Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15

what is the lcm of 6 and 8
Answer:
The LCM, or least common multiple, of 6 and 8 is 24.
Answer: 2
Step-by-step explanation:
First you find the multiples of 6 and 8 then you do this.
2x3
2x2x2x2x2x4

On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?
Answer:
Number of apples ate = 5
Step-by-step explanation:
Fact:
One of them always tells the truth, while the other always lies.
To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.
Ana: "Banana ate ten apples yesterday, and he is telling the truth."
If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).
This is not possible as one of them must be lying. The only option left is that Ana is lying.
Since Ana is lying, it means banana is telling the truth.
Banana: "No, I ate five apples yesterday, and Ana is lying."
Number of apples ate = 5

3(1 - 2a) = -3a - 18
Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7

Lily wants to ride her bicycle 43 miles this week. She has already ridden 16 miles. If she rides for 6 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
43-16=miles left to go. divide that by the 6 days left.
43-16= 27 miles.
27÷6= 4.5 miles per day
Answer:
4 1/2 miles
Step-by-step explanation:
43 - 16 = 27 miles remaining
27/6 = 4 3/6 or 4 1/2
What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.
Answer:
slope = -10/7Step-by-step explanation:
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7

A consumer charges a 2530.16 purchase on the credit card the card has a daily interest rate of .042% if the consumer piece of the balance at the end of 30 days how much more in interest will they pay for the purchase? A point $.32 be $3.19 C $31.88 D $318.78
Answer:
$31.88
Step-by-step explanation:
Given
Consumer charges = 2530.16cents
Consumer charges in dollars = $25.3016
Interest rate per day = 0.042%
Interest gotten per day = 0.042×25.3016
Interest per day = $1.06266
Interest in 30 days = ,30×1.06266
Interest in 30 days = $31.88

Step-by-step explanation:
A population of bacteria grows according to the function p(t) = po · 1.42, where t is measured in hours. If
the initial population size was 1,000 cells, approximately hoy long will the it take the population to exceed 10,000
cells? Round your answer to the nearest tenth.
Answer:
The time duration for the population to exceed 10,000 is approximately 6.6 hours
Step-by-step explanation:
The given equation for the population of a bacteria is presented as follows;
[tex]p(t) = P_0 \cdot 1.42^t[/tex]
Where;
t = The time duration in hours
The initial population of the cells = 1,000
Therefore, at t = 0, P(0) = 1,000 = P₀ × 1.42^0
∴ P(0) = 1,000 = P₀ × 1 = P₀
P₀ = 1,000
When the population is 10,000, we have;
P(t) = 10,000 = 1,000 × 1.42^t
∴ 1.42^t = 10,000/1,000 = 10
㏒(1.42^t) = ㏒(10) = 1
∴ t × ㏒(1.42) = 1
t = 1/㏒(1.42) = 6.56649071898
∴ The time duration for the population to exceed 10,000, t ≈ 6.6 hours.

You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than $\frac{2}{3}$ of the elevation of the entrance. What is the elevation of the entrance?
Answer:
the elevation of the entrance is -21
Step-by-step explanation:
The computation of the elevation of the entrance is shown below;
-15 = -1 + 2 ÷ 3e
e = -21
Hence, the elevation of the entrance is -21
We simply applied the above equation so that we can determine the elevation of the entrance

A student worked out the following problem: Solve: 8x + 10 – 6x + 4 = 24 Step 1: 2x + 14 = 24 Step 2: 2x = 38 Step 3: x = 19
A) There is an error in step 1
B) There is an error in step 2
C) There is an error in step 3
D) There is no error
Answer
b
Step-by-step explanation:
Answer:
B) There is an error in step 2.
Step-by-step explanation:
When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).
After combing your like terms, you now have the equation 2x+14=24.
You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10
This is where the student made the mistake. Instead of subtracting 14, they added 14.
The final step would be to divide by 2 on both sides.
At the end of the problem, you are left with x=5.

What is the length of a rectangle with an area of (4x^2-10x-6) and a width of (x-5)
Help lleaseee
The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.
Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17
