Answer:

B is correct.

Answer:

40

Step-by-step explanation:

AREA=LW

L₁W₁=40

L₂W₂=160

x(L₁W₁)=L₂W₂

x(L₁W₁)=L₂W₂

x(40)=160

x=40

Answer: 20x

expalnation: Not sure about the second one  but the first problem is a trick problem your finding the mean. but it already brought the equation down to 1 so 20 is the answer

Answer:

.625

Step-by-step explanation:

Since the amount of pieces are 8, and you gave 5 away, you have to divide 5 by 8. This gives you .625

Answer:

Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Step-by-step explanation:

Given that Ron paid X dollars for a pair of jeans, and Tim bought the same pair of jeans for half the price as Ron, if they paid a total of $ 45 for the 2 pairs, to determine how much did each spend on their jeans you must perform the following calculation:

X + 1 / 2X = 45

1X + 0.5X = 45

1.5X = 45

X = 45 / 1.5

X = 30

So Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Answer:

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius

= 2×2

= 4cm

Answer:

The coat originally cost $20.

Step-by-step explanation:

The original cost is of x.

At a sale, coats were sold for $11 each. This price was 55% of a coat's original price.

This meas that:

[tex]0.55x = 11[/tex]

How much did a coat originally cost?

This is the solution for x for the equation above. So

[tex]x = \frac{11}{0.55} = 20[/tex]

The coat originally cost $20.

Answer:

20

Step-by-step explanation:

so when setting up you put 11/x=55/100 then cross multiply. then you should get 55x=1,100 .

divide 1,100 by 55 then you should get your answer which is

x=20 :)

Answer:

Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.

Step-by-step explanation:

The value of two consecutive odd positive integers are 5 and 6.

What are Integers?

A whole that can be positive , negative and zero is called integers.

Given that;

The product of two integers is 23 more that their sum.

Let two consecutive odd positive integers are x and x + 2.

Now, By the given condition we can formulate;

x (x + 2) = 23 + x + (x + 2)

x² + 2x = 23 + 2x + 2

x² + 2x = 25 + 2x

x² = 25

Take square root;

x = √25

x = ± 5

Since, Numbers are positive.

So, x = 5

And x + 1 = 5 + 1 = 6

Thus, The value of two consecutive odd positive integers are 5 and 6.

#SPJ2

Answer:

Step-by-step explanation:

If there is a character you cannot type, such as θ, you are better off substituting a different letter, or describing it in words. For example, write it as "sinA" or "sin(theta)"

Never use 0 as a substitute for θ! 0 is a constant with a specific value.

Since the argument of the trig functions is an expression, you should put parentheses around it:  sin(2A).

:::::

I used several trigonometric identities for this question:

Double-angle formula for sine: sin(2θ) = 2sinθcosθ

Double-angle formula for tangent: tan(2θ) = 2tanθ/(1-tan²θ)

Quotient identity: tanθ = sinθ/cosθ 

Reciprocal identity: secθ = 1/cosθ

Pythagorean identity: 1+tan²θ = sec²θ

2sin(2θ) - tan(2θ) = 0

2sin(2θ) = tan(2θ)

2·2sinθcosθ = 2tanθ/(1-tan²θ)

2sinθcosθ = tanθ/(1-tan²θ)

2sinθcosθ = (sinθ/cosθ ) · 1/(cosθ(1-tan²θ))

2(1-tan²θ) = 1/cos²θ

2(1-tan²θ) = sec²θ

2-2tan²θ) = 1+tan²θ

1 = 3tan²θ

tan²θ = ⅓

tanθ = ±1/√3

θ = 30°, 330°

Answer:

m = -4/3 b = 0

Step-by-step explanation:

Slope formula is [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

[tex]\frac{-4-0=-4}{3-0=3}[/tex]

The slope is -4/3. The line intersects the y-axis at (0 , 0) so b = 0. This can be verified by plugging one of the points into the equation.

I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)

Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.

Answer:

(15n^2-5n+45)/5

=3n^2-n+9

Answer:

3n^2-n+9

Step-by-step explanation:

You would want to divide the 5 between each of the terms. 15n^2 ÷ 5 is 3n^2. 15 ÷ 5 is 3. The n^2 stays, so 3n^2. -5 ÷ 5 is -1. We don't have to worry about writing the -1. Rather, just write the -n, it is the same as writing -1n. Lastly, 45 ÷ 5 is 9. You have to put the terms together in standard form. Standard form is just writing the numbers from greatest power to least power. The 3n^2 would come first since 2 is the greatest power. Next would be the -n, and lastly the 9. The 9 is the constant, which always comes last. A constant would be a number without a variable after it, like 2x is not a constant but just 2 is. Therefore, the answer is 3n^2-n+9.

Answer:

Area = 32

Step-by-step explanation:

Remark

The standard area for a Triangle is

Area = 1/2 * b * h

Givens

b = 16

k = 1/2

h = 4

Solution

Area = 1/2 * b * h

Area = 1/2 * 16 * 4

Area = 32
