6.25x = 50\\\Rightarrow x = \dfrac{50}{6.25}\\\Rightarrow \bold{x = 8}[/tex]

Therefore, a maximum of 8 number of sodas can be bought.

Answer:

x = 12

Step-by-step explanation:

Supplementary angles add up to 180 degrees therefore (6x + 48) and 60 should add up to 180. Like this:

6x + 48 + 60 = 180

Now solve:

6x + 48 + 60 = 180

6x + 108 = 180

6x = 72

x = 12

Therefore, the answer is x = 12.

I hope this helps!!

Answer:

x = 3

Step-by-step explanation:

You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..

5x - 7 = 2x = 2

Therefore you can then simplify for the value x where you should get teh value 3.

Answer:

y = -3/2x+2

Step-by-step explanation:

The slope for a slope equation is y = mx+b

Since it's decreasing from left to right the first part of the equation (mx) is -#x. The second part of the equation (+b) will be +2 because the y-intercept is (0,2). If it were a negative # then it would be -7, or -4, or - whatever.

Now you have to find the slope. To find the slope simply do y1-y2/x1-x2 or y2-y1/x2-x1. Let's follow this equation. say that (2,-1) is 1 and (4,-4) is 2.

-1+4/2-4 = 3/-2 = -3/2. The equation would be y = -3/2x +2. Let's check our work by substituting  our variables with numbers using the set (2,-1). Pleases tell me if I'm wrong or if this is confusing.

Answer:

q = 4.9

m∠R = 27.1°

m∠S = 136.9°

Step-by-step explanation:

To solve the triangle we will use the cosine rule and the sine rule

In the given triangle

∵ q is the opposite side of ∠Q

∵ s is the opposite side of ∠S

∵ r is the opposite side of ∠R

∵ m∠Q = 16°

∵ r = 8 and s = 12

→ By using the cosine rule to find q

∴ q² = r² + s² - 2 r s cos∠Q

→ Substitute the values of r, s, and ∠Q in the rule above

∵ q² = (8)² + (12)² - 2(8)(12)cos(16°)

∴ q² = 23.43775438

→ Take √ for both sides

∴ q = 4.841255455

→ Round it to the nearest tenth

∴ q = 4.9

→ To find angles R and S we will use the sine rule

∵ [tex]\frac{r}{sin(R)}[/tex] =[tex]\frac{q}{sin(Q)}[/tex] = [tex]\frac{s}{sin(S)}[/tex]

→ Use the first two ratios to find m∠R

∵ [tex]\frac{8}{sin(R)}[/tex] = [tex]\frac{4.841255455}{sin(16)}[/tex]

→ By using cross multiplication

∴ 4.841255455 × sin(R) = 8 × sin(16)

→ Divide both sides by 4.841255455

∴ sin(R) = 0.4554807874

→ Use [tex]sin^{-1}[/tex] to find m∠R

∵ m∠R =  [tex]sin^{-1}[/tex] (0.4554807874)

∴ m∠R = 27.0958732

→ Round it to the nearest tenth

∴ m∠R = 27.1°

∵ The sum of the measures of the angle in a triangle is 180°

∴ m∠S + m∠Q + m∠R = 180°

→ Substitute the values of m∠Q and m∠R

∵ m∠S + 16° + 27.1° = 180°

∴ m∠S + 43.1 = 180

→ Subtract 43.1 from both sides

∴ m∠S = 136.9°

Answer:

The range of the function should be:

-9 ≤ y ≤ 5

Hence, option D is true.

Step-by-step explanation:

We know that the set of values of the dependent variable for which a function is defined.

From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.

i.e.

at y = 5, the graph gets its maximum value

at y = -9, the graph gets its minimum value

Thus, the range of the function should be:

-9 ≤ y ≤ 5

Hence, option D is true.

Answer:

Equation: [tex]2(x+8)+2(3x-5)+23 = 126[/tex]

[tex]x = 12.125[/tex]m

[tex]AB = 20.125[/tex]m

[tex]EF=31.375[/tex]m

Step-by-step explanation:

The equation of the perimeter of this shape can be written as:[tex]2(x+8)+2(3x-5)+23 = 126[/tex] (Sides with the same number of dashes are equal in length)

Which becomes:

[tex]2x+16+6x-10+23=126[/tex]

[tex]8x+29=126[/tex]

[tex]8x=97[/tex]

[tex]x= 12.125[/tex]

Since AB = [tex]x+8[/tex], we can substitute to get the length of AB:

[tex]x+8 = 12.125+8[/tex]

[tex]=20.125[/tex]

We can also use substitution to solve for the length of EF:

[tex]3x-5=3(12.125)-5[/tex]

Answer:

A. 3

B. 2.825

Step-by-step explanation:

Data obtained from the question include:

Number of bedrooms (x) > Frequency(f)

1 >>>>>>>>>>>>>>>>>>>>> 5

2 >>>>>>>>>>>>>>>>>>>> 10

3 >>>>>>>>>>>>>>>>>>>> 15

4 >>>>>>>>>>>>>>>>>>>> 7

5 >>>>>>>>>>>>>>>>>>>> 3

Mode =?

Mean average of bedrooms =.?

A. Determination of the modal average of bedroom.

The mode of a given set of data is the the value with the highest frequency.

Considering the table given in the question above, we can see clearly that 3 has the highest frequency. Hence 3 is the modal average of the bedroom is 3

B. Determination of the mean average of bedroom.

Mean = Σfx / Σf

Σfx = (1×5) + (2×10) + (3×15) + (4×7) + (5×3)

Σfx = 5 + 20 + 45 + 28 + 15

Σfx = 113

Σf = 5 + 10 + 15 + 7 + 3

Σf = 40

Mean = Σfx / Σf

Mean = 113 / 40

Mean = 2.825

Therefore, the mean average of bedroom is 2.825

Answer:

x = 4

y = -7 or (-7, 4)

Step-by-step explanation:

y = -2x + 1

4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it

4x + (-2x + 1) = 9 add like terms

2x + 1 = 9 subtract 1 from both sides

2x = 8 divide both sides by 2

x = 4 since y = -2x + 1 replace x with the value we found

y = (-2) × 4 + 1 = -7
