Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.
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)

Which expression represents the sum of 2/3m - 1 1/6 and 5/6m - 1 1/3?
HOW DO I DO THIS??????
Answer:
-m+15/6
2/3m-5/3m-5/2
Answer: 1 5/6m - 2 1/2
Step-by-step explanation:
(2/3m - 1 1/6) + (5/6m - 1 1/3)
2/3m X 2 = 4/6m
4/6m + 5/6m = 11/6m=1 5/6m
-1 1/3 X 2 = -1 2/6
-1 2/6 - 1 1/6 = -2 1/2
1 5/6m - 2 1/2
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.

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! :)
What is the answer to this question
Answer:
y = 8/x
Step-by-step explanation:
The rule that describes a nonlinear function is [y = 8/x.]
A nonlinear function is a mathematical function that does not have a constant rate of change. In other words, as you move along the graph of a nonlinear function, the rate of change is not constant.
In this case, the function y = 8/x is nonlinear because the rate of change of y with respect to x is not constant. For example, when x is small, y takes large values, but when x is large, y takes small values. This type of relationship is not linear and therefore it is nonlinear.
The other rules are linear functions. The rule x + y = 100 can be rearranged to y = -x + 100, which is a linear function. The rule 9 = 11x - y can also be rearranged to y = 11x - 9, which is a linear function. Finally, the rule x = y represents a line with slope 1 passing through the origin, which is also a linear function.
Answer:
y = 8/x

2. Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day that the fair arrives at the fairground and then continues to work on finishing the setup for about a week to have the rides ready to go in time for the opening of the fair. The scatter plot shows Anika's setup time on different days and the linear model for the data.
Annika’s Setup Time
Time (Days)
(a) What is the equation of the line, written in slope-intercept form? Show how you determined the equation. ( also find the slope and equation in point slope form)
(b) Anika arrived on Day 0. Based on the linear model you created in Part A, predict how long Anika worked on Day 0.
(c) Approximately how much did her setup time decrease per day?
Answer:
(a) The equation of the line, written in slope-intercept form, is y = -5x + 20. This can also be written in point slope form as y - 20 = -5 (x - 0). The slope is -5 and this was determined by looking at the trendline on the scatter plot.
(b) Based on the linear model created in Part A, Anika worked for 20 hours on Day 0.
(c) Anika's setup time decreased by approximately 5 hours per day based on the linear model.
Answer:
Step-by-step explanation:

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.

All triangles have a sum degree measure of 180.
We know ∠B, which is 39.8.
∠A is known as well, the little box at the corner indicates a right angle, which means it has a degree of 90.
To find ∠C, we can construct a formula to find the unknown value.
1. 180 = ∠A + ∠B + ∠C Isolate ∠C.
2. 180 - ∠A - ∠B = ∠C
3. 180 - 90 - 39.8 = ∠C
4. 50.2 = ∠C
Therefore, angle C is 50.2 degrees. The other information is written to throw you off.
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

y = 64
y = 72
The answer to this equation is Y = 32
Answer:
y=18
Step-by-step explanation:
3/4y=24
First you would multiply 3 by 24 which is 72 Then you would divide 72 by 4 which is 18 so y=18
