Answer:
A a. 25 minutes
Step-by-step explanation:
Let x = time in minutes.
Aquarium I contains y water at time x.
y = 4.6 + 1.2x
Aquarium II contains y water at time x,
y = 54.6 - 0.8x
We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.
4.6 + 1.2x = 54.6 - 0.8x
Subtract 4.6 from both sides.
Add 0.8x to both sides.
2x = 50
Divide both sides by 2.
x = 25
Lyla is planning on riding his bike no more than 65 miles during the week. She has already ridden 17 miles. Write and solve an inequality to find how many more miles she can ride. Then interpret the solution.
Answer:
17 + m ≤ 65
Step-by-step explanation:
Maximum distance = 65 miles
Number of miles already ridden = 17
Expression to represent how many more miles, 'm' she can ride ;
Number of miles already ridden + m ≤ maximum distance
17 + m ≤ 65
m ≤ 65 - 17
m ≤ 48
The amount of additional miles Lyla can ride is at most 48 miles

Answer:
Step-by-step explanation:
The end points of PG are given. Find the length of segment PQ using the Pythagorean therom p(-4.3) and q(0,5)
Answer:
4.5 cm
Step-by-step explanation:
Given that the end points of PG are given. Find the length of segment PQ using the Pythagorean theorom p(-4.3) and q(0,5)
Solution
Using the formula;
Length PQ = sqrt ( (X - x)^2 + ( Y - y)^2 )
Length PQ = sqrt( ( 0 + 4 )^2 + ( 5 - 3 )^2)
Length pq = sqrt ( 4^2 + 2^2)
Length PQ = sqrt ( 16 + 4 )
Length PQ = sqrt ( 20 )
Length PQ = 4.47 cm
Therefore , the length PQ is 4.5 cm approximately.

Answer:
the answer is b
Step-by-step explanation:
hope I'm right
Answer:
D. –x^4 + 6x^3 + 7x^2 – 4x – 4
Step-by-step explanation:
When writing in standard form you have to put the monomials from greatest to least according to their exponent.
[tex]-x^4+6x^3+7x^2-4x-4[/tex]
The first number is [tex]-x^4[/tex] because 4 is the greatest exponent we see, then comes [tex]+6x^3[/tex] which is next because it has the second greatest exponent. And so on and so on.

Step-by-step explanation:
a college loan of 15000 has a 3% annual simple interest rate what is the interest the student will pay after 5 years
Answer:
Interest = $ 90000
Step-by-step explanation:
Given, Principal= $15000
Rate = 3%
Time = 5 years
Interest = P × R × T/100
Therefore, Interest = 15000 × 3 × 5/100
(dividing 100 by 5 to get 20)
= 15000 × 3 × 20
= 90000

A) 1d + 12 = 14-20
B) 4(20+5) = 10r
C) -2(5 + x) - 1 = 3(x + 3)
Answer:
A) -18 B) r=10 C) x=-4
Step-by-step explanation:
A) 1d + 12 = 14-20
Step 1: Simplify both sides of the equation.
1d+12=14−20
d+12=14+−20
d+12=(14+−20)(Combine Like Terms)
d+12=−6
d+12=−6
Step 2: Subtract 12 from both sides.
d+12−12=−6−12
d=−18
Answer:
d=−18
B) 4(20+5) = 10r
Step 1: Simplify both sides of the equation.
100=10r
Step 2: Flip the equation.
10r=100
Step 3: Divide both sides by 10.
r=10
C) -2(5 + x) - 1 = 3(x + 3)
Step 1: Simplify both sides of the equation.
−2(5+x)−1=3(x+3)
(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)
−10+−2x+−1=3x+9
(−2x)+(−10+−1)=3x+9(Combine Like Terms)
−2x+−11=3x+9
−2x−11=3x+9
Step 2: Subtract 3x from both sides.
−2x−11−3x=3x+9−3x
−5x−11=9
Step 3: Add 11 to both sides.
−5x−11+11=9+11
−5x=20
Step 4: Divide both sides by -5.
x=−4

3*24=8x (we don't need to multiply 3 with 24 bc we will divide both sides by 8 so it will be easier to find the final value)
x=9
Answer:
x = 9
Step-by-step explanation:
8: 24
Multiply 3
8 x 3 = 24

aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold
Answer:
132.
Step-by-step explanation:
If 12% are sold then 100-12 = 88% are unsold.
12% = 18 oranges
1% = 18/12 = 1.5 oranges,
88% = 1.5 * 88 = 132.
