A rectangle has a length of (5x+2) and a width of (3x-7). Find the perimeter of the rectangle.
Answer:
Perimeter = 2(5x-2)+2(3x-7)
Step-by-step explanation:
The perimeter (P) of any rectangle can be represented in terms of length (L) and width (W) with the equation P=2L+2W.
You multiply the length and width of the rectangle by two, since it's only giving one expression for the length and width.
Hope this helps!
can any one figure this out plz
Answer:
(a)(b)=0.45
a/b=0.8
Step-by-step explanation:
a=0.6
b=0.75
(a)(b)=(0.6)(0.75)=0.45
a/b=0.6/0.75=0.8
Answer:
a*b = 0.5
a/b = 0.888...
Step-by-step explanation:
0.6666... = 2/3
a*b = 2/3 * 3/4 = 1/2 = 0.5
a/b = (2/3) / (3/4) = 8/9 = 0.888...

Step-by-step explanation:
3/(3+x-6)=5/(5+x)
cross multiply
3(5+x)=5(3+x-6)
15+3x=15+5x-30
15+3x=5x-15
15+15=5x-3x
30=2x
x=15
That means KQ=15 and PK=15-6=9. Now we have to find PQ, which is the same as JM. We’ll call that length b.
5/15=6/b
cross multiply
5b=90
b=18
15+9+18=42
A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?
Answer: The team needs to win 15 more games to get 90% winning percentage.
Step-by-step explanation:
80%=4/5 divide 15 by 5 and you get 3, which is 1/5 of 15, so you must multiply it by 4 to get 80% of 15 which is 3*4=12
If you want 90%(or 9/10) of 30, you do the same thing, and you get 27.
27-12=15.
The team needs to win 15 more games to get 90% winning percentage
A line passes through the points (0, 2) and (1, 8). What is its equation in slope-intercept form?
Answer:
y=6x+2
Step-by-step explanation:
y=mx+b
-the y and x are variables and your going to want to leave them that way.
-m is the slope
-b is the y-intercept
after plotting your points and drwaing a line through them you get your final equation

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x. What is the constant of proportionality?
A:135
B:225
C:315
D:90
Answer:
The constant of proportionality is 225
Step-by-step explanation:
Given
[tex]y = 225x[/tex]
Required
Determine the constant of proportionality (k)
A direct proportion is represented as:
[tex]y = kx[/tex]
Where k is the constant of proportionality
By comparing:
[tex]y = kx[/tex] to [tex]y = 225x[/tex]
Hence:
[tex]k = 225[/tex]
Calculate the volume. Use a ~ 3.14 and round to the nearest whole number

es perpendicular 3x+y-9=0 y pasa por el origen (0, 0).
Answer:
[tex]y = \frac{1}{3} x[/tex]
Step-by-step explanation:
Una recta que es perpendicular a la pendiente de una ecuación es la recíproco negativo. de l
a ecuación original.
Primero, este problema está en forma estándar, así que conviértalo a la forma de intersección de pendiente
[tex]3x + y - 9 = 0[/tex]
[tex]3x + y = 9[/tex]
[tex]y = 9 - 3x[/tex]
[tex]y = - 3x + 9[/tex]
Ahora encuentre el recíproco negativo de la pendiente que es -3x
[tex] \frac{ - 3}{1} [/tex]
[tex] - ( - \frac{3}{1} [/tex]
[tex] \frac{1}{3} [/tex]
La pendiente es 1/3, así que sepa que introduzca 0 para nuestro valor X para encontrar nuestro valor y
[tex]y = \frac{1}{3} x[/tex]
[tex]y = \frac{1}{3} (0)[/tex]
y=0

Some people believe there are too many taxes and that tax rates
are too high. They refuse to file tax returns or pay taxes because
they disagree with how the government spends the money. Do you
agree with these arguments? Why or why not?
Answer:
Step-by-step explanation:
(This is technically a personal opinion question) In MY opinion all government run things from libraries to schools to the military come from taxes. If you don't agree with how the government spends the money that you pay in taxes yet enjoy/use government facilities then you have no room to complain and not pay your taxes.

. In a group of 37 people waiting in line at the local java house, 18 wanted to order a cappuccino, 20 wanted to
order a latte, and 2 wanted neither of these drinks. How many wanted to order both a cappuccino and a latte?
Answer:
36
Step-by-step explanation:
Its 36 because normally someone would do 18+20=38 but you have to remeber in the problem it says 37! so 2 people didn't want anything, minus that and you get 36.

What is the distance from X to Y?
A. 15 units
B. 3 units
C. 225 units
D. 21 units
Answer:
15, A
Step-by-step explanation:
(0,6) (9,-6)
distance formula =
[tex]d= \sqrt{(x_2-x_1)²+(y_2-y_1)² }[/tex]
lets put our numbers
[tex]d= \sqrt{(0 - 9)²+(6+ 6)² }[/tex]
so answer will be = 15, A

Answer:
x = 70
Step-by-step explanation:
As the problem states, ∠ABD and ∠DBC are supplementary angles. This means they have a sum of 180°. Since we know this, we can set up an equation to solve for x.
x + 110 = 180
x = 70
