Answer:
[tex]\frac{p}{u} =k[/tex]
Step-by-step explanation:
A direct proportion means the ratio of p:u is a constant numberThis constant number is denoted by kan example of this is, say for every 1 chicken you buy there are 2 legs which is ratio 1:2 which is [tex]\frac{1}{2}[/tex] so if you add more chickens, you add more legs, 2 chickens means 4 legs, 8 chickens means 16 legs, which is [tex]\frac{1}{2}= \frac{2}{4} =\frac{8}{16} =0.5[/tex] so the constant number is 0.5, so this a direct proportionThe two values grow at the same rateThere is a fee to rent a moving truck from lucky trucks plus $20 per hour Emily route rented a truck for seven hours and pay $200 what is the fee
Answer:
her fee is $140 and she gets back $60
Step-by-step explanation:
step 1: multiply $20 by 7, which gives you 140
step too if you need how much money she gets back take 140 from 200 and you get $60
What is the sum of the roots of the quadratic $4x^2 - 4x - 4$?
9514 1404 393
Answer:
1
Step-by-step explanation:
The sum of roots of quadratic ax^2 +bx +c = 0 is -b/a. Here, that means the sum of roots is ...
-(-4)/4 = 1
The sum of the roots is 1.
Answer:
1/2
Step-by-step explanation:
By Vieta's formulas, the sum of the roots of $ax^2 + bx + c$ is given by $\dfrac{-b}{a}$. For this quadratic, that value is
\[ \frac{-b}{a} = \frac{-(-4)}{4} = 1.\]
Since the sum of the roots is $1$, the average of the roots is $\boxed{\dfrac 1 2}$.
Alternately, we could factor $4$ out of every term of this quadratic, giving $4(x^2 - x - 1)$. Since $4 \cdot 0 = 0$, any number that is a root of $x^2 - x - 1$ will also be a root of $4(x^2 - x - 1)$. Thus, the problem can change to finding the sum of the roots of $x^2 - x - 1$.
Since the coefficient of the linear term is $-1$ and this is the opposite of the sum of the roots, we find that the sum of the roots is equal to $1$, and the average is $\boxed{\dfrac 1 2}$.

Answer:
t≤ 9
Step-by-step explanation:
3.5+4t≤ 39.5
subtract 3.5 from each side
4t≤ 36
divide each side by 4
t≤ 9
Answer:
t ≤ 9
Step-by-step explanation:
3.5 + 4t ≤ 39.5
3.5 + 4t - 3.5 ≤ 39.5 - 3.5
4t ≤ 36
4t ÷ 4 ≤ 36 ÷ 4
t ≤ 9

Answer: I think its D
Step-by-step explanation:
The angle measures of a triangle are shown:
Angle A: (5x – 5) degrees
Angle B: (3x + 3) degrees
Angle C: (5x) degrees
The sum of the measures of the three angles is equal to 180°. What is the measure of Angle B?
Answer:
∠ B = 45°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
5x - 5 + 3x + 3 + 5x = 180, simplify
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Thus
∠ B = 3x + 3 = 3(14) + 3 = 42 + 3 = 45°
What is the slope of the line
Answer:
1.5
Step-by-step explanation:
pick two points on the graph I chose (3,0) and (1,-3) do y2 minus y1 over x2 minus x1. so 0 minus -3. and 3 minus 1 equals 3 over two or 3 divided by two and once it's divided you get 1.5

Layala and Zahra have 2700 marbles in the ratio of 2:7. How many marbles Zahra must have gave away so that they both would have the same number of marbles?
Answer:
1500
Step-by-step explanation:
Given that :
Total number of marbles held by Layala and Zahra = 2700
Ratio = 2 : 7
Layala's share of marbles : (2 / (2+7)) * 2700
= 2/9 * 2700
= 600
Zahra's share of marble : (7 / (2+ 7)) * 2700
= 7 / 9 * 2700
= 2100
Hence, Zahra must have given away (2100 - x) = 600
2100 - 600
= 1500 marbles, so that both Zahra and Layala have the same number of marbles

A comer store sells two kinds of baked goods: cakes and pies. A cake costs $8 and a pie costs $11. In one
day, the store sold 11 baked goods for a total of $112. How many cakes did they sell?
a. 3 cakes
c. 2 cakes
b 11 cakes
d. 8 cakes
Answer:
8 number of cakes were sold.
Step-by-step explanation:
Out of 12 baked goods sold , let the number of cakes sold be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8 Therefore, 8 cakes were sold [Ans]
Answer:
3 cakes
Step-by-step explanation:
3x8=24
112-24=88
88/11=8
3cakes +8 pies= 11 baked goods

Two pizza parlors in town are offering special rates to attract group reservations. Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered. Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered. Compare the costs of holding an event at the two pizza parlors.
Write and solve a system of linear equations to model the cost of an event at each pizza parlor.
a. Write an equation to represent the cost for a party at Stella’s Pizza.
b. Write an equation to represent the cost for a party at Napoli’s Pizza.
c. What is the solution to the system of equations? (label your answers)
Answer:
x = 2 pizzas
Step-by-step explanation:
Let
x = number of pizza ordered
Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered.
cost for a party at Stella’s Pizza = 16 + 8x
Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered.
cost for a party at Napoli’s Pizza = 24 + 6x
Equate the cost for a party at Stella’s Pizza and cost for a party at Napoli’s Pizza
16 + 8x = 24 + 6x
8x - 6x = 24 - 16
2x = 8
x = 8/4
= 2
x = 2

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
Answer:
4 is the maximum number of ride tickets she can buy
Step-by-step explanation:
Here, r represents the number of ride tickets and f represents number of food tickets.
The system of inequalities is given as:
r+f\geq 16 ....[1]
4r+2f\leq 40 .....[2]
To solve Mathematically:
Multiply equation [1] by -2 we have;
-2r-2f \leq -32 .....[3]
Add equation [2] and [3] we have;
2r \leq 8
Divide both sides by 2 we have;
r \leq 4
Since r must be less than or equal to 4.
You can also see the graph of the given system of inequalities as shown below.
The intersection point is, (4, 12)
Therefore, the maximum number of ride tickets she can buy is, 4

A. 4
