Answer:
5:00
Step-by-step explanation:
1 hour 21 minutes = 1,35 hours
30 minutes = 0,5 hours
1,35-0,5=0,85 hours he needs to get to school
7-0,85=6,15

In general, you solve these the same way you would an equation. The difference comes when you use an operation that changes ordering. Multiplying or dividing by a negative number does that, for instance.
Consider ...
2 > 1.
Multiply both sides by -1, and it is true only if you reverse the comparison:
-2 < -1
(There are other operations that change ordering, but this is the one you will likely run across most often.)

In ΔKLM, the measure of ∠M=90°, LK = 25, KM = 7, and ML = 24. What ratio represents the cosine of ∠L?
Answer:
24/25
Step-by-step explanation:
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."
louis and valentina have 60 toys to build louis builds 1/2of the toys while valentina builds 2/5 how many toys are left
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

What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
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
Therefore,

What is an expression?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.

The following numerically ordered sequence of numbers has a mean of 17 and a median of 18.
7, a, 12, 15, 17, b, 20, 22, 24, 25
Given this information, the values of a and b must be:
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

Given :
Glen received a $2,250 loan from the bank. After six months, he paid back $2,295 and closed the loan.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.

A diameter of a circle has endpoints P(-10,-2) and Q(4,6).
a. Find the center of the circle.
b. Find the radius. If your answer is not an integer, express it in radical form.
c. Write an equation for the circle.
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

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}
What is a complement of an event?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.

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}

For 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.
What is the rate of change?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
