Hailey divided 92 ÷ 5. Her work is shown below.


92 divided by 5. 5 goes into 9 1 time. 9 minus 5 = 4. 5 goes into 42 8 times. 42 minus 40 = 2. The answer is 18 R 2. There are 5 groups of 1 ten plus 8 ones.
Which statements are true about Hailey’s work? Check all that apply.

Hailey found the correct quotient.
The “1” in the quotient represents the number of tens in each of the 5 groups.
Hailey placed the dividend and divisor in the wrong places in the problem.
The “R2” represents the number of ones in each of the 5 groups.
Since only 5 tens could be divided evenly among the groups, Hailey subtracted 5 from 9 to find out how many tens were left over.

Answer:

EM = 42

Step-by-step explanation:

If M is the midpoint, then we can say that EM = MG.

So now, I can set up an equation:

7x = 8x - 6

And solve for x.

7x = 8x - 6

 -8x     -8x

-x = -6

x = 6

Since we are trying to find EM, and EM is 7x, we can multiply x by 7 to find our answer:

7x

7(6)

42

EM = 42

Step-by-step explanation:

15 : 40

Both have table of 5 in common

5 : 8

You divide it with valid numbers that can be dividable with both numerator and denominator.

15/40 can be divided by 5 to make it into the simplest form

= 3/8 , now we can no longer divide it, so its the simplest form

Answer:

(12, 10 )

Step-by-step explanation:

Given the endpoints of a segment (x₁, y₁ ) and (x₂, y₂ ) then midpoint is

[ [tex]\frac{1}{2}[/tex](x₁ + x₂ ), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]

let (x, y) be the coordinates of the other endpoint then use the midpoint formula and equate to the coordinates of the midpoint.

(x₁, y₁ ) = (- 2,  6) and (x₂, y₂ ) = (x, y), then

[tex]\frac{1}{2}[/tex](- 2 + x) = 5 ( multiply both sides by 2 )

- 2 + x = 10 ( add 2 to both sides )

x = 12

[tex]\frac{1}{2}[/tex](6 + y) = 8 ( multiply both sides by 2 )

6 + y = 16 ( subtract 6 from both sides )

y = 10

Thus

The other endpoint is (12, 10 )

Answer:

(12, 10 )

Step-by-step explanation:

Given the endpoints of a segment (x₁, y₁ ) and (x₂, y₂ ) then midpoint is

[ (x₁ + x₂ ), (y₁ + y₂ ) ]

let (x, y) be the coordinates of the other endpoint then use the midpoint formula and equate to the coordinates of the midpoint.

(x₁, y₁ ) = (- 2, 6) and (x₂, y₂ ) = (x, y), then

(- 2 + x) = 5 ( multiply both sides by 2 )

- 2 + x = 10 ( add 2 to both sides )

x = 12

(6 + y) = 8 ( multiply both sides by 2 )

6 + y = 16 ( subtract 6 from both sides )

y = 10

Thus

The other endpoint is (12 ,10)

Answer:

46.7 degrees.

Step-by-step explanation:

According to the given information, triangle DEF is a right triangle with angle F as the right angle. We are trying to find the measure of angle D.

We are given the opposite side length (6.4 feet) and the hypotenuse (8.8 feet), so we can use sine to calculate the angle measure (SOH = Sine; Opposite over Hypotenuse).

sin(D) = 6.4 / 8.8

sin(D) = 64 / 88

sin(D) = 8 / 11

D = arcsin(8 / 11)

D = arcsin(0.72727272727272727272727273)

D = 46.65824177.

So, the measure of angle D is about 46.7 degrees.

Hope this helps!

Answer:

so the order will be 5 x 2

Step-by-step explanation:

When we find the transpose of a matrix we change the rows into columns and columns into rows so the order is also reversed.

The order of  B transpose will be reversed i.e. it will 5 x 4.

When we multiply two matrices we check the columns of the first matrix should be equal to the rows of the second matrix and the answer should contain the rows of the first matrix and the columns of the second matrix as the order of the resultant matrix

B^T (5 X 4)  X D ( 4 X 2)

B^TD (5 X 2)

Now ED will be

E (5 x 4) D (4 x 2)

ED ( 5 x 2)

Now adding

B^TD (5 X 2) + ED ( 5 x 2) = (B^T × D) + ED ( 5 x 2)

In addition the order does not change.

Answer:

The square root property requires a quantity squared by itself on one side of the equation. the only quantity squared is x, so divide both sides by 2 before applying the square root property.  

Step-by-step explanation:

To solve the given equation of 2x^2=16, the first step is to divide both sides by two to isolate the variable x. This leaves you with x^2=16. the next step would be to use the square root property, leaving the equation as x= 16 squared. then solve for x by squaring 16. This leaves it as x= 4 or -4

Answer:

They are perpendicular lines

Step-by-step explanation:

If one line has slope -8 and the other one has slope 1/8, they must be perpendicular to each other because the condition for perpendicular lines is that the slope of one must be the "opposite of the reciprocal of the slope of the original line."

the opposite of -8 is 8 , and the reciprocal of this is 1/8

Answer:

Below

Step-by-step explanation:

Let m and m' be the slopes of two different lines.

These lines are peependicular if and only if:

● m×m' = -1

Notice that:

● -8 ×(1/8) = -1

So the lines with the respectives slopes -8 and 1/8 are perpendicular.

