joe has read 30 % of a book. He has 63 more pages to finish. How many pages are there in the book?
Answer:
90 pages
Step-by-step explanation:
30% complete
70% to go = 63 pages
t = total number of pages
0.7t = 63
∴ t = ⁶³/₀.₇
⁶³/₀.₇ = 90
An underwriter is analyzing the heights of his clients. He categorizes 35% as tall, 40% as medium height, and 25% as short. He then randomly picks two clients (from his very large client base). What is the probability that neither is tall and at most one is medium height
Answer:
0.2625 = 26.25% probability that neither is tall and at most one is medium height.
Step-by-step explanation:
Desired outcomes:
Short - Short
Short - Medium
Medium - Short
Probability of two short:
25% are short, so:
[tex]P(A) = (0.25)^2 = 0.0625[/tex]
Probability of short medium or medium short
25% short, 40% medium. So
[tex]P(B) = 2*0.25*0.4 = 0.2[/tex]
What is the probability that neither is tall and at most one is medium height?
[tex]P = P(A) + P(B) = 0.0625 + 0.2 = 0.2625[/tex]
0.2625 = 26.25% probability that neither is tall and at most one is medium height.

A researcher’s garden contains 90 sweet pea plants,
which have either white or purple flowers. About 70 of the plants have purple flowers, and about 20 have white flowers.
Would you expect that one plant randomly selected from the garden will have purple or white
flowers? Explain
Hey buddy I am here to help!
No, because according to theoretically probability most of the sweet pea plants have purple flowers causing that one plant to have the probability purple flowers more than of the white flowers!
Here is teh mathematical way-
total plants = 90
purple flowers = 70
white flowers = 20
higher probability of flower = 70/90

A tank contains 1000L1000L of brine with 20kg20kg of dissolved salt. Pure water enters the tank at a rate of 15L/min.15L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. Answer the following questions. 1. How much salt is in the tank after tt minutes
Answer:
there is 15[tex]e^{ \frac{-t}{100}[/tex] amount of salt in the tank after t minute.
Step-by-step explanation:
Given the data in the question;
tank contains 1000L of brine with 20kg of dissolved salt, Pure water enters the tank at a rate of 15L/min.
How much salt is in the tank after t minutes.
Now,
let x represent the amount of salt after t minutes,
so
x(0) = 15
dx/dt = rate in - rate out
Now, since the water entering is pure, the rate in is 0
rate out will be; x/1000 × 10 kg
∴
dx/dt = -x/100
[tex]\frac{1}{x}[/tex]dx = -[tex]\frac{1}{100}[/tex]dt
∫[tex]\frac{1}{x}[/tex]dx = -[tex]\frac{1}{100}[/tex]∫1dt + c
lnx = -[tex]\frac{t}{100}[/tex] + c
Now since x(0) = 15
ln15 = c
lnx = -[tex]\frac{t}{100}[/tex] + ln15
x = [tex]e^{ \frac{-t}{100} + ln15[/tex]
x = 15[tex]e^{ \frac{-t}{100}[/tex]
Therefore, there is 15[tex]e^{ \frac{-t}{100}[/tex] amount of salt in the tank after t minute.

Answer:
7. [tex]BC=22[/tex]
8. [tex]EF=8[/tex]
Step-by-step explanation:
7.
It is given that triangle (ABC) is similar to triangle (DEF). This means that triangle (DEF) is a scaled version of the triangle (ABC). Between these two triangles, there is a ratio. This ratio referred to as the ratio of similitude, is a factor that one multiplies a side of the triangle by, to get the length of the corresponding side in the other triangle. This number can be found by dividing the corresponding sides in the triangle.
As per the given picture, side (AB) corresponds to side (DE). Therefore divide side (AB) by (DE) to find the ratio of similitude,
[tex]\frac{AB}{DE}=\frac{10}{5}=2[/tex]
Multiply side (EF) by the ratio of similitude to find the length of its corresponding side (BC).
[tex]2(EF) = 2(11) = 22[/tex]
[tex]BC=22[/tex]
8.
The triangles (ABC) and (DEF) are similar. One can use the same logic applied to the last problem to solve this problem. For further reference, read the intro written to explain the process used to solve the problem (7).
One can see that sides (AB) and (DE) are corresponding sides, divide (DE) by (AB) to find the ratio of similitude;
[tex]\frac{DE}{AB}=\frac{4}{6}=\frac{2}{3}[/tex]
Now multiply this number by side (BC) to find the length of the corresponding side (EF);
[tex](BC)*\frac{2}{3}=EF\\12*\frac{2}{3}=EF\\8=EF[/tex]

2x = 10
x = 5

Cora's dad has asked Cora and her little brothers to rake the leaves in their yard. They rake all afternoon and fill a number of bags with leaves. Then, when Cora isn't looking, her brothers empty 6 of the bags to make a giant leaf pile! Cora is frustrated that only 5 bags of leaves remain. What equation can you use to find the total number of bags b that Cora and her brothers fill with leaves?
Answer:
11
Step-by-step explanation:
because they empty 6 bags and there are 5 bags left to that is 11 all together
The total number of bags of leaves b is given by the equation b = 11 bags
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the total number of bags be = b
The number of bags emptied by Cora's brother = 6 bags
The number of bags left with Cora = 5 bags
So , the equation will be
The total number of bags b = number of bags emptied by Cora's brother + number of bags left with Cora
Substituting the values in the equation , we get
The total number of bags b = 6 + 5
The total number of bags b = 11 bags
Therefore , the value of A is 11 bags
Hence , the number of bags of leaves is 11 bags

There are 13 books on a shelf. 8 of these books are new. The rest of them are used. What is the ratio? (PICTURE)
Answer:
(a) 5:13
(b) 5:8
Step-by-step explanation:
There are 13 books in all.
8 books are new.
13 - 8 = 5 books are used.
Ratio of used books to all books: 5 used books : 13 books in total.
Ratio of used books to new books: 5 used books : 8 new books.
~
Answer
A= [tex]\frac{5}{13}[/tex] Or 5:13
B= [tex]\frac{5}{8}[/tex] or 5:8
Step-by-step explanation:
the question asked for you to show the ratio for the number of used books compared to the total number on the shelf. Since it tells us that 8 of the 13 books are new that would mean that the other 5 books that are on the shelf with the 8 new ones would be used. Then you just put it in a ratio, which if im remembering correctly from when i learned this it just looks like a fraction basically. Same goes for the second question except you are just putting the number of used books to the number of new books in ratio form. Hope this helps and also if you need help learning ratios i gotchu covered :)
a) How does the distance traveled and time elapsed compare for Carrie and Kevin as they traveled from mile marker 225 to mile marker 230?
Answer:
They travelled the same distance and they spent the same amount of time from the 225 marker to 230 marker.
Step-by-step explanation:
Given
See attachment for graph
Required
The relationship between distance and time travelled by Kevin and Carrie
The straight line represents Kevin's journey while the curve represents Carrie's
From the graph, we can see that the straight line and the curve both start at the origin (0,0) and they both end at the same point (17,5)
Point (17, 5) represents the 230 marker (i.e. 225 + 5 - 230)
Since the line and the curve meet at this point, then they travelled the same distance and they spent the same amount of time.
