Janice works part-time in a pizza restaurant. She makes a monthly salary of $240. She spends 3/5 of her salary on gas for her car. How much does Janice have left at the end of the month for her other expenses
Answer: 144
Step by step: In order to solve this easily, you should convert 3/5 into a decimal. In order to do that, you have to divide the numerator by the denominator. 3 divided by 5 = 0.6. Then you multiply 240 by 0.6 to get your answer, 144.

3/4 and 1/6 find the least common denominator
Answer: 12 is the least common denominator
Step-by-step explanation:
The least common denominator is the greatest multiple that the two denominators share.
So find the multiples of 4 and 6.
LCM of 4. is 4 ,8 ,12,16,20,24, 28,32,
LCM of 6 is 6,12,18,24,30,36, 42,48
The first multiple that they share is 12
Solve a = 2x + 6xz for X
Answer:
See Below.
Step-by-step explanation:
We are given the equation:
[tex]a=2x+6xz[/tex]
And we want to solve for x.
On the right-hand side, we can factor:
[tex]a=x(2+6z)[/tex]
And divide both sides by the factored expression. Hence:
[tex]\displaystyle x=\frac{a}{6z + 2}[/tex]
And we're done!
Answer:
x=a/2(1+3z)
Step-by-step explanation:
Find the sum 32 +33 +34 + 35 + ... + 112 + 113.
Answer:
5945
Step-by-step explanation:
The sum for an arithmetic series is given by the formula:
[tex]S=(x_1+x_k)\cdot\frac{k}{2}[/tex]
Where x₁ is the initial term, x_k is the last term, and k is the number of elements in the series.
From the sequence, we can see that the first term is 32. The last term is 113.
To determine how many elements we have, subtract 113 and 32:
[tex]113-32=81[/tex]
However, we must add 1 to this number since this doesn't include the first term. Thus:
[tex]81+1=82[/tex]
So, there are 82 terms in total.
Therefore, our sum is:
[tex]S=(32+113)\cdot\frac{82}{2}[/tex]
[tex]S=(145)\cdot 41=5945[/tex]
Answer:
5945
Step-by-step explanation:
an = a1 + ( n - 1) 1
a1 = first term
n = number of terms
an = last term
113 = 32 + ( n - 1 ) 1
113 = 32 + n -1
113 = 31 + n
n = 113 - 31
n = 82.
Sn = n/2(a1 + an)
S82 = 82/2 (32 + 113)
S82 = 41 (145)
S82 = 5945.
The perimeter of a rectangle is 36 feet. If the length is 13, find the width
Answer: 5 feet
Step-by-step explanation: To find the width of the rectangle,
start with the formula for the perimeter, shown below.
Perimeter = 2l + 2w
Since we know the perimeter is 36 and the
length is 13, we have 36 = 2(13) + 2w.
Simplifying on the right, we have 36 = 26 + 2w.
Not subtract 26 from both sides to get 10 = 2w.
Now divide both sides by 2 and 5 = w.
So the with is 5 feet.
A person on the top of a tall building looks through his binoculars at his friend that is 300 ft away from the building on the ground. If the angle of depression from the person on the building is 30°, how far are the two people away from one another? Round your answer to the nearest foot.
Answer:
520 feet
Step-by-step explanation:
The easiest way to visualize this problem is to sketch a quick diagram.
For this problem, you are given an angle and the length of the side of a triangle. If you look at the diagram, you'll see that the length given is the opposite side of the angle given. For this situation, that means you will use the sine function (refer to SOH-CAH-TOA acronym). Then you plug in the given values and solve for x.

Let u = 2i + j, v = i + j, and w = i - j. Find scalars a and b such that u= av + bw.
Answer:
1/2 and 3/2Step-by-step explanation:
Given the expression u= av + bw where u = 2i + j, v = i + j, and w = i - j, to find the scalars a and b, we will first substitute the vectors into the expression given as shown;
u= av + bw
2i + j = a( i + j)+b(i-j)
open the parenthesis
2i + j = ai+aj+bi-bj
collect like terms at the right hand side of the equation
2i + j = ai+bi+aj-bj
2i + j = (a+b)i+(a-b)j
compare the coefficient of complex value i and j on both sides
a+b = 2 ............... 1
a-b = 1................. 2
solve the resulting equation simultaneously using elimination method
Subtract both equation from each other.
(a-a) +(b-(-b))= 2-1
0+2b = 1
b = 1/2
Substitue b = 1/2 into equation 2 to get a
From equation 2, a = 1+b
a = 1 + 1/2
b = 3/2
Hence the scalars a and b are 1/2 and 3/2 respectively
[tex]a=\frac{3}{2},b=\frac{1}{2}[/tex]
A complex number is of the form [tex]\boldsymbol{a+ib}[/tex] where [tex]a,b[/tex] are real numbers.
[tex]u=2i+j[/tex]
[tex]v=i+j[/tex]
[tex]w=i-j[/tex]
[tex]u=av+bw[/tex]
So,
[tex]2i+j=a(i+j)+b(i-j)[/tex]
[tex]2i+j=(a+b)i+(a-b)j[/tex]
Therefore,
[tex]2=a+b\\1=a-b[/tex]
Add these equations.
[tex]3=2a\\\frac{3}{2}=a[/tex]
So,
[tex]1=\frac{3}{2}-b\\\\b=\frac{3}{2}-1\\[/tex]
[tex]=\frac{1}{2}[/tex]

