Answer: (11x6) -8
Step-by-step explanation: Since there are 11 bars in each of 6 boxes, there is 66 bars, since she eats 8 there a 5re8 granola bars left, so the actual expression would be (11x6) - 8.
Hope this helps! :)
I don’t understand 8(3m+5)=2m-4
Answer:
m = -2
Step-by-step explanation:
[tex]8(3m + 5) = 2m - 4\\\\24m + 40 = 2m - 4\\\\22m = -44\\\\m = -2[/tex]
First, distribute and then combine like terms. Then isolate the variable.
Hey! Hope this helps!! Have a great day/ night (wherever you are) : )
Answer:
m= -2
Step-by-step explanation:
Using PEMDAS, (3m+5) is first, so 3(-2)+5 is -1. 8 times -1 is -8. 2(-2) is -4 and -4 is -8.

A cyclist rides her bike at a rate of 10 meters per second. What is this rate in kilometers per hour? How many kilometers will the cyclist travel in 2 hours?
Do not round your
answers.
(i’ll give brainliest)
Answer:
10 meters/sec
1 meter=.001km
10meter=.01km
1hr=3,600 seconds
3,600 sec x .01km = 36 km per hour
36 km/hourx2 hours= 72 km in 2 hours
Find the perimeter??? Anyone?!!!!
Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42
PLEASE HELP QUICK THANK YOU
2. A drink recipe calls for orange juice and pineapple juice. This equation represents the proportional relationship
between the number of cups of orange juice (r) and pineapple juice (p) in the recipe.
3r= 12p
What is the number of cups of orange juice used for 1 cup of pineapple juice?
a. 1/4
b. 3
c. 4
d. 12
Answer:
a. 1/4
Step-by-step explanation:
3r=12p
Divide the left side by 12 to get 1 cup of pineapple juice.
3r=12p
---- = p
12
So now you have
3r=p
BUT you have to divide BOTH sides by 12 so
3r=p
---
12
NOW you have
3/12 r = p
Simplify.
1/4r = p
So 1 cup of pineapple juice is equivalent to a quarter cup of orange juice!
A golfer earned the following scores over several rounds of golf: −3, 2, 0, −1, 2, −4. Jamar says these numbers can all be described as integers, while Sophia says they are whole numbers. Which student is correct? Explain how you know.
Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.

A rectangle is four times as long as it is wide. The perimeter is 40 cm. Find the length of each side.
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16

Imagine that you randomly select a sample of 30 newborn infants and find that their mean weight is 8.1 pounds. The population mean of newborn infants is known to be 7.4 pounds with a standard deviation of 1.1 pounds. Would a sample mean as large as 8.1 be more or less likely if N = 10? Why?
Answer: more likely
Step-by-step explanation:
Given that :
Population Mean = 7.4
Population standard deviation = 1.1
Sample mean with a sample size of 30 = 8.1
A sample mean of 8.1 will be more likely with a sample size (N) of 10 because, the sampling distribution gets wider with decreasing sample size and narrower with larger sample sizes, hence, sample mean seems to conform with the population mean when the sample size are very large according to the central limit theorem. Hence, since a sample size of 30 results in a sample mean of 8.1, reducing the sample size will either give a similar sample mean or a sample mean further away from the population mean.
A mallard duck is 56 to 65 cm long if the duck travel 97.8 miles at top speed in 1.5 hours how far did it travel in 1 hour

97.8 divided by 1.5 then multiply that by 1hr
Suppose you launch a model rocket with an upward starting velocity of v ft/s. You can use the equation to find the rocket's altitude, h represents height in feet, t seconds after launch and represents initial height. Suppose the upward starting velocity is 315 ft/s and the initial height is 3 ft. When will the rocket hit the ground?
Answer:
The rocket will hit the ground at 64.2 seconds.
Step-by-step explanation:
The time at which the rocket will hit the ground can be calculated using the following equation:
[tex] Y_{f} = Y_{0} + V_{0}y*t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]Y_{f}[/tex]: is the final height = 0
[tex]Y_{0}[/tex]: is the initial height = 3 ft
[tex]V_{0}[/tex]: is the initial speed = 315 ft/s
t: is the time =?
g: is the gravity = 9.81 m/s²
[tex] 3 + 315*t - \frac{1}{2}9.81*t^{2} = 0 [/tex]
Solving the above quadratic equation for t, we have the following values:
t₁ = -0.0095 s
t₂ = 64.2 s
Taking the positive value, we have that the rocket will hit the ground at 64.2 seconds.
I hope it helps you!

Tyler wants to use $300 he has saved to buy a new guitar and join a music club. The guitar costs $140. The music club has a $25 membership fee, and for $11.95 per month, members can download 30 songs.
Tyler can afford the music club membership for [blank]
months, after which he will have [blank]
left.
Answer:
1. About 11 months
2. 3.55$ would be left
Step-by-step explanation:
1. 300-140=160
160-25=135
135/11.95=11.297
2. 11.95x11=131.45
131.45+25=156.45
156.45+140=296.45
300-296.45=3.55

Answer:
The number of apples in the 12th bag is 9
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum{x_i}}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the value of n=12 and the mean number of apples in each bag (8), thus:
[tex]\displaystyle 8=\frac{\sum{x_i}}{12}[/tex]
Multiply by 12
[tex]\sum{x_i}=96[/tex]
This means the sum of all the values is 96. If we add the existing values from the table, considering their frequency, we have:
[tex]6*1+7*4+8*2+9*3+10*1=87[/tex]
Note the sum should be 96, so the 12th bag must have 96-87=9 apples
The number of apples in the 12th bag is 9

Consider the graph of f(x) = 2x 3 – 3x 2 – 14x.
On a coordinate plane, a graph increases through (negative 2, 0) to (negative 1, 10), decreases through (0, 0) to (2, negative 24), and then increases through (3.5, 0) through (4, 20).

10+6x = 15+9x-3x
is this one solution, no solution, or multiple solution if one of 2 please tell me what is x
Answer:
No solution
Step-by-step explanation:
Let's solve this equation to see if there are any solutions.
First we need to simplify it;
10 + 6x = 15 + 9x - 3x
Combine like terms:
6x - 9x + 3x = 15 - 10
0x = 5
0 = 5
Zero cannot be equal to 5, so there is no solution
