Step-by-step explanation:

cosθ  = 8/10

θ = arcCos(8/10)

θ  =36.87

cot(36.87) = 8/x

1.33 = 8/x

x1.33 = 8

x = 6

Answer:

the height forms a right triangle with the slant height as the hypotenuse and half of the base diagonal as the other leg

(height)^2 = (slant height)^2 - (half of base diagonal)^2

h^2 = 83.3^2 - (10.8 √2)^2

Answer:

Ingredient Percentage=Ingredient Weight/Total Flour x 100%

Step-by-step explanation:

For example, if a formula calls for 60 pounds of water and 100 pounds of flour, the baker's percent would be 60% water. If there are two types of flour being used, the combination of the weight of both flours will be 100%.

Answer:

length = 9 cm

Step-by-step explanation:

perimeter = p =26 cm

width = w=  4 cm

perimeter of a rectangle= 2*w+2*L

L= length

so we have:

26 = 2*(4) +2*L

26= 8 +2L

26-8 = 2L

18 = 2L

L= 18/2

L =9 cm = length

Answer:

$ 1.725

Step-by-step explanation:

4 Pack of coffee = $ 6.90

1 Pack of coffee = $ 6.90 / 4 = $ 1.725

( The word per means " 1 " )

Answer:

$1.73

Step-by-step explanation:

To get the price of one bottle, set up a proportion.

let x = the price of one bottle

the numerator will be the price of the bottles and the denominator will be the number of bottles.

6.90 / 4  = x / 1

cross multiply: 6.90 = 4x

solve for x by dividing by 4 on both sides

6.90/4 = 4x / 4

x = 1.725, round up to $1.73

Answer: [tex]x < 8\\[/tex]

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Interval Notation: (-∞, 8)

The equivalent inequality to 5(2x-6)+6(3-x)<2x+4 is x < 8.

Let's simplify the given inequality step by step:

Original inequality: 5(2x - 6) + 6(3 - x) < 2x + 4

Distribute the constants inside the parentheses:

10x - 30 + 18 - 6x < 2x + 4

Combine like terms on the left side:

(10x - 6x) - 30 + 18 < 2x + 4

4x - 12 < 2x + 4

Subtract 2x from both sides to isolate the x terms on the left side:

4x - 2x - 12 < 4

Simplify:

2x - 12 < 4

Now, add 12 to both sides:

2x - 12 + 12 < 4 + 12

2x < 16

Finally, divide both sides by 2:

2x / 2 < 16 / 2

x < 8

Answer:

[tex]\huge\purple{ x^2 +(y+2)^2 = 4}[/tex]

Step-by-step explanation:

Circle is centred at (0, -2)

-> h = 0 & k = - 2

radius of the circle (r) = y-coordinate of the center = - 2

Equation of circle in standard form is given as:

[tex](x-h)^2 +(y-k)^2 = r^2[/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex](x-0)^2 +[y-(-2)]^2 = (-2)^2[/tex]

[tex]\implies\huge\orange{ x^2 +(y+2)^2 = 4}[/tex]

This is the required equation of circle.

Number of females not enrolled

(a)

The table based on data is

                Enrolled        Not enrolled      Total  

Male            82                  36                     118

(b)

Percentage of students were males that went to magic college

(c)

Percentage of females went to magic college

Answer:

a)  see below

b)  29.7%  (1 d.p.)

c)  64.6%  (1 d.p.)

Step-by-step explanation:

Part (a)

Using the given information to create a two-way table:

[tex]\begin{array}{|l|c|c|c|}\cline{1-4} & \sf Female & \sf Male & \sf Totals\\\cline{1-4} \sf Enrolled & 102 & 82 & \\\cline{1-4} \sf Not\:enrolled & & &\\\cline{1-4} \sf Totals & 158 & & 278\\\cline{1-4}\end{array}[/tex]

Calculations to fill the table:

Therefore:

