What angle do the minute and hour hands of a clock make at 10:00

Answers

Answer 1
Answer: The hour hand is at 10 and the minute at the 12. If a clock is seen divided into 12 parts and there's 360° in a circle so 360/12=30° between two numbers.
Between 10 and 11 is 30°, between 11 and 12 is 30° so between 10 and 12 is 60°

Answers

The simplified expression is: (3/2) x⁵ * (1/y⁴), or (3x⁵) /(2y⁴).

What is indices?

Indices, in mathematics, refer to the small numbers or symbols (exponents) used to indicate the power or exponent to which a number is raised, often in the context of exponents or powers.

To divide the expression (21x⁶y⁵) by (14x¹y⁹), simplify by subtracting the exponents of like terms:

(21x⁶y⁵) / (14x¹y⁹) = (21/14) * (x⁶⁻¹ * (y⁵⁻⁹))

Now simplify each part:

121/14) simplifies to (3/2)

x⁶⁻¹ simplifies to x⁵

3. y⁵⁻⁹ simplifies to y⁻⁴

So, the simplified expression is

(3/2) x⁵ * (1/y⁴), or (3x⁵) / (2y⁴).

A parallelogram has a base of 16 inches and a height of 11.7 inches. What is the area of the parallelogram?

Answers

Answer:

A = 187.2 inches²

Step-by-step explanation:

the area (A) of a parallelogram is calculated as

A = base × height

substitute base = 16 inches and height = 11.7 inches into the formula for A

A = 16 × 11.7 = 187.2 inches²

Jen bought some sesame bagels and some plain bagels. The ratio of the numbers of sesame bagels to the number of plain bagels is 1:3 .A. What is the fraction of the bagels that are plain.
B.What percent of the bagels are plain.
C.If Jill bought 2 dozen bagels,how many of each type of bagel did she buy.

Answers

A. What is the fraction of the bagels that are plain?

Sesame bagels: plain bagels = 1 : 3
This means that 1/3 of the bagels are sesame.
Therefore, you know that 2/3 of the bagels are plain, as Jen bought only these two types of bagels.

B.  What percent of the bagels are plain?

From Part A, we know that 2/3 of the bagels are plain.  To find the decimal approximation, we just divide the numerator by the denominator.

2/3 ≈ 0.67

0.67 as a percentage is 67%.

Therefore, 67% of the bagels are plain.

C. If Jen bought two dozen bagels, how many of each type of bagel did she buy?

We know that a dozen bagels is 12 bagels.
Because Jen bought two dozen bagels, she has 24 total bagels.

We know that the ratio of sesame to plain bagels is 1:3.
We set up an equation to model this ratio, letting x represent the number of unknown bagels.

1x + 3x = 24

When we combine like terms, we get the equation:
4x=24

When we divide both sides by 4, we get our answer:

x=6

Now we substitute our known variable back into the equation for x.

1(6) = sesame 
3(6) = plain
Together, these amounts equal 24 bagels.
After multiplying, we find out that Jen bought a total of 6 sesame bagels and 18 plain bagels.

How long is 63 months in years?

Answers

The time-duration "63-months" in years can be expressed as 5.25 years.

To determine the length of 63 months in years, we divide 63 by the number of months in a year, which is 12.

Dividing 63 by 12 yields a quotient of 5 with a remainder of 3.

This means that 63 months is equivalent to 5 years and 3 months.

To express it completely in years, we consider the fraction of the year represented by the remaining 3 months.

Since there are 12 months in a year, 3 months is equivalent to 3/12 which 1/4 of a year = 0.25 year.

Therefore, 63 months is approximately 5.25 years.
