Answer 1

Answer:

C

Step-by-step explanation:

When multiplying scalars and matrices, just distribute the scalar to every component of the matrix. So 4*6=24, -2*6= -12, 6*6 = 36, 7*6 = 42, 3*6 = 18, and 0*6 = 0.

Would someone please help me? Ravi decides to eliminate just 100 calories per day from his diet. He knows that each pound of body fat equals 3500 calories. How long will it take for Ravi to lose 10 pounds?

Answers

Answer:

350 days

Step-by-step explanation:

If Ravi is eliminating 100 calories per day, and one pound of body fat is 3500 calories, then it will take him 35 days to lose one pound of body fat.

Multiply 35 by 10 to find how long it will take for him to lose 10 pounds:

35(10)

= 350

So, it will take him 350 days to lose 10 pounds.

Answer:

350

Mohan is standing at a distance of 4 units from the origin in the negative direction of the x- axis. His friend Sohan is standing at a distance of 7 units from the origin in the negative direction of the y- axis. Find the distance between them

Answers

Answer:

8.06 units

Step-by-step explanation:

To obtain the distance, find the hypotenus using Pythagoras rule :

Hypotenus² = opposite² + adjacent²

Hypotenus² = 4² + 7²

Hypotenus² = 16 + 49

Hypotenus² = 65

Hypotenus = √65

Hypotenus = 8.06

Hypotenus = distance between the two points = 8.06 units

According to the line plot, what is the total amount of time spent studying by the students who studied for an hour each?

Answers

Answer:

2.5 hours

Step-by-step explanation:

The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.

Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.

Total amount of hours spent = 1/2 * 5 = 2.5 hours

Answers

Answer:

It is The median, because there is an outlier that is significantly higher than the rest of the data, and it raises the mean above the center of the data, making the mean a poor choice, and the median a better choice

Step-by-step explanation:

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches? StartRoot 2 EndRoot in. 2 StartRoot 2 EndRoot in. 4 StartRoot 2 EndRoot in. 36 StartRoot 2 EndRoot in.

Answers

Answer:

2.83 inches

Step-by-step explanation:

The formula for surface area of cube = 6s²

Where

s = side length of cube

S.A = 6s²

s² = S.A/6

s = √S.A /6

For cube a

Surface area = 1200 in²

Hence,

side length = √1200/6

Side length = √200

= 14.14 inches

For cube b

Surface area = 768 in²

Hence,

side length = √768/6

Side length = √128

= 11.13 inches

How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches?

Therefore,

14.14 inches - 11.13 inches

= 2.83 inches

Geometric : a7=9 and a12=2187

Answers

Step-by-step explanation:

a geometric sequence is s sequence, where every new element is generated by multiplying the previous element by the same number.

a n = a1 × number^(n-1)

so, a12/a7 = number^5

=> 2187/9 = 243 = number^5

=>

[tex]number = \sqrt[5]{243} [/tex]

=> number = 3

so, what is a1 ?

it has to satisfy e.g. a7.

9 = a1 × 3^6

9 = 3^2

=> 3^2 = a1 × 3^6

=> 1 = a1 × 3^4

=> a1 = 1/(3^4) = 1/81

therefore, the whole formula is

a n = 1/81 × 3^(n-1 )

What is 67,795 rounded to the nearest thousand?​

Answers

Answer: 68,000

Explanation

Answer:

68 000

Step-by-step explanation:

When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.

Answers

Answer:

C.)   8.68686 × [tex]10^{7}[/tex]

D.)   4.1688 × [tex]10^{2}[/tex]

Step-by-step explanation:

For C.)  you take 8.69 and multiply that by [tex]10^{7}[/tex] and you'll get 86900000

Then you take 3.14 and multiply that by [tex]10^{4}[/tex] and you'll get 31400

So then you take 86900000 and 31400 and subtract it...

86900000 - 31400 = 86868600 and you convert 86868600 to scientific Notation.

Which would equal **** 8.68686 × [tex]10^{7}[/tex] *****

For D.) you take 4.32 and multiply that by [tex]10^{3}[/tex] and You'll get 4320

then you take 9.65 and multiply that by [tex]10^{-2}[/tex] and you'll get 0.0965

So then you take 4320 and 0.0965 and subtract it...

4320 - 0.0965 = 4319.9035 and you convert 4319.9035 to Scientific Notation.

Which would equal **** 4.1688 × [tex]10^{2}[/tex] ****

First, we need to find 1/8 of 176, which is basically 176/8 = 22.

22 = 1/8

154 = 7/8

So 154 customers left satisfied and 22 unsatisfied.

3y = 4x + 12 ( divide the terms by 3 )

y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope- intercept form

with slope m = [tex]\frac{4}{3}[/tex] and y- intercept c = 4
