Find the area of a parallelogram....

Answers

The area of a parallelogram is ...
A = bh
Substituting the given values, you have
A = (3x +5)(7x -1)
We presume you want the product multiplied out. Use the distributive property for that.
A = 3x(7x -1) +5(7x -1)
A = 21x² -3x +35x -5
A = 21x² +32x -5

The area of the parallelogram is 21x² +32x -5.

Given: KLMN is a trapezoid, KF =10 MF ║ LK AKLMF = AFMN Find: KN

Answers

Final answer:

The question mixes physical and geometric concepts without a clear relationship or sufficient details to calculate the length of KN in the trapezoid KLMN, making it difficult to provide a step-by-step solution.

Explanation:

The question appears to involve various mathematical and physical concepts, most notably relating to trapezoid geometry and principles of force and motion. However, the specific information provided does not directly lead to a clear method for finding the value of KN in a trapezoid given the other conditions mentioned. It mixes principles from physics, particularly force equations, with geometric properties of trapezoids without presenting a typical geometry problem's clear setup or goal.

Normally, to solve for the length of a side in a trapezoid like KN, one would use properties of trapezoids (e.g., parallel sides, angle properties, or potentially the Pythagorean theorem if right angles are involved). However, the information given mixes unrelated physical equations (such as the force equation F = ma and friction models) with geometric figures without presenting a coherent relation between them.

Without additional specific geometric information or a clearer connection between these physical principles and the geometry of trapezoid KLMN, providing a step-by-step solution for finding KN is not feasible. It is advisable to request more specific details or clarification on how these concepts are supposed to interact within the context of the problem.

Kristen invests $5,745 in a bank. The bank pays 6.5% interest compounded monthly. How long must she leave the money in the bank for it to double? Round to nearest tenth of a year.

Answers

To solve this we are going to use the compounded interest formula: [tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
where
[tex]A[/tex] is the final amount
[tex]P[/tex] is the initial investment
[tex]r[/tex] is the interest rate in decimal form
[tex]t[/tex] is the time in years

We know that initial investment is $5,745, so [tex]P=5745[/tex]. We also know that Kristen wants his investment to double, so [tex]A=2*5745=11490[/tex]. Now, to convert the interest rate to decimal form, we are going to divide the rate by 100%: [tex]r= \frac{6.5}{100}=0.065 [/tex]. Since the interest is compounded monthly, it is compounded 12 times per year: therefore, [tex]n=12[/tex]. Now that we have all the information we need, lets replace the values in our formula and solve for [tex]t[/tex]:
[tex]A=P(1+ \frac{r}{n})^{nt} [/tex]
[tex]11490=5745(1+ \frac{0.065}{12})^{12t} [/tex]
[tex] \frac{11490}{5745} =(1+ \frac{0.065}{12})^{12t}[/tex]
[tex]2=( \frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=ln(\frac{2413}{2400} )^{12t}[/tex]
[tex]ln(2)=12tln(\frac{2413}{2400} )[/tex]
[tex] \frac{ln(2)}{12ln(\frac{2413}{2400} )} =t[/tex]
[tex]t=\frac{ln(2)}{12ln(\frac{2413}{2400} )}[/tex]
[tex]t=10.7[/tex]

We can conclude that she must leave the money for 10.7 years in the bank for it to double.

How do you fully learn your times table and division

Answers

Go over them everyday and let someone test you out from the 1x then 2x and etc

There are simple tricks
•For the 0 everything is 0
•For the 1’s it’s always the same number ur multiplying it by so like 1x2 is just gonna be 2
1x3 is 3 and 1x578 is 578 simple as that.
•For your 2s times tables it’s literally just adding the same number twice so let’s say you have 2x7 which is the same thing as saying 7x2 all you have to do is just add the same number twice so it’s 7+7= 14 lets do another so 5x2 =10 so 5+5=10
•For your 3’s here’s a 2 minute video and it’s supper helpful
https://m.youtube.com/watch?v=ONl323NU0ws
•For the 4s times tables here a quick link https://m.youtube.com/watch?v=UOGuJRzYv0A

https://m.youtube.com/watch?v=-C-e33iVBTM
•For 9s

•For 10s all you have to do is do the same trick as for the 1s but put a zero behind the number so 10x7 is 70 and 10x8 is 80 and 10x9 is 90

There is only so many tricks you can learn so just study it a-little bit because multiplication is veryyyy important.
Multiplying is just adding the same number how ever many times
So let’s say you need to add the number 2 in 9 different times instead of saying 2+2+2+2+2+2+2+2+2=18 you can just simply say 2x9=18 simple Right?

