so it's going to be

128=64/3X

so X is 128 ÷ 64/3=6cm

Answer:

I'm Sure the answer is 6 cm.

Answer: Option A.

Step-by-step explanation:

You need to remember the Quotient property of powers, which states the following:

[tex]\frac{p^m}{p^n}=p^{(m-n)}[/tex]

Then, given the expression [tex]\frac{a^3b^2}{a^2b}[/tex], you need to apply this property to simplify this expression.

Therefore, you get:

[tex]=a^{(3-2)}b^{(2-1)}\\\\=a^1b^1\\\\=ab[/tex]

As you can observe, this matches with the option A.

A.Conjunction

Step-by-step explanation:

The area of the cross section that is parallel to side PQRS in this rectangular box is: A. 12 square units.

In Mathematics and Geometry, the area of a rectangle can be calculated by using the following mathematical equation:

A = LW

Where:

A represent the area of a rectangle.

W represent the width of a rectangle.

L represent the length of a rectangle.

By substituting the given side lengths into the formula for the area of a rectangle (PQRS), we have the following;

Area of rectangle = PQ × QR

Area of rectangle = 4 × 3

Area of rectangle = 12 square units.

Complete Question:

What is the area of the cross section that is parallel to side PQRS in this rectangular box?

A. 12 square units

B. 16 square units C. 30 square units D. 40 square units

The volume of the rectangular box is 60 cubic units.

Given that the area of one side of the box is 12 and the area of another side is 15, and both dimensions are integers greater than 1, we can find the dimensions and the volume of the box as follows:

Possible dimensions:

For the side with area 12, the possible integer dimensions are (3, 4) and (4, 3) since 3 x 4 = 4 x 3 = 12.

For the side with area 15, the possible integer dimensions are (3, 5) and (5, 3) since 3 x 5 = 5 x 3 = 15.

Valid dimensions combination:

We need to find a combination of dimensions where the two sides mentioned above are not the same.

The only valid combination is (3, 4) for the side with area 12 and (5, 3) for the side with area 15.

Volume of the box:

The volume of the box is calculated by multiplying the length, width, and height.

In this case, the volume is 3 (length) x 4 (width) x 5 (height) = 60 cubic units.

Therefore, the volume of the rectangular box is 60 cubic units.

Question

The dimensions of a rectangular box are integers greater than 1. If the area of one side of this box is 12 and the area of another side 15, what is the volume of the box?

Answer:

2x + 11 = 20

Step-by-step explanation:

let's start by assigning the variable x to certain number , if we two times a certain number we got 2x, and if we added to 11 the result is 20. So, ordering the equation we will obtain:

2x + 11 = 20

ANSWER

2x+11=20

EXPLANATION

Let the number be x.

Two times this number is 2x

If 11 is added to two times the number, the expression becomes;

2x+11

If the result is 20, then we equate the expression to 20 to get:

2x+11=20

The correct choice is the last option;

Answer:

15-6+7=16. The expression should be written as 15-(6+7).

Step-by-step explanation:

The sum of 6 and 7 is (6+7). 15 minus the sum of 6 and 7 would then be written as 15-(6+7), because this way you subtract the entire sum from 15. The expression 15-6+7 just subtracts 6 from 15, then adds 7 onto this number, which is not the same thing as subtracting 6+7 from 15.

The expression 15 - 6 + 7 does not represent '15 minus the sum of 6 and 7'. The correct expression should be 15 - (6 + 7). Evaluating Harper's expression gives 16, while the correct expression gives 2.

The expression 15 - 6 + 7 does not properly relay the concept of '15 minus the sum of 6 and 7'. To correctly express this idea, parentheses should be used: 15 - (6 + 7).

To evaluate Harper's expression, one would operate in the order of their entry: 15 - 6 is 9, then, add 7 to 9 and the result is 16.

However, in the correct expression 15 - (6 + 7), the sum of 6 and 7 equals 13 is computed first, according to the order of operations (PEMDAS/BODMAS). Then, subtract this sum from 15 to get 2.

Answer:

The area is 154 cm²

Step-by-step explanation:

Since the formula for the area of a circle is pi times the radius squared, divide the diameter in half to get the radius (7). Then, square the radius (49). Next, multiply that by pi (153.938). After that round to the nearest whole number (154). Hope that helps!

-Kyra

Answer:

A = 154 cm^2

Step-by-step explanation:

We know the diameter of the circle

We need to find the radius

d = 2r

14 = 2r

Divide by 2

14/2 = 2r/2

7=r

Now we can use the formula for area

A = pi r^2

A = pi (7)^2

A = 49pi

Replace pi with 3.14

A = 49(3.14)

A = 153.83

Rounding to the nearest whole number

A = 154 cm^2

Answer:

37%

Step-by-step explanation:

35% of 55% is equal to the percent of boys on honor roll in the student body.