[tex]\begin{array}{|l|c|c|c|}\cline{1-4} & \sf Female & \sf Male & \sf Totals\\\cline{1-4} \sf Enrolled & 102 & 82 & 184 \\\cline{1-4} \sf Not\:enrolled & 56 & 38& 94 \\\cline{1-4} \sf Totals & 158 &120 & 278\\\cline{1-4}\end{array}[/tex]

Part (b)

[tex]\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100[/tex]

Number of students who are male and enrolled = 82

Total number of students = 278

[tex]\begin{aligned} \implies \sf Percentage\:students\:enrolled & = \sf\left(\dfrac{82}{278}\right) \times 100\\& = \sf 29.7\%\:\:(1\:d.p.) \end{aligned}[/tex]

Part (c)

Total number of females enrolled = 102

Total number of females = 158

[tex]\begin{aligned} \implies \sf Percentage\:students\:enrolled & = \sf\left(\dfrac{102}{158}\right) \times 100\\& = \sf 64.6\%\:\:(1\:d.p.) \end{aligned}[/tex]

The distance between two parallel lines  y=x+3 and y=x+1 will be equal to

[tex]d=\dfrac{1}{\sqrt{2}}[/tex]

The lines which do not intersect to each other and only intersect at infinity are called parallel lines.

Here we have two lines:-

y=x+3

y=x+1

The formula for the distance between two parallel lines is given by:-

[tex]d=\dfrac{|C_1-C_2|}{\sqrt{a^2+b^2}}[/tex]

We have C1=3 C2=1 a=1 b=1 by putting the value in the formula we will get:-

[tex]d=\dfrac{3-2}{\sqrt{1^2+1^2}}=\dfrac{1}{\sqrt{2}}[/tex]

Hence distance between two parallel lines  y=x+3 and y=x+1 will be equal to  [tex]d=\dfrac{1}{\sqrt{2}}[/tex]

Answer:  30 students: $346.5

1 student: $11.55

Step-by-step explanation:

The total cost in dollars for admission and lunch for 30 students is $406.6 and for each student is $13.55.

The unitary method is a technique for solving a problem by first finding the value of single unit, and then finding the value the necessary value by multiplying the single unit.

According to the given question

Cost price for five students for taking admission to the museum and lunch is 36.25 and 31.50 respectively.

cost price for one student for taking admission in museum = [tex]\frac{36.25}{5} = $7.25[/tex]

cost price for one student lunch = [tex]\frac{31.50}{5} = 6.3[/tex]

Therefore,

The total cost for each student for the admission and lunch = 7.25+6.3 =

$13.55

And, the total cost for 30 students for admission and lunch = 30×$13.55 =$406.5

Hence, the total cost for admission to museum and lunch for each student is $13.55 and for 30 students is $406.6.

Renewable energy is energy that comes from a source that won't run out. They are natural and self-replenishing and usually have a low- or zero-carbon footprint.

Now, Renewable energy sources have numerous advantages, such as being environmentally friendly and sustainable, one of the disadvantages is the initial high cost of transitioning from traditional energy sources to renewable ones.

Since renewable energy sources do not create large amounts of pollution.

Additionally, renewable energy has the potential to produce ample power to meet our needs.

Finally, the fact that renewable energy will not run out is actually an advantage, not a disadvantage.

Explanation:

1 gallon = 4 quarts

2 gallons = 8 quarts

1/4 of 8 quarts = 2 quarts

She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.

That leaves 8 - 5 = 3 quarts for the living room.

Answer:

A: 3 Quarts

Step-by-step explanation:

1 gallon = 4 quarts

1/4 of 2 gallons = 1/4 × 2

                         = 1/2 gallon

⇒ 1/2 gallon = 2 quarts

Therefore, Mieko used 2 quarts of paint to paint her bedroom.

If she used 3 quarts to paint the hallway, then

⇒ total number of quarts used = 2 + 3 = 5 quarts

As she bought a total of 2 gallons of paint:

⇒ 2 gallons = 2 × 4 = 8 quarts

Therefore the remaining unused paint (to paint the living room) is:

⇒ total paint - used paid = 8 quarts - 5 quarts

                                         = 3 quarts
