Answer:

A. Kaitlyn uses more cups of flour per cookie.

Step-by-step explanation:

Kaitlyn's

[tex]2\frac{1}{2}[/tex] cups of flour---> [tex]3\frac{1}{2}[/tex] cookies

1 cups of flour--> [tex]3\frac{1}{2}[/tex] / [tex]2\frac{1}{2}[/tex] = 1.4 cookies.

Megan's

[tex]1\frac{3}{4}[/tex] cups of flour---> [tex]2\frac{11}{12}[/tex]

1 cups of flour---> [tex]2\frac{11}{12} / 1\frac{3}{4}[/tex] = 1.67 cookies

Therefore, Kaitlyn uses more cups of flour per cookie.

The value of x is -2.2.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The linear equation 0.45x + 0.33 = -0.66

The value of x.

The linear equation 0.45x + 0.33 = -0.66 is given.

Then by simplification,

0.45x + 0.33 = -0.66

          0.45x = -0.66 - 0.33

          0.45x = -0.99

                  x = -2.2

Thus the value of x is -2.2.

False, The range for an exponential function does not include all real numbers but only real numbers greater than zero.

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given statement,

The range for an exponential function includes all real numbers.

By the definition,

Exponential functions have the general form y = f (x) = aˣ,

where a > 0, a≠1, and x is any real number.

The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1. Restricting a to positive values allows the function to have a domain of all real numbers.

Thus the range is all real numbers greater than zero.

Hence, The range for an exponential function includes all real numbers is False because it includes real numbers greater than zero.

Eighty 0ne ninths in 9 wholes

Answer:

D) x = -70

Step-by-step explanation:

You can do the opposite to find out what x equals. The opposite of division is multiplication. So, -7 · 10 = -70.

Check your answer by plugging in -70 for x. So -70/10 = -7. This is correct which means x = -70

Answer:

7.07 cm

Step-by-step explanation:

we know,

circumference = 2πr

so,

2 × 22/7 × r = 66

44r = 66×7 = 462

r = 462/44 = 1.5

therefore, radius of the circle is 1.5 cm.

now,

we know , area = πr²

so,

22/7 × (1.5)²

22/7 × 2.25

49.5/7

7.07 cm (approx)

therefore, area of the circle is 7.07 cm (approx.)

Answer:

x=1 or x=16

Step-by-step explanation:

3/4x = 12      or        0.75x = 12

3/4x/3/4 = 12/3/4     or     0.75x/0.75 = 12/0.75

x=12/1 / 3/4

x= 4/4

x = 1                           or       x = 16

Answer:

4

Step-by-step explanation:

Each box is 1 larger than the earlier one, so the boxes are 1, 2, 3, 4, and 5.

4 + 5 is the width across the bottom

2 + 3 is the width across the top (not counting h)

9 - 5 = 4, so h = 4

The value of h is 4. Hence, Option C is the best choice.

Found using the area of the given square.

The area of a square is the square of its sides.

If a represents the side of the square, then its area is a².

In the question, we are given five squares positioned as shown in the figure. The smallest square has an area of 1.

We are asked to find the value of h.

Now, the square of area 1, will have sides of length √1 = 1.

The second square, just greater than this, is nearly 1.5 times this square.

Hence the side of that square = 1.5*1 = 1.

The third square has a side equal to the sum of the side of these two squares. Hence, its side = 1 + 1.5 = 2.5.

The fourth square has a side equal to the sum of the third and the first square. Hence, its side = 2.5 + 1 = 3.5.

The fifth square has a side equal to the sum of the fourth and the first square. Hence, its side = 3.5 + 1 = 4.5.

Now, h = length of the fifth square - (length of the second square - length of the first square),

or, h = 4.5 - (1.5 - 1) = 4.5 - 0.5 = 4.

Hence, the value of h is 4. Hence, Option C is the best choice.

Answer:

D. x = 8

Explanation:

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

[tex]\frac{3x}{30}[/tex] = [tex]\frac{48}{30+30}[/tex]

[tex]\frac{3x}{30}[/tex] = [tex]\frac{48}{60}[/tex]

3x * 60 = 48 * 30

180x = 1440

x = 1440 ÷ 180

x = 8

Triangle ACD is an enlarged triangle of Triangle ABE

so an equation can be formed to solve this:

[tex]\frac{3x}{30} = \frac{48}{30 + 30} [/tex]

[tex] \frac{3x}{30} = \frac{48}{60} [/tex]

[tex] \frac{3x}{60} = \frac{48}{30} [/tex]

[tex]180x = 1440[/tex]

[tex]x = \frac{1440}{180} [/tex]

[tex]x = 8[/tex]

Elena made 10 batches.

Step-by-step explanation:

1 batch uses 2/3 cup

Elena used 6 2/3 cup

The number of batches is the quotient of 6 2/3 and 2/3.

We need to divide 6 2/3 by 2/3. First, we convert 6 2/3 into a fraction.

6 2/3 ÷ 2/3 = 20/3 ÷ 2/3 = 20/3 × 3/2 = 10