100 - 55 = 45%, which is the percent of girls in the student body.

40% of 45% is equal to the percent of girls on honor roll in the student body.

35% * 55% = 19.25%

40% * 45% = 18%

Adding them up, we get:

19.25 + 18 = 37.25%

Round it to the nearest percent.

37.25 --> 37%

Rounded to the nearest percent, 37% of the student body is on honor roll.

Answer:

-3.8, 3

Step-by-step explanation:

The solution to a system is where the graph cross each other.  If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite.  So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x.  To the right of the origin, where x is positive, the graphs cross where x = 3..

Answer:

  x = −3.8, 3

Step-by-step explanation:

The solutions to f(x) = g(x) are the x-coordinates of the points of intersection of their graphs. Those x-values appear to be about -3.8 and +3.

Answer:

0.66

Step-by-step explanation:

24.95 x 25%=6.23

24.94 - 6.23 = 18.72

25.80 x 30% = 7.74

25.80 - 7.74 = 18.06

18.72 -18 .06 = 0.66

For this case we have:

Store 1:

We propose the following rule of three:

24.95 -----------> 100%

x -------------------> 25%

Where the variable x represents the discount amount:

[tex]x = \frac {25 * 24.95} {100}\\x = 6.2375[/tex]

Thus, the price of the ball is:

[tex]24.95-6.2375 = 18.7125[/tex]

Store 2:

We propose the following rule of three:

x -------------------> 30%

Where the variable x represents the discount amount:

[tex]x = \frac {30 * 25.80} {100}\\x = 7.74[/tex]

Thus, the price of the ball is:

25.80-7.74 = 18.06

As Rhombus has four Congruent sides.2 Congruent sides does not Guarantee that the Parallelogram will be Rhombus.If Adjacent sides are congruent than Claire statement will be right otherwise not.

Statement of Jacob

If Jacob draws a parallelogram with at least 3 congruent sides ,it must be a rhombus.

Yes ,three congruent sides Guarantees that Parallelogram will be a rhombus because in a Parallelogram opposite sides are equal to each other.So congruency of three sides in a Parallelogram guarantees that this Parallelogram will be a rhombus.

So, we can Conclude that Jacob is correct.

  a.  12/37

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

  Sin = Opposite/Hypotenuse

  sin(A) = BC/AB = 12/37

The value of sin A in triangle ABC, where AB = 37 and BC = 12, is 12/37.

In a right-angled triangle, the sine of one of the non-right angles (A in this case) is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. The hypotenuse is the side opposite the right angle (side AB in this case).

To find the value of sin A in triangle ABC, we can use the formula:

sin A = BC / AB

Given that AB = 37 and BC = 12, we have:

sin A = 12 / 37

So, the correct answer is: a. 12/37

Step-by-step explanation:

Answer:

$135

Step-by-step explanation:

step 1

Let

x----> amount of money shared by Danny

y----> amount of money shared by Amira

z----> amount of money shared by Tyler

we know that

x/y=6/4 ----> x=1.5y ----> equation A

x/z=6/3 ---> z=x/2 ---> equation B

Amira used 1/2 of her money to buy a watch that costs $30

so

(1/2)y=$30

y=$60

Substitute the value of y in the equation A and solve for x

x=1.5y ----> x=1.5(60)=$90

Substitute the value of x in the equation B and solve for z

z=x/2 -----> z=90/2=$45

so

The amount of money shared by Danny was $90

The amount of money shared by Amira was $60

The amount of money shared by Tyler was $45

step 2

Find out how much money they have left in total.

Danny gave 1/3 of his money to his sister ----> left --> (2/3)($90)=$60

Amira used 1/2 of her money -----> left --> $60/2=$30

Tyler --------> left ----> $45

Total=$60+$30+$45=$135

Total left = Danny + Amira + Tyler = $60 + $30 + $45 = $135.

The question deals with dividing a sum of money among Danny, Amira, and Tyler by the ratio 6 : 4 : 3, calculating how much Amira spent, and how much Danny gave away.

Let's assume the total sum of money is M, shared according to the ratio 6x : 4x : 3x, which means:

Since Amira spent 1/2 of her money on a watch costing $30, we can deduce:

Therefore, the total sum of money M is 6x + 4x + 3x = 13x, which gives us:

Danny gave away 1/3 of his share to his sister, which is:

After spending and giving money away, they have left:

Total left = Danny + Amira + Tyler = $60 + $30 + $45 = $135.

[tex]\bf \cfrac{1}{2}\div 3\implies \cfrac{1}{2}\div \cfrac{3}{1}\implies \cfrac{1}{2}\cdot \cfrac{1}{3}\implies \cfrac{1}{6}[/tex]
