Answer:

Step-by-step explanation:

Say, in relation 3/4 gal of paint : 1/5 of wall. The decimal equivalent is 0.75 : 0.2. With this info., you can multiply 0.2 to get 1 which is equivalent to 1/5 X 5 to get 5/5. What you do to one side, you do to the other, so 0.75 X 5, which gives you 3.75 gal of paint. Round it to 4. So the final answer is 4 gal of paint.

3/4 : 1/5  ->  0.75 : 0.2  ->  5 x 0.75 : 0.2 x 5  ->  5 x 3/4 : 1/5 x 5

15/4 : 5/5  ->  3.75 : 1  = about 4 gals of paint b/c you can't just buy 3.75 gals of paint.

A transformation is a dramatic change in form or appearance. An important event like getting your driver's license, going to college, or getting married can cause a transformation in your life. A transformation is an extreme, radical change.

here, we have to,

to interpret the sequence of transformations,

The coordinates of the quadrilateral ABCD are;

A(-3, 4)

B(-7, -3)

C(-3, -7)

D(-4, -3)

Now, the first sequence of transformation is reflection across the y-axis. Now, the transformation rule for reflection across the y-axis is;

(x, y) → (−x, y) .

Thus, we now have;

A'(3, 4)

B'(7, -3)

C'(3, -7)

D'(4, -3)

It is now translated 9 units left and as such the transformation rule is;

((x + 9), y)

We now have;

A'(12, 4)

Answer:

This one is quite tough as I too was stuck on this one, I believe the answer is B. I hope this helps.

Answer:

x = 2

Step-by-step explanation:

We can start by rewriting the equation as follows:

100 * (1/5)^x / 4 = 4

Next, we'll multiply both sides by 4 to cancel out the division by 4:

400 * (1/5)^x = 16

Finally, we'll divide both sides by 400 * (1/5)^x to isolate (1/5)^x:

1/((1/5)^x) = 16 / 400 = 1/25

Taking the reciprocal of both sides:

(1/5)^x = 25

Taking the power of 5 to both sides:

x = log(25)/log(5) = 2

So x = 2 is the solution to the equation.

Step-by-step explanation:

See the attached attachment

Answer:

[tex]x^{2} - 14 = 50[/tex]

Step-by-step explanation:

Let x = Unknown number

Number squared = [tex]x^{2}[/tex]

Difference between the number squared and 14 is 50:

= [tex]x^{2} - 14 = 50[/tex]

= [tex]x^{2} = 14 + 50[/tex]

= [tex]x^{2} = 64[/tex]

(NOTE: It cannot be [tex]14 - x^{2} = 50[/tex] since:

[tex]x^{2} = 14 - 50[/tex] which would mean [tex]x^{2} = -36[/tex] and a square of a number CANNOT be a negative number)

Taking the square root of both sides to get rid of the square:

= [tex]x = \sqrt{64}[/tex]

= x = ±8

The area of shape B is 312.5 cm²

Let us assume that the area of the shape B is m square units.

Here, the dimensions of shape A is 12 cm and the area of the shape A is 200 cm²

The dimensions of shape B is 15 cm and the area of the shape B is m cm²

Since A and B are two similar 2D shapes their dimensions must be in proportion.

So, we get an equation,

⇒ A² / B² = 200 / m

⇒ 12² / 15² = 200 / m

⇒ 144 / 225 = 200 / m

⇒ m = (225/144) × 200

⇒ m = 312.5 cm²

Therefore, the area of shape B is 312.5 cm²

Area of the backyard is 9000 sq.ft. Area of the flower garden is 60 sq.ft. So the area of backyard planted with grass will be 8940 sq.ft.

Here the backyard is in rectangular shape and the flower garden is a parallelogram.

Backyard has a length  of 120ft and a width of 75ft. Area of a rectangle is given by the equation

Area of rectangle = length× width = 120×75 =9000 sq.ft

Area of backyard = 9000 sq.ft

The flower garden is a parallelogram with base 12 ft and height 5 ft.

Area of a parallelogram =  Base× height = 12×5 = 60 sq.ft

Area of flower garden = 60 sq.ft

All the remaining area is planted with grass. So, the area of the portion of backyard planted with grass = Total area of backyard- area of the flower garden.

