Answer:

6

Step-by-step explanation:

1/2 = 0.5

2/5 = 0.4

60 × 0.5 = 30

60 × 0.4 = 24

30 + 24 = 54

60 - 54 = 6

Answer:

6

Step-by-step explanation:

Louis build 1/2 of the toy and the total of the toy is 60

Which means

1/2×60=30

Valentina build 2/5 toy

2/5×60

120/5

24

So to determine the amount left

It will be

Total-(Louis+Valentina)

60-(30+24)

60-(54)

60-54

6

So the amount left is 6

The rate of interest is 4% and this can be determined by using the formula of simple interest.

Given :

The formula of simple interest can be used in order to determine the rate of interest. The formula of simple interest is given by:

A = P(1 + rt)

where A is the final amount, r is the rate of interest, t is the time period in year and P is the principal amount.

Now, substitute the values of all the known terms in the above formula.

2295 = 2250(1 + 0.5r)

Simplify the above expression in order to determine the value of 'r'.

2295 = 2250 + 1125r

45 = 1125r

r = 0.04

r = 4%

The rate of interest is 4% and this can be determined by using the formula of simple interest.

Answer:

a = 9

b = 19

Step-by-step explanation:

DO B FIRST

The mean is the average of all the terms (numbers) in the sequence

To find the average you find the sum of the terms and divided the sum by the number of terms there are.

The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A

a = 17(10)-7-12-15-17-19-20-22-24-25

a = 170-161

a = 9

The median is found by taking the average of the two middle terms

Our middle terms are 17 and B

the median times 2 equals the sum of the two terms and then subtract the term you know from the sum

b = 18(2)-17

b = 36-17

b = 19

For 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.  

It is defined as the change in values of a dependent variable with respect to the independent variables.

W have:

Rate of burning for thicker = h/4

Rate of burning for thinner= h/2

remaining part = h - ht/4

remaining part = h - ht/2

h - ht/4 = 3(h - ht/2)

After solving for t:

t = 8/5 hours

or

t = 96 minutes

Thus, for 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.

Answer:

a. (-3, 2).

b.  √65

c.  (x + 3)^2 + (y - 2)^2 = 65

Step-by-step explanation:

a.  The center is the midpoint  of the diameter PQ.

= (-10+4)/2, (-2+6)/2

= (-3, 2).

b. The radius is the distance from the center to a point on the circle.

Take the point (4, 6):

The radius = √((-3-4)^2 + (2-6)^2)

= √65.

c.  The equation of the circle is:

Using the standard form

(x - h)^2 + (y - k)^2 = r^2  where  (h, k) is the center and r = the radius:

it is (x - (-3)^2 + (y - 2) = 65

= (x + 3)^2 + (y - 2)^2 = 65.

Answer:

a. (-3,2)

b. sqrt(65)

c. (x + 3)² + (y - 2)² = 65

Step-by-step explanation:

Centre:

midpoint of the diameter

(h,k) = (-10+4)/2, (-2+6)/2

(h,k) = (-3,2)

Length of the diameter:

sqrt[(-2-6)² + (-10-4)²]

sqrt(260)

2sqrt(65)

Radius: ½ × diameter

Radius = sqrt(65)

Equation:

(x - h)² + (y - k)² = r²

(x - -3)² + (y - 2)² = (sqrt(65))²

(x + 3)² + (y - 2)² = 65

Answer:

Minimum : 1

Q1 : 8

median or Q2 : 13

Q3 : 20

Maximum : 23

Step-by-step explanation:

Q1 = lower quartile

Q2 = median

Q3 = upper quartile

1 5 8 10 11 12 14 17 19 20 22 23

median or Q2 = 12 + 14 = 26 divided 2 = 13

median = 13

Q1 = 8

Q3 = 20

minimum ( least number) = 1

Maximum ( Greater number ) = 23

Final answer:

The answer explains the statistical measures of minimum, quartiles, and maximum for a given set of numbers in Mathematics at a High School level.

