Evaluate (whith steps) -3 - 5 (8 + 4) + 16 - 32
Answer:
Using the order of operations (PEMDAS), we evaluate the expression as follows:
First, we perform the operations inside the parentheses: 8 + 4 = 12.
Next, we multiply 5 by 12: 5(12) = 60.
Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.
Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.

what are the oz and which one is better?
Answer:
Step-by-step explanation:
13oz bottle of dish soap sells for 2.34
Answer: hope this helps ♡
The unit price of the 13 oz bottle is $0.18 per oz
The unit price of the 30 oz bottle is $0.53 per oz
The 13 oz bottle for $2.34 is a better deal.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
13 oz = $2.34
13 oz bottle is $? per oz
[tex]\frac{2.34}{13}[/tex] = 0.18
1 oz = $0.18
(double check: 0.18×13=2.34)
30 oz = $15.90
30 oz bottle is $? per oz
[tex]\frac{15.9}{30}[/tex] = 0.53
1 oz = $0.53
(double check: 0.53×30=15.9)
The 13 oz bottle for $2.34 is a better deal.

zoey is using an open number line. she wants to find 232+578. which addend should she place on the number line to start? explain
Answer:
To add 232 and 578, Zoey should start by placing the smaller addend, which is 232, on the number line. She can then add the larger addend, which is 578, by counting up from 232.
Here's how Zoey can do it:
Draw an open number line and label it from 0 to 800, with tick marks for every 100 units.Mark the starting point for 232 on the number line.To add 578, Zoey can count up from 232 by 100s until she reaches 578.She can count 100, 200, 300, 400, 500, and 600, which brings her to 832.However, she only needs to add 578, so she can stop at the point on the number line labeled 810.Therefore, Zoey should place 232 on the number line to start adding 232 and 578.
Zoey should place the addend 232 on the number line to start.
What is Number Line?A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.
Number line has numbers 232 and 578 marked at different points.
In order to find the sum of these two addends, we have to place the smaller addend at the start.
Here 232 is the smaller addend
578 is the larger addend.
Start with the smaller one, 232.
Then add the larger addend to it.
Hence the addend that should be started with is 232.

A bowl contains red and brown marbles. A scoop of marbles that is a representative sample contains 18 red marbles and 27 brown marbles.
a. Can you predict if there are more red marbles or more brown marbles in the bowl? Explain.
b. There are 850 marbles in a bowl. If you pick one marble from the bowl, are you more likely to pick a red marble or a brown marble?
a. Based on the information provided, it is not possible to predict if there are more red marbles or more brown marbles in the bowl, because the sample size is not given. It is possible that the sample is not representative of the overall population of marbles in the bowl, and thus the sample proportions may not accurately reflect the actual proportions of red and brown marbles in the bowl.
b. To determine the probability of picking a red or brown marble from the bowl, we need to know the overall proportion of red and brown marbles in the bowl. From the given sample, we know that the proportion of red marbles is 18/45 or 0.4, and the proportion of brown marbles is 27/45 or 0.6. Assuming that these proportions are representative of the overall population of marbles in the bowl, we can predict that we are more likely to pick a brown marble (with a probability of 0.6) than a red marble (with a probability of 0.4) if we pick one marble from the bowl.

PLEASE HELP ME ASAP!! Charlie is practicing the long jump. His first jump is a distance of 16[tex]\frac{5}{6}[/tex] feet. His second jump is a distance of 18 [tex]\frac{2}{3}[/tex] feet. How much longer is Charlie's second jump? Please explain!!!
Answer:
[tex]2 \frac{1}{6} [/tex]
Step-by-step explanation:
So we have
[tex]16 \frac{5}{6} \: and \: 18 \frac{2}{3} [/tex]
If you have the same denominator for each fraction, you'd be able to subtract the numerators like regular subtraction
Seeing the 2/3, if we multiply each number by 2, you get
[tex]18 \frac{4}{6} [/tex]
Now you have 5/6 and 4/6. Since they both have 6 at the bottom, you can subtract 5 and 4.
5-4=1
Now you have 1/6.
Then you can just subtract the 18 and 16 like normal giving you 2.
After we combine our numbers, we get 2 1/6. Hope this helps

Answer:
Part A:
6 feet
Part B:
Around 9.17 feet
Part C:
Around 3 feet
Step-by-step explanation:
Part A:
The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).
Part B:
Using the same method, but with different measurements:
(a^2 + b^2 = c^2)
(16 + b^2 = 100)
(b^2 = 84)
(b = 9.17)
Part C:
The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)

Answer: (-1, 3)
Step-by-step explanation:
x = -1
y = 3
3 = -1 + 4
-1 + 3 = 2
Answer:
(-1, 3)
Step-by-step explanation:
One way to solve this is to simply plug the points into the equations, and see if both equations hold true.
(1, 5)
5 = 1 + 4 is true
However
1 + 5 = 2 is not true, therefore this isn't the answer.
(0, 2)
2 = 0 + 4 isn't true so we can move on to the next point.
(-1, 3)
3 = -1 + 4 is true
and
-1 + 3 = 2 is also true
Therefore, (-1, 3) is the answer.
3) Find the discounted price, to the nearest cent, for a portable CD player that sells for $59.95 and is on sale for 30% off.
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:
42 dollars
Step-by-step explanation:
$59.95-30% is 41.965. We round this to 42 dollars.
If it sells for 59.95, and it's on sale for 30% off, you can use this equation to find the new, discounted price:
59.95 x 0.70 (the 0.70 resembling 100-30%)
The answer of this equation is 41.965, rounded to 41.97.
Percent of change: about 30% (29.9917% decrease)
A local animal rescue has 20 people that help foster pets while they are
waiting on finding their homes. They expect to gain two additional people
willing to foster animals each month. The amount of animals in need of
homes in the community is currently 10 and growing at a rate of 15% per
month. When will the amount of homeless pets surpass the amount of foster
homes available?
A) Write the two functions that represent this situation.
B) Create a table of values for x=0 to x=13.
C) Approximate the solution(s). Why is this the approximate solution?
D) Using graph paper (and the table of values), sketch the situation to
show the exact solution.
Answer:
A) Let f(x) represent the number of foster homes available after x months, and let g(x) represent the number of homeless pets after x months.
f(x) = 20 + 2x (since 2 additional people are expected to foster each month)
g(x) = 10(1.15)^x (since the number of homeless pets is growing at a rate of 15% per month)

Violet's car used 5/6 of a gallon to travel 17 1/2 miles. At what rate does the car use gas, in miles per gallon?
First, reason down from 5/6 to 1/6 Enter all values as fractions (proper or improper) or whole numbers. You will need to convert mixed numbers to improper fractions.
Answer:
Therefore, the car uses gas at a rate of 21 miles per gallon.
Step-by-step explanation:
If Violet's car used 5/6 of a gallon to travel 17 1/2 miles, we can find the rate at which the car uses gas (in miles per gallon) by dividing the distance traveled by the amount of gas used.
To do this, we need to convert the mixed number 17 1/2 to an improper fraction:
17 1/2 = 35/2
So, the rate at which the car uses gas is:
(35/2) miles ÷ (5/6) gallons
To divide by a fraction, we can multiply by its reciprocal:
(35/2) miles ÷ (5/6) gallons = (35/2) miles x (6/5) gallons
Simplifying, we get:
(35/2) x (6/5) = (35 x 6)/(2 x 5) = 210/10 = 21
Therefore, the car uses gas at a rate of 21 miles per gallon.