Which of the following shows of the slope of the line and one point on the line?

A. 6/5 and (-3, 1)
B. 5/6 and (1, -3)
C. 5/6 and (-3, 1)
D. -6/5 and (1, -3)

Answers

Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.

NEED HELP ASAP!!! Which graph represents the given inequality? 3x -7y < -21

Answers

Hello there, and thank you for asking your question here on brainly.

Short answer: The first graph, A.

Why?

The equation 3x - 7y < -21 is a dotted line that passes through -7 on the axis. Therefore, the correct answer is A.

Hope this helped you! ♥

Answer:

Step-by-step explanation:

Given the inequality

3x —7y <—21

Make y subject of formulae to know the slope and intercept on y axis

—7y < —3x — 21

Divide through by -7, note the inequalities sign will change since we are dividing with a negative

Then,

y > 3x/7 + 3

Then, the intercept is 3 and the slope is 3/7 when compared to equation of a line y = mx + c

We know that

y is greater than 3x/7 + 3, so the upper part should be shaded since y is greater than 3x/7 + 3

Then, option B and C are wrong since the below is shaded

Let find the intercept on the x axis to know the answer between A and B

I.e. when y = 0

3x —7y <—21

3x < —21

x < -7, then, line should pass through the negative of x and not positive x

So, the first option (A) is correct

C. (8,0,0) (0,28,0) (0,0,4)
D. (8,0,0) (0,-28,0) (0,0,4)

Answers

Since the equation is in 3 variables, there will be 3 intercepts:

1) x-intercept
Where y and z coordinate are zero.
So, we can say
7x + 2(0)-14(0) = 56
So, x = 8 is the x-intercept

2) y-intercept
where x and z coordinate are zero
So, we can write
7(0) + 2y - 14(0) = 56
So, y = 28 is the y-intercept

3) z-intercept
where x and y coordinates are zero
So, we can write
7(0)+2(0)-14z=56
So, z=-4 is the z intercept

Therefore, the correct answer to this question is option B

Answers

It will take 15 days to manufacture 28000 bottles.

We have a factory makes 12 bottles every 2 minutes and makes bottles for 8 hours each work day.

We have to determine the number of days it will take to make 28000 bottles.

What is Unitary Method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to question, we have -

Number of bottles manufactured in 2 minutes = 12.

In 8 hours = 8 x 60 = 480 minutes = 2 x 240 minutes.

Number of bottles manufactured in 1 day = 8 x 240 = 1920 bottles.

Number of days needed to make 28000 bottles = 14.58 = 15 days.

Hence, it will take 15 days to manufacture 28000 bottles.

so what we know is that 15 is the diameter

However the formula to find the area of a circle is A=[tex] \pi [/tex]r²
So to convert the 15 in diameter to a radius you have to do 15÷2,which is equal to 7.5

Now we know that the radius is 7.5.
So what we do now is A=[tex] \pi [/tex]7.5²
Then after we find what 7.5² is we get A=[tex] \pi [/tex]56.25
Then what we do is 3.14×56.25, because pi= 3.14.
So when we do 3.14×56.25, we get 176.625
So the answer is A= 176.6 in²

No, Diego cannot fit 65 smaller cubes into the large box. There will be 5 cubes that cannot be put in.

What is volume?

Volume in math is the amount of three-dimensional space occupied by an object, substance, or closed surface. Volume can be measured by multiplying the length, width, and height of an object or by counting the number of unit cubes it contains.

Given that, Diego has a large box that is 4 feet high, 3 feet wide, and 5 feet long, we need to determine whether he can fit 65 smaller boxes that each have a volume of 1 cubic foot in the large box,

For determining the same, we will find both volume and compare,

Volume of the large box = 4 x 3 x 5 = 60 ft³

Volume of a cube = 1 ft³

Total number of cubes = 1 x 65 = 65 ft³

Since, both the volumes are equal,

Therefore,

He cannot fit 65 smaller cubes into the large box, as he will be left with 5 boxes out of the box.

Hence, Diego can not put 65 boxes in the larger one.
