Answer:

111.1

Step-by-step explanation:

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Distributive property which is expressed as

[tex]a\times (b+c)\\\\=a\times b+a\times c[/tex]

Similarly, in option 'A', we have

(0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) ​

Here, a = 0.5,

b= 0.5

c = 0.3

d = 0.2

So, it can be expressed as

[tex]a\times (b+c+d)=a\times b+a\times c+a\times d[/tex]

Hence, Option 'A' is correct.

Answer:Its B

1/6  is the gravitational force (in Newtons) that the Earth exerts on him when he's standing on the moon.

The gravitational force is a force that attracts any two gadgets with mass. We name the gravitational force attractive as it always tries to pull masses together, it in no way pushes them apart. In fact, every item, consisting of you, is pulling on every different item in the entire universe.

Final answer:

There are 30 students in total, 12 of whom play an instrument, and 25 of whom play a sport.

Explanation:

The question asks about the number of students who play an instrument and the number who play a sport. There are 30 students in total.

To find the number of students who play an instrument, we multiply 30 by ⅓ (2/5), since 2/5 of the students play an instrument. To find the number of students who play a sport, we multiply 30 by ⅕ (5/6), since 5/6 of the students play a sport.

For the instrument calculation: 30 × 2/5 = 12, so 12 students play an instrument.

For the sport calculation: 30 × 5/6 = 25, so 25 students play a sport.

Answer:

(A) Angles in equilateral triangle are congruent

Step-by-step explanation:

From the figure, it can be seen that in triangle ABD, [tex]AB=BD=AD[/tex] which means that all the sides of the triangle are congruent and by the definition of equilateral triangle, ΔABD will be an equilateral triangle.

Therefore, Using the property that Angles in equilateral triangle are congruent, we can find the value of x.

Thus, option A is correct.

An algebraic expression with a quotient of [tex]x^{5}[/tex] is [tex]\frac{x^{7} }{x^{2} }[/tex] and An algebraic expression with a product of [tex]x^{5}[/tex] is [tex]x^{3}\times x^{2}[/tex].

We need to write two algebraic expressions, one with a quotient of [tex]x^{5}[/tex] and one with a product of [tex]x^{5}[/tex].

An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.

Now, an algebraic expression with a quotient of [tex]x^{5}[/tex] is

[tex]\frac{x^{7} }{x^{2} } =x^{7-2}=x^{5}[/tex]  (∵[tex]\frac{a^{m} }{a^{n} } =a^{m-n}[/tex])

An algebraic expression with a product of [tex]x^{5}[/tex] is

[tex]x^{3}\times x^{2} = x^{3+2}=x^{5}[/tex]

Therefore, an algebraic expression with a quotient of [tex]x^{5}[/tex] is [tex]\frac{x^{7} }{x^{2} }[/tex] and An algebraic expression with a product of [tex]x^{5}[/tex] is [tex]x^{3}\times x^{2}[/tex].

1 quart = 2 pints

720/2 = 360 quarts per hour

1 hour = 60 minutes

360/60 = 6 quarts per minute

To convert 720 pints per hour to quarts per minute, divide the number of pints (720) by 2 to get quarts per hour (360), then divide by 60 minutes to find quarts per minute, resulting in 6 quarts per minute.

To convert 720 pints (pt) per hour to quarts (qt) per minute, first, we need to understand the relationship between pints and quarts. 1 quart is equal to 2 pints.

Therefore, to convert pints to quarts, we would divide the number of pints by 2. We also need to convert from per hour to per minute. Since there are 60 minutes in an hour, we divide the per-hour quantity by 60 to find the per-minute quantity.

Here's the step-by-step conversion:

Start with 720 pints per hour.

Since 1 quart is equal to 2 pints, divide 720 by 2 to convert to quarts. 720  2 = 360 quarts per hour.

To convert quarts per hour to quarts per minute, divide by 60 (since there are 60 minutes in an hour). 360   60 = 6 quarts per minute.

Therefore, 720 pints in an hour is equivalent to 6 quarts per minute.

Scale: 1 inch = 13 feet. 1.5 inches on the drawing. Actual length: 1.5 * 13 = 19.5 feet. Elephant length.

To find the actual length of the elephant, you need to use the scale provided by Maria's drawing. The scale states that 1 inch on the drawing represents 13 feet in reality. Since the elephant in the drawing is 1.5 inches long, we can calculate the actual length using the scale.

1. First, determine how many feet one inch on the drawing represents:

[tex]\( 1 \text{ inch on drawing} = 13 \text{ feet in reality} \)[/tex]

2. Multiply the number of inches in the drawing by the conversion factor to find the actual length:

 [tex]\( 1.5 \text{ inches on drawing} \times 13 \text{ feet/inch} = 19.5 \text{ feet in reality} \)[/tex]

So, the actual length of the elephant is 19.5 feet.
