Question 1 (Multiple Choice Worth 5 points)
(01.02 MC)
Which of the following correctly simplifies the expression?

Answer:

6.44

Step-by-step explanation:

Since, there is a 4 in the hundredths and in the thousandths place there is a 3, then the answer should round off to 6.44 because you only round the 4 up to a 5 if the number in the thousandths place is 5 or greater.

Hope this helps!

Answer:

1/6 chance

Step-by-step explanation:

It's a 1/6 chance because there are 6 sections and if the lander just happens to land on a solid section which is only 1/6 of the whole circle it would have a 1/6 chance of landing on the solid color.

Given:

A blueprint of a house shows a wall that is 5 inches long.

The blue pretty strong to a scale of 1:60.

To find:

The actual width of the wall in the house.

Solution:

The blue pretty strong to a scale of 1:60.

It means, the dimensions of blueprint to the actual house is 1:60.

Width of a wall in blue print = 5

Let the actual width of the wall in the house be x.

[tex]\dfrac{5}{x}=\dfrac{1}{60}[/tex]

[tex]5\times 60=1\times x[/tex]

[tex]300=x[/tex]

Therefore, the width of the wall in the house is 300 inches.

Answer:

It's around 459. So 460 if need to round

Step-by-step explanation:

So, 40 randomly chosen people do not represent  the whole school, but using the ratio 27:40 you are given in the equation, you can divide the number of students (680) by the surveyed students (40) to get 17. What this means is there is 17 groups of 40 in the school, so to distribute the amount of people who are in a after-school activity, you must multiply 17 x 27 to get the assumption of about 459 kids. Hopefully you understand =)

Answer:

The answer is C.

Step-by-step explanation:

I did the test and got it right. :)

The correct is C = Multiply the first equation by 2 and the second equation by 3.

The elimination method exists utilized to solve a system of linear equations. It is the most widely used and simple method as it concerns fewer calculations and steps. In this manner, we eliminate one of the two variables and test to solve equations with one variable.

if we'll multiply the first equation by 2 and second by 3 we will be able to solve the equation by elimination.

(-3x+2y=16) X 2 = -6x + 4y = 32

(2x+5y=21) X 3 = 6x + 15y = 63

the coeffients of x gets cancelled out on adding the new equations

4y+ 15y = 32+ 63

19y = 95

y= 95/19

G. 7(200)+7(10)

Step-by-step explanation:

First, you would multiply 200 by 7

Once you do that you should get 1400

After that you mulitply 7 by 10

You should get 70

Add 1400 by 70 and there you go your answer 1,470

Answer:

7(200)+7(10)

Step-by-step explanation: it is quite simple.first you look at the number out side of the () and that is the first number of your answer.then you look at the other number and split it into the 100 place and the tenth place.finally you know it is G because you have to have the () in the answer so it is G.

Answer:

"The number of months Megan will wait to sell the gadget."

Step-by-step explanation:

It says in the original question, "She plans to sell it sometime in the future, however, its value depreciates monthly."

This means that the value depends on the number of month she holds on to it. Hence, the variable with which the value is attached, is the number of months.

So in the equation  ,  represents the number of months Megan holds on to the gadget.

Answer:

The monthly depreciation value of the gadget

Answer:

The first plant manufactures 2x + 21 more items daily.

Step-by-step explanation:

Given that:

Production level of plant one = 7x + 19

Production level of plant two = 5x -2

To find the number of items first plant manufactures more than second plant, we will find the difference between production levels.

Difference = (7x + 19) - (5x - 2)

Difference = 7x + 19 - 5x + 2

Difference = 2x + 21

Hence,

The first plant manufactures 2x + 21 more items daily.

Step-by-step explanation:

Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.

Answer:

Answer:

Two possible equations:

[tex]y = x + 1\\y = x - 5\\[/tex]

The system has 0 solution as parallel lines never cross each other.

Step-by-step explanation:

Considering the two lines are parallel, they both have the same slope.

let m be the slope of the two lines:

[tex]y = mx + y_{0}\\y=mx+y_{1}[/tex]

[tex]y_{0}, y_{1}[/tex] are the value on y axis where the two lines cross the axis.

Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.

Answer:

I. Volume = 301.6 cm³ (to 1d.p)

II. CSA = 188.5 cm² (to 1d.p)

Step-by-step explanation:

Given the following data;

Height, h = 8cm

Radius, r = 6cm

Curved length = 10cm

a. To find the volume of the cone

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

Substituting into the equation, we have;

[tex] Volume = \frac{1}{3} * 3.142*6^{2}*8 [/tex]

[tex] Volume = \frac{1}{3} * 3.142*36*8 [/tex]

[tex] Volume = 3.142*12*8 [/tex]

Volume = 301.6 cm³ (to 1d.p)

b. The curved surface area of the cone

[tex] CSA = \pi rl[/tex]

Where;

Substituting into the equation, we have;

[tex] CSA = 3.142*6*10 [/tex]

CSA = 188.5 cm² (to 1d.p)