Answer:

[tex]\mathrm{Center\:\:}= (- 3,17)\\\mathrm{Radius\:\:}= 13[/tex]

Step-by-step explanation:

Remember that the center of the circle would be equidistant from the given points that lie on the circle.

By determining the diameter through the distance of the given points, we can determine the radius by dividing this distance by 2. And by determining the radius we can determine the center of the circle. Let's do it.

[tex]\mathrm{Distance\:between\:}\left(2,\:5\right)\mathrm{\:and\:}\left(-8,\:29\right) = \sqrt{\left(-8-2\right)^2+\left(29-5\right)^2} = 26[/tex]

[tex]\mathrm{Radius\:\:}= 26 / 2 =13[/tex]

So now that we know the radius is 13 units, we can eliminate answer choice(s) # 2 and # 4. That leaves us with the first and third answer choices. The center being (5,12) is not likely, as most of the circle lies in the 2nd quadrant. That is presumably why (- 3,17) is more predictable. Our answer is the third option.

Answer:27

Step-by-step explanation:

The numerical length of IJ is 27 units.

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that Point, I is on line segment HJ. Given HI = x, IJ = 2x + 9, and

HJ = 4x.

The total length of the line will be written as below:-

HJ = HI + IJ

4x = x + 2x + 9

4x = 3x + 9

4x - 3x = 9

x = 9

The length of the segment IJ will be:-

IJ = 2x + 9

IJ = ( 2 x 9 ) + 9

IJ = 18 + 9

IJ = 27

Therefore, the numerical length of IJ is 27 units.

Answer:

x = 3

Step-by-step explanation:

7/x - 3/(2x) + 7/6 = 9/x

x(7/x  - 3/(2x)  + 7/6) = x(9x)

x*7/x  - 3*x/(2x) + x*7/6 = x*9x

7 - 3/2 + 7x/6 = 9

7x/6 = 9 - 7 + 3/2

7x/6 = 2 + 3/2

7x/6 = 12/6 + 9/6

7x = 12+9

7x = 21

x = 21/7

x = 3

probe:

7/3 - 3/(2*3) + 7/6 = 9/3

14/6 - 3/6 + 7/6 = 3

(14 - 3 + 7) / 6 = 3

Answer:

a. T = -1.72x + 212

b. 12,790 feet

Step-by-step explanation:

a. Let us assume the number of 1,000 elevation feet be x

Now the equation would be

T = -1.72x + 212

here the negative sign represents the fall in the boiling temperature with rise in elevation

b. Since the formula is

T = -1.72x + 212

can we write

T  - 212 = -1.72x

now divide by 1.72 in both the sides

[tex]\frac{t-212}{-1.72} = x\\\\ \frac{190-212}{-1.72} = x\\\\ \frac{-22}{-1.72} = x[/tex]

x = 12.79

So in feets it should be

Answer: The LCM of 3 and 8 is 24.

Step-by-step explanation:

So far, the given two numbers are 3 and 8. We have to find the LCM ( Least Common Multiple ) of 3 and 8, not the GCF ( Greatest Common Factor). That means, we have to find the smallest multiple of 3 and 8.

Let's try it out.

3 times 1 = 3. Is that a multiple of eight? No.

3 times 2 = 6. Is that a multiple of eight? No.

3 times 3 = 9. Is that a multiple of eight? No.

3 times 4 = 12. Is that a multiple of eight? No.

3 times 5 = 15. Is that a multiple of eight? No.

3 times 6 = 18. Is that a multiple of eight? No.

3 times 7 = 21. Is that a multiple of eight? No.

3 times 8 = 24. Is that a multiple of eight? YES!

Now try it out for 8.

8 times 1 = 8. Is that a multiple of three? No.

8 times 2 = 16. Is that a multiple of three? No.

8 times 3 = 24. Is that a multiple of three? YES!

So now that 24 occurs in the list for both of them, it is the LCM because there are no other numbers that come before it that are multiples of both 3 and 8.

The LCM of 3 and 8 is 24.

The LCM (Least Common Multiple) of two numbers is the smallest number that is a multiple of both numbers.

To find the LCM of 3 and 8, we can use the following steps:

1. List out the multiples of 3 until we reach a number that is divisible by 8.

2. List out the multiples of 8 until we reach a number that is divisible by 3.

3. The smallest number that appears in both lists is the LCM of 3 and 8.

The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27...

The multiples of 8 are 8, 16, 24, 32 ...

The smallest number that appears in both lists is 24. Therefore, the LCM of 3 and 8 is 24.

Answer:

x = 6

Step-by-step explanation:

11 = 1/2x + 8

-> Move 8 to left side

11 - 8 = 1/2x

3 = 1/2x

->We can switch sides so 1/2x is on the left and 3 is on the right

1/2x = 3

x = 3 x 2/1

x = 6

Answer:

x=6

Step-by-step explanation:

11=1/2x+8

subtract 8 from both sides first.

11-8=1/2x

3=1/2x

Now, multiply by 2 or divide by 1/2 from both sides (your pick)

3*2=x

Therefore the answer is x=6

Formula :-

Volume of cylinder is π r²h .

Given :-

→ Volume = 308 cm³

→ Radius = 7 cm

Solution :-

→ πr²h = 308

→ π (7)²(h) = 308

→ 22×7×7×h/7 = 308

→ 22×7×h = 308

→ 154×h = 308

→ Height = 308/154

→ Height = 2 cm

So the height of the cylinder is 2 cm .
