find the angle measure indicated

Answer:

A = 10W - W²

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Area of a rectangle =LW

L is the length

W is the width

Given

Perimeter = 20m

20 = 2 (L+W)

10 = L+W

L = 10 - W ....2

Substitute equation 2 into the formula for calculating the area

Recall that A = LW

A = (10-W)W

A = 10W - W²

Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

The fraction -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5

The integer part of a mixed number is the whole number portion, while the fractional part is the remaining fraction.

In this case, the integer part of -9 4/5 is -9, and the fractional part is 4/5.

To express the mixed number as the sum of its integer and fractional parts, we simply add the integer and the fraction:

So, we have

-9 + 4/5

When evaluated, we get

-9 + 4/5 = -45/5 + 4/5 = -41/5

Therefore, -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5 = -41/5.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The total cost of the pair of headphones is $23.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/200 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

105 = 10/100 = 1/10

We have,

Original price of the headphones = $50

60% of $50

= 60/100 x 50

= $30

The price of the headphones after the discount.

= $50 - $20

= $20

The amount of sales tax.

= 15% of $20

= 15/100 x 20

= $3

The total cost.

= $20 + $3

= $23

Thus,

The total cost of the pair of headphones is $23.

The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.

Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.

We have data shown in the table:

Total number of T-shirts = 200+300+400+300 = 1200

As there are only 400 T-shirts left it means,

So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.

200 T-shirts left in the June stock

Out of 300, there are 200 T-shirts left in the month of July.

Cost for 200 T-shirts = 200×8 = $1600

Cost for 200 T-shirts = 200×10 = $2000

Total cost = 1600+2000

= $3600

Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

Answer: -4 1/3, -1/6, 5/6, 4 1/3

Step-by-step explanation:

To the left of the number line we would have the negatives which are -4 1/3, and -1/6. Then, to the right we have 5/6 and 4 1/3 because they are positives. That's the order they would go in from left to right on the number line.

Answer:

In order of least to greatest:

-2 1/2, -3/8, 7/8, 2 1/2

Step-by-step explanation:

First, we look at the negatives. Which one is the bigger number -2 1/2 or -3/8?

-3/8 is the bigger number, making the negative order on the left -2 1/2, -3/8.

Now we look at the positives. Which one is bigger, 7/8 or 2 1/2? 2 1/2 is the bigger number. Meaning the right side of the number line should look like 7/8, 2 1/2.

All together we get -2 1/2, -3/8, 7/8, 2 1/2

Answer:

5.3 inches

Step-by-step explanation:

The diagonal of a rectangle frame is 8 inches and the width of the frame is 6 inches. What is the length of this frame in inches?

Diagonal² = Length² + Width²

Length = √Diagonal² - Width

= √8² - 6²

= √64 - 36

= √(28)

Length = 5.2915026221 inches

Approximately = 5.3 Inches

Answer:

147.03cm

Step-by-step explanation:

A parallelogram is just a tilted rectangle, so it uses the same formula, base times height.

This would be 8.7 × 16.9

 87 × 169 = 14703

move the decimal to get

8.7 × 16.9 = 147.03

The right answer is "5.9". A further solving is provided below.

Step-by-step explanation:

The given values are:

Initial Magnitude,

M₁ = 3.9

Let Second magnitude be M₂.

Now,

⇒  [tex]M_2-M_1=log(\frac{l_2}{l_1} )[/tex]

On substituting the values, we get

⇒  [tex]M_2-3.9 = log (120)[/tex]

On putting the value of "log 120", we get

⇒  [tex]M_2-3.9=2.079[/tex]

On adding "3.9" both sides, we get

⇒  [tex]M_2-3.9+3.9=2.079+3.9[/tex]

Answer:

13

Step-by-step explanation:

To solve the problem, you have to do A squared + B squared = C squared. So for your A and B it doesn't matter what order you put them in. We will do 12 sqaured + 5 squared = C squared. 12 squared is 144 and 5 squared is 25. By adding 144 and 25 together, it gives us 169. When we take the square root of 169, we get 13. 13 is the length of the hypotenuse.
