Question 7
Which radical expression consists of two perfect squares?
A
V16
B
V25
С
125
D
V21

Answers

Answer:

A. √16

Step-by-step explanation:

A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.

From the options given, the only radical expression that has two perfect square is √16.

√16 consists of two perfect squares, which are 4 and 4.

4 can be expressed as 2 × 2.

Thus: √16 = √(2 × 2)(2 × 2).

Therefore, √16 consists of two perfect squares.

If the pattern shown continues how many black keys appear on a keyboard with 35 white keys ?

Answers

Answer:

25 black keys

Step-by-step explanation:

Let the number of requires black keys = 'x'

White key : Black keys = 7 : 5

7 : 5  :: 35 : x

Product of extremes = product of means

             7 *x = 35 * 5

                  x = [tex]\frac{35*5}{7}[/tex]

                 x = 5 *5

                 x = 25

A line passes through the points (8, 1) and (6, 7). What is the slope?



Answers

Answer:

-3

Step-by-step explanation:

7-1=6

6-8=-2

A line connects the points (8, 1) and (6, 7). The angle is -3.

What is meant by slope?The slope or slope of a line is a number in mathematics that describes both the direction and slope of a line. Gradients are frequently represented by the letter m.There is no clear reason why the letter m is used for gradients, but it was first used in English by O'Brien (1844), who wrote the equation for a straight line as "y = mx + b."He is also depicted in Tod Hunter's (1888) work, where he wrote "y = mx + c."The slope is calculated by dividing the difference between two (arbitrary) points on a line by the ratio of vertical and horizontal change.

Therefore,

Slope (m) = ΔY/ΔX

= 3/-1

= -3

The slope =  -3

θ = arctan(ΔY/ΔX) + 180°

=1 08.43494882292°

ΔX = 6 – 8 = -2

ΔY = 7 – 1 = 6

Distance (d) = √ΔX2 + ΔY2 = √40 = 6.3245553203368

Equation of the line:

y = -3x + 25

When x = 0, y = 25

When y = 0, x = 8.3333333333333

Hence,  A line connects the points (8, 1) and (6, 7). The angle is -3.

If f(x) is a density function, then its integral over the entire real line should be 1:

There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both. How many people had swim suits on but not sunglasses, if you know 38 have swim suits on and 25 have sunglasses?
1. 35.
2. 49.
3. 41.

Answers

Given :

There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both.

38 have swim suits on and 25 have sunglasses.

To Find :

How many people had swim suits on but not sunglasses.

Solution :

Let, A refer swim suits and B refer sunglasses.

∞∪∩

A ∪ B = 50

A = 38

B =  25

We need to find, A - (A ∩ B) .

We know,

(A ∩ B) = A + B - (A ∪ B)

(A ∩ B) = 38 + 25 - 50

(A ∩ B) = 13

So, A - (A ∩ B) = 38 - 13 = 25

Therefore, number of people with swim suits on but not sunglasses are 25.

Answers

Answer: x=25

Step-by-step explanation:  

This is mainly algebraic calculations, so it's just using operations. You can open the parentheses in any order you want, but I started with the numerator of the first expression. I simplified it to get 3.8-3.3, which is the same as 0.5 Then I moved on to the denominator of the second equation. Distribute the 0.8, then add it to 3.2, getting 5. The numerator is a bit trickier. There's a lot of LCMs to find, but first multiply 5/66 by 2 1/2. You can use the butterfly method to simplify it, and get 1/33. Use LCMs to subtract the 3 fractions, getting a result of 1/12. Using cross multiplication, you get the result of x=25.

Ajay left x and y at 9 am.At the same time bala left y and x.After their meeting at a point on the way.Ajay took 16 minutes to reach y and bala took 9 minutes to reach x .Find the meeting time?
​

Answers

Answer:

9:12 am

Step-by-step explanation:

Let the time Ajay and Bala took to meet be t, speed of Ajay be a and speed of Bala be b

Until they met, the distance they made:

Ajay ⇒  at  Bala ⇒  bt

Now, the rest of the distance took Ajay 16 min and Bala 9 min.  

We can compare the distances as:

16a = bt9b = at

From the first equation we have:

a/b = t/16

From the second equation we have:

a/b = 9/t

Comparing:

t/16= 9/tt² = 9*16t² = 144t = √144t = 12 min

The meting time is:

9:00 am + 12 min = 9:12 am

if mrs. Rios washed 1/4 f her laundry and her son washed 2/5 so Who washed most of the laundry? How much of the laundry still needs to be washed?

Answers

Answer:

7/20 still needs to be washed.

Step-by-step explanation:

You will need to find the lowest common multiple and add the two fractions together and subtract that sum from 1. The 1 represents the total amount of laundry and the sum you will find represents the fraction of laundry that Mrs. Rios and her son have already washed combined.    

1/4 + 2/5

= 5/20 + 8/20

= 13/20

1 - 13/20

= 20/20 - 13/20

= 7/20

Mrs. Rios son washed more clothes and her son washed 3/20 fraction of more clothes.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, If Mrs. Rios washed 1/4 f her laundry and her son washed 2/5.

Now, The LCM of 4 and 5 is 20.

So,  Mrs. Rios washed (1×5)/20 = 5/20 and her son washed

2×4/20 = 8/20.

So, Her son washed more clothes and her son washed 8/20 - 5/20 = 3/20 fraction of more clothes.
