Answer 1

Answer:

Only Option 'A' and 'B' are correct.

a) Leena consumed 1,500 calories at dinner.

b) The equation 2/3(x + 400 + 350) = x can be used to model the situation.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, we have given that

Number of calories she consumed at breakfast = 400

Number of calories she consumed at lunch = 350

Now, Let number of calories she consumed at dinner be x

According to question,

She consumes 2/3 of her daily calories at dinner,

So, it becomes,

1/3 x total = 400 + 350

total = 2250

so, Number of calories she consumed at dinner is given by

2/3 of total = x

2/3 x 2250 = x

x = 1500

And by option 'B' we get,

2/3 (x + 400 + 350) = x

2 (x + 750) = 3x

2x + 1500 = 3x

x = 1500

So, only Option 'A' and 'B' are correct.

abbie spent 5/8 of her money and saved the rest. if she spent 45,how much money did she have at first?

Answers

$72

Further explanation

Given:

Abbie spent ⁵/₈ of her money and saved the rest.

She spent $45.

Question:

How much money did she have at first?

The Process:

The meaning of "Abbie spent ⁵/₈ of her money" is that she has spent 5 of the 8 parts of the money she had at first.

Let us make a pattern of 8 units for the amount of money that Abbie had at first.

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$

Since Abbie spent ⁵/₈ of her money, then we create a pattern of 5 units containing $9 each. Recall that $\boxed{\$ 45 / 5 = \$ 9}$

$\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9} = \$ 45$

From the pattern above, we can see that $\boxed{ \ 1 \ unit = \$ 9 \ }.$

Let us calculate how much money Abbie had at first.

$\boxed{ \ 1 \ unit = \$ 9 \ }$

$\boxed{ \ 8 \ unit = \ ? \ }$

$\boxed{ \ 8 * \$ 9 = \$ 72 \ }$

Thus, the money Abbie had at first is $72.

The complete pattern of Abbie's initial money is as follows:

$\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9}\boxed{\$ 9} = \$ 72$

- - - - - - - - - -

Quick Steps:

Let M as Abbie's initial money.

$\boxed{ \ (5)/(8) * M = \$ 45 \ }$

Both sides are multiplied by ⁸/₅ so that M is the subject alone on the left side.

$\boxed{ \ M = (8)/(5) * \$ 45 \ }$

We crossed out 5 and 45.

$\boxed{ \ M = 8 * \$ 9 \ }$

$\boxed{ \ M = \$ 72 \ }$

Thus, the money Abbie had at first is $72.

a cereal box is 8 1/2 inches long, 3 1/2 inches wide, and 12 inches high. what is the volume of the the box?

Answers

Length of the cereal box = 8 1/2 inches
= 17/2 inches
Width of the cereal box = 3 1/2 inches
= 7/2 inches
Height of the cereal box = 12 inches
Then
Volume of the cereal box = Length * Width * Height
= (17/2) * (7/2) * 12 cubic inches
= 17 * 7 * 12 cubic inches
= 1428 cubic inches

I think its 357 squared. Just multiply all of it together. I'd check the formula for finding volume if you want a reliable answer

Which expression is equivalent to (st)(6)?O s(t(6))
O s(x) × t(6)
Os(6) × t(6)
O 6 × S(x) × t(x)

Answers

Hello!

Answer:

$\large \boxed{\sf {\circ} ~~~s(t(6))}$

Step-by-step explanation:

→ We want an expression wich is equivalent with (st)(6).

→ Let's develop this expression:

$\sf (st)(6)\n\n= \ (st) * 6\n\n= 6st\n\n= 6 * s * t\n\n= s * 6t\n\n= s(6t)\n\n= s(6 * t)\n\n= s((t(6))$

Conclusion:

So an equivalent expression of (st)(6) is s((t)(6)).

Final answer:

The term (st)(6) in mathematics signifies that 's' and 't' are multiplied together, and the result is then multiplied by '6'. Using the associative property of multiplication, the equivalent expression is s(t(6)).

Explanation:

In mathematics, the expression (st)(6) signifies multiplication. The presence of parentheses indicates that the variables 's' and 't' should be multiplied together first, and then the product should be multiplied by '6'. This principle is known as the associative property of multiplication, which states that the way in which factors are grouped in a multiplication problem does not change the product. Therefore, the equivalent expression to (st)(6) is s(t(6)), which means 's' multiplied by the product of 't' and '6'.