Area planted with grass = 9000-60 = 8940 sq.ft

So the area of the backyard is 9000 sq.ft, area of the flower garden is 60 sq.ft and area planted with grass is 8940 sq.ft.

The answer is:

A frequency distribution for a collection of data is shown in the accompanying table.

The intervals or ranges of the data are displayed in the left column of the table, and the frequency or number of observations within each interval is displayed in the right column.

For instance, the first row demonstrates that 4 observations fall within the range of 10 to 19 while the second row demonstrates that 5 observations fall within the range of 20 to 29.

We only combine the frequencies to determine the total number of observations:

Total observations equal 25 (4 + 5 + 8 + 7 + 1 = 25)

By averaging the bottom and upper interval bounds, we can also determine each interval's midpoint. As an illustration, the first interval's midway (10-19) is as follows:

Midpoint: (14.5) (10 + 19) / 2

This may be done for each interval, and to display the midpoints, we can add a third column to the table.

The cumulative frequency, which is the overall frequency as we progress from the shortest interval to the longest interval, can then be calculated. The cumulative frequency can be displayed in the table by using a fourth column.

The finished table is shown here:

Interval Frequency Midpoint Cumulative Frequency

10-19 4 14.5 4

Answer & Step-by-step explanation:

To multiply these two binomials, we can use the distributive property as follows:

(2x+5)(3x+1) = 2x(3x+1) + 5(3x+1)

Now, we can simplify each term:

2x(3x+1) = 6x^2 + 2x

5(3x+1) = 15x + 5

Putting these back together, we get:

(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5

Simplifying the middle two terms, we get:

(2x+5)(3x+1) = 6x^2 + 17x + 5

Therefore, the expression that is equivalent to (2x+5)(3x+1) is 6x^2 + 17x + 5.

Algebraic expression that shows the amount Ms. Jackson will pay for the small truck for the week is $340 + 0.30m.

An algebraic expression does not contain an equal sign and cannot be solved like an equation, but it can be simplified or manipulated using algebraic rules. For example, the expression 2x + 3y is an algebraic expression, where x and y are variables.

The amount that Ms. Jackson will pay for the small truck for the week can be expressed as the weekly fee plus the cost of driving the truck for the number of miles driven.

Let's call the weekly fee "wf" and the cost per mile driven "cpm". Then, the total amount that Ms. Jackson will pay can be expressed as:

wf + cpm × m

From the table, the weekly fee for a small truck is $340 and the cost per mile driven is $0.30. So, the algebraic expression for the total amount that Ms. Jackson will pay for a small truck for the week can be expressed as:

wf + cpm × m = $340 + $0.30 × m = $340 + 0.30m

The diagonal length of a right rectangular prism is given by the formula (l2 + w2 + h2) units. The length of the diagonal of this rectangular box is 5√2 cm.

Therefore, the equation for the diagonal length of a right rectangular prism is (l2+w2+h2), where l is the length, b is the breadth, and h is the height.

d2 = l2 + w2 + h2

Take the square root of either side of the equation to find the value of d:

d =  √(d2) = √(l2 + w2 + h2)

d = √(l2 + w2 + h2)

The diagonal length is as follows given that the rectangular box in question is 6 cm x 8 cm x 5 cm in size:

d = √(36 + 64 + 25)

d = √(125)

d = √(62.5)·√(2)

d = 5√(2)

Therefore, the length of the diagonal of this rectangular box is 5√2 cm.

An approximate size which does not represent any of the actual dimensions of the unit is nominal value.

The phrase "nominal number" is said to be quite new and rarely used. It seems to have come from the statistical phrase "nominal data," which is reportedly defined as data revealing "...merely declarations of qualitative category of membership," as it is used in school textbooks. The meaning of the word "nominal" in this use is "name."

Nominal numbering is mathematically a one-to-one and onto function from a set of named objects to a set of numbers, which may change (typically growing) over time. It is a function because each named object is assigned a single number; it is one-to-one because different objects are assigned different numbers; and it is onto because every number in the set at a given time has a single named object associated with it.
