The least number of visits he needs to make in order to earn a free movie ticket is approximately 15 visits.

Points received for signing up = 85 rewards points

Points received for each visit to the movie theater = 10.5 points

Points needed for a free movie ticket = 240 points

Number of visits = x

85 + 10.5x ≤ 240

Answer: 7 units

Step-by-step explanation:

Answer:

x = 147

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7 , then

sum = 180° × 5 = 900°

sum the interior angles and equate to 900

x + 141 + 112 + 129 + 106 + 139 + 126 = 900

x + 753 = 900 ( subtract 753 from both sides )

x = 147

Answer:

First question mark is 4, second question mark is 64

Step-by-step explanation:

For the first question mark, 7 is half of 14, and half of 8 is 4, so they would be the same ratio, and then for the second, 12 to 24 is just one half, meaning you would need to find double 32, which is just 64

4x -6 + 4 = 2x + 10  Combine like terms

4x -2 = 2x + 10  Subtract 2s from both sides of the equation

2x -2 = 10  Add 2 to both sides

2x = 12  Divide both sides by 2

x = 6

Plug in 6 for x in AC

Based on the given, the variable p from the expression 4.45p represent pounds of tomatoes sold.

Algebra is a system for computation using letters or other symbols to represent numbers, with rules for manipulating these symbols.

The cost of the tomatoes for a number of packages = 4.45p

If the store sold 2 1/4 pounds of tomatoes

The cost of the tomatoes for a number of packages = 4.45p

= 4.45(2 1/4)

= 4.45(9/4)

= 4.45(2.25)

= $10.0125

In conclusion, the variable p represent pounds of tomatoes sold in the store.

Step-by-step explanation:

Where m is the slope and b is the y-intercept.

Subtract 3x from both sides,

           4y = -3x + 64

Now, divide both sides by 4,

The surface area and the volume of solid prism are 432in² and 576in³ respectively.

A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles

The surface area of a rectangular prism is expressed as;

A = 2( wl + hl + hw )

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length.

Given the data in the question;

The surface area of the solid is;

A = 2( wl + hl + hw )

A = 2( (8in × 12in) + (6in × 12in) + (6in × 8in) )

A = 2( 96in² + 72in² + 48in² )

A = 2( 216in² )

A = 432in²

Therefore, surface area of the rectangular prism is 432in²

The volume of the solid is;

V = w × h × l

V = 8in × 6in × 12in

V = 576in³

Therefore, volume of the rectangular prism is 576in³

Standard deviation of population mean is 0.33.

Why is there a standard deviation?

it is shown that 5% values are over 2.1 pounds and 5% are under 1.9 pounds

so stastically that means

P( X > 2.1,  μ; σ) = 0.05 and P( X 1.9; μ; σ) = 0.05

where  μ is mean of the sample and σis the standard deviation of the sample.

so mean can be calculated easily μ = (2.1 + 1.9)/2 = 2.0

and as we can interpret P(1.9 <x < 2.1; 2.0; σ) = 0.90 by normal distribution the Z value for 90% confidence interval is 1.65

so σ = (2.1 -2) /1.65 = 0.06

standard deviation of the sample mean= 0.06

and by that standard deviation of population mean = 0.06 * (30) 0.5  = 0.33

Answer:

A

Step-by-step explanation:

using the sine ratio and the exact values

sin30° = [tex]\frac{1}{2}[/tex] and sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

calculate the height of the wall below x , call it h

the hypotenuse is the length of the ladder

using the sine ratio in the lower right triangle.

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2h = 18 ( divide both sides by 2 )

h = 9

lower part of the wall is 9 meters

using the sine ratio in the right triangle on the right

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9+x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2(9 + x) = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

9 + x = 9[tex]\sqrt{3}[/tex] ( subtract 9 from both sides )

x = 9[tex]\sqrt{3}[/tex] - 9 = 9([tex]\sqrt{3}[/tex] - 1)

Answer:

[tex]\textsf{A)} \quad x=9(\sqrt{3}-1)[/tex]

Step-by-step explanation:

Interior angles of a triangle sum to 180°.  Therefore, if the ladder makes an angle of 30° with the ground, the angle it makes with the wall is 60°.

Therefore, the two triangles are congruent as their corresponding angles are the same and the length of their longest side (hypotenuse) is the same.

30-60-90 Triangle Theorem

A 30-60-90 triangle is a special right triangle where the measures of its angles are in the ratio 1 : 2 : 3 and the measure of its sides are in the ratio 1 : √3 : 2.

The formula for the sides is  b : b√3 : 2b  where:

Therefore, as the length of the hypotenuse is 18:

[tex]\implies 2b=18[/tex]

[tex]\implies b=9[/tex]

[tex]\implies b\sqrt{3}=9\sqrt{3}[/tex]

To find x, subtract the length of the shortest leg of the right triangle from the length of the other leg of the right triangle:

[tex]\implies x=9\sqrt{3}-9[/tex]

[tex]\implies x=9(\sqrt{3}-1)[/tex]

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Since 7 into 42 is six we know the answer can't be 7 because it's too high. We can also rule out 6 because 6 times 7.94 is more than 41. The first answer choice is wrong because if you take away the .94, 7 times 4 is 28 which is pretty far from 41. If you multiply 5 and 7, it comes out to 35. That's significantly closer than four.

There will  be no interval of time when Josue has more in savings than Arianna, they have same savings is after 4 weeks

Step one:

For Josue

initial savings balance= $70

weekly savings = $9

Let J represent amount of money Josue has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=9t+70-------1

For Arianna

initial savings balance= $30

weekly savings = $19

Let A represent the amount of money Arianna has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=19t+30---------2

Step two

equation 1 and 2 to find t

9t+70=19t+30

9t-19t=30-70

-10t=-40

divide both sides by 10

t=4

t=4 weeks

so after 4 weeks Josue and Arianna will have the same amount of money

For Josue t=4

J=9(4)+70-------1

J=36+70

J=$106

For Arianna t=4

A=19(4)+30---------2

A=76+30

A=$106

The two equations above shows that after 5 weeks their savings will be $106.

Answer:

(i) 7 + 4√2  cm^2.

(ii) 50 - 8√2  cm^2.

Step-by-step explanation:

(i)

Area = (3 + √8)(5 - 4/√2)

= 3(5 - 4/√2) + √8(5 - 4/√2)

= 15 - 12/√2 + 5√8 - 4√4

= 15 - 8 -( 12√2)/2 + 5*(2√2)

= 7 - 6√2 + 10√2

= 7 + 4√2.

(ii)

Area of the square

= AC^2

= (3 + √8)^2 + (5 - 4/√2)^2            (By Pythagoras)

= 9 + 6√8 + 8 + 25 - 40/√2 + 16/2

= 9 + 8 + 8 + 25 + 12√2 - 20√2

= 50 - 8√2.

The measure of m∠ABD in the figure shown is 19°.

Given:

∠BCD = 71°

In the figure, ΔABC is an isosceles triangle where AB = BC.

According to the Isosceles Triangle Theorem, an isosceles triangle has equal angles on either side of its equal sides.

So, ∠BAD = ∠BCD = 71°

The sum of angles in a triangle sums to 180°.

∠ABC + ∠BAD + ∠BCD = 180°

∠ABC + 71° + 71° = 180°

∠ABC + 142° = 180°

∠ABC = 180° - 142° = 38°

DB is the angle bisector of ∠ABC.

Now, ∠ABD = ∠CBD = 38°/2 = 19°

The measure of ∠ABD is 19°.
