For her science project, jada wants to build a rectangular prism out of foam block. The block should have a volume of 350 in.³ and a height of 5 inches. Part A What tool can help Jada find possible dimensions for the base of the block Explain. Part B Give one pair of possible whole number dimensions for the base

Answers

Answer:

10 in * 7in

Step-by-step explanation:

Given that :

Volume of block = 350 in³

Height of block = 5 inches

The dimension of block can be expressed cubic units

Volume of a rectangular prism :

V = length * width * height

Let ; length * width = B

350 = B * 5

B = 350 / 5

B = 70 in²

Possible dimension of B:

B = length *width

70 in² = 10 in * 7in

Hence, possible whole number dimension for the base = 10 in * 7in

the perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area​

Answers

Answer:

63 cm^2

Step-by-step explanation:

p = l + w + l + w

32 = 2l + 2w

32 = 2(w + 2) + 2w

32 = 2w + 4 + 2w

32 = 4w + 4

28 = 4w

7 = w

l = w + 2

l = 7 + 2

l = 9

Check your work:

32 = 9 + 7 + 9 + 7

32 = 32

Correct

A = l × w

A = 9 × 7

A = 63

A 1200 kg car and a 2400 kg car are lifted to the same height at a constant speed in a auto service station. Lifting the more massive car requires ____ work.

Answers

to be honest with you, I dont know

The work required to lift the massive car of 2400 kg is more than lifting the car with 120 kg

What is Work?

Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is defined as the product of the force's magnitude and the distance traveled. The dimensions of work is

ML²T⁻² and the SI unit of work is Joule

Work = Force x Distance

The SI unit for work is the joule (J), or newton meter ( Nm ). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m

Given data ,

Let the work required to move the 2400kg car be W₁

Let the work required to move the 1200kg car be W₂

Now , the force in moving the 2400 kg car = F₁

The value of F₁ = 2400 ( a )

And , the force in moving the 1200 kg car = F₂

The value of F₂ = 1200 ( a )

where a is the acceleration

Let the distance moved be height H

Now , the work W₁ = Force x Distance

Substituting the values in the equation , we get

W₁ = 2400 ( a ) H

And , W₂ = 1200 ( a ) H

Now , W₁ > W₂

Hence , the work required to move 2400 kg car is greater

Find Thin Mints in radians

Need help with math homework

Answers

Answer:

a) Thin mints = 1.885 radians

b) Savannah smiles cookies = 0.332 radians

Step-by-step explanation:

To convert an angle from degree to radians, the formula is given as :

x ° × π/180 = radians

Where x = angle to be converted

From the diagram we are to convert Thin mints and Savannah cookies to radians

a) Thin mints = 108°

Converting to radians

= 108° × π/180

= 1.8849555922 radians

Approximately = 1.885 radians

b) Savannah smiles cookies = 19°

Converting to radians

= 19° × π/180

= 0.331613 radians

Approximately = 0.332 radians

A number x, rounded to 2 decimal places is 7.42 write down the error interval for x

Answers

Answer:

7.415 ≤ x < 7.425

Step-by-step explanation:

The number x was rounded to 2 decimal places to give 7.42.

Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.

Thus;

7.42 ± (0.01/2)

(7.42 - 0.005),(7.42 + 0.005)

7.415, 7.425

Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.

Thus,the error interval is;

7.415 ≤ x < 7.425

find the product of 10.2 and 6.3​

Answers

Answer:

10.2*6.3=64.26

Step-by-step explanation:

Solve 102*63, then move the decimal point two numbers from the right:

Since 102*63=6426, then moving the decimal point two numbers from the right will mean 10.2*6.3=64.26

Answer:

64.26

Step-by-step explanation:

This is a simple multiplication

When you 'multiply' or 'times' even a product of a number you add it to itself a number of times, for this problem, 10.2 multiplied by 6.3 is the same as saying 10.2 + 10.2 + 10.2 = 64.26. Multiplication is therefore a quicker way of adding the same number many times, for example, 10.2 × 6.3 = 64.26. Therefore, the product of 10.2 and 6.3​ is 64.26.

Answers

Answer:

what are the answer choices

Step-by-step explanation:

The linear expression 24y - 12 is not equivalent to the expression 2(12y - 12) option (A) 2(12y - 12) is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a linear expression:

= 24y - 12

From the above linear expression take 2 as a common factor:

= 2(12y - 6)

Take 2 as common factor again:

= 2(2)(6y - 3)

= 4(6y - 3)

Now, take 3 as a common factors:

= 12(2y - 1)

The expression 24y - 12 is equivalent to the expressions 2(12y - 6), 4(6y - 3), and 12(2y - 1).

Thus, the linear expression 24y - 12 is not equivalent to the expression 2(12y - 12) option (A) 2(12y - 12) is correct.
