Sam hss 100 cheese slices to make sandwiches. The equation below can be used to find s, the number of sandwiches he can make based on c, the number of cheese slices per sandwich.

s=100/c
Which equation is the same when solved for c in terms of s?

F. C=100/c
G. C=s/100
H. C=100-s
J. C= s-100

Answer:

A and D

Step-by-step explanation:

Given that the area of a square = 400 units² = s²

Where s is one side length of the square.

It means that the side length (s) = √400 = 20

If the length of each side length increase by 1 units, new side length = 21 units

Area of new square = 21² = 441

The following statements would be true if the side length was increased by 1 units:

A. "The area of the square would be a rational number"

441 is a rational number, because a rational number is a quotient of two integers.

441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441

D. "The area of the square would be a perfect square".

A number is considered a perfect square if it can be expressed as a product of two equal integers.

441 can be expressed as 21*21

Answer:

[tex]f(-3)=24[/tex]

Step-by-step explanation:

So we have the function:

[tex]f(x)=|4x-2|+10[/tex]

To find f(-3), substitute -3 for x:

[tex]f(-3)=|4(-3)-2|+10[/tex]

Multiply within the absolute value:

[tex]f(-3)=|-12-2|+10[/tex]

Subtract:

[tex]f(-3)=|-14|+10[/tex]

The absolute value of -14 is 14. Thus:

[tex]f(-3)=14+10[/tex]

Add:

[tex]f(-3)=24[/tex]

Formula used to calculate the volume of square pyramid is:

[tex]V=\frac{a^2\times h}{3}[/tex]

where,

V = volume of pyramid

a = base edge of pyramid

Answer:

Length = 12.75 feet

Width= 2.25 feet

Step-by-step explanation:

Let the length = x

Let the width= y

The length of a rectangular classroom floor is 6 feet more than twice the width

X= 6+2y

The perimeter is 30 feet.

Perimeter= 2(length+width)

Perimeter= 2(x+y)

30= 2x +2y

But x= 6+2y

30 = 2(6+2y) +2y

30= 12 +4y +4y

30-12= 8y

18= 8y

2.25 = y

30= 2x +2y

30= 2x +2(2.25)

30- 4.5= 2x

25.5= 2x

12.75= x

Length = 12.75 feet

The value after simplifying the expression 3² + 8 ÷ 2 - (4 + 3) is 6 by using PEMDAS rule.

To simplify the expression 3² + 8 ÷ 2 - (4 + 3), follow the order of operations (PEMDAS/BODMAS):

P - Parentheses first

E - Exponents (i.e., powers and square roots, etc.)

MD - Multiplication and Division (left to right)

AS - Addition and Subtraction (left to right)

Start with the exponent:

3² = 3 × 3 = 9.

Next, perform the division:

8 ÷ 2 = 4.

Now, deal with the parentheses:

(4 + 3) = 7.

Finally, perform the addition and subtraction from left to right:

9 + 4 - 7

= 6.

So, the simplified expression is 6.

Answer:

d. x = 5

Step-by-step explanation:

Solve for x:

x - 3 = 7 - x

Hint: | Move terms with x to the left hand side.

Add x to both sides:

x + x - 3 = (x - x) + 7

Hint: | Look for the difference of two identical terms.

x - x = 0:

x + x - 3 = 7

Hint: | Add like terms in x + x - 3.

x + x = 2 x:

2 x - 3 = 7

Hint: | Isolate terms with x to the left hand side.

Add 3 to both sides:

2 x + (3 - 3) = 3 + 7

Hint: | Look for the difference of two identical terms.

3 - 3 = 0:

2 x = 7 + 3

Hint: | Evaluate 7 + 3.

7 + 3 = 10:

2 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 2 x = 10 by 2:

(2 x)/2 = 10/2

Hint: | Any nonzero number divided by itself is one.

2/2 = 1:

x = 10/2

Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

The required rule describes the rotation about the origin is given as (-x, -y). And the measure of rotation is 180°.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,

The coordinate of the given point is (1, 1), and after rotation coordinates are (-1, -1) about the origin. It shifted from 1st quadrat to the 3rd quadrant. It implies,

The point rotated with an angle of 180° so that its coordinates were translated by formula,

Answer:

15 ounce bag is cheaper per ounce than 9.75 ounce bag.

Step-by-step explanation:

For this problem, you should simply take the cost divide by the size for each to find the price per ounce.

$3.98 / 15oz == $0.265 per ounce

$2.98 / 9.75oz == $0.306 per ounce

Note that the 15 oz bag is a better price per ounce than the 9.75 oz bag.

As to what bag you should buy, that really should depend on more factors than just what's best per ounce.  For instance, are you really hungry enough for 15 ounces of doritos, or will 9.75 do just fine?  Also, do you even have the extra dollar it would cost to buy the bigger bag?  Just some stuff to think about.
