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

Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3

Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answers
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.

A) 1d + 12 = 14-20
B) 4(20+5) = 10r
C) -2(5 + x) - 1 = 3(x + 3)
Answers
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

aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold
Answers
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.
The radius of a regular hexagon is 8 cm.
Find the apothem, perimeter and area
of the regular hexagon.
Answers
the measure of the side = of the measure of radius because the regular hexagon have 6 sides = at each others
meaning the measure the perimeter is = 6 times the radius
and the radius = 8cm
so perimeter = 6× 8 cm
perimeter = 48cm
since the apothem is the segment perpendicular to a side thought the center and those segment are not promotional we have the notation as
r square root of 3 divided by 2
r = radius = 8 cm
by apply the formula
8square root 3 divided by 2
so the area will be
since the perimeter is 48cm
and the apothem is 8 square root of 3 divided 2
so the area will be 48 times 8 square root of 3 divided by 2 = 384 square of 3 divided by 2 .
hope that helps.

Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answers
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.

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)

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.
Answers
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
