A 12 pack of ice-cream sandwiches cost $7.20 and a 9 pack of ice-cream sandwiches costs $4.50. Which package of ice-cream sandwiches is the better buy? ​

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

[tex]m∠ADB = \frac{1}{2} m∠ADC [/tex]

⟹[tex]8x - 3 = \frac{1}{2} \times 74[/tex]

[tex]8x - 3 = 37 ⟹8x = 37 + 3[/tex]

Divide both sides by 8 to find the value of x

[tex]x = \frac{40}{8} [/tex]

Therefore:

[tex]x = 5[/tex]

Step 2: Find slope m

Answer:

26m

Step-by-step explanation:

opp represents the height of the nest from the angle of elevation,adj represents the distance of the farmhouse from the building . Therefore,according to Tan rule (TOA)

Tan30° = opp/adj

opp= tan30° x adj

opp= tan30° x adj

opp = 0.5774 x 28

0pp= 16.12m

the height of the eagle's nest from the ground = 16m + 10m(since the farm house is 10m tall)

the height ...= 26m

Answer:

16 and 64

Step-by-step explanation:

The geometric mean n of two numbers a and b can be given as;

√ab = n

In this question;

a = 16

b = ?

n = 32

So we have

16 * b = 32^2

b = 32^2/16

b = (32 * 32)/16

b = 2 * 32

b = 64

Step-by-step explanation:

replace x in the equation with 3.5

y = -0.72x + 7.7

y = -0.72(3.5) + 7.7

y = -2.52 + 7.7

y = 5.18

Answer:

Answer:

The hypotenuse is 55 miles

Step-by-step explanation:

Given the sides of a right angle triangle as 33 and 44 miles, we want to get the hypotenuse

Mathematically, by Pythagoras’ theorem, the hypotenuse square is the sum of the squares of the other two sides

So we have;

h^2 = 33^2 + 44^2

h^2 = 3025

h = √3025

h =55 miles

Answer:

1. Lin

2. 3 weeks

Step-by-step explanation:

Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Han starts with $100 in his account. He spends $15 each week on lunches.

Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each week to her account.

For hen:

x be the number of weeks

Total amount left = 100 - 15x

Plug x = 4

Total amount left = $40

For Lin:

y be the number of weeks.

Total amount = 25 + 10y

Plug y = 4

Total amount = 25+40 = $65

Lin has more money in his account.

To have the same amount:

100 - 15x = 25 + 10y

x = y

100 - 15x = 25 + 10x

x = 3 weeks

Thus, Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

Answer:

$252

Step-by-step explanation:

The store paid $140 for the suit. Let's first find the 80% of $140.

$140 x 80% = $112

So now we just need to add $112 to $140.

$140 + $112 = $252

Answer:

cos57° = x/51

General Formulas and Concepts:

Trigonometry

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use trig to solve for the missing side length.

Step 2: Set up ratios

We can choose between the 2 angles and have multiple ratios to solve for x.

sin33° = x/51

cos57° = x/51

Hence, we see that the 1st option would be the correct answer.

Answer:

The value of [tex]k[/tex] is -9.

Step-by-step explanation:

If [tex]A(x,y) = (-1,-6)[/tex], [tex]B(x,y) =(3, -12)[/tex] and [tex]C(x,y) = (k,6)[/tex], then [tex]\overrightarrow{BC} = \alpha\cdot \overrightarrow{BA}[/tex]. By vectors sum, we find each vector below:

[tex]\overrightarrow{BA} = A(x,y)-B(x,y)[/tex] (1)

[tex]\overrightarrow{BA} = (-1,-6)-(3,-12)[/tex]

[tex]\overrightarrow{BA} = (-4, 6)[/tex]

[tex]\overrightarrow{BC} = C(x,y)-B(x,y)[/tex] (2)

[tex]\overrightarrow{BC} = (k,6)-(3,-12)[/tex]

[tex]\overrightarrow{BC} = (k-3, 18)[/tex]

By substituting in the equation defined at the begining of this answer:

[tex](k-3, 18) =\alpha\cdot (-4, 6)[/tex]

[tex](k-3, 18) = (-4\cdot \alpha, 6\cdot \alpha)[/tex] (3)

The value of [tex]\alpha[/tex] is:

[tex]6\cdot \alpha = 18[/tex] (3a)

[tex]\alpha = 3[/tex]

If we know that [tex]\alpha = 3[/tex], then the value of [tex]k[/tex] is:

[tex]k-3 = -4\cdot \alpha[/tex]

[tex]k = 3-4\cdot \alpha[/tex]

[tex]k = 3-4\cdot (3)[/tex]

[tex]k = 3-12[/tex]

[tex]k = -9[/tex]

Then, the value of [tex]k[/tex] is -9.

Answer:

5,598 cans are required to empty the vessel

Step-by-step explanation:

The volume of a cylinder of radius r and height h is:

[tex]V = \pi r^2h[/tex]

The volume of a box of dimensions X, Y, and Z is:

V=X.Y.Z

A cylinder of r=1.4 m and height h=1.5 is used to store vegetable ghee. It contains a volume of:

[tex]V_1 = \pi 1.4^2*1.5[/tex]

[tex]V_1=9.236\ m^3[/tex]

Converting to cubic cm:

[tex]V_1=9.236*1,000,000\ cm^3[/tex]

[tex]V_1=9,236,282\ cm^3[/tex]

The volume of each rectangular tin can is:

[tex]V_2=33*10*5=1,650\ cm^3[/tex]

[tex]V_2=1,650\ cm^3[/tex]

The number of cans required to empty the vessel is:

[tex]V_1/V_2=9,236,282/1,650 = 5,598[/tex]

5,598 cans are required to empty the vessel

Answer:

α = 164.5387822595581°

Step-by-step explanation:

Calculate dot product:

a · b = ax · bx + ay · by = 5 · (-7) + (-4) · 3 = - 35 - 12 = -47

Calculate magnitude of a vector:

|a| = ax2 + ay2 = 52 + (-4)2 = 25 + 16 = 41

|b| = bx2 + by2 = (-7)2 + 32 = 49 + 9 = 58

Calculate angle between vectors:

cos α =   a · b

|a|·|b|

cos α =   -47

41 · 58

 = -  47

2378

√2378 ≈ -0.9638111202541978

α = 164.5387822595581°

Step-by-step explanation:

Keenan hiked 15 times as far as Margot. How far did Keenan hike? the total number of miles be m

The Keenan hike is measured in m is [tex]\frac{15m}{16}[/tex]miles.

The given parameters;

Keenan and Margot hiked m miles altogether.

Let the distance Margot hiked = n

Then, the distance Keenan hiked = 15n

The combined distance both hiked: m = n + 15n

Calculating Margot's hiked distance in terms of m is as follows:

m = n + 15n

m = 16n

n=[tex]\frac{m}{16}[/tex]

The calculation for Keenan's hike in terms of miles is

= 15(n)

=15[tex]\frac{m}{16}[/tex]

=[tex]\frac{15m}{16}[/tex]

Thus, the  distance hiked by Keenan in terms of m is [tex]\frac{15m}{16}[/tex]miles.
