Problem 1: Evaluate each expression below. (You can take a picture your work and upload to this slide)
B. -0.3(4+(-1.6))-6 ½
Answers
Answer:
=
107/135
(Decimal: 0.792593)
Step-by-step explanation:
Answer:
a. 19/20
B. -5.78
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal. i.e. \(\frac{-\frac{2}{3} }{-\frac{8}{9} } =-\frac{2}{3} *-\frac{9}{8} = \frac{3}{4}\) to add to 1/5, change both denominators to 20.
\(\frac{3}{4} * \frac{5}{5} = \frac{15}{20}\)
\(\frac{1}{5} *\frac{4}{4} =\frac{4}{20}\)
\(\frac{15}{20} +\frac{4}{20} = \frac{19}{20}\)
B. Convert all to decimals, then work from the inside out because of the parentheses. -1.6 + 4 = 2.4, 2.4(-0.3) = -0.72, -0.72 - 6.5 = -5.78

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.

Answers
Answer:
The answer is 43 meters below the water.
Step-by-step explanation:
Ana is 35 meters below the water's surface, so if Jesse is 8 meters below her, you would add 8 to 35 and end up with 43 meters below the surface of the water.

For a dilation centered at the origin with a scale factor of 3/2:
(a) original coordinates → final coordinates
R (-4,6) → R' (-6,9)
S (6,2) → S' (9,3)
T (-6,-4) → T' (-9,-6)
(b) (x, y) → ((3/2)x, (3/2)y)
How to determine a dilation mapping?To determine a dilation mapping, follow these steps:
Identify the center of dilation. This is the fixed point around which the dilation occurs.Determine the scale factor. The scale factor determines how much the image is stretched or shrunk. It can be a positive or negative number, but it cannot be zero.Apply the scale factor to each coordinate. To do this, multiply each coordinate by the scale factor, with the center of dilation as the origin.For example, if the center of dilation is (2, 3) and the scale factor is 2, the dilation mapping can be expressed as:
(x, y) → (2(x-2), 3(y-3))
This means that every point (x, y) is transformed into the point (2(x-2), 3(y-3)) after the dilation.

Customers who buy a fidget toy sold by an online store can give the fidget toy a rating from 1 star to 5 stars. The frequency able shows the number of 1-star, 2-star, 3-star, 4-star, and -star ratings.
Answers
Answer:
The customer ratings for the fidget toy sold by the online store can be represented using a frequency table. The table displays the frequency or count of each rating category, ranging from 1 star to 5 stars. Here's an example of how the frequency table might look:
Rating Frequency
1 star 10
2 stars 20
3 stars 30
4 stars 15
5 stars 25
In this example, the frequency table indicates that there were 10 customers who rated the fidget toy as 1 star, 20 customers who rated it as 2 stars, 30 customers who rated it as 3 stars, 15 customers who rated it as 4 stars, and 25 customers who rated it as 5 stars.
By organizing the ratings into a frequency table, it becomes easier to analyze the distribution of ratings and understand the overall customer satisfaction for the fidget toy.

The price of an item has been reduced by 35%. The original price was $60. What is the price of the item now
Answers
Answer:
Step-by-step explanation:
$60=100%
A 35% reduction is the same as multiplying by 0.65(1-0.35).
$60*0.65=$39
100%=60
10%=6
(6x3) 30%=18
(6÷2)5%=3
(18+3)35%=21
60-21= $39

Moving an object at a faster speed is doing more work than moving an object at a slower speed (same distance for both). True or false?

false
Step-by-step explanation:
explanation:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