Explanation:

The given numbers are:

Minimum: 1

Q1: 8

Q2: 17

Q3: 20

Maximum: 23

This data represents statistical measures such as minimum, quartiles, and maximum which are essential in data analysis and interpretation in Mathematics at a High School level.

Answer:

Explanation:

To estimate the value, you can work with friendly numbers: numbers closed to the given numbers and with which you can perform easy mental calculations.

For example 4.55 may be rouned to 5, 4.85 may be rounded to 5, and 3.25 may be rounded to 3. That yields 5 + 5 + 3 = 13

Then, it seems you have about 13 liters. Is the final number equal or greater than 12 for sure?

To round 4.55 to 5 you increased the amount in 0.45, to round 4.85 to 5 you increased the amount by 0.15, and to round 3.25 to 3 you decreased the amount in 0.25.

What was the net change in your values: 0.45 + 0.15 - 0.25 = 0.60 - 0.25 = 0.35. Those are easy calculations that you can perform in your mind.

That means that you increased your total in less than 1 liter. Meaning that the final total is overestimated by 0.35, and that if you used the real amounts to make the calculations, the total will be still more than 12.

To convert inches to centimeters, we can multiply the length in inches by 2.54, since 1 inch is equivalent to 2.54 centimeters.

So, to find the length of the ribbon in centimeters, we can multiply 28.75 inches by 2.54 centimeters/inch:

= 28.75 inches x 2.54 centimeters/inch

= 73.025 centimeters

Answer:

4

Step-by-step explanation:

do the math plug it in

4 + 6 = 10,

10 x 2 = 20

20/5 = 4

The value of the smaller number is 4.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by translating the given information into equations.

We can use variables to represent the two numbers, and use the given information to write equations in terms of those variables.

Let x be the smaller number.

Then the larger number is 6 more than x, which we can write as (x + 6).

Twice the larger number is 5 times the smaller, which we can write as:

2(x + 6) = 5x

Now we can solve for x:

2x + 12 = 5x

Subtracting 2x from both sides, we get:

12 = 3x

Dividing both sides by 3, we get:

x = 4

Therefore,

The smaller number is 4.

cosin=cah adjacent over hypotenuse

"The correct ratio representing the cosine of ∠L in ΔKLM is [tex]\(\frac{7}{25}\).[/tex]

In right-angled triangle ΔKLM, where ∠M is 90°, the cosine of ∠L is defined as the ratio of the adjacent side to the hypotenuse.

The adjacent side to ∠L is KM, and the hypotenuse is LK.

 Given that LK = 25 and KM = 7, the cosine of ∠L is calculated as follows:

[tex]\[ \cos(\angle L) = \frac{\text{Adjacent side (KM)}}{\text{Hypotenuse (LK)}} = \frac{7}{25} \][/tex]

This ratio [tex]\(\frac{7}{25}\)[/tex] represents the cosine of ∠L in ΔKLM."

Step-by-step explanation:

Since we have given that

There are three person : Joe, Keitaro, Luis.

And two names will be selected for he game .

Possible events will be

But we want to find the complement of the event in which Joe plays in hte first match,

As we know that complement of any events means eliminate that event from the universal set.

Event of getting Joe plays in the first match is given by

So, complement of this event that Joe plays in the first match is given by

The possible events are:

{JK, JL, KL}

The events where J does not play (the first game) are: {KL}

Answer: A = {KL}

The complement of the event in which Joe plays in the first match is {KL} and the subset of the sample space is {JK, JL, KL}

Complementary events are two events that exist such that one event will occur if and only if the other does not take place.

Given that, Joe, Keitaro, and Luis play tennis. To decide who will play against each other in the first match, they put their names in a hat and choose two names without looking.

There are three persons: Joe, Keitaro, Luis.

There are two names to be selected for the game.

Possible events will be = {JK, JL, KL}

But we want to find the complement of the event in which Joe plays in the first match,

As we know that complement of any events means to eliminate that event from the universal set.

Event of getting Joe plays in the first match is given by = {JK, JL}

So, the complement of this event that Joe plays in the first match is given by = {KL}

Hence, the complement of the event in which Joe plays in the first match is {KL} and the subset of the sample space is {JK, JL, KL}
