Answer:

9D +6C < 108

Step-by-step explanation:

Let the price of Dvd be D

Let the price of CDs be C

Hence the inequality can be represented as follows

9D + 6C < 108

Answer:

B. 5√2

Step-by-step explanation:

hey, simply use Pythagoras theorem.

h²=p²+b²

or, 10²=x²+x²

or, 100= 2x²

or, x²=50

or, x= √50

or, x= √25×√2=5√2

Answer:

A, 120.

Step-by-step explanation:

x-15+75=180

x+60=180

x=120.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬

→ Base = 15 and 10

→ Height = 12

→ Area of trapezoid

→ Area of Trapezoid = (a + b)/2 × h

= (15 + 10)/2 × 12

= 150 ft²

∴ The area of Trapezoid is 150 ft²

Answer:

There are 406 students in the school

Step-by-step explanation:

Let the number of students in the school be x

The total ratio is 11 + 3 = 14

The ratio that buys lunch is represented by 3

So, we have it that;

3/14 * x = 87

3x = (14 * 87)

x = (14 * 87)/3

x = 406

Answer:

The correct answer is A. $729.98.

Step-by-step explanation:

Given that the purchase price for a house is $ 309,900, to determine what is the monthly payment if you put 20% down for a 30 year loan with a fixed rate of 6%, the following calculation must be performed:

100 - 20 = 80

(309,900 x 0.80) x 1.06 / (30x12) = X

247,920 x 1.06 / 360 = X

262,795.2 / 360 = X

729.98 = X

Therefore, the monthly payments will be $ 729.98.

Answer:

Monthly Payment = 1,486.41

Answer:

-36

Step-by-step explanation:

replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144.  So then you would take -144 and divide it by 4 and your answer would be -36.

Answer:

20

Step-by-step explanation:

First step is finding an angle in the rightmost triangle (angle K)

Using TOA we have

Tan(x)=4/8

x=26.565

which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle

Using this we can solve for JM

Tan(63.4349)=x/8

8tan(63.4349=x

x=16

So if JM = 16

and LM=4

take their sum to find JL

16+4=20

Answer:

the correct answer is option D

Answer:

#1:

cos a = opp/hyp = cb/ca

tan a = opp/ajd = cb/ab

sin c = adj/hyp = ab/ca

cos c = opp/hyp = ab/ca

tan c = opp/adj = ab/cb

2: *i dont have the square root symbol*

sin 60 = 3/2

cos 60 = x/2

tan 60 = 3/x

sin 30 = x/2

cos 30 = 3/2

tan 30 = x/3

3: *i dont have the square root symbol*

sin 45 = 2/x

cos 45 = x/2

tan 45 or 48 = x/y

Hello!

The answer is 28.8, When finding the Volume of a shape, you multiply all numbers.

Answer:

26

Step-by-step explanation:

The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.

90+64=154 and 180-154=26.

So 26 is your answer because 90+64+26=180

Answer:

35%

A percentage is a way of representing how much of a whole is present. Like a decimal or a fraction, a percentage is another form of showing these ratios and portions.

From the chart, we need to find how the total number of female students and the total number of male students.

Female

[tex]18+12=30[/tex]

Male

[tex]5+15=20[/tex]

First, take the number of female students that prefer pizza and divide it by the total number of female students.

[tex]\displaystyle \frac{18}{30}[/tex]

[tex]\displaystyle \frac{3}{5}[/tex]

Convert the fraction into a decimal by using a calculator.

[tex]\displaystyle \frac{3}{5} = 0.6[/tex]

Then, convert the decimal to a percentage by multiplying by 100.

[tex]0.6\times100=60\%[/tex]

The percentage of female students who preferred pizza is 60%.

Take the number of male students that prefer pizza and divide it by the total number of male students.

[tex]\displaystyle \frac{5}{20}[/tex]

[tex]\displaystyle \frac{1}{4}[/tex]

Convert the fraction into a decimal by using a calculator.

[tex]\displaystyle \frac{1}{4}=0.25[/tex]

Then, convert the decimal into a percentage by multiplying by 100.

[tex]0.25\times100=25\%[/tex]

The percentage of male students who preferred pizza is 25%.

Finally, subtract the percentage of male students who preferred pizza from the percentage of female students who preferred pizza.

[tex]60\%-25\%=35\%[/tex]

The final answer is 35%.
