find the area using 3.14 for π
round to the nearest Hundredth if you have too

Answer:

$840

Step-by-step explanation:

Given data

The cost of material is $315

The ratio is

3:4:1

The total number of part is

3+4+1= 8

Let us apply the part to all method

let the total cost be x

hence

3/8=315/x

cross multiply

3x= 8*315

3x= 2520

divide both sides by 3

x= 2520/3

x= $840

Hence the total money is $840

Answer:

∡1 = 82°

Step-by-step explanation:

The sum of the angles of a triangle is 180°.

You could find the missing angle by the following steps:

49° + 49° + x = 180°

x is the missing angle ∡1. Simplify the like terms.

98° + x = 180°

Bring 98° to the other side: makes it -98. This is done to find the value of x.

x = 180° - 98°

x = 82°

Answer:

[tex]sin(A - B) = \frac{4}{5}[/tex]

Step-by-step explanation:

Given:

[tex]sin(A) = \frac{24}{25}[/tex]

[tex]sin(B) = -\frac{4}{5}[/tex]

Need:

[tex]sin(A - B)[/tex]

First, let's look at the identities:

sum: [tex]sin(A + B) = sinAcosB + cosAsinB[/tex]

difference: [tex]sin(A - B) = sinAcosB - cosAsinB[/tex]

The question asks to find sin(A - B); therefore, we need to use the difference identity.

Based on the given information (value and quadrant), we can draw reference triangles to find the simplified values of A and B.

sin(A) = [tex]\frac{24}{25}[/tex]

cos(A) = [tex]\frac{7}{25}[/tex]

sin(B) = [tex]-\frac{4}{5}[/tex]

cos(B) = [tex]\frac{3}{5}[/tex]

Plug these values into the difference identity formula.

[tex]sin(A - B) = sinAcosB - cosAsinB[/tex]

[tex]sin(A - B) = (\frac{24}{25})(\frac{3}{5}) - (-\frac{4}{5})(\frac{7}{25})[/tex]

Multiply.

[tex]sin(A - B) = (\frac{72}{125}) + (\frac{28}{125})[/tex]

Add.

[tex]sin(A - B) = \frac{4}{5}[/tex]

This is your answer.

Hope this helps!

[tex]\implies \mathsf {sin (A - B) = \frac{100}{125} = \frac{4}{5} }[/tex]

Answer:

y= 3- x/3

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9−3x so it becomes x=9−3y.

Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)

Answer:

y=(-x/3)+3

Step-by-step explanation:

y=-3x+9

x=-3y+9

x-9=-3y, next division

(x-9)/-3=y

simply and rearrange

y=(-x/3)+3

circumference of circle is. 2π r

2π r = 24

2 * 22/7 * r = 24

r= 24 *7/2*22

r = 3.81

hope it helps

Answer: 3.8

Step-by-step explanation:

The formula for the circumference of a circle is dπ.

Because you want to find the radius you would have to divide the circumference by π.

24/π=7.639437268 this is the diameter.

To find the radius then you have to half it.

Half of 7.639437268 is 3.8 (1 decimal place).

The school can expect to raise approximately £85.71 for charity if 60 people played the game.

If each player pays 30p to play the game, and 60 people played the game, the total amount raised by the school would be:

Total amount raised = Number of players * Cost per player

Total amount raised = 60 * 30p

Now, let's calculate the cost of the crisps won by the players:

Cost of crisps won = Number of crisps won * Cost per crisp

Since each bag of crisps costs 20p, and players have to score exactly 7 to win a bag of crisps, we need to determine the number of bags of crisps won.

To find the number of bags of crisps won, we divide the total number of players by the number of players required to win a bag of crisps:

Number of bags of crisps won = Number of players / Number of players required to win a bag of crisps

Number of bags of crisps won = 60 / 7

Now, we can calculate the cost of the crisps won:

Cost of crisps won = Number of bags of crisps won * Cost per crisp

Cost of crisps won = (60 / 7) * 20p

Finally, to determine the amount the school expects to raise for charity, we subtract the cost of the crisps won from the total amount raised:

Amount raised for charity = Total amount raised - Cost of crisps won

Amount raised for charity = 60 * 30p - (60 / 7) * 20p

To simplify the calculation, we can convert the pence to pounds by dividing by 100:

Amount raised for charity = (60 * 30) - (60 / 7) * 20 = £(1800 - (1714.2857))

Amount raised for charity ≈ £85.71 (rounded to two decimal places)

Therefore, the school can expect to raise approximately £85.71 for charity if 60 people played the game.

Answer:

Single Equivalent Discount % on final price  = 41.58%

Explanation:

The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100

and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.

but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:

((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.

Answer:

$1.33

Step-by-step explanation:

If 3 apple cost $4. Then the cost of one apple will be $1.33 per apple.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

If 3 apple cost $4.

Then the cost of the one apple will be given by the quotient of 4 and 3.

Then the price of one apple will be

⇒ $4/3

⇒$1.33 per apple

Thus, the cost of one apple will be $1.33 per apple.

Answer:

A burrito costs $8, while a taco costs $6.

Step-by-step explanation:

Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:

3B + 4T = 48

3B = 48 - 4T

6B + 2T = 60

6B = 60 - 2T

3B = 30 - 1T

30 - 1T = 48 - 4T

30 = 48 - 4T + 1T

30 - 48 = -3T

-18 = -3T

-6 = -T

6 = T

3B + 4x6 = 48

3B + 24 = 48

3B = 24

B = 24/8

B = 8

6x8 + 2x6 = 60

48 + 12 = 60

60 = 60

Thus, a burrito costs $ 8, while a taco costs $ 6.
