Justine lives in an apartment while attending college. Her monthly rent last year was $680, but this year she has to pay $800 per month. By what percent did her monthly rent increase from last year to this year?
Answer:
6,528,000
Step-by-step explanation:
Multiply 800 by 12. Then multiply the number by 680. And there u go.
6,528,000
The percent did monthly rent increase from last year to this year is 17.6%
Last year Justine paid $680 in rent while this year she paid $800 in rent
The increase in rent = $800 - $680 = $120
The percentage increase in rent = ($120/$680) * 100% = 17.6%
The percent did monthly rent increase from last year to this year is 17.6%

Step-by-step explanation:
Given
5| x - 7 | + 4 = 4 ( subtract 4 from both sides )
5 | x - 7 | = 0 ( divide both sides by 5 )
| x - 7 | = 0, thus
x - 7 = 0 ( add 7 to both sides )
x = 7 ← is the only solution → C

A man travels at 42 degrees northwest, and ends up 8.5 miles west of his starting point. How far did he travel?
Answer:
The man traveled 12.70 miles.
Step-by-step explanation:
We can find the distance traveled by the man knowing:
[tex]d_{W}[/tex]: the distance at the west = 8.5 miles
[tex]\theta_{NW}[/tex]: the northwest angle = 42°
Then by using the following trigonometric identity we have:
[tex] sin(\theta) = \frac{d_{W}}{d_{NW}} [/tex]
[tex] d_{NW} = \frac{d_{W}}{sin(\theta)} = \frac{8.5 miles}{sin(42)} = 12.70 miles [/tex]
Therefore, the man traveled 12.70 miles.

Which is greater, 4 4/10 or 32/10? Explain how u know.
Answer:
4 4/10
Step-by-step explanation:
Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.
Fractions may be equal or unequal.
[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
The fractions are given as:
[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]
[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]
Express the fractions as improper fractions
[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]
Both fractions have the same denominator.
So, the fraction with a greater numerator is greater.
By comparison: 44 is greater than 32
i.e. 44 > 32
Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

Answer:
(x+3)(x+9)=x²+12x+27
2x²+24x+54=374
2x²+24x-320=0
x²+12x-160=0
x=-20 x=8
2cm,(-20+3)cm,(-20+9)cm
L=2cm W=-17cm H=-11
Step-by-step explanation:
Expand (x+3) and (x+9) -----> x^2+12x+27
Multiply the answer by two 2x^2+24x+54
Move 374 to the side by taking away ----->54-374=320
Divide the whole equation by 2 ---> x^2+12x-160

The Width of cuboid is 11cm and Height of cuboid is 17 cm
What is Quadratic Equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax²+ bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a≠ 0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.
Given:
Volume of Cuboid= 374
length= 2cm
width= x+ 3
height= x+ 9
Now, Volume of cuboid= length x width x height
2(x+3)(x+9)=374
2(x² + 12x +27)= 374
x² + 12x +27 = 187
x² + 12x -160=0
Now, factorizing
x² + 20x -8x-160=0
x( x+20) -8(x+ 20)=0
(x+ 20)(x - 8)=0
x= 8 and x= - 20
As. the dimensions cannot be negative.
So, Width= x+3 = 8+3 = 11cm
Height= x+9 = 3+9 = 17 cm

Keith decided to do pushups everyday as part of his exercise routine. He started to do 10 pushups today and he will be adding 3 additional counts for each day that his exercise continues. How many pushups will Keith do if he is exactly on his 3rd week of his exercise routine?
Answer:
55 push ups
Step-by-step explanation:
Given that:
Starting count = 10
Additional count = 3
Starting count + (additional count * number of days)
Exactly on the 3rd week = on the 15th day
10 + (3 * 15)
10 + 45

What lever has resistance between the axis (fulcrum) and the force (effort)? A. first B. second C. third D. fourth Please select the best answer from the choices provided. A B C D
Answer:
B. Second
Step-by-step explanation:
Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.
What is lever?A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever.
here, we have,
The difference between different types of levers are:
1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.
2. The second class levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.
3. The third class levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.
Thus, the correct answer is Option 1.

Answer:
area = x(3x +10)
Step-by-step explanation:
The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.
horizontal unmarked = (2x+15) -x = x +15
vertical unmarked = (2x -5) -(x -5) = x
The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.
The whole area is ...
x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)

sides to stabilize the structure. I would like to know how many
cubes I will need to build a 5-block high tower and a 10-block
high tower. Generalize, if you can, on how many blocks I will
need for any size tower?
Answer:
is there an equation for this or simple math?
