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)

Answer:

500 grams.

Step-by-step explanation:

1kg = 1000grams.

0.5 * 1000 = 500grams.

Answer:

500 grams

Step-by-step explanation:

Because 1000grams = 1kg so 100 = 0.1

So to get this you multiply 0.5 with 1000

Answer:

x=13

Step-by-step explanation:

ok so let x+y=22

--------------------------------------------------------

x and y are the 2 unkown Number

-------------------------------------------

x-y=4

their difference is 4

----------------------------------

add both equations

(x+y=22)

+(x-y=4)

------------------------------

y's cancel out

-----------------------

2x=26

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.

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.

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.

[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)

Answer:

$51.75

Step-by-step explanation:

The meal cost $45. $45 is 100% of the cost. She wants to leave a 15% tip, so add 15% to 100%.

15% + 100% = 115%

She will pay 115% of $45.

115% of $45 = 1.15 * $45 = $51.75

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

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

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