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour.
Answer:
[tex]Rate = 0.2167\ fl\ oz/hour[/tex]
Step-by-step explanation:
Given
[tex]Rate = \frac{91\ fl\ oz}{2.5\ weeks}[/tex]
Required
Express the rate as per hour
[tex]Rate = \frac{91\ fl\ oz}{2.5\ weeks}[/tex]
There are 168 hours in a week;
So, the rate becomes
[tex]Rate = \frac{91\ fl\ oz}{2.5 * 168\ hours}[/tex]
[tex]Rate = \frac{91\ fl\ oz}{420\ hours}[/tex]
[tex]Rate = 0.2167\ fl\ oz/hour[/tex]
Hence;
The equivalent of the given rate is [tex]0.2167\ fl\ oz/hour[/tex]
Area of triangle=42, the width is x+3 and the length is 2x+8, find the value of x
Step-by-step explanation:
Area of triangle = 1/2 × the width × the length
42 = 1/2(x+3)(2x+8)
42 = 1/2×2×(x+3)(x+4)
42 = (x+3)(x+4)
(x+3)(x+4) = 42
x² + 7x + 12 = 42
x² + 7x + 12 - 42 = 0
x² + 7x - 30 = 0
(x-3)(x+10) = 0
x = 3, -10
x can't be -10 because the width and the length should be only + values
x = 3
The value of x found by using the area of triangle concept is 3
What is the Area of a Triangle?
The entire area filled by a triangle's three sides on a two-dimensional plane is referred to as the triangle's area. The fundamental equation for a triangle's area is A = 1/2 b × h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, may be calculated using this formula. It is important to keep in mind that a triangle's base and height are perpendicular to one another.
In the question, It is given that:
Area of triangle = 42.
Width of the triangle = x+3
Length of the triangle = 2x+8;
And, we know that:
Area of triangle = [tex]\frac{1}{2}[/tex]×[tex]lw[/tex]
⇒[tex]42[/tex] = [tex]\frac{1}{2}[/tex]×[tex](x+3)(2x+8)[/tex]
⇒42 = (x+3)(x+4)
⇒(x+3)(x+4) = 42
⇒x² + 7x + 12 = 42
⇒x² + 7x + 12 - 42 = 0
⇒x² + 7x - 30 = 0
⇒(x-3)(x+10) = 0
⇒x = 3, -10
x can't be -10 because the width and the length should be only + values
⇒x = 3
Hence, The value of x is 3.

Suppose the average yearly salary of an individual whose final degree is a master's is $41 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn $115 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answer:N/B The amount is in thousands
The total amount earned by a Bachelor's person be $x:
amount earned by a masters person will be $(2x-38)
Total amount earned by the two individuals will be:
x+(2x-38)=115
solving for x we get:
x+2x-38=115
3x=115+38
3x=153
x=153/3
x=51
also:
2x-38=2*51-38=64
therefore we conclude that master's individual earns average of $ 64,000 while the Bachelor's individual earns $51,000.

2x+2=-59 I need help I don’t know the answer
Answer:
x= -30.5
Step-by-step explanation:
In order to solve equations like this, we need to have all the x terms on one side, and all the other terms on the other side. For this equation so far, the x term (2x) is not alone (there is a +2) so we need to move the +2 to the other side to have x by itself. Whatever you do to one side of equation, you must also do to the other side to keep the equation equal. Therefore we can subtract 2 from both sides which moves the two to the other side while keeping the equation equal. In order to move a term to the other side, we must do the operation opposite to what the term has. E.g. +2 is adding 2, so to move it to the other side, we need to subtract 2.
2x +2 -2 = -59 -2
Which cancels out the 2 on the left side and gives us:
2x = -59-2
2x = -61
Then we just need to remove the 2.
In this case, this 2 is being multiplied to the x, so to move it, we will need to divide both sides by 2.
2x/2 = -61/2
which finally gives us:
x = -30.5
