How do you Estimate the Product of Decimals and Whole
Numbers
Estimate each product. You can round to the greatest position or
use compatible numbers. Show how you estimated.
Answer:
1) 8.5
2) 60
3) 69.3
4) 6.8
5) 3.6
6) 10.5
Step-by-step explanation:
Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 or 276)

6 Bridesmaids want to make 330 decorations for a wedding. Each
decoration takes about 2 4 minutes to make. How many hours will it take
for each person to make all the decorations?
Answer:
about 3.21 hours each
Step-by-step explanation:
First divide 330 by 6 since there are six people.
Every person needs to do 55 decorations.
I would take the average of 2-4 minutes and multiply it by 55.
55 x 3.5 = 192.5 minutes
to convert to hours divide by 60.
192.5 / 60 = 3.21
which is equivalent to the expression 2/3(d + 6)

The school book fair has a great deal on the last day of the book fair! The first two books you buy costs a total of $7 and then each book purchased after that costs $3.50. How much do you owe if you purchase 8 books?
Answer:
28$
Step-by-step explanation:
You subtract 2 from 8 which is 6, you then multiply 6 times 3.50. Then add 7, which you get 28$
Answer:
$28.000000000000000000000000000000000
Step-by-step explanation:
Lol they're called, wait, what are they called again? ;-; no no I really forgot this time.
Onto the Problamo
We purchase 8 books in total. The first two books cost $7. So that 2/8 books purchased. now we need to purchase 6 more. Because It says: $3.50 per book, we do 3.50*6 or 3.50+3.50+3.50+3.50+3.50+3.50. so 7$ from the 2 books from the first statement plus $21 from the leftover 6 books.
7+21=28$
so I owe the school book fair $28 in the end
A 6-ounce drink costs $2.16. What is the unit rate (cost / 1 oz.)?
Answer:
im pretty sure its 0.36
Step-by-step explanation:
The unit rate or cost of one ounce of the drink is $0.36.
Given that:
A 6-ounce drink costs $2.16.
It is required to find the unit rate.
Now, the unit rate can be defined as the quantity of something with respect to another quantity.
Here, the unit rate is the cost of the drink per ounce of the drink.
Cost of 6-ounce drink = $2.16
Let the cost of one ounce drink = x
Here, the proportional concept can be used.
6 / 2.16 = 1 / x
Cross multiply.
6x = 2.16
Divide both sides by 6.
x = 0.36
Hence the unit cost is $0.36.

Which division problem is represented with this model? 14÷3 15÷3 13÷2 15÷4
Answer:
The division model is 15 ÷ 3
Step-by-step explanation:
Required
Interpret the division model
A division model is of the form: Dividend ÷ Divisor
In the attached figure (in the question), there are 5 vertical partitions.
This vertical partitions represents the result of the model
Also from the question attachment;
The horizontal partitions on the left, if traced to the right side of the diagram means that each vertical partition is divided into 3 and this represents the divisor of the model.
So, we have:
[tex]Divisor = 3[/tex]
To get the quotient of the model, I'll make use of my attached file.
Counting the number of boxes, we can see that there are 15 boxes in total.
So, we have:
[tex]Dividend = 15[/tex]
Hence, the division model is: 15 ÷ 3

The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tests ​negative, given that he or she has the disease.
Answer:
[tex]Probability = 0.0470[/tex]
Step-by-step explanation:
This question has missing detail. (See attachment for the data)
Required
Determine the probability that a selected individual who has the disease test negative.
This type of probability is referred to as conditional probability.
First, we need to get the number of individuals who have the disease.
[tex]Disease =142 + 7[/tex]
[tex]Disease =149[/tex]
Next, we list out the number of individual who have the disease but is negative.
[tex]Negative = 7[/tex]
The probability is then calculated as:
[tex]Probability = \frac{Negative}{Disease}[/tex]
[tex]Probability = \frac{7}{149}[/tex]
[tex]Probability = 0.04697986577[/tex]
[tex]Probability = 0.0470[/tex] (approximated)
Calculate the area of a triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2). A. 14 square units b. 15 square units c. 18 square units d. 20 square units
Answer:
15
Step-by-step explanation:
took the test
The area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.
What is a triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle ABC with altitude CD.
The coordinates for the triangle are A (-3, -4), B (-6, 2), C (0, 0), and
D (-4, -2)
From the figure, the distance between C and D will be the height of the triangle:
We can calculate the distance between the points by using the distance formula:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
h = √20
b = √45
Area of triangle = (1/2)bh = (1/2)√20×√45
= (1/2)30
= 15 square units
Thus, the area of the triangle is 15 square units if the triangle ABC with altitude CD, given A (-3, -4), B (-6, 2), C (0, 0), and D (-4, -2) option (b) is correct.

in how many ways can 7 of 10 mice can be arranged in a row for geentics experiments?
Answer:
Number of arrangements is 604800
Step-by-step explanation:
Given
[tex]Mouse = 10[/tex] --- Total
[tex]Mouse = 7[/tex] --- Arrangement
Required
Determine the number of ways
Since, it is an arrangement, then we make use of the following permutation formula to answer this question.
[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]
Where
[tex]n = 10[/tex]
[tex]r = 7[/tex]
So:
[tex]^nP_r = \frac{n!}{(n-r)!}[/tex]
[tex]^{10}P_7 = \frac{10!}{(10-7)!}[/tex]
[tex]^{10}P_7 = \frac{10!}{3!}[/tex]
[tex]^{10}P_7 = \frac{3628800}{6}[/tex]
[tex]^{10}P_7 = 604800[/tex]
Hence, number of arrangements is 604800
