Step-by-step explanation:
y = 5 4x+6y= 62 Solve forx
Answer:
x = 8
Step-by-step explanation:
4(8) + 6(5) = 62
32 + 30 = 62
62 = 62
Answer:
x = 8
Step-by-step explanation:
y = 5 and 4x + 6y = 62
4x + 30 = 62
Subtract 30 from each side:
4x + 30 - 30 = 62 - 30
4x = 32
Divide each side by 4:
4x ÷ 4 = 32 ÷ 4
x = 8

=log(100x4) - log4
=log100 + log4 -log4
= log100
Step-by-step explanation:
log400 = log 100x4 but log ab = log a + log b
wally uses his own recipe for mixing glittered paint. he recently mixed 3 1/3 cup of glitter to make 2 1/2 gallon of paint. how much glitter does wally use in each gallon of paint.
Answer:
4/3s per gallon
Step-by-step explanation:
3 and 1/3= 10/3
So you know that in the whole 2 and 1/2 gallons of paint, there are 10/3s cups of glitter.
So that means you have to split the 10/3 cups into the 2 and 1/2 gallons.
Thus, in one gallon there is 4/3s.
One gallon 4/3s+ One gallon 4/3s+One half of a gallon 2/3s=10/3s
4/3+4/3+2/3=10/3
So each gallon has 4/3s cups of paint

Ms. Clandestine is planning to take her study group on a field trip to an amusement park. The regular cost is $25 per person. There is a party special that costs $15 per person with an additional $150 fee for a private room where students can eat lunch. Ms. Clandestine is trying to decide if she should use the regular price or the party special.
Question 1:Write an equation to show the total cost of the regular price with x people.
Group of answer choices
y=5x + 2
y=2x + 5
y=25x
None of the above
Question 2:Write an equation to show the total cost of the party special with x people.
Group of answer choices
y=15x + 25
y=15x + 150
y=150x + 15
None of the above
Question 3: What is the solution to this system?
Group of answer choices
(-375, 15)
(-15, 375)
(375,15)
(15,375)
Question 4: What does the solution mean in relation to THIS PROBLEM?
Question 1:
Multiply the regular price by the number of people (x)
Y = 25x
Question 2:
Multiply the special rate by number of people(x) and add the cost of the room:
Y = 15x + 150
Question 3:
Replace x with a positive value and solve for y, which will be larger than the x value
Answer (15,375)
Question 4:
This means for 15 people the total cost for the special rate would be $375
Solve the given equation.

z
Answer:
[tex]z=-317[/tex]
Step-by-step explanation:
1) Simplify 45 × 28 to 1260.
[tex]1260=19*83+z[/tex]
2) Simplify 19 × 83 to 1577.
[tex]1260=1577+z[/tex]
3) Subtract 1577 from both sides.
[tex]1260-1577=z[/tex]
4) Simplify 1260 - 1577 to −317.
[tex]-317=z[/tex]
5) Switch sides.
[tex]z=-317[/tex]
Therefor, the answer is z = -317.
In a class of 23 students, 18 are female and 7 have an A in the class. There are
5 students who are female and have an A in the class. What is the probability
that a student chosen randomly from the class is a male?
Answer:
5/23
Step-by-step explanation:
23 students, 18 females so 5 males
In this case, the probability of a male student being chosen at random from the class is 5/23.
Definition of classical probability:The probability of an event is the ratio of the number of cases favorable to it to the total number of cases possible when nothing leads us to expect any of these cases to occur more than any other, making them equally possible for us.
i.e. probability of an event = number of the possible outcome of an event/number of total outcomes in the sample space
What is an event?An event is a set of outcomes of an experiment to which a probability is assigned in probability theory.
What is a sample space?A sample space is a set of possible outcomes from a random experiment.
How to solve this problem?Here, the random experiment, in this case, is "a student chosen at random from the class". There are 23 students in the class. So, the number of total outcomes in the sample space is 23. Let us consider the event as “the randomly chosen student is a male”.
Since there are 18 female students in the class, so the number of male students is (23-18)=5.
i.e. the number of the possible outcome of this event is 5.
Therefore the classical definition of probability, we can conclude that
Required Probability = 5/23
Hence the probability that a student chosen randomly from the class is a male is 5/23.

a point is chosen at random in the circle. What percent of the time will the point be in the square? Round to the nearest tenth of a percent.
Answer:
P = 0.637
Step-by-step explanation:
By a small online search, i've found that the image is a circle of radius R = 1in, and a square inside of the circle, such that the distance between the center of the square and the one vertex of the square is one inch.
To solve this problem, we need to find the area of each figure.
The area of a circle of radius R is:
A = 3.14*R^2
Then the area of our circle is:
A = 3.14*(1in)^2 = 3.14 in^2
Now for the square.
If the distance between the center and one vertex is 1 inch, then the distance between two opposite vertex is twice that: 2 inches.
Now we can think of a triangle rectangle, where both catheti are equal to L, the side length of the square, and the hypotenuse is 2 inches.
Using the Pythagoreans theorem, we get:
L^2 + L^2 = (2in)^2
2*L^2 = (2in)^2
L^2 = (2in)^2/2 = 2 in^2
L = √(2 in^2) = √2 in
And the area of a square of side length L, the area is:
A = L^2
Then the area of our square is:
A = (√2 in) = 2 in^2
Then:
Area of the circle = 3.14 in^2
Area of the square = 2 in^2
The area of the circle represents the 100% (if a point is chosen at random in the circle, the probability that the point will be inside the circle is P = 1)
The probability that the point will be inside the square is equal to the quotient between the area of the square and the area of the circle, this is:
P = (2 in^2)/(3.14 in^2) = 0.637

in a straight diagonal line, 0.6 miles north and 8.5 miles west every minute. A lion leaves the west edge of the
preserve 51 miles north of the station at the same time the ranger leaves from the southern border, also in a
straight diagonal line. Every minute the lion moves 0.1 miles north and 0.3 miles east.

EXPRESS THE AREA OF THE ENTIRE RECTANGLE. YOUR ANSWER SHOULD BE A POLYNOMIAL IN STANDARD FORM
Answer:
(x+7) times (x+3)
Step-by-step explanation:
Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.
The area of the rectangle will be (x² + 10x + 21) unit².
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
Now,
Since, The Length of the rectangle = x + 7
And, The width of the rectangle = x + 3
We know that;
The area of rectangle = Length × Width
= (x + 7) × (x + 3)
= x² + 3x + 7x + 21
= x² + 10x + 21
Thus, The area of rectangle = (x² + 10x + 21) unit²
