Answer: There are 175 pages in the book.
Step-by-step explanation:
If Elena read 20 more pages than Andre and she read 55 pages, to find out how much Andre read you have to:
55-20= the pages Andre read
55-20=35
Andre read 35 pages.
If Andre read 1/5 of the book, then to find how many pages are in the book, you have to multiply 35 x 5. (Multiply by the reciprocal)
35 x 5= 175
There are 175 pages in the book.
1.0 is what percent of 3.5
Answer:
28.57%
Step-by-step explanation:
Let the required percent be x
1.0 is what percent of 3.5 is written as;
1.0 = x% of 3.5
1.0 = 0.01x * 3.5
0.01x = 1/3.5
0.01x = 0.2857
x = 0.2857/0.01
x = 28.57%
Hence 1.0 is 28.57% of 3.5

Case 1 = 4 blocks case 2 = 9 blocks case 3 =16 blocks. How many blocks are need for the 9th case?
9514 1404 393
Answer:
100
Step-by-step explanation:
4 = 2² . . . case 1
9 = 3² . . . case 2
16 = 4² . . . case 3
The number of blocks is the square of the number 1 greater than the case number. For case 9, the number of blocks is (9+1)² = 10² = 100.
100 blocks are needed for the 9th case.

Find the area of a rectangle with the following side lengths:
Width: 3x - 4
Length: 3x + 2
9514 1404 393
Answer:
9x² -6x -8
Step-by-step explanation:
The area is the product of length and width.
A = LW
A = (3x +2)(3x -4) = 3x(3x -4) +2(3x -4)
A = 9x² -12x +6x -8
A = 9x² -6x -8 . . . area of the rectangle

Cafe Cookies
Fraction Cafe is known for its delicious raisin cookies. On the average, ninety-six
cookies are sold each day. The raisin cookie recipe calls for two and one-half cups of
raisins per batch. One batch makes eight dozen cookies. How many cups of raisins are
needed to make enough cookies for one week? Show all your mathematical thinking.
Answer:
i need points so im r
sorry
Answer:
First of all this doesn't seem like a college question but- kay- the answer is 17 and a half cups of raisins.
Step-by-step explanation:
First of all, we need to find how many cookies are in each batch. A dozen is 12, meaning that we do 8 times 12 to see how many cookies are in each batch. 8 times 12 equals 96. This means that Fraction Cafe only makes 1 batch of cookies a day. This makes the following question simple, all we need to do is multiply how many cups of raisins it takes to make one batch, which is 2 and one half, and multiply that by 7 because there are 7 days in a week. First I converted the fration into a decimal making the number 2.5 then, I used long multiplication and moved the decimal from the 2.5 over the the right 1 place. This now makes it 25 times 7. If you know your money values, you could just count 7 quarters because quarters are 25 cents (assuming you use a currency with quarters). 7 quarters are equal to $1.75 or in our case, just 175. But we're not done yet. Remember that decimal point that we moved out of the way? We have to move it back now, meaning that since we moved the decimal 1 place to the right, we have to move it 1 spot to the left making the answer 17.5, or 17 and one half.

Give an example of a rate that is not a unit rate. Explain your choice
Answer:
A unit rate is a rate that has a denominator of 1. For example the Rate could be 48 kids per 4 classrooms. The unit rate for this would be 12 kids per 1 classroom. The denominator should always be one.

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50. if an applicant is randomly selected, find the probability of a rating that is between 200 and 275.
Answer:
0.4332 = 43.32% probability of a rating that is between 200 and 275.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50
This means that [tex]\mu = 200, \sigma = 50[/tex].
Find the probability of a rating that is between 200 and 275.
This is the pvalue of Z when X = 275 subtracted by the pvalue of Z when X = 200. So
X = 275
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{275 - 200}{50}[/tex]
[tex]Z = 1.5[/tex]
[tex]Z = 1.5[/tex] has a pvalue of 0.9332
X = 200
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{200 - 200}{50}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a pvalue of 0.5
0.9332 - 0.5 = 0.4332
0.4332 = 43.32% probability of a rating that is between 200 and 275.

1.2
Answer:
Y-intercept: (0,-0.7)
X-intercept: (-1.2,0)
Explanation:
The Y-intercept is the spot where the line crosses the Y axis (the vertical axis). This always occurs where X=0. For this problem the Y value at this point is -0.7. So, for the coordinates (X,Y) X is 0 and Y is -0.7 so it is (0,-0.7)
The X-intercept is the spot where the line crosses the X axis (the horizontal axis). This always occurs where Y=0. For this problem the X value at this point is -1.2. So, for the coordinates (X,Y) X is -1.2 and Y is 0 so it is (0,-0.7)
1 The graph shows the relationship between the weights of 5 packages and the shipping charge for each package. Is the relationship represented by the graph a function? Explain. I
Answer:
Step-by-step explanation:
Yes, each input value is paired with only one output value.
The function represent the given graph is f(x)=0.67x+1.83.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the graph, the coordinate points are (1, 2.5) and (2.5, 3.5)
Here, slope m=(3.5-2.5)/(2.5-1)
= 1/1.5
= 0.67
Substitute m=0.67 and (x, y)=(1, 2.5) in y=mx+c, we get
2.5=0.67+c
c=1.83
Substitute m=0.67 and c=1.83 in y=mx+c, we get
y=0.67x+1.83
Therefore, the function represent the given graph is f(x)=0.67x+1.83.
