Step-by-step explanation:

When the car stops, the speed is zero.

When S = 0, -10t + 45 = 0, t = 4.5.

Hence it will take 4.5 seconds for the car to stop.

Answer:

Step-by-step explanation:

- So first add the 9cm and the 2 cm together, to make 11cm

- Then multiply 11cm with 7cm, which is 77cm

- 77cm² is the area

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer:

116.6

Step-by-step explanation:

Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.

Perimeter (4×Length) = 16.9 cm

Length = 16.9÷4 = 4.225 cm

Area = L² = 4.225² =

Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

Answer:

I do not agree with Talia.

Step-by-step explanation:

This is because they did not simplify the expression correctly. When simplifying this expression you would use the Order of Operations.

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

See attachment for the graph of the equation.

Step-by-step explanation:

Given equation:

\(y=\dfrac{1}{3}x\)

To complete the table, find the corresponding values of y by substituting each given value of x into the equation.

\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)

\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)

\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)

Therefore the completed table is:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

To graph the equation, plot the ordered pairs on the given coordinate plane:

Draw a straight line through the points.  (See attachment).

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Answer:

84

Step-by-step explanation:

Find the area of the above rectangle (10*6 = 60)

Find the area of the middle rectangle (4*3 = 12)

Find the area of the lower rectangle (2*6 = 12)

Add up the areas: 60 + 2(12) = 84

Answer

So, the simplest form of 84:24 is 7:2.

Step-by-step explanation:

Answer:

7:2

If you want to do this yourself, simply do 2/24 which equals 12.  No you take the 84, and divide it by 12, and you get 7.

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

x = 9

Step-by-step explanation:

mean = 5+7+7+x /4 = 7

19+x / 4 = 7

19+x = 28

x = 9

Answer:

For question 1 the answer is 6.

For question 2 the answer is 9

Question 1

In order to find the average of a set of numbers you have to add all the numbers given and then divide the value that you get by the amount of numbers added. In the question you were given 7 numbers therefore, you add all of then and then divide the value you get by 7.

Question 2

To calculate the mean we do as we did above and add all the numbers given then divide the value obtained by the amount of numbers added. However in this question we are missing a number so we substitute the value and call it *x*. So, (5+7+7+x)/ 4 = 7. we cross multiply to get 4x7 which is 28. The new equation would then be: (5+7+7+x) =28, you then group the like terms to get: 5+7+7-28 = x. Therefore x is equal to 9. Meaning that the forth number is *9*

Answer:

1) m = 1/2 (E)

2) m = (-8 - (-12))/(1 - (-1)) = 4/2 = 2 (C)

3) m = (-3 - (-6))/(-4 - 2) = 3/-6 = -1/2 (H)

4) m = -2 (A)

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.

Step-by-step explanation:

So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.

Where, the original price is the total price. So, the means that it is the whole price.

Just to help:

Answer - Part B: The original cost of the jeans are $80.

Step-by-step explanation:

If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.

So, see? 30% of 80 is $24.
