Answer:

0.32 I believe.

Step-by-step explanation:

If [tex]p[/tex] and [tex]q[/tex] are directly proportional, then they must have a common scalar.

To find [tex]q[/tex] we must first find its scalar. If we let [tex]a[/tex] be the scalar we can form the equation, [tex]ap = q[/tex].

We are given the information that if [tex]q = 7.5[/tex] then [tex]p = 9[/tex]. We can use that in finding the scalar.

[tex]a \times 9 = 7.5 \\ \frac{a \times 9}{9} = \frac{7.5}{9} \\ a = \frac{75}{90} \\ a = \frac{15}{18}[/tex]

Now we can solve for [tex]q[/tex] when [tex]p = 24[/tex] knowing that our scalar is [tex]\frac{15}{18}\\[/tex].

[tex]ap = q \\ \frac{15}{18} \times 24 = q \\ \frac{360}{18} = q \\ 20 = q[/tex]

[tex]q = 20[/tex] when [tex]p = 24[/tex]

Answer:

Closer to 0 than 0.5, or under zero

Step-by-step explanation:

On a vertical number line, anything above zero is positive, and anything under zero is negative. If 0.5 is the greater number, then it has to be closer to zero, or under it.

Answer:

The other number would be located below 0.5 on the vertical number line.

Answer:

D) [tex]1\frac{21}{40}m^2[/tex]

Step-by-step explanation:

We can first change the area of his garden into an improper fraction:

[tex]7\frac{5}{8} m^2 = \frac{61}{8}m^2[/tex]

Since Eric wants to split his garden into five equal sections, we divide the area of his garden by [tex]5[/tex]:

[tex]\frac{61}{8}\div 5 = \frac{61}{40}[/tex]

[tex]=1\frac{21}{40}m^2[/tex]

∴ The area of each new section is [tex]1\frac{21}{40}m^2[/tex]

Answer:x<-7/3

Step-by-step explanation:

Answer: X > -7/3

Step-by-step explanation:

-3x + 8 < 15

subtract 8 from both sides

-3x < 7

divide by negative 3

Also, when dividing or multiplying by a negative you flip the sign.

x > -7/3

Answer :)

So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. For each power of ten, you move one place to the left. So if you divided a number by one hundred (10^2 or 10*10), you would move two places to the left.

Answer:

D. [tex] y = \frac{2}{3}x - 2 [/tex]

Step-by-step explanation:

To find the equation of the line that is perpendicular to the one shown on the graph, which passes through (-3, -4) we need to find the slope of the line, m, and the y-intercept, b.

The equation would be in the slope-intercept form given as y = mx + b.

The slope of the line would be the negative reciprocal of the slope of the line shown on the graph.

So, first, find the slope of the line shown in the graph using the points on the line, (0, 3) and (4, -3):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 3}{4 - 0} = \frac{-6}{4} = -\frac{3}{2} [/tex]

Since the slope of the line shown on the graph is -³/2, therefore the slope of the line that is perpendicular to the line shown would be the negative reciprocal of -³/2. Negative reciprocal of -³/2 is ⅔.

Therefore, the slope, m, of the line that is perpendicular to the line shown is ⅔.

Let's find its y-intercept using the point given, (-3, -4) that the line passes through and its slope, m = ⅔.

Substitute m = ⅔, x = -3 and y = -4 in y = mx + b, to find b.

-4 = ⅔(-3) + b

-4 = -2 + b

Add 2 to both side

-4 + 2 = b

-2 = b

b = -2

Substitute m = ⅔, and b = -2 in y = mx + b.

The equation of the line would be:

[tex] y = \frac{2}{3}x +(-2) [/tex]

[tex] y = \frac{2}{3}x - 2 [/tex]

Answer:

133.33333333 percent

the diffrence is 800

Step-by-step explanation:

[(1400 - 600) / 600] × 100%

= 1.3333333333 × 100%

= 133.33333333%

Answer:

133.33% increase

Step-by-step explanation:

This is a percent increase, and to solve for one you need to know the following formula

[tex]|\frac{new~value~-~original~value}{original~value}| *100[/tex]

Plugging it in;

New value = 1400

Old value = 600

[tex]|\frac{new~value~-~original~value}{original~value}|= |\frac{1400-600}{600}| = |\frac{800}{600}| = 1.333333333[/tex]

1.3333333 as a percent is

133.33%

So you have an increase of 133.33%

Step-by-step explanation:

Properties of Exponents

The property called Power to a Power shows us how to simplify expressions of the type:

[tex](x^n)^m=x^{n*m}[/tex]

Similarily the property called Power of a product simplifies expressions like:

[tex](x.y)^n=x^n.y^n[/tex]

The company mentioned in the question uses the expression

[tex](2x^3)^3[/tex]

millimeters per second to calculate the maximum capacity of a photocell with an area of x^3 square millimeters.

First, use the power of a product property:

[tex](2x^3)^3=2^3\cdot (x^3)^3[/tex]

Now use the power to a power property:

[tex](2x^3)^3=2^3\cdot x^{3*3}[/tex]

Operate:

[tex]\mathbf{(2x^3)^3=8\cdot x^{9}}[/tex]

Answer:

3/8 shortening, 1/4 t salt, 9/8 sugar, 3/4 baking soda, 1/8 eggs, 1 c. Cake flour, 1/4, vanilla extract, 1/8 butter flavoring

Step-by-step explanation:

Half all your fractions, by doubling the numerator and denominator, then deviding the numerator by 2.

The amount require for 1 and half dozens is

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Let's first list the data that we currently have. The number of ice creams is 5. It costs $125 for 5 ice creams.

Step1 :Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

Shortbread Cookies Makes =3 dozen cookies

3/4 shortening

1/2 t salt

9/4 granulated sugar

3/2 t baking soda

1/4 eggs

2 c. cake flour

1/2 vanilla extract food coloring

1/4 butter flavoring

Above we have ingredients according to 3 dozen but we want to have ingredients for 1 and half dozen which is half of 3 dozen

So, we will just make half of the amount of above ingredients present

Shortbread Cookies Makes =1 and 1/2 dozen cookies

3/4 x 1/2 = 3/8 shortening

1/2 x 1/2 = 1/4 t salt

9/4 x 1/2 = 9/8granulated sugar

3/2 x 1/2 = 3/4t baking soda

1/4 x 1/2 = 1/8 eggs

2 x 1/2 =1 c. cake flour

1/2 x 1/2 = 1/4 vanilla extract food coloring

1/4 x 1/2 = 1/8 butter flavoring

Answer:

5/6x+4 1/6=y

Step-by-step explanation:

The equation to find a slope-intercept is mx+b=y

m=slope

x=x coordinates

y=y coordinates

b= y intercept

m=5/6

x=-1

y=-5

b=4 1/6

Y intercept:

5/6(-1)+b=-5

-5/6+b=-5

b=4 1/6

However, it asks for an equation of the line, not (-1,-5), so we only need to write m and b, but not x and y.

So: 5/6x+4 1/6=y
